Answer:
46
Step-by-step explanation:
6 times 2 is 12
23 times 2 is 46
Answer:
5 units
Step-by-step explanation:
3x + 4y = 8
4y = -3x+8
y = -3/4+2
The shortest distance between a point and a line is the perpendicular line.
Slope of the perpendicular line: 4/3 and point (-3,-2)
b = -2-(4/3)(-3) = 2
Equation of the perpendicular line: y=4/3x+2
y is equal y
4/3x+2= -3/4x+2
4/3x +3/4x = 2-2
x = 0
Plug x=0 into one of the equations to find y
y = 4/3(0) + 2
y = 2
(0,2) and (-3,-2)
Distance = sqrt [(-3-0)^2 + (-2-2)^2]
Sqrt (-3)^2+ (-4)^2
Sqrt 25 = 5
Filling in the given information, you are asked to find "r" from
64π = 4πr²
Dividing by 4π gives
16 = r²
And taking the square root tells you
4 = r
The appropriate choice is ...
C. 4
Circle b:
Diameter = x
Radius =
Area =
Circle a:
Diameter =
Radius =
Area =
Thus,
Area of circle b to area of circle a
=
÷
=
×
= 4
Hence, the area of circle b is
4 times the area of circle a.
Answer:
x = 7.2
Step-by-step explanation:
5x - 36 - 11x = 3x + 36 + 3x
add like values together:
16x - 36 = 6x + 36
add 36 to each side:
10x = 72
divide by 10 to get x alone:
x = 7.2
