Explanations:
<u>Question 19:</u>
You had the formula set up properly like this:
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer.
<u>Question 20:
</u>
You had the formula set up correctly again, and merely used the wrong sign when
adding 32.
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F
Answer:
see below
Step-by-step explanation:
10 are blue, 30 are yellow, 20 are red, and 40 are green.
There are 100 marbles in the bag
The color that has the most marbles is green
P( green) = 40/100 = 40%
P( yellow) = 30/100 = 30%
P( red) = 20/100 = 20%
P( blue) = 10/100 = 10%
You will be more likely to pick a green marble
Answer:
a=
or 
Step-by-step explanation:
Equate the equation to zero
-9a+2=0
-5a-4a+2=0
5a(2a-1)-2(2a-1)=0
Write out the factors
(5a-2)(2a-1)=0
Then equate each factor to zero
5a-2=0 OR 2a-1=0
5a=2 OR 2a=1
a=
OR a= 
a=
or
