Simplified 20/24 would be 5/6 because we divide by 4.
Simplified 12/28 would be 3/7 because we divide by 4.

What is the percent of change from 60 to 87?

stiv31 [10]

Answer:

45% increase

Step-by-step explanation:

The new number (87) is bigger than the original number (60), so this is a percent increase.

To find the percent of change, which in this case is a percent increase, take the change amount and divide by the original, then convert to a percent.

Subtract to find the change.

87 - 60 is 27.

27 is the amount of change.

change/original

= 27/60

= .45

Times by 100 to change to a percent.

.45 × 100

= 45%

Sergio039 [100]

The area of the red piece of paper is A= 4(2*4)= 4*8= 32 in^2.
The area of the blue piece of paper is A= 3*7=21 in^2. You subtract 21 from 32 and the difference is 11. So 11in^2 is visible.

Answer:

2 seconds
72 feet

Step-by-step explanation:

The usual equation used for the vertical component of ballistic motion is ...

h(t) = -16t² +v₀t +h₀

where v₀ is the initial upward velocity, and h₀ is the initial height. Units of distance are feet, and units of time are seconds.

Your problem statement gives ...

v₀ = 64 ft/s

h₀ = 8 ft

so the equation of height is ...

h(t) = -16t² +64t +8

For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Then the axis of symmetry of the height equation is ...

t = -64/(2(-16)) = 2

The object will reach its maximum height after 2 seconds.

The height at that time will be ...

h(2) = -16(2²) +64(2) +8 = 72

The maximum height will be 72 feet.
