From unit conversion, it is found the following results:
6km ≈ 3.73 mi
2.5 L≈ 0.66 gal
90 lb ≈ 40.82 kg

Unit Conversion</h3>
Units of measurement are part of our daily lives. There are different units for area, length, volume, mass, and others. Because of this, it is important to know converting them.
For solving this question you need some information as:
1 km = 0.621371 mi ( unit for length and distance)
1 L = 0.2641722 gallons (unit for volume)
1 lb = 0.453592 kg (unit for mass)
Therefore,
- If 1 km = 0.621371 mi, you will have:
1 km -------- 0.621371 mi
6 km -------- x mi
x= 6* 0.621371
x=3.73 mi
Thus, 6km ≈ 3.73 mi.
- If 1 L = 0.2641722 gallons, you will have:
- 1 L-------- 0.2647122 gal
- 2.5L -------- x gal
- x= 2.5* 0.2647122
- x=0.66 gal
- Thus,
- 2.5 L≈ 0.66 gal.
- If 1 lb = 0.453592 kg, you will have:
- 1 lb-------- 0.453592 kg
- 90 lb -------- x kg
- x= 90* 0.453592
- x=40.82 kg
- Thus,
- 90 lb≈ 40.82 kg

Answer:
Step-by-step explanation:
8)Volume of cylinder = πr²h= π*3*3*10 =90π cubic inches
Volume of cone = 1/3πr²h = π*3*3*5/3= 15π cubic inches
Volume of rocket = 90π + 15π = 105π cubic inches
9) Matt made an error. radius = diameter/2 = 15/2= 7.5 cm.Instead using 7.5 in volume formula, he used diameter.
Your answer is B. Since the side line is 52, and you can rotate it to match the line, in which its not too much smaller than the line.
Answer: the answer is a
Step-by-step explanation:
Answer:
for brand A it required 41 bags and for brand B is required 56 bags
Step-by-step explanation:
The computation is shown below:
Let us assume Brand A be x
And, brand B be y
Now according to the question
The following equations are
8x + 7y = 720
4x + 6y = 500
Multiply by 2 in equation 2
8x + 7y = 720........(1)
8x + 12y = 1000..........(2)
Now subtract equation 1 from equation 2
5y = 280
y = 56 bags
And, x is
8x + 7(56) = 720
8x + 392 = 720
8x = 328
x = 41 bags
hence, for brand A it required 41 bags and for brand B is required 56 bags
