Answer:
1233cm^2
Step-by-step explanation:
a of triangle = 1/2 bh
1/2 x 12 x 9 = 54
108 x 2 = 108
a of regtangle = l x w
25 x 15 = 375
375 x 3 = 1125
total surface area = 1125 + 108 = 1233cm^2
5x10 = 50 so that is the area. perimeter is 5+5+10+10=30
Answer:
I have gotten 216/61, but I am not sure if this is right.
Step-by-step explanation:
By using the "Keep It, Change It, Flip It" tactic, I was able to come up with an answer and simplify it.
1. Keep the original divisor.
162/3
2. Change the sign.
Division becomes multiplication.
3. The last fraction is reciprocated.
61/4 becomes 4/61.
Answer:
3/10
Step-by-step explanation:
First, let's make two variables to assign to both girls.
m = Maria's number of crayons
c = Corrine's number of crayons
Since Maria has twice as many crayons as Corrine, we know that the number of crayons Maria has is the number of Corrine's crayons multiplied by two.
Knowing this, we can make the expression <u>m = 2c</u>
