Answer:

$\frac{3}{4}$

Step-by-step explanation:

Slope = change in y ÷ change in x

The line passes through (3,7) and (-1,4)

Slope = $\frac{7 - 4}{3 - -1}$ = $\frac{3}{4}$

For this case we have that by definition, the slope of a line is given by:

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

According to the data we have the following points:

$(x_ {1}, y_ {1}): (- 1,4)\\(x_ {2}, y_ {2}) :( 3,7)$

Substituting we have:

$m = \frac {7-4} {3 - (- 1)} = \frac {3} {3 + 1} = \frac {3} {4}$

Thus, the slope of the line is $\frac {3} {4}$

Answer:

$\frac {3} {4}$

En una empresa se realizan dos descuentos sucesivos : el primero del 30% y luego otro del 10% para la venta de sus artículos ¿ c

FromTheMoon [43]

If a company makes two discounts with one being made first and then another, the equivalent discount is 37%.

<h3>What was the equivalent discount?</h3>

Assume that the price of a good in the company was $10.

The initial discount of 30% takes the price to:

= 10 x ( 1 - 30%)

= $7

Then there is a 10% discount:

= 7 x (1 - 10%)

= $6.30

The equivalent discount is:

= (10 - 6.3) / 10

= 37%

Answer:

25.047 or roughly 25.

Step-by-step explanation:

I solved it wrong the first time then i double check with wolframalpha and got the correct number.

We know that the area of the tile is 18 $\sqrt{3}$ and it makes a triangle, we also know the base and height. In this case the base is 2 $\sqrt{3}^{x/12}$ and the height is also given which is $\sqrt{3}^{\frac{x}{6} }$ .

Area of triangle = $\frac{bh}{2}$ ,

substituting we will end up with 18 $\sqrt{3}$ =( 2 $\sqrt{3}^{x/12}$ * $\sqrt{3}^{\frac{x}{6} }$ ) / 2

Here is the tricky part $\sqrt{x} = x^{\frac{1}{2} }$ , i totally forgot about that lol.

Simplifying: we will get 18 $\sqrt{3}$ = $3^{\frac{x}{8} }$

Now, in order to find the x, we will need to take the log of both sides.

$log18\sqrt{3} = \frac{x}{8} log3$

Solving for x we end up getting:

$8\frac{log18\sqrt{3} }{log3}$ = x

where x = 25.047.

To be honest I deserve a nobel prize not a brainliest lol.

Good question bro, take it easy.

Peter threw the football 72 feet. How many yards did he throw the football ?

Darya [45]

1 yard = 3 feet.

Divide total feet by 3 to get yards:

72 feet / 3 = 24 yards.

Answer:

72 sides.

Step-by-step explanation:

Each exterior angle of the polygon with n sides has the measure = 5°

Formula to get the exterior angle with n sides of the polygon is,

Measure of exterior angle = $\frac{360}{n}$

By substituting the value of exterior angle in the formula,

5 = $\frac{360}{n}$

n = $\frac{360}{5}$

n = 72 sides

Therefore, the given polygon has 72 sides.
