Answer:
14.4 km/h
Step-by-step explanation:
When finding km/h given m/s always multiply by 3.6
When finding m/s given km/h do the vice versa (divide by 3.6)
So.. 4km/h x 3.6 = <u>14.4 km/h </u>
Answer:
23
Step-by-step explanation:
area of a trapezoid = 1/2 × (a + b) × h
so, we have
96 = 1/2 × ((4x - 1) + (x + 3)) × 6 = (5x + 2) × 3
32 = 5x + 2
30 = 5x
x = 6
a = 4x - 1 = 4×6 - 1 = 24 - 1 = 23
9,372,000. the two in the hundreds place tells you to round down.
The total amount of different books is 16.
Take away 1 from each, representing the same book they all read.
7 - 1 = 6 , 6 - 1 = 5 , 5 - 1 = 4
Add the three together.
6 + 5 + 4 = 15
Add that one book everyone read.
15 + 1 = 16 different books.
Hope I helped you out.
