Mike and Joey bought identical loaves of bread and packages of bologna. Mike made sandwiches with 5 slices of bologna and had 4
Sedaia [141]

Answer:

Mike had 14 slice of bread in his loaf while

Joey had 8 slice of bread in his loaf.

Step-by-step explanation:

We should note that a sandwich is made up of two slice of bread.

that is :

A Sandwich = 2 Slice of bread

and for bologna to be in a sandwich, you will have 2 slice of bread together.

So, For Mike,

2 slice of bread × 5 Sandwich = 10 Slice of bread

Remaining Slice of bread = 4 Slice

Total Slice of bread in Mike loaf = 10 + 4

= 14 slice of bread was in Mike loaf of bread.

For Joey

A sandwich = 2 Slice of bread

2 slice of bread × 4 Sandwich = 8 Slice of bread

Remaining slice of bread = 0

Total slice of bread in joey loaf = 8 slice of bread.

John has to build a box for his scouting project with a volume of 36 cubic centimeters.
prohojiy [21]

Answer:

John should build the box 3 cm high.

Step-by-step explanation:

John should build the box 3 cm high because to find the volume you must do length x width x height. To find this you have to multiply the length x width. In this problem 6 would be the length and 2 would be the width. After multiplying those you get 12. You then have to find what number multiplies with 12 to get 36, which is 3. Hope this helped!

What is the factorization of 729^15+1000?
igomit [66]

Answer:

The factorization of 729x^{15} +1000 is (9x^{5} +10)(81x^{10} -90x^{5} +100)

Step-by-step explanation:

This is a case of factorization by <em>sum and difference of cubes</em>, this type of factorization applies only in binomials of the form (a^{3} +b^{3} ) or (a^{3} -b^{3}). It is easy to recognize because the coefficients of the terms are <u><em>perfect cube numbers</em></u> (which means numbers that have exact cubic root, such as 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000, etc.) and the exponents of the letters a and b are multiples of three (such as 3, 6, 9, 12, 15, 18, etc.).

Let's solve the factorization of 729x^{15} +1000 by using the <em>sum and difference of cubes </em>factorization.

1.) We calculate the cubic root of each term in the equation 729x^{15} +1000, and the exponent of the letter x is divided by 3.

\sqrt[3]{729x^{15}} =9x^{5}

1000=10^{3} then \sqrt[3]{10^{3}} =10

So, we got that

729x^{15} +1000=(9x^{5})^{3} + (10)^{3} which has the form of (a^{3} +b^{3} ) which means is a <em>sum of cubes.</em>

<em>Sum of cubes</em>

(a^{3} +b^{3} )=(a+b)(a^{2} -ab+b^{2})

with a= 9x^{5} y b=10

2.) Solving the sum of cubes.

(9x^{5})^{3} + (10)^{3}=(9x^{5} +10)((9x^{5})^{2}-(9x^{5})(10)+10^{2} )

(9x^{5})^{3} + (10)^{3}=(9x^{5} +10)(81x^{10}-90x^{5}+100)
