Solve for x: 2/5 = x/24

lord [1]

Answer:

x=9.6

Step-by-step explanation:

We are given the proportion:

$\frac{2}{5}=\frac{x}{24}$

We are asked to solve for x. Therefore, we must isolate x on one side of the proportion.

x is being divided by 24. The inverse of division is multiplication. Multiply both sides of the proportion by 24.

$24*\frac{2}{5}=\frac{x}{24}*24$

$24*\frac{2}{5}=z$

$24*0.4=x$

$9.6=x$

$x=9.6$

x is equal to 9.6 The complete proportion is $\frac{2}{5}=\frac{9.6}{24}$

Chaz is a 79.2 pound dog that was just adopted. Based on his foster home his daily energy intake is 1,840 kcal. Chaz’s new owner

zimovet [89]

Answer:

option (c)5 and $\frac{\textup{1}}{\textup{4}}$ cups

Step-by-step explanation:

Given:

Weight of Chaz = 79.2 pounds

Daily energy intake requirement = 1,840 kcal

Energy present in different brand food = 3,523 kcal/kg

Therefore,

the amount of food required = $\frac{\textup{Daily energy intake requirement}}{\textup{Energy present in different brand food}}$

the amount of food required = $\frac{\textup{1,840}}{\textup{3,523}}$

the amount of food required = 0.52228 kg

also,

1 kg = 1000 grams

therefore,

the amount of food required = 0.52228 × 1000 = 522.28 grams

now,

A cup of food weighs 100 grams

hence,

the number of cups required = $\frac{\textup{the amount of food required }}{\textup{Amount of food per cup}}$

the number of cups required = $\frac{\textup{522.28}}{\textup{100}}$

the number of cups required = 5.2228 ≈ 5 and $\frac{\textup{1}}{\textup{4}}$ cups

Hence, the correct answer is option (c)

THE AP CALCULUS EXAM SCORES WERE RELEASED IN JULY. THE SECONDARY MATH SPECIALIST PREPARED THE BOX PLOT SHOWN TO PRESENT THE SCOR

Ganezh [65]

Answer : option A

To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile

Inter quartile range is the middle 50% of the given range of scores.

The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%

From the diagram , we can see that

Upper quartile = 89

lower quartile = 65

So range is 65% to 89%

Solve the following system of equations for x:

nikitadnepr [17]

Answer:

x=0.5

Step-by-step explanation:

2x+y= -2

and

4x+y= -8 so...

2x+y= -2 = 4x+y= -8

2x+4x= 6x

y+y=2y

-2+-8= -10

6x+2y= -10

2y- -10= 12

6x=12

6/12=0.5

x=0.5
