If 160,000 divided by n = 4, find n

1 answer:

8 0

N = 40,000

To find the value of n, you want it to be on one side of the equation, and you want all the numbers to be on the other side. Starting out, this equation reads:

160,000/n = 4.

First, to get n out of the denominator (or bottom of the fraction), multiply both sides by n. On the left side, this will cancel out, leaving only 160,000. On the right side, you will now have 4n. So the equation should read:

160,000 = 4n.

To get n by itself, divide by 4 on both sides, leaving you with 40,000 = n.

Find the zeros of the function.<br> f(x) = 3x2 – 8x – 16

Vlad1618 [11]

Answer:

amusing you mean 3x^2-8x-16 the answer is when x is equal to -4/3 and 4

Step-by-step explanation:

3x^2-8x-16 ------> (3x+4)(x-4)

3x+4=0 ----> 3x=-4 ----> x=-4/3

x-4=0 ----> x=4

You can solve this by using "similar triangles".

In triangle ABC, we are looking for side AC which is x. Side AC is similar to side DF in triangle EDF.

You can solve for side x by picking two sides in triangle ABC and their corresponding sides in triangle EDF. This is what I mean:
$\frac{AC}{BC} = \frac{DF}{EF}$
Substitute for the values of AC, BC, DF and EF:
$\frac{x}{4} = \frac{11}{8} \\ \\ 8x = 4 \times 11 \\ \\ x = \frac{44}{8}$
$x = 5.5 \: units$
To solve for y, do the same thing. Pick two sides on triangle ABC and their corresponding sides in triangle DEF.
$\frac{AB}{BC} = \frac{DE}{EF}$
Substitute for the values and solve:
$\frac{3}{4} = \frac{y}{8}$
$4y = 24 \\ \\ y = 6 \: units$

We have the value x to be 5.5 units and y to be 6 units.
