Answer:

x>3

Step-by-step explanation:

  • First distribute the 3 to the inside of the parentheses:
  • 3 \times x = 3x \\  3 \times 4 = 12
  • you should then get 3x+12>21
  • next you want to subtract over 12 from both sides:
  • 3x + 12  > 21\   \\ 3x > 9
  • then divide 3 over on both sides
  • 3x > 9 \\ 9 \div 3 = 3 \\ x > 3
  • you should then get x>3 for your final answer

Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyra
mina [271]

Answer:

Akira needs 45 square inches of  gold foil to cover the chair free including the bottom​

<u>Step-by-step explanation:</u>

Total surface  =  surface area of the base square + area of 4 triangles

<u>Step 1: The surface area of the base square</u>

surface area of the base = surface area of the square =  s^2

where s is the side length

The the surface area of the base  = 3^2 = 9 square inches

<u>Step 2: The surface area of the side triangles </u>

The area of the triangle = \frac{1}{2}\times \text{side length} \times \text{slant height}

On substituting the values,

The area of the triangle =\frac{1}{2} \times 3 \times 6

The area of the triangle = \frac{18}{2}

The area of the triangle = 9 square inches

Now the area of 4 triangles  =  4 x 9  = 36 square inches

Thus the total surface area  =  9 + 36 = 45 square inches

A ball is dropped from a height of 125 cm. Each time it hits the ground, it bounces
zalisa [80]

As a decimal 3/5 = 0.6

Multiply the height by 0.6:

1st bounce = 125 x 0.6 = 75

2nd bounce = 75 x 0.6 = 45

3rd bounce = 45 x 0.6 = 27

The answer is 27cm
