x is the number od doubling periods ( which is given as every 7 years)

28 years / 7 = 4 doubling periods in 28 years

so x = 4

so you now have:

f(x) = 8000 * 2^4

2^4 = 16

so 8000 * 16 = $128,000 would be the answer

Please give brainliest.

yuradex [85]

Answer:

width of a singles court = 27 feet

Step-by-step explanation:

Width of a doubles tennis court = 36 feet

Width of a singles tennis court = 75% of 36

$width = 75\% \times 36 \\ width = \frac{75}{100} \times 36 \\ width = \frac{3} {4} \times 36 \\ width = \frac{108}{4} = 27$

Fill in the Blanks

tatyana61 [14]

Answer: This would fill 4 and 4/9 containers.

Explanation:

Since we have given that

Quantity of walnuts in a container is given by

$6\frac{2}{3}=\frac{20}{3}\ pounds$

Quantity of walnuts which divided equally into containers is given by

$1\frac{1}{2}=\frac{3}{2}\ pounds$

Now, number of containers they would fill is given by

$\frac{\frac{20}{3}}{\frac{3}{2}}=\frac{20\times 2}{3\times 3}=\frac{40}{9}$

When we change it into mixed fractions we get,

$\frac{40}{9}=4\frac{4}{9}$

So, blank will be filled with '4'.

Adjacent angles in parallelograms are supplementary angles thus :

$x + 130 = 180$

$x = 180 - 130$

$x = 50$
