Find MA:
MA = 67.2-32 = 35.2
Now set up a ratio:
35.2/67.2 = x/81.9
Cross multiply:
67.2x = 2882.88
Divide both sides by 67.2:
X = 42.9
Answer:
1. 168 cm^{2}
2. 156 in^{2}
3. 30 cm^{2}
4. 360 ft^{2}
Step-by-step explanation:
All ratio questions. We can set up proportions then cross multiply
1. \frac{8}{12} \frac{112}{x}
8x = (112 x 12)
8x = 1344
x = 168m
2.\frac{4}{8} \frac{78}{x}
4x = (78 x 8)
4x = 624
x = 156in
3. \frac{5}{2} \frac{75}{x}
5x = (75 x 2)
x = 30cm
4. \frac{8}{10} \frac{288}{x}
8x = ( 288 x 10 )
8x = 2880
x =360ft

Answer: True</h3>
Explanation:
All direct proportion equations are <u>straight lines</u> that go through the <u>origin</u>.
In this case, the constant of proportionality is 5 because of the following
- y/x = 5/1 = 5
- y/x = 10/2 = 5
- y/x = 15/3 = 5
- y/x = 35/7 = 5
- y/x = 50/10 = 5
Each x,y set of values are selected from the points in the graph. The equation of the green line is y = 5x with slope 5 and y intercept 0.
Furthermore, that slope 5 indicates that the unit rate is 5 gallons per minute.
Answer:
Wet Suit Willy found the most treasures per dive.
Step-by-step explanation:
Given:
Diver name Number of dive Number of boxes
Sam 11 33
Wet Suit Willy 18 81
Deep Diving Dan 26 104
Find:
Who found the most treasures per dive
Computation:
Sam's per dive collection = 33 / 11 = 3 boxes
Wet Suit Willy's per dive collection = 81 / 18 = 4.5 boxes
Deep Diving Dan's per dive collection = 104 / 26 = 4 boxes
Wet Suit Willy found the most treasures per dive.
