If you laid 16 bolts that each measure 7/8 inch end to end how many feet long would the row of bolts be

2 answers:

8 0

The answer is 1 1/6 feet....this is because to find the number of inches all 16 bolts would measure, you would do:

7/8 *16=14 in.

Then to find the number of feet, you would divide 14 by 12(number of in. in a ft), and you would get 1 1/6

7/8*16
16/1*7/8
112/8
14 inches; 14 inches = 7/6 ft or about 1.2 ft

Answer and Step-by-step explanation:

As it is mentoned in the question

Polygon ABCDE rotates around point F in clockwise direction to create polygon FGHIJ

And as we can see in the figure that

So we conclude that

A = F ⇒ 117°

B = G ⇒ 90°

C = H ⇒ 127°

D = I ⇒ 90°

E = J ⇒ 117°

Therefore this is the answer and the same is to be considered

Without drawing the graph of the function y=1.2x−7, see if the graph passes through points (-10, 5)

ad-work [718]

Step-by-step explanation:

Substitute x with -10 and y with 5.

(5) = 1.2(10) - 7

5 = 12 - 7

This is obviously true, so the graph indeed passes through the point (-10, 5).

Adrian are 3 ani, iar tatăl lui are 34 de ani. Peste câți ani Adrian va fi de două ori mai tânăr decât tatăl său?

katrin [286]

Answer:

27 years

Step-by-step explanation:

Given that :

Adrian's age = 3

Father's age = 34

In how many years will Adrian be twice as young as his father?

Let the number of years = x

2(3 + x) = 34 + x

6 + 2x = 34 + x

2x - x = 34 - 6

x = 28

In Drew's town the average price for a tutor is $15 per hour, and the standard deviation is $5.25 per hour. In Drew's town, what

alukav5142 [94]

Answer:

0.659 is the probability that a tutor charges between $10 and $20 per hour.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $15 per hour

Standard Deviation, σ = $5.25 per hour

We are given that the distribution of tutoring prices is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P( tutor charges between $10 and $20 per hour)

$P(10 \leq x \leq 20)\\\\ = P(\displaystyle\frac{10 - 15}{5.25} \leq z \leq \displaystyle\frac{20-15}{5.25})\\\\ = P(-0.9523 \leq z \leq 0.9523)\\\\= P(z \leq 0.9523) - P(z < -−0.9523)\\= 0.8295 - 0.1705= 0.659$
