Answer:

Step-by-step explanation:

the radius is half of the curcumference

so you would just divide 62 by 2

62÷2

It would be around 9.87 because the formula for radius with a given for circumference is r=C/2π .
62/2 π
r=9.87.....

Answer:

$\text{D. 36.64}$

Step-by-step explanation:

The Law of Sines is given by $\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}$ and works for any triangle.

Therefore, we have the proportion:

$\frac{c}{\sin 41.5^{\circ}}=\frac{37}{\sin 42^{\circ}},\\\\c=\frac{37\sin 41.5^{\circ}}{\sin 42^{\circ}}=36.6399945706\approx \boxed{36.64}$

PLEASE HELP QUICK! I’ll give brainleist!!!

Fudgin [204]

1. set up the equation which makes these shapes equal, 1/2(2(x+1)) = 1x

2. solve, x+1=x, 1=0

3. since this is impossible, there is no solution and zero answers

12x+7<−11 AND5x−8≥4012

Arte-miy333 [17]

Answer:

No solution

Step-by-step explanation:

Given: $12x+7$ and $5x-8\geq 40$

Solve both inequality separately.

$12x+7$ Subtraction property of inequality

$12x$

$x$

and

$5x-8\geq 40$ Addition property of inequality

$5x\geq 40+8$

$5x\geq 48$

$x\geq \dfrac{48}{5}$

Hence, the solution of the compound inequality intersection of both solutions.

Please find attachment for number line solution.

Write the equation of the line that passes through the points (3,5) and (-1,1). Put

dangina [55]

Given:

A line passes through the two points (3,5) and (-1,1).

To find:

The equation of the line in fully reduced point-slope form.

Solution:

If a line passes through two points, then the point slope form of the line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The line passes through the two points (3,5) and (-1,1). So, the point slope form of the line is

$y-5=\dfrac{1-5}{-1-3}(x-3)$

$y-5=\dfrac{-4}{-4}(x-3)$

$y-5=1(x-3)$

Therefore, the point slope form of the line in fully reduced form is $y-5=1(x-3)$ , here 1 is the slope of the line.
