Answer:

A. 4√3

Step-by-step explanation:

All of the right triangles in this geometry are similar, so the ratios of hypotenuse to short side are the same:

(8+4)/x = x/4

48 = x^2 . . . . . . . . . multiply by 4x

In country A, about three times as many cars are manufactured per day than in country B. If the total number of these cars manu

Helga [31]

Answer:

country a = 19,812 cars

country b = 6,604 cars

Step-by-step explanation:

a = country a

b = country b

the 2 eqations are:

a + b = 26,416

a = 3b

now substitute 3b for a in the first equation:

3b + b = 26,416

add the variables:

4b = 26,416

now divide 26,416 by 4 (26,416/4)

b = 6,604

so country b has 6,604 cars

to find country b, substitute the number of cars in country b (which is 6,604) in the second equation:

a = 3b

a = 3 × 6,604

a = 19,812

so country a has 19,812 cars

Five devied by three forths

bija089 [108]

Answer:

$6\dfrac{2}{3}$

Step-by-step explanation:

$\dfrac{5}{\dfrac{3}{4}} = \dfrac{5}{1}\times\dfrac{4}{3}=\dfrac{20}{3}=6\dfrac{2}{3}$

When dividing fractions, you just need to remember that all you need to do is get the inverse of the divisor and multipy.

So for the problem

5 = divident

3/4 = divisor

So we get the inverse of 3/4 which is 4/3 and then multiply.

Look above to see the process.

A phone company is offering several different prepaid data plans.

yulyashka [42]

The data plan that has the cheapest deal is given by the ratio of the data

plan price to the GB allocated.

The deal that has the cheapest price per GB is B. Prepaid Single Phone Plan $45 for 16 GB.

The given phone data plans are;

$\begin{tabular}{|l|cl|}&Prepaid Single Phone Plan&Prepaid Family Plan\\ a&\$30 for 1 GB &\$30 for 1 GB\\b& \$35 for 6 GB & \$40 for 6 GB\\ c&\$45 for 16 GB&\$50 for 16 GB\\d & \$65 for Unlimited Data & \$70 for Unlimited Data\end{array}\right]$

The price per GB are;

Plan a = $30 ÷ 1 = $30 per GB

Plan b = $35 ÷ 6 = $5.8 $\overline 3$ per GB and $40÷ 6 = $6. $\overline 6$ per GB for Family Plan

Plan c = 45 ÷ 16 = $2.8125 per GB and $3.125 per GB

Plan d = $65 for Unlimited Data = 65 ÷ ∞ ≈ 0; $70 for Unlimited Data = 0

Therefore, the plan with the cheapest price per GB from the given option is option B. Prepaid Single Phone Plan $45 for 16 GB.
