Answer:
2:4 means one part is 2/(2+4)=1/3 of AB and the other part is 2/3 of AB
Step-by-step explanation:
Add 1/3 of the distance from -2 to 4. (1/3)(4+2)=2. -2+2=0 The x coordinate is 0
Subtract 1/3 of the distance from 6 to -6, (1/3)6+6)=4 6-4=2 The y coordinate is 2
The point is (0,2)
Check the answer
distance from (-2,6) to (0,2) is square root of (-2)^2 + (4)^2 = sqr20 = 2(5)^2
distance from (0,2) to (4,-6) is square root of (4)^2 +(8)^2 = sqr80 = 4(5)^2
First distance is half the 2nd distance, so the point divides AB into 2 parts in a ratio of 2:4

Which is an example of dependent events?
choosing two socks from a drawer of black and white socks without replacement
choosing two numbered slips from a hat with replacement
rolling a die three times
spinning a spinner two times
Answer:
choosing two socks from a drawer of black and white socks without replacement
Step-by-step explanation:
Dependent events have results that depend on each other. When I take one sock out, there are less socks in the drawer to pick from. The probability of picking a certain sock changes because the number of socks are different when I do not put the sock back. That makes the events dependent.
When I put the sock back, the probability goes back to what it was before I took the sock, and now the results do not depend on each other, so when they are replaced, they are independent
Answer:
choosing two socks from a drawer of black and white socks without replacement
Step-by-step explanation:
choosing two socks from a drawer of black and white socks without replacement are dependent events because the available options for the second selection depends on which colour was the first sock

A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the pan?
Answer:
The first choice is correct
Step-by-step explanation:
$32.00 x 15% = 4.80. 32.00-4.80=27.20. Another way to work it is the first choice, subtracting 15% from 100% and then multiplying 85% by $32.00. Same answer

Answer:
[tex]\sqrt{89}[/tex]
Step-by-step explanation:
distance = [tex]\sqrt{(x_{2}- x_{1})^{2} + { (y_{2} - y_{2} } ){^2} }[/tex]
Let:
(x₁ , y₁) = (0 , 5)
(x₂ , y₂) = (8 , 0)
Plug in the corresponding numbers to the corresponding variables:
Remember to follow PEMDAS. Solve the parenthesis first:
distance = [tex]\sqrt{(8- 0)^{2} + { (0 - 5 } ){^2} }[/tex]
distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]
Solve for the powers next:
distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]
distance = [tex]\sqrt{64 + 25}[/tex]
Simplify:
distance = [tex]\sqrt{64 + 25}[/tex]
distance = [tex]\sqrt{89}[/tex]

Which of the following is an example of a function
whose graph in the xy-plane has no x-intercepts?
A) A linear function whose rate of change is not
B) A quadratic function with real menos
© A quadratic function with no real xeros
D) A cubic polynomial with at least one real zero
Answer: Option C.
Step-by-step explanation:
A function goes trough the x-axis when f(x) = 0 for some value of x.
For example, when we say that a quadratic function has no real zeros, this means that the determinant is less than zero, so the roots of the equation:
a*x^2 + b*x + c = 0
are complex roots, this means that for the function:
f(x) = y = a*x^2 + b*x + c
there is not a real number x such f(x) = 0
So the correct option is C.
The quadratic function with no real zeros is an example of a function whose graph in the xy-plane has no x-intercepts.
What is x-intercept?The x-intercept is the point on the coordinate at which a line, curve or plane intersect with the x-axis.
The example of a function whose graph in the xy-plane has no x-intercepts has to find out.
X-intercept is the point over the graph where,
[tex]y=f(x)[/tex]
Here, x is the roots of the function.
For no value of x-intercepts, the function become,
[tex]y=0[/tex]
[tex]f(x)=0[/tex]
Here, the zeros and roots are the same, where function become equal to zero.
Thus, the quadratic function with no real zeros is an example of a function whose graph in the xy-plane has no x-intercepts.

How to find if a pair of figure is not dilated version of each other?Dilation of a figure will leave its sides get scaled (multiplied) by same number.
Thus, suppose if a rectangle is dilated, and its sides were of length = L and width = W, then its dilated version would be having length = Ln, and width = Wn where n is the factor of scaling.
At image B (-24, -12) and pre image B (-18, -9),
we can work out the scale factor by (-24/-18) and (-12/-9) both equal 4/3
Using the scale factor to go from the pre image to the image,
We can find C coordinate by pre image C by the scale factor.
C is (-13.5 x 4/3) and (18 x 4/3)
C is (-18, 24)
So, The scale factor is 4/3, which is the mixed numeral of 1 1/3.
To find the pre image of point A;
A is (12/(4/3)) and (-6/(4/3))
A is (9, - 4 1/2)
Hence, the true statement are;
The coordinates of C prime are (–18, 24).
The scale factor is 1 1/3 .
The coordinates of A are (9, –4.5).

The width of a rectangle is 2 less than twice its length. If the area of the rectangle is 182 cm 2 , what is the length of the diagonal?
Answer:
20.93cm
Step-by-step explanation:
The shape of the solid is rectangle
Area = length × width
But the width (w) = 2 times the length minus 2
W = 2L - 2
A = L × (2L - 2)
Area of the rectangle = 182cm²
A = 2L² - 2L
182 = 2L² - 2L
2L² - 2L - 182 = 0
L² - L - 91 = 0
Solving the equation using quadratic formula,
A = 1, b = -1, c = -91
L = [-b±√(b² - 4ac)]/2a
L = [-(-1) ± √((-1)² - 4*1*(-91))] / 2(1)²
L = [1 ± √(1² + 364)] / 2
L = [1 ± √(365)] / 2
L = (1 ± 19.10) / 2
Note : Since we're working with length, we can't have a negative value as a solution hence we would not test both sides
L = (1 + 19.10) / 2 = 10.05cm
Width = 2L - 2
W = 20.1 - 2 = 18.10cm
Length = 10.05cm
Width = 18.10cm
Diagonal of the rectangle = ?
To find the diagonal, we'll use pythagorean theorem,
A = diagonal
B = length
C = width
a² = b² + c²
a² = (10.05)² + (18.10)²
a² = 110.25 + 327.61
a² = 437.86
a = √(437.86)
a = 20.93cm
The diagonal of the rectangle is 20.93cm

Find the value of x.
3x-6
Answer:
x = 7
Step-by-step explanation:
We can use ratios to solve
3x-6 10
---------- = -------------------
12+(3x-6) 10+8
Simplifying
3x-6 10
---------- = -------------------
(3x+6) 18
Using cross products
18(3x-6) = 10(3x+6)
Distribute
54x - 108 = 30x +60
Subtract 30x from each side
54x-30x -108 = 60
24x -108 = 60
Add 108 to each side
24x = 60+108
24x = 168
Divide each side by 24
24x/24 = 168/24
x =7

Jack divided his fortune of $92,000 into 8 equal parts. He gave 4 parts to his wife, 1 part to his son and divided the remaining 3 parts equally among 5 charities.
How much more money did his son get than each charity?
Answer:
4,600
Step-by-step explanation:
92,000/8= 11500
11500 x 4= 46000 to his wife
11500 for the son
92000-57500= 34500
34500/5= 6,900 each charity
11500-6900= 4600 is how more he is getting than each charity
Answer:
4600 more money
Step-by-step explanation:
92000 ÷ 8 = 11500
1 part to his son
3(11500)= 34500
34500 ÷ 5 = 6900
11500-6900= 4600
