Answer:
73
Step-by-step explanation:
to find the mean you need to add up all grades and divide if by the number of terms you added
(82 + 88 + x) ÷ 3 = 69 (since we don't know the third grade let's call it x)
170 + x = 69 × 3
x = 37
if the digits transposed the the actual grade would be 73
Step 1: Read and understand the problem statement.
You are given (time, depth) pairs of (20 s, 8 cm) and (40 s, 0 cm) and asked to write an equation that describes the relationship of depth (y) to time (x).
The rate of change is (0 cm -8 cm)/(40 s -20 s) = -8 cm/(20 s) = -2/5 cm/s. Then in point-slope form using the second point, the linear function rule is
y = (-2/5)(x -40) +0
You can expand this to
y = (-2/5)x +16
y = -0.4x +16 . . . . . . using a decimal number for the slope
_____
If the bathtubs in your "draining race" start with the same level, the one with the steepest slope (-0.5 cm/s) will win.
Answer:
74 degrees
Step-by-step explanation:
The arc degree measurement of the arc that is colored in orange is given as 254 degrees.
The remaining part is the part in green.
The green part plus the orange part should equal 360 degrees because that would make a full rotation around the circle.
.
The green arc has measurement 106 degrees.
We can find x by computing half the difference of the arcs there.
That is,



Answer:
5 years
Step-by-step explanation:
3000x.06=180 interest per year.
900/180 =5 years to earn 900 interest.
