A coach buys a uniform and a basketball for each of the 12 players on the team. Each basketball costs $8. The coach spends a total of $288 for uniforms and basketballs.
Enter the cost, in dollars, of 1 uniform.
Answers
16
Step-by-step explanation:
if you multiply 12 by 8 you get 96 so then you would subtract 96 from 288 and get how much he would spend on all of them then i think you would need to divide 192 from 12 and get 16.so i think the answer is 16 correct me if im wrong

Answer:
the answer is 21
Step-by-step explanation:
if one of the factors is 7 and it's between 20 and 30
then it can be 21 or 28
7×3=21 and 7×4=28
now the factors of 21: 1, 3, 7, 21 (4 factors)
the factors of 28: 1, 2, 4, 7, 14, 28 (6 factors)

Find the length of CA to the nearest tenth of a foot
Answers
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{CA}[/tex] = [tex]\frac{2.6}{CA}[/tex] ( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA = [tex]\frac{2.6}{tan40}[/tex] ≈ 3.1 ft ( to the nearest tenth )

A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?
Answers
Answer:did u get the answer?
Step-by-step explanation:sorry
The measurement of total surface area of the sculpture in square feet is 814 square feet.
What is the surface area of a cylinder?The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh
where r is the radius of the circular base and h is the height of the cylinder.
Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.
So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.
The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.
Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.
The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.
So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.

can the sides of a triangle have lengths 3, 4, and 7?
Answers
Answer:
The length of the third side of a triangle must always be between (but not equal to) the sum and the difference of the other two sides. ... Therefore, the third side length must be greater than 4 and less than 8. Because 7 is greater than 4 and less than 8, it is possible for these to be the side lengths of a triangle.
Step-by-step explanation:
The sides of length 3, 4 and 7 does not form triangle.
What is a triangle?Three edges, three angles, and three vertices are the characteristics of a triangle in geometry. In geometry, it is a basic figure.
The sum of the angles of a triangle is always 180°
Given that,
Sides of a triangle are 3, 4 and 7.
Since, the one side of a triangle is greater than the difference of other two sides and less than sum of the two sides.
Implies that,
If side 3 is taken, then 3 should greater than difference of 7 and 4, also less than sum of 7 and 4.
Implies that,
7 - 4 < 3 < 7 + 4
3 < 3 < 11
Here, the condition does not satisfy. Therefore, The given lengths do not make triangle.

What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
Melissa and Robbie are flying remote control gliders.
The altitude of Melissa's glider, h(s), in feet, is modeled by this function:
m(s) = 0.4(s³ - 11s² + 31s - 1)
Plug s = 6 seconds in the function m(s)
m(6) = 0.4(6³ - 11(6)² + 31(6) - 1)
m(6) = 0.4(216 - 396 + 186 - 1)
m(6) = 0.4(5)
m(6) = 2 feet
From the graph of Robbie:
At s = 6 seconds
Altitude = 13 feet (approximately)
Thus, Robbie reaches the greater maximum altitude in the first 6 seconds after launch option (C) Robbie's glider is correct.

Answer:
The correct answer is 2 ( 5 × w )
Explanation:
Area of a rectangle = length × width
The length = 5 feet
The width = w feet
So the area = 5 × w
Then, he has to double the length and width, so its 2 times the length and width. So the new expression will be:
Area = 2 ( 5 × w )
