andrey2020 [161]

Answer:1968ft^2

Step-by-step explanation:

Perimeter(p)=178feet

P=2L+2w

178=2L+2w

178=2(L+w)

L+w=178 ➗ 2

L+w=89.............(1)

W+7=L

L-w=7...................(11)

L+w=89... ..........(1)

L-w=7...................(11)

Subtract (11) from (1)

2w=89-7

2w=82

w=82 ➗ 2

w=41 width=41feet

Substitute w=41 in (11)

L-w=7

L-41=7

L=7+41

L=48feet

Area= length x width

Area=48 x 41

Area=1968ft^2

balandron [24]

Answer:

25 capsules.

Step-by-step explanation:

We are told that Joan has a prescription for 100 Theophylline capsules. Joan informs the pharmacist that she only has enough money to purchase ¼ of the prescription today.

To find the number of capsules that Joan will pay for today, we will find 1/4 of 100.

\text{The number of capsules that Joan will pay for today}=\frac{1}{4}\times 100

\text{The number of capsules that Joan will pay for today}=25

Therefore, Joan will pay for 25 capsules today.
