Here are two rectangles.

Sophie [7]

Answer:

$AB=9.5\ cm$

Step-by-step explanation:

step 1

Find the length side PQ

we know that

The area of rectangle PQRS is given by

$A=(PQ)(QR)$

$A=66\ cm^2$

$66=(PQ)(QR)$

substitute the value of QR

$66=(PQ)(12)$

solve for PQ

$PQ=66/12\\PQ=5.5\ cm$

step 2

Find the length side AB

we know that

The perimeter of rectangle ABCD is given by

$P=2(AB+BC)$

we have

$P=30\ cm\\BC=PQ=5.5\ cm$

substitute

$30=2(AB+5.5)$

solve for AB

$15=AB+5.5\\AB=15-5.5\\AB=9.5\ cm$

A nurse is to give the liquid medicine 3 times a day. The morning dose is 3/4 ounce, the noon dose is 1/2 ounce and the evening

arsen [322]

Answer:

she need 1/2 ounce more.

Step-by-step explanation:

The morning dose = 3/4 ounce .

The noon dose = 1 /2 ounce .

The evening dose = 3/4 ounce .

Since the nurse has 1 ounce of medicine at noon ,

From the 1 ounce , 1/2 ounce will consume at noon and for evening she requires 3/4 ounce but she has left with only 1/2 ounce.So to fulfill the evening dose she needs $\frac{3}{4} - \frac{1}{2} =\frac{1}{2}$ ounce.

So she need 1/2 ounce more.
