Sam can mow a lawn in 40 minutes. Vanessa can mow the same lawn in 60 minutes. How long does it take for both Sam and Vanessa to
xxMikexx [17]

Answer:

As a reduced fraction: \frac{120}{5} minutes, which is 24 minutes

Step-by-step explanation:

Sam's speed is 1 lawn in 40 minutes. Vanessa's speed is 1 lawn in 60 minutes. If they both work together, the total speed is:

\frac{1}{40}+\frac{1}{60}=\frac{1(3)}{40(3)}+\frac{1(2)}{60(2)}=\frac{3}{120}+\frac{2}{120}=\frac{5}{120}

Which means that the total speed would be 5 lawns in 120 minutes. To find the time it would take to mow one lawn at that speed, we need to invert that speed so we get minutes per lawn:

\frac{120}{5}=24minutes

Please please help me dayson is covering a package in the shape of a rectangular prism with wrapping paper. the package is 50 ce
olga2289 [7]

The package has a surface area of 4520cm². The area of the package is less than the area of the wrapping paper. So, dayson  can cover the package with the wrapping paper.

According to the question,

The first step is to determine the surface area of the package.

Total surface area of a cuboid = 2 (l w + w h + l h)

where:

• l = length

• w = width

• h = height

2[(50 x 20) + (50 x 18) + (20 x 18)] = 4520cm²

The second step is to convert 1 square meter to cm

1m² = 100 cm²

100 x 100 = 10,000
