Answer:
She is going at the rate of 4.5 feet per second.
Step-by-step explanation:
Given:
The rate of walking is 90 yards per minute.
Now, to find the rate in feet per second.
1 yard = 3 foot.
1 minute = 60 seconds.
So, first we find the rate of walking per second in yard =
Therefore by dividing we get =
Now, we find the rate of walking per second in feet =
So, by multiplying we get =
Therefore, she is going at the rate of 4.5 feet per second.
I THINK
A. 6 ft²
B. draw a diagonal; each triangle would be half the area: 3 ft²
Step-by-step explanation:
Part A:
The area is the product of the length of one of the parallel sides and its distance from the other:
A = bh = (8 ft)(3/4 ft) = 6 ft²
__
Part B:
A parallelogram can be divided into two congruent triangles by either of its diagonals. Since the triangles are congruent, each will have 1/2 the area of the parallelogram. In this case, each triangle's area would be ...
(1/2)6 ft² = 3 ft²
Answer:
86.8
