Answer:
d. AB = 54
Step-by-step explanation:
The triangle is isosceles, so AB = AC.
(4x +6) = (5x -6)
12 = x . . . . . . . . . . . . add 6-4x to both sides
Then the length of AB is ...
AB = 4x +6 = 4(12) +6 = 48 +6

Drag each number to show whether it is equal to 2/10, 2/100, or neither.
Answers
Answer:
20/10 goes to neither since it equals 2
0.02 goes to 2/100 since it is the same as 0.02
200 goes to neither because it is over 2/10 and 2/100
0.20 goes to 2/10 since 2/10 is equal to 0.20
2.0 goes to neither because it equals 2

Step-by-step explanation:
Two numbers multiply to be 4 and add to be -5
Answers
Answer:
-1, -4
Step-by-step explanation:
x + y = -5
x×y = 4
=>
x = -5 - y
=> (-5 - y) × y = 4
-5y - y² = 4
y² + 5y + 4 = 0
the solution for a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
a = 1
b = 5
c = 4
x = (-5 ± sqrt(25 - 16))/2 = (-5 ± 3)/2
=> x = -2/2 = -1 or x = -8/2 = -4
=> y = 4/-1 = -4 or y = 4/-4 = -1
since the sequence in an addition and multiplication does not make any difference, the two numbers are simply -1 and -4

How many solutions does this equation have one, none, or infinite 12+2i-i=9i+6
Answers
Answer:
i=3/4
Step-by-step explanation:
Assuming that we are treating "i" as a variable and not the constant "i":
12+2i-i=9i+6
12+i=9i+6
12=8i+6
6=8i
8i=6
i=6/8
i=3/4
Therefore, the equation has only one real solution which is i=3/4
Point k is on line segment JL. Given JL = 4x+2, KL = 5x-6, and JK = 3x, determine the numerical length of JK.
Answers
Answer:
6 units
Step-by-step explanation:
JK + KL = JL
3x + 5x-6 = 4x+2
8x-6 = 4x+2
subtract 4x from each side to get:
4x - 6 = 2
add 6 to each side to get:
4x = 8
x = 2
JK = 3x and x=2 so JK = (3)(2) or 6
The numerical length of JK = 6
What is Line Segment?
" A line segment is a line section that can link two points. "
We know that point K is divide line JL
Given that JL = 4x+2
KL = 5x-6
JK = 3x
So, Equation is JK+KL = JL
3x+5x-6 = 4x+2
8x-6 = 4x+2
8x-4x = 2+6
4x = 8
x = 8/4
x = 2
So , numerical length of JK = 3x
JK = 3×2
JK = 6
Hence , length of JK is 6

Answer:
A. 54 pie cm³
Step-by-step explanation:
height of the cylinder = 6 × radius of one sphere.
= 6 × 3
= 18 cm
as we can see 3 spheres make up the height of one cylinder,
height of one sphere = 6 cm (3 + 3)
with three spheres it becomes = 6 × 3
= 18 cm
volume of a cylinder = [tex]\pi[/tex] r² h= [tex]\pi[/tex] × (9)² × 18
= 27 × 6 [tex]\pi[/tex]
volume of a sphere = 4/ 3 × [tex]\pi[/tex] 3³= 36 [tex]\pi[/tex]
for 3 spheresvolume = 3 × (36 [tex]\pi[/tex] )
= 27 × 4 [tex]\pi[/tex]
volume of the empty space
= volume of cylinder- volume of 3 spheres
= 27 × 6 [tex]\pi[/tex] - 27 × 4 [tex]\pi[/tex]

Answer:
1.
Step-by-step explanation:
The mean score is (8+6+9+9+8+8)/ 6
= 48/8
= 8.
Deviations from the mean are 0 , -2, 1, 1, 0, 0
Squares of these deviations are 0, 4, 1, 1, 0, 0
So the variance = (0 + 4 + 1 + 1 + 0 + 0)/ 6 = 1
