Answer:

61.7

Step-by-step explanation:

Let the number be x

% increase in the number : 7

Thus , actual increase in number will be 7% of x = 7/100 of x = 7x/100

Thus, new number with 7% increase = x+ 7x/100

given that value of new number with 7% increase is 66

Thus,

x+ 7x/100 = 66

=> (100x+7x)/100 = 66

=> 107 x = 66*100

=> x = 6600/107 = 61.682

Thus, original number is 61.682

but we have to find the number to nearest tenth .

original number is 61.7

It is not correct. 

The student found the volume by multiplying the base area with the height. He forgot to divide it by 3.

Formula to find the volume of the pyramid = 1/3 base area x height

volume = 1/3 x 92 x 54 = 1656 square meters

VashaNatasha [74]
$1,800 (10%) = $180 
jay pays 10% of the expenses beyond the deductible so you multiply the amount beyond the deductible by 10%.
$1,800 - $180 = $1,620 
or
$1,800 (90%) = $1,620
you subtract what jay pays from the total or you multiply the total by 90%

jay pays $180 of the expenses past the deductible (not including his $200 deductible) and his insurance company pays $1,620.
