9. Consider the expression
x'y'
a. Without simplifying, evaluate the expression for x = 5 and y = 7. (You may get some big numbers.)
b. Rewrite the expression using the laws of exponents.
c. Evaluate the expression you wrote in part b with the same values: x = 5 and y = 7.
d. Did you get same value for parts a and c? Why?
Answers
Answer: 270
Step-by-step explanation: a. When x = 5 and y = 7,
x'y' = 5'7'
= 10110101 (in binary)
= 181 (in decimal)
b. x'y' can be written as (2^3+1)(2^2+1)(2^1+1)(2^0+1), where ^ denotes exponentiation.
c. When x = 5 and y = 7,
x'y' = (2^3+1)(2^2+1)(2^1+1)(2^0+1)
= (8+1)(4+1)(2+1)(1+1)
= 953*2
= 270
d. No, we did not get the same value for parts a and c. The reason for this is that in part a, we evaluated x'y' using binary arithmetic, while in part c, we evaluated it using decimal arithmetic. The two methods of arithmetic yield different results.

Brittany and Will each made a triangular sign with an area of 8 square feet. The base of Brittany's triangle is half as long as the base of Will's. How do the heights of the triangles compare?
Answers
Answer:
the length of Brittany's triangular sign is 1/2 the length of Will's
Step-by-step explanation:
The height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).
How do the heights of the triangles compare?Let's assume the height of Brittany's triangle is h₁ and the height of Will's triangle is h₂.
For Brittany's triangle:
A = ¹/₂b₁h₁ = 8
For Will's triangle:
A = /₂b₂h₂ = 8
We are also given that the base of Brittany's triangle is half as long as the base of Will's triangle
b₁ = ¹/₂b₂
Now, let's find the relationship between the heights of the triangles:
From the equations above, we can see that:
h₁ = 16 / b₁
h₂ = 16 / b₂
Recall; b₁ = ¹/₂b₂
h₁ = (2 x 16) / b₂
h₂ = 16 / b₂
So, the height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

what is the surface area of a rectangular prism with a length of 38 a width of 20 and a height of 20 show work please
Answers
Answer:
The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
Given the dimensions of the rectangular prism as:
Length (l) = 38
Width (w) = 20
Height (h) = 20
Substitute the values in the formula to get:
Surface Area = 2lw + 2lh + 2wh
Surface Area = 2(38)(20) + 2(38)(20) + 2(20)(20)
Surface Area = 1520 + 1520 + 800
Surface Area = 3840 square units
Therefore, the surface area of the rectangular prism is 3840 square units.
Answer:
3840
Step-by-step explanation:
A=2(wl+hl+hw)=2·(20·38+20·38+20·20)=3840

Which statement is true about milliliters and kiloliters?
a. There are 1,000,000 milliliters in a kiloliter.
b. There are 1,000,000 kiloliters in a milliliter.
c. There are 1,000 milliliters in a kiloliter.
d. There are 1,000 milliliters in a kiloliter.
Answers
The correct statement is a. There are 1,000,000 milliliters in a kiloliter.
A kiloliter is a unit of volume equal to 1,000 liters. One liter is equal to 1,000 milliliters. Therefore, one kiloliter is equal to 1,000 x 1,000 = 1,000,000 milliliters.
