192 divided by 3.20 is 60
60 - 2 is 58
So, 58 soccer club members are going to the tournament.
Separate the shape into a triangle and a rectangle.
Find the area of the rectangle 7ft x 8ft = 56ft^2
find the height of your triangle 6ft+8ft=14ft
find the area of the triangle 1/2 (18ft x 14ft) = 126ft^2
Add the two areas together —> 56 + 126 = 182ft^2
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.
For an expression to have a rational equivalent when solved, the denominator should not be equal to 0. If the denominator is equal to zero, the expression becomes indefinite or undetermined. This is the reason for the restriction of the use of x being equal to 3 or -10.
In the given above, we can see that the expression x-3 appears both in the numerator and denominator. Hence, this can be cancelled. We are then left with the expression,
(x + 5) / (x + 10)
Therefore, the answer to this item is letter C.
(4.18 × 9) = 37.62
10^-4 × 10^-4 = 10^-8
Then since you need to move the decimal over to make it in scientific notation, you add 1 to the 10^-8 , then you get 10^-7. The problem in scientific notation is 3.726×10^-7.
