Answer:
54 cans
Step-by-step explanation:
8 Tennis ball launchers.
Each hold 27 balls.
One can = 3 balls.
We have 27 * 8 total balls which is equivalent to 216.
We want to find 3/4 of the total which is 216 * 0.75.
This is then = to 162
Since one can holds 3 balls.
162/3 = 54 cans.
Therefore, to fill the total of 3/4 of launchers within a lesson, 54 cans of tennis balls will be needed.
Answer:
Number of cans is 6.75
Step-by-step explanation:
According to the question,
One launcher holds 27 tennis balls
3/4 launcher hold y tennis balls
Cross multiply
Y= 3/4×27
Y= 81/4
Y= 20.25 tennis balls
To determine the number of cans
One can holds 3 tennis balls
Z can holds 20.25 tennis balls
Cross multiply
3z= 20.25
Z= 20.25/3
Z=6.75 cans

Answer:
Answer is 5
Step-by-step explanation:
if you have any doubts see the image
The Pythagorean Theorem was used on a right triangle with sides of length 4 to find that the hypotenuse has a length approximately equal to 5.7.
Explanation:Here, your task is to apply the Pythagorean Theorem which states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). In this case, both a and b are given as 4. We can therefore calculate c as follows:
First, square the lengths of both a and b: 4^2 + 4^2 = 16 + 16Combine like terms: 16 + 16 = 32Find the square root of the sum to find c: sqrt(32) is approximately 5.7 (to the nearest tenth).Learn more about Pythagorean Theorem here:https://brainly.com/question/19649203

11x-3 = x-13
11x-3 -x = x-13 -x
10x-3 = -13
10x-3 +3 = -13 +3
10x = -10

z varies directly as x². If z=8 when x=2, find z when x=7
Answer:
98
Step-by-step explaination:
For this question, it is a direct variation. Hence, the equation would be formed accordingly, and the constant k would also be used.
z varies directly as x²
z= kx² where k is the constant
z = 8
x = 2
Putting the figures in the equation, we have
8=2²(k)
8= 4k
Dividing both sides by 4, we have
k = 8/4
k = 2
Solving for z now, we substitute k with 2. And x with 7
z=kx²
z = 2(7²)
z= 2(49)
z= 98
If it were indirect variation, the constant would have been 1/k. We also have other types of variation, Indirect variation, partial variation and joint variation.

What is the y-intercept (b value) of a line that is PERPENDICULAR to the line y = -x- 2and through
the point (-3,-7)
Answer:
The y -intercept is the point (0, -4).
Step-by-step explanation:
The slope of the perpendicular line = -1/m
= -1/-1 = 1.
So it is y = x + b.
To find b we substitute the point (-3, -7):
-7 = -3 + b
b = -7 + 3 = -4.
The y -intercept is the point (0, -4).

A cylindrical pipe has a circumference of 16cm
Calculate the diameter of the pipe
Please show method cleary
Step-by-step explanation:
pi×diamiter = circumference
pi÷circumference = diamiter
3.14159265358979 (pi) ÷ 16
Calculate the diameter of a cylindrical pipe with a circumference of 16cm using the formula C = πd. Hence the diameter of the pipe is approximately 5.09 cm.
The circumference of a cylindrical pipe is related to its diameter through the formula C = πd, where C is the circumference, π is Pi (approximately 3.14159), and d is the diameter. Given that the circumference is 16 cm, we can use the formula to solve for the diameter:
16 = πd
16 = 3.14159d
d = 16 / 3.14159 ≈ 5.09 cm
Therefore, the diameter of the pipe is approximately 5.09 cm.

