The rectangular floor of a classroom is 40 feet in length and 32 feet in width. A scale
drawing of the floor has a length of 10 inches. What is the perimeter, in inches, of the
floor in the scale drawing?
The perimeter of the floor in the scale drawing is 36 inches.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
The scale of the drawing is 10 inches for 40 feet, which means that every inch in the drawing represents 4 feet in reality.
To find the perimeter of the floor in the scale drawing, we can add up the length of each side in the drawing, where every inch represents 4 feet.
The length of the floor is 40 feet, which is equal to 10 inches in the scale drawing (40/4=10). So, the length of the scale drawing is 10 inches.
The width of the floor is 32 feet, which is equal to 8 inches in the scale drawing (32/4=8). So, the width of the scale drawing is 8 inches.
Therefore, the perimeter of the floor in the scale drawing is:
P = 2(length + width)
= 2(10 + 8)
= 2(18)
= 36 inches
hence, the perimeter of the floor in the scale drawing is 36 inches.

Answer:
it is a right triangle
Step-by-step explanation:
Answer:
No, it's not a right triangle
Step-by-step explanation:
Use a^2 + b^2 = c^3 to find if it's a right triangle
a^2 + b^2 = c^3
(13)^2 + ([tex]\sqrt{29}[/tex] )^2 = (14)^2

find the area of triangle CDE the length of the square is 24 meters;
Answer:
288
Step-by-step explanation:
If you didnt know a triangle has the area of a square/2
so basically what im saying is the area of that square/2 equals the area of the triangle
to find the area of the square you take 24 and square it
24^2=576
finally we divide that by 2
576/2=288
so the area of the triangle is 288

(10 A person flying a kite has released
123 ft of string. The string makes an
angle of 21 degrees with the ground. How high
is the kite ?
Answer:
The kite is about 44.1 feet high.
Step-by-step explanation
Since you are trying to find the height, you would draw a triangle to diagram which sides you need to use. The 123 ft of string would be the hypotenuse of the triangle while the 21 degrees is the theta. You are trying to find the height and from the theta that would be the opposite side so you would use sine because you are using opposite and hypotenuse.
sin21=x/123
You have sin of 21 because that is the angle measure, then opposite over hypotenuse which is x/123.
You then multiply both sides by 123 to get the variable of x alone on one side.
123sin21=x
Then just plug this into your calculator and round to the nearest tenth and you get 44.1 feet.

Draw a line that connects each table to the correct graph
Answer:
For number 1, you draw a line to the middle graph
For number 2, you draw a line to the bottom graph
For number 3, you draw a line to the top graph.
Step-by-step explanation:
To figure out where the graph goes, you only need to know if the point is on the graph. For the top graph, you know that the point 2,2 is on the graph so that means one part of the graph has to be 2 and 2. The x has to equal to and the y is equal 2. Therefore, you have to draw it to the bottom graph.

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31
repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random
sample that were completed in under an hour.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317. Does this
result provide convincing evidence against the technician's claim?
Yes, it is expected that 22 of the units at most will be repaired in under an hour.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by
chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it
occurring by chance alone is not unlikely.
Answer:
D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Step-by-step explanation:
