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:
Answer:
Step-by-step explanation:
Using substitution method.
y = 3x - 8 -------(i)
y = 4 - x -------- (ii)
Substitute y = 3x-8 in equation (ii)
3x - 8= 4 - x {Add x to both sides}
3x - 8 + x = 4 - x +x
4x - 8 = 4 {Add 8 to both sides}
4x = 4 + 8
4x = 12 {Divide both sides by 4}
x = 12/4
x = 3
Substitute x = 3 in Equation (i)
y = 3*3 - 8
y = 9 - 8
y = 1
You draw a hexagon, then draw a triangle in it. Then continue to do it until you get all the triangles that fill up the whole hexagon.
Answer:
y=3x-2 is a function because it passes the vertical line test
Answer:
volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
Step-by-step explanation:
The formula to find volume of sphere is:
Volume of sphere = 4/3 π r^3
if radius is divided by 2 i.e r/2
Volume of sphere if r/2 = 4/3 π (r/2)^3
= 4/3 π r^3/8
= (4/3 π r^3) / 8
= (Volume of sphere 1)/8
So, volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
