Find the radius of the circle below. Round your answer to the nearest tenth.

Butoxors [25]

Answer:

5.8 cm

Step-by-step explanation:

Area of the shaded sector of the circle = 31.2 cm²

Angle (θ) of the minor sector = 360 - 256 = 104°

Are of sector of a circle is given as, θ/360*πr²

Therefore:

$\frac{104}{360}*3.142*r^2 = 31.2$

$0.29*3.142*r^2 = 31.2$

$0.91*r^2 = 31.2$

Divide both sides by 0.91

$\frac{0.91*r^2}{0.91} = \frac{31.2}{0.91}$

$r^2 = \frac{31.2}{0.91}$

$r^2 = 34.286$

$r = \sqrt{34.286}$

$r = 5.8$ (nearest tenth)

Solve the for the inequality

Naddika [18.5K]

Answer:

k ≥ -18

Step-by-step explanation:

$-8\leq \frac{2}{5}(k-2)\\\\-8(5)\leq (5)\frac{2}{5}(k-2)\\\\-40\leq 2(k-2)\\\\\frac{-40}{2}\leq \frac{2(k-2)}{2}\\\\-20\leq k-2\\\\-20+2\leq k-2+2\\\\-18\leq k$

Which of these expressionis is <br> equivalent to x^4-5x+3/x^2+7

bonufazy [111]

Next time, please list the possible answer choices. Without them, all I can do is to attempt this problem without having those choices as guidelines.

I must assume that your expression x^4-5x+3/x^2+7 actually meant:

5x + 3

x^4 - ---------------

x^2 + 7

and I assume that this result was one of the several possible answer choices.

debra buys a new mountain bike for 750 dollars . Sales tax is 9% . how much does Debra actually have to pay ?

Georgia [21]

Answer:

$817.50

Step-by-step explanation:

Hello Matt7151!

To find the total amount, we will first need to find how much tax.

We can express 9% as the fraction $\frac{9}{100}$ .

$\frac{9}{100}$ × 750 = 67.50

So she's paying $67.50 sales tax.

750.00

67.50

-------------------

817.50

So Debra's really paying $817.50.

Thus, the answer is $\boxed{$817.50}$$ $\boxed{817.50}$ .
