Answer: 2/5
Step-by-step explanation:
Number of cans of red paint = 3
Number of cans of blue paint = 5
Number of cans of green paint = 8
Number of cans of yellow paint = 4
Total number of cans of paint = 20
The probability that Eduardo will
choose a can of red paint or a can of blue will be:
= P(red) + P(blue)
= 3/20 + 5/20
= 8/20
= 2/5
The probability is 2/5.
The slope of the line that contains the points (1 -1) and (-2 8) is -3
Step-by-step explanation:
Slope measures the steepness of a line. It is the ratio of vertical change to horizontal change. If the line increasing, the slope is positive and if the line is decreasing the slope is negative. If the line is horizontal slope is zero and if the line is vertical slope is undefined.
Equation for slope = (y2-y1)/(x2-x1)
here y2= 8
x2=-2
y1=-1
x1=1
Substituting the following,
slope = (8+1)/(-2-1)
=9/-3
=-3
hence the slope is -3
2 miles per hour
all you have to do is multiply 1/3 by 6 since she only walks 1/3 miles in 1/6 of an hour and you want to find the miles walked in a hour<span />
Answer:
if the increase in one, leads t the decrease of another, its an example of proportion
1. A property a parallelogram must have is that adjacent angles must be supplementary, they add up to 180º. We are given the values of the adjacent angles U and T. Their sum must add up to 180º. Solve for x.
<span>U + T = 180 </span>
<span>5x + 2x - 9 = 180 </span>
<span>7x - 9 = 180 </span>
<span>7x = 189 </span>
<span>x = 27 </span>
<span>Substitute this value of x for itself in angle T. </span>
<span>T = 2(27) - 9 </span>
<span>T = 54 - 9 </span>
<span>T = 45, (D) is the answer </span>
