Sam is baking cakes at her parent’s bakery. She gets paid 20 a week in addition to 5 for every cake she bakes. She made 50 this week. Write an equation to show how many cakes Sam baked this week

Answers

Answer:

i think it is 20 + 5x = 50    or  f(x)=2(3^x)

Step-by-step explanation:

equation to show how many cakes sam baked this week:

20 + 5x = 50

20 = 20 dollars

5 = 5 more dollars

x = number of cakes

therefore, sam earned $50 this week.

Answer:

20+5x=50

x will represent the number of cakes she baked

she gets paid $5 for every cake she bakes, this is where the 5x comes from

she makes $20 ("in addition" that's where the "+20" comes from) a week. However, in this case we're only talking about what she made in one week, hense why there is no variable attached to the 20

she makes a total of $50

20+5=50

she baked a total of 6 cakes. How?

subtract 20 from both sides so you have:

5x=30

divide both sides by 5 to get x by itself:

x=6

each hour of the party. How long was the party?
A.. 3 hours
B.. 4 hours
C.. 5 hours
D.. 6 hours

Answers

Answer:

The party was 4 hours long.

Step-by-step explanation:

Subtract the total by the amount already known was spent directly.

320.91-200.39= 120.52

Now, in order to figure out how many hours the part was, take how much each hour and divide it by the remainder of money.

Thus, 120.52/30.13 = 4

A reporter determines a baseball player’s batting average, which is a ratio of the number of hits to number of times at bat. The result is shown on a calculator as 0.212121....Write this repeating decimal as a fraction.

Answers

Answer:

21/99 or 7/33

Step-by-step explanation:

x = 0.212121

Then we multiple the decimal and x by hundred.

100x = 21.212121

Then we subtract the 21.212121 by 0.212121.

100x = 21.212121 - 0.212121

But when you are subtracting 100x, you need to subtract 100x by x because in the first step it said x = 0.212121.

100x - x = 21.212121 - 0.212121

You will have at the end is

99x = 21

Divide 99 on both side and you left with

21/99 or 7/33 simplified version

Select the statement that correctly completes the sentence. When using more than one adjective, ________.

A. size comes after color
B. size comes after shape
C.size comes before color
D. size comes before opinion

Answers

Answer:

more comfortable

Step-by-step explanation:

Final answer:

When using more than one adjective, 'size comes before color', which is option C. Adjectives in English typically follow an established order, with the size adjective placed before the color adjective.

Explanation:

The correct statement that completes the sentence when using more than one adjective is C. size comes before color. In English, adjectives follow a specific order in which they appear before a noun. This order is generally: opinion, size, shape, age, color, origin, material, and purpose. Therefore, size should be placed before color when describing a noun with multiple adjectives.

For example, when arranging adjectives in a sentence, the phrase would be 'a small green book' rather than 'a green small book'. The adjective 'small' represents the size and 'green' represents the color, and according to the correct adjective order, size should come before color.

Does a dilation produce a congruent figure

Answers

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. ... If the scale factor is 1, the figure and the image are congruent. The word "dilate" is often heard in relation to the human eye.

After dilation, the size of the new image is not the same as the original. Therefore, dilation cannot produce a congruent figure.

Recall:

When two figures are congruent, it means they have the same shape and size, whereby, all pairs of corresponding angles and sides of both figures are congruent or equal in measure.The image attached below shows a dilated figure.

Dilation is a transformation that enlarges a figure or reduces the figure.

After dilation, the new figure maintains the same shape of the original figure.

However, after dilation, the size of the new image is not the same as the original. Therefore, dilation cannot produce a congruent figure.

For the first parametric functions the cartisian function is y = 5+ 0.84x - 0.7x², and for the second parametric function the cartisian function is y = 2/x where x>0

What are parametric equations?

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

For the first parametric functions:

[tex]\rm x(t)=23t \\\\y(t)=5+19.3t-16t^2[/tex]

[tex]\rm t = \dfrac{x}{23}[/tex]

Put this value in the y(t)

[tex]\rm y=5+19.3(\dfrac{x}{23})-16(\dfrac{x}{23})^2[/tex]

y = 5+ 0.84x - 0.7x²

For the second parametric functions

[tex]\rm x(t)=e^t .....(1)\\\\y(t)=2e^-^t[/tex]

Taking ln in equation (1)

lnx = t

Put this value in equation (2)

[tex]\rm y=2e^{-lnx}[/tex]

y = 2/x,   x>0

Thus, for the first parametric functions the cartisian function is y = 5+ 0.84x - 0.7x², and for the second parametric function the cartisian function is y = 2/x where x>0

Daniel has read 60​% of a book. He has 28 more pages to finish. How many pages are there in the​ book? There are nothing pages in the book.

