Answer:
1/8
Step-by-step explanation:
Kylie's little brother ate 1/4 of 1/2 of the cake. This means he ate 1/8 of the whole cake, since 1/2 is 0.5 of the whole cake, and that means that to find the fraction of what her brother ate, you must divide 1/4 in half, which is 1/8.

Answer:
120
Step-by-step explanation:
its the same as the angle its across from
The first thing we must do for this case is to find the relationship between the variables.
We have then:
From here, we clear the value of "Y":
On the other hand we have:
From here, we clear the value of "x":
Then, replacing values we have:
On the other hand:
Finally, the perimeter is given by:
Substituting values we have:
Answer:
the perimeter of ABCD is:
44 units
7√27 + 5√48 in simple radical form
41 sqrt(3)
√27 can be written as √(3*3^2) = 3√3
√48 can be written as √(3*4^2) = 4√3
so 7√27 + 5√48 = 7*3√3 + 5*4√3 = 21√3 + 20√3 = 41√3
