Salma made 378 for 18 hours of work.
At the same rate, how much would she make for 5 hours of work?

Answer:

perimeter = 16x+9x+8x+11

simplified perimter = 33x+11

Step-by-step explanation:

this isnt even close to 100 pts but okay

Answer:

a. 16x + 9x + 8x + 11

b. 33x + 11 (or 11(3x + 1) if this is asking for a factored expression)

Step-by-step explanation:

Looking at the directions, part a tells us to use all 4 side lengths, so the equation for part a is 16x + 9x + 8x + 11.

Now to simplify that expression.

16x + 9x + 8x + 11

Step: Combine 16x, 9x, and 8x. I'll go from left to right.

25x + 8x + 11

33x + 11

(What you see above this statement is my answer, but work is below if this is asking for a factored expression.)

11: 1, 11

33: 1, 3, 11, 33

Now divide both 33x and 11 by 11 and put the 11 outside the parentheses.

33x/11 = 3x

11/11 = 1

11(3x + 1)

Answer:

(1165, 1235) (hours)

Step-by-step explanation:

The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:

(1200 - 35, 1200 + 35), or

(1165, 1235) (hours)

This is an application of the Empirical Rule.

The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.

With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.

The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:

The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;

(1200 - 35)=1165

( 1200 + 35)=1235

(1165, 1235) (hours)

Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

Determine the other zero

The zeros can be represented as:

[tex]x_1 = -2[/tex]

[tex]x_2 = -6[/tex]

[tex]x_3 = -5-i[/tex]

Considering the 3rd zero, which is a complex number.

If a polynomial has a complex number as one of its zeros, then its conjugate pair is the corresponding zero

A conjugate pair is given as:

[tex]a + bi[/tex] and [tex]a - bi[/tex]

For [tex]x_3 = -5-i[/tex]

The conjugate pair is:

[tex]x_4 = -5 + i[/tex]

132 units squared

Step-by-step explanation:

To start we can find the area of the rectangle, to do that we need to do

12*6=72

then we can find the area of the triangle, the formula to find a triangle's area of (b*h)/2, so we can do that

(10*12)/2=60

then we can add them together

72+60=132

Answer: 90

Step-by-step explanation:

Triangle=60

square=36

Now add them!

Answer:

Step-by-step explanation:

A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)

For example:

[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .

If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis

However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.

At a concert 3 out of 10 people who entered the Alamodome wore Nike shoes based on this information if there are 1200 people at the music concert how many people could be expected to be wearing Nike shoes?

Answer:

360 people

Step-by-step explanation:

The fraction of people wearing Nike shoes = 3/10

The total number of the people at the concert = 1200 people

Therefore, the number of people cthat ould be expected to be wearing Nike shoes is calculated as:

3/10 × 1200 people

= 360 people

The answer is 360 people

Answer:

x = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (9[tex]\sqrt{2}[/tex] )²

2x² = 162 ( divide both sides by 2 )

x² = 81 ( take the square root of both sides )

x = [tex]\sqrt{81}[/tex] = 9

Answer

[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]

Step by Step Explanation

Given

See attachment for table

Required

Determine the sinusoidal function

The sinusoidal function is represented as:

[tex]y = A \sin(Bx + C) + D[/tex]

Where

[tex]|A| = Amplitude[/tex]

And it is calculated as:

[tex]A = \frac{1}{2}[Highest - Least][/tex]

From the table:

Highest = 77 and Least = 21

So:

[tex]A = \frac{1}{2}[77 - 21][/tex]

[tex]A = \frac{1}{2}[56][/tex]

[tex]A = 28[/tex]

B is calculated as:

[tex]Period = \frac{2\pi}{B}[/tex]

The period is 12 i.e. 12 months

So:

[tex]\frac{2\pi}{B} = 12[/tex]

[tex]B = \frac{2\pi}{12}[/tex]

[tex]B = \frac{\pi}{6}[/tex]

C is calculated as:

[tex]\frac{C}{B} = -4[/tex]

[tex]C = -4 * B[/tex]

[tex]C = -4 * \frac{\pi}{6}[/tex]

[tex]C = -2 * \frac{\pi}{3}[/tex]

[tex]C = -\frac{2\pi}{3}[/tex]

Lastly, D is calculated as:

[tex]D = Least + A[/tex]

So:

[tex]D =21 + 28[/tex]

[tex]D=49[/tex]

So, the function is:

[tex]y = A \sin(Bx + C) + D[/tex]

[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]

Answer:

y=28 sin (pi/6 t - 7pi/6)+49

Step-by-step explanation:

Answer:

scale factor = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

The scale factor is the ratio of corresponding sides , B  to A

scale factor = [tex]\frac{50}{30}[/tex] = [tex]\frac{5}{3}[/tex]

Then

[tex]\frac{x}{15}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

3x = 75 ( divide both sides by 3 )

x = 25

and

[tex]\frac{18}{y}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

5y = 54 ( divide both sides by 5 )

y = 10.8
