15% is written as 0.15 in decimal format.

Multiply the cost of the meal by 0.15.

19.50 x 0.15 = 2.925, which would round to $2.93

The tip is $2.93

To calculate a 15% tip for a $19.50 meal, convert 15% to decimal form (0.15), multiply by the cost of the meal ($19.50), and round to the nearest cent, resulting in a $2.93 tip.

Chris wishes to tip 15 percent to the waiter for his meal which costs $19.50. To calculate the amount of the tip, we need to convert the percentage to a decimal and then multiply it by the cost of the meal. Here's how you can do it:

Convert the tip percentage to a decimal: 15% ightarrow 0.15.

Multiply the decimal by the total cost of the meal: $19.50 imes 0.15.

The calculation gives us the tip amount: $2.925.

Since it's difficult to leave a fraction of a cent as a tip, we would round this to the nearest cent, giving us $2.93.

Therefore, Chris should tip $2.93 to the waiter.

The equation of the line that passes through the point (–1, 1) and has a slope of –2 is y = -2x - 1.

The question is asking for the equation of the line that passes through the point (–1, 1) and has a slope of –2. The formula for a line is y = mx + b, where m is the slope and b is the y-intercept. Since we know the slope (m) is -2, and we have the coordinates of a point on the line (-1,1), we can substitute these values into the formula to solve for 'b', the y-intercept.

So, 1 = -2*(-1) + b, which simplifies to 1 = 2 + b. Solving this for b gives us a y-intercept (b) of -1.

Therefore, the equation of the line that contains the given point and has the given slope is y = -2x - 1.

The total interest accrued on two credit cards in the first month is $28.44, with $19.51 coming from the first card with a balance of $3,745 at 6.25% APR and $8.93 from the second card with a balance of $1,045 at 10.25% APR based on a credit score of 500.

The question involves calculating the total interest accrued on two credit cards in the first month. The first credit card has a balance of $3,745.00 at an annual percentage rate (APR) of 6.25%, and the second credit card has a balance of $1,045.00 with an APR that depends on the credit score. Given a credit score of 500, the APR for the second card is 10.25% (per the provided table).

First, to find the monthly interest for each card, we can use the formula: Monthly Interest = (Balance) x (APR) / 12 months.

For the first card: Monthly Interest for $3,745.00 at 6.25% APR is ($3,745.00) x (0.0625) / 12 = $19.51.

For the second card: Monthly Interest for $1,045.00 at 10.25% APR is ($1,045.00) x (0.1025) / 12 = $8.93.

To find the total interest accrued from both credit cards in the first month, simply add the monthly interest amounts from each card: $19.51 + $8.93 = $28.44.

First day temperature is 0 degree.

Second day temperature is 3 degree higher than first day's temperature.

In order to find the higher temperature we need to add increased temperature in previous day's temperature.

First day given temperature is 0 degree .

Three degree higher than 0 would be 0+3.

On adding 0 and 3 we would get 3.

There are multiple ways that you could graph this quadratic equation. I would start by finding the vertex. The x-value in the vertex is found with -b/2a. The take you value and input back into the equation to find the y-value of your vertex. Then, you could make a list of points on both sides of the vertex to create a table with which to create the parabola.

One

Slope

The general slope intercept equation for a line is

y = mx + b

If you are told outright what the slope is then you can write m = slope in this case - 3

So you have so far is y = -3x + b. Now you use the point to get the y intercept.

(2,5) means that when x = 2, y = 5. that allows you to solve for b

Y intercept

When x = 2, y = 5. Substitute that into the general equation with the slope.

5 = -3x + b            Put 2 in for x

5 = -3 * 2 + b         Multiply -3 * 2

5 = - 6 + b             Add 6 to both sides

5 + 6 = b

11 = b

Answer

y = -3x + 11

Two

This question is a little harder. You have to find the slope.

Slope Formula

[tex]\text{m = } \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

Givens

Points (2, -1), (-6, - 5)

y2 = -1 ; y1 = -5; x2 = 2;  x1 = -6

Solve

m = (-1 - - 5)/(2 - - 6) = (-1 + 5)(2 + 6) = 4/8 = 1/2

Now find the y intercept. Use either one of the given points

(2,-1) when x = 2, y = - 1

y = 1/2 x + b      Show what you have so far. Put in x = 2 for x and y = - 1 for y

-1 = 1/2(2) + b    Multiply 2*1/2

-1 = 1 + b            Subtract 1 from both sides.

