The answer is D.

If you multiply them all together the answer (without simplifying), it should equal 210/9, you then simplify the numerator and denominator by 3 and you get 70/3.

Answer:

Step-by-step explanation:

Given

$\frac{5}{3}$ × $\frac{2}{3}$ × $\frac{21}{1}$

Multiply numerators/ denominators

= $\frac{5(2)(21)}{3(3)(1)}$

= $\frac{210}{9}$

Cancel the numerator/denominator by dividing both by 3

= $\frac{70}{3}$ → D

=> 3x + 90 = 180

=> 3x = 180 - 90

=> 3x = 90

$= > x = \frac{90}{3}$

A fruit bowl contains apples, oranges, and bananas. The radius of one of the oranges is 1.25 inches. What is the approximate vol

Elden [556K]

Answer:

8.18 cubic inches

Step-by-step explanation:

An orange is a sphere so you will use the formula for the volume of a sphere.

V= 4 /3 * π * r^3 r^3= 1.25* 1.25 * 1.25= 1.953

V= 4/3* 3.14 * 1.953 = 8.176=8.18

Andrea bought 1 2/5 pounds of avocados at $4.20 per pound and 2 1/

guapka [62]

Answer:

$14.43¢

Step-by-step explanation:

We are given; $1\frac{2}{5}$ pounds, 1 pound = $4.20 and $2\frac{1}{4}$ pounds,1 pound = $3.80 that Andrea bought.

Now we need to find her total cost. To do that, we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert $1\frac{2}{5}$ to a decimal. It is 1.4. Now we can set up a graph.

Avocados

$\frac{4.2}{1}=\frac{x}{1.4}$

Switch sides

$\frac{x}{1.4}=\frac{4.2}{1}$

Apply rule: $\frac{a}{1}=a$

$\frac{x}{1.4}=4.2$

Multiply both sides by 1.4

$\frac{1.4x}{1.4}=4.2\cdot \:1.4$

Simplify

$x=5.88$

So, her cost for avocados is $5.88¢

Now we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert $2\frac{1}{4}$ to a decimal. It is 2.25. Now we can set up a graph.

Asparagus

$\frac{3.8}{1}=\frac{x}{2.25}$
