Help me please?? solve using proportion

gulaghasi [49]

Answer:

2 1/2 cups

Step-by-step explanation:

A proportion says the ratio of one thing to another is the same for different amounts. Here, we want cups, so we can use the proportion ...

cups/people = 2/12 = x/15 . . . . . where x is the number we want to find

Multiplying by 15 gives ...

x = 15(2/12) = 5/2 = 2 1/2

You will need 2 1/2 cups of zucchini to feed 15 people with the same recipe.

let a,b,c,d be four integers (not necessarily distinct) in the set {1,2,3,4,5}. the no. of polynomials x^4+ax^3+bx^2+cx+d which

Eddi Din [679]

By either long or synthetic division, it's easy to show that

$\dfrac{x^4+ax^3+bx^2+cx+d}{x+1}=x^3+(a-1)x^2+(-a+b+1)x+(a-b+c-1)-\dfrac{a-b+c-d-1}{x+1}$

The quartic will be exactly divisible by $x+1$ when the numerator of the remainder term vanishes, or for those values of $a,b,c,d$ such that

$a-b+c-d-1=0$

I'm not sure how to count the number of solutions (software tells me it should be 80), but hopefully this is a helpful push in the right direction.