-1 -1 = b

- 2 = b

Answer: A.) 7

Step-by-step explanation: a p e x

That would be point-slope form, standard form, and slope-intercept form.

The three forms of linear equations are the standard form (Ax + By = C), the slope-intercept form (y = mx + b), and the point-slope form (y - y1 = m(x - x1)).

The three forms of linear equations are:

The standard form, which appears as Ax + By = C, where A, B, and C are constants, and A and B are not both zero.

The slope-intercept form, given by y = mx + b, with m representing the slope and b representing the y-intercept.

The point-slope form, which is written as y - y1 = m(x - x1), where m is the slope and (x1, y1) is a known point on the line.

Each form is useful in different contexts: the standard form is often used when both x and y intercepts are integers; the slope-intercept form is useful for quickly identifying the slope and intercept; and the point-slope form is handy when a point on the line and the slope are known.

Step-by-step explanation:

If Jill pays with a credit card, her payment will be recorded immediately. This means that the item could be shipped almost as soon as she pays for it. On the other hand, if she uses a check or money order, then her payment will take a while to be received, as she would have to send the physical item over the mail. Therefore, she would receive her package earlier if she paid with a credit card.

The next number is 1440.

Here is the pattern:

12*2=24

Answer:

11 cupcakes

Step-by-step explanation:

Given that 114 dozen cupcakes can be prepared from 123 cups of flour.

i.e. if flour is 123 cups no of cupcakes that can be made = 114x 12 = 1368

For 1 cup how many cupcakes?

i.e. when cup reduces no of cupcakes also will decrease.

This relation is directly proportional.

Hence answer = 1x1368/123 =11.1219

Approximately 11 cupcakes Rashida can prepare

The question is about proportion. The recipe states that 1368 cupcakes require 123 cups of flour. Therefore, with 1 cup of flour, Rashida can make approximately 11 cupcakes.

The question is asking for the number of cupcakes that can be made with one cup of flour. This is a problem of ratios or proportions, a common subject in Mathematics. The recipe states that 114 dozen cupcakes (which is 1368 cupcakes) need 123 cups of flour, hence the ratio is 1368 cupcakes to 123 cups of flour.

To find out how many cupcakes we can make with 1 cup of flour, we set up a proportion: 1368/123 = x/1. Here, 'x' represents the number of cupcakes we can make with 1 cup of flour. Solving for 'x' gives us the number of cupcakes we can make. By doing this, we get 'x' = 11.12, but since we can't have a fraction of a cupcake, Rashida can make approximately 11 cupcakes with 1 cup of flour.

Elizabeth had to save $280 each month.

The correct option is (2).

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.

As per the given data:

The annual tuition at a public two-year college last year was $3,200.

Expected growth in the tuition fee = 5%

We have to find the amount Elizabeth should have saved monthly during the previous year to pay her tuition fees.

For finding the increase in tuition fee:

= 5% of 3200

= (5/100) × 3200

= $160

Tuition fees after growth = 3200 + 160 = $3360

Amount Elizabeth had to save each month = Tuition fees after growth/12

= 3360/12

= $280

Elizabeth had to save $280 each month.

Hence, Elizabeth had to save $280 each month.

The expression for the cost of the ABC Book Club is 2x + 40.  The expression for the cost of the Easy Book Club is 3x + 35.  To find when the total charge for both book clubs is equal, the two expressions must equal each other. (x = the number of books read)

2x + 40 = 3x + 35

Subtract 35 from both sides.

2x + 5 = 3x

Subtract 2x from both sides.

5 = x

So, the total charge for each club is equal when 5 books are read.

The number of books read from both ABC and Easy book clubs must be 5 in other to have a equal monthly charge.

Let the number of books read = b

ABC Book club :

Monthly charge = $40

Fee per book read = $2

Total monthly charge = 40 + 2b - - - - (1)

Easy Book Club :

Monthly charge = $35

Fee per book read = $3

Total monthly charge = 35 + 3b - - - (2)

To obtain an equal monthly charge ;

Equation(1) = Equation(2) and solve for b

40 + 2b = 35 + 3b

40 - 35 = 3b - 2b

5 = b

Hence, to have an equal monthly charge, the number of books read from each club must be 5.
