Answer:

16.5 =x

Step-by-step explanation:

Since this is a right triangle, we can us trig functions

tan theta = opp side / adjacent

tan 70 = x /6

Multiply each side by 6

6 tan 70 = x

To the nearest tenth

16.5 =x

<h2><u>Toothpaste</u></h2>

Smiles = $0.215 per ounce

Tartar Free = $0.2075 per ounce

Bright = $0.19875 per ounce

Ray Block = $0.25 per ounce

Healthy Glow = $0.3725 per ounce

I will buy Bronze Smart because it is the cheapest sunscreen here.

<h2><u>Deodorant</u></h2>

Fresh = $0.29875 per ounce

Clean Scent = $0.259 per ounce

Spring = $0.24833333333 per ounce

I will buy Spring because it costs less than the other deodorants.

Step-by-step explanation:

divide the cost by the ounces and you will get the cost per ounce

Solve.
Ray Of Light [21]

Step-by-step explanation:

let d+e=2 be equation 1

let d-e=4 be equation 2

lets make d the subject in equa 1

d = 2-e equation 3

put equation 3 in 2

2-e=4

e=2-4

e=-2

put e=-2 in equa 1

d-2=2

d=4

e is -2 and d is 4

Find each missing lengths to the nearest tenth PLEASE HELP
alisha [4.7K]

Answer:

For #1, 8.9.

Step-by-step explanation:

I can attempt to answer it, but I can't promise anything.

Alright, so, the equation for this should be A²+B²=C²

C is usually the longer side, which for you is the side that is missing.

Let's try the first one. If what I see is right, the 2 sides are 4 and 8. A is 8 and B is 4.

That means that the equation would be 8²+4²=C²

That would be 64+16=80

The equation is now 80= c²

The opposite of "to the power of 2" is a square root. So, now you're going to find the square root of 80, which is 8.9 to the nearest tenth.

So, for the first question, the answer should be 8.9

I hope this helps you solve the rest.

Directed line segment DE has endpoints D(-4,-2) and E(1,8). Point F divides DE such that DF:FE is 3:2What are the coordinates of
VMariaS [17]

The Solution.

The given points are

D(-4,-2)\text{ and E(1,8)}

The formula is

\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}

In this case,

m=3,n=2

Therefore,

\begin{gathered} (\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}) \\ =(\frac{3(1)+_{}2(-4)_{}}{3+2}_{},\frac{3(8)_{}+2(-2)_{}}{3+2}) \\  \end{gathered}=(\frac{3-8}{5},\frac{24-4}{5})=(-\frac{5}{5},\frac{20}{5})=(-1,4)

Hence, the correct answer is (-1, 4) (option 3)
