30 because 5x6= 30. All you have to do if the fractions are already simplified, is multiply the denominators together.

Find the length of MP. round to the nearest hundredth.

lozanna [386]

Answer:

Step-by-step explanation:

Use sine:

$sine=\dfrac{opposite}{hypotenuse}$

We have:

$opposite=MP\\hypotenuse=8.7\ cm\\\alpha=20^o\\\\\sin20^o\approx0.342$

Substitute:

$\dfrac{MP}{8.7}=0.342$

$\dfrac{MP}{8.7}=\dfrac{342}{1,000}$ <em>cross multiply</em>

$1,000MP=2975.4$ <em>divide both sides by 1,000</em>

$MP=2.9754\to MP\approx2.98$

Since x=months,

Where x is the number of months times the monthly charge. Y is just the output, or end value.

I hope this helps!

Jacob walks 1.5 miles north. He turns and walks 0.8 miles west. How far is he from his starting point?

Flura [38]

Answer:

1.7 miles

Step-by-step explanation:

Given that,

Jacob walks 1.5 miles north.

He turns and walks 0.8 miles west.

We need to find how far is he from his starting point. Let he is at a distance of x miles from the starting point. It can be calculated as follows :

$x=\sqrt{1.5^2+0.8^2} \\\\x=1.7\ \text{miles}$

Hence, he is 1.7 miles from his starting point.

Answer:

Step-by-step explanation:

${ {a}^{b} }^{c} = {a}^{bc } \\ in \: this \: case \\ { ({8}^{n}) }^{3} = {8}^{3n} \\ \\ {8}^{3n} = {8}^{6 } \\ 3n = 6 \\ n = \frac{6}{3} = 2$
