Answer: C. 5.8 inches
Step-by-step explanation:
The formula for calculating the Surface area of a cube is give as :
surface area = 6
Where a is the length of an edge
That is :
200 = 6
divide through by 6
200/6 =
that is
= 33.33333333
take the square root of both sides
a = 5.773502692
Therefore the length of an edge ≈ 5.8 inches
24:56 = 3:7 you just find the gcf of 24 and 56 then divide it by the gcf to get the simplest form
When you're solving for inequalities, you're looking for the relative size of two values meaning something is less than, greater than something else. In this case, Catie is looking to make a profit more than (>) her cost. So:
Step 1: $5 (initial fee) + $3/h of service thereafter > $26 (cost of advertising)
---- -----
Step 2: -5 -5
___________________________________________________
Step 3: + $3/h of service thereafter > $26 (cost of advertising)
------- -----
3 3
Step 4: h = 7
Therefore, in 7 hours, Catie will have enough money to breakeven. But we are looking for profit. So, in the 8th hour, Catie will have enough to make a profit.
The inequality can be written as so: 5+3h>26
You can also look at it another way:
Hour 1: $5 (initial fee) + $3/h thereafter = 8
Hour 2: +3 = 11
Hour 3: +3 = 14
Hour 4: +3 = 17
Hour 5: +3 = 20
Hour 6: +3 = 23
Hour 7: +3 = 26 (Breakeven)
Hour 8: +3 = 29 (Profit)
4x - 2y = 10
-2y = -4x + 10
y = 4/2x - 10/2
y = 2x - 5 <==
Number 7 is a because line m crosses at 2 on the y axis and number 8 is a because it goes up by one half each time
