3 can be squared twice to get the value of 9. 3x3=9
Answer:
The average number of tornado's in December is 22 and the average number of tornado's in June is 226
Step-by-step explanation:
<u><em>The complete question is</em></u>
The average number of tornado's in June is 16 less than 11 times the average number of tornado's in December. If the difference between the average number of tornado's in June and December is 204,determine the average number of tornado's in December and June.
Let
x ----> the average number of tornado's in June
y ----> the average number of tornado's in December
we know that
---> equation A
----> equation B
solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
---->
therefore
The average number of tornado's in December is 22 and the average number of tornado's in June is 226
Answer:
If The ratio of the width to
the length of a rectangle is 4:15
let width is 4x
let length is 15x
perimeter of the rectangle = 2(length + width)
= 2(15x + 4x)
= 2(19x)
=38x
If the perimeter of the rectangle is 152 meters.
152 = 38x
x= 152/38
x = 4
so,
width is 4x = 4(4) = 16m
length is 15x = 15(4) = 60m
The area of the rectangle = length. width
= 60m.16m
= 960 m^2
Step-by-step explanation:
Answer:
3 to 5 This is because if you simplify the ratio by dividing each number in the ratio by 4, therefore for every group of 5 birds 3 of them are parrots
Step-by-step explanation:
The vertex x-coordinate is in the middle between the x-intercepts
