Answer:

First picture - 20.42 m

Second picture - 12.9 m

Step-by-step explanation:

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

$V=b^2\frac{h}3$

Where,

b = base - 3.5 m

h = height - 5 m

Thus,

$V=3.5^2\frac{5}{3}$

$20.41667m^3$ ≈ $20.42m^3$

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

$V=b^2\frac{h}3$

Where,

b = base - 3 m

h = height - 4.3 m

Thus,

$V = 3^2\frac{4.3}{3}$

$12.9m^3$

Hats and mittens are on sale at the store! One woman was able to buy 5 hats and 4 pairs of mittens for $30.

aalyn [17]

The price of one hat is $2 and one pair of mittens is $5

Step-by-step explanation:

Hats and mittens are on sale at the store!

One woman was able to buy 5 hats and 4 pairs of mittens for $30
Another woman purchased 3 pairs of mittens and 2 hats for $19
The price of one hat is x
The price of one pair of mittens is y

We need to find x and y

∵ One woman was able to buy 5 hats and 4 pairs of mittens for $30

∵ The price of one hat is x

∵ The price of one pair of mittens is y

- Multiply 5 hats by x and 4 pairs of mittens by y and equate

their sum by 30

∴ 5x + 4y = 30 ⇒ (1)

∵ Another woman purchased 3 pairs of mittens and 2 hats for $19

- Multiply 2 hats by x and 3 pairs of mittens by y and equate

their sum by 19

∴ 2x + 3y = 19 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -2 and equation (2) by 5 to eliminate x

∵ -10x - 8y = -60 ⇒ (3)

∵ 10x + 15y = 95 ⇒ (4)

- Add equations (3) and (4)

∴ 7y = 35

- Divide both sides by 7

∴ y = 5

Substitute the value of y in equation (1) or (2) to find x

∵ 2x + 3(5) = 19

∴ 2x + 15 = 19

- Subtract 15 from both sides

∴ 2x = 4

- Divide both sides by 2

∴ x = 2

The price of one hat is $2 and one pair of mittens is $5
