Answer:

1 yard

Step-by-step explanation:

7/14 is 1/2 while 9/14 is greater than 1/2 but a lot less than a whole. So a strong estimate would assume that it is (1 1/2)-(1/2) for the approximate difference in  their throws were

The answer would be 1 yards because 1 and 7/14 minus 9/14 is 12/14 which rounds to 1 yard

What is 2(12) 3/2 in its simpilist form
Tom [10]

Answer: 2/12 --> 1/6

3/2 --> 1 1/2

Step-by-step explanation:

2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.

3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2.  <-- this is for simplest form.

Hope this helped!

The radius of a car wheel is 12 inches. How far will the car travel and 15 revolutions of the wheel?
viktelen [127]
R = 12 inches, the radius of the wheel.

The circumference of the wheel is
2πr = 2π(12) = 24π inches.

WHen the wheel makes 15 revolutions, the car will travel 15 times the circumference, which is
15*(24π) = 360π inches = 1131 inches.

Answer: 1131 inches

Please help!!!!!!!!!!
vovikov84 [41]

Answer:

104 ft^2

Step-by-step explanation:

Before we start, one thing to notice is the 90 degrees symbol at the corners. This lets you know a rectangle has four 90 degrees angle, which will help in the next step.

First, separate the shape to become three rectangles.

After you've done that, start with the first recantgle on the left.

The edges are 8 and 5. To find the area, you must multiple 8 by 5.

8 * 5 =40

The area is 40 for the first rectangle.

Next, we do the second rectangle to the right of the first one.

oThe edges are 6 and 4. We know it is four because the full length on the rectangle on the left is 8 and below the 6 ft is the place that says 4 ft. The 6ft line cuts to rectangle in half so the other edge will be 4 ft. (Hope that made sense )

Now we find the area of the second rectangle by multiplying 6 and 4

6 *4 = 24

Now we conclude with the third rectangle. We know one edge which is 5 and the other edge will be 8 because, at the opposite end, it tells us the length is 8.

Now we multiply 8 and 5.

8 * 5 = 40.

Now, the three numbers we have found are 40, 24, and 40. Our final step is to add up these three numbers from the rectangles we made to find the area.

40 + 24 + 40 =  104

The area will be 104 ft^2

I hope this explanation helped and have a good day!

Trigonometry
Mazyrski [523]

Answer:

0.3491rad

Step-by-step explanation:

We are asked to convert 20° to radians.

#We know that 1° is equal to π/180 or 0.01745rad.

To convert any angle degrees to radians, we multiply it by π/180:

=20\times\pi/180\\\\=0.3491 \ or \ \frac{\pi}{9}rad

Hence, 20° converted to radians is 0.3491rad

What is the value of x?<br> Enter your answer in the box.<br> X=?
Marina86 [1]

Answer:

x = 32

Step-by-step explanation:

   This is an equilateral triangle. This means the angles of the triangle are all equal. Since the sum of a triangle's angles is 180°, that means each angle will be 60°.

2x-4=60\\2x=64\\x=32
