Answer:

19.6, B

Step-by-step explanation:

To solve, we need to figure out how many gallons of white paint she needs for every gallon of brown paint.

We are given this equation.

5 gallons of brown paint = 7 gallons of white paint

Divide both sides by 5.

1 gallon of brown paint = 7/5 gallons of white paint = 1.4 gallons of white paint

Now, using this, substitute 14 into the left side.

14 gallons of brown paint = 1.4 * 14 gallons of white paint

14 gallons of brown paint = 19.6 gallons of white paint

Thus, the answer is B, 19.6 gallons

Is 12000 people voted in the election how many were from 50 to 64 years
finlep [7]

Answer: 4200

Assuming that this question is based on a graph, and that this graph tells us that people 50-64 years make up 35% of all the voters, then it would mean that

35%of 12000= 35/100 * 12000= 35 * 120= 4200

So, assuming that people at age 50-64 make up 35% of the voters, then 4200 of them voted.

Greeley [361]

Answer:   maximum "safe"  Force = 415.58 N

Step-by-step explanation:

<u>Length = 1.2 m</u>

lower bound is 1.15 (because it rounds up to 1.2)

upper bound is 1.24 (because it rounds down to 1.2)

<em>Note: 1.25 would round up to 1.3</em>

<u>width = 2.5 m</u>

lower bound is 2.45 (because it rounds up to 2.5)

upper bound is 2.54 (because it rounds down to 2.5)

<em>Note: 2.55 would round up to 2.6</em>

<u>Pressure = 150 N/m²</u>

lower bound is 147.5 (because it rounds up to 150)

upper bound is 152.4 (because it rounds down to 150)

<em>Note: 152.5 would round up to 155</em>

<u>Max "safe" Force means minimum Area and minimum Pressure (lower bounds)</u>

Force = Area x Pressure

           = length x width x Pressure

           = 1.15 x 2.45 x 147.5

           = 415.58
