Find the total surface area of a rectangular prism with dimensions of 8 ft x 4 ft x 3 ft.
Kryger [21]
Hi,

To find area of rectangular prism do this.

a = 8 \\ b = 4 \\ c = 3 \\ s = 2 \times (a \times c) + 4 \times (a \times b) \\ s = 2 \times (8 \times 3) + 4 \times (8 \times 4) \\ s = 2 \times 24 + 4 \times 32 \\ s = 48 + 128 \\ s = 176

Hope this helps.

Rico bought 3 adult tickets and 5 child tickets for a total of $50.
aliina [53]

Step-by-step explanation:

3x + 5y = 50

x + 5y = 31

use substitution

x = 31-5y

3(31-5y) +5y = 50

93 -15y + 5y = 50

93 - 10y = 50

--10y = -43

y = 43/10 = $4.30 for kids

now solve for x

x + 5(4.30) = 31

x + 21.5 = 31

x = $9.5 for adults

Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen we
vaieri [72.5K]

x represents the number of lawns weeded by Gwen and y represents the number of dogs walked by Fabio.

Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog.

So, for x number of weeds, Gwen earned 12x and for y number of dogs walked, Fabio earned 9y.

They need at least $510 to purchase the new gaming station.

Therefore,

12x + 9y ≥ 510

Also, the number of dog walks that Fabio has scheduled should not be more than twice the number of yards Gwen has scheduled to weed.

Therefore,

y ≤ 2x

Also, Fabio will walk at least 25 dogs.

Therefore,

y ≥ 25

Hence, the constraints are:

12x + 9y ≥ 510

y ≤ 2x

y ≥ 25
