Answer:
T=120(P+B)
Step-by-step explanation:
If a pack holds 120 tissues, then P packs will hold (P×120) tissues
This implies,
1 pack : 120 tissues
P packs : 120P tissues
Also, if a box holds 120 tissues, then B boxes will (B×120) tissues
This implies,
1 box : 120 tissues
B boxes : 120B tissues
Writing a formula in terms of T, where T is the total we obtain,
T=120P +120B
Using the idea of factorization we obtain
T=120(P+B)
Answer:
a. 281.25 grams
b. The 500 represent the original amount of aspirin.
c. 3/4 tells us what amount of the aspirin remains after every hour.
d's answer is in the picture. Just copy the line.
Step-by-step explanation:
A is the only part that needs any explanation.
Since the t represent hours, I'll subsititute t for 2.
500 * (3/4)²
<em>3/4 squared is 9/16.</em>
500 * 9/16
<em>Multiply 500 by 9 to get 4500.</em>
4500/16
<em>Simplify 4500/16 to 1125/4 (4 is canceled out.)</em>
1125/4
<em>Divide 1125 by 4 to get 281.25</em>
281.25
281.25 grams of aspirin will be in the patient body after two hours.
Answer:
3-16 divided by 1/13 = -169
Step-by-step explanation:
3-16 divided by 1/13
= (3-16) / 1/13
= -13/ 1/13
= -169
