Answer:
15 sheep
Step-by-step explanation:
1 leg = 1 foot
1 head = 1 animal
Suppose all the animals are chickens:
50 × 2 = 100
130 - 100 = 30
4 - 2 = 2
30 ÷ 2 = 15
Hence, there are 15 sheep.
Answer:
x=-3
Step-by-step explanation:
4x+6=8x+18
We simplify the equation to the form, which is simple to understand
4x+6=8x+18
We move all terms containing x to the left and all other terms to the right.
+4x-8x=+18-6
We simplify left and right side of the equation.
-4x=+12
We divide both sides of the equation by -4 to get x.
x=-3
Answer:
40
Step-by-step explanation:
f(4) = 3(4²) - 2(4)
= 3(16) - 8
= 48 - 8
= 40
when x=4, f(x) = 40
Diameter=16mm, so the radius is 8. The formula for volume of a cylinder is the area of the base times height, or v=πr²h.
Substituting the values in, we get π(8²)(5.7), which gives us roughly 1146mm^3.
It would be 40,000 if you rounded up
