Answer: 990
Step-by-step explanation:
SA = 2LH + 2LW + 2WH
SA= 2(25•10) + 2(25•7) + 2(7•10)
SA= 990
The surface area of a rectangular solid will be 990 square feet.
What is the surface area of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as
SA = 2(LW + WH + HL)
We have length 25 feet, width 7 feet, and height 10 feet.
SA = 2(25 x 7 + 7 x 10 + 10 x 25)
SA = 2(175 + 70 + 250)
SA = 2(495)
SA = 990 square feet

Step 2: Shade to the left of –5 to represent less than –5.
A number line going from negative 10 to 0. An open circle is at negative 5. Everything to the left of the circle is shaded.
Step 3: Check work by substitution.
x = negative 5

Larry concludes that he must have shaded the number line in the wrong direction. Which best describes the situation?
Larry’s graph is incorrect. He should have used a closed circle at –5.
Larry’s graph is incorrect. He should have shaded to the right of –5 because the numbers less than –5 are to the right of –5.

Answer: Based on the given figure above, we can conclude that the triangle is an isosceles triangle. By definition, an isosceles triangle is a triangle that has at least two equal sides. Since this is an isosceles triangle, 8x-10 =6x. Now we can solve for x. So,
8x-10 =6x
8x-6x = 10
2x =10
x= 5.
Therefore, the value of x in the figure is 5. Hope this is the answer that you are looking for.

Use the graph to calculate the probabilities of the events given below.
(a) {at most three lines are in use}
(b) {fewer than three lines are in use}
(c) {at least three lines are in use}
(d) {between two and five lines, inclusive, are in use}
The probability of the event between two and five lines, inclusive, are in use is 0.85.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that,
x 0 1 2 3 4 5 6
p(x) 0.12 0.18 0.20 0.20 0.20 0.07 0.03
a) At most three lines are in use
Here we need to find the probability for x≤3.
P(x≤3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)
= 0.12+0.18+0.20+0.20
= 0.70
b) Fewer than three lines are in use
Here we need to find the probability for x<3.
P(x<3)=P(x=0)+P(x=1)+P(x=2)
= 0.12+0.18+0.20
= 0.50
c) At least three lines are in use
Here we need to find the probability for x≥3.
P(x≥3)=P(x=3)+P(x=4)+P(x=5)+P(x=6)
= 0.20+0.20+0.07+0.03
= 0.50
d) Between two and five lines, inclusive, are in use
Here we need to find the probability for 2≤x≤5.
P(2≤x≤5)= P(x=2)+P(x=3)+P(x=4)+P(x=5)
= 0.18+0.20+0.20+0.20+0.07
= 0.85
Therefore, the probability of the event between two and five lines, inclusive, are in use is 0.85.

Now we will set up the equation to solve for y2 +y2)/2 =
The coordinates of point B are (-3, 17).
The given equation is M = I₁ + I₂ = 31 + 32.
Now let's substitute in our given values:
(-2, 2) = ((-5 + x₂) / 2, (-5 + 2 + y₂) / 2)
We will now set up two equations to solve for our two unknowns, x₂ and y₂:
Equation 1: (-5 + x₂) / 2 = -4
Multiply both sides by 2:
-5 + x₂ = -8
Add 5 to both sides:
x₂ = -3
This gives us the x-coordinate of point B.
Equation 2: (-5 + 2 + y₂) / 2 = 7
Simplify:
(-3 + y₂) / 2 = 7
Multiply both sides by 2:
-3 + y₂ = 14
Add 3 to both sides:
y₂ = 17
This gives us the y-coordinate of point B.
Therefore, the coordinates of point B are (-3, 17).

Given that \(\frac{|z - 5i|}{|z + 5i|} = 1\) , show that z lies on the x-axis.
The proof that z lies on the x-axis is shown below
How to show that z lies on the x-axis.For z to lie on the x-axis, then the coordinate must be represented as (x, 0)
Given that
\(\frac{|z - 5i|}{|z + 5i|} = 1\)
We start by simplifying the given expression using the definition of the modulus of a complex number:
So, we have
\(\frac{|z - 5i|}{|z + 5i|} = \frac{\sqrt{(x - 0)^2 + (y - 5)^2}}{\sqrt{(x - 0)^2 + (y + 5)^2}} = 1\)
Where
z = x + yi or z = (x, y)
Squaring both sides of the equation above, we obtain:
\(\frac{(x - 0)^2 + (y - 5)^2}{(x - 0)^2 + (y + 5)^2} = 1\)
This gives
\(\frac{x^2 + (y - 5)^2}{x^2 + (y + 5)^2} = 1\)
By comparison, we have
\((y + 5)^2 = (y - 5)^2\)
Set y = 0 to test the equation
So, we have
\((0 + 5)^2 = (0 - 5)^2\)
25 = 25 --- true
The equation is true for y = 0
This means that
z = (x, 0)
Hence, z lies on the x-axis

Use proportional reasoning and show algebraic work.
Using proportional reasoning, we can predict that there will be 40 red candies in the large bag.
Using proportional reasoning, we can set up and solve the following equation to determine the number of red candies in the large bag:
P = Proportion of red candies in the large bag
R = Red candies in the small bag
R × (33/9) = P
12 × (33/9) = P
P = 40 red candies in the large bag

Given that, a group of 4 friends went to the fair. They each ordered a funnel cake and shared a large pack of candy that costed $6.50.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the cost of each cake be x.
They paid a total of $34.50.
Now, 4x+6.50=34.40
⇒ 4x = 34.40-6.50
⇒ 4x = 27.90
⇒ x = 27.90/4
⇒ x = $6.975

You take thirty measurements in order to find the length of a rod, you calculate the average and obtain the value L0. Supposed that now a different person takes twenty measurements as well of the same rod, then calculates the average and obtains the same L0 as you. Does it mean that both of you obtain a result with the same precision and accuracy
Answer:
Yes, it means that both of you obtain a result with the same precision and accuracy.
Step-by-step explanation:
It is provided that two different people took measurements in order to find the length of a rod.
The first person took 30 measurements.
The second person took 20 measurements.
Both the people got the same average length, i.e. L₀.
In statistics, a larger sample leads to an error free result.
So, for the first person the larger sample helped reducing the chance of any sort of error that may be present.
For the second person, the average is same as the first even when their sample size is less than the first.
This may happen because the sample was selected with a certain precision and accuracy.
Thus, both of them obtain a result with the same precision and accuracy.
