Answer:
A - y = 1200(1+.05)^30
Step-by-step explanation:
In this case, you need to calculate the future value and the formula to calculate that is:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:
FV=1200*(1+0.05)^30
According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.
Answer:
Step-by-step explanation: I'm not sue if the x's are squared so i didn't squared them but i got : 23x³-6x²
+13x-3
Answer:
A point on the line would be (-3, -7) and the slope if -3/2
Step-by-step explanation:
We can find a point on the line by choosing any value for x and putting it in to the equation. Then we can find the y value. For the purpose of this problem, we will use x = -3.
y + 1 = -3/2(x + 7)
y + 1 = -3/2(-3 + 7)
y + 1 = -3/2(4)
y + 1 = -6
y = -7
And we can find the slope simply by looking for the number outside of the parenthesis on the right side of the equal sign (-3/2)
So Jj earns a flat rate of 180 per week and an extra 15 per tablet he has sold
so what we need to do is subtract his flat rate(180) from his total(315)
315
-180
____
135 So now we know how much money Jj has earned from selling tablets. But we still need to create an equation and find out how many he has sold.
So we know he get $15 per tablet so 135÷15=9
now we know he has sold 9 tablets
Bu what is our Equation?
well, what were the steps?
TP = total pay
FR= Flat rate
C= Computer profit
PPC= price per computer
#C = number of computers
#C = TP-FR=C C÷PPC=#C
can we simplify this further?
#C = C÷PPC
lets do this:
#C= x
C= y
PPC= z
So: (X = Y÷Z)
Answer:
you would add 6 ounces of water to 9 ounces of mix
Step-by-step explanation:
to find the ratio of water to pancake mix, divide 4/4 and 6/4 to find the unit ratio of water to each 1 ounce of mix.
6/4 = 0.66...
0.66... ounces of water is used per 1 ounce of mix.
0.66... * 9 = 6
this means that 9 ounces of mix would use 6 ounces of water.
