m = 92

n = 68

p = 92

Step-by-step explanation:

x = 20

2 + 3x = 62

-2           -2

----------------

   3x = 60

  -----   -----

    3       2

    x = 20

m = 92

20 + 68 = 88

180 - 88 = 92

n = 68

The vertical angle is 68 degrees

p = 92

Vertical angle is m, which is 92.

Alexandra's family took a road trip to the Grand Canyon. Alexandra slept for the last 48 miles of the trip. If the total length of the trip was 800 miles, what percentage of the total trip had they travelled when Alexandra fell asleep

Answers

Answer:

She fell asleep for 6% of the trip.

Step-by-step explanation:

You take 48 and divide it by 800. That gives you 0.06.

0.06 equals 6%.

Answer:

6%

Step-by-step explanation:

Divide 48 and 800 together.

48/800 = 0.06

48 is the miles she's sleeping and 800 is the total miles.

So, she was asleep only 6% of the trip.

If 5x + 3 = 23 , what does 12x - 10 equal ?

Answers

Answer:

38

Step-by-step explanation:

5x+3 = 23

5x = 23-3

x = 20/5

x = 4

12x-10 = ?

12 (4) -10

48 -10

38

The value of the expression 12x - 10 will be 38.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that 5x + 3 = 23. To calculate the value of 12x -10 first calculate the value of x.

5x+3 = 23

5x = 23-3

x = 20/5

x = 4

Calculate the value of 12x - 10.

12x-10 = ?

12x-10 = 12 (4) -10

12x-10 = 48 -10

12x-10 = 38

Therefore, the value of the expression 12x - 10 will be 38.

Answers

Answer:

a) C = 1.40 + .4M

b) $4.60

c) 46.5 <= M (miles)

Step-by-step explanation:

a) Cost = initial fee + 0.40 * miles OR

   C = 1.40 + .4M

b) C = 1.40 + .4M

    C = 1.40 + .4 * 8

    C = 1.40 + 3.20 = 4.60

c)  C <= 20 so

    20 <= 1.40 + .4M

    20 - 1.40 <= .4M

   18.60/.4 <= M

    46.5 <= M

Tom wins at chess 180 times in every 250.Daisy wins three quarters of the time.Jacob wins 328 times in every 400?Work out who has the best percentage score.

Answers

Daisy bc if you add up 250 plus three quarters is 325

Answer:

Jacob has the best percentage score of 82%

Step-by-step explanation:

Tom wins at chess 180 times in every 250

Daisy wins 3/4 of 180 times

Jacob wins 328 times in every 400

Tom's percentage score = [tex]\frac{180}{250} * 100[/tex] = 72%

Daisy wins [tex]\frac{3}{4} * 180 = 135[/tex] times

Daisy's percentage score = [tex]\frac{135}{250} * 100[/tex] = 54 %

Jacob's percentage score = [tex]\frac{328}{400} * 100[/tex] = 82%

∴ Jacob has the best percentage score.

Question 10: If the product of all the numbers from 1 to 100 is divisible by 2^n, then what is the maximum possible value for n: A. 128; B. 87; C. 64; D. 97; E. 70.

Answers

Answer: D

Step-by-step explanation:

100!=2*3*4*...*100

Counting which numbers are divisible by 2:

2,4,6,8,10,12,14,...,96,98,100 : 50 numbers (100/2=50)

Counting which numbers are divisible by 4=2²:

4,8,12,16,20,...96,100: 25 numbers (100/4=25)

Counting which numbers are divisible by 8=2³:

8,16,24,32,40,...,96: 12 numbers (100/8=12.5 ==> 12)

Counting which numbers are divisible by 16=2⁴:

16,32,48,...,96: 6 numbers (100/16=6.25 ==> 6)

Counting which numbers are divisible by 32=2⁵:

32,64,96 : 3 numbers(100/32=3.125 ==>3)

Counting which numbers are divisible by 64=2⁶:

64 : 1 number (100/64=1.5625 ==>1)

Sum of those numbers= 50+25+12+6+3+1=97

100! is divisible by 2⁹⁷.

Answer D

There are 50 even numbers - divisible by 2
There are 25 multiples of 4
There are 12 multiples of 8
There are 6 multiples of 16
There are 3 multiples of 32
There is one multiple of 64
Each of these is also counted in the line above

So the unique multiples are (1 x 64) x (2 x 32) x (3 x 16) x (6 x 8) x (13 x 4) x (25 x 2)
= (1 x 2^6) x (2 x 2^5) x (3 x 2^4) x (6 x 2^3) x (13 x 2^2) x (25 x 2^1)
So n = 6 + 10 + 12 + 18 + 26 + 25 = 97

The slow (but easier way) to see this is to write down all the even numbers in factors of 2 and count the number of 2S
Eg 2, 2x2, 2x3, 2x2x2, 2x5, 2x2x3, 2x7, 2x2x2x2, 2x9, 2x2x5, 2x11, 2x2x2x3, 2x13, 2x2x7, 2x15 etc

There are 35 houses in a neighborhood AT&T providers Internet service to 1/5 of the houses spectrum provides Internet service to 2/7 of the houses the remaining houses use hotspot as your Internet provider in this neighborhood how many houses use hotspot is there Internet provider

Answers

Total number of houses use hotspot is 18 houses

Step-by-step explanation:

Given that;

Number of total houses = 35

AT&T providers Internet service = [tex]\frac{1}{5}[/tex] of total house

Spectrum providers Internet service = [tex]\frac{2}{7}[/tex] of total house

Find:

Total number of houses use hotspot

Computation:

Number of houses AT&T providers Internet service = [tex]35 \times \frac{1}{5}[/tex]

Number of houses AT&T providers Internet service = 7

Number of houses Spectrum providers Internet service = [tex]35 \times \frac{2}{7}[/tex]

Number of houses Spectrum providers Internet service = 10

Total number of houses use hotspot = 35 - 7 - 10

Total number of houses use hotspot = 18 houses

Examine the graphs. Determine whether each function is discrete, continuous, or neither discrete nor continuous. Then state the domain and range of each function.

Answers

Hey there! I'm happy to help!

Discrete data are data that are usually counted and are represented by points that are not connected by a line.

Continuous data are data that are represented by a straight line.

Our graph has a continuous function because it is made of continuous.

In a function, the domain is all of the x-values and the range is all of the y-values.

With discrete data, the domain and range are usually more finite, and with continuous data, it is usually infinite.

What x-values on this graph include any possible number. If we follow the arrow on the bottom left side of our line, it will go down forever and go in the direction of infinitely many negative x-values. The same goes for the other direction with the other side of our arrow.

So, our domain is going to be -∞ ≤ x ≤ ∞.

If we look at our range, we have the same thing happening. We will have infinite negative y-values and infinitely positive as our arrow goes infinitely in both directions.

So, our range is going to be -∞ ≤ y ≤ ∞.

Step-by-step explanation:

Use the mid point formula and equate to each coordinate of the midpoint

with endpoints (x₁, y₁ ) and (x₂, y₂ ) then

midpoint = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

let S = (x, y) , then

[tex]\frac{x+0}{2}[/tex] = 1 ( multiply both sides by 2 )

x = 2

and

[tex]\frac{y+2}{2}[/tex] = - 2 ( multiply both sides by 2 )

y + 2 = - 4 ( subtract 2 from both sides )

y = - 6

Then S (2, - 6 )
