The price of an item is p dollars. The store owner decides to mark this price up by 35%. Which expression correctly describes the new price?

Answer:

CD= 4.25

Step-by-step explanation:

so CD is similar to RS

and the difference between the shapes are 3.75cm.

so 8 - 3.75 =4.25

Answer:

7/100×300 you get 21 lol

Answer:

7% of 300 = 21

Step-by-step explanation:

Here's how it's done:

7 ÷ 100 × 300 = 21

Hope this helps! :)

Answer:

23.225%

Step-by-step explanation:

Runtime in June (x1) = 7:45 = (7 * 60) + 45 = 465

Runtime in September (x2) = 5:57 = (5*60)+57 = 357

Percentage change in Runtime :

[|x2 - x1|÷ x1] * 100%

[|357 - 465| ÷ 357] * 100%

108 / 465 * 100%

0.23225 * 100%

= 23.225%

Answer:

Step-by-step explanation:

Answer:

has no solution.

Step-by-step explanation:

you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.

Answer:

infinite solutions  

Step-by-step explanation:

you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.

-7(y= 1.5x - 6) which equals the equation below

-7y= -10.5x-42 then combine the other equation

7y=10.5x+42 and that equals

0=0

Answer:

basically do 23+35+27+48+18+35= 186 then divide it by how many there are (6) = 31 so the answer is 31

Answer:

31 is the mean points Jeremy scored

Answer:

14 ft³

Step-by-step explanation:

Previous wardrobe : 7 feet tall, 3 feet wide, and 2 feet long

Volume of previous wardrobe = length × width × height

= 7 ft × 3 ft × 2 ft

= 42 ft³

Volume of previous wardrobe = 42 ft³

New wardrobe: 7 feet tall, 4 feet wide, and 2 feet long

Volume of new wardrobe = length × width × height

= 7 ft × 4 ft × 2 ft

= 56 ft³

Volume of new wardrobe = 56 ft³

What is the difference in volume of the two wardrobes?

Difference in volume of new wardrobe and previous wardrobe = Volume of new wardrobe - Volume of previous wardrobe

= 56 ft³ - 42 ft³

= 14 ft³

Difference in volume of new wardrobe and previous wardrobe = 14 ft³

Answer:

D 18

Step-by-step explanation:

Answer:

18x≤54

Answer:

620+0.15x=total payment

Step-by-step explanation:

It is the price of the recipe plus the amount the representative gets per bottle sold. Replace x with the number of bottles sold and multiply it by the 0.15. Add the 620 and you get your total.

Answer:a) 34916  b) 411

Step-by-step explanation:

Answer:

1. The area is found by using the formula for a rectangle

The area is 150 cm²

2. The area is found by the definite integral for the area between two points under a curve

3. The methods are different

The methods are different because the area of figure A is found by the multiplication between the dimensions, while the area of figure B is found by the difference between the values of the integral of the function between the points

Step-by-step explanation:

1. The area of the shaded figure A is found by multiplying the dimensions of the figure, which is the length multiplied by the breadth of the figure

From the question, we have;

The area of the rectangular figure, A = Length × Breadth

The length of the figure = 15 cm

The breadth of the rectangular figure = 10 cm

Therefore, we have;

A = 15 cm × 10 cm = 150 cm²

The area of the rectangular figure, A = 150 cm²

2. The bell shape of the figure B is obtained from a function f(x) as obtained from MIT mathematics website as follows;

[tex]f(x) = e^{-t^2}[/tex]

Therefore the area of the shaded region in the bell shaped figure between the points 0 and 1 on the x-axis is found by integration as follows;

[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt = \dfrac{1}{2} \cdot \sqrt{\pi} \times erf(t)[/tex]

Using a graphing calculator, we have;

[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt \approx 0.746824[/tex]

3. The method of finding the area of figure A is different from the method of finding the area of the figure B

The methods are different because the area of figure A is the area of the whole figure of a geometric shape with known formula for area while the area of of the shaded region has no predefined formula but is calculated using the calculus for the area under a curve.

Answer:

A) 32.5 *but there's a typo... it's supposed to be 23.5)

Step-by-step explanation:

The area of the whole triangle is 31.5 sq. in. Then, subtracting the area of the cutout (8 sq. in.) from the triangle (31.5 sq. in.) will give you a final answer of 23.5 sq. in. I think the teacher messed up and did 32.5 instead of 23.5

Answer:

Solution: 36x2−9

Step-by-step explanation:

So, you always have to start with distrubuting which is basically dividing.

Heres the equation that I started with. You can do it differently of course.

36x2+18x-3(6x+3)

combine like terms.

36x2-9

, your solution will be

36x2-9

Answer:

See explanation below

Step-by-step explanation:

Volume = (11)(10)(7) = 770 cubic centimeters

Surface area = (2)(10)(7) + (2)(11)(7) + (2)(11)(10) = 1774 square centimeters

b) Surface area (How much wax can cover the cube)

c) Volume (How much juice will be inside the cube)

Step-by-step explanation:

In this arithmetic sequence, the common difference d is 7. You can find this by subtracting a term from the consecutive term: 16 - 9 = 7, 23 - 16 = 7. In order to find the next four terms, keep adding 7 to the previous term. The next four terms are 30, 37, 44, and 51.

Answer:

Step-by-step explanation:

[tex]a_{1}[/tex] = [tex]\frac{3}{4}[/tex]

d = - [tex]\frac{1}{4}[/tex]

[tex]a_{2}[/tex] = [tex]\frac{3}{4}[/tex] + ( - [tex]\frac{1}{4}[/tex] ) = [tex]\frac{1}{2}[/tex]

[tex]a_{3}[/tex] = [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex] = - [tex]\frac{1}{2}[/tex]

[tex]a_{4}[/tex] = - [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex] = - [tex]\frac{3}{4}[/tex]

[tex]a_{5}[/tex] = - [tex]\frac{3}{4}[/tex] - [tex]\frac{1}{4}[/tex] = - 1

Answer:

A situation in which you would need to calculate the surface area or volume of a solid would be when you are going to put up wallpaper in a room. You need to measure the room and the wallpaper. If you wanted to put up moldings on the walls too, than you would need to measure the surface area and volume of the moldings as well so you would know where to cut the wood to fit witht eh wall shape of the room.
