Answer:

Option B: 15 inches

Step-by-step explanation:

p=2w+2l so 12 (2*6) +2x= 42

42-12=30

30/2=15

The answer is:

15 inches

Explanation:

P = perimeter = 42

L = length = ?

W = width = 6

P rectangle = 2L + 2 W

Substitute into formula:

42 = 2L + 2 * 6

42 = 2L + 12

42 - 12 = 2L

30 = 2L

L = 30/2 = 15

L = 15 inches

I hope this helps!!!

Answer:

1/4

Step-by-step explanation:

5 orange + 5 mango = 10

P( mango ) = mango /total = 5/10 = 1/2

Replace

5 orange + 5 mango = 10

P(orange ) = orange /total = 5/10 = 1/2

P(mange, replace, orange) = 1/2 * 1/2 = 1/4

Beth does not charge a registration fee for her dog-walking service, but she charges $5 per mile that each dog is walked. Tonya’
GuDViN [60]

Answer: 10 miles.

Step-by-step explanation:

Let m the number of miles that each dog is walked.

It is given that Beth does not charge a registration fee for her dog-walking service, but she charges $5 per mile that each dog is walked.

Amount charged by Beth = 5m

Tonya’s dog-walking service charges a registration fee of $20, plus $3 per mile that each dog is walked.

Amount charged by Tonya = 20+3m

We need to find the number of miles m for which Tonya and Beth would charge the same amount.

5m=20+3m

5m-3m=20

2m=20

Divide both sides by 2.

m=10

Therefore, for 10 miles Tonya and Beth would charge the same amount.

Find the area of the shaded region
Dimas [21]

The area of the shaded region is 15.453 square units.

Step-by-step explanation:

Step 1:

The given shape consists of a rectangle and two circles.

The length of the rectangle is given as 12 cm. Both the diameters of the circles equal 12 cm. So each circle has a diameter of 6 cm and thus a radius of 3 cm.

The diameter of the circle is equal to the width of the rectangle.

So the rectangle has a length of 12 cm and a width of 6 cm. The circles have radii of 3 cm each.

Step 2:

The area of the rectangle = (l)(w) = (12)(6) = 72 square cm.

The area of each circle = \pi r^{2}  = (3.1415)(3^{2} ) = 28.2735 square cm.

The area of both circles =2(28.2735) = 56.547 square cm.

The area of the shaded region is the difference between the area of the rectangle and the area of both circles.

The area of the shaded region = 72 - 56.547 = 15.453 square units.

The area of the shaded region is 15.453 square units.
