What is n? Stick around for more points

amm1812

N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.

Here's how to use n in an algebraic equation:

5 + n = 12

To find what N represents, let it be the only thing on the left side of the variable:

5 -5 + n = 12 - 5

n = 7

Happy to help!

Ted is making trail mix for a party .He mixes 1/1/2cups of nuts,1/4 cup of raisins,and 1/4 cup of pretzels.How many cups of pret

balandron [24]

Answer:

1.875 or $1\frac{7}{8}$ cups of pretzel

Step-by-step explanation:

The number of cups needed is equivalent to the probability of pretzel in the mix times the number of cups in the mix.

-The probability of pretzel is :

$P(pretzel)=\frac{0.2}{0.25+0.25+1.5}\\\\=0.125$

We multiply this probability by the number of cups of the mix:

$=P(pretzel)\times (mix \ cups)\\\\=0.125\times 15\\\\=1.875 \ or \ 1\frac{7}{8}$

Hence, 1.875 or 1/7/8 cups of pretzel is needed.

What is the equation of the circle with center (0, 1) and a radius of 10?

victus00 [196]

Answer:

The equation of the circle with center (0, 1) and a radius of 10 is $\bold{x^{2} + y^{2} - 2y-99 = 0}$

Solution:

Equation of circle whose center (h, k) and radius r is given as,

$(x-h)^{2} + (y-k)^{2} = r^{2}$ ---- eqn 1

From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.

Hence we get, h = 0 ; k = 1; r = 10

By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as

$(x-0)^{2} + (y - 1)^{2} = 10^{2}$

On Simplifying we get

$x^{2} + (y-1)^{2} = 10^{2}$

Expand $(y-1)^{2}$ using the formula $(a-b)^{2} = a^{2} - 2ab + b^{2}$

$x^{2} + y^{2} - 2y + 1 = 10^{2}$

$x^{2} + y^{2} - 2y + 1 = 100$

$x^{2} + y^{2} - 2y + 1-100 = 0$

$x^{2} + y^{2}- 2y- 99 = 0$

Hence equation of the circle with center (0, 1) and a radius of 10 is $\bold{x^{2}+y^{2}-2 y-99=0}$
