Answer:

1/15

Step-by-step explanation:

There are a total of 10 fruits, 3 of which are apples.

The probability that the first selection is an apple is 3/10.

There are now 9 fruits remaining, 2 of which are apples. So the probability that the second fruit is an apple is 2/9.

The total probability is (3/10) (2/9) = 1/15.

Melanie's room measures 10 ft by 12 ft. Her rug covers 90 ft². Explain how to determine the percent of floor covered by the rug.

Inessa [10]

$\huge \bf༆ Answer ༄$

Here's the solution ~

Area of floor is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:10 \times 12$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:120 \: ft {}^{2}$

Area covered by rug is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:90 \: ft {}^{2}$

So, the percentage of floor covered by rug is ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{90}{120} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{3}{4} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:3 \times 25$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:75 \%$

Find the length of arc RQ. Use 3.14

Helen [10]

Answer:

The length of arc PQ is 8.1 inches.

Step-by-step explanation:

First, you have to find the angle of POQ. Given that total angles in a circle is 360°, so you have to subtract to get ∠POQ :

$73 + 150 + 65 + ∠POQ = 360$

$288 + ∠POQ = 360$

$∠POQ = 360 - 288 = 72$

Next, you have to apply length of arc formula, Arc = θ/360×2×π×r where θ represents the angle of arc and r is the radius of circle :

$arc = \frac{θ}{360} \times 2 \times \pi \times r$

$let \: θ = 72,\pi = 3.14,r = 6.48$

$arc = \frac{72}{360} \times 2 \times 3.14 \times 6.48$

$arc = 8.1 \: inches \: (near.tenth)$
