Answer.....15ft by 12ft
Explanation:
Area = Length × Width
180 = LW....make W the subject of formula
;W = 180/L
Perimeter = 2L + 2W
54 = 2L + 2(180/L)...sub W with the formula above...
then simplify the equation and obtain...
2L^2 - 27L + 180 = 0....then solve using the quadratic formula....then obtain..
;L = 15ft....after obtaining L = 15...then substitute into the W = 180/L equation...
where W = 180/15 = 12ft
there you have...Length = 15ft and Width = 12ft
Answer:
4!
Step-by-step explanation:
Given four numbers 2, 4, 6, 8.
The numbers can be arranged to form an odd number which is less than 300.
That means we have three spaces to fill this. We can try out the different combination of the numbers.
Note that the numbers should be odd. So, in the unit digit should only be 5. 2, 4, 8 would make the number even.
Also, the first digit can only be two because other numbers would make it bigger than 300.
So, 2 ___ 5 is fixed. The middle digit could be any of the four.
So, 225; 245; 255 and 285 all satisfy the conditions.
So, four numbers can be formed.
The answer is D but i could be wrong
Answer:
2167 meters squared
Step-by-step explanation:
First find the area of the square ice skating rink: 47^2 = 2209.
Then, find the area of the triangle without ice by using 1/2bh: (12/2)(7)=42.
Simply subtract the triangle's area from the squares for the final answer of 2167 meters squared.
Answer: The copy machine makes 171 copies in 4 minutes and 45 seconds.
Step-by-step explanation:
Let's dissect the question. The copy machine makes 36 copies per minute.
36 per min.
To see how many copies it makes in 4 minutes and 45 seconds, we multiply 36 * 4.75. 45 seconds is 3/4ths of a minute, or 0.75 of a minute.
It makes 171 copies in 4 minutes and 45 seconds.
