Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
= 23
So the age of Janet = x + 5
= 23 + 5
= 28 years
So the age of Janet's sister is 23 and Janet's age is 28
Answer:
22 qt
Step-by-step explanation:
1 gallon = 4 quart
5 × 4 + 2 = 22 qt
Answer:
100√65 yds
Step-by-step explanation:
The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.
- 700^2+400^2=c^2
- 490000+160000=c^2
- 650000=c^2
- c=√650000
√650000=√(100^2•65)=100√65
Answer:
B. 19 inches and 60 inches.
Step-by-step explanation:
Required
Select matching pairs
Represent diameter with D and Circumference with C
C is calculated as:
Where
A. D = 5m; C = 22m
Using:
15.71 does not approximates to 22m.
Hence, the pair do not match
B. D = 19 in; C = 60 in
Using:
59.698 approximates to 60.
Hence, the pair match
C. D = 33 cm; D = 80 cm.
Using:
103.686 does not approximates to 22m.
Hence, the pair do not match
From the analysis above, only option B matches the diameter with the circumference
