What is the PERCENT DECREASE: 1) PRINCETON: December - 50 January - 40 2) WORCESTER: December - 256 January - 197 3) CHICAGO: December - 7050 January - 6708

Answers

Answer: See explanation

Step-by-step explanation:

PRINCETON:

December - 50

January - 40

Decrease = 50 - 40 = 10

Percentage Decrease = Decrease/Original value × 100

= 10/50 × 100

= 20%

2) WORCESTER:

December - 256

January - 197

Decrease = 256 - 197 = 59

Percentage Decrease = Decrease/Original value × 100

= 59/256 × 100

= 23.05%

3) CHICAGO:

December - 7050

January - 6708

Decrease = 7050 - 6708 = 342

Percentage Decrease = Decrease/Original value × 100

= 342/7050 × 100

= 4.85%

Step-by-step explanation:

π = 3.14(aka pi)

d=diameter

h=height

^=exponent

The formula for doing this types of problem is 2π d/2h + 2π(d/2)^2. So all you do is fill in the diameter and height of the variable.

2π 7/2(10.4) + 2π(7/2)^2=305.68

What is the image of the point (9, – 7) after a rotation of 270° counterclockwise
about the origin?

Answers

Answer:

The image if the point is (-7, -9)

Step-by-step explanation:

If The point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)

∵ The given point is (9, -7)

x = 9 and y = -7

∵ The given point is rotated 270° counterclockwise about the origin

→ By using the third rule above

∴ The image of the point is (y, -x)

→ That mean change the sign of x-coordinate, then switch them

∵ x = 9 and y = -7

The image if the point is (-7, -9)

Answer:

B) 37.5 cm squared!

Step-by-step explanation:

First, we know that a triangular prism has 5 faces, so in order to find the surface area of this prism, we must find the area of each face, and then add them together.

Face 1 (Rectangle): 6.5 * 1.5 = 9.75

Face 2 (Rectangle): 6 * 1.5 = 9

Face 3 (Rectangle): 2.5 * 1.5 = 3.75

Face 4 (Triangle): (6 * 2.5)/2 = 6

Face 5 (Triangle): (6 * 2.5)/2 = 6

Now, we add all the areas of the faces together.

9.75 + 9 + 3.75 + 6 + 6 = 37.5

37.5 is the surface area of the whole triangular prism.

The product of two consecutive integers is 72. Write a quadratic equation to find the integers, and then solve it.

Answers

Answer:

9 x 8

Step-by-step explanation:

Answer:

ok so basically what you do is since you know they are consecutive numbers, one is x and the other is x+1. Now when you multiply x and x+1 you get 72 , so this basically turns into a quadratic where x(x+1)=72. Thus,X^2+x=72. subtract 72 from both sides- x^2+x-72=0. Then you can solve for x using the quadratic formula or some other way and you get x to be 8 or -9. OH WAIT THERE IS ANOTHER SOLUTION IT IS -9 AND -8. . Anyway yea hoped this helped.

The bakers fits 26 rolls on to a pan that measures 1 5/8ft2. How many square feet does the baker use for each roll

Answers

Answer: 1/16 ft²

Step-by-step explanation:

The baker put 26 rolls into a pan that has an area of 1⁵/₈ ft².

Each roll is therefore taking up a space of:

= Area/ Number of rolls

Convert the fraction to an improper fraction:

1 ⁵/₈ = 13/8

= 13/8 ÷ 26

= 13/8 * 1/26

= 13/208

= 1/16 ft²

David works in a department store selling clothing. He makes a guaranteed salary of $250 per week, but is paid a commision on top of his base salary equal to 5% of his total sales for the week. How much would David make in a week in which he made $1500 in sales? How much would David make in a week if he made xx dollars in sales?

Answers

Answer:

250 + 0.05 (1500)

250 + 75 = $325 david made i a week with 1500 in sales

250 + 0.05(xx) is how much david would make if he sold xx that week

Step-by-step explanation:

i hope this helped :)

A linear function is a function that changes at a constant rate.

David would make $325 if he made $1500 in sales,He would make 250 + 0.05x if he made $x in sales

The given parameters are:

Flat Salary = $250 weeklyCommission= 5%

A linear function is represented as:

[tex]C(x) = b + mx[/tex]

Where:

b represents the y-interceptm represents the slope

So, we have:

[tex]C(x) = 250 + 5\% \times x[/tex]

Express 5% as decimal

[tex]C(x) = 250 + 0.05 \times x[/tex]

[tex]C(x) = 250 + 0.05x[/tex]

On a sale of $1500, the equation becomes

[tex]C(x) = 250 + 0.05 \times 1500[/tex]

[tex]C(x) = 325[/tex]

Hence. David would make $325 if he made $1500 in sales, and he would make 250 + 0.05x if he made $x in sales
