Express x% of 4 plus y% of 5 as a percentage of 11

1 answer:

4 0

X% of 4 = x*4/100 = 0.04x

y% of 5 = x*5/100 = 0.05y

x% of 4 + y% of 5 = 0.04x + 0.05y

How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %

Then make n = 0.04x + 0.05y

9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%

The vertex of the function is:

(-2,-2)

<h2>Step-by-step explanation:</h2>

We are given a absolute value function f(x) in terms of variable "x" as:

$f(x)=-|x+2|-2$

We know that for any absolute function of the general form:

$f(x)=a|x-h|+k$

the vertex of the function is : (h,k)

and if a<0 the graph of function opens downwards.

and if a>0 the graph of the function opens upwards.

Hence, here after comparing the equation with general form of the equation we see that:

a= -1<0 , h= -2 and k= -2

Since a is negative , hence, the graph opens down .

Hence, the vertex of the function is:

(-2,-2)

During a period of 112 minutes, a music station played 40 minutes of commercials. What

Gemiola [76]

Answer:

9:5

Step-by-step explanation:

112 - 40 = 72. 112 represents the total time, but you are comparing music to commercials, so you have to subtract the commercial time from the total time.
Find the GCF of 72 and 40, which is 8.
Divide 72 and 40. The simplified ratio is 9:5.

Guys pls help me im failing my grade and i really need help plsssss and dont do it for the points

Nataliya [291]

Answer:

simplified: $\frac{3}{5}$

unsimplified: $\frac{12}{20}$

Step-by-step explanation:

Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:

15 - 3 = 12

The difference of the two fractions is $\frac{12}{20}$ . To simplify this answer, divide both the numerator and the denominator by 4:

12/4 = 3

20/4 = 5

The difference in simplified form is $\frac{3}{5}$ .

I hope this helps. :)

Solve quadratic formulax^2-4x+3=0

bekas [8.4K]

The general formula for a equation of the form:

$ax^2+bx+c=0$

is:

$x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$

In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:

$\begin{gathered} x=\frac{-(-4)\pm\sqrt[]{(-4)^2-4(1)(3)}}{2(1)} \\ =\frac{4\pm\sqrt[]{16-12}}{2} \\ =\frac{4\pm\sqrt[]{4}}{2} \\ =\frac{4\pm2}{2} \end{gathered}$

then:

$x_1=\frac{4+2}{2}=\frac{6}{2}=3$

and

$x_2=\frac{4-2}{2}=\frac{2}{2}=1$

Therefore, x=3 or x=1.

Answer:

53 shares

Step-by-step explanation:

If we assume the price remained constant, then the number of shares increased by 6%.

(50 shares)(1 +6%) = 53 shares

The man then owned 53 shares.
