3/4 x 1/2 = <u><em>3/8</em></u>
Because you find the make the denominator to be the same, which is 4, then you keep 3/4 the same and change 1/2 to 2/4 because you times both the denominator and numerator. So it's 3/4 x 2/4 = 3/8.
4/7 x 21/40 = <u><em>3/10</em></u>
I already explained it and it's the same concept so yeah!
(Mark this as the brainliest if this helps!)
Answer:
6
Step-by-step explanation:
I use calculator to solve this so no steps
Rate = distance / time
Rate = 21 miles / 3 hours
Rate = 7 miles / hour
The answer is choice A. Hope this helps.

Answer: 180 degrees</h3>
note: it doesn't matter if its clockwise or counterclockwise when it comes to 180 degree rotations.
========================================
Explanation:
The rule for 180 degree rotations is
(x,y) ---> (-x, -y)
So the x and y coordinates flip in sign from positive to negative, or vice versa.
Point D ' (-3, 5) rotates to D ' (3, -5) following this rule
-----------------
A further detailed break down might look like this
x = -3 becomes -x = -(-3) = 3
y = 5 becomes -y = -5
(-3, 5) ----> (3, -5)
