the lot is 90 feet by 110 feet. the fence is to be 6 feet tall. cost for the fence is $3.00 per linear foot, plus $.40 per square foot for labor. what is the total cost of the fence
the lot is 90 feet by 110 feet. the fence is to be 6 feet tall. cost for the fence is $3.00 per linear foot, plus $.40 per square foot for labor then the total cost of the fence is 8643 dollar
We have to sum the three distances to get the perimeter.
P= 90 ft + 110 ft+ 6 ft
P = 201 ft
And each foot of material cost $3.00
we get the cost with the distance and de cost of the material:
Cost = 201 ft * 3.00 $ per ft = $603
he needs $603.00 to fence her backyard garden
40 per square labor
then 201*40 = 8040
total = 8040+603= 8643

The perimeter of the base of a regular quadrilateral pyramid is P=30cm. Find the sum of all edges of this pyramid if the perimeter of a lateral face is 27.5cm
The sum of all edges of the regular quadrilateral Pyramid is approximately 66.68 cm.
The sum of all edges of a regular quadrilateral pyramid, we need to determine the number of edges in the pyramid and then calculate their total length.
A regular quadrilateral pyramid has a base that is a regular quadrilateral, meaning all sides of the base have the same length. Let's assume that each side of the base has a length of "a" cm.
The perimeter of the base is given as P = 30 cm, so each side of the base measures 30 cm divided by 4 (since there are four equal sides) which is 7.5 cm.
Now, let's consider the lateral face of the pyramid. A regular quadrilateral pyramid has four lateral faces, each of which is an isosceles triangle. The perimeter of a lateral face is given as 27.5 cm. Since there are three edges in each lateral face, the length of each edge is 27.5 cm divided by 3, which is approximately 9.17 cm.
Therefore, the sum of all the edges in the pyramid is calculated as follows:
Sum of edges = (4 × a) + (4 × 9.17)
Since we know that each side of the base (a) is 7.5 cm, we can substitute this value into the equation:
Sum of edges = (4 × 7.5) + (4 × 9.17)
= 30 + 36.68
= 66.68 cm
Hence, the sum of all edges of the regular quadrilateral pyramid is approximately 66.68 cm.

2) DE = 9.25 in
3) ∠EDC = 36°
4) ∠AEB = 108°
5) 11.5 in
Step-by-step explanation:
1) AD = BC = 9in
2) AC = BD (diagonals are equal)
⇒ BD = 14.25
⇒ BE + DE = 14.25
⇒ 5 + DE = 14.25
DE = 9.25
3) Since AB ║CD,
∠ABE = ∠EDC = 36°
4) ∠ABE = ∠BAE = 36°
Also ∠ABE + ∠BAE + ∠AEB = 180 (traingle ABE)
⇒ 36 + 36 + ∠AEB = 180
∠AEB = 108

suppose that the first goal in a gp problem is to make 3 x1 4 x2 approximately equal to 36. using the deviational variables d1- and d1 , what constraint can be used to express this goal?
To express the goal of making 3x1 + 4x2 approximately equal to 36 using deviational variables, we can define the constraint as follows:
d1 = 3x1 - 36
d2 = 4x2 - 36
In computer programming, a variable is an abstract storage location paired with an associated symbolic name, which contains some known or unknown quantity of information referred to as a value; or in simpler terms, a variable is a named container for a particular set of bits or type of data.
This constraint represents the deviation of each variable from the target value of 36. By subtracting 36 from each side of the equation, we ensure that the goal is to make the deviation (d1 and d2) equal to zero. This means that when d1 = 0 and d2 = 0, the expression 3x1 + 4x2 will be equal to 36, indicating that the goal has been achieved.

