Answer:

slope = - $\frac{4}{7}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 9) and (x₂, y₂ ) = (3, 5)

m = $\frac{5-9}{3+4}$ = $\frac{-4}{7}$ = - $\frac{4}{7}$

Step 1.

Calculate measure of angle α:

$47^o-38^o=9^o$

Step 2.

Calculate what fraction of the angle 360° is the angle α:

$\dfrac{9^o}{360^o}=\dfrac{1}{40}$

Step 3.

Calculate the circumference of the Earth (circle):

$C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi$

Step 4.

The length of arc is equal 1/40 of the circumference:

$\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi$

$\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi$

<h3>Answer: A) 628 miles</h3>

WILL GIVE BRAINLIEST IF CORRECT ANSWER!!!

Rom4ik [11]

Answer : 2√3

Given :-

A equilateral triangle with side length 4.

To Find :-

The value of x in the given figure.

As we know that in a equilateral triangle , perpendicular bisector , angle bisector and median coincide with each other .

So the perpendicular drawn in the figure will bisect the given side .
Therefore the value of each half will be 4/2 = 2 .

Now we may use Pythagoras theorem as ,

→ AB² = BC² + AC²

→ 4² = 2² + x²

→ 16 = 4 + x²

→ x² = 16-4

→ x² = 12

→ x =√12 = √{ 3 * 2²}

→ x = 2√3

Hence the required answer is 2√3 .

I hope this helps.

Answer:

The third option

Step-by-step explanation:

First, write the equation out as 700(0.25)=x and 700-x=y (y being your final answer). 700*0.25 is 175. Now, we subtract 175 from 700. 700-175 is 525. $525 is your final answer, which makes the third option correct. Hope this helps!
