The directions are fairly straightforward. They are asking you to plot the two curves on a graph and find the coordinates of the point of intersection.
After 7 years, the number of birds of each species during that year will be 140.
Answer:
The difference between the largest and the smallest shares is $280
Step-by-step explanation:
Total amount to be shared = $560
Ratios of share are 2:3:9 => Total of 14 equal portions
To get one portion, $560 / 14 = $40
First share is 2, therefore $40 x 2 = $80 (smallest share)
Second share is 3, therefore $40 x 3 = $120
Third share is 9, therefore $40 x 9 = $360 (largest share)
<u>TOTAL = $560</u>
The difference between the largest and the smallest = $360 - $80
= $280
Answer:
(-1/4)(2x +5y)
Step-by-step explanation:
Multiply and divide by -1/4:
If the perimeter is 16, the side length is 4 units.
To find the area of the shaded sections, you will use the fractional part that each section represents and multiply that fraction by the total area of the square.
Area of DEA is 1/4 of 16 square Units (4 x 4).
1/4 x 16 = 4 square units
Area of EFB is 1/8 of 16 square units.
1/8 x 16 = 2 square units
4 square units +2 square units equals 6 square units.
The area of the shaded region is 6 square units.
By the way, it's pi, not pie. just wanted you to know as you may lose marks in tests for spelling (but i may be wrong)
we know circumference is pi multiplied by the diameter.
the diameter is 2x the radius
we can re-arrange the first fact to get:
diameter (or 2x radius) = circumference divided by pi.
since the circumference is 24pi we can cancel off pi from the circumference (24pi) and pi.
now we have the diameter = 24
since the diameter is 2x the radius you divide both sides by 2 and get:
radius=12cm
