Answer: It would be Second leg = 15
Step-by-step explanation:
From my understanding, you are supposed to find the second leg of the right triangle by Pythagoras theorem.
Hypotenuse: 25
One leg: 20
Second leg: x
Pythagoras theorem: hypotenuse² = adjacent² + opposite²
c² = a² + b²
25² = 20² + b²
b² = 25² - 20²
b² = 625 - 400
b² = 225
b = √225
b = 15
Therefore, the second leg of the right triangle is 15.
Find the value of x and find whether the angles or supplementary or complementary.
Answers
Answer:
Both angles add up to 90° so they are complementary angles, x = 55
Step-by-step explanation:
=> We know that both angles add to 90°, so the equation will be;
(x - 20) + (x) = 90
=> Using algebra if solved all the way down, "x" will be 55.

The graph shows Marcia's walk.
Which statement best describes what Marcia could be doing on the interval from B to C?
A. Marcia is running home.
B. Marcia is walking home.
C. Marcia is turning a corner.
D. Marcia is stopping to rest.
Answers
Answer:
D. Marcia is stopping to rest
Step-by-step explanation:
At intervals B to C, we can see that Marcia's distance from home has not risen nor dropped. We can safely assume that she is not moving. Of course, time has not stopped, because the line continues to move from left to right. So, Marcia is likely stopping to rest for a moment.

A sphere has a radius of 5 feet. Find the volume of the sphere. Leave your answer in terms of pie. Then use 3.14 for pie and round the volume to the nearest 10th. Volume in terms of pie=? Volume in using 3.14=?

Solution: V=4
3πr3=4
3·π·53≈523.59878 and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers
The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
Given,
r = 5 ft
pi = 3.14
Formula
the volume of sphere is:
V = 4/3 * 3.14 * r^3
Solution
V = 4/3 * 3.14 * 5^3
V = 4/3 * 3.14 * 125
V ≈ 523.59878
V ≈ 523.6 m^3
as, we get,
V≈523.59878
and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers.
Hence, The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

Letter C, E, and F: 2 8/10, 2.8, and 28/10
Step-by-step explanation: The shaded pillars/rectangles inside the squares account for the fractions. In this question, there are 10 pillars per square and 2 shaded in squares. Since there are two full squares, there are two wholes. In the third block, there are only 8 shaded. Because 8 out of ten are shaded, the fraction would be 8/10 (said as eight tenths). Overall, there are two wholes (the shaded squares) and 8/10 of a whole. Therefore, it is 2 8/10. 0.8 equals 8/10 (you can determine it by the way it is said ex: you would say “zero and ...” (and = decimal) “... eight tenths” or just “eight tenths” for .8, and 8/10 is said the same way). Since 2.8 and 2 8/10 are equal, 2.8 would also be an answer. 28/10 would be another correct answer because the two wholes/squares each have 10 pillars. In total, there are 20 pillars for the two wholes. If the 8/10 (8 out of 10) is added, the total would be 28/10. Hope this helps!
A box is to be made where the material for the sides and the lid cost $0.20 per square foot and the cost for the bottom is $0.05 per square foot. Find the dimensions of a box with volume 20 cubic feet that has minimum cost.
Please answer in length , width and height in ft
Answers
Answer:
Let x represent the edge dimension of the square base in feet. Then the area of the base or lid is x², and the height of the box is 5/x². Total cost is then ...
... cost = cost of lid + 4×(cost of one side) + cost of bottom
... cost = 0.2x² + 4×(0.2x(5/x²)) + 0.5x²
... cost = 0.7x² + 4/x
We can differentiate this with respect to x and set that derivative to zero. This will give us the x-value at which the cost is a minimum.
... d(cost)/dx = 1.4x -4/x² = 0
... x³ = 4/1.4
... x = ∛(20/7) ≈ 1.419
Then the height of the box is
... height = 5/x² ≈ 5/2.01351 ≈ 2.483
The box is 1.491 ft square and 2.483 ft high.
______
The average cost of the top and bottom is (0.2 +0.5)/2 = 0.35 per square foot. The overall cost will be minimized when the average cost of each face is the same. That is, the areas of the lateral faces will be equal and must be 0.35/0.2 = 1.75 times the area of the top or bottom to make the average cost of a lateral face equal to that of the top or bottom. Hence, the base will be square, and the box will be 1.75 times as high as it is wide or deep. The base edge dimension is then ∛(5/1.75) ≈ 1.419 ft.
