Isabel drove 864 miles in 12 hours.<br> At the same rate, how many miles would she drive in 7 hours?

lyudmila [28]

Answer:

504 miles

Step-by-step explanation:

Make a proportion

$\frac{864}{12}$ = $\frac{x}{7}$

7/12 is 0.5833, so multiply 864 by that to find the number of miles

864(0.5833) = 504

Alissa owns a lovely country store. She buys 6 jars of honey for $65 and then sells 5

scoundrel [369]

She will have to buy 8 jars for her to make a profit of $214

<h3>How to calculate the profit percent</h3>

If Alissa buys 6 jars of honey for $65, then;

Cost price = 6(65) = $390

If she sells 5 jars for $72, the selling price will be:

Selling price = 5(72) = $360

If she is to make a profit od $214

Profit = selling price - Cost price

214 = n(72) - 390
72n = 214 + 390
72n = 604
n = 8

Hence she will have to buy 8 jars for her to make a profit of $214

What the length of a rectangle's side (height) that is 10 cm wide and It's diagonal is 18.03 cm long?

yawa3891 [41]

Answer:

The height of a rectangle's side is 15 cm tall.

Step-by-step explanation:

You can use the pythagorean theorem to solve this.

The pythagorean theorem is:

${a}^{2} + {b}^{2} = {c}^{2}$

The hypotenuse represents the c. One the diagram, the hypotenuse represents the diagonal. The letters a and b represents the sides (just not the diagonals).

Let's plug in.

${a}^{2} + {b}^{2} = {c}^{2} \\ {a}^{2} + {10}^{2} = {18.03}^{2} \\ {a}^{2} + 100 = 325.0809 \\ \frac{ - 100 = - 100}{ {a}^{2} = \sqrt{225.0809} } \\ a = 15.00$
