Answer:
≈12.96 cm
Step-by-step explanation:
To solve this exercise you must apply the Pythagorean Theorem, which is the shown below:
![a^2=b^2+c^2](https://tex.z-dn.net/?f=a%5E2%3Db%5E2%2Bc%5E2)
Where <em>a</em> is the hypotenuse and <em>b </em>and <em>c </em>are the other legs.
You know that the triangle has a leg of 11 cm and the hypotenuse is 17 cm. Therefore, you can substitute values and solve for the other leg.
Then you obtain:
b≈12.96 cm

1/5+1/5=2/5
Given :
Michaela runs to the end of her street and back in 90 s.
Her brother, Jacob, walks to the end of the street and back in 3 min.
They both run or walk for the same amount of time, but Michaela makes 5 more trips than Jacob.
To Find :
How many times did each person go to the end of the street and back.
Solution :
Let, they both walk for T seconds.
Number of rounds Michaela walk is, n₁ = T/90 .
Number of rounds Jacob walk is, n₂ =T/180 .
It is given that :
n₁ = n₂ + 5
T/90 + T/180 = 5
( T/90 + T/180 ) × 180 = 5×180
2T + T = 900
3T = 900
T = 300 s
So, n₁ = 300/90 = 3
n₂ = 1
Hence, this is the required solution.
Volume = area of cross-section x length
= 7 1/3 x 2
= 22/3 x 2/1
= 44/3
= 14 2/3
= 14.666666667
V = 44/3 (or 14 2/3, double of 7 1/3)
Hope this helps!
