The drawing plan for an art studio shows a rectangle that is 17.2 inches by 6 inches. The scale in the plan is 2 in.: 5 ft. Find
Norma-Jean [14]

Answer:

The length is 43 feet, the width is 15 feet, and the area is 645 square feet

Step-by-step explanation:

Let us solve the question

∵ The drawing plan shows a rectangle that is 17.2 inches by 6 inches

∴ The drawing length = 17.2 inches

∴ The drawing width = 6 inches

∵ The scale in the plan is 2 in.: 5 ft

→ By using the ratio method

→  inches: feet

→  2         : 5

→  17.2     : L

→  6         : W

→ By using the cross multiplication

∵ 2 × L = 17.2 × 5

∴ 2L = 86

→ Divide both sides by 2

∴ L = 43 feet

∴ The actual length is 43 feet

→ By using the cross multiplication

∵ 2 × W = 6 × 5

∴ 2W = 30

→ Divide both sides by 2

∴ W = 15 feet

∴ The actual width is 15 feet

∵ The area of the rectangle is A = L × W

∵ L = 43 feet

∵ W = 15 feet

→ Substitute them in the rule of the area

∴ A = 43 × 15

∴ A = 645 feet²

∴ The actual area is 645 square feet

For the equation -4y =8x, what is the constant of variation?
poizon [28]
1. -4y = 8x
     y = -8/4x
     y = -2x,,,,constant of variation is -2

2. slope = 2/3, y int = 9........y = 2/3x + 9 <==

3. (1,-3)(3,1)
     slope = (1 - (-3) / (3 - 1) = (1+ 3) / 2 = 4/2 = 2 
  
     y = mx + b
    slope(m) = 2
    use either point (3,1)...x = 3 and y = 1
    now sub and find b, the y int
    1 = 2(3) + b
    1 = 6 + b
    1 - 6 = b
     -5 = b
  
    so ur equation is : y = 2x - 5 <==

Out of 75,000 voters in a constituency 65%
serious [3.7K]
<h3>Answer:</h3>

\large\boxed{35\%\,\text{did not vote;}\,48,750\,\text{voted}}

<h3>Step-by-step explanation:</h3>

In this question, we're trying to find the amount of people that did not vote and the percentage of people that didn't vote.

We know that 65% of people voted and percents are out of 100%.

We would subtract 65 form 100 to get out percentage that didn't vote.

100-65=35

35% of people didn't vote.

Now, we can solve the next question.

A total of 75,000 people voted. What we're going to have to do is find how much of 75,000 is 65%.

We would do this by multiplying 75,000 by 0.65

75,000*0.65=48,750

This means that 48,750 people voted.

<h3>I hope this helped you out.</h3><h3>Good luck on your academics.</h3><h3>Have a fantastic day!</h3>
