Answer:

positive 42

Step-by-step explanation:

because to negatives make a positive and then you would multiply the two by eachother because they are directly beside eachother and then you do 7*6 which equals to 42 I really hoped this helped you

Answer:

5 inches

Step-by-step explanation:

Given that :

There are two pieces of ribbon with length:

15 inches and 20 inches

To cut ribbon into equal sizes with no ribbons left ; the greatest length in inches of the ribbon would be :

Calculate the greatest common factor of both lengths : 15 inches and 20 inches

____15___20

_5__ 3___4

OR

Find the factors of 15 and 20 and pick the greatest common to both

15 : 1, 3, 5, 15

20 : 1, 2, 4, 5, 10, 20

Greatest factor common to both = 5

Hence the greatest length she can cut the ribbons into without any leftover is 5 inches

Answer:

-13/9 = x

Step-by-step explanation:

8/9 = x + 1/3(7)

~Simplify right side

8/9 = x + 7/3

~Subtract 7/3 to both sides

-13/9 = x

Best of Luck!

x= -13/9

1/3(7) = 1/3 x 7

1/3(7) = 7/3 = 2 1/3

PART A: 2.25

Answer: Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of coterminal angles that can be found?

Step-by-step explanation:

Answer:

$2.14285714286 or $2.14

Step-by-step explanation:

This is quite simple.

#1. Take-away $15 from $30 because "$15 remain"ed.

#2. Then you get $15 dollars and divide that by 7, because she used the "same amount to download" each song so you divide 15 among 7 equally.

#3. There you go! You have the answer! it's: $2.14285714286 or $2.14 if simplified.

WooHoo!

Answer:

2x + 200 = 6x + 120

Step-by-step explanation:

Super-Clean house cleaning company:  2x + 200

Power Bright: 6x + 120

Now, they have to be equal because we are trying to find the equation for total charges.

So, your equation would be 2x + 200 = 6x + 120.

Hope this helps!

Answer:

Step-by-step explanation:

Let the number of linear feet = x

Let the total cost = y

Condition One

y = 200 + 2x

Condition Two

y = 120 + 6x

Now you want the ys to be the same.

200 + 2x = 120 + 6x

Answer:

I'm late but the answer is 416 cm

Step-by-step explanation:

If every cm of the model car equals 32 centimeters of the actual car, you would just multiply 13 by 32 and get 416

Answer:

4

Step-by-step explanation:

Hi so basically you just convert the inches to decimals so

0.5 x 0.5 x 0.25 = 0.0625

Use a calculator to convert 0.0625 into fraction which is [tex]\frac{1}{16}[/tex]

Multiply [tex]\frac{1}{4}[/tex] by 3 = [tex]\frac{1}{64}[/tex]

Then multiply [tex]\frac{1}{16}[/tex] by [tex]\frac{1}{64}[/tex] = 4

Soo that was probably very confusing, but I hope it helps! :)

Plz click the Thanks button, I rrly appreciate it!

Answer:

Step-by-step explanation:

We assume in this context that a "1/4 unit cube" is a cube that is 1/4 unit on a side. When the "unit" is "inches", then the "1/4 unit cube" is a cube that is 1/4 inch on a side.

It should not take too much thought to realize that a dimension that is 1/2 = 2/4 inches will be 2 cubes long. A dimension that is 1/4 inch will be 1 cube long.

Then the 1/2 by 1/2 by 1/4 prism will have dimensions in "cubes" of ...

  2 cubes × 2 cubes × 1 cube

As with any rectangular prism volume calculation, the volume is the product of the dimensions:

  V = LWH = (2)(1)(2) = 4 . . . cubes

_____

For this prism, it should not be too difficult to see that if you stack 2 smaller cubes on top of two smaller cubes, the overall dimensions of that will be 1/2 inch wide by 1/2 inch high by 1/4 inch deep.

_____

Additional comment

Which dimensions you call length, width, and height are irrelevant, as each is interchangeable with any other in the formula for volume. Here, I have elected to call height the vertical dimension, length the left-right horizontal dimension, and width the front-back dimension. You are welcome to choose an assignment of names to dimensions that suits your taste (or that of your grader).

Answer:

$163

Step-by-step explanation:

Bob worked 26 hours and earn $7 per hour. Multiply 26 with 7:

26 x 7 = 182

Bob made a total of $182 last month.

Bob then spent $19. Subtract 19 from the total earned:

182 - 19 = 163

Bob has $163 left.

~

Answer:

He has $163 dollars left

Step-by-step explanation:

Because first we needed to find out how much did he make in 26 hours, 29 (hours) x $7 (per hour) = $182

Then he spent $19, $182 (how much he made in 26 hours) - $19 (how much he spent) = $163

Answer:

rate of interest is 6 percent per annum.

Step-by-step explanation:

Formula for simple interest is given

SI = p*r*t/100

where

SI is simple interest

p is principal

r is the rate of interest

t is the time

_______________________________

Given

p = 6400

SI = 768

t = 2 years

r we have to find

lest sue the above formula and plug the given value in it

768 = 6400*r*2/100

=> 768 = 128r

=> r = 768/128 = 6

Thus, r = 6%

thus, rate of interest is 6 percent per annum.

Answer:

b(x) = -2X² + 19X + 114

Step-by-step explanation:

b(x) = total revenue generated per day

total revenue formula ⇒ b(x) = price x quantity

price = $3 current price + 0.5X price increase = 3 + 0.5X

quantity = 38 current quantity sold - 4 books per X = 38 - 4X

b(x) = (3 + 0.5X) · (38 - 4X)

b(x) = 114 -12X + 19X - 2X²

b(x) = -2X² + 19X + 114

Answer:

-3x – 4y = -4

Step-by-step explanation:

Answer:

- 12

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence.

9 - 16 = 2 - 9 = - 5 - 2 = - 7

Thus to find the next term subtract 7 from the previous term, that is

- 5 - 7 = - 12
