Can someone help me in this question?The radius of the front wheel of Brian's bike is 64cm.
Brian goes for a cycle and travels 33.47km.
How many full revolutions did Brian's front wheel complete?

Answer:

-16n-41

Step-by-step explanation:

2(-n-3)-7(5+2n)

First begin by expanding the bracket.  That is, multiplyingthe brackets by 2 and -7 appropriately.

In  doing so we have,

2(-n) x 2(-3) -7(5) x -7 (+2n)

simplifying becomes:

-2n-6-35-14n

collwct like terms becomes -2n-14n-6-35

Final answer becomes Thus: -16n-41

Answer:

−16n−41

Explanation

Distribute:

=(2)(−n)+(2)(−3)+(−7)(5)+(−7)(2n)

=−2n+−6+−35+−14n

Combine Like Terms:

=−2n+−6+−35+−14n

=(−2n+−14n)+(−6+−35)

=−16n+−41

Answer:

7.351

I don't know how they have rounded; the closest answer is A

Step-by-step explanation:

The only way I know to do this is with the cos law

y^2 = x^2 + z^2 - 2*x*z cos(Y)

x = 22

z = 16

y = ?

I have serious doubts that this will make a triangle. I ran it though a calculator and it does work -- surprise for me. Substitute the givens.

y^2 = 256 + 484 - 2*10*22*cos(13)

y^2 = 740 - 704*cos(13)

y^2 = 740 - 704*0.9744

y^2 = 740 - 685.95

y^2 = 54.05                                       Take the square root of both sides

y = √54.05

y = 7.351

Answer:

7.4

Step-by-step explanation:

The information given is in from SAS.

This is a job for law of cosines.

This is the law of cosines

The angle A is opposite side a and b,c are the other sides.

So 13 degrees is opposite the y there.

Now I'm going to put 16^2+22^2-2*16*22*cos(13) in my calculator:

Now one more step. To get rid of the square, you need to square root both sides:

Sp the answer is approximately 7.4

Answer:

48

Step-by-step explanation:

6*8 = 48

I've seen you so "Will mark brainliest," many times today. Do not export people if that is what you're doing.

Answer:

Your answer is 48 sq. ft.

Step-by-step explanation:

Why? Because A= L(W) Therefore, A= 8(6)=48
