Answer: (consider leaving a thanks)
Since the equation representing the total cost is C, we would write:
C = (rest of equation will go here)
Then, since the price goes up with the number of hours (h) by 65$ each hour, we would write it as (65h)
C = 65h (Final part!)
Finally, since 150$ is added on, and isn't connected to the number of hours we would write the equation like this:
C = 65h + 150

The third blank or tab is -0.9, -0.25, 0.25, or 0.9
What answers are they?
Answer:
Answer: first one is -1 and 0
Second one is: zero falls between the values of f(x) for these inputs
Third one is: -0.9
Step-by-step explanation:
A zero can be found between the input values of -1 and 0 because zero falls between the values f(x) for these inputs.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Cubic functions are functions of the form,
f(x) = ax³ + bx² + cx + d = 0
We have input values and output values for those input values for the cubic function.
A zero of the function is the value of the input when output value equals zero.
When x = -1, f(x) = -0.5
When x = 0, f(x) = 2.5
The value of f(x) = 0 between these input values.
One zero of the function is approximately -0.9, which is more approximate.
Hence the zero of the function lies between -1 and 0.

What is the probability of at least 2 people having the same birthday as you in a class of 29 students?
Answer:
The chance that the second person has the same birthday is 1/365. To find the probability that both people have this birthday, we have to multiply their separate probabilities. (365/365) * (1/365) = 1/365, or about 0.27%

The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?
The value of x is 48°. Therefore, the answer is (A) 48.
We can solve for the value of x using the properties of parallel lines and transversals.
**Given:**
* Two parallel lines cut by a transversal.
* Two alternate exterior angles formed by the transversal on the parallel lines:
* **2x + 2°**
* **x + 50°**
**Solving for x:**
1. **Alternate Interior Angles:** We know that alternate interior angles formed by a transversal cutting parallel lines are congruent. Therefore:
- 2x + 2° = x + 50°
2. **Solve for x:**
- Combine like terms: x + 2° = 50°
- Subtract 2° from both sides: x = 48°
Therefore, the value of x is **48°.**
Therefore, the answer is (A) 48.
The probable question may be:

what is the answer to -4/3p -2/5
Answer:
Step-by-step explanation:
This expression consists of two fractions that have no common denominator but do have -2 as a common factor in the numerators.
Factoring out the -2, we get:
-2(2p/3 + 1/5)
If you want to go further, we can determine the LCD (which is 15) and then combine the fractions within parentheses:
-2(10p/15 + 3/15)
We could now factor out the 1/15 in each fraction:

Mattie Evans drove 180 miles in the same amount of time that it took a turbopropeller plane to travel 630 miles. The speed of the plane was 150 mph faster than the car.
Answer:
the speed of the plane was 210 mph.
Step-by-step explanation:
Final answer:
The speed of Mattie Evans' car was 60 mph and that of the plane was 210 mph.
Explanation:
The question involves solving a system of equations to find the speeds of the car and the plane. Since Mattie Evans drove 180 miles in the same amount of time that a turbopropeller plane traveled 630 miles, and the speed of the plane was 150 mph faster than the car, we can set up the equations based on the distance formula
[tex]distance = speed \times time.[/tex]
Let the car's speed be x mph. The plane's speed then will be x + 150 mph.
The time taken by both the car and the plane is the same. Therefore, we can say 180/x = 630/(x + 150).
By cross-multiplying the equation, we obtain
180(x + 150) = 630x.
Simplifying the equation, we have
180x + 27000 = 630x.
630x-180x = 27000
450x = 27000
x = 27000/450
x = 60
The speed of Mattie Evans' car was 60 mph and that of the plane was 210 mph (60+150).

Answer:
No solution or
(-3±[tex]2i\sqrt{31}[/tex])/8
Step-by-step explanation:
To get the solution, move everything to the left side of the equation:
8x²+6x+5 = 0
If you try to factor the equation or graph it, you will see that it will never equal 0.
If you need an imaginary solution you can plug it into the quadratic equation:
-6±[tex]\sqrt{36-160}[/tex] over 16
Simplify and you get
-6±[tex]i\sqrt{124}[/tex] over 16
-6±[tex]4i\sqrt{31}[/tex] over 16
Simplify the fraction and you can get
(-3±[tex]2i\sqrt{31}[/tex])/8

Prove that the angle pqr is a right angle
Pls show full working out ty
Answer:
A missing bit of information is that ABCD must be a rectangle.
First, let's gather some facts:
(1) Angles in a triangle add up to 180.
(2) RQC and PBQ are the same triangles since it is given that their sides are equal.
(3) Also ∠PBQ = ∠QCR are 90° since they are in fact the corners of the rectangle.
(4) ∠PQB, ∠PQR and∠RQC are on the same line, so their sum must be 180°
Putting it all together, we can say for both triangles using (1):
∠RQC + ∠QRC + ∠QCR = 180 and ∠QCR=90 => ∠RQC = 90-∠QRC
∠PBQ + ∠BQP + ∠PQB = 180
Furthermore, since both triangles are equal (2):
∠QRC = ∠PQB
So, ∠RQC = 90 - ∠PQB
Finally, using (4) we can say:
∠PQB + ∠PQR + 90 - ∠PQB = 180.
Simplify that and you get:
∠PQR + 90 = 180
∠PQR = 90
How do you factor 6x2 + 11x + 3
Answer:
(3x + 1) (2x + 3)
These are the factors of 6x2 + 11x + 3
Step-by-step explanation:
Math Term Definition. Factor. To factor a number means to break it up into numbers that can be multiplied together to get the original number. EXAMPLES: 6 = 3 x 2 so, factors of 6 are 3 and 2 9 = 3 x 3 so, factors of 9 are 3 and 3 Sometimes, numbers can be factored into different combinations.
Write 4.135 as a fraction
The fraction is 4135/1000.
To write the decimal number 4.135 as a fraction, we first observe that the digits 135 are in the thousandths place. Therefore, we can express the decimal as the fraction 4135/1000. This is because the decimal has three decimal places, and each place value to the right of the decimal point represents a power of ten.
When there's an interest in scientific notation, converting fractions into scientific notation may also be required. As an example, a tiny fraction like 0.0000045 would be written in scientific notation as 4.5 * 10^{-6}.
However, the question asks for a simple fraction, not scientific notation. Therefore, 4.135 as a fraction is simply 4135/1000.
The number 4.135 can be written as a fraction in the form of [tex]\frac{4135}{1000}[/tex]. In scientific notation, it can be expressed as 4.135 x [tex]10^{-3}[/tex], as moving the decimal point 0 places leaves the number unchanged.
To write the number 4.135 as a fraction, you first need to recognize that it is the same as 4135 divided by 1000 since there are three digits after the decimal point. Therefore, the fraction form of 4.135 is [tex]\frac{4135}{1000}[/tex]. This fraction can be simplified if desired by dividing both the numerator and the denominator by the greatest common divisor.
In scientific notation, the number 4.135 can be expressed as 4.135 x [tex]10^{-3}[/tex], because the power of 10 that keeps the number in its original form here is 0. Remember that scientific notation is written as a product of a number between 1 and 10 and a power of 10, where the power indicates how many places the decimal point is moved to the right (for positive powers) or to the left (for negative powers). Because the number is more than 1 but less than 10, we can keep it as is with a power of 10 that is 0.
