40.2
Step-by-step explanation:
Answer:
0=0
Step-by-step explanation:
6(2x+4)=4(3x+6)
Step 1: Simplify both sides of the equation.
6(2x+4)=4(3x+6)
(6)(2x)+(6)(4)=(4)(3x)+(4)(6)(Distribute)
12x+24=12x+24
Step 2: Subtract 12x from both sides.
12x+24−12x=12x+24−12x
24=24
Step 3: Subtract 24 from both sides.
24−24=24−24
0=0
Answer:Simplifying
x = -2.125
Step-by-step explanation:Add '-10' to each side of the equation.
10 + -10 + 8x = -7 + -10
Combine like terms: 10 + -10 = 0
0 + 8x = -7 + -10
8x = -7 + -10
Combine like terms: -7 + -10 = -17
8x = -17
Divide each side by '8'.
x = -2.125
Simplifying
x = -2.125
Answer:120 degrees
Step-by-step explanation:
24 out 72 orders:.
We have total of 360° in a pichart,
So degrees that will be needed to represent 24 out of 72 on pie chart is :
Pizza= (24 / 72 ) * 360°
Pizza=8640 / 72
Pizza= 120°

Answer: 5/9</h3>
As an approximate decimal, this is 0.5556 which converts to 55.56%
======================================================
Explanation:
Let's say there are 100 households (just for the sake of simplicity). We are told that 90% of them have answering machines. So that means 90 households have answering machines. In addition, 50 households have answering machines and call waiting. Those 50 households are part of the 90 mentioned previously.
We then select a house at random. Someone tells us (or we have some kind of prior knowledge) that whichever house is selected, they have an answering machine. We can ignore the 10 households that don't have an answering machine. Out of those 90 households, 50 have both features. So 50/90 = 5/9 is the probability of getting a household with both features.
The answer would be 1/2 or 50% if we didn't have the prior knowledge of the household having an answering machine. But with this prior knowledge, the conditions change and so does the probability.
----------------
You could also compute 0.50/0.90 to get the same answer.
