6). To make trail mix you need 2
cups of raisins for every 3 cups
of almonds. How many cups of
raisins are needed for 12
cups of almonds?

Answers

Answer:

[tex]\boxed {\boxed {\sf 8 \ cups \ of \ raisins }}[/tex]

Step-by-step explanation

Let's create a proportion using this setup.

[tex]\frac{raisins}{almonds} =\frac{raisins}{almonds}[/tex]

We know that 2 cups of raisins are needed for 3 cups of almonds.

[tex]\frac{2 \ cups \ raisins}{3 \ cups \ almonds} =\frac{raisins}{almonds}[/tex]

We don't know how many cups of raisins are needed for 12 cups of almonds. Therefore, x cups of raisins are needed for 12 cups of almonds.

[tex]\frac{2 \ cups \ raisins}{3 \ cups \ almonds} =\frac{x \ cups \ raisins}{12 \ cups \ almonds}[/tex]

[tex]\frac{2 }{3} =\frac{x }{12 }[/tex]

Since we are solving for x, we must isolate that variable. It is being divided by 12. The inverse operation of division is multiplication. Multiply both sides of the proportion by 12.

[tex]12*\frac{2 }{3} =\frac{x }{12 }*12[/tex]

[tex]12*\frac{2 }{3}=x[/tex]

[tex]8=x[/tex]

8 cups of raisins are required for 12 cups of almonds.

Which set of steps will translate f(x) = 6X to g(x) = 6x – 5 – 7?
Shift f(x) = 6* five units to the left and seven units up.
O Shift f(x) = 6' five units to the right and seven units down.
Shift f(x) = 6X seven units to the right and five units up.
Shift f(x) = 6X seven units to the left and five units down.

Answers

Answer:

5 left 7 down

Step-by-step explanation:

The correct set of steps to translate f(x) = 6ˣ to g(x) = 6ˣ⁻⁵ – 7 is to shift f(x) = 6ˣ  five units to the right and seven units down.

What is a transformation?

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The functions are given in the question, as follows:

f(x) = 6ˣ and g(x) = 6ˣ⁻⁵ – 7

Consider the graph of f(x) = 6ˣ.

Shifting the graph seven units to the right means that each x-coordinate of a point on the graph will be decreased by five. This will result in a horizontal shift to the right of the graph.

Shifting the graph seven units down means that each y-coordinate of a point on the graph will be decreased by seven. This will result in a vertical shift downward of the graph.

Therefore, the new equation of the translated graph will be g(x) = 6ˣ⁻⁵ - 7.

Nancy and Linda go to their favorite restaurant. Nancy has a $5 off coupon to use for her purchase of $30. Linda has a 10% off coupon to use for her purchase of $25. What is the difference between the total the friends will pay individually

Answers

Answer:

Step-by-step explanation:

2.50

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

If Nancy has to buy an item that cost $30 with a 5% off and Ninda has to buy an item that cost $25 with a 10% off.

The difference between individual pay is $6.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Nancy:

Coupon = 5% off

Cost of the purchase = $30

Amount to pay:

= 30 - (5/100) x 30

= 30 - 30/20

= 30 - 1.5

= $28.5

Linda:

Coupon = 10% off

Cost of the purchase = $25

Amount to pay:

= 25 - (10/100) x 25

= 25 - 2.5

= $22.5

The difference between individual pay:

= 28.5 - 22.5

= $6

Thus

The difference between individual pay is $6.

What is 24 − 6 × 3 + 52 − (16 ÷ 2)?

Answers

Answer:

23

Step-by-step explanation:

When answering expressions like these we should always go by the order of operation. That order tells us to do parentheses, exponents, multiplication/division, then addition/subtraction. So as it said we will do whatever is inside the parentheses which is 16 ÷ 2.

24 − 6 × 3 + 5^2 − (16 ÷ 2)

24 − 6 × 3 + 5^2 − 8

Next is the exponent.

24 − 6 × 3 + 5^2 − 8

24 − 6 × 3 + 25 − 8

Now we will do multiplication/division.

24 − 6 × 3 + 25 − 8

24 − 18 + 25 − 8

Lastly we'll do addition/subtraction.

24 − 18 + 25 − 8

6 + 25 - 8

31 - 8

23

And that's it we got it!

24 - 6 x 3 + 52 - (16/2)= 50 !

Find the Error A student solved the equation and determined that the solution was –2. Choose the response that shows her error and corrects it.




Multiple choice question.

A)
There is no error, her answer is correct.


B)
The initial equation simplifies to 3x = 0, which means that x = 0.


C)
The equation –2 = –2 is always true, so no value of x will make the equation true. The correct solution of the equation is that there is no solution.


D)
The equation –2 = –2 is always true, so every value of x will make the equation true. The correct solution of the equation is infinitely many solutions.

Answers

The equation –2 = –2 is always true, so no value of x will make the equation true. The correct solution of the equation is that there is no solution.

What is equation?

In mathematics, an equation is a statement that shows the equality between two expressions. It contains an equals sign (=) that separates the two expressions. The expressions on both sides of the equals sign can be numbers, variables, or functions. The equation represents a relationship between the expressions that must hold true for all values of the variables involved. Solving an equation means finding the values of the variables that satisfy the equation. Equations are used in various fields, such as physics, engineering, economics, and many others, to model and solve real-world problems.

Here,

The error made by the student is assuming that -2 is the solution to the equation without actually solving it. The equation -2 = -2 is always true, which means that the equation is an identity and has no solution. So, the correct solution of the equation is that there is no solution.

The power of 5 of complex number z is (-16√3 + 16) + 4(-√3 + 3)i

What is a complex number?

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

z = 1 + √3i

We have to find: z⁵

z⁵ = (1 + √3i)(1 + √3i)(1 + √3i)(1 + √3i)(1 + √3i)

z⁵ = (-2 + 2√3)(1 + √3i)(1 + √3i)(1 + √3i)

[tex]\rm z^5=\left(2\sqrt{3}-2\right)+2\left(3-\sqrt{3}\right)i(1+\sqrt{3}i)(1+\sqrt{3}i)[/tex]

[tex]\rm =\left(-4\sqrt{3}+4\right)+4\left(3-\sqrt{3}\right)i(1+\sqrt{3}i)[/tex]

z⁵ = (-16√3 + 16) + 4(-√3 + 3)i

Thus, the power of 5 of complex number z is (-16√3 + 16) + 4(-√3 + 3)i

Enter values to complete each statement below based on the graph.

Answers

Answer:

1 gallon of paint will paint 400 ft² of the wall

Unit rate = 400 ft² per gallon

Step-by-step explanation:

From the graph, when 1 gallon of paint was used, (x = 1), an area of 400 ft² of the wall was painted (y = 400).

Unit rate = y/x. That is, the amount of square feet of wall that would be painted using 1 gallon of paint.

Unit rate = 400 ft²/1 gallon = 400 ft²/gallon.
