Answer:
a = 33ft
b= 66ft
c = 48 ft
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- a (shortest side)= a
- b (second side)=2a (twice the length of the shortest side)
- c (third side)= a+15 ( 15 feet more than the length of the shortest side)
Since:
Perimeter = a+b+c
Replacing with the values given:
147 = a+2a+(a+15)
147 = a+2a+a+15
147-15 = a+2a+a
132 = 4a
132/4 = a
33 ft= a
Substituting a =33 in the other expressions:
b=2a = 2(33) = 66 ft
c= a+15 = 33+15 = 48 ft
Answer:
D
Step-by-step explanation:
-(-4)=+4
so it is -20+4
The first one is: √ 96/8=2 √ 3
Answer:
In explanation
Step-by-step explanation:
272 for part A because say you took a test out of 850 and you got a total of 272 of them right then you would of gotten a 32%
200 for 2 because if 75% of them liked pop music and 150 teenagers what the number of teenagers surveyed then that means 200 of them were surveyed because 150 out of 200 is 75%
I don't know the last one because if you had anything there only could get a 100%(im sorry for this one it's a little confusing.
Hope this helps have a great afternoon:)
