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:

The time it took until 2 inches of rain fell is 8 hours

Step-by-step explanation:

You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x

To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:

2= 0.25*x

Solving:

[tex]\frac{2}{0.25}=x[/tex]

8 = x

So, remembering that the amount of time it had been raining, x, is expressed in hours, the time it took until 2 inches of rain fell is 8 hours.

Answer:

Step-by-step explanation:

The formula u have written is incorrect. It should be C = [5 (F-32)]÷9.

To identify which is hotter, you need to bring both the values either in celsius or in Fahrenheit.

Let's convert 85°F to celsius:

C = [5 ( F - 32 )] ÷ 9

C = [5 ( 85-32 )] ÷ 9

C = [5 (53)] ÷ 9

C = 29.4 °C

thus 30°C is hotter than 85°F

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.

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.

-18x×3>x

Calculate the product

-54x>x

now we do the same thing only different way ok

-18x×3

Multiply a negative and a positive equals a negative:(-)x(+)=(-)

-(18×3)x

Multiply the numbers

-54x

now we do the same thing only different way ok

-54x>x

Move variable to the left hand side and change its sign

-54x-x>0

the same way only different way ok

-54x>x

Move variable to the left by adding its opposite to both sides

-54x-x>x-x

the sum of two opposites equals 0

-54x-x>0

Collect like terms

-55x>0

the same way only different way ok

-54x-x

If a negative term doesn't have a coefficient, it is considered that the coefficient is -1

-54x-1x

Collect like terms by calculating the sum or difference of their coefficients

(-54-1)x

Calculate the difference

-55x

now we do the same thing only different way ok

-54x-y>0

Collect like terms

-55x>0

Divide both sides of the inequality by -55 and flip the inequality sign

x<0

Now we do the same thing only different way ok

-55x>0

Divide both sides of the inequality by-55 and flip the inequality sign

-55x÷(-55)<0÷(-55)

any expression Divided by itself equals 1

x<0÷(-55)

0 Divided by any non-zero expression equals 0

Answer : x<0

Answer:

Exponents are when you are multiplying numbers by themselves. The symbol is this sign right here ^

Step-by-step explanation:

Exponents are usually shown as ^

but they may also look more like a number that is on the top right corner of a value.

When you have an exponent, since you are multiplying by itself, you get the number times the number times the number on and on, counting on what the value of the exponent is.

If the number looks like this for example 2^5

You should either see that or a 2 with a 5 hugging the top right corner of the 2.

To solve them, you should do 2 x 2 x 2 x 2 x 2, since you are multiplying the 2 by itself 5 times.

2^1 is basically just 2, as you are multiplying 2 by itself no times at all.

2^2 should be 4, because you are multiplying 2 by 2 twice.

2^3 is 2 x 2 x 2 which is 4x2 which is 8.

When a number goes to the power of 0, such as 2^0 it is ALWAYS 1. For some weird reason, exponents going to the power of 0 is always 1, no matter what value the bottom number is.

1^0 = 1

2^0 =1

19442380528^0 = 1

Exponents to the negative power, are more difficult, however is just as easy as remembering the powers of 0.

You just flip the number upside down, so if the number is 3^-2 then it becomes 1/3 ^2

If the number is 3^-4

You get 1/3 x 1/3 x 1/3 x 1/3 which you end up getting 1/81.

You have to square the top numbers too when you are using exponents, so if 2/3 to the power of 3 is used,

you have to do 2/3 times 2/3 times 2/3, which is 2x2x2 over 3x3x3 giving you 8/27.

The same principle applies to when you do negative exponents, which you are just flipping over the fraction or number and doing the exponent.

2/3 to the power of -3, would give you 3/2 times 3/2 times 3/2, which gives you 27/8.

I will not get into much more detail, as it is a big unit to go through, but once you get the hang of them, it is easy to understand. I appologize if you feel lost, but there are many websites that go into more detail much better than me. Khan Academy gives VERY in depth videos on how exponents work with some humor, but I hope this helped at least!

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:

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:

=13x-5

Step-by-step explanation:

Answer:

13x-5

Step-by-step explanation:

You would use distributive property to get 15x-9 and then the -2x+4.

Distributive property works for the numbers in the parenthesis and you multiply the 5x and the -3 by 3.

Then, you would do your basic math to get 13x-5

Answer:c<1

Step-by-step explanation:

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:

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! :)

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).

PART A: 2.25

PART B: 14

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

Answer:2

Step-by-step explanation:

I have the problem on my my review and it says 2

Substituting the given values of X into the function, the value of f(3) - f(4) is 2

Given the function :

f(3) = - 2(3) + 3

f(3) = - 6 + 3 = - 3

For X = 4 :

f(4) = - 2(4) + 3

f(4) = - 8 + 3 = - 5

f(3) - f(4) = - 3 - (-5)

f(3) - f(4) = - 3 + 5 = 2

Therefore, the value of f(3) - f(4) is 2
