If the mean of 5 positive integers is 15, what is the maximum possible difference between the largest and the smallest of these

5 numbers?

Answer:

64

Step-by-step explanation:

If the mean is 15, the sum of 5 numbers is:

5*15 = 75

Minimum value for the first four numbers would be:

1, 2, 3, 4

Then the fifth number is:

75 - (1+2+3+4) = 75 - 10 = 65

So the maximum difference is:

65 - 1 = 64

The number of calories K is needed each day by a moderately active women who weight w pounds, is h inches tall, and is a year ol

drek231 [11]

K = 917 + 6(w + h - a)
k = 1925
w = 119
a = 25

1925 = 917 + 6(119 + h - 25) =
1925 = 917 + 6(h + 94)
1925 = 917 + 6h + 564
1925 = 1481 + 6h
1925 - 1481 = 6h
444 = 6h
444/6 = h
74 = h........she is 74 inches tall

Multiply the trinomial x^2+xy+y^2 times the binomial x-y and simplify.

Natalija [7]

Multiply then simplify, that's doing the same work twice...anyway

x^3+x^2y+xy^2-x^2y-xy^2-y^3

x^3-y^3 which if factored is:

(x-y)(x^2+xy+y^2) which is what you started with :)

Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x2 + 48x + 24

ludmilkaskok [199]

For this case we have the following polynomial:

$60x ^ 2 + 48x + 24$

What we must do for this case is to factor the polynomial, so that we have:

1) The number of bottles

2) the weight of each bottle.

We have then:

$12 (5x ^ 2 + 4x + 2)$

Answer:

A factorization that could represent the number of water bottles and weight of each water bottle is:

$12 (5x ^ 2 + 4x + 2)$

Determine the value of x and y in the following systems of equations5x-2y=4 ; -2x+y=2.

V125BC [204]

Answer:(x,y)=(8,18)

Step-by-step explanation:

Given

5x-2y=4-------1

Second Equation

-2x+y=2-----2

Now multiply equation 2 by 2 and it to equation 1

5x-4x+0=8

x=8

substitute it in equation 1

$5\times 8-2\times y=4$

36=2y

y=18

Therefore

(x,y)=(8,18)
