$36.8 because if you do 40 times .08 you get 3.2, after that you do 40-3.2 and you get 3.8. Hope this helps.

A mechanic had a bolt with a diameter of 2/9 inch. Will the bolt fit into a hole with a diameter of 0.2 inch.
Naddik [55]

Answer:

No, the bolt won't fit into the hole

Step-by-step explanation:

We need to convert the diameter of the bolt into decimal by dividing:

2/9 = 0.222...

The hole has diameter of 0.2

<em>Hence, 0.222 is larger than 0.2, so the bolt won't fit.</em>

5. Write down the nth term of each of the following G.Ps
yawa3891 [41]

Answer:

1i) nth term = 12(-b/4)^(n-1)

ii) nth term = 3(-1/9)^(n-1)

2i) Sixth term= (-3b^5)/256

ii) Eight term = -1/1594323

Question:

The complete question as found on brainly (question-10746111):

Write down the nth term of each of the following G.Ps whose first two terms are given as follows. Also find the term stated besides each G.P.

i) 12,-3b,......sixth term

ii) 3,-1/3,..........;8th term?

Step-by-step explanation:

1) To solve terms involving Geometric progressions (GPs), we would first state the variables that are to be incorporated in the formula.

i) 12,-3b,......;sixth term

1st term = a= 12

r = common ratio = 2nd term /1st term

r = -3b/12 = -b/4

Then we would find the nth term

See attachment for details

ii) 3,-1/3,..........;8th term

1st term = a= 3

r = common ratio = 2nd term /1st term

r = (-⅓)/3 = (-⅓)(⅓) = -1/9

Then we would find the nth term

See attachment for details

2) we are to determine the sixth term in (i) and eight term in (ii)

See attachment for details

Sixth term= (-3b^5)/256

Eight term = -1/1594323

Find the cosine of R.
JulijaS [17]

Answer:

cos(R) = \frac{\sqrt{15}}{5}

Step-by-step explanation:

To find the cosine of <R, apply the following trigonometric ratio formula:

cos(R) = \frac{adjacent}{hypotenuse}

Adjacent = 3

Hypotenuse = √15

Plug in the values into the formula

cos(R) = \frac{3}{\sqrt{15}}

Multiply the numerator and denominator by √15 to rationalize.

cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}}

cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2}

cos(R) = \frac{3\sqrt{15}}{15}

cos(R) = \frac{\sqrt{15}}{5}
