Part 1: How many phone numbers can be made if all the digits (that is, 10 digits) need
to be filled in and any single digit number (0-9) can be used for any digit?

Part 2: How many phone numbers can be made if the first digit must be 1, the second digit must be a number in the range 3-5, the third digit must be a number in the range
(6-9), and the last seven digits can be any single digit number 0-9?


PLZ HELP ASAP WOULD GREATLY APPRECIATE IF U R HERE TO NOT HELP DON'T BOTHER OR DON'T PUT A LINK THAT LEADS TO NOTHING THANK YOU!

Answer:

Step-by-step explanation:

2^3 . 2^- 5 . 2^- 1

= 2^( 3 - 5 - 1 )

= 2^( 3 - 6 )

= 2^- 3

= 1 / 2^3

= 1 / 8

If

2 . 2^3 . 2^- 5 . 2^- 1

= 2^1 . 2^3 . 2^- 5 . 2^- 1

= 2^( 3 - 5 - 1 + 1 )

= 2^( 3 - 5 )

= 2^- 2

= 1 / 2^2

= 1 / 4

Answer: 3750 m

Step-by-step explanation:

Remember that there are different units; one is in km and the other is in m

I’ll go from km to m

1 km = 1000 m

Therefore 5 km = 5 x 1000 m

5km = 5000 m

Now, we just subtract to find how much more Suzanne have to run

5000 m - 1250 m = 3750 m

Answer:

-2

Step-by-step explanation:

To find the slope of a line with 2 given points, you use the formula

m=y2-y1/x2-x1

Now you plug in the points which would be m=3-(-1)/2-4 which equals m=4/-2

4/-2 equals -2

The slope is -2

Answer:

there are twelve total combinations

Step-by-step explanation:

just by looking at the problem though,

ABCD

AB

AC

AD

BA

BC

BD

CA

CB

CD

DA

DB

DC

normally, because some of them are repeated, we need to get rid of some

AB

AC

AD

BC

BD

DC

since this is about passwords though, we need to keep all of the same twelve combinations because the order of the letters are important

Answer:

-2x+5

Step-by-step explanation:

Let's simplify step-by-step.

−4x+5+5x−3x

=−4x+5+5x+−3x

Combine Like Terms:

=−4x+5+5x+−3x

=(−4x+5x+−3x)+(5)

=−2x+5

Hope this helps :)

Answer:

Part A: One.

Part B: (3, 5)

Step-by-step explanation:

Part A: A solution to a pair of equations is generally where the two functions intersect. As we can see, a graph is provided, so things are facilitated. We can see that they only intersect once, which means only one answer.

Part B: The solution, which as we have learned is where the two lines intersect, is (3, 5), as that is, again, the point of intersection.

Answer:

(2m^2-3)(m-1)

Step-by-step explanation:

2m^3-2m^2+3-3m

2m^3-2m^2-3m+3

2m^2(m-1)-3(m-1)

(2m^2-3)(m-1)

Answer:

(2m^2-3)(m-1)

Step-by-step explanation:

2m^3-2m^2+3-3m

=(2m^3-2m^2)+(3-3m)

=2m^2(m-1)+3(1-m)

=(m-1)(2m^2-3)

=(2m^2-3)(m-1)

Answer:

12-5=7

area of rectangle=length x width

7x20=140

area of square = side^2

5x5=25

140+25=165

hope that answers your question

Step-by-step explanation:

Answer:

165 in^2

Step-by-step explanation:

Split the polygon and make 1 rectangle and 1 square.

Now you got a 5x5 square and a 7x20 rectangle

Do the square one first...

5 x 5=25 in

Now do the rectangle one...

7 x 20=140 in

Last add them...

25+140=165 in^2

Hope this helps!!

Have a good day!!!

Answer:

201.1

Step-by-step explanation:

πx8²=201.1

Answer:

3. True

4. False

5. A

Step-by-step explanation:

Answer:

x = 3.

Step-by-step explanation:

(∛44x - 7) - 5 = 0

Cube the expression.

44x - 7 - 125 = 0

Subtract.

44x - 132 = 0

Add 132 to both sides.

44x = 132

Divide by 44.

x = 3.

Proof:

(∛44x - 7) - 5 = 0

(∛44(3) - 7) - 5 = 0

(∛132 - 7) - 5 = 0

(∛125) - 5 = 0

5 - 5 = 0

0 = 0

Answer:

-1/8

Step-by-step explanation:

calculate the product

-1/8

Answer:

negative 1/8 or 0.125

Step-by-step

-1/2 cancells out the plus, so it is just 3/8 - 4/8 = -1/8

Answer:

7(left answer), 3(top left answer), and 10(top right answer)

Step-by-step explanation:

So what are two things that go into 21?

Out of those two, which is a factor of 70? Right off the bat we know 7 is.

THis isnt the greatest factor of 70, but it is for both 21 and 7, so now we know the left answer for hieght is 7.

Now 3 must be the top left answer, because you must make 21 with 7. 7 Goes into 21 3 times, so it has to be 3. So now we know that the top left anhswer is 3.

Finally we have our top right answer. We already know that the height is 7, now we need to find the width. All we have to do is divide 70 by the 7 heigh, and we will find our width:

70/7

=

10

So now we know that the top right answer is 10.

Sorry that you couldnt get a real answer from people, I hope this is in time to help!

45 because it is what I think
