Rite an algebraic expression to represent "five plus the quotient of r and 14."

hichkok12 [17]

The answer is 3) 5+r/14

Let's go segment by segment:
"five plus" means addition, so we have 5 +

"the quotient of r and 14" is the division result, so sign / must be present: 14/r

Therefore "five plus the quotient of r and 14" is 5 + 14/r

Sati [7]

Answer:

$\frac{2}{7}$

Step-by-step explanation:

Given:

A car starts with a dull tank of gas

1/7 of the gas has been used around the city.

With the rest of the gas in the car, the car can travel to and from Ottawa three times.

Question asked:

What fractions of a tank of gas does each complete trip to Ottawa use?

Solution:

Fuel used around the city = $\frac{1}{7}$

Remaining fuel after driving around the city = 1 - $\frac{1}{7}$

= $\frac{7 - 1}{7} = \frac{6}{7}$

According to question:

As from the rest of the gas in the car that is $\frac{6}{7}$ , the car can complete 3 trip to Ottawa which means,

By unitary method:

The car can complete 3 trip by using = $\frac{6}{7}$ tank of gas.

The car can complete 1 trip by using = $\frac{6}{7} \div 3$

= $\frac{6}{7} \times\frac{1}{3}$

= $\frac{6}{21}$

= $\frac{2}{7}$ tank of gas

Thus, $\frac{2}{7}$ tank of gas used for each complete trip to Ottawa.

Will give brainliest!!!! Explain how solving -7y > 161 is different from solving 7y > -161.

Jlenok [28]

To solve -7y > 161, we divide both sides by -7 and we get y < -23. The inequality sign flipped because we divided both sides by a negative number.

To solve 7y > -161, we divide both sides by 7 and it leads to y > -23. The inequality sign does not flip in this case, because we are not dividing both sides by a negative number.

The similarities is that we end up with -23 on the right side, but the inequality signs are different.

A globe company currently manufactures a globe that is 16 inches in diameter. If the dimensions of the globe were reduced by hal

Veseljchak [2.6K]

Answer:

D. 267.9 in3

Step-by-step explanation:

So we know the diameter is 16 inches.

So we need to find the radius and we do that by: 16/2 = 8 then it is reduced by half: 8/2 = 4

Now we need to find the volume.

V= 4/3 times 3.14 times 4^3= 268.08

So we would need to round which would give us 267.9 in3.

Therefore the answer is the D. 267.9 in3.

I hope this helps!!!
