180 ÷ 3 = 60 (<em>RST</em>)

60  = 7x + 4 (<em>RT</em>)

56=7x (<em>S</em>)

\bf\boxed{{x=8}}

We see the 3 step method. In this case, we're NOT going to go all the way to a 360, because this is NOT a rectangle neither a square. So, we only go 180. Anyways, 360 by 2 = 180. it's almost the same concept.

So, like we said, the 3 step method. Plug in RTS and simplify by 180. Then, we brake it down from there.

Hi there!

We know that RST is an equilateral(all 3 sides the same length) triangle, and is therefore equiangular(all 3 angles the same value).  Therefore, angle S and is equal to one-third of the triangle's angle measure.  

180/3=60

60=7x+4

56=7x

x=8

Alecsey [184]

The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of an a standard earthquake .

<h3>What is magnitude of earthquake?</h3>

Magnitude of earthquake is the measure of the size of origin of the earthquake. The magnitude of the earthquake keeps the same value for each place.

An earthquake with a magnitude of about 2. 0 or less is called a micro-earthquake and not felt usually.The intensity of an earthquake with a magnitude of 2.

Let the intensity of this earthquake is <em>n </em>times greater than the intensity of an a standard earthquake. Thus the intensity of standard earthquake can be given as,

n=10^2\\n=100

If the magnitude would be 3 then the intensity would be,

n=10^3\\n=1000

It would be 1000 times greater than the standard earthquake and so on.

Thus, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of an a standard earthquake .

ASAP HELPP PLEASE ?
Kipish [7]
<span>1. h = -16t² + vt + c
⇒ vt = 16t² + h - c
⇒ v = 16t + (h-c)/t

2. c = 5 ft
t = 3s
h = 131 ft

v = 16*3 + (131-5)/3 = 48 + 42 = 90 ft/s

when t=0, velocity is not defined. That means at t=0, there is no velocity of the t-shirt or it is 0.

What does A equal: 3(6a+12)=9
melisa1 [442]

Answer:

a = -3/2

Step-by-step explanation:

3(6a+12)=9

Divide each side by 3

3/3(6a+12)=9/3

6a+12 = 3

Subtract 12 from each side

6a+12-12 = 3-12

6a = -9

Divide by 6

6a/6 = -9/6

a = -3/2

alisha [4.7K]

Answer:

a. x^{2}  + 3y^{3}

b. 3y^{3} -6

c. 5x -3

d. -6t - 5

Step-by-step explanation:

When a number has the same variable as another, you can add or subtract them

So for the first one, you can do

5x^{2} -4x^{2} = 1x^{2}  = x^{2}

(But don't forget the 3y^{3}!)

So it is:

x^{2}  + 3y^{3}

Continue this process for the rest of them
