Answer:
Step-by-step explanation:
The given graph is a straight line graph. The y axis represents the number of quarts of yellow paint that is mixed. The x axis represents the number of quarts of red paint that is mixed. We would write the required equation in the slope intercept form. The slope intercept form equation of a straight line is expressed as
y = mx + c
Where
m represents slope
c represents y intercept.
Slope = (y2 - y1)/(x2 - x1)
Slope = (2 - 1)/(5 - 2.5) = 1/2.5
Slope = 0.4
The straight line cuts the y axis at y = 0
It means that c = 0
Therefore, the equation is
y = 0.4x
Answer:
42
Step-by-step explanation:
The figure is broken into different shapes so you find the area of each shape shown and add them up!
Step one: find the area of the triangle. 1/2*base*height* The base is 3 and the height is 4. it will be 6. This applies to the second triangle on the bottom as well. The total of both triangle is 12.
Step two: find the area of the rectangle.base*height. All you have to do is 10*3 which is 30.
Step three: now add up all the areas you got. 30+12. which is 42.
hope this helps :)
19 units
Use the absolute value to find the difference between the values. This ensures that no matter which way round the calculation is done the result is the same
| - 13 - 6 | = | - 19 | = 19
or
| 6 - (- 13) | = | 6 + 13 | = | 19 | = 19
Answer:
21/7
Step-by-step explanation:
Given:
Total amount spent = $14.85
Total number of flowers = 13
The cost of a lily = $1.25
The cost of a tulip = $0.90
Let x = the number of lilies bought
Let y = the number of tulips bought
Therefore
x + y = 13 (1)
1.25x + 0.9y = 14.85 (2)
From (1),
y = 13 - x (3)
Substitute (3) into (2).
1.25x + 0.9(13 - x) = 14.85
0.35x + 11.7 = 14.85
0.35x = 3.15
x = 9
y = 13 -x = 4
Answer:
9 lilies
4 tulips
