Answer:
12
Step-by-step explanation:
4/5 x -6 = -2
4 x -30 = -10
-120 = -10
12
We can make an equation from this.
Our intial value is 150 for parts, and he works for 52 dollars an hour.
We can define <em /><em>h</em> for hours and <em /><em>c</em> for total cost.
Therefore, we have:
c = 150 + 52h.
We can set this equal to 306 dollars, as that's the given total cost:
306 = 150 + 52h
Subtract 150 from both sides:
52h = 156
Divide both sides by 2:
h = 3
He worked 3 hours.
hope this helped!
Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
<u>How much she'll owe in 4 years</u>
P = 300
r = 0.15
n = 12
t = 4
= $544.61 (to the nearest cent)
<u>Yearly compounding interest rate</u>
<u>How much she'll owe in 4 years at yearly compounding interest</u>
= $524.70 (to the nearest cent)
There are 52 cards in a deck.
First we find the probability of drawing a 2
There are 4 cards that shows 2
Probability of drawing a 2 card fro 52 cards = 4 / 52
We know that P( not A) = 1 - P(A)
So the probability (not dealt a 2) = 1 - probability (dealt a 2)
= 1 - 4/52
= (52 - 4)/ 52 = 48/52
Now we simplify the fraction
48/ 52 = 12/13
Hence, the probability( not dealt a 2) = 12/13
