A child's toy is in the shape of a square pyramid. The pyramid stands 20 inches tall and each side of the base measures 24 inches.
Half of the surface area of the pyramid is black and the remainder is yellow.
What is the surface area of the toy that is yellow?
Enter your answer, rounded to the nearest tenth, in the box.
The surface area of the toy that is yellow is 847.8 inches², to the nearest tenth.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
A square pyramid is a three dimensional object with one square base and 4 four triangular lateral faces.
Total surface area of the pyramid = Area of the base + 4(area of triangular face)
Base length = 24 inches
Base area = 24² = 576 inches²
Height of the pyramid = 20 inches
The slant height, l of the triangle can be found as,
l = [tex]\sqrt{(\frac{a}{2} )^2+h^2}[/tex], where a is the length of the base and h is the height.
l = [tex]\sqrt{12^2+20^2}[/tex]
= √544
= √(34 × 16)
= 4√34 inches
Area of 4 triangular faces = 4 ([tex]\frac{1}{2}[/tex] × 24 × 4√34)
= 2 × 24 × 4√34
= 192√34 inches²
Total surface area = 192√34 inches² + 576 inches²
= (192√34 + 576) inches²
= 1695.5428 inches²
Surface area of toy that is yellow = 1695.5 / 2 = 847.8 inches², to the nearest tenth.
Hence the surface area of the yellow part of toy is 847.8 inches², to the nearest tenth.

What percent of 112 is 21?
21 is 18.75% of 112. Percentage is widely used to represent a difference or contrast between two numbers.
What do you mean by percentage?A percentage is a way to express a number as a fraction of 100. It is often used to express a change or a comparison between two numbers. The symbol for percentage is %, and it represents the fraction of 100. For example, 50% means 50 out of 100, or 1/2.
Percentages are often used to represent increases or decreases in a quantity, as well as ratios and proportions. For example, if the price of a product increases by 20%, it means the new price is 120% of the original price, or 1.2 times the original price. If a student scores 80% on a test, it means they answered 80 out of 100 questions correctly.
Percentages can be easily converted to decimals or fractions by dividing by 100. For example, 50% can be written as 0.5 as a decimal or 1/2 as a fraction. Similarly, 75% can be written as 0.75 as a decimal or 3/4 as a fraction.
To find what percent 21 is of 112, we can use the formula:
Percent = (Part ÷ Whole) x 100
In this case, the part is 21 and the whole is 112, so:
Percent = (21 ÷ 112) x 100
Percent = 0.1875 x 100
Percent = 18.75
Therefore, 21 is 18.75% of 112.

PLS ANSWER ASAP! 1ST CORRECT ANSWER GETS BRAINLIEST!!!! (If it's not correct, I'll add a comment saying so.)
Answer:
Below
Step-by-step explanation:
3/4 (1/6 x +16) = 3/7 (4 3/8 - 21) expand L side and compute R side
3/24 x + 12 = - 7.125 Subtract 12 from both sides of the equation
3/24 x = -19.125 Multiply both sides by 24/2
x = -153
THIS EQUATION DOES SHOW x = -153
PERHAPS you MEANT this :
3/4 (1/(6x) +16) = 3/7 (4 3/8 - 21) Expand L side and compute R side
3/(24x) + 12 = - 7.125 subtract 12 from both sides
3/(24x) = -19.125 re-arrange
3 / (-19.125) = 24 x divide both sides by 24
3/ (-19.125 * 24) = x = - 1/153

With a volume of 700 cubic feet and a height of 9 feet , the radius of cylinder is 3.49 feet after rounding to nearest hundredth.
To find the radius of a right cylinder, you need to know its volume and height. The formula for the volume of a cylinder is given by:
V = πr^2h
Where r is the radius, h is the height, and π is approximately equal to 3.14.
Given that the volume is 700 cubic feet and the height is 9 feet, we can substitute these values into the formula:
700 = πr^2 * 9
Dividing both sides by π * 9:
700 / (π * 9) = r^2
Taking the square root of both sides:
√(700 / (π * 9)) = r
Using a calculator and rounding to the nearest hundredth, we find that:
r ≈ 3.49
So the radius of the cylinder is approximately 3.49 feet.

nails cost $12.99 per box, and screws cost $14.99 per box. a carpenter must buy both nails and screws and can spend no more than $60. which system of inequalities represents this situation, where n represents the number of boxes of nails and s represents the number of boxes of screws?
The cost of nails can be represented as 12.99n, and the cost of screws can be represented as 14.99s.
The cost of buying nails and screws can be represented by a system of inequalities where "n" represents the number of boxes of nails and "s" represents the number of boxes of screws.
The cost of one box of nails is $12.99 and the cost of one box of screws is $14.99. Hence, the cost of "n" boxes of nails is represented by 12.99n and the cost of "s" boxes of screws is represented by 14.99s. The carpenter has a budget of $60 and can spend no more than that.
Therefore, the combined cost of buying nails and screws must be less than or equal to $60. This requirement can be represented by the inequality 12.99n + 14.99s <= 60.
To make the calculation easier, we can also express the inequality as n + s <= 4.62, where 4.62 is obtained by dividing $60 by $12.99. This system of inequalities represents the carpenter's budget constraint and helps to determine the number of boxes of nails and screws that can be purchased within the budget.
