In january the depth of the lake was 1,126 feet, in august the depth was 675.6 feet, what is the precentage of decrease of the depth of the lake from january to august

The percent decrease is 40%.

Step-by-step explanation:

percent change = (new value - old value)/(old value) * 100

If the result is negative, the change is a percent decrease. If the result is positive, the change is a percent increase.

old value = 1,126 ft

new value = 675.6 ft

percent change = (675.6 ft - 1,126 ft)/(1,126 ft) * 100

percent change = (-450.4 ft)/(1,126 ft) * 100

percent change = -0.4 * 100

percent change = -40%

Since the result is negative, it is a percent decrease.

The percent decrease is 40%.

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
