Okay so, to solve these problems what you're gonna want to do is substitute the given x and y values into the equation.
For example, number 7.
11(d-c) + 3(c+d), when c=6, d=9
if d=9, you will substitute the d in the problem to 9.
11(9-c) + 3(c+9)
if c=6 you will substitute c for 6.
11(9-6) + 3(6+9)
You can solve now that you have a simpler problem to work with.
11(9-6) + 3(6+9) first...
11(9-6) 11*9=99 11*-6=-66, so, 11(9-6)= 99-66= 33.
3(6+9) 3*6=18 3*9=27 18+27=45
33+45=78
Your answer for number 7 is 78.
Hope this helps, just do the same for the other problems like this one.

Answer:
x = 40°Step-by-step explanation:
In the question we arw given with three angles that are z
Angle 1 = x°Angle 2 = 70°Angle 3 = 110°( Angle 1 , Angle 2 or Angle 3 aren't given in Question , we are just giving names for given angle . So that there's ease on explanation )
And we have asked to find th value of angle 1 i.e. x .
Solution : -
As we can see in the question that ,
Angle 1 + Angle 2 = Angle 3 ( Vertically Opposite Angles )Vertically Opposite Angles : -
When two lines intersect each other then the two angles formed by them at a specific point are equal .
[tex] \longmapsto x° + 70° = 110°[/tex]
Subtracting 70 from both sides :
[tex]\longmapsto x° + \cancel{70° }- \cancel{70° }= 110° - 70°[/tex]
On further calculation :
[tex] \longmapsto \purple{ \boxed{ \mathfrak{ x° = 40 {°} }}}[/tex]
Therefore , value of x is 40° .Verification : -
We are verifying our answer by substituting value of x . So ,
x + 70° = 110°40° + 70° = 110°110° = 110°L.H.S = R.H.SHence , Verified .Therefore, our value for x is correct

Answers
Probabilities are used to determine the chances of events
The probability that an employee of the company is single or has a college degree is 0.733
How to determine the probabilityThe given parameters are:
n = 600 --- the number of employees
College graduate = 400
Single graduate = 100
Single and college graduate = 60
The number of people that are college graduate or single are:
n(Single or college graduate) = 400 + 100 - 60
Evaluate
n(Single or college graduate) = 440
The probability is then calculated as:
p = 440/600
Evaluate the quotient
p = 0.733
Hence, the probability that an employee of the company is single or has a college degree is 0.733

Angle of depression is the angle from horizontal line to the line of sight. The distance from building of the sculpture is: Option d: 128. 67 feet.
What is angle of depression?You look straight parallel to ground. But when you have to watch something down, then you take your sight up by moving your head down. The angle from horizontal to the point where you stopped your head is called angle of depression.
For the given case, referring to the figure, we have:
Length of BC = |BC| = 60 ft.
Length of AB = |AB| = x ft (distance of sculpture from building horizontally).
∠CAB = 25°
Thus, using tangent ratio from point of view of ∠CAB, we get:
[tex]\tan(25^\circ) = \dfrac{|BC|}{|AB|} = \dfrac{60}{x}\\\\x = \dfrac{60}{tan(25^\circ)} \approx 128.67 \: \rm ft[/tex]
(value of tan25° was calculated from calculator available online)
Thus,
The distance from building of the sculpture is: Option d: 128. 67 feet.

If x > 2, find lx-2l
Help pleaseee
Answers
Explanation:
If x > 2, then x-2 > 0 after subtracting 2 from both sides.
Since x-2 is always positive when x > 2, this means the absolute value bars around the x-2 aren't needed. The results of |x-2| and x-2 are perfectly identical.
For example, if we tried something like x = 5, then
x-2 = 5-2 = 3|x-2| = |5-2| = |3| = 3Both outcomes are 3. I'll let you try other x inputs.
So because |x-2| and x-2 are identical, this means |x-2| = x-2 for all x > 2.
In short, we just erase the absolute value bars.

What is the center of a circle represented by the equation (x−5)2 (y 6)2=42? (−6,5) (−5,6) (5,−6) (6,−5).
Answers
The center of the circle is (5, -6). Option C shows the center of the circle.
What is a circle?
A circle can be defined as the set of all points in the plane that are a fixed distance from a fixed point on the plane.
Given that the equation of the circle is,
[tex](x-5)^2+(y+6)^2=42[/tex]
We know that the general form of the equation of the circle is,
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Where h, k is the center of the circle and r is the radius of the circle.
Compare the given equation with the general form of the equation, we get,
[tex](x-h) = (x-5)[/tex] and [tex](y-k) = (y+6)[/tex] and [tex]r^2 = 42[/tex]
For x-axis,
[tex](x-h) =(x-5)[/tex]
[tex]h = 5[/tex]
For y-axis,
[tex](y-k) = (y+6)[/tex]
[tex]k = -6[/tex]
Hence we can conclude that the center of the circle is (5, -6). Option C shows the center of the circle.

The length of the base of a triangle is twice its
perpendicular height. If its area is 36 cm2, find
its length and perpendicular height.
Answers
Answer: height = 6, length = 12
Step-by-step explanation:
Let the length of the height = x.
Then, the length of the base = 2x
The formula for the area of a triangle is base*height/2, which equals 36 in this case.
Therefore, x*2x/2 = 36
x^2 = 36
x = 6, 2x = 12
Thus, the height = 6 and then length = 12

The relationship between money earned and hours worked is linear. Joe computes the slope between (4, 30) and (12, 90), then computes the slope between (4, 30) and (10, 75). How do the two slopes compare?
The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the x-axis.
The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the y-axis.
The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.
The slope between (4, 30) and (12, 90) is less because 4 is a factor of 12 and 30 is a factor of 90.

What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given the table:
Bert’s store

Game: 6,12,18,24,30
Gloria’s store
Books: 5,10,15,20,25.
Games: 8, 16, 24, 32,40,
Since the fourth data of the birt store has an equal base to the third data of Gloria's store.
Thus, we can compare the data from the upper tables
So, 16 > 15

The distance between the bird and the brick is 7.5 feet. Hence the correct answer is B. It is to be noted that the question is an exercise relating to solving the sides of a right-angled triangle.
What is the formula for finding the sides of a right-angled triangle?
The formulas for finding the sides of a right-angled triangle are:
For Side A, a = [tex]\sqrt{ (c^{2} - b^{2} })[/tex]
For Side B, b = [tex]\sqrt{ (c^{2} - a^{2} })[/tex]
For Side C, c = [tex]\sqrt{ (a^{2} + b^{2} })[/tex]
In this case, base - b has been given as 4.5 feet;
the height - a of the pole has been given as 6 feet. Note that the portion due west is a trick addition that is irrelevant to the solution.
Hence, c is equaled: [tex]\sqrt{ (6^{2} + 4.5^{2} })[/tex]
= [tex]\sqrt{ ( 36+ 20.25 })[/tex]
= [tex]\sqrt{56.25}[/tex]
