Answer:
c = 15 ft
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 12^2 = c^2
c^2 = 225
c = √225
<u>c = 15 ft</u>
(7t-2) - (-3t+1) = -3*(1-3t)
First distribute:
7t-2+3t-1 = -3+9t
Now get all the terms with 't' on the same side by subtracting/adding:
7t+3t-9t = -3+2+1
Combine the terms:
1t=0
t=0
Check:
Plug in 0 for t and see if both sides of the equation come out the same:
Does (7(0)-2) - (-3(0)+1) = -3(1-3(0)) ?
(-2) - (1) = -3(1) ?
-3 = -3 ?
Yes! It works, so t=0!
Answer:
Radius is 5/π or 1.59
Step-by-step explanation:
C = 2πr
<u>Step 1: Solve for r</u>
C = 2πr
10/2 = 2πr / 2
5 / π = πr / π
5/π = r
Answer: Radius is 5/π or 1.59
Answer:
25 grams
Step-by-step explanation:
Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?
From the above question:
1 penny = 2.5 grams
10 pennies = x grams
Cross Multiply
1 × x grams = 10 pennies × 2.5 grams
x grams = 25 grams.
Hence, the weight of 10 pennies is 25 grams
