Step 1

<u>Find the value of MN</u>

In the right triangle MNL

Applying the Pythagorean Theorem

ML^{2} =MN^{2} +NL^{2}

Solve for MN

MN^{2}=ML^{2}-NL^{2}

in this problem we have

ML=25\ units\\NL=15\ units

Substitute in the formula above

MN^{2}=25^{2}-15^{2}

MN^{2}=400

MN=20\ units

Step 2

<u>Find the value of cos (M)</u>

we know that

In the right triangle MNL

cos(M)=\frac{adjacent\ side\ angle\ M}{hypotenuse}=\frac{MN}{ML}=\frac{MN}{25}

Substitute the value of MN

cos (M)=\frac{20}{25}=\frac{4}{5}

therefore

<u>the answer is</u>

The value of cos(M) is \frac{4}{5}

PLEASE HELP!!!!!! I need help on this problem
Thepotemich [5.8K]

Answer:

185 minutes.

Step-by-step explanation:

It is possible to model an equation for this, such that

0.10x + 14.80 = 0.08x + 18.50

where x represents the number of minutes.

Then, you solve for x:

0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x =  \frac{3.70}{ 0.02}  \\ x = 185

How can properties of operations help to generate equivalent expressions that can be used in solving problems ?
svet-max [94.6K]
I’m not the best at math, but ⬇️

For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y

Solve for n 50 points <br><br> a=p(1+r/n)^rn
Andreyy89

Answer:

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

Step-by-step explanation:

a=p(1+\frac{r}{n} )^{nt}

\frac{a}{p} =(1+\frac{r}{n} )^{nt}

\sqrt[nt]{\frac{a}{p}}  =(1+\frac{r}{n} )

\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]

For each equation, find y when x=-3. Then find x when y = 2<br> 1. y = 6x + 8
crimeas [40]

<u><em>⬇ Hey, the answer is down below! :) ⬇</em></u>

<u><em>For y:</em></u> x = -3

For y it stays the same.

<u><em>For x:</em></u> y = 2

For x it stays the same too.

<u><em>For 1.):</em></u> x = \frac{1}{6}y + \frac{-4}{3}

Step-by-step explanation:

<u><em>For y there is no step-by-step explanation unfortunately.</em></u>

<u><em>For x there isn't a step-by-step explanation too unfortunately.</em></u>

<u><em>⬇ For 1.) there is a step-by-step explanation! ⬇</em></u>

For step 1 we should flip the equations.

6x + 8 = y

For step 2 we should add -8 to both sides.

6x + 8 + − 8 = y + −8

= 6x = y − 8

For step 3 we should divide both sides by 6.

\frac{6x}{6} = \frac{y - 8}{6}

= x = x = \frac{1}{6}y + \frac{-4}{3}

<u><em>In result we should have</em></u> x = \frac{1}{6}y + \frac{-4}{3} <u><em>as the answer!</em></u>
