Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²
Answer:
m = -4
Step-by-step explanation:
First you have to deal with the right side of the equation since it's not spread out.
You therefore have to distribute (in order)
5×1= 5,
5×-m= -5m
And
-2×1 = -2
-2×-m = 2m
Now set it up in the order it was at first (not necessary, but helpful)
15 = 5-5m-2+2m
Add the common values...
5-2= 3
-5m+2m= -3m
Your equation should now look like this:
15= 3-3m
At this point you need to get the common values on the same side, so you would subtract 3 from both sides
15-3= 12
3-3= 0
Since you the 3 cancelled out on the right side, your equation now looks like this:
12= -3m
(Or -3m= 12)
At this point you only need to get m by itself so you would divide by -3 on both sides
-3m/-3= m (or 1m: m is understood as such)
12/-3= -4
The final answer should be
m = -4
Answer:
90
Step-by-step explanation:
There are 10 red candies, 18 green candies, 9 yellow candies, and 13 brown candies.
10 + 18 + 9 + 13 = 50.
There is a total of 50 candies. Out of the 50 candies, 18 are green.
You have to get to 250 .That means you do 
250 divided by 50 = 5.
18 x 5 = 90.
Therefore, she can expect 90 green candies
