[Question-2] 
<span>T(55 + 60) = 500 </span>
<span>T(115) = 500 </span>
<span>T = 500/115 </span>
<span>T = 4.3478260869565217391304347826087 hours </span>

<span>Rounding to the nearest tenth gives 4.3 </span>

<span>A is the answer </span>

Answer:

14^{-17}

Step-by-step explanation

using the rules of exponents,  it would be 14^{10}÷14^{27} so then take away 27 from 10 and get -17 meaning that the answer would be A or 14^{-17}

While in Europe, if you drive 123 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite
Leona [35]
First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
 
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.

Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.

So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.

Answer:

y=\frac{11}{20}x+6

Step-by-step explanation:

Given:

Two points are given

x = number of minutes

y = length of the lin

(x_{1},y_{1} ) ⇒ (0, 6)

(x_{2},y_{2} ) ⇒ (20, 17)

We need to find the equation that represents the relationship between x, y.

Solution:

Using slope formula to find the slope of the equation of the line.

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substitute (x_{1},y_{1} ) = (0, 6) and (x_{2},y_{2} ) = (20, 17) in above equation.

m=\frac{17-6}{20-0}\\m=\frac{11}{20}

So, slope of the line m = \frac{11}{20}

Using point slope formula.

(y-y_{1})=m(x-x_{1}) ------------(1)

Where, m = slope of the line

Substitute (x_{1},y_{1} ) ⇒ (0, 6) and m = \frac{11}{20} in equation 1.

(y-6)=\frac{11}{20} (x-0)

y-6=\frac{11}{20}x

Add 6 both side of the equation.

y-6+6=\frac{11}{20}x+6

y=\frac{11}{20}x+6

Therefore, the equation that represents the relationship between x and y is written as:

y=\frac{11}{20}x+6
