So we need to start by finding the total price which would be $150 because $130 + $20 would equal $150. Next thing we need to do is find out how many people we have and we have 5 people. We can figure that out by seeing it states “Dolores and four friends” which indicates there is 1 + 4 which would equal 5 then we would divide these 2 numbers we came up with ($150/5) to get $30 each person. Each person paid $30 for the buffet.

How might this number be shown on a calculator?<br> 5.31x1037 (37 is above 10)<br> [?]e[ ]
Arisa [49]

Answer:

5.31E37

Step-by-step explanation:

Given

5.31 * 10^{37}

Required

How it'd be displayed on a calculator

Standard calculators, today are built to always convert huge numbers or extremely small number to scientific notations;

This was done to allow the calculator fit each values on its screen

5.31 * 10^{37} is such a big number that it'll require the calculator to display it using scientific notations;

So, basically we have to convert 5.31 * 10^{37} to scientific notaton;

This is achieved by replacing *10^{37} with E37

So, 5.31 * 10^{37} is equivalent to 5.31E37

and there are 6 hours left 

so he spent 6 hours building a sandcastle

Part A: The area of a square is (9x2 − 12x + 4) square units. Determine the length of each side of the square by factoring the a
Sladkaya [172]

Answer:

Part A: The length of each side is 3x-2 units long.

Part B: The dimensions are 5x-4 and 5x+4 units long.

Step-by-step explanation:

Part A:

--> 9x^2-12x+4

--> Multiply 9 times 4 to see the factors of that product

--> 9 times4 = 36

Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36

Use the factor 6 and make it negative so -6

add another -6

Keep in mind that it is -6x

--> 9x^2-6x-6x+4

Separate the four terms into two different binomials

--> 9x^2-6x  and -6x+4

Factor the binomials

With 9x^2-6x you can factor a 3x

So it will 3x(3x-2)

Do the same thing with -6x+4

You can factor out a -2

-2(3x-2)

The reason you factor out a -2 and not 2 is because it has to be same so in this case it is (3x-2)

Take the two numbers that you factored and put them to make an expression so (3x-2)

--> (3x-2)(3x-2) or (3x-2)^2

3x-2 is the length of each side so it is 3x-2 units long

Part B:

-->25x^2-16y^2

Use the difference of squares

take the square root of 25x^2

that is 5x

take the square root of 16y^2

that is 4y

write it in this way (5x+4y)(5x-4y)

These are the dimensions of the rectangle
