I'm guessing it's the first one because it has an exponent
Answer:
Surface area of Cube Y is 3 times greater than the surface area of cube X
Step-by-step explanation:
Surface area of a cube,A = 6s²
Where,
s = side length
Cube X has a side length of 1,
Surface area of cube, X = 6s²
= 6 * 1²
= 6 * 1
= 6
cube Y has a side length of 2
Surface area of cube, Y = 6s²
= 6 * 2²
= 6 * 4
= 24
How much greater is the surface area of cube Y than cube X?
Surface area of Cube Y is 3 times greater than the surface area of cube X
Answer:
Well, I'm not really sure what to do, but if you just need the numbers to multiply to get the latter numbers in the question they are: 10/11 (for the first question) and 81/80 for the second.
Step-by-step explanation:
For Question #1: You just multiply 5/11 by two to get the number that 1/2 has to multiply to get 5/11. And 5/11 * 2 is 10/11. So I guess the answer is 10/11...
For Question #2: The common denominator for them both is 180, and 4/9 times 81/ 80 is what 80/180 (4/9) has to multiply by to get 81/180.
I used the equation 4/9x=9/20
Multiplied the 9 and then divided by 4 to get the answer, which was 81/80.
***I also noticed, that 1/2 is 1/22 away from 5/11, and 4/9 is 1/180 away from 9/20.
Hope this helps!
Answer:
slope = - 
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m = 
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m = 
= 
= -
