Answer:

Option C. 32/3

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $p*x=k$ or $p=k/x$

we know that

For p=14, x=16

Find the value of k

$k=p*x$

substitute the values

$k=(14)*(16)=224$

The equation is equal to

$p=\frac{224}{x}$

Find the value of p when x=21

substitute the value of x in the equation

$p=\frac{224}{21}$

simplify

Divide by 7 both numerator and denominator

$p=\frac{32}{3}$

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in

pentagon [3]

Compound inequality combines multiple single inequalities.

The solution and interpretation of the inequality is:

$x > 50$ and $x < 150$ . Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates.

We have:

$110 < 2x + 10$ and $2x + 10< 310$

Solve for x in both inequalities

$110 < 2x + 10$

$110 -10 < 2x$

$100 < 2x$

Divide both sides by 2

$50 < x$

Rewrite as:

$x > 50$

Also, we have:

$2x + 10< 310$

$2x< 310 - 10$

$2x< 300$

Divide by 2

$x < 150$

So, the solutions to the inequalities are:

$x > 50$ and $x < 150$

This means that Ryan needs to consume more than 50 but less than 150 grams of carbohydrates.

Hence, (a) is correct

Daniella collected 4242 bushels of peas from her garden today. Tomorrow she will send \frac{3}{7} 7 3 of the peas to market. H

Vaselesa [24]

Answer: 24

Step-by-step explanation:

Amount of bushels of peas collected = 42

Fraction that'll be sent to market = 3/7

Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7

The number of bushels that'll be kept will be:

= Fraction that'll be kept × Total number of bushels collected

= 4/7 × 42

= 24
