Shayla bought 24 cupcakes. Each cupcake cost $0.35, including tax. Of the cupcakes she bought, 2 3 2 3 were vanilla, 1 12 1 12 were chocolate, and the rest were strawberry. What was the total cost of only the vanilla cupcakes?

Answers

Answer:

[tex]Vanillas = \$5.6[/tex]

Step-by-step explanation:

Given

[tex]Cup\ Cakes = 24[/tex]

[tex]Cost = \$0.35[/tex] (each)

[tex]Vanilla = \frac{2}{3}[/tex]

[tex]Chocolate = \frac{1}{2}[/tex]

Required

Determine the cost of all vanilla cupcakes

First, we need to determine the number of vanilla cakes.

This is calculated by multiplying the fraction of Vanilla by number of cupcakes

So:

[tex]Vanilla = \frac{2}{3} * 24[/tex]

[tex]Vanilla = \frac{2 * 24}{3}[/tex]

[tex]Vanilla = \frac{48}{3}[/tex]

[tex]Vanilla = 16[/tex]

Since 1 cupcake costs $0.35.

16 would cost 16 * $0.35

So:

Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]

Kedar earns a monthly salary of $2,200 plus a 3.75% commision on the amount of his sales at men's clothing store. What would he earn this month if he sold $4,500 in clothing?

Answers

Answer:

$2368.75

Step-by-step explanation:

Kedar earns a monthly salary of $2200 and a commission of 3.75%

He sold $4500 this month

The first step is to calculate his commission for this month

His commission can be calculated as follows

= 4500 × 3.75/100

= 4500 × 0.0375

= 168.75

Therefore yr amount earned this month can be calculated as follows

= 2200 + 168.75

= $2368.75

Tiffany buys a basket of watermelons on sale for \$9$9dollar sign, 9 before tax. The sales tax is 9\%9%9, percent.
What is the total price Tiffany pays for the basket of watermelons?
\$\$ dollar sign, space

Answers

Answer:

Tiffany pays a total price of $9.81 for the basket of watermelons

Step-by-step explanation:

Percentages

To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.

If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:

$9 * 9 / 100 = $0.81

Now we add it to $9 to get the total price paid by Tiffany:

Total price = $9 + $0.81 = $9.81

Tiffany pays a total price of $9.81 for the basket of watermelons

Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R. From P to Q from P to R from Q to S from Q to R from S to P from R to P from P to S

Answers

I attached a diagram that will aid the understanding of the question.

Firstly, I would love to review what a scale factor is before going into the question.

If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.

Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:

1. From P to Q, the scale factor greater than one because Q is bigger than P.

2. From P to R, the scale factor is greater than one for the same reason.

3. From Q to S, the scale factor is less than one because S is smaller than Q.

4. From Q to R, the scale factor is greater than one because R is bigger than Q.

5. From S to P, the scale factor is equal to one because they are equal.

6. From R to P, the scale factor is less than one because p is smaller than R.

7. From P to S, the scale factor is equal to one because they are equal.

What is the point-slope form with the slope -6 and the line through (1,-4)?

Answers

Answer:

y-(-4)=-6(x-1)

its is either (x-1), or (x+1). Im not sure on the last part

Step-by-step explanation:

hope this helps :3

if it did pls mark brainliest

plug those numbers into y - y1 = a(x - x1)

so you would get y-(-4) = -6(x - 1) (this is your point-slope form)

simplify to get y + 4 = -6x + 6

simplify more to get y = -6x + 2

then 6x + y =2 (this is your standard form)

A person jogs 4 kilometers in 32 minutes, the 2 kilometers in 22 minutes, and finally 1 kilometer in 16 minutes. What is the jogger's average speed in kilometers per minute?

Answers

Answer:

0.1km per min

Step-by-step explanation:

what is average speed:

"The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time."

step one:

given data

Distances   Time

4km             32min

2km              22min

 1km              16min

the total distance covered is

4+2+1= 7km

the total time taken = 32+22+16=70min

the average speed= distance/time

average speed= 7/70= 0.1km per min

What rule would you allow to test weather (x,y) is on line l

Answers

Answer:

Step-by-step explanation:

If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.

Slope of a line passing through two points C(4, 5) and D(8, 10),

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

m = [tex]\frac{10-5}{8-4}[/tex]

m = [tex]\frac{5}{4}[/tex]

Equation of the line passing through C(4, 5) and slope m = [tex]\frac{5}{4}[/tex]

y - y' = m(x - x')

y - 5 = [tex]\frac{5}{4}(x-4)[/tex]

y = [tex]\frac{5}{4}x-5+5[/tex]

y = [tex]\frac{5}{4}x[/tex]

If point B(4, 0) lies on the line CD,

0 = [tex]\frac{5}{4}(4)[/tex]

0 = 5

Which is not true.

Therefore, point B doesn't lie on line CD.

Manuel and Felicia are comparing how much
money they have
• Manuel has $250.
• He saves $150 per week,
• Felicia has $1,650.
• She spends $200 per week.
• Let x = the number of weeks
• Let y = the amount of money at the end
of the week.
Which system of equations represents this
situation?

Answers

Answer:

y = 250 + 150xy = 1650 - 200x

Step-by-step explanation:

Equation for Manuel:

y = 250 + 150x

Equation for Felicia:

y = 1650 - 200x

Solving we get:

250 + 150x = 1650 - 200x150x + 200x = 1650 - 250350x = 1400x = 1400/350x = 4 weeks

and

y = 250 + 150*4 = 250 + 600 = $850

After 4 weeks Manuel and Felicia will have equal amount of money- $850
