The answer is E.
First you need to find the rate. You must divide 1.8 by 100
1.8/100 = .018
Then add 1.
.018 + 1 = 1.018
Then times the starting amount with 1.018. The starting amount 750
750(1.018) = <span>763.5.
</span>As you can see, in option E that is the 2nd number.
Now we must find the next number.
You will do 750(1.018)^x
x represents the time.
763.5 was the first month.
750(1.018)^2 is the 2nd month.
750(1.018)^2 = <span>777.244 which is the 3rd number in option E</span>
Answer:
7/9 = 42/n.
7n = 378,
n = 54.
Step-by-step explanation:
Answer:
y =-14
Step-by-step explanation:
Inverse variation is of the form
xy = k where k is a constant
(-7)(-8) = k
56 = k
The equation is
xy = 56
Let x = -4
(-4)y = 56
y = 56/-4
y =-14
She worked as a carpenter for 12 hours and as a blacksmith for 18 hours.
Assuming you mean she earned $20 as a carpenter and $25 as a blacksmith per hour, with a total of 30 hours for $690,
let c represent carpenter hours and b for blacksmith hours.
20c + 25b = 690
c + b = 30
Subtract b from each side so that c = 30 - b
Plug this value into the first equation
20(30 - b) + 25b = 690
600 - 20b + 25b = 690
600 + 5b = 690
5b = 90
b = 18
To find c, plug this value of b into the other equation
c + 18 = 30
c = 12
The answer is 489,300.
Work:
We go to the tenth's place, which is 9. Since 9 is higher than 5, we need to round the hundredth's place to 3.
