PLEASE HELP AND EXPLAIN WELL

Irina-Kira [14]

Answer:

Step-by-step explanation:

so basically we know in 3 years she spent 390 dollars

so 390 divided by 3 is 130

so all we need to do is find this:

130 is what percent of 2600

so the final answer is 5%

ILL GIVE BRAINLIEST HELP WITH ALGEBRA<br> Simplify the expression<br> (x+y)⁵ ÷ (x+y)²

Agata [3.3K]

Answer:

The answer is (x+y)^3

Step-by-step explanation:

using the division/subtraction law of indices

In indices division is equal to subtraction on powers

(x+y)^5 ÷ (x+y)^2

=(x+y)^5-2

=(x+y)^3

A statue is mounted on top of a 21 foot hill. From the base of the hill to where you are standing is 57feet and the statue subte

puteri [66]

Please find the attached diagram for a better understanding of the question.

As we can see from the diagram,

RQ = 21 feet = height of the hill

PQ = 57 feet = Distance between you and the base of the hill

SR= h=height of the statue

$\angle SPR=7.1^0$ =Angle subtended by the statue to where you are standing.

$\angle x$ = $\angleRPQ$ which is unknown.

Let us begin solving now. The first step is to find the angle $\angle x$ which can be found by using the following trigonometric ratio in $\Delta PQR$ :

$tan(x)=\frac{RQ}{PQ}=\frac{21}{57}$

Which gives x to be:

$x=tan^{-1} (\frac{21}{57})\approx 20.22^{0}$

Now, we know that $\angle x$ and $\angle SPR$ will get added to give us the complete angle $\angle SPQ$ in the right triangle $\Delta PQS$ .

We can again use the tan trigonometric ratio in $\Delta PQS$ to solve for the height of the statue, h.

This can be done as:

$tan(\angle SPQ)=\frac{SQ}{PQ}$

$tan(7.1^0+20.22^0)=\frac{SR+RQ}{PQ}$

$tan(27.32^0)=\frac{h+21}{57}$

$\therefore h+21=57\times tan(27.32^0)$

$h\approx8.45 feet$

Thus, the height of the statue is approximately, 8.45 feet.
