Answer:

4.76cm

Step-by-step explanation:

Given data

circumference= 15cm

The expression for circumference is

C= 2πr

substitute and solve for r

15= 2*3.14*r

r= 15/ 2*3.14

r=15/ 6.28

r= 2.38 cm

Hence the diameter is

D= 2r

D= 2*2.38

D=4.76cm

The sum of two consecutive odd numbers is 284. Find each number please.
Vlad [161]
We can solve this by finding one of the numbers first
Let the smaller number be y. 
Since these 2 numbers are consecutive odd numbers, the larger number should be 2 more than the smaller one (y+2).

Therefore, 
y + (y+2) = 284
2y +2 = 284
shift +2 to the other side and turn it into -2
2y = 284 - 2
2y = 282
shift x2 to the other side and turn it into /2
y = 282/2
y = 141

Now we got the smaller number, which is 141, we can also find the larger number by adding 2 to it. 141+2 = 143, 
Therefore, your answer is 141 and 143

A 10 miles per hour<br> b 15 miles per hour<br> c 30 miles per hour <br> d 65 miles per hour
erik [133]
<h3>Answer: B) 15 mph</h3>

====================================================

Explanation:

The equation d = 65t means that the rate is r = 65. So Malcolm's family travels at an average rate of 65 mph. Note this is the slope of the line.

The graph has a slope of 50 because each time we go up 50, we move to the right 1. Ie, slope = rise/run = 50/1 = 50. You could use the slope formula to get the same result.

Since the graph has a slope of 50, this means Theo's family is going at an average speed of 50 mph.

Subtract the two speeds to get 65-50 = 15 mph