A cylindrical water tank has a radius of 5 feet and a height of 10 feet. The volume of water in the tank is 565.2 cubic feet.
What percent of the tanks volume is filled with water?
About 71.96% of the cylindrical water tank, with a radius of 5 feet and a height of 10 feet, is filled with water when it contains 565.2 cubic feet of water.
To determine what percent of the tank's volume is filled with water, we must first calculate the total volume of the cylindrical tank using the formula for the volume of a cylinder: V = (pi)r²h. Here, the radius r is 5 feet, and the height h is 10 feet.
The total volume V of the tank is:
V = (pi)(5 feet)²(10 feet) = 3.14159 times 25 times 10 = 785.398 cubic feet
Now, since the volume of water in the tank is given as 565.2 cubic feet, we can calculate the percent of the tank's volume that is filled with water by dividing the volume of water by the total volume of the tank and then multiplying by 100 to convert to a percentage. So the calculation becomes:
Percent filled = ([tex]\frac{565.2}{785.398}[/tex]) times 100
Percent filled approx 71.96%
Therefore, about 71.96% of the tank's volume is filled with water.

In the above figure, m∠AOC = 26° and m∠BOD = 2x + 32. If ∠AOC and ∠BOD are vertical angles, what is the value of x?
The value of x is -3.
Step-by-step explanation:
It is given that the angles ∠AOC and ∠BOD are vertical angles.The vertical angles have same measure of angles.Therefore, ∠AOC is equal to ∠BOD.⇒ 26° = 2x+32
⇒ 2x = 26-32
⇒ 2x = -6
⇒ x = -6/2
⇒ x = -3
Substitute x=-3 in ∠BOD = 2x+32
∠BOD = 2(-3)+32 = 26°

The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
[tex]$f(x)=x^{2}+15[/tex] and [tex]f(x)=64[/tex]
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
[tex]x^2+15=64[/tex]
Subtract 15 from both sides of the equation.
[tex]x^2+15-15=64-15[/tex]
[tex]x^2=49[/tex]
49 can be written as 7².
[tex]x^2=7^2[/tex]
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.

-8x+5y=43
-8x+4y=36

[tex]x=-1\\y=7[/tex]
Step-by-step explanation:
Given equations:
[tex]-8x+5y=43[/tex] Equation:1
[tex]-8x+4y=36[/tex] Equation:2
As the coefficients of 'x' are same which will eliminate the terms of 'x':
Subtracting Equation:2 From Equation:1
[tex]-8x+5y-(-8x+4y)=43-36\\\\-8x+5y+8x-4y=7\\\\5y-4y=7\\\\y=7[/tex]
Putting value of 'y' in either equation:1 or 2
Putting y=7 in equation:2
[tex]-8x+4y=36[/tex]
[tex]-8x+4(7)=36\\\\-8x+28=36[/tex]
Subtracting '28' from both side:
[tex]-8x+28-28=36-28\\\\-8x=8\\[/tex]
Changing the sides:
[tex]8x=-8[/tex]
[tex]x=\frac{-8}{8} \\\\x=-1[/tex]
The values are :
[tex]x=-1\\y=7[/tex]

Natasha bought paintbrushes and paint for a total of $71 to paint a fence. The brushes cost $3.50 per brush and the paint cost $50. How much did each paint brush cost?
Natasha paid $4 per paintbrush
Natasha paid $17.50 per paintbrush
Natasha paid $6 per paintbrush
Natasha paid $21 per paintbrush
Answer:
Step-by-step explanation:
Cost of paint brushes= Total cost - cost of paint
= 71 - 50 = $21
No.ofpaint brushes =21/3.50 = 21*10/3.5*10
= 210/35 = 6
Answer:
Natasha paid $6 per paintbrush
Step-by-step explanation:
Cost for paint brusheswe can make use of variables
p = paint
b = brushes
bought paintbrushes and paint for a total of $71. . The brushes cost $3.50 per brush and the paint cost $50
we can create an equation from the information
3.5b + 50p = 71
since 1 paint is bought
3.5 b + 50 (1) = 71
3.5b = 71 - 50
3.5b = 21
b = 21/3.5
b = 6
paintbrush costs $ 6
