Calculate the total budget and then fill in the missing percentages (to the nearest tenth). Item $ % Contributions $175.76 Housi

Alik [6]

Answer:

Total Budget = 1,116

Contributions = 175.76/1,116 = 15.8%

Housing = 350.84/1,116 = 31.4%

Transportation = 50/1,116 = 4.5%

Clothing = 30/1,116 = 2.7%

Medical expenses = 35/1,116 = 3.1%

Food = 200/1,116 = 17.9%

Taxes = 106.40/1,116 = 9.5%

Miscellaneous = 168/1,116 = 15.1%

Step-by-step explanation:

Let's calculate the total budget and the percentages (to the nearest tenth).

Total Budget = 175.76 + 350.84 + 50 + 30 + 35 + 200 + 106.40 + 168

Total Budget = 1,116

Contributions = 175.76/1,116 = 15.8%

Housing = 350.84/1,116 = 31.4%

Transportation = 50/1,116 = 4.5%

Clothing = 30/1,116 = 2.7%

Medical expenses = 35/1,116 = 2.7%

Food = 200/1,116 = 17.9%

Taxes = 106.40/1,116 = 9.5%

Miscellaneous = 168/1,116 = 15.1%

A submarine cuts through the water at an elevation of 203 meters under the sea. The sub rises, and the elevation changes by 4.3

maw [93]

The answer is -76.1 meters.

The submarine elevation before rising is -203 meters (it is negative because it is under the sea level which has 0 elevation): d₁ = -203 m
After the first rising, it moved 64.5 m: l₁ = 4.3 · 15 = 64.5 m
After the second rising, it moved 62.4 m: l₂ = 5.2 · 12 = 62.4 m

So, to calculate the elevation of the submarine after rising (d₂), we will add (because it is not going deeper, it rises toward the elevation of 0) two movements to the elevation before rising:
d₂ = d₁ - (l₁ + l₂) = -203 + (64.5 + 62.4) = -203 + 126.9 = -203 + 126.9 = -76.1.
