Answer:
Step-by-step explanation:
<u>Ratio of corresponding sides of similar triangles are:</u>
<u>Substitute values</u>
- (9+3)/3 = 12/x
- 4 = 12/x
- x = 12/4
- x = 3
X=-8
Х/2 - x = x/4 + 6
1/2x - x = 1/4x + 6
-1/2x=1/4x+6
-2x=x+24
-2x-x=24
-3x=24
X=-8
Answer:
300,000.
Step-by-step explanation:
6x10^-3 / 2x10^-8
= 3 x (10^(-3- (-8))
= 3 x 10^5
= 300,000
Answer:
The slope is the percentage of test score per number of days absent
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to

we have
y -----> is the percentage of test score
x ----> is the number of days absent
so
That means -----> The slope is the percentage of test score per number of days absent
In this problem the slope is negative
so
If the percentage test score increases----> the number of days decreases
If the percentage test score decreases----> the number of days increases
A = $520 B = $615
A is the answer
