Hey! This is a very simple question, let me walk you through.
1 week = 7 days.
7 days, multiplied by 4 weeks, is 28.
This means, 28 days are in 4 weeks.
Answer:yes, the lawn can be watered completely by 4 installed sprinklers.
Step-by-step explanation:
The lawn is rectangular and its area is 32 square yards. Sprinklers are to be installed and each sprinkler waters in a circle. The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
If each sprinkler can completely water a circular area of lawn with a maximum radius of 2 yards., the the maximum area that can be watered by each sprinkler would be
Area = 3.14 × 2² = 12.56 yards²
If 4 sprinklers are completely installed, then the total area that they can water would be
12.56 × 4 = 50.24 yards²
Therefore, the lawn can be watered completely by 4 installed sprinklers.
Subtract 5 from 3 and that will be -2 which equals 9
Answer:
No, they are not equivalent.
Step-by-step explanation:
2 (37) = 74
(2*3)*7 = 6 * 7 = 42
See the calculations, explanations and results below.
1) The section to cover has tha shape of box with these dimensions:
length: 9.5 ft
width: 12 ft
depth: 4 inches
3) The volume of a box is calculated as:
V = length × witdth × depth
Since the depth is in inches convert to feet.
Conversion factor: 1 feet = 12 inches
⇒ depth = 4 in × 1 feet / 12 inches = 1/3 feet
Now, calculate the volume using feet:
V = 9,5 feet × 12 feet × 1/3 feet = 38 feet³
4) convert that to yard³ to compare with the calculations made by Rosilaine:
Conversion factor: 1 yard = 3 feet
⇒ 38 ft³ × (1 yard / 3 ft) ³ = (38 / 27) yard³ = 1.41 yard³
5) The error probably was that Rosailined used a wrong conversion factor.
Notice that 38 / 3 ≈ 12.7; so a likely mistake is that she did not cube the factor and so got about 12 yard³.
6) She might order 1.5 yard³ or 2.0 yard³ depending on the seller's rates and restrictions. With that she will have enough and will not have too much left over.
