Answer:

You can’t add both terms because the coefficients are multiplying different variables. It’s like trying to add apples and oranges together. They are two different things. So is this situation, variables b and m are two different things. Therefore you can’t add them together. This means that you can’t simplify the expression any further. This also means that you can’t combine like terms, because the two terms are unalike.

Answer:

Step-by-step explanation:

In order to find B we must first angle C

To find angle C we use the sine rule

That's

$\frac{ |a| }{ \sin(A) } = \frac{ |c| }{ \sin(C) }$

From the question

a = 15

A = 70°

c = 14

So we have

$\frac{15}{ \sin(70) } = \frac{14}{ \sin(C) }$

$\sin(C) = \frac{14 \sin(7 0 ) }{15}$

$C = \sin^{ - 1} ( \frac{14 \sin(70) }{15} )$

C = 61.288

<h3>C = 61.3° to the nearest tenth</h3>

Since we've found C we can use it to find B.

Angles in a triangle add up to 180°

To find B add A and C and subtract it from 180°

That's

A + B + C = 180

B = 180 - A - C

B = 180 - 70 - 61.3

<h3>B = 48.7° to the nearest tenth</h3>

To find b we can use the sine rule

That's

$\frac{ |a| }{ \sin(A) } = \frac{ |a| }{ \sin(B) }$

$\frac{15}{ \sin(70) } = \frac{ |b| }{ \sin(48.7) }$

$|b| = \frac{15 \sin(48.7) }{ \sin(70) }$

b = 11.9921

<h3>b = 12.0 to the nearest tenth</h3>

Hope this helps you

A ball is released at a height of 8 inches to roll inside a half-cylinder it rolls to a height of 2 inches on the other side of

yuradex [85]

Answer:

C) 1/8 inch

Step-by-step explanation:

We are given the explicit formula

$a_n=2(\frac{1}{4})^{n-1}$ , where n is the term number.

The third climb up would be the third term; this means we replace n with 3:

$a_3=2(\frac{1}{4})^{3-1}\\\\a_3=2(\frac{1}{4})^2=2(\frac{1}{4}\times \frac{1}{4})=2(\frac{1}{16})=\frac{2}{16}=\frac{1}{8}$

A falcon flies 800,000 meters in 4 hours. Use the formula d = rt, where d represents distance, r represents rate, and t represen

pshichka [43]

Answer:

Step-by-step explanation:

d = r* t Divide both sides by t

d/t = r

r = d/ t

d = 800000

t = 4 hours

r = 800000 / 4

r = 200000 meters/hour

r = 200000 meters / hour * [ 1 km / 1000 meters]

r = 200 km / hr

I imagine you are more familiar (especially if you live anywhere but the states) with 200 km/ hour. I am very doubtful that any bird can keep that up for 4 hours. 200 km / hour is equal to about 125 miles / hour. There are few places that will allow a car to travel at that speed. You should be using km/hour because you (should) be more familiar with the units.
