Answer:
x = 25 ft
Step-by-step explanation:
here we see the student standing and creating a small triangle that is equivalent to the big triangle since it has the same angles, the only difference is that its smaller, so what we have to do is make a proportion of both triangles, so since 8 ft correspond with the 40 ft they're going to be in the same part of the proportion and the other measurements, including x, on the other part, so itll be 5/8 and x/40, see how the 8 and 40 are both on the bottom? thats because they correspond, so now all you have to do is cross butterfly, so you can set up an expression on 8x= 5*40 or you can just multiply 5*40 and then divide by 8, your answer will be x= 25 ft
Answer:
Step-by-step explanation:
This only works if the room is a prism shaped, or cylinder.
Volume of a prism or cylinder is area of he base times height. So since we know the height and volume we can fand the area.
V = h*B
B = V/h
B = 400/25
B = 8
This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?
760,000 is the anwser since the number next to the 10000 place is 5. Round it up and its 760,000
Answer:
- 7040 yards
- zeros are place holders
Step-by-step explanation:
Each mile is 1760 yards, so 4 of them is ...
4 × 1760 yards = 7040 yards
__
This number is written as a decimal number in a "place value" system, so the position of the digit in the number tells its value.
In order for the 7 to indicate 7 thousand, it needs to be in the "thousands" place in the number. The 0s in the hundreds and units places are called "place holders" because they ensure the other digits appear in their proper places in the number.

If it were written in Roman Numerals, it would be 
. In this system, the letter tells its value (and "place" comes into account in XL, which means X is subtracted from L). The system of Roman Numerals has no zeros, and doesn't need them.
Since the nickels are first and there are (1.00 /.05= 20) 20 nickels in a dollar the first number is 20 then next is quarters and there is (1.00 / .25= 4) 4 quarters in a dollar so the second number is 4 so now u have to simplify if you were told to
the number 20 can be divided by 4 and the answer is 5 the number 4 is next divide by 4 and is 1 so the whole answer is 5 to 1 or 5:1<span>
