A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches.

Which of the following is the correct scale?

1:72
1:12
1:144
5:60

Answers

Answer:

1:144

Step-by-step explanation:

if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches

Answer:

1:144 inches

Hi there!

I don’t know how to properly answer step 1, but it looks like you already have the formula written down.

For step 2, divide 120 by 3 to find how many backpacks made in one hour, or 40 backpacks per hour.

600 backpacks = 40 backpacks/1 hour * t

Step 3: This may look complicated, but i promise it is not. All we have to do here is divide 600 by 40, or 15.

t = 15, or it will take 15 hours to make 600 backpacks.

I hope this helps!

A 9-foot ladder leans against a building six feet above the ground. At what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground?​

Answers

Answer:

10

Step-by-step explanation:

You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9

The height the 15 ft building touches the building is approximately 10 ft.

The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.

The situation forms a right angle triangle.

Properties of a right angle triangle:One of it angle is equals to 90 degrees.The sides and angles can be found using trigonometric ratios.

Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.

Using trigonometric ratios,

let

∅ = angle

tan ∅ = opposite / adjacent

tan ∅ = 6 / 9 = 2 / 3

∅ = tan⁻¹ 0.6666666

∅ = 33.6900672615

Therefore, the height the 15 ft ladder touch building can be calculated as follows:

tan 33.69 = h / 15

h = 15 × 0.66666496431

h = 9.99997446476

h ≈ 10 ft.

Answers

Basically, you could set these proportions up in two ways. You could set it up as 5/35=10/x, or you could set it up as 5/10=35/x. Either way, you will get the same answer. After setting one of them up, cross multiply. You should come out with 5x=350. Divide 350/5. Here you should get the answer of 70. 70 should be the length of LN

Answer:

(a)Yellow=10

Green=38

Relative Frequency of Blue =0.32

Relative Frequency of Red =0.2

Relative Frequency of Green =0.38

(b)50 Red balls

Step-by-step explanation:

In 100 trials, the following were recorded.

Frequency of Blue Balls = 32

Frequency of Red Balls = 20

Relative Frequency of Yellow Balls =0.1

Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment

Total Number of Trials =100

Therefore:

Therefore, Number of Outcomes of Green balls=100-(32+20+10)

=100-62

Number of Outcomes of Green balls=38

(b)If the Number of Trials is Increased to 250

Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250

She should expect 50 red balls.
