To solve the problem, get first the area of the circle and the square -
Circle -> Area   = pi * r^2; r= radius
                         = 3.14 * 1.5^2m^2 (radius is 1/2 of diameter)
                         = 3.14 * 2.25m^2
                         = 7.065m^2 or 7.07m^2 when rounded-off
Square -> Area = a^2; a = side
                         = 3^2m^2
                         = 9m^2
You can now perform the subtraction process -
9.00m^2 - 7.07m^2 = 1.93m^2
Therefore, 1.93m^2 is the difference between the area of circle and square

The ratio to cranberry juice and mango juice is 3:2 they used 4 quarts of cranberry juice last week. This week mindy and her fri
IrinaVladis [17]

Answer:

The amount of mango juice needed is 8 quarts

Step-by-step explanation:

To calculate the amount of mango juice needed, we will need to know the amount used the previous week.

Cranberry juice to Mango juice is 3:2 with cranberry used being 4 quarts. Let the quarts of Mango juice used be x

This means;

3/2 = 4/x

1.5 = 4/x

1.5x = 4

x = 4/1.5 quarts

Since they are making 3 times as much punch, the amount of mango juice needed will be 4/1.5 * 3 = 4 * 2 = 8 quarts

Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate mrs s gets a loan payoff of 60 months how much interest would s
Artist 52 [7]

Answer:

\$4701.80

Step-by-step explanation:

Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate and she gets a loan payoff of 60 months,

We know that,

\text{PV of annuity}=P\left[\dfrac{1-(1+r)^{-n}}{r}\right]

Where,

PV = Present value of annuity = 25000,

r = rate of interest of each period = \dfrac{7}{12}% monthly

n = number of periods = 60 months,

Putting the values,

\Rightarrow 25000=P\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right]

\Rightarrow P=\dfrac{25000}{\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right]}

\Rightarrow P=\$495.03

Hence total amount paid is,

=495.03\times 60=\$29,701.80

Therefore interest amount is,

=29,701.80-25,000=\$4701.80
