An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has length
and width
The actual tiles have length
and width
. What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways to find each ratio.
The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches
So the answer can be solved like this:
1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)
or
1/3in to 3in which is also 9:1 (blueprint size to actual size)
Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.

The scatter plot shows a hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the hiker's elevation is y=7.52x+649, where x represents the number of minutes and y represents the hiker's elevation in feet. Use the equation of the trend line to estimate the hiker's elevation after 170 minutes.
After 170 minutes, the hiker's elevation will be about _____ feet above sea level.
Answer:

What is the perimeter of quadrilateral A' B' C' D'?
Explanation:
Quadrilateral A B C D is translated 2 units to the left and 5 units down to create quadrilateral A' B' C' D'.
Answer:
14.2 Units
Step-by-step explanation:
The second shape is given to confuse you and is not actually necessary.
To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.
1.4units + 2.2units + 4.5units +6.1units = 14.2 units.

Kevin is making a picture frame. He has a piece of trim that is 4 feet long.How many 14−inch-long pieces can Kevin cut from the trim?How much of a foot will he have left over?
First, convert 4 feet into inches - 48 inches. Then, divide 48 by 14 to get 3.43, so he can have 3 14-inch long pieces. To get the left over out of a foot, take 14 x 3 to get 42, then subtract 42 from your original 48 inches to get 6 inches left, which is half of a foot.
Answer:
3 pieces and 1/2 of a foot
Step-by-step explanation:
1. 4 feet converts to 48 inches. (4 X 12)
2. 48 inches divided by 14 can make three pieces
14+14+14=42 inches.
3. You will have 6 inches left over, and 6/12 is half of a foot :)
Which property is illustrated by the statement 3 + 0 = 3?
Answer: Identity Property
Step-by-step explanation: The identity property holds true for addition.
The statement 3 + 0 = 3 represents the identity property of addition.
The identity property of addition says that when we add 0
to any number, the sum is equal to the original number.
In general terms, we can write the identity property of addition
as a + 0 = a where a is a variable that represents any number.

-- i am not sure about this, but i tried.
f (x) = 2x + 5
Clearing x we have:
2x = y - 5
x = (y-5) / 2
Rewriting:
f (x) ^ - 1 = (x-5) / 2
Evaluating x = 8:
f (8) ^ - 1 = (8-5) / 2
f (8) ^ - 1 = 3/2
Answer:
f (8) ^ - 1 = 3/2

Substitue 15 into the x value and complete the equation.
This is because 2,280 is the original distance. 15 would be the hours and 60 would be how many miles per hour. So we multiply 15 and 60 and get 900, this is how many total miles they have driven. But when we subtract that number from 2,280, and we get 1,380, this is how many miles they have left.
Answer:
The distance is driven 1380 in 15 hours.
Step-by-step explanation:
Find:
D when t=15
D(15) = 2280 - 60(15)
D(15) = 2280 - 900
D(15) = 1380
D = 1380/15
The distance is driven 1380 in 15 hours.
