the area of the retangler piece of foil is 11 1/4 square inches its length is 4 1/2 inches what is the width of the foil?
2 answers:
Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
Here:
- 'w' is the width
- 'l' is the length
Given that area of the rectangular piece of foil:
Area = A = 11 1/4 square inches
= 45/4 square inches
= 11.25 square inches
Length = l = 4 1/2 inches
= 9/2 inches
= 4.5 inches
Using the Area formula
inches
Thus, the width of the foil = w = 2.5 inches

Answer:
FG=30
Step-by-step explanation:
Since we know that Point G is on the Segment FH, it doesn't really matter where G is, but we can know for certain that:
We are given that FH is 4x, GH is x, and FG is 2x+10. Substitute:
Solve for x. On the right, combine like terms:
Subtract 3x from both sides:
So, the value of x is 10.
To find the value of FG, substitute 10 into its x:
Multiply:
Add:
And we're done!
Answer: Aproximately 2,525 balloons
Step-by-step explanation:
1. Find the volume of a balloon with the formula given in the problem, where is the radius (
), then:
2. Convert the volume from m³ to lliters by multiplying it by 1,000:
3. You know that that 1 liter of helium can lift 1 gram and that Ryan weighs 5 stone and 5 pounds. So you must make the following conversions:
1 g=0.0022 lb
From 5 stones to pounds
4. Then Ryan's weigh is:
5lb+70lb=75lb
5. Then, if 1 liter of helium can lift 0.0022 lb, to lift 75 lb (which is the weight of Ryan) they need:
6. Then, to calculate the aproximated number of balloons they need to make him float (which can call ), you must divide the liters of helium needed to lift the weight of Ryan by the volume of a balloon, then the result is:
≈2,525 balloons.
