AB have a 90° angle with BC, so the angles ABD + CBD = 90
(7x - 9)° + 4x° = 90°
7x + 4x = 90 + 9
11x = 99
x = 99/11
x = 9
So the angles are:
7x - 9 -> 7.9 - 9 = 54°
4.9 = 36°
Answer:
m<CBD equals 54
Step-by-step explanation:
Since that is a right angle do (7x-9)+(4x)=90
=11x-9=90
=11x=99
x=9
CBD=7x-9
7(9)-9=54
Hope this helps

Evaluate the terms inside of the parentheses
Step-by-step explanation:
According to PEMDAS, you always start solving an equation by answering what is inside of the parentheses first. (That's what the 'P' in PEMDAS stands for!)
Therefore, this is the correct answer.
What is the slope of the line passing through the following points:
(1,3) & (5,0)
Answer:
-3/4
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
= (0-3)/(5-1)
= -3 / 4
Answer:
Step-by-step explanation:
[tex]slope=\frac{y_{2}-y_{1}}{y_{2}-y_{1}}\\\\=\frac{0-3}{5-1}\\\\=\frac{-3}{4}[/tex]

Dogs in the GoodDog Obedience School win a blue ribbon for learning how to sit, a green ribbon for learning how to roll over, and a white ribbon for learning how to stay. There are 100 dogs in the school.
62 have blue ribbons, 55 have green ribbons, and 63 have white ribbons.
32 have a blue ribbon and a green ribbon 31 have a green ribbon and a white ribbon; 38 have a blue ribbon and a white ribbon.
16 have all three ribbons.
How many dogs have not learned any tricks?
Answer:
5
Step-by-step explanation:
The 32 that have blue and green ribbons include the 16 that have all three, so there are only 32 -16 = 16 that have only blue and green ribbons.
The 31 that have green and white ribbons likewise include the 16 with all three, so there are only 31 -16 = 15 that have only green and white ribbons.
The 38 that have blue and white ribbons include the 16 with all three, so there are only 38 -16 = 22 that have only green and white ribbons.
__
If we add the numbers of blue, green, and white ribbons, we are counting twice the numbers that have 2 ribbons, and 3 times the numbers that have 3 ribbons. We want to count each kind of ribbon-holder only once. Hence the number of individual dogs with any number of ribbons is only ...
62 +55 +63 -(16 +15 +22) -2(16) = 95
Of the 100 dogs, 95 have ribbons, so 5 dogs have not learned any tricks.

What would happen if someone sarhpled a basketball team to find the
average height of a school's student body?
Answer:
Basketball players are normally taller so it would not be accurate
Answer: It wouldn't be valid or reliable because the basketball team is not indicitive of the entire student body. Additionally, sampling just the basketball team is not random nor is it likely a large enough sample size (unless it is a tiny school).
Step-by-step explanation:
Look at Attachment, giving a lot of points for the answer to questions.
Answer:
see below
Step-by-step explanation:
1.
m = (y2-y1)/(x2-x1)
= (90-80)/(0-1)
= 10/-1
=-10
The slope is -10 ft/s
This means the height decreases 10 ft for every second that passes
This is not proportional because it has to go through the point (0,0)
4.
m = (y2-y1)/(x2-x1)
= (1000-0)/(3-0)
= 1000/3
=1000/3
The slope is $1000/3
This means the 1000 dollars is sold every 3 days
This is proportional because it goes through the point (0,0) and has a constant slope
Step-by-step explanation:
Let 'm' be slope
HAWK DIVING TOWARDS PREY:
m = (y2 - y1) / (x2 - x1)
= (90 - 80) / (0 - 1)
= 10 /- 1
= - 10
This is not proportional because it doesn't to go through the point (0, 0)
BOOK SALES:
m = (y2 - y1) / (x2 - x1)
= (1000 - 0) / (3 - 0)
= 1000/3
This is proportional because it goes through the point (0, 0)

A car’s speed before a sudden stop can be estimated by the formula
S = √(30gk) , where
S = speed of the car in mph,
g = drag factor, and
k = length of skid mark in feet.
The drag factor during a recent crash was 1. What was the approximate speed of the car if it created skid marks 30 feet long?
a. 30 mph
b. 45 mph
c. 60 mph
d. 90 mph
Answer:
S = 30 mph
Step-by-step explanation:
A car’s speed before a sudden stop can be estimated by the formula :
[tex]S=\sqrt{30gk}[/tex]
Here,
S = speed of the car in mph,
g = drag factor, and
k = length of skid mark in feet
If drag factor is 1, k = 30 feet
So,
[tex]S=\sqrt{30\times 1\times 30}\\\\S=30\ mph[/tex]
Therefore, the correct option is (a) 30 mph.

