When two or more points on a graph has a linear association it means that the slope of the graph at thos points are equal.
Answer:
130
Step-by-step explanation:
<6 and <8 are vertical angles and vertical angles are equal
<6 = <8
130 = <8
Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
Answer:
48
Step-by-step explanation:
If he had 50 chocolates and give 3 to each friend them you find the closest number to 50 that 3 can go into. The biggest number that 3 can go into is 16. 3 times 16 is 48. And with 48 there is still 2 left over.
Answer:
z-4
Step-by-step explanation:
z(5z²-80) ÷ 5z(z+4) = z-4
Step-by-step explanation:
Given: z(5z²-80) ÷ 5z(z+4)
Calculation:
First we factor numerator z(5z²-80)
Take out 5 from 5z²-80 and we get 5z(z²-16)
Now we factor 16 = 4²
5z(z²-4²)
Using formula, (a²- b²)=(a+b)(a-b)
5z(z²- 4²)⇒5z(z+4)(z-4)
Simplified fraction
5z(z+4)(z-4) ÷ 5z(z+4)
Cancel like factor from numerator and denominator
⇒ z-4
Thus, z(5z²-80) ÷ 5z(z+4) = z-4
