In a museum there is a sculpture in the shape of a cylinder. The cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?

V = π(9)2h

V =π (9h ) 2

V = π(18)2h

V = π(18h) 2

1). the submarine is descending 100 feet per minute. this is because the line decreases 100 on the y axis when the x axis increases by 1.
2). the submarine is descending 50 feet per minute. this is because the line decreases 50 on the y axis when the x axis increases by 1.
3). y=15x this is because the slope increases by 15 on the y axis when 1 is increased on the x axis. the y intercept is 0. this means that every hour of piano lessons they get paid $15.

Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to Start Fraction 7 over 25 End Fraction. She writes the equation y = x + Start Fraction 7 over 25 End Fraction. What error is Roni making?

A. She should have written y = negative x + StartFraction 7 over 25 EndFraction so that x and y have a constant sum.

B. She should have written x y = StartFraction 7 over 25 EndFraction so that x and y have a constant product.

C. She should have written y = StartFraction 7 over 25 EndFraction x so that x and y have a constant quotient.

D. She should have written y = StartFraction 7 over 25 EndFraction so that y has a constant value.

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0

In order to find the area of a triangle, you must do 1/2 base x height.

So to plug in the numbers, you will have 1/2 x 1 x 1.5.

1/2 x 1 = 0.5 and 0.5 x 1.5 = 0.75
