I think 2,3,4 or B,C,D would be correct.

The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h

1) 8(6) = 48/2 =24

2) 9(10 2/3) = 96/2 =48

3) 19.2(2.5) = 48

4) 16(3) = 48

Hope this is right and hope it helps. Have a good day

You have $4.10 in nickels, dimes, and quarters. If you have twice as many dimes as quarters, and five more nickels than dimes, h
lutik1710 [3]

For this case, the first thing to do is define variables.

We have then:

  • <em>x: number of nickels </em>
  • <em>y: number of dimes </em>
  • <em>z: number of quarters </em>

We write now the system of equations:

0.05x + 0.1y + 0.25z = 4.10\\y = 2z\\x = y + 5

Then rewriting the equations we have:

0.05 (2z + 5) + 0.1 (2z) + 0.25z = 4.1\\0.05 (2z + 5) + 0.1 (2z) + 0.25z = 4.1\\0.1z + 0.25 + 0.2z + 0.25z = 4.1\\0.55z = 4.1-0.25

z = \frac {3.85} {0.55}\\z = 7

Then, substituting values we have:

y = 2 (7)\\y = 14

Finally:

x = 14 + 5\\x = 19

Answer:

19 nickels

14 dimes

7 quarters

           |      \

           |         \

           |            \

100 ft.  |              \

           |         2     \

           |_________\

                    x

Use tangent to find the x.

tan(2) = \frac{100}{x}

x = \frac{100}{tan(2)}

Use a calculator to evaluate.

x = \frac{100}{tan(2)} = 2863.6253

So, the boat is 2,863.63 feet from the shore.

Angelina_Jolie [31]

The rate of 8 gallons every 25 hours means that the faucet fills \frac{8}{25} gallons every hour.

Multiply the unit rate for the number of hours you're interested in to find

\dfrac{8}{25}\cdot 13 = \dfrac{104}{25}
