Answer:
x=4
Step-by-step explanation:
5(x-10) = 30- 15x
5x - 50= 30 - 15x
+15x +15x
20x - 50 = 30
+50 +50
20x = 80
/20 /20
x = 4
Hope this helps!
Answer:
4188.8 cm^3
Step-by-step explanation:
We can calculate the volume of a sphere by using the following equation:

(r=radius)
so let's just plug in what we know
4/3(pi)(10)^3
we can calculate this with a calculator to get 4188.8 cm^3.
Answer:
D
Step-by-step explanation:
∠ 6 is formed by the 2 lines that intersect at D
then the vertex of ∠ 6 is D
Answer:
22%
Step-by-step explanation:
x/100 * 160=35
160x=3500
21.875
hence to the nearest percent: 22%
Polynomial requirements
1. never divide by a placeholder
2. variable exponent has to be a whole number
3. can't have infinte terms
by 1. we eliinate 2nd one
by 2. we eliminate first one (√x=x^1/2) and 3rd one because it has an exponent in placeholder
thie leaves us with last one
f(x)=2x³-5x⁵-(2/9)x²+9
last one is answer
