Mr. Brown's class has 20 students. 6 of the students have blonde hair. What
percent of the students have blonde hair?

Answer: 5/3

Step-by-step explanation:

The scale factor is the same as the ratio of the length of a side of the image to the length of the corresponding side in the preimage.

We know that N'Q'=10 and NQ=6, so the scale factor is 10/6 = 5/3.

The equation of line passing through point (6,0) and having a slope of -5/6 is y = -(5/6)x + 5

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point: (6,0)

First, we determine the y-intercept by substituting the given values into the equation of line formula and solve for b.

y = mx + b

0 = (-5/6)6 + b

0 = -5 + b

b = 5

Now that the values of slope m ( -5/6 ) and y-intercept b ( 5 ) is known, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = (-5/6)x + 5

y = -(5/6)x + 5

Therefore, the linear equation of the line is y = -(5/6)x + 5.

Answer:

92 men

Step-by-step explanation:

First, since they give you the total employees, you need to add the ratios together to get a total.

4 + 7 = 11

Next, setup a proportion using men to total employees.

[tex]\frac{4}{11}=\frac{m}{253}[/tex]

The left side is the ratio and the right side is the actual. m will represent the total number of men employed.

Cross multiply then divide.

4 x 253 = 1012

11 x m = 11m

11m = 1012

11m/11 = 1012/11

m = 92

The sale price of the magazine subscription is $11.55

From the question, the given parameters are:

Subscription = $35

Discount = 67% off

The sale price of the magazine subscription is then calculated as

Sales price = Subscription x (1 - Discount)

Substitute the known values in the above equation

So, we have the following equation

Sales price = 35 x (1 - 67%)

Evaluate the product

Sales price = 11.55

Hence, the sales price is $11.55

On average, the bear's weight change per month was 8.6 pounds.

The average is the mean value in a data set.

We compute the average by adding the data values and dividing by the number of items in the data set.

In this scenario, the average weight loss per month offers an idea of the weight change the bear experienced during the 7¹/₂ months.

The number of months during hibernation = 7¹/₂ or 7.5 months

The total weight loss = 64.5 pounds

The average weight change per month = 8.6 pounds (64.5/7.5)

Thus, we can conclude that, on average, the bear experienced a weight loss of 8.6 pounds per month and reduced by a total of 64.5 pounds in 7¹/₂ months.

The range of the function  f(x) = |x| − 5 is −5 ≤ y < ∞.

Given the function is  f(x) = |x| − 5

we know the domain is (−∞,∞)

therefore from the domain we calculate the range as:

−5 ≤ y < ∞.

A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values.

All real numbers are defined by the function y=|ax+b|. Consequently, the set of all real numbers is the domain of the absolute value function. Every time a number has an absolute value, it has a positive value. The range of an absolute value function with the form y= |ax+b| is hence y R | y 0.

Hence we get the required range if the function.

Answer:

hello Your answer is down below

Step-by-step explanation:

The Question given "What is the range of f(x) = |x| − 5?"

The answer choices:

−∞ < y ≤ −5

−5 ≤ y < ∞

0 ≤ y < ∞

5 ≤ y < ∞

So what do we know? hmm: The definition of Function range is: "The set of values of the dependent variable for which a function is defined".

So the range of: [tex]\mathrm{Range\:of\:}\left|x\right|-5\\[/tex]  is f(x) ≥ -5.

Which would mean the Interval Notation                Oh yeah btw the answer is −5 ≤ y < ∞

If QR = 6x, RS = 10 and QS = 5x+13, then the length of the line QS is 28 units.

The length of the line QR = 6x

The length of the line RS = 10

The length of the line QS = 5x+13

We know

The length of the line QS = The length of the line QR + The length of the line RS

Substitute the values in the equation

5x+13 = 6x + 10

Move the 6x to the left hand side of the equation and move 13 to the right hand side of the equation

5x-6x = 10-13

Subtract the terms

(5-6)x = 10-13

-1x = -3

x = 3

Then the length of the QS = 5x+13

Substitute the value of x in the equation

The length of the line QS = 5×3+13

= 15+13

= 28 units

Hence, if QR = 6x, RS = 10 and QS = 5x+13, then the length of the line QS is 28 units

$7.99 is the constant of proportionality in this relationship.

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. The relationship between two quantities is constant for all values when they are proportional, which indicates that as one quantity rises, the other rises as well. An illustration would be the ratio of a circle's circumference to its diameter, which is equal to pi.
