Step-by-step explanation:
Hello there, I think your question missed key information, allow me to add in and hope it will fit the orginal one.
Let assume the side of the cube is a units
=>The surface area of the cude is:
- A =
Given that The bottom of the cake and the area where the two cakes meet is not frosted.
=> the are of a cube that is frosted in the first layer
A' = A -
= -
=5
=> the are of a cube that is frosted in the second layer
A'' = - - (the bottom and the top of it are not frosted)
= 4
=> the total the area of the cake that is frosted is:
TA = A' + A''
= 5 + 4
= 9 square units
To solve this type of question, you just need to substitute the actual side of the cube into the expression 9 . Hope it will find you well.
A five percent tip of 81.24 would be 85.30, and rounded to the nearest ten dollars, it would be 90 even.
Answer:
.75 degrees Celsius
Step-by-step explanation:
1152-1108=44 16+17=33 33divided by 44=0.75
X^2+10x+29=0
Quadratic Formula:
−b±√b^2−4(ac)/2a
Substitute the values :
a=1, b=−10, and c=29
into the quadratic formula and solve for
x.
10±√(−10)^2−4•(1•29)/ 2•1
Simplify.
Answer: x=5±2i
x * 2-8
Less than means to put it at the end, and twice the value means to mulyiply by 2.
