Answer: 8/33

Step-by-step explanation:

So the probability of picking a purple marble is 8/12, after that there are 11 marbles left in the box

Now the probability of picking a green marble without placing the first marble back is 4/11

So the probability of doing both is 8/12 x 4/11 = 8/33

Find the measure of the largest angle in the triangle
tester [92]

Answer:

72°

Step-by-step explanation:

Find the image of the question attached

The sum of angle in a triangle is 180°

Hence:

15x+24x+21x = 180°

60x =180

x =180/60

x= 3

Get the largest angle

The largest angle out of the angles is 24x

24x =24(3)

24(3) =72°

Hence the measure of the largest angle is 72°

rugs Emporium installs carpet for $80 plus $9.50 per square yard of carpet carpets 4 U charges $120 for installation and $7.50 p
mihalych1998 [28]

The area of the carpet must be <u>greater than 20 square yards</u> for which Rugs Emporium charges more than Carpets 4U.

<u><em>Explanation</em></u>

Suppose, the number of square yards of carpet is  x

Rugs Emporium charges $80 plus $9.50 per square yard of carpet. So, the total charge for x square yards of carpet = (80+9.50x) dollar

Carpets 4U charges $120 for installation and $7.50 per square yard of carpet. So the total charge for x square yards of carpet =(120+7.50x) dollar

If the Rugs Emporium charges more than Carpets 4U , then the inequality will be.....

80+9.50x>120+7.50x\\ \\ 9.50x-7.50x>120-80 \\ \\ 2x>40\\ \\ x>20

So, the area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.
