Jessica paid more than Amber at lunch.

To find out, we first need to calculate the amount of tip each person left:

Amber's tip = 11.70 x 0.18 = $2.11

Jessica's tip = 12.30 x 0.15 = $1.85

Then we add the cost of the lunch and the tip for each person:

Amber's total cost = 11.70 + 2.11 = $13.81

Jessica's total cost = 12.30 + 1.85 = $14.15

So Jessica paid $0.34 more than Amber for lunch.

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Step-by-step explanation:

If x is the pounds of apples, 2x is pounds of peaches, and 3x is pounds of bananas, then the total cost is:

4(x) + 5(2x) + 2(3x) = 10

4x + 10x + 6x = 10

20x = 10

x = 0.5

Kelly buys 0.5 pounds of apples, 1 pound of peaches, and 1.5 pounds of bananas, for a total of 3 pounds of fruit.

Answer:

the surface area of the rectangular prism is found as : S = 275 ¹/₈ cm².

Length l = 11 ³/₄ cm = 47/4 cm = 11.75 cm

width w = 5 ³/₄ cm = 23/4 cm = 5.75 cm

height h = 4 cm

surface area of the prism S = 2(lw + wh + hl)

S = 2(11.75*5.75 + 5.75*4 + 4*11.75)

S = 2*137.5625

S = 275.125

S = 275 ¹/₈ cm²

Part A:

x > 13

Part B:

How to show this inequality on a number line is a closed circle on 13, going left of 13.

Step-by-step explanation:

Part A:

x represents the age of children who are allowed to operate the boat.

Our inequality is < because if you are of the age of 13 you are allowed to operate the boat,

the inequality x > 13 reads x (the age of children) is greater than or equal to 13

Part B:

How to describe inequalities on a number line;

Closed circle: less than or equal to - or - greater than or equal to ( < , > )

Open circle: less than - or - greater than ( < , > )

To the right of the number on the number line: greater than

To the left of the number on the number line: less than

373.66 square inches.

The surface area of a cylinder of radius r and height h is given by the equation presented as follows:

The dimensions for the cylinder in this problem are given as follows:

Hence the amount of leather that will be necessary to create the travel case is given as follows:

S = 2 x 3.14 x 8.5 x 6 + 2 x 3.14 x 8.5

S = 373.66 square inches.

Answer:224

Step-by-step explanation:

Okay as you can see, the figure is divided into 3 shapes. 2 rectangles and a right trapezoid.

You can solve the area of the rectangle on the far right by doing 9x6 leaving you with 54.

For the other rectangles you can do 11x12 equaling 132. I got 11 because you know the top is 17 and as you see at the bottom that length you used for the first rectangle is 6, so you do 17-6. You get 12 from adding 9+3.  

For the right trapezoid the formula is A = ( a + b ) x h/2. So you can plug it in and say A=(12+7) x 4/2= 38.

You then add all the areas together (54+132+38= 224) leaving you with the answer of 224.

3. Not a function

4. Not a function

Answer: A

Step-by-step explanation:  578*0.09=52.02~ is 50

No it cannot. There are a couple of ways to prove this. The easiest way is that we know by looking at the angles that we have an Isosceles triangle, because we have 2 angles of the same value. We know that an Isosceles triangle must have at least 2 sides of the same length, which means that this triangle cannot have the side lengths listed.

Answer: the answer is 2

Step-by-step explanation:

Answer: X = 20

Steps:

↳ First, I read the question, “Figure A is a scale image of Figure B”.
(Scale image = a smaller image of the original)

  ↳ Then, I divided 12.5 by 10 which was 1.25

       ↳ After that, I multiplied 1.25 by 16 to get 20.

Answer: length of longest side = 15092 cm

sum of length and breadth = 18856 cm

Step-by-step explanation:

1st question

length : breadth : height

    2     :       3      :      4

2 + 3 + 4 = 9

33957 ÷ 9 = 3773

longest side is the height because it has the biggest number in the ratio

∴ longest side = 4 × 3773 = 15092 cm

2nd question

length : breadth : height

    2     :       3      :      4

2 + 3 + 4 = 9

33957 ÷ 9 = 3773

→ length = 2 × 3773 = 7546 cm

→ breadth = 3 × 3773 = 11319 cm

∴ length + breadth = 7546 + 11319 = 18865 cm

Hope this helps!

The Length of longest edge of the box = 28 cm

The Sum of length and breadth of the box = 35 cm

Steps to calculate the length, breadth and height

Given, ratio(length : breadth : height) = (2:3: 4)

Let length = 2x, breadth = 3x and, height = 4x

Given, the sum of the cubes of length, breadth, and height of the box equals 33957 cm, therefore

[tex](2x)^3[/tex] + [tex](3x)^3[/tex] + [tex](4x)^3[/tex] = 33957

8[tex]x^{3}[/tex] + 27[tex]x^{3}[/tex] + 64[tex]x^{3}[/tex] = 33957

99[tex]x^{3}[/tex] = 33957

[tex]x^{3}[/tex] = 343

[tex]x^3[/tex] = [tex]7^3[/tex]                                                  

x = 7.

Therefore, length    = 2x = 2*7 = 14 cm, breadth = 3x = 3*7 = 21 cm, height   =  4x = 4*7 = 28 cm. Hence, Length of longest side(height) = 28 cm, Sum of length and breadth = 35 cm

Answer:

F : y = -x + 4

Step-by-step explanation:

The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)

Such a line has negative slope

Equation will be of the form

y = mx + b where m is a negative number

We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction

Let's examine options F and G

F:  y = - x + 4
G: -9x + 3

Plug in some values for x from the graph and see which of the lines comes closest to the  y values  computed from the equations

At x = -5, the y value from the graph appears to be either 7 or 8

F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value

G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value

At x = 0; the y value from graph is close to 4

From the equations we get
F: y = -x + 4 ==>  y = -(0) + 4 = 4; pretty darn close

G: y  -9x + 3 => y = -9 + 3 = -6; large difference

One more point
At x = 20, the point on the graph appears to be close to -19

From the equations we get

F: y = -x + 4 = -20 + 4 = -16; not too different

G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off

So the best line of fit would be

F : y = -x + 4

The equation that best represents the line of fit from the scatter plot is given as follows:

y = -x + 4.

The slope-intercept representation of a linear function is given by the equation shown as follows:

y = mx + b

The coefficients m and b have the meaning presented as follows:

From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:

b = 4.

When x = 20, y is approximately -16, hence the slope m is obtained as follows:

-16 = 20m + 4

20m = -20

m = -1.

Hence the function is:

y = -x + 4.

Answer:

111

Step-by-step explanation:

114-3

Answer:

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.

In other words you get the basic idea, you can also just count, but whatever.
