Answer:

1 inch : 14.08 feet

Step-by-step explanation:

First we need to find to find the length and the width of the billboard.

The area of a rectangle is given by A= length x width

Let's call w the width of the billboard ⇒The length of the billboard will be 2.5w

Area = w (2.5w)

2,250 = 2.5w²

2250/2.5 = w²

900 = w²

30 = w

Now, to find the scale in the drawing we are going to use a ratio.

  • We have the width of the billboard, the area of the billboard and the area of the scale drawing.
  • We are going to write these values as a ratio to find the width of the scale drawing.

\frac{x}{30} =\frac{160}{2250}\\ x=\frac{(160)(30)}{2250} \\x= 2.13

Therefore, the width of the scale drawing is 2.13.

To find the scale used we can use a rule of three:

2.13 inches ------- 30 feet

1 inches --------------  x feet

x = 30/2.13 = 14.08 feet

Therefore, the scale used is 1 inch: 14.08 feet

Width = w
Length = 2.5w

Area of Rectangle: Width × Length
w (2.5w) = 2250
2.5w^2 = 2250
w^2 = 2250/2.5 = 900
w = Sq rt of 900 = 30
l = 75

Ratio of inches to ft
x/30 = 160/2250
cross multiply: 2250x = 160 × 30
2250x = 4800
x = 4800/2250 = 2.13333...

length
x/75=160/2250
2250x = 75(160)
2250x = 12,000
x= 12,000/2250
x = 5.3333...

scale is 2.13" × 5.33"

PtichkaEL [24]

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.

ANSWER

\frac{1}{3}



EXPLANATION

We want to find an odds ratio from a given probability, which is


\frac{1}{4}


We subtract the numerator 1 from the denominator 4 to obtain


4- 1= 3


The answer is the number of unfavorable outcomes. 

The Odds can then be expressed as

1 : 3


The ratio of favourable outcomes to unfavorable outcomes.


Or

\frac{1}{3}

aniked [119]

Answer:

ROA = 7.77 percent

Step-by-step explanation:

Borland, Inc., has a profit margin of 5.6 percent on sales of $13.6 million

Thus, profit = 5.6% of  $13.6 million

profit = 5.6 / 100 *  $13.6 million = $0.7616 million

Profit is same as net income

Formula for ROA (return on asset) = net income/ total asset

total asset as given = $9.8 million

Thus, ROA = $0.7616/ $9.8 = 0.0777

ROA in percentage = 0.0777*100 = 7.77

Thus, ROA is 7.77 percent .
