A rectangular mat has a length of 12 in. and a width of 4 in. Drawn on the mat are three circles. Each circle has a radius of 2

in. Some friends play a game throwing darts onto the mat to see who can land a dart in one of the circles. Assuming that a dart always lands on the mat, what is the probability that a dart thrown at random will land inside one of the circles? Use 3.14 to estimate Pi. Enter your answer, as a decimal rounded to the nearest hundredth, in the box. P(landing in a circle) = The figure shows three circles side by side inside a rectangle. The length of the rectangle is labeled 12 inches, and the width is labeled 4 inches. The radius of each circle is labeled 2 inches.

Area of the rectangular mat = 12 x 4 = 48 in²

Area of the 3 circles = 3( πr²) = 3(3.14 x 2²) = 37.68 in²

P(landing in a circle) = 37.68/48 = 157/200 = 0.79 (nearest hundredth)

Answer: The probability of landing in one of the circles is 0.79.

-14(3a+6)=12(6-4a)+12 and steps please
Sunny_sXe [5.5K]

Answer:

In the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28

Step-by-step explanation:

Given equation is -14(3a+6)=12(6-4a)+12

To simplify the given equation:

-14(3a+6)=12(6-4a)+12

Taking all terms to one side

-14(3a+6)-12(6-4a)-12=0

-[14(3a+6)+12(6-4a)+12]=0

Now dividing by negative sign on the above equation we get

14(3a+6)+12(6-4a)+12=0 (using distributive property)

42a+84+72-48a+12=0 ( adding the like terms )

-6a+168=0

-6a=-168

6a=168

a=\frac{168}{6}

Therefore a=28

Therefore in the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28

The perimeter of a rectangle is 60 m and its length is twice its width. find the length of the rectangle
GREYUIT [131]
Length = 2W

P= 2L + 2W
60 = 2(2W) + 2W
60= 4W +2W
60 = 6W
60/6W = 6W/6W
w = 10
Length = 2(10)
Length = 20

P= 2L + 2W
60= 2(20) + 2(10)
60= 40 +20
60 = 60

Can someone solve and explain
S_A_V [24]
The answer is F.30
Explanation: If we do guess and check, if we multiply the ratios by 10, it would be 30:40:50, which doesn’t add up to 180 degrees. if we multiply the ratios by 20, It would be 60:80:100, which also doesn’t add up to 180 degrees. How about we multiply the ratios by 15? It would be 45:60:75, which does add up to 180! The difference between x and z is 30, so the answer is F.30

Help please I don’t understand this problem
Molodets [167]

Answer:

A

Step-by-step explanation:

We know that identity:

cos^2x+sin^2x=1.

From that we have:

cos^2x=1-sin^2x.

So it is:

cos^2x-sin^x=(1-sin^2x)-sin^2x=1-2sin^2x.

And this is A).

B) is not treu because cos^2 is not sin^2x+1

C) is not true because cos^2x-sin^x=1 is false.

D) is not treu because cos^2x is not sin^2x-1
