Answer:
175
Step-by-step explanation:
A glass and a half is 1+1/2 = 3/2 glasses.
2 1/2 glasses is 2/2 glasses more than that, or 5/2 glasses.
5/2 glasses is 5/3 times the size of 3/2 glasses, so there will be 5/3 the number of calories:
... (105 calories) × (5/3) = 175 calories
Answer:
700/1=700
Th ratio is 700 times more so we multiply by 700
700 x 0.72 = 504
504 pounds

Answer:
Elizabeth spent 17.5 hours and her sister spent 12.5 hours.
Step-by-step explanation:
Let x be the number of hours that Elizabeth shoveled and y be the number of hours that her sister shoveled.
Number of hours they shoveled = 30
So, x + y = 30 or
y = 30 - x
Jenna charged $12 per sidewalk.
So, her total earnings = 12x
Her sister charged $11 per sidewalk.
So, her total earnings = 11y.
Their total income = $347.50.
So, 12x + 11y = 347.5
Substitute y = 30 - x,
12x + 11(30 - x) = 347.5
12x + 330 - 11x = 347.5
x + 330 = 347.5
x = 347.5 - 330
x = 17.5 and
y = 30 - x = 30 - 17.5 = 12.5.
Hence, Elizabeth spent 17.5 hours and her sister spent 12.5 hours.
Answer:
310.6m^3
Step-by-step explanation:
Circumference: 18.84 m
Area: 28.26
Explanation
For circumference, use the formula *d, where d=the diameter(the radius times 2).
For area, use the formula , where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi() is Delicious(diameter) and Apple(area) ("are too")
