Answer:
opposite sides have the same slope, so it is a parallelogram
Step-by-step explanation:
A parallelogram has opposite sides that are parallel. Here, one pair of opposite sides consists of horizontal lines. Both have zero slope, so are parallel.
The other pair of lines each has a "rise" of 3 units for each "run" of 2 units, so the lines have a slope of 3/2. Both lines have the same slope, so are parallel.
Since opposite sides are parallel, the figure is a parallelogram.
Answer:
The radius is 1.75 cm, 1 3/4 cm, or 7/4 cm (all the same, just in different forms)
The circumference in terms of π is 7/2(π) cm, 3.5(π), or 3 1/2(π) cm (all the same, just in different forms)
The approximate circumference of the circle is 10.99 or 11 cm. (don't know if it's supposed to be rounded)
Step-by-step explanation:
Radius = 1/2 of the diameter, so 1/2 of 7/2 is 1.75, 1 3/4, or 7/4 cm.
Circumference in terms of pi means to not approximate pi. Circumference of circle is πd, so the exact circumference would be 7/2 pi cm, 3.5 pi cm, or 3 1/2 pi cm.
3.5 x 3.14 = 10.99. 10.99 cm ≈ 11 cm.

1$ is equal to 100 cents, so 43 cents out of 100 cents, or 43/100 equals 43 percent
Answer:
The expression for rate per hour is 
.
Explanation:
Given:
A machine paints 340 toy boats in 45 minutes.
To Find:
Expression equals the rate per hour?
Solution:
Finding the expression for rate per minute:
So, rate per minute expression is 
= 
Then, rate per hour expression 
So, rate per hour expression is 
= 453.334 toys per hour.
Hence, the expression for rate per hour is
