enot [183]

Answer:

30.7 ft

Step-by-step explanation:

An equilateral triangle with area 43.5 has a height of 8.68 not 8.5

I will do the problem as written even though it is not a possible equilateral triangle

---------------------------------------------

a = (1/2)bh

43.5 = (1/2)b(8.5)

43.5 = 4.25b

b = 43.5/4.25

b = 10.2352941176

-----------------------

p = 3b

p = 3 * 10.2352941176

p = 30.7058823528

~ 30.7 ft

The trapezoid below has been enlarged by a scale of 1.5. A trapezoid with an area of 36 inches squared. What is the area of the

Viktor [21]

Answer:

B. $81\text{ in}^2$

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.

The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

$1.5\times 1.5=2.25$

$\text{Area of new trapezoid}=2.25\times 36\text{ in}^2$

$\text{Area of new trapezoid}=81\text{ in}^2$

Therefore, the area of the enlarged trapezoid would be $81\text{ in}^2$ and option B is the correct choice.

Find the sum of the first 40 terms of a geometric sequence where the first term is 16 and the common ratio is 1.1. 704 7,081.480

Lilit [14]

Step-by-step explanation:

The nth term of a geometric progression can be determined by using the formula:

Tn=arn−1

where: a = first term and r = common ratio

Substitute the given values of first term and common ratio into the formula:

Tn=arn−1

T5=(40)(0.5)5−1

T5=(40)(0.5)4

T5=(40)(0.0625)

T5=2.5
