Answer:

321 remainder 3

Step-by-step explanation:

The remainder of 7,707 ÷ 24  is 3

When we want to prove some properties of modular arithmetic we often make use of the quotient remainder theorem. It is a simple idea that comes directly from the long division. Given any integer A and a positive integer B, there exist unique integers Q and R such that

A= B * Q + R where 0 ≤ R < B

Given here 7,707 ÷ 24  this can be written as follows:

7707 = 321×24 + 3

Thus comparing with the above equation we get the remainder as 3

Hence the required form is  7707 = 321×24 + 3

Answer:

omg whats the answer

Step-by-step explanation:

Step-by-step explanation:

First, you want to start by creating an equation to find the unit rate

calculators = c

9c = 96.30

Solve!!!

9c/9 = 96.3/9

c= 10.7

A calculator costs $10.70 (Sorry I will be using the dollar sign instead)

Now you want to set an expression for 13 calculators

13c

Substitute 10.7 in

13(10.7)

Multiply them

$139.10

13 calculators cost $139.10

Answer:

b is 8√3 ⇒ A

Step-by-step explanation:

In the given triangle

∵ The Δ is the special right triangle 30°: 60°: 90°

∴ There is a ratio between its sides

∵ a is opposite to the angle of measure 30°

∵ b is opposite to the angle of measure 60°

∵ c is opposite the angle of measure 90°

∴ a: b: c = 1: √3: 2

∵ c = 16

→ By using the ratio between its sides

→ 30°: 60°: 90°

→  1    : √3:  2

→  a   : b   :  16

→ By using cross multiplication

∵ b × 2 = √3 × 16

∴ 2b = 16√3

→ Divide both sides by 2

∴ b = 8√3

Step one:

given data

we are told that the cost of the box of gulf is $9.30

and there are 18 golf balls in the box

Required:

we are to determine the cost of each ball

the cost is

Step two:

Cost per ball= total cost of the box/number of ball

Answer:

62% and 64%

Step-by-step explanation:

no computer access = 21 + 165 = 186/300 = 0.616 = 62%

no email access = 27 + 165 = 192/300 = 0.64 = 64%

Answer:

(a)  62%

(b)  64%

Step-by-step explanation:

To find the answer to part "a" you need to divide the total number of shoppers without computer access at home by the total number of shoppers (300).

186/300 = 0.616 = 0.62

0.62 is equivalent to 62%

To find the answer to part "b" you need to divide the total number of shoppers without an email account (Regardless of computer access) by the total number of shoppers (300).

192/300 = 0.64

0.64 is equivalent to 64%.

Answer:

Reflection across the x-axis: y = − f ( x ) y = -f(x) y=−f(x) The concept behind the reflections about the x-axis is basically the same as the reflections about the y-axis. The only difference is that, rather than the y-axis, the points are reflected from above the x-axis to below the x-axis, and vice versa.

the equation for g(x) after reflected over x axis and translated 4 units left

[tex]g(x)=-(x+4)^2[/tex]

Given :

Parent function is [tex]f(x)=x^2[/tex]

When a graph is reflected over x-axis then f(x)=-f(x)

When a graph is translated 'a' units left then we add 'a' with

f(x) becomes f(x+a)

Parent function f(x) is reflected over x-axis , multiply -1 with f(x)

so , [tex]f(x)=-x^2[/tex]

Now we translate 4 units to the left, add 4 with x

[tex]g(x)=-x^2\\g(x)=-(x+4)^2[/tex]

The final equation of g(x) is

[tex]g(x)=-(x+4)^2[/tex]

Answer:

y=-2+1

Step-by-step explanation:

Answer:

Let the tens digit of the required number be x and the units digit be y. Then,

x+y=12 .........(1)

Required Number = (10x+y).

Number obtained on reversing the digits = (10y+x).

Therefore,

(10y+x)−(10x+y)=18

9y−9x=18

y−x=2 ..........(2)

On adding (1) and (2), we get,

2y=14⟹y=7

Therefore,

x=5

Hence, the required number is 57.

Step-by-step explanation:

Hope it is helpful...

Step-by-step explanation:

Let X be the 1st digit and Y be the 2nd digit of the two digit number.

We have X * Y = 12 and (10X + Y) = (10Y + X) + 9.

=> XY = 12 and 9X = 9Y + 9

=> XY = 12 and X = Y + 1

Therefore X = 4 and Y = 3. => Number is 43.

Step-by-step explanation:

because if its half it will take twice as long

Answer:

44 hours

Step-by-step explanation:

If you decrease the amount of participants in half, the amount of time that it takes per work load automatically doubles. So if the original amount of hours that it took with six participants is 22. If we cut six into half, then 22 hours would double into 44. Then it would become 44 hours with three people. Also, for check, I did have this problem for RSM.

Answer:4 100/477

Step-by-step explanation:You need to divide it.And first you change the mixed numbers 27 8/9 and  6 5/8 to improper fraction .27 8/9 as a improper fraction is 251/ 9 . 6 5/8 as a improper fraction is  53/ 8 .ANd now you divide 251/ 9  by 53/ 8.In order to divide fractions you need to do KCF which stand for Keep ,change,flip .SO you have 251/ 9  divide 53/ 8  ,now you KEEP 251/9 ,Change the division sign to multiplication ,and flip 53/8 to 8/53.And now you multiply  251/9 by 8/53 which gives you 2008/ 477.Lastly you change 2008/ 477 which is a improper fraction to a mixed number which is 4 100/477.

1) function  2) not a function

the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.  

the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.

the coordinates for the second one are:

(2,5); (1,1); (1,2); (3,2)

and a function cannot have two same x-coordinates. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function

The horizontal line

Step-by-step explanation:

Answer:

Step-by-step explanation:

On the other hand, the vertical line has an undefined slope.

Slope is rise/run or change n y over change in x.

If the y axis coordinate never changes, then rise = 0. The only number that changes is x. x changes 1 for every 0 y changes. 0/1 = 0.

In a vertical line, however, the x coordinate is the one that doesn't change. We reverse the number from before, but we have a problem 1/0 is an undefined number since you cannot divide by 0.
