Answer:

Step-by-step explanation:

# 21.

$\frac{8}{15}$ ÷ ( - 0.35 ) = - $\frac{8}{15}$ ÷ $\frac{35}{100}$ = - $\frac{8}{15}$ ÷ $\frac{7}{20}$ = - $\frac{8}{15}$ × $\frac{20}{7}$ = - $\frac{32}{21}$ (B).

# 22.

( $3\frac{1}{2}$ - $9\frac{3}{4}$ ) ÷ ( - 2.5 )

$3\frac{1}{2}$ = $3\frac{5}{10}$ = 3.5

$9\frac{3}{4}$ = $9\frac{3*25}{4*25}$ = $9\frac{75}{100}$ = 9.75

( 3.5 - 9.75 ) ÷ ( - 2.5 ) = ( - 6.25 ) ÷ ( - 2.5 ) = 2.5 (D).

Write the equation for a circle that satisfies the given conditions.

Alisiya [41]

The standard form of a circle is:

$(x-a)^2+(y-b)^2=r^2$

Your center is $(-10, -6)$ and your radius is $9$

Plug them into the equation and you get

$(x-(-10))+(y-(-6)) = 9^2$

$(x+10)^2 + (y+6)^2=81$

The correct answer is D.