The IQR is the best measure of variability, and it equals 8.
The IQR is the best measure of variability, and it equals 2.5.
The best measure of the center for this data is the median, and its value is 6.5.
We must take the data distribution into account in order to get the optimum centre measure for this data. With more data points above 6 and 7 than below, the line plot demonstrates that the data is not symmetrical.
Because it is unaffected by the extreme values in the dataset, the median is the best indicator of the centre in this situation.
The median, which in this example ranges between 6 and 7, is the dataset's middle value when it is ordered in order. Given that there are an equal number of data points, the median is determined by taking the average of the two middle values. This value is 6.5.

For the following set of data, find the percentage of data within 2 population standard deviations of the mean, to the nearest percent
chart is in the photo
Percentage of data within 2 population standard deviations of the mean is 68%.
To calculate the percentage of data within two population standard deviations of the mean, we need to first find the mean and standard deviation of the data set.
The mean can be found by summing all the values and dividing by the total number of values:
Mean = (20*2 + 22*8 + 28*9 + 34*13 + 38*16 + 39*11 + 41*7 + 48*0)/(2+8+9+13+16+11+7) = 32.68
To calculate standard deviation, we need to calculate the variance first. Variance is the average of the squared differences from the mean.
Variance = [(20-32.68)^2*2 + (22-32.68)^2*8 + (28-32.68)^2*9 + (34-32.68)^2*13 + (38-32.68)^2*16 + (39-32.68)^2*11 + (41-32.68)^2*7]/(2+8+9+13+16+11+7-1) = 139.98
Standard Deviation = sqrt(139.98) = 11.83
Now we can calculate the range within two population standard deviations of the mean. Two population standard deviations of the mean can be found by multiplying the standard deviation by 2.
Range = 2*11.83 = 23.66
The minimum value within two population standard deviations of the mean can be found by subtracting the range from the mean and the maximum value can be found by adding the range to the mean:
Minimum Value = 32.68 - 23.66 = 9.02 Maximum Value = 32.68 + 23.66 = 56.34
Now we can count the number of data points within this range, which are 45 out of 66 data points. To find the percentage, we divide 45 by 66 and multiply by 100:
Percentage of data within 2 population standard deviations of the mean = (45/66)*100 = 68% (rounded to the nearest percent).
Therefore, approximately 68% of the data falls within two population standard deviations of the mean.

Nathan is trying to break his own world record for eating the most hotdogs in 10 minutes. He needs to eat more than 72 hotdogs to break his record. After 1 minute of competition, Nathan has eaten 10 hotdogs. Write an inequality to represent the number of hotdogs he needs to eat per minute for the remaining 9 minutes
Nathan needs to eat more than 6.89 hotdogs per minute for the remaining 9 minutes to break his record. Since he cannot eat a fraction of a hotdog, he needs to eat at least 7 hotdogs per minute.
Let's represent the number of hotdogs Nathan needs to eat per minute for the remaining 9 minutes as x. We can set up an inequality to represent the situation.
Nathan has already eaten 10 hotdogs in the first minute. For the remaining 9 minutes, he will eat 9x hotdogs (where x is the number of hotdogs per minute). To break his record, he needs to eat more than 72 hotdogs in total. So the inequality will look like this:
10 + 9x > 72
Now we can solve for x:
9x > 62 (subtract 10 from both sides)
x > 62/9 (divide both sides by 9)
x > 6.89
So, Nathan needs to eat more than 6.89 hotdogs per minute for the remaining 9 minutes to break his record. Since he cannot eat a fraction of a hotdog, he needs to eat at least 7 hotdogs per minute.

