An architect is creating a scale model of a building with a rectangular base. The ratio of the
building's base length to the scale model's base length is 110 in : 3 in. If the length of the base
of the scale model is 9 inches (in), what is the length of the base of the building to the nearest
foot?
Answer:

Answers

Answer: 28

Step-by-step explanation: 110in/ 3in = L/ 9in

Since we’re solving for L we see that L= 110in/ 3in x 9in = 330in.

Since there are 12 inches in 1 foot, you can determine the number of feet in the length of the building base by dividing the total number of inches by 12.

330/12 = 27.5 which rounds to 28 feet

The length of the base of the building is approximately 27.5 feet to the nearest foot.

To find the length of the base of the building, we can set up a proportion using the given ratio and the length of the base of the scale model.

Let's denote the length of the base of the building as 'x' feet.

The ratio of the building's base length to the scale model's base length is given as:

110 in : 3 in

To convert the scale model's base length to feet, we divide it by 12:

9 in ÷ 12 = 0.75 ft

Now we can set up the proportion:

110 in / 3 in = x ft / 0.75 ft

Cross-multiplying, we have:

110 in * 0.75 ft = 3 in * x ft

82.5 ft*in = 3x ft

To solve for x, we divide both sides by 3:

82.5 ft*in / 3 = x ft

27.5 ft = x ft

Therefore, the length of the base of the building is approximately 27.5 feet to the nearest foot.

It means how many floors are to be allocated in a certain area of space.

Step-by-step explanation:

Answer:


Meaning: Each floor of the buiding has a height of 15 feet.
Step-by-step explanation:
The missing figure is attached.
By definition, the ratios are used to compare two or more things or quantities.
In this case you must write the ratio of height of the building to the number of floors it has.
You can observe in the figure that the building has a height of 135 feet, and, since it has 9 floors, you can write the following ratio:

Therefore, dividing the numerator by the denominator, you get that the unit rate is:

This means that each floor of the buiding has a height of 15 feet

The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?

The measure of the larger angle is
°. what is the angle

Answers

First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x.
