Mr. Smith drove for 45 minutes at a speed of 40 km/h. He stopped for 15 minutes for a coffee break and then he drove for 2 hours at a speed of 75 km/h. What was his average speed for the entire journey?
Answers
Answer:
60 km/h
Step-by-step explanation:
Average speed is total distance over total time.
Total distance: 30 + 0 + 150 = 180 km.
Total time: 0.75 + 0.25 + 2 = 3 hrs.
180/3 = 60/1
What are the excluded values of x for
Answers
Answer:
x = - 2, x = 9
Step-by-step explanation:
Given
f(x) = [tex]\frac{x^2-9x}{x^2-7x-18}[/tex]
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0
(x - 9)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 9 = 0 ⇒ x = 9
The excluded values are x = - 2, x = 9
If Charlie had 28 grapes and Tristan has 23 grapes how many grapes do they have in total
Answers
Answer:
51
Step-by-step explanation:
28 + 23 = 51
Answer:

3x^2(x - 5) + 8(x - 5)
Which is the completely factored form of her polynomial?
O (3x^2 – 5) (X + 8)
O (3x^2 – 8) (x + 5)
O (3x^2 + 8) (x - 5)
O (3x^2 + 5) (x – 8)
Answers
Answer:
its (3x²+8)(x-5)
Step-by-step explanation:
3x² * x = 3x³.
3x² * -5 = -15x².
8 * x = 8x.
8 * -5 = -40.
The completely factored form of her polynomial is (3x² + 8)(x - 5).
What is the factoring of a polynomial?"Factorization of polynomials expresses a polynomial with coefficients in a given field or in the integers as the product of irreducible factors with coefficients in the same domain."
Given polynomial is:
3x³ – 15x² + 8x - 40
= 3x²(x - 5) + 8(x - 5)
= (3x² + 8)(x - 5)

If Ben saves $15 a week for the next 10 weeks, will he be able to buy the stereo and why?
No, because he needs to save at least $153, and he will only save $150 over the next ten weeks.
No, because he needs to save $577, and he will only save $150 more.
Yes, because he has already saved $365, and the stereo cost $212.

Item 6 Graph △JKL and its image after a reflection in the y-axis. J(5, 3), K(1,−2), L(−3, 4)
Answers
Answer:
J(-5,3) K(-1,-2) L(3,4)
Step-by-step explanation:
Reflections over the y axis make the x its opposite. 5 would change to -5, 1 would change to -1, and -3 would change to 3.
When a shape is reflected, it must be reflected across a line.
See attachment for the graph of the image of JKL
The coordinates are given as:
[tex]\mathbf{J = (5,3)}[/tex]
[tex]\mathbf{K = (1,-2)}[/tex]
[tex]\mathbf{L = (-3,4)}[/tex]
The rule of reflection across the y-axis is:
[tex]\mathbf{(x,y) \to (-x,y)}[/tex]
So, the image of the reflection is:
[tex]\mathbf{J'= (-5,3)}[/tex]
[tex]\mathbf{K'= (-1,-2)}[/tex]
[tex]\mathbf{L'= (3,4)}[/tex]

On the first night, the Movie House Theater sold 7 adult tickets and 11 child tickets for
$227. On the second night they took in $150 by selling 6 adult tickets and 6 child tickets.
Find the price of an adult ticket and the price of a child ticket.
Answers
Answer:
Adults $10
Child: $6
Step-by-step explanation:
I took the test
The price of an adult ticket and the price of a child ticket are $12 and $13.
What is the system of equation?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
On the first night,
the Movie House Theater sold 7 adult tickets and 11 child tickets for $227.
On the second night, they took in $150 by selling 6 adult tickets and 6 child tickets.
Let x be the number of tickets sold to an adult and y be the number of tickets sold to a child.
According to the question,
7x + 11y = 227 equation 1
and 6x + 6y = 150,
Simplifying,
x + y = 25 equation 2
Now, we have a system of equations.
7x + 11y = 227 equation 1
x + y = 25 equation 2
From the equation 2 we have,
y = 25 - x
Substitute the value of y to the equation 1,
7x + 11(25-x) = 227
7x + 275 - 11x = 227
275 - 227 = 4x
x = 48/4
x = 12
Then y = 25 - 12
y = 13.
Therefore, the prices of ticket for adult's and children are $12 and $13 respectively.