Answers

The total number of pages in Daniel's book is 70 pages.

Given that Daniel has read 60% of it and that he has 28 pages left to finish it. The remaining 28 pages represent the

40% of the book that Daniel has not read yet.

We can set up the equation where 40% of the total page number (represented as x) equals 28 pages.

0.40x = 28

x = 28 / 0.40

x = 70

There are 70 pages in the book.

To find the total number of pages in the book, we'll start by setting up an equation based on the information provided. Let's denote the total number of pages in the book as x.

Daniel has read 60% of the book, leaving 40% unread. Given that he has 28 more pages to finish, we can express this information in an equation:

0.40x = 28

This equation represents the 40% of the book that Daniel has yet to read, which equals the 28 pages remaining.

To find the total number of pages ( x ), we divide both sides of the equation by 0.40:

[tex]\[ x = \frac{28}{0.40} \][/tex]

x = 70

So, there are 70 pages in the book. This solution implies that there are 70 pages, considering that "nothing" is simply a placeholder value and doesn't affect the calculation.

Use the net to find the surface area of the rectangular prism. A) 168 units2 B) 192 units2 C) 220 units2 D) 224 units2

Answers

Answer:

See below.

Step-by-step explanation:

You didn't provide any dimensions to test the answers with, but here is how you could solve the problem.

A rectangular prism is just an oblong cardboard box basically. Think about how you would unfold that box. It would be made up of 3 pairs of rectangles (2 end pieces, the top and bottom, and 2 sides). To calculate its surface area you just calculate the areas of each piece and add them up.  

The overall formula ends up being:

Area = 2(LW) + 2(LH) + 2(WH)

Without drawing the graphs, find the points of intersection of the lines:

11x–6y=2 and –8x+5y=3


PLZZZZZZZ HELP!

Answers

The point of intersection of the lines given by the equations [tex]\( 11x - 6y = 2 \) and \( -8x + 5y = 3 \) is \( (4, 7) \).[/tex]

To find the points of intersection of the given lines, we need to solve the system of linear equations simultaneously.

 The given equations are:

[tex]\[ 11x - 6y = 2 \quad \text{(Equation 1)} \][/tex]

[tex]\[ -8x + 5y = 3 \quad \text{(Equation 2)} \][/tex]

 We can solve this system using the method of substitution or elimination. Let's use the elimination method to find the values of [tex]\( x \)[/tex]and [tex]\( y \).[/tex]

 First, we will make the coefficients of [tex]\( y \)[/tex] the same in both equations by multiplying Equation 1 by 5 and Equation 2 by 6:

 [tex]\[ 5(11x - 6y) = 5(2) \][/tex]

[tex]\[ 6(-8x + 5y) = 6(3) \][/tex]

 This gives us:

[tex]\[ 55x - 30y = 10 \quad \text{(Equation 3)} \][/tex]

[tex]\[ -48x + 30y = 18 \quad \text{(Equation 4)} \][/tex]

 Now, we add Equation 3 and Equation 4 to eliminate [tex]\( y \):[/tex]

[tex]\[ (55x - 30y) + (-48x + 30y) = 10 + 18 \][/tex]

[tex]\[ 7x = 28 \][/tex]

 Dividing both sides by 7, we get:

[tex]\[ x = 4 \][/tex]

 Now that we have the value of [tex]\( x \)[/tex], we can substitute it back into either Equation 1 or Equation 2 to find the value of [tex]\( y \)[/tex]. Let's use Equation 1:

[tex]\[ 11(4) - 6y = 2 \][/tex]

[tex]\[ 44 - 6y = 2 \][/tex]

 Subtracting 44 from both sides, we get:

[tex]\[ -6y = -42 \][/tex]  Dividing both sides by -6, we get:

[tex]\[ y = 7 \][/tex].

c. x^2=10y-25
d. y^2=25-10x

Please select the best answer from the choices provided

A
B
C
D

Answers

Final answer:

By applying polar to rectangular coordinates conversion formulas, the polar equation r = 5/(1+cos(θ)) is equivalent to the rectangular coordinate equation y² = 25 - 10x, which matches option D.

Explanation:

To convert the polar equation r = 5/(1+cos(θ)) to rectangular coordinates, we use the relationships between polar and rectangular coordinates: r = √x² + y² and cos(θ) = x/r. Substituting these into the given equation, we get:

r = √x² + y²;

cos(θ) = x/r;

r(1+cos(θ)) = 5;

r + r x/r = 5;

r + x = 5;

r = 5 - x;
Substitute back in for r, we get:

(√x² + y²) = 5 - x;
Squaring both sides gives us x² + y² = (5 - x)² which can be simplified to x² + y² = 25 - 10x + x². Canceling x² from both sides and reordering the terms gives us y² = 25 - 10x, which matches option D.
