It depends on the value of x, however, when we do not know the value of x, we simply skip the multiplication step. Without that, the answer would be 22x. Hope this helps!

david quiere saber cuanto requiere invertir mensualmente para obtener $30,760.08 durante 6 meses si los invierte con el 12% capi

Akimi4 [234]

Answer:

A = $32,652.44

Step-by-step explanation:

Given: Principal (P) = 30,760.08, Annual Rate (R) = 12%, Time (t in years) = 0.5

To find: How much David needs to invest monthly

Formula: $A = P(1 + r/n)^n^t$

Solution: To find, simply add principal + interest

First, convert R as a percent to r as a decimal

r = R/100

r = 12/100

r = 0.12 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 30,760.08(1 + 0.12/12)(12)(0.5)

A = 30,760.08(1 + 0.01)(6)

A = $32,652.44

Therefore;

The total amount David will obtain with 30,760.08 for 6 months, 12%is $32,652.44.

If you have $45 and they take 2.1% of it how much do you have left ?

IRINA_888 [86]

First you need to make a multiplier for 100-2.1%, to do this you minus the values and divide it by 100:
100-2.1 = 97.9
97.9/100 = 0.979

Then you multiply all the questions by it:
$45 * 0.979 = $44.055
$765 * 0.979 = $748.935
$1300 * 0.979 = $1272.7

Hope this helps! :)

R(x)=2√x s(x)=√x (r/s)(3)

anygoal [31]

This is a trick question. First just understand that any number over itself is 1 so $\frac{2 \sqrt{x} }{\sqrt{x}}$ is just $2 * \frac{ \sqrt{x} }{ \sqrt{x}} = 2$ so it is just 2
