Answer:
140
Step-by-step explanation:
Since m∠2 is 40°, then the m∠1 is also 40°. With that, ∠1 and ∠5 are supplementary, so we have 180 - 40 = 140°
Answer:
it is when it can make a mathematical statement
If you would like to solve the following system of equations, you can do this like this:
y = - 2 * x + 7
y = 1/3 * x
____________
1/3 * x = - 2 * x + 7
1/3 * x + 2 * x = 7
1/3 * x + 6/3 * x = 7
7/3 * x = 7 /*3/7
x = 7 * 3 / 7
x = 3
y = 1/3 * x = 1/3 * 3 = 1
The correct result would be: x = 3 and y = 1.
Given:
A grid with a shaded region.
To find:
The probability that a point chosen at random on the grid will lie in the shaded region.
Solution:
We have,
Total number of small boxes = 100
Number of blue boxes (shaded region) = 36
Now,
probability that a point chosen at random on the grid will lie in the shaded region is


To find the probability in percent, multiply it by 100.


Therefore, the correct option is A.
