Answer:

Hello! answer: 50

Step-by-step explanation:

This is a supplementary angle therefore it will equal a total of 180 degrees 2 × 50 = 100 100 + 13 = 113 50 + 17 = 67 113 + 67 = 180 therefore x = 50 HOPE THAT HELPS!

The jewerly store is having a sale. Necklaces that were regulaey priced at $23.50 are on dale for $18.80. What is the percentage

AveGali [126]

What we need to do is find the difference between the two numbers to find the difference in price and then figure out what the percent of 23.5 that is

23.50-18.80=4.7

now we'll set up a proportion

4.7 x
----- = -----
23.5 100

then cross multiply and divide

100×4.7=470/23.5=20

the percent of decrease is 20%

I hope I've helped!

Help mee A scout troop are hiking in a forest. Starting from their base, they walk 4.2km south followed by 7.1km west. They want

slega [8]

Answer:

They should walk on a bearing of 59.4 degrees

Step-by-step explanation:

Given

$South = 4.2km$

$West = 7.1km$

Required

The bearing back to the base

The given question is illustrated with the attached image.

To do this, we simply calculate the measure of angle a using:

$\tan(a) = \frac{Opposite}{Adjacent}$

$\tan(a) = \frac{7.1}{4,2}$

$\tan(a) = 1.6905$

Take arctan of both sides

$a = \tan^{-1}(1.6905)$

$a = 59.4^o$

PART1

Mice21 [21]

Part 1: $\frac{5x^{3} + 10x^{2} + 15x}{5x} = \frac{5x^{3}}{5x} + \frac{10x^{2}}{5x} + \frac{15x}{5x} = x^{2} + 2x + 3$
The answer is C.

Part 2: $\frac{3x^{4} + 5x^{2} + 2x}{x} = \frac{3x^{4}}{x} + \frac{5x^{2}}{x} + \frac{2x}{x} = 3x^{3} + 5x + 2$
The answer is A.
