Answer:

70.

Step-by-step explanation:

Given : 5,514÷82

To find : use compatible numbers to estimate the quotient .

Solution : We have given 5,514÷82

Step 1: Find compatible numbers.

Compatible number : Compatible numbers are numbers that are close to the numbers they're replacing that divide evenly into each other.

Here, 5, 514

Estimate of 5, 514 is 5600.

Now estimate of 82 is 80.

Step 2: Divide the 5600 ÷ 80.

Step 3 : Cancel out zeroes

560 ÷ 8.

70.

So, the estimate of 5,514÷82 is 70.

Therefore, 70.

Heron wants to buy a video game. The price is regularly priced at 55 dollars. The store has a discount of 20% off and a sales ta

seropon [69]

The amount paid by Heron for the video game is $46.64.

Step-by-step explanation:

Here, the marked price of the video game = $55

The discount percentage on the video game = 20%

Calculating 20% of the $55, we get:

$\frac{20}{100} \times 55 = 11$

So, the discount offered on the video game = $11

Selling Price = Marked Price - Discount

=$55 - $11 = $44

Now, the tax percentage on the video game = 6%

Calculating 6% of the $44, we get:

$\frac{6}{100} \times 44 =2.64$

So, the tax on the video game = $2.64

New Selling Price = Selling Price + Tax

=$44 + $2.64 = $46.64

So, the amount paid by Heron for the video game is $46.64.

Mr. Chen is painting one wall of a room in his attic. He needs to detemine the area of the wall so he will know how much paint h

MAVERICK [17]

Area of the figure

= (area of rectangle) + (area of triangle)

= (8 × 10) + (½ × 4 × 8)

= 80 + 16

= 96

Area = 96ft²

Quarts of paint needed

= 96/22

= 48/11

= 4.36

Mr. Chen will have to buy 5 quarts of paint.

Determine n between 0 and 19 such that (2311)(3912) ≡ n mod 20.

sleet_krkn [62]

You can write 2311 and 3912 in the form $20q+r$ :

$2311=115\cdot20+11$

$3912=125\cdot20+12$

Then

$2311\cdot3912=(115\cdot20+11)(125\cdot20+12)$

$2311\cdot3912=115\cdot125\cdot20^2+(11\cdot125+12\cdot115)\cdot20+11\cdot12$

Taken modulo 20, the terms containing powers of 20 vanish and you're left with

$2311\cdot3912\equiv11\cdot12\equiv132\pmod{20}$

We further have

$132=6\cdot20+12$

so we end up with

$2311\cdot3912\equiv12\pmod{20}$

and so $n=12$ .

###

If instead you're trying to find $2311^{3912}\pmod{20}$ , you can apply Euler's theorem. We can show that $\mathrm{gcd}(2311,20)=1$ using the Euclidean algorithm. Then since $\varphi(20)=8$ , and 8 divides 3912, we have

$2311^{3912}\equiv2311^{489\cdot8}\equiv(2311^{489})^8\equiv1\pmod{20}$

To show 2311 and 20 are coprime:

2311 = 115*20 + 11

20 = 1*11 + 9

11 = 1*9 + 2

9 = 4*2 + 1 => gcd(2311, 20) = 1

What is the slope of the line on the graph below? A. -1/2 B. 1/2 C. 1 D. 2

WINSTONCH [101]

Answer: choice D) the slope is 2

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

Work Shown:

Pick any two points on the line. I'm going to pick (0,1) and (1,3)

Label these two points as (x1,y1) and (x2,y2).
So,
(x1,y1) = (0,1) meaning that x1 = 0 and y1 = 1
(x2,y2) = (1,3) meaning that x2 = 1 and y2 = 3

Now use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (3-1)/(1-0)
m = 2/1
m = 2

Going from (0,1) to (1,3) we move 2 units up and 1 unit to the right.
The "2 units up" is the "rise"
The "1 unit to the right" is the "run"

Slope = rise/run = (change in y)/(change in x)
