Samuel has an ant farm with a volume of 375 cubic inches. The width of the ant farm is 2.5 inches and the length is 15 inches. W

Alexxandr [17]

Answer:

Step-by-step explanation:

From the given information, it is clear that the shape of ant form is rectangular prism.

Let us write formula for volume of rectangular prism (ant form)

V = l x w x h

Use the formula to write an equation.

Plug V = 375, w = 2.5 and l = 15

375 = 15 x 2.5 x h

375 = 37.5 x h

Divide both sides of the equation by 37.5

375/37.5 = (37.5 x h)/37.5

10 = h

Hence, the height of the form is 10 inches.

The price of gas on Wednesday was $2.03/gallon. On Friday, the price of gas was $2.26. What is the percent change in the price o

Vika [28.1K]

Answer:

Percent change in the price of gas is $9.85\%$

Step-by-step explanation:

Percentage change equals the change in value divided by the absolute value of the original value, multiplied by $100$ .

$\text { Percentage Change }=\frac{\Delta V}{\left|V_{1}\right|} \times 100$

Here

$\Delta V=2.26-2.03\\\\=0.23\$/gallon$

$V_{1}=2.03\$/gallon$

The percent change in the price of gas

$=\frac{0.23}{2.03} \times100\\\\=9.85\%$

Percent change in the price of gas is $9.85\%$

Suppose , varies jointly with g and v, and j = 2 when g = 4 and v= 3.

kap26 [50]

Answer:

j = 44/3

Step-by-step explanation:

j varies jointly as g and v. This can be represented mathematically as:

$j \alpha gv\\j = kgv$ .............(1)

Where k is a constant of proportionality

j = 2 when g = 4 and v = 3

Substitute these values into equation (1)

2 = k * 4 * 3

2 = 12 k

k = 1/6

when g = 8 and v = 11:

j = (1/6) * 8 * 11

j = 44/3

Anna and Betty share 24 sweets in the ratio 3:5. How many sweets do they get each?

Alborosie

Answer:

Anna 9 and Betty 15

Step-by-step explanation:

sum the parts of the ratio , 3 + 5 = 8 parts

divide number of sweets by 8 to find value of one part of the ratio

24 ÷ 8 = 3 ← value of 1 part of the ratio , then

3 parts = 3 × 3 = 9

5 parts = 5 × 3 = 15

Anna gets 9 sweets and Betty gets 15
