⅔ x 6/7 ÷ 8/14 help please

ahrayia [7]

Answer:

Step-by-step explanation:

$\frac{2}{3} *\frac{6}{7}$ ÷ $\frac{8}{14}$

= $\frac{2}{3} *\frac{6}{7} *\frac{14}{8}$

= $\frac{2}{3} *\frac{6}{7} *\frac{7}{4}$

= $\frac{2*6*7}{3*7*4}$

= $\frac{84}{84}$

The population of a suburb is 4000 people. The population of the suburb

Lisa [10]

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

$P=4000\times 2^d$

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

$P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000$

So, if d = -2, then the population of the suburb is equal to 1000.

Find the area of the entire figure.

MakcuM [25]

Answer:

$\large\boxed{A=171.555\ in^2}$

Step-by-step explanation:

We have the right triangle and the trapezoid.

The formula of an area of a right triangle:

$A_{triangle}=\dfrac{ab}{2}$

a, b - legs

We have the length of the legs 12in and 13.42 in. Substitute:

$A_{triangle}=\dfrac{(12)(13.42)}{2}=80.52\ in^2$

The formula of an area of a trapezoid:

$A_{trapezoid}=\dfrac{(b_1+b_2)h}{2}$

b₁, b₂ - bases

h - height

We have the length of the bases 18in and 11.75in and the length of the height 6.12in. Substitute:

$A_{trapezoid}=\dfrac{(18+11.75)(6.12)}{2}=\dfrac{(29.75)(6.12)}{2}=91.035\ in^2$

The area of the figure:

$A=A_{triangle}+A_{trapezoid}$

Substitute:

$A=80.52+91.035=171.555\ in^2$