In the xy-plane, a line that has the equation y = c for some constant c intersects a parabola at exactly one point . If the parabola has the equation y=-x^ 2 +5x. what is the value of c?
Answer:
c=6.25
Step-by-step explanation:
If a line that is flat (has a slope of zero) hits only one point of the parabola, it means that point is the vertex of the parabola.
In this case your equation is ---
y= –x^2 + 5x
--- and you just need to write in vertex for the equation:
y=a(x–h)^2 + k
y= –(x–2.5)^2 + 6.25
The vertex is (h,k) or (2.5,6.25)
Since the equation is "y=", k=c
or c=6.25
Thank You.
In this question:
We have to find the point of intersection of the line and the parabola.To do this, we have to apply concepts needed to solve a quadratic equation.Doing this, we find that the value is: [tex]c = \frac{25}{4}[/tex]
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
Line: y = c
Parabola: y = -x^ 2 +5x.
The intersection is at the point:
[tex]-x^2 + 5x = c[/tex]
[tex]-x^2 + 5x - c = 0[/tex]
[tex]x^2 - 5x + c = 0[/tex]
Which is a quadratic equation with [tex]a = 1, b = -5[/tex].
The line and the parabola intersect at exactly one point, which means that the quadratic equation has one solution, that is, [tex]\Delta = 0[/tex].
Since:
[tex]\Delta = b^{2} - 4ac[/tex]
It means that:
[tex]b^2 - 4ac = 0[/tex]
We use this to find the value of c.
[tex](-5)^2 - 4(1)(c) = 0[/tex]
[tex]4c = 25[/tex]
[tex]c = \frac{25}{4}[/tex]
The value is: [tex]c = \frac{25}{4}[/tex]

Susie leases a $13,000 car for three years. The estimated resell value at the end of the lease term is $7,683. The interest rate is 5.1%. Susie will pay on her lease monthly. What is the depreciation fee?
a) $43.95
b) $147.69
c) $249.53
d) $7,683.00
Answer:
The depreciation fee is the difference between the initial value of the car and its estimated resell value at the end of the lease term. In this case, the depreciation fee is $13,000 - $7,683 = $5,317.
To calculate the monthly payment on the lease, you would need to know the length of the lease in months, the interest rate, and the depreciation fee. You can then use the following formula to calculate the monthly payment:
Monthly payment = (Interest rate / 12) x (Initial value - Resell value) / Length of lease in months
For example, if the length of the lease is 36 months, the monthly payment would be:
Monthly payment = (5.1% / 12) x ($13,000 - $7,683) / 36 months = $114.78
Keep in mind that this is just an example calculation and the actual monthly payment on Susie's lease may be different depending on the specific terms of the lease agreement.

Which variable is easiest to solve for?
A.The easiest to solve for is x in the first equation.
B.The easiest to solve for is y in the first equation.
C.The easiest to solve for is x in the second equation.
D.The easiest to solve for is y in the second equation.
Answer:
BStep-by-step explanation:
y in equation 1, since you just
-4x + y = 6
add 4x to both sides to get
y = 4x + 6
while for the rest of the variables in both equations, you need at least two steps
Thus, the answer is B
Answer:
B. The easiest to solve for is Y in the first equation.
Step-by-step explanation:
Since the y has no coefficient in both equations, we look at the steps we take to solve. Equation 2 has to make you multiply negative one by both sides to make y positive, and THEN you would have to subtract 5x from both sides. However, with the first equation, all we need to do to solve for Y is add 4x to both sides. The answer? B. The easiest to solve for is Y in the first equation.