the operation of matrix-vecotr multiplication is linear since the properties a(u v) = au av and a(cu) = c(au) hold for all vectors u and v
Matrix-vector multiplication is a linear operation because it satisfies the properties of scalar multiplication and vector addition, which are a(u+v) = au + av and a(cu) = cau, where a is a scalar and u and v are vectors.
Matrix-vector multiplication is a fundamental operation in linear algebra, where a matrix is multiplied by a vector to produce another vector. This operation is considered linear because it adheres to certain properties.
The first property is scalar multiplication, which states that multiplying a vector u by a scalar a and adding it to another vector v (a(u+v)) is equivalent to multiplying u by a (au) and v by a (av) separately and then adding the results (au + av). In other words, the operation distributes over vector addition.
The second property is the distributive property of scalar multiplication, which states that multiplying a vector u by a scalar c and then multiplying the resulting vector (cu) by another scalar a is equivalent to multiplying u by the product of the two scalars (cau). This property allows the scalar multiplication to be distributed over scalar multiplication.
These properties ensure that matrix-vector multiplication preserves the linearity of the underlying vector space. They enable the manipulation and analysis of systems of linear equations, transformations, and other mathematical operations involving matrices and vectors.

Answer: Not lying cause what's the point of lying to someone asking for help. The answer is x = -7
Step-by-step explanation: X= -7 because if you look at a graph with negative and positive on it along with the Y and the X on it. Then you'll see that the middle of the plus is zero the left of the middle (going down the X axis) is negative. And the right side of the X axis is positive and the line is on the negative side of the X axis. That's why instead of it being Y= -7 ( which is NOT the answer) is wrong because the line is over the X axis instead of the Y axis.
A ball of 2kg strikes a wall with a velocity 1m/s at an angle 30∘ with the horizontal as shown in the figure below. It reflects at the same angle from the wall in 0.1 s. Force exerted on the ball will be:A20√3NB15√3 NC10√3 ND5√3 N
To calculate the force exerted on the ball, we can use the formula and Therefore, the force exerted on the ball is not among the given options (A20√3N, B15√3N, C10√3N, or D5√3N). The correct answer is 34.64 N.
Force = (change in momentum) / time
First, let's calculate the initial momentum of the ball:
Initial momentum = mass x velocity
Initial momentum = 2kg x 1m/s
Initial momentum = 2kg m/s
Next, let's calculate the final momentum of the ball:
Final momentum = mass x velocity (since the ball reflects at the same angle and has the same magnitude of velocity, the momentum is the same as the initial momentum)
Final momentum = 2kg x 1m/s
Final momentum = 2kg m/s
The change in momentum is the difference between the final and initial momentum:
Change in momentum = final momentum - initial momentum
Change in momentum = 2kg m/s - 2kg m/s
Change in momentum = 0
Finally, we can calculate the force exerted on the ball:
Force = (change in momentum) / time
Force = 0 / 0.1s
Force = 0N
Therefore, the answer is D) 5√3 N.
Given the information provided, we need to find the force exerted on the 2kg ball that strikes a wall at a 30-degree angle with a velocity of 1m/s and reflects at the same angle in 0.1 seconds.
Step 1: Determine the horizontal and vertical components of the initial velocity.
Initial horizontal velocity (Vx) = V * cos(30) = 1 * cos(30) = 0.866 m/s
Initial vertical velocity (Vy) = V * sin(30) = 1 * sin(30) = 0.5 m/s
Step 2: Determine the horizontal and vertical components of the final velocity.
Since the ball reflects at the same angle, the final vertical velocity will be the same, but the horizontal velocity will have the opposite direction.
Final horizontal velocity (Vx') = -0.866 m/s
Final vertical velocity (Vy') = 0.5 m/s
Step 3: Calculate the change in horizontal and vertical velocities.
ΔVx = Vx' - Vx = -0.866 - 0.866 = -1.732 m/s
ΔVy = Vy' - Vy = 0.5 - 0.5 = 0 m/s
Step 4: Calculate the net change in velocity (ΔV).
ΔV = sqrt((ΔVx)^2 + (ΔVy)^2) = sqrt((-1.732)^2 + (0)^2) = 1.732 m/s
Step 5: Determine the acceleration of the ball.
Acceleration (a) = ΔV / time = 1.732 / 0.1 = 17.32 m/s²
Step 6: Calculate the force exerted on the ball using Newton's second law (F = m * a).
Force (F) = mass (2kg) * acceleration (17.32 m/s²) = 34.64 N
