In the diagram below, the red angle $(\angle YAK)$ and the blue angle $(\angle OAT)$ are both right angles. If $\angle YAO=23^\circ,$ then what is the measure of $\angle KAT$?
Answer:a
Step-by-step explanation:
Answer:
Hey kroy21; the answer is 23°.
Step-by-step explanation:
Angle YAO and angle KAT are both complementary to angle OAK.
Angle OAK= 90°- Angle YAO
= 90° - 23°
= 67°
Then:
Angle KAT= 90° - Angle OAK
=90° - 67°
=23°

An electrician charges $20 for a service call plus $40 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service. What will be the total cost for 8 hours of work? 10 hours of work?
Answer:
Step-by-step explanation:
Regular charge- $20
Every hour of service cost- $40
Equation or slope intercept form-
C= 40h+20
Part 1- 20+40(8)=
40 multiplied by 8 320+20 = $340
Part 2- 20+40(10)=
40 multiplied by 10 400+20 = $420

9r + 5 – 4 = 4r + 5r – 12
Choose
Answer:
No solutions
Step-by-step explanation:
Simplify both sides of the equation as much as possible:
9r + 5 - 4 = 4r + 5r - 12
9r + 1 = 9r - 12
Both sides have "9r" which when cancel out, leave the equation as:
+1 = -12
This means there are no solutions.

A friend who works in a big city owns two cars, one small and one large. Three-quarters of the time he drives the small car to work, and one-quarter of the time he takes the large car. If he takes the small car, he usually has little trouble parking and so is at work on time with probability 0.8. If he takes the large car, he is on time to work with probability 0.6. Given that he was at work on time on a particular morning, what is the probability that he drove the small car
Answer:
0.8 = 80% probability that he drove the small car
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Being at work on time.
Event B: Driving the small car.
Probability of being at work on time:
0.8 of 0.75(small car).
0.6 of 0.25(large car). So
[tex]P(A) = 0.8*0.75 + 0.6*0.25 = 0.75[/tex]
At work on time, using the small car:
0.8 of 0.75
So
[tex]P(A \cap B) = 0.8*0.75 = 0.6[/tex]
What is the probability that he drove the small car
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.6}{0.75} = 0.8[/tex]
0.8 = 80% probability that he drove the small car

How many gallons of a 15% sugar solution must be mixed with a 5 gallons of a 40% solution to make a 20% solution
Answer:
20 gallons of 15% solution must be mixed with 5 gallons of 40% solution.
Step-by-step explanation:
40% of 5 gallons is 2 gallons of sugar
x represents the number of gallons of solution to be added.
15% of x is sugar.
The total amount of sugar must be equal to 20% of the final mixture.
The end mixture will be x + 5 gallons
Change percent to decimal for the equation:
.2(x +5) = .15x +2
.2x +1 = .15x +2
.2x - .15x = 2 -1
.05x = 1
x = 20
Check:
.2(20 +5) = .15(20) +2
.2(25) = 3 + 2
5 = 5 true
This means that adding 20 gallons of the 15% solution is adding 3 gallons of sugar [along with 17 gallons of water] to the 2 gallons of sugar in the original mixture.
20% of the 25 gallons, 5 gallons, of the final mixture is sugar. 80% [ 3+17 = 20 gallons] is water.

Brainleist please
The possible rational solutions for the given equation are x= −7.974656 and 0.038604.
What is an equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is [tex]4x^4+13x^3-124x^2+212x-8=0[/tex].
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Substitute x= ±1, ±1/2, ±1/4, ±2, ±4, ±8 in the given equation and verify
When x=1,
[tex]4(1)^4+13(1)^3-124(1)^2+212(1)-8=0[/tex]
⇒ 4+13-124+212-8=0
⇒ LHS ≠RHS
When x= -1
[tex]4(-1)^4+13(-1)^3-124(-1)^2+212(-1)-8=0[/tex]
⇒ 4-13-124-212-8=0
⇒ LHS ≠RHS
When x=1/2
[tex]4(\frac{1}{2} )^4+13(\frac{1}{2} )^3-124(\frac{1}{2} )^2+212(\frac{1}{2} )-8=0[/tex]
⇒ 1/4 +13/8 -31+106-8=0
⇒ LHS ≠RHS
When x=-1/2
[tex]4(-\frac{1}{2} )^4+13(-\frac{1}{2} )^3-124(-\frac{1}{2} )^2+212(-\frac{1}{2} )-8=0[/tex]
⇒ 1/4 -13/8 -31-106-8=0
⇒ LHS ≠RHS
Similarly Find every combination of ±p/q, where p is a factor of the constant and q is a factor of the leading coefficient.

Answer:
total -70
Step-by-step explanation:
x =18
y=-28
Z = -60
An Arithmetic series: 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)
The Total value is = -70
x = 18
y = -28
Z = -60
Calculation of Arithmetic SeriesAn Arithmetic series: 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)
1st an 2nd element difference is = 14 - 6 = 8
2nd and 3rd element difference is = - 6 - 2 = -8
3rd and 4th element difference is = - 2 + 10 = 8
4th and 5th element difference is = -10 + 18 = 8
The difference (x,y and z) is 8 and also it's negative because the series is lowering the previous value.
Now, Proof of x,y and z = - 8
14 - 8 = 6
6 - 8 = - 2
- 2 - 8 = - 10
- 10 - 8 = - 18
- 18 - 8 = - 26
-26 - 8 = -34
Therefore, The value is = total -70
x = 18
y = -28
Z = -60

Find all points on the x-axis that are 14 units from the point (4, -7).
(Simplify your answer. Type an ordered pair. Use a comma to separate answers as needed.)
Answer:
The points are: (16.12,0),(-8.12,0).
Step-by-step explanation:
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{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
Distance between two points:
Suppose we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Find all points on the x-axis that are 14 units from the point (4, -7).
Being on the x-axis mean that they have y-coordinate equal to 0, so the point is (x,0).
The distance is 14. So
[tex]\sqrt{(x-4)^2+(0-(-7))^2} = 14[/tex]
[tex]\sqrt{x^2 - 8x + 16 + 49} = 14[/tex]
[tex]\sqrt{x^2 - 8x + 65} = 14[/tex]
[tex](\sqrt{x^2 - 8x + 65})^2 = 14^2[/tex]
[tex]x^2 - 8x + 65 - 196 = 0[/tex]
[tex]x^2 - 8x - 131 = 0[/tex]
So [tex]a = 1, b = -8, c = -131[/tex]
[tex]\bigtriangleup = (-8)^{2} - 4(1)(-131) = 588[/tex]
[tex]x_{1} = \frac{-(-8) + \sqrt{588}}{2} = 16.12[/tex]
[tex]x_{1} = \frac{-(-8) - \sqrt{588}}{2} = -8.12[/tex]
The points are: (16.12,0),(-8.12,0).
