Answer:
y=10x-42
Step-by-step explanation:
Answer:
The x-intercept is : (22, 0)
Step-by-step explanation:
From the table values, we determine that it is a straight line as there is a constant change in x and y values.
i.e.
Any previous value of y can be obtained by subtracting 15 from the successor y value.
i.e.
60 - 15 = 45
45 - 15 = 30
so if continue, we can also determine some of the other values of y such as
30 - 15 = 15
15 - 15 = 0
Also, there is a constant change in x values. so, any previous value of x is obtained by subtracting 13 from the successor x value.
i.e.
74-13 = 61
61-13 = 48
48-13=35
35-13=22
So, from the above analysis, we determine that when the value of y = 0, the value of x = 22.
We also know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.
so, at y = 0, the value of x = 22.
Therefore, the x-intercept is : (22, 0)
Angle 1 = 180° - 40° (L.P)
Angle 1 = 140°

Answer:
$10.19
Step-by-step explanation:
We are told:
If the mean of 20 prices is $10.39
We have to find the total price
= Mean × number of prices
= 20 × $10.39
= $207.8
5 of the items with a mean of $10.99 are sampled
We would also find the total price
Mean × Number of samples
$10.99 × 5
= $54.95
what is the mean of the other 15 prices?
We find the total prices of the 15 prices
= Total 20 prices - Total of 5 prices
= $207.8 - $54.95
= $152.85
The mean of the other 15 prices
= $152.85/15
= $10.19
Answer:
the surface area should be 544 (whatever the unit is)
Step-by-step explanation:
You start by taking the rectangles on the side and finding their area.
1. (10×14)×2 ←Because there are two rectanglular sides.
2. find the area of the triangles on the side. 1/2bh = area of triangle.
(.5×8×6)×4 ← in order to find the area for all of the triangles.
3. lastly take the base of the prism and find the area then add the previously found values together.
(12×14)+(.5×8×6)×4+ (10×14)×2 = 544
