Answer: 907.92 ft²

Step-by-step explanation:

1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:

$A=r^{2}\pi$

Where r is the radius of the circle.

2. You know the radius of the circle B, therefore, when you susbtitute it into the formula, you obtain that the area of the circle B is:

$A_B=(17ft)^{2}\pi=907.92ft^{2}$

Alex777 [14]

Answer:

$y\geq 3x-2$ and $y\leq \frac{1}{2} x+3$

Step-by-step explanation:

Blue:

The inequality for the blue line is

$y\geq 3x-2$

Yellow

The inequality for the yellow line is

$y\leq \frac{1}{2} x+3$

This means that the correct answer is the third option,

$y\geq 3x-2$ and $y\leq \frac{1}{2} x+3$

Can someone help me please.

The first fraction is 7/10.
The second bag has the same probability as the top so just copy the fractions into the boxes.
To calculate the probability of the same colour being chosen you follow these steps.
P(RR) = 3/10 x 4/9 = 12/90
P(GG) = 7/10 x 5/9 = 35/90
Then add the two fractions.
12/90 + 35/90 = 47/90
The last box is 47/90.
