Sam wants to build a wooden deck on his patio, which is in the shape of a parallelogram. The
area of the patio is 350 ft2. Find the base. Round your answer to the nearest foot.
Hint : Use A = bh.
We may calculate our answer using fractions and the fact that the base is 18.3 feet.
What are fraction ?The components of a whole or group of items are represented by fractions. A fraction consists of two components.
The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection.
The denominator is the figure that appears below the line. It displays the total number of identical objects in a collection or the total number of equal sections the whole is divided into.
There are three different methods to express a fraction: as a fraction, as a percentage, or as a decimal. Let's examine each of the three representational styles.
According to our question-
The patio is 280 square feet in size. locate the base.
Height = 5x Area = 280 feet square
Base = 6x
The parallelogram A's area can be expressed mathematically as;
Base + height equals area.
A = b×h
the values of area, base, and height are substituted.
280 = 5x × 6x = 30x^2 \sx^2 = 280/30 \sx = √(280/30)
Given that the base is 6x,
swapping out x's value.
Base = 6x = 6(√(280/30))
Base=18.3 feet
18.3 ft tall is the base

nn-slice pizza. One of the friends, Harris, ate
1
11 fewer slice than he received.
How many slices of pizza did Harris eat?
Write your answer as an expression.
The expression representing the number of slices Harris ate is 1/11.The expression 1/11 represents the Proportion of slices Harris ate compared to the total number of slices.
The total number of slices in the pizza as "n". Since the pizza was evenly divided among 44 friends, each friend received n/44 slices.
Harris ate 1/11 fewer slices than he received. Therefore, Harris received (n/44) - (1/11) slices.
To determine the number of slices Harris ate, we need to subtract the number of slices he received from the number of slices he ate. Thus, the expression representing the number of slices Harris ate is:
(n/44) - (n/44 - 1/11)
To simplify this expression, we can combine the fractions:
(n/44) - (n/44) + (1/11)
The two terms with n/44 cancel out, leaving us with:
1/11
Therefore, the expression representing the number of slices Harris ate is 1/11. the specific number of slices Harris ate, we need to know the value of "n," the total number of slices in the pizza. The expression 1/11 represents the proportion of slices Harris ate compared to the total number of slices, but we cannot determine the actual value without knowing "n".
In conclusion, the expression representing the number of slices Harris ate is 1/11, but the specific number of slices cannot be determined without knowing the total number of slices in the pizza (denoted by "n").

I have an order to administer nitroglycerin 10mcg/min continuous infusion. The bottle of nitroglycerin available is 50mg in 250 ml of D5W. At what rate would you set the IV pump to infuse at
Answer:
The IV pump infusion rate = 0.05ml per minute
Step-by-step explanation:
available concentration = 50 mg per 250 ml of D5W
This means that
250 ml of D5W contains 50 mg
note that
mg = milligram
mcg = microgram
250 ml = 50mg
1ml = 50/250 mg
1ml = 0.2mg
Next, let us convert from milligram (mg) to microgam (mcg) since the unit of administration is in mcg.
1 mg = 1000 mcg
∴ 0.2 mg = 1000 × 0.2
= 200mcg
Therefore the available concentration 200mcg/ml
required concentration/min = 10
since 1 ml = 200mcg
1 mcg = (1 ÷ 200) ml
1 mcg = 0.005 ml
∴ 10 mcg = 0.005 × 10 = 0.05 ml
10 mcg is contained in 0.05 ml of the solution
Therefore, the IV pump infusion rate = 0.05ml per minute

40 PTS!!!! A single-serving juice boxes measure 10cm by 7cm and 5cm. A manufacturer wants to shrink wrap four boxes together for sale. Which of the two arrangements of the boxes with use the least amount of plastic wrap? Show your work
Both arrangements use the same amount of plastic wrap, with a total surface area of 1240 cm².
To determine which arrangement of the four juice boxes uses the least amount of plastic wrap, we need to consider the total surface area that needs to be covered in each arrangement.
Arrangement 1:
In this arrangement, we can place the four juice boxes in a 2x2 square configuration, with two boxes stacked horizontally and two boxes stacked vertically. Let's calculate the total surface area to be covered:
Surface area of a single box = 2(lw) + 2(lh) + 2(wh)
= 2(107) + 2(105) + 2(7*5)
= 140 + 100 + 70
= 310 cm²
Since we have four boxes in this arrangement, the total surface area to be covered is:
Total surface area = 4 * 310 cm²
= 1240 cm²
Arrangement 2:
In this arrangement, we can stack the four juice boxes in a single column, one on top of the other. Let's calculate the total surface area for this arrangement:
Surface area of a single box is the same as in the previous arrangement:
Surface area of a single box = 310 cm²
Since we have four boxes stacked vertically, the total surface area to be covered is:
Total surface area = 4 * 310 cm²
= 1240 cm²
Therefore, both arrangements use the same amount of plastic wrap, with a total surface area of 1240 cm².

