The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r
Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.
π*diameter=15*π
We can divide π from both sides.
diameter=15
Hope this helped!
Answer: The missing number is 5.
Step-by-step explanation:
In the table we can only have numbers between 1 and 9,
The pattern that i see is:
We have sets of 3 numbers.
"the bottom number is equal to the difference between the two first numers, if the difference is negative, change the sign, if the difference is zero, there goes a 9 (the next number to zero)"
Goin from right to left we have:
9 - 6 = 3
6 - 2 = 4
4 - 9 = - 5 (is negative, so we actually use -(-5) = 5)
4 - 4 = 0 (we can not use zero, so we use the next number, 9)
3 - 3 = 0 (same as above)
? - 1 = 4
? = 4 + 1 = 5
The missing number is 5.
130 per hour and 3 hours. 390km, 130 x 3 = 390.
Answer:
Below in bold.
Step-by-step explanation:
|-7-9x|=2
The left side is the absolute value of -7 - 9x, therefore
-7 - 9x = 2 or -7-9x = -2
-9x = 2 + 7
-9x = 9
x = -1
OR
-9x = -2 + 7
-9x = 5
x = -5/9.
Answer:
11/100
Step-by-step explanation:
I took the test on edge and got 100 percent :)
Real explanation:
It's quite easy actually. Just get all the numbers that are less than 12 and make it a fraction over the maximum number, and in this scenario it's 100. So your end result is <u>11/100</u>
Hope it helps! (can I get brainliest pls?)
