iVinArrow [24]

Answer:

The answer to your question is below

Step-by-step explanation:

Let p = $\frac{cos x + siny}{\sqrt{w^{2} - z}}$

x = 36°

y = 18°

w = 29

z = 21.8

- Substitution

p = $\frac{cos 36 - sin 18}{\sqrt{29^{2} - 21.8}}$

- Simplification

p = $\frac{0.809 - 0.309}{\sqrt{841 - 21.8}}$

p = $\frac{0.5}{\sqrt{819.2}}$

p = $\frac{0.5}{28.622}$

a) Result

p = 0.017469281

b) Three significant figures

p = 0.017

c) Scientific notation

p = 1.7 x 10⁻²

a = 1.7 k = -2

6. Find QR, if area and altitude PS of ∆PQR are given<br> ar(∆PQR) = 180 cm2, PS = 15

Slav-nsk [51]

Given:

Area and altitude PS of ∆PQR are ar(∆PQR) = 180cm² and PS = 15.

To find:

The measure of side QR.

Solution:

According to the given information, PS is an altitude of ∆PQR. It means QR is the base of ∆PQR.

We know that, the area of a triangle is

$Area=\dfrac{1}{2}\times Base\times Height$

$ar(\Delta PQR)=\dfrac{1}{2}\times QR\times PS$

Substituting the given values, we get

$180=\dfrac{1}{2}\times QR\times 15$

$180\times 2=QR\times 15$

$360=QR\times 15$

Divide both sides by 15.

$\dfrac{360}{15}=QR$

$24=QR$

Therefore, the measure of side QR is 24 cm.

Kim is x years old. Jordan is 9 years older than Kim. Five times Jordan’s age is equal to 110.

soldi70 [24.7K]

J=9+x

5J=110

A) 110=5(9+x)

110=45+5x

65=5x

13=x

B) Kim is 13 years old

J=9+x

J=9+13

J=22

C) Jordan is 22 years old

There are 81 red, blue and yellow

wel

Step-by-step explanation:

Here Given

Total counters = 81

red counters are 9 more than the yellow ones.

And Yellow counter = blue counter

So let the Yellow counter be x and as blue counter and yellow counter are same then blue counter will be also x

And by the question

Red counter = 9 + x

Now

9 + x + x + x = 81

9 + 3x = 81

3x = 81 - 9

3x = 72

x = 72 / 3

Therefore x = 24

Now

Red counters = 9 + 24 = 33

Blue counters = 24

Yellow counters = 24

Hope it helped :)
