The money would be multiplied by a factor of 16 after 28 years

<h3>How to determine the factor?</h3>

The rate is given as:

Rate = Double every 7 years

There are 4 7 years in 28 years.

So, the factor would be:

Factor = Rate^4

This gives

Factor = 2^4

Evaluate

Factor = 16

Hence, the money would be multiplied by a factor of 16 after 28 years

Given the following diagram, find the required measure.

Zielflug [23.3K]

Answer:

∠ 5 = 40°

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and supplementary, thus

∠ 2 = 180° - ∠ 1 = 180° - 140° = 40°

∠ 5 and ∠ 2 are alternate angles and congruent , thus

∠ 5 = 40°

99 pencils cost \$7.74$7.74dollar sign, 7, point, 74. Which equation would help determine the cost of 666 pencils? Choose 1 answ

balu736 [363]

Answer:

$\large \boxed{\text{A) } \dfrac{6}{x} = \dfrac{9}{\$7.74}}$

Step-by-step explanation:

9 pencils cost $7.74

6 pencils cost x

The ratios are

$\dfrac{9}{6} = \dfrac{\$7.74}{x}$

According to the alternendo property,

$\dfrac{9}{6} = \dfrac{\$7.74}{x} \Rightarrow \dfrac{9}{\$7.74} = \dfrac{6}{x}\\\\\text{The correct answer is $\large \boxed{\mathbf{ \dfrac{6}{x} = \dfrac{9}{\$7.74}}}$}$
