Answer:

(3) 0.25q+0.10(72-q)=14.70

Step-by-step explanation:

Let d represent number of dimes and q represent number of quarters.

We have been given that Byron has 72 coins in his piggy bank. We can represent this information in an equation as:

q+d=72...(1)

We are also told that the value of all coins is $14.70.

Value of d dimes: 0.10d.

Value of q quarters: 0.25q.

0.25q+0.10d=14.70...(2)

From equation (1), we will get:

d=72-q

Substitute this value in equation (2):

0.25q+0.10(72-q)=14.70

Therefore, the equation 0.25q+0.10(72-q)=14.70 can be used to determine q, the number of quarters.

Find the area round to two decimal places as needed
Mademuasel [1]

To find the area of an obtuse triangle you have to multiply the base of the triangle by the vertical height and divide the result by 2 following the formula:

A=\frac{b\cdot h}{2}

The base of the triangle is b= 7 miles and the height is h= 8 miles, using these lengths calculate the area as follows:

\begin{gathered} A=\frac{7\cdot8}{2} \\ A=\frac{56}{2} \\ A=28mi^2 \end{gathered}

The area of the triangle is 28 square miles.
