Alejandra tiene una cubeta de 1 1/2 litros de pintura que le sobraron de su último mural. Para no cargar toda la cubeta, ella dividirá la pintura en frascos de 1/4 de litro. ¿Cuántos frascos necesitará?
Answer:
The correct answer is 6 jars can be used
Step-by-step explanation:
According to the given scenario, the calculation of the number of jars needed is shown below:
The 1 1 ÷ 2 liters means = 3 ÷ 2 liters
And, the paint is divided into 1 ÷4 liter jars
So, the number of jars needed is
= (3 ÷ 2) ÷ ( 1 ÷ 4)
= (4 × 3) ÷ 2
= 6 jars needed
Therefore the number of jars needed is 6 jars

Answer:
(7, - 3 ) and (- [tex]\frac{5}{3}[/tex], [tex]\frac{17}{3}[/tex] )
Step-by-step explanation:
Given the 2 equations
y = 4 - x → (1)
x² + 2y² = 67 → (2)
Substitute y = 4 - x into (2)
x² + 2(4 - x)² = 67 ← expand and simplify left side
x² + 2(16 - 8x + x²) = 67
x² + 32- 16x + 2x² = 67
3x² - 16x + 32 = 67 ( subtract 67 from both sides )
3x² - 16x - 35 = 0 ← in standard form
(x - 7)(3x + 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - [tex]\frac{5}{3}[/tex]
Substitute these values into (1) for corresponding values of y
x = 7 : y = 4 - 7 = - 3 ⇒ (7, - 3 )
x = - [tex]\frac{5}{3}[/tex] : y = 4 + [tex]\frac{5}{3}[/tex] = [tex]\frac{17}{3}[/tex] ⇒ (- [tex]\frac{5}{3}[/tex], [tex]\frac{17}{3}[/tex] )
solutions are (7, - 3 ) and (- [tex]\frac{5}{3}[/tex], [tex]\frac{17}{3}[/tex] )
The solution of the equations are [tex]x=7[/tex] and [tex]x=-1.67[/tex]
System of equations:The given system of equations are,
[tex]y=4-x\\\\x^{2} +2y^{2} =67[/tex]
Substitute value of y in second equation;
[tex]x^{2} +2(4-x)^{2} =67\\\\x^{2} +2(16+x^{2} -8x)=67\\\\x^{2} +32+2x^{2} -16x=67\\\\3x^{2} -16x-35=0\\\\x=\frac{16\pm\sqrt{256+420} }{6}\\ \\x=7, -1.67[/tex]

Find the range of the function for the domain {−3, 1, 4.5}. f(x) = 2x^2
Answer:
D.
Step-by-step explanation:
The domain can be understood as being the x whereas the y can be considered as being the range.
We know that in order to find the y, or in order words [tex]f(x)[/tex] we can simply plug in any x value that we're interested in into [tex]f(x) = 2x^{2}[/tex]
If we do that with the values of x (or domain) that we have from the problem, we will get
[tex]f(-3) = 2\cdot (-3)^2 \\f(-3) = 18\\\\f(1) = 2\cdot 1^2\\f(1) = 2\\\\f(4.5) = 2\cdot 4.5^2\\f(4.5) = 40.5\\[/tex]
From the results that we got, we know that the answer is D.
Good luck!
Answer:
D
Step-by-step explanation:
f(x) = 2x^2
f(3) = 2*(-3)^2
f(3) = 2* 9
f(3) = 18
=======
f(1) = 2*(1)^2
f(1) = 2*1
f(1) = 2
=========
f(4.5) = 2*4.5^2
f(4.5) = 2 * 20.25
f(4.5) = 40.5

Answer: The most number of skeins Sharon can afford to buy is 3.
Step-by-step explanation:
Step-by-step explanation:
Consider the provided information.
Sharon has at most $25 to spend on her sister's birthday gift.
That means Sharon can spend not more than $25.
She already bought a knitting machine for her, which cost $14.99.
She would also like to get her sister some skeins of yarn to go with it. Each skein costs $2.75.
Let y represent the number of skeins of yarn.
Thus, the required inequality is:
Now solve the above inequality.
Skeins must be an integer.
Hence, the most number of skeins Sharon can afford to buy is 3.

Greg has tickets to six of the team’s games this season. He is designing a simulation, using last year’s wins and losses, to predict whether the team will win or lose each of the games he attends.
Which tool is most appropriate for use in a simulation that fits the data?
a coin with one side representing a win and the other representing a loss
a 6-section spinner with congruent sections, 4 representing a win and 2 representing a loss
a 5-section spinner with congruent sections, 3 representing a win and 2 representing a loss
an 8-sided die with 5 sides representing a win and 3 sides representing a loss
Answer:
a coin with one side representing a win and the other representing a loss
Step-by-step explanation:
Answer:
C: a 5-section spinner with congruent sections, 3 representing a win and 2 representing a loss
Step-by-step explanation:
edg2021
You simply have to simplify. 24 wins and 16 loses is equal to 3 / 2. So it is C.
It is not A (to the person who said it was a coin) and that is because it is not equal. There are more wins than losses.

Digit thinks that the graphs of exponential and logarithmic functions are more alike than they are different.
What do you think he means by that?
Be sure to express your thoughts clearly and use correct mathematical language in your explanation.
Answer:
Definitions
At the most basic level, an exponential function is a function in which the variable appears in the exponent. The most basic exponential function is a function of the form y=bx where b is a positive number.
When b>1 the function grows in a manner that is proportional to its original value. This is called exponential growth.
When 0>b>1 the function decays in a manner that is proportional to its original value. This is called exponential decay.
Graphing an Exponential Function
Example 1
Let us consider the function y=2x when b>1. One way to graph this function is to choose values for x and substitute these into the equation to generate values for y. Doing so we may obtain the following points:
(−2,14), (−1,12), (0,1), (1,2) and (2,4)
As you connect the points, you will notice a smooth curve that crosses the y-axis at the point (0,1) and is increasing as x takes on larger and larger values. That is, the curve approaches infinity as x approaches infinity. As x takes on smaller and smaller values the curve gets closer and closer to the x-axis. That is, the curve approaches zero as x approaches negative infinity making the x-axis is a horizontal asymptote of the function. The point (1,b) is on the graph. This is true of the graph of all exponential functions of the form y=bx for x>1.
