Answer: x = 0; x = 3
Step-by-step explanation:
x^2 - 3x = 0
1. x is a common factor, so factor it out
x(x - 3) = 0
2. set both factors equal to zero
x = 0
x - 3 = 0
3. final answer
x = 0
x = 3

Yes, because the slopes of the equations are different so the system of equations will have one solution.
No, because the slopes of the equations are different so the system of equations will have no solutions.
Yes, because the slopes of the equations are the same so the system of equations will have infinitely many solutions.
No, because the slopes of the equations are the same so the system of equations will have no solutions.
Answer:
Yes, because the slopes of the equations are different so the system of equations will have one solution.

You have 200 feet of fencing to build a rectangular dog pen. If you want the pen to have the maximum possible area. What should the dimensions of the pen be? Show your work.
Answer:
Each side would be 50 ft
Step-by-step explanation:
200/4=50
50*50=2,500
Techinally this is a square so if they really want it to be a "rectangle" it would be 51 and 49 and the areas would be 2,499...but the answer should be 50
Se quiere realizar la adición y multiplicación de los números enteros 43 y -32. En relación con los signos de las operaciones se puede decir que
Answer:
El caso de la adición es trivial.
La adición entre los números A y B es:
A + B
Entonces la adición entre los números 43 y -32 es:
43 + (-32)
No hace falta realizar la suma para darnos cuenta de que el resultado tendra signo positivo, esto se da porque el módulo del número positivo es mayor que el del número negativo.
Así tenemos:
43 + (-32) = 43 - 32 = 11
Para el caso de la multiplicación podemos recordar:
(+)*(+) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
(-)*(-) = (+)
Entonces el producto entre un número positivo y uno negativo (como es nuestro caso con 43 y -32) siempre tendrá un signo negativo.
Entonces podemos concluir que el signo de la multiplicación entre esos dos números va a ser negativo.
También podemos resolver la multiplicación de otra forma para ver esto:
43*(-32)
43*( (-1)*32)
43*(-1)*(32)
(-1)*(43*32)
Que es claramente un número negativo.

The height of a cylinder is twice the radius of its base
Answer:
2πr³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ← r is the radius and h the height
Here h = 2r, hence
V = πr² × 2r = 2πr³
Answer:
yes

Samantha has 52 jelly beans. She decides that she will eat 4 jelly beans per minute, and she wants to create an expression that represents how many jelly beans she has left after x minutes. Which of the following expressions correctly models this situation?
Select one:
A. 4x + 52
B. x + 52
C. -x + 52
D. -4x + 52
~and also if whoever answers doesn't mind, please put an actual explanation since I just wanna be able to fully understand the concept! It would be greatly appreciated! ~
Answer:
-4x+52
Step-by-step explanation:
So we know that Samantha has 52 jelly beans and that she'll eat 4 jelly beans per minute in X minutes.
It'd be 4*x=4x
Usually, it'd be 52-4x
But you can create an equivalent
Lets say x=5
So she'd eat 20 jelly beans
52-20=32
BUT
-20+52=32

A group of four friends went out for dinner. Their bill came to $50.95. They also need to pay 8% sales tax, and want to tip their server 18% on the cost of the meal (including tax). How much will EACH friend have to pay? Round your answer to the nearest cent.
Answer:
Enter cost and tip percent to get a tip amount and total dinner amount. Also split the total amount; divide among any number of people. ... Money, Pay, Taxes. > Tip ... Enter your meal or dinner cost along with the tip percentage. ... To calculate a gratuity or tip on any calculator it is a simple multiplication. ... All rights reserved
Step-by-step explanation:
After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8%. You decide to leave a 20% tip for the waiter based on the pre-tax amount. How much ... To figure out the tip, you need to find 20% of $52.60. 0.2 \times 52.6
The amount that each person should pay is $22.06 .
What is percent?Percentages can be stated as essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. We can take as example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
here, we have,
in the question ,
it is given that
total number of persons = 3 person + 1 = 4 persons
cost of the meal = $72.50
sales tax percent = 6.75%
tip percent = 15%
So , the amount of sales tax = 6.75% of cost = 0.0675 * 72.50 = $4.89
and , the amount of tip is = 15% of cost
= 0.15 * 72.50
= 10.87
So , the total amount payable is = cost + sales tax + tip
= 72.50 + 4.89 + 10.87
= 88.26
since the total number of persons is 4 ,
the amount per person is = 88.26/4 = 22.06
Therefore , The amount that each person should pay is $22.06 .

here is a triangle prism
why is the surface area of the prism, in square centimeters?
Answer:
Step-by-step explanation:
(6 * 4) + 2(10 * 5) + (10 * 6)
Multiply 6 by 4 to get 24.
24 + 2(10 * 5) + (10 * 6)
Multiply 10 by 5 to get 50, then multiply by 2 to get 100.
24 + 2(50) + (10 * 6)
24 + 100 + (10 * 6)
Multiply 10 by 6 to get 60.
24 + 100 + 60
Add 24 to 100 to get 124.
124 + 60
Add 124 to 60 to get 184.
184 cm²
The surface area of the prism is 184 cm².
