Answer:
you find the area of a square by multiplying the side length by the side length. For example, the side length of a square is 10, then the area of the square would be 10 * 10= 100, the area would have been 100. A=l*l
I dont know what other shapes do you need so i would tell you how to find the area of a triangle. you find it by multiplying the base and the height and times it by 1/2. A=1/2*b*h
Answer:
a) Median: 9
b) Range: 5
c) Mode: 7
Step-by-step explanation:
The median is the number in the middle.
First, you put the numbers in order: 7, 7, 7, 8, 10, 11, 12, 12
The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.
To find the range, you minus the highest number and the lowest number, 12-7=5.
Mode is the most occurring and repetitive number, in this case, 7, because it is written 3 times.
Hope this helps!!!
Answer:
Step-by-step explanation:
2/v+1/5=3/w
(10+v)/5v=3/w
w(10+v)=15v
w=15v/(10+v)
Well just add them up
2.47 + 8.99 + 6.47 = ???
The answer is $17.93
