Step-by-step explanation:

This is a common knowledge of equivalent fractions.

Multiplying both the numerator and denominator of a fraction by the same quantity does not change the value of the fraction.

Not only multiplication, but division also works. What ever operation performed on the numerator must also be performed on the denominator.

1/2 = 2/4 = 4/8 = 16/32

Gabriel is driving 80 kilometers in one hour. How many kilometers does he drive in 1.5 hours

gogolik [260]

Answer:

He drove 120 km

Step-by-step explanation:

We know that 1 hour of driving is equal to 80 km. We need to find out for 1.5 km. First, we need to know how much km for 1/2 of an hour. Which will be 40, because 80/2=40. Then we add up the 40 to the 80, and we get 120 km in total.

<u>We know that,</u>

slope = $\rm{\frac{(y2 - y1)}{(x2 - x1)} }$

Let (0,1)=(x 1 ,y 1 ) and (1,2)=(x 2,y 2 )

So,

Slope of line = $\frac{(2 - 1)}{(1 - 0)} = 1$

Now,

The required line equaqtion is given by,

==> y−y 1 = m(x-x1)

==> y−1=1(x−0)

==> y−1=x

==> y=x+1

Twenty years ago a small town in Texas had a population of 10,000. The population has increased 8% each year since then. Predict

fenix001 [56]

Answer: After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.

Step-by-step explanation:

Since we have given that

Initial population 20 years ago = 10,000

Rate of growth = 8%

Number of years = 10+20 = 30 years

According to question, we will use "Compound interest":

$Amount=P(1+\frac{r}{100})^n\\\\Amount=10000(1+\frac{8}{100})^{30}\\\\Amount=10000(1+0.08)^{30}\\\\Amount=10000(1.08)^{30}\\\\Amount=100626.57$

Hence, After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.

(A) Find the slope of the line that passes through the given points.

Mariulka [41]

$(\stackrel{x_1}{-3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{4}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{(-3)}}} \implies \cfrac{0}{6 +3}\implies 0$

hmmm a line with a slope of 0 is a horizontal one, and it has no slope-intercept form.

Check the picture below.
