Okay first I think you might’ve highlighted incorrectly. You want to make sure the angles match with each other. Next you set up a proportion and solve. I’ll draw this all out for you. I hope this helps! :))
First, find the surface area of the bigger sides (there are 4 of them so what you get for one you will multiply by 4)
12 x 8 = 96
96 x 4 = 384
Then find the surface area of the smaller sides ( there are two small sides so multiply your answer by two)
8 x 8 = 64
64 x 2 =128
Then add both together
128 +384 = 512
Hope this helps :)
Answer:
21.50 to the nearest hundredth.
Step-by-step explanation:
This is (704.5 * 125) / (64)^2
= 88062.5 / 4096
= 21.4998
Answer:
a.) x + y - 13
Step-by-step explanation:
Trinomial = an expression with three terms
(tri- means three)
Answer choice a has three terms:
x, y, and -13
Therefore, it is the correct answer.
Answer:
Step-by-step explanation:
It's a proportion rather than an equation that you might be more accustomed to.
2/0.05 = x/ 0.95 Cross multiply
2 * 0.95 = x * 0.05 Divide by 0.05
2 * 0.95/0.05 = x
x = 38 grams of sugar should be added to the 2 grams of cinnamon.
There's another way to do it.
2/0.05 = (x + 2)/1 Cross multiply
2*1 = 0.05x + 0.1 Subtract 0.1 from both sides
1.9 = 0.05x
1.9/0.05 = x
x = 38
Which ever way you understand better is the answer. 100 / 100% is 1
