there are 8 pairs of black socks and 4 pairs of white socks in a drawer. how likely is it that you would randomly pick a black pair of socks
Answer: I would pick black socks too because there are 8 pair of black socks with 4 pairs of white socks and 8 is > greater than 4.
Okay, so...
If there are 8 black socks + 4 white socks, then it = 12 socks totall. the fract Would Be 8/12 but if you simplify it, its 4/6, if you simplify it one more time you final answer is.....
You will have a 2/3 chance of picking a black sock.

What is the surface area of the cylinder shown? Use 3.14 for pie. 4cm for the Radius, and 9cm for the height.
==============================================
Work Shown:
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*(4)^2 + 2*3.14*4*9
SA = 326.56
Notes:
The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.Answer:

Ian bought a used car. The value, y , of the car x years after his purchase is modeled by the equation y = 6500(0.875)x . What was the value of the car when Ian bought it?
Answer:
6500
Step-by-step explanation:
y = 6500(0.875)^x
When bought x = 0
y = 6500(0.875)^0
A number raise to 0 equals 1
y = 6500 * 1
y = 6500

(x−3y=5)+(8x−7y=6)
Answer:
[tex]x=1\frac{2}{9} +1\frac{1}{9}y[/tex]
Step-by-step explanation:
x - 3y + 8x - 7y = 5 + 6
9x - 10y = 11
9x - 10y + 10y = 11 + 10y
9x = 11 + 10y
9x ÷ 9 = 11 + 10y ÷ 9
[tex]x=1\frac{2}{9} +1\frac{1}{9}y[/tex]
Answer:
x = -1
y = -2
Step-by-step explanation:
x - 3y = 5 ----------------(I)
8x - 7y = 6 ----------(II)
Multiply equation (I) by (-8) and then add the two equations
(I)*(-8) -8x + 24y = -40
(II) 8x - 7y = 6 {Now add and x will be eliminated}
17y = -34 {Divide both sides by 17}
y = -34/17
y = -2
Plugin y =-2 in equation (I)
x - 3*(-2) = 5
x + 6 = 5 {Subtract 6 from both sides}
x = 5 - 6
x = - 1
Find m angle PMA +m angle CMT.
.
.
.
The last option: D. 84
Answer:
84
Step-by-step explanation:
m∠CMT=101-54=47
m∠PMA=37, So
m∠PMA+m∠CMT=47+37=84
The sum of the angle ∠PMA + ∠CMT will be 84 so option (D) will be correct.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
In other words, the angle is the measurement of the angular distance. For instance, we have a meter and an inch for linear motion, but we don't have a measurement for angular rotation, therefore the angle is helpful in determining angular rotation.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
The Angle of description has given below
∠CMT=101-54=47
∠PMA=37, means
∠PMA+∠CMT = 47+37 = 84 hence, 84 will be the correct answer.

Solve the simultaneous equation 4x + 3y = -2 8x + 3y = 14
Answer:
x = 4 and y = -6
Step-by-step explanation:
Solve by elimination by multiplying the first equation by -2:
-8x - 6y = 4
8x + 3y = 14
Add them together and solve for y:
-3y = 18
y = -6
Plug in -6 as y into one of the equations and solve for x:
8x + 3y = 14
8x + 3(-6) = 14
8x - 18 = 14
8x = 32
x = 4
So, the solution is x = 4 and y = -6
Answer:
x = 4
y = -6
Step-by-step explanation:
4x + 3y = -2
8x + 3y = 14
Multiply the second equation by -1
4x + 3y = -2
-8x - 3y = -14
--------------------------
-4x = -16
Divide by -4
-4x/-4 = -16/-4
x = 4
4x+3y = -2
4*4 +3y = -2
16 +3y = -2
3y = -2-16
3y = -18
y = -6
which statement is true about this graph
A: The slope is -6
B: the relationship is proportional
(I already know that:
The equation of the line is y= - 3x
and that the slope is negative.)
B: the relationship is proportional
Which statement is not true about the absolute value of -6?
A. It descrlbes the distance between -6 and 0 on the number line.
B. It equals the absolute value of 6.
C. It describes the distance between 6 and -6 on the number line.
D. It can be expressed as |-6|.
Answer:
C
Step-by-step explanation:
All the other answers are the same worded differently except c.
The distance between 6 and -6 is 12 so that is not correct for the absolute value of -6
Solve for the missing angle measurement ?
Answer:
75°
Step-by-step explanation:
180°-105°=75°
Hope this helps! :)
Answer:
75 degrees.
Step-by-step explanation:
The sum of both angles is 180 degrees, they are supplementary. Therefore, subtracting the measurement of the first angle from 180 will give you your answer.
180 - 105 = 75

Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, obtuse, acute and right angled triangle.
In a right angled triangle, the hypotenuse is the side with the longest length. Pythagoras theorem states that the square of the hypotenuse is equal to the sum of the square of the remaining two legs
The value of x can be gotten using Pythagoras theorem.
y² = h² + 3² (1)
x² = h² + 3² (2)
(3 + 3)² = x² + y² (3)
Substituting y² = h² + 3² and x² = h² + 3² into equation 3 gives:
(3 + 3)² = (h² + 3²) + (h² + 3²)
36 = h² + h² + 9 + 9
2h² + 18 = 36
2h² = 18
h² = 9
h = 3
Put h = 3, into equation 2 to get the value of x:
x² = 3² + 3²
x² = 9 + 9 = 18
x = √18 = 3√2 units

Answer:
See below.
Step-by-step explanation:
4.2 is 4 and 2 tenths.
4 is 40 tenths.
That means that 4.2 is 40 tenths plus 2 tenths, or 42 tenths.
First line: 4.2 / 6 = 42 tenths / 6
In the second line, we divide 42 tenths by 6. Since 42 divided by 6 = 7, then 42 tenths divided by 6 equals 7 tenths.
Second line: 4.2 / 6 = 7 tenths
In the third line, we write 7 tenths as a number. 7 tenths is the same as 0.7.
Third line: 4.2 / 6 = 0.7

Find the vertex of y=-2(x-4)2 + 3 and identify it as a minimum or a maximum
Answer:
Step-by-step explanation:
Remark
The minus sign in front of the 2 means that the quadratic has a maximum.
The vertex is already written in vertex form.
y= - 2 (x - 4)^2 + 3
The vertex is (4,3). Notice that the sign on the 4 changes. What you are trying to do is find the maximum point. That occurs when the minus number is made to be 0, which occurs when x = 4. The maximum y value is 3 when that happens.
I have enclosed a graph to show you all the details. Notice the maximum is when I've said it was and the roots have also been calculated.
