700. To find out what number a value is ten times as much as, divide by 10.
theoretical probability is a coin will land on heads 50% of the time
50% of 100 = 50
since it only landed on heads 38 times, this was less than the theoretical probability of 50
Simple...
you have:

and

Now, the first one is easy just divide it...

Now....

needs to be converted...
Multiply the whole number*denominator...
4*8=32
Now add the numerator....
32+3=35
Now use the original denominator...

Now divide...

Thus, your answer.
Claim: The measures of
and
are equal
Answer: True
Explanation: Dilations preserve the shape of an image, so this means the angles are kept the same whether you shrink or enlarge the preimage.
====================================================
Claim: The coordinates of A and A' are the same
Answer: True
Explanation: The phrasing "dilating about point A" means that point A is the center of the universe, so to speak, in terms of this dilation operation. Point A is the fixed point that does not move while every other point does move. Because the scale factor is 2/3, which is less than 1, this means every other point comes closer to point A. So something like segment AB will get shorter.
150 divided by 20 is 7 with a remainder of 10
The quotient is 7, but the answer is 8 I'm not sure if this is what you were looking for but I hope it helped
