Answer:
126mm
Step-by-step explanation:
To find the diameter of the circle = circumference divided by pi = 56.52/3.14=18mm.
There are 4 circles = 18mmx4=72mm
Add on the 3x strips = 72+(18x3) = 126mm.
Hope this helps
Answer:
they walked the same distance
Step-by-step explanation:
if you add cal's expression up which is 2(2+1)+(-4) you would have to use distributive property which means you would have to times 2 by 2 which is 4 and then times 2 by 1 and get two and then add them together and get 2 and if you do the same thing with Ari's expression you get 2.
Answer: 0.05
Step-by-step explanation:
Given : Interval for uniform distribution : [46.0 minutes, 56.0 minutes]
The probability density function will be :-

The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-

Hence, the probability that a given class period runs between 50.75 and 51.25 minutes = 0.05
B since it is negative it has negative slope.
2nd -1/2 negative
Answer:

Step-by-step explanation:
x and 3x are on a straight line together. Therefore, they are supplementary and must add to 180 degrees.
Add x and 3x, and set that equal to 180.

Combine like terms on the right side of the equation. Both x and 3x have a variable, so they can be added together.


Since we want to find x, we have to isolate x. x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.



x is equal to 45, so the correct answer is B. 45
