A recipe that makes 4 servings calls for 2/3 cup of flour. How much flour is required to make 20 servings? 6 cups 3/1/3 cups 2/3
sergeinik [125]

20 servings / 4 servings = 5 times as much.

Multiply the amount needed for 4 servings by 5:

2/3 cups x 5 = 10/3 = 3 1/3 cups total

Mohamed and Li Jing were asked to find an explicit formula for the sequence -5\,,-25\,,-125\,,-625,...−5,−25,−125,−625,...Minus,
Nataly [62]

Answer:

Li Jing

Step-by-step explanation:

Given the sequence:

-5,-25,-125,-625,...

Mohamed's Formula is given as: g(n)=-5\cdot5^{\large{n}}

Using Mohamed's formula:

When\: n=1,g(n)=-5\cdot5^{\large{n}}=-5\cdot5^{1}=-25\\When\: n=2,g(n)=-5\cdot5^{\large{n}}=-5\cdot5^{2}=-125\\

Li Jing's Formula is given as: g(n)=-5\cdot5^{\large{n-1}}

Using Mohamed's formula:

When\: n=1,g(n)=-5\cdot5^{\large{n-1}}=-5\cdot5^{1-1}=-5\\When\: n=2,g(n)=-5\cdot5^{\large{n-1}}=-5\cdot5^{\large{2-1}}=-25\\

We can see that Li Jing's Formula produces the gien sequence.

Li Jing is Right.

PLEASE HELP! <br> Will try to give the brainliest!
dusya [7]

Answer:

L: (15+6x) W: 2

L: (10+4x) W: 3

L: (5+2x) W: 6

Step-by-step explanation:

We don't have any numbers here to do calculations, so probably this is just an exercise in FACTORING. Also to practice that area is length times width.

The area given,

30 + 12x

can be factored several ways to be able to fill in the table.

This kind of factoring is like "un-distributive property" where a common factor can be factored out of the expression. Usually its helpful to factor out the greatest common factor (GCF) but in this case any common factor will do.

Also, unless there are more directions, either factor may be the length or the width.

2(15+6x)

3(10+4x)

6(5+2x)

What is the discriminant of the quadratic equation 0 = 2x2 3x – 5?
a_sh-v [17]
If you would like to find the discriminant of the quadratic equation 0 = 2x^2 + 3x - 5, you can do this using the following steps:

<span>0 = 2x^2 + 3x - 5
0 = ax^2 + bx + c
a = 2, b = 3, c = - 5

</span>D = b^2 - 4 * a * c = 3^2 - 4 * 2 * (-5) = 9 + 40 = 49

The correct result would be 49.
