\frac{(3^-2)^2 * (5^2)^-3 * ( t ^-3)^2 }{( 3^-2) ^5 ( 5^3) ^-2 ( t ^-4)^3}

= \frac{\frac{1}{1265625^t12} }{1}

= \frac{\frac{1}{992640625^t6} }{1}

= \frac{992640625^t6}{1265625}

= \frac{922640625tttttt}{1265625}

= 729t^6

Answer : 729t^6

A right circular cylindrical metallic rod is 15 inches tall. The radius of the base is 2 inches. What is the surface area of the
Artyom0805 [142]

Answer: Surface area = 68π inches²

Step-by-step explanation:

The formula for determining the total surface area of the circular cylindrical metallic rod is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylindrical rod.

h represents the height of the cylindrical rod.

π is a constant whose value is 3.14

From the information given,

Radius = 2 inches

Height = 15 inches

Therefore,

Surface area = (2 × π × 2²) + 2 × π × 2 × 15) = 8π + 60π

Surface area = 68π inches²

To write 81/450 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .

Your answer to the first one is incorrect.

We can cut the plan into two figures, a rectangle with side lengths of 4 cm and 5 cm and a rectangle with side lengths of 1 and 2 cm.

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(4 + 5)

P = 2(9)

P = 18

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(2 + 1)

P = 2(3)

P = 6

Add up the perimeters:

18 + 6 = 24

So the total perimeter is 24.

For the 2nd one, your answer is also incorrect.

We multiply 5 to the perimeter of the plans:

5 * 24 = 120

Not sure what the third one is asking.

For the fourth one we just multiply 'k' to the perimeter:

24 * k = 24k

Thepotemich [5.8K]

Answer:

Step-by-step explanation:

4y - 2(5 - y + 4) = 4y - 2(9 - y)

                         = 4y + 9*(-2) - y *(-2)

                         = 4y  - 18 + 2y      {Combine like terms 4y and 2y}

                         = 6y - 18

6y - 18 = 6*y - 6*3

           = 6(y - 3)

6y- 18 =  2 *3y - 2*9

          = 2(3y -9)

2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)

Others are not equivalent

Pre image ABCD was dilated to produce image A’B’C’D why is the scale factor from the pre image? Enter your answer in the box as
shepuryov [24]

The scale factor of the dilation from ABCD to A′B′C′D′ is 3.

Step-by-step explanation:

Step 1:

In the pre-image ABCD, the length of one of the sides is given as 14 units.

For the other shape A′B′C′D′, the same side as the previous shape is given as 8 units.

Step 2:

To determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In this case, it is the given length of the sides CD and C′D′.

So the scale factor = \frac{C^{1} D^{1} }{CD} = \frac{8}{14} = \frac{4}{7} .

So the shape ABCD is dilated by a scale factor of \frac{4}{7} to produce the shape A′B′C′D′.
