Answer:
r = 0.16
Step-by-step explanation:
C = 2·π·r
1 = 2·π·r
1/2 = π·r
0.5 = π·r
0.5 / 3.14 = r
0.16 = r

Answer:
x = 10, y = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The opposite sides of a parallelogram are congruent.
For LMNO to be a parallelogram then
ON = LM and OL = NM, that is
ON = LM
7x - 6 = 6x + 4 ( subtract 6x from both sides )
x - 6 = 4 ( add 6 to both sides )
x = 10 , then
NM = x - 9 = 10 - 9 = 1 and
OL = NM , that is
3y - 3 = 1 ( add 3 to both sides )
3y = 4 ( divide both sides by 3 )
y = [tex]\frac{4}{3}[/tex]

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
[tex]s=\dfrac{48}{b}[/tex]
Hence, the required expression is (48/b).
Alexis simplified 14/42 to 1/3 by using the greatest common factor (GCF) of 14 and 42
What number did alexis use?
A. 2
B. 14
C.42
D. 84
Answer: 14
Step-by-step explanation:
how do i find thhe greatest common factor?
Answer:
lets say you needed to find the greates comon factor of 20 and 5, you need to find the closest number they both go into, so 20. or if it was 3 and 10 it would be 30 because it is the closest thing they both go into, i hope i am right i am so sorry if i am wrong.

2x + y = 11
3x - y = 4
Answer:
[tex]x=3,y=5[/tex]Step-by-step explanation:
Add the equations together and solve for x.
[tex](2x + y )+ (3x - y) = 11 + 4[/tex]
[tex]5x=15[/tex]
[tex]x=3[/tex]
Use equation [tex]2x+y=11[/tex] to solve for y.
[tex]2(3) +y=11[/tex]
[tex]6+y=11[/tex]
[tex]y=11-6[/tex]
[tex]y=5[/tex]
Graph the equation y = -x^2+ 8x – 15 on the accompanying set of axes. You must plot 5 points including the roots and the vertex. Using the graph, determine the roots of the equation –x^2 + 8x – 15 = 0.
Answer:
Graph below
Step-by-step explanation:
Graph of the Quadratic Function
We are given the function:
[tex]y=f(x)=-x^2+8x-15[/tex]
Select 5 values of x={2,3,4,5,6}
And calculate the corresponding values of y:
[tex]f(2)=-2^2+8*2-15=-4+16-15=-3[/tex]
[tex]f(3)=-3^2+8*3-15=-9+24-15=0[/tex]
[tex]f(4)=-4^2+8*4-15=-16+32-15=1[/tex]
[tex]f(5)=-5^2+8*5-15=-25+40-15=0[/tex]
[tex]f(6)=-6^2+8*6-15=-36+48-15=-3[/tex]
We have obtained the points
(2,-3) (3,0) (4,1) (5,0) (6,-3)
Now we plot them in the graph below.
It can be noted three remarkable points:
The vertex is located at (4,1)The roots are located at (3,0) and (5,0)The roots of the equation
