Answer:

97,656,250

Step-by-step explanation:

The first term, a(1), is 10. The next is 5 times greater. And so on. Thus, the common ratio is 5, and the general formula for this sequence is

a(n) = a(1)*5^(n -1).

Therefore,

a(11) = 10*5^(11 - 1) = 10*5^10 = 97,656,250

A trapezoid has an area of 95 square meters. If the bases are 7 meters and 12 meters what is the height of the trapezoid

Colt1911 [192]

ANSWER

The is 10 is meters

EXPLANATION

The area of a tra-pezoid can be calculated using the formula;

$Area= \frac{1}{2} \times (sum \: of \: bases) \times height$

We substitute the values to get,

$95= \frac{1}{2} \times (7 + 12) \times height$

$2 \times 95= 19 \times height$

$\frac{190}{19} = height$

$height = 10$

The height is 10 meters.