The average score of students in the first group is 39, the second group is 32, and the third group is 43. If the numbers of students in the three groups are 24, 26, and 27, respectively, find the average score of all students.
The average score of all students, calculated by taking a weighted average based on the number of students in each group, is 38. The overall performance is slightly below the group averages.
The average score of students in the first, second, and third groups are 39, 32, and 43, respectively. There are 24 students in the first group, 26 students in the second group, and 27 students in the third group.
To find the average score of all students, we need to take a weighted average of the scores in each group, with the number of students in each group as the weights.
Here's how to do it: First, we calculate the total number of students:24 + 26 + 27 = 77. Then, we calculate the total score across all students: 39*24 + 32*26 + 43*27 = 936 + 832 + 1161 = 2929
Finally, we divide the total score by the total number of students to get the average score:2929/77 = 38. The average score of all students is 38.
This means that the overall performance of all the students is slightly below the average of the scores in each group.

If the scale factor between the sides is 5, what are the scale factors between the surface areas and volumes?
If the scale factor between the sides is 5, the scale factor between the surface areas will be 25, and the scale factor between the volumes will be 125.
When the scale factor between the sides of a shape is given, the scale factors between the surface areas and volumes can be determined by considering the relationship between the dimensions.
Let's denote the scale factor between the sides as "k."
For surface area:
The surface area of a shape is determined by the square of its linear dimensions. Therefore, the scale factor for the surface area will be k^2. In this case, if the scale factor between the sides is 5, the scale factor between the surface areas will be 5^2 = 25.
For volume:
The volume of a shape is determined by the cube of its linear dimensions. Hence, the scale factor for the volume will be k^3. Given that the scale factor between the sides is 5, the scale factor between the volumes will be 5^3 = 125.
Therefore, if the scale factor between the sides is 5, the scale factor between the surface areas will be 25, and the scale factor between the volumes will be 125.

Elena wants to prove that the measures of the 3 angles in a triangle always

My best explanation to this question is:
Elena has summed the total of all three angles in the straight angle to get 180°; <DAB, <BAC , and <CAE. But this does not mean a total of three angles will ALWAYS equal 180°. If one angle is greater than the other two, then there is a possible chance the angle will not be 180°. If the angles are scalene, then there is a greater chance the angle may not be 180°.
This may be wrong, so you don’t have to come up with my response exactly, just modify it to what you need. Wish you luck.
The measures of the 3 angles in a triangle always sum to 180 degrees.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
We have to determine the prove that the measures of the 3 angles in a triangle always sum to 180 degrees.
We have been given that angles as
∠ DAB, ∠ BAC, and ∠ CAE.
Each 180-degree rotation takes line BC to a parallel line. So line DA is parallel to BC and line AE is also parallel to BC.
There is only one line parallel to BC that goes through point A, so lines DA and AE are the same lines.
Since line DE is parallel to line BC,
∵ alternate interior angles are congruent.
This represents that angle BAD also measures b" and angle CAE also measures c'. D
Since DE is a line, the 3 angle measures at point A would sum to 180 degrees.
So a + b + c = 180.
The fact that this explanation is dependent on the triangle we started with indicates that any triangle's sum of its three angles is always 180 degrees.
Therefore, the measures of the 3 angles in a triangle always sum to 180 degrees.

How many lbs. of mixed nuts that contain 70% peanuts must lea add to 13 lbs. of mixed nuts that contain 20% peanuts to make a mixture with 44% peanuts?
10 lbs of mixed nuts that contain 70% peanuts must lea add to 13 lbs. of mixed nuts that contain 20% peanuts to make a mixture with 44% peanuts.
Let x pounds be the amount of mixed nuts we require.
Amount of peanuts in this mix = 0.70x pounds.
Amount of peanuts in the 20% mix = 0.20 × 15 = 3 pounds.
So we have the equation:-
⇒ 0.70 x + 3 = 0.44 (x + 15)
⇒ 0.70 x + 3 = 0.44 (x + 15)
⇒ 0.70x + 3 = 0.44x + 6.6
⇒ 0.70x - 0.44x = 6.6 - 3
⇒ 0.36x = 3.6
⇒ x = 3.6 / 0.36
x = 10 lbs
Hence , 10 lbs of mixed nuts that contain 70% peanuts must lea add to 13 lbs. of mixed nuts that contain 20% peanuts to make a mixture with 44% peanuts.

A and B are supplementary angles. If mA = (3x - 28)° and
m/B = (x − 4)°, then find the measure of A.
Answer:
A = 131°
Step-by-step explanation:
Supplementary angles sum 180°
A + B = 180°
(3x - 28) + (x - 4) = 180
4x - 28 - 4 = 180
4x - 32 = 180
4x = 180 + 32
4x = 212
x = 212/4
x = 53
Then:
A = 3x - 28
A = 3*53 - 28
A = 159 - 28
A = 131°
B = x - 4
B = 53 - 4
B = 49°

What are the vertical asymptotes for the function f/x )= x 2 x 6 x 3 1?
The vertical asymptotes for the function f(x) = (x^2)(x-6)(x+3)^-1 are x=6 and x=-3.
The vertical asymptotes for the function f(x) = (x^2)(x-6)(x+3)^-1 are x=6 and x=-3. This is because the denominator can be factored into two linear expressions: x-6 and x+3. When either of these expressions equals 0, the fraction becomes undefined and a vertical asymptote is created. To find the asymptotes, set each linear expression in the denominator equal to 0 and solve for x. For x-6, x=6; for x+3, x=-3. Therefore, the vertical asymptotes of the function are x=6 and x=-3. When x is close to either of these values, the fraction will become very large, making the graph approach the vertical asymptotes without ever touching them.
