Answer: -2.3
Step-by-step explanation:
–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
–9.96 + 9.9t = 1.54 + 14.9t
-9.96 - 5t = 1.54
-5t = 11.5
t = -2.3
Answer:
There are 2 red pens in each pack
There are 3 blue pens in each pack
Step-by-step explanation:
<u> we know that</u>
270=2*3^{3} *5
180=2^{2}*3^{2}*5
<u>Find the Greatest Common Factor (GCF)</u>
The GCF is equal to------> 2*3^{2}*5=90
the greatest number of packs she can make is 90
Find the number of red pens in each pack 180/90=2 red pens
Divide the total number of red pens by the total number of packs
Find the number of blue pens in each pack 270/90=3 blue pens
Divide the total number of blue pens by the total number of packs
Answer:
318.395976 in
Step-by-step explanation:
The formula for the area of a square is A = s². s is the length of one side.
Solve the formula for area to find the length of a side.
A = s²
176 = s²
s = √176
s ≈ 13.266499 in
Count how many sides consist of the perimeter. I counted 24. Multiply 24 by the length of one side.
24 × 13.266499 = 318.395976
Answer:
