The formula C=3.14d can be used to approximate the circumference of a circle given its diameter. Company A manufactures and sell

s a certain washer with an outside circumference of 10 centimeters. The company has decided that a washer whose actual circumference is in the interval 9.8≤C≤10.2 centimeters is acceptable. Use a compound inequality and find the corresponding interval for diameters of these washers.

Considering the equation for the circumference, the corresponding interval for diameters of these washers is:

3.121≤d≤3.248.

<h3>What is the circumference of a circle?</h3>

The circumference of a circle of diameter d is given by:

C = 3.14d.

For this problem, the circumference is between 9.8 and 10.2, hence the diameters are found as follows:

3.14d = 9.8

d = 9.8/3.14

d = 3.121.

3.14d = 10.2

d = 10.2/3.14

d = 3.248.

The intervals are:

3.121≤d≤3.248.

Mila [183]
First you do 7.9/ 1/4, that gets you 1.975. that is how much blue paint there is. Then you do 7.9-1.975= 5.925, which is how much white paint she used. So in total she used 1.975 pints of blue paint, and 5.925 pints of white paint.

Ryan buys a bag of cookies that contains 8 chocolate chip cookies, 4 peanut butter cookies, 4 sugar
Pavlova-9 [17]

Answer:

4/69 to be exact. Slightly greater than 1/18

Step-by-step explanation:

The chance of selecting the PB cookie on the first try is 4 out of 24 or 1 out of 6. There are now 23 coolies left; 8 are chocolate, so 8/23 chance. (Slightly greater than 1/3) The chance of both events happening is the product if the individual events' chances. So multiply 1/6 times 8/23 to get 8/138. That reduces to 4/ 69. If he had put that first cookie back, the multiplication would have been 1/6×1/3. A lot easier.

Describe how you regroup when you find the sum of 64+43
damaskus [11]
Here, regrouping is basically carrying. 

64+43 shown vertically would be:

  64
+43
-------
 107
4+3 is 7, so seven is in the ones place, but that's not the point.
60+40 is 100, so you regroup by carrying the one to the hundreds place.

Hope I helped!
