Answer:

the Fraction is 1 $\frac{43}{100}$

Step-by-step explanation:

We divide 10 by 7 and we get 1.43 (simplest form)

then we transform it to a fraction and get 1 $\frac{43}{100}$ ( also $\frac{143}{100}$ )

GalinKa [24]

<h3>Answer: 7/4</h3>

=========================================================

How to get that answer:

The slope is the rate of change for any linear function.

Apply the slope formula for any two points on the diagonal line.

I'll use the points (-4, -3) and (0, 4)

$m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-3)}{0-(-4)}\\\\m = \frac{4+3}{0+4}\\\\m = \frac{7}{4}\\\\$

The slope is m = 7/4

This indicates that each time we go up 7 (rise), we also go to the right 4 units (run)

slope = rise/run = 7/4

rise = 7, run = 4

The fraction 7/4 converts to the decimal form 1.75

Law of Sines: $\frac{sin(A)}{a} = \frac{sin(B)}{b}$

Step-by-step explanation:

Step 1: Define

A = 50°

B = 62°

a = 4

Step 2: Solve for b

Substitute [LOS]: $\frac{sin(50)}{4} = \frac{sin(62)}{b}$
Cross-multiply: $bsin(50) = 4sin(62)$
Isolate b: $b = \frac{4sin(62)}{sin(50)}$
Evaluate: $b = 4.61042$
Round: $b \approx 4.6$
