Answer:
There is no basis for comparison because the effect of the other variables that are not being studied are not minimized
Step-by-step explanation:
The rate at which each type of ball bounce are;
Tennis balls;
The height to which the ball is must rebounds ≈ 111 cm
The height from which the ball is dropped = 200 cm
Surface = Steel plate
Basketballs;
The height to which the ball must rebounds ≈ 5.35 inches
The height from which the ball is dropped = 72 inches
Surface = Wooden floor
Squash balls
The height to which the ball must rebounds ≈ 29.5 inches
The height from which the ball is dropped = 100 inches
Steel plate at 70°
Therefore, given that the experimental are performed with different variables of height from which each type of ball is dropped, the surface to which the ball is dropped, the angle of the surface to which the ball is dropped, there is no controlled variable to provide a basis for comparison
Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3
Answer:
7 1/5 m
Step-by-step explanation:
Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3
Volume of a rectangular prism = Length × Width × Height
Length = Volume/ Width × Height
Length = 60 m³/2 1/2 m × 3 1/3 m
Length = 60 m³/8 1/3 m²
Length = 60 m³÷ 8 1/3 m²
= 60 m³ ÷ 25/3 m²
=( 60 × 3/25 )m
= 180/25 m
Length = 7 1/5 m

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,340 ft Determine the flag's width and length if the length is 390 ft greater than the width.
Answer:
Step-by-step explanation:
L=W+390, W=L-390
P=2(W+L), P=2340
2(L-390+L)=2340
2L-390=1170
2L=1560
L=780ft

Dave said that these triangles are similar. Is it false or true?
Answer:
false
Step-by-step explanation:
the sum of the angles is 180, for the first triangle B is 180-(60+79)= 41°. and for the second F = 180-(60+42) = 72°. therefore they're not equal / similar.

All you have to do is find the slope, which is given in the question and then count it and see what line goes with the slope you were given.
1/3 is the slope so count that to check your work, and it works out :)
Solve this inequality:
16x - 33x < -12x + 30
A. x < -6
B. x > 6
C. x > -6
Answer:
x > -6.
Step-by-step explanation:
16x - 33x < -12x + 30
Add 12x to both sides:
16x - 33x + 12x < 30
-17x + 12x < 30
-5x < 30
x > 30/-5
x > -6
(Note the inequality signs flips because we are dividing by negative 5).
We wish to analyze the temperature during summer months for the northeaster part of the US proportion or mean
Answer:That would be mean

Pls help find the surface area
Answer:
114
Step-by-step explanation:
17 + 8 = 25
25 ÷ 2 is for one triangle.
25 ÷ 2 = 12.5
12.5 x 4 = 50
(4, because there are 4 triangles)
Then, 8 x 8 is for the middle square, which is 64
64 + 50 = 114
So, The surface area is 114

What is the y-intercept of line x = -8?
Answer:
There is no y-intercept.
Step-by-step explanation:
x = -8 has an undefined slope which means that it will never have a y-intercept unless it is x = 0.
if prism A and B have a ratio of similarity of 6:11, what is the volume of prism B if the volume of prism A is 96 cubic units
Answer:
176cubic units
Step-by-step explanation:
a:b
6:11
a=96
6/11=96/x
6x=1056(96×11)
x=176 cubic units

Solve the equation for x:
5x – 4 – 9x
4(x - 5)
Answer:
x = 2
Step-by-step explanation:
5x – 4 – 9x = 4(x - 5)
-4x -4 = 4x -20
-4x -4x = -20+4
-8x = -16
x = -16/-8
x = 2

A highway sign shows a speed limit of 60 miles per hour. Which of the following car speed measurements represent the same level of accuracy compared to the speed limit sign? Check all that apply. A. 64 mph B. 56 mph O C. 48 mph O D. 68 mph
Answer:
B and C
Step-by-step explanation:
IT is found that B. 56 mph and C. 48 mph car speed measurements represent the same level of accuracy compared to the speed limit sign.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken
We can see that As the speed limit on the highway is 60 miles per hour and the speeds mentioned above are below the speed limit.
The legal top speed at which a vehicle may travel on a specific section of road is determined by speed limits for road traffic, since they are utilized in the most of countries.
On a traffic sign, it is known that the maximum allowed speed is typically displayed and expressed in kilometers per hour (km/h) or miles per hour (mph).

Answer:
y=-x-5(instead of 5 it could be any number)
Step-by-step explanation:
Given the slope of the line containing the points (7 , b) and (-2 , 5) is 4/9, find the value of b
Answer: b=9
Step-by-step explanation: To find the slope we use: y2-y1/x2-x1
Which would then be: 5-b/-2-7= 5-b/-9
Then we have to find a number for b that would give us -4 as the numerator. That number would be 9
This would give us 4/9 which is the slope we already had.
PLZZZ HELP MEEE YALL .!.!.!.!
Answer:
Step-by-step explanation:
Area of the rectangle = length * width
= 10 * 5
= 50 m²
Area of the smaller rectangle that is white color = 7 * 2
= 14 m²
Triangle:
base = b = 5 m
Height = h = 16 - 10 = 6 m
Area of triangle = [tex]\frac{1}{2}*b*h\\[/tex]
[tex]= \frac{1}{2}*5*6\\\\= 5*3\\\\= 15 m^{2}[/tex]
Area of shaded area = area of bigger rectangle - area of smaller rectangle + area of triangle
= 50 - 14 + 15
= 21 m²
