Step-by-step explanation:

A kennel owner has 400 feet of fencing to enclose a rectangular dog exercise pen. Express the area of the exercise pen, A, as a function of one of its dimensions, x. A(x) = x(x - 200) A(x) = x(x - 200) A(x) = x(400 - x) A(x) = x(400 - x) A(x) = x(200 - x) A(x) = x(200 - x) A(x) = (200 - x)2

Answers

Answer:

A(x) = x(200-x)

Step-by-step explanation:

400 feet of fencing to enclose a rectangular dog exercise pen means the perimeter of rectangle is 400 feet

If x is length and y is breadth. Perimeter is given by :

P = 2(x+y)

400 = 2(x+y)

⇒ (x+y) = 200 .....(1)

y = 200-x

Area of a rectangle is given by :

A = xy

A(x) = x(200-x)

Hence, the area as a function of length of rectangle is x(200-x).

Your friend says that there is an angle whose measure is the same as the measure of the sum of its supplement and its complement.

Is your friend correct? What is the measure of the angle?

Answers

Let's check:

Let the angle be x

It's complement is 90-x

It's supplement is 180-x

x = 90 - x + 180 - x

x = 270 - 2x

3x = 270

x = 90

So the angle is 90, it's complementary is 0 and it's supplementary is 90... so 90 = 0 + 90

A hotel manager found that his gross receipts for the day, including a 5% sales tax, were $1645.35. Find the amount of sales tax collected.

Answers

Answer:

The amount of sales tax collected is $78.35

Step-by-step explanation:

Percentages

The gross receipts for the day were $1645.35, including a 5% sales tax.

If a percentage is already included (added) to a certain quantity, then it's not the original quantity or 100%.

The problem states that the gross receipts already include a 5% sales tax, thus the receipts are 100+5=105% of the net sales.

This means the net sales were $1645.35 / 105 * 100 = $1567

Subtracting $$1645.35 - $1567 = $78.35 we get the amount of sales tax.

The amount of sales tax collected is $78.35

-6 - 13
I don’t get it can someone explain?

Answers

Subtracting a negative number is basically just addition. Think of it as 6+13, which would be 19.

Answer:

-19

Step-by-step explanation:

So, you can also write this equation as:

-6 + -13 = -19

For example:

You owe your friend $6.

You borrow 13 more dollars from him.

Now you owe him $19.

You have $-19 because you are in debt.

Answers

Answer:

932/1000

Step-by-step explanation:

To write .932 as a fraction you have to write .932 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

.932 = .932/1 = 9.32/10 = 93.2/100 = 932/1000

And finally we have:

.932 as a fraction equals 932/1000

Mr. Shaw graphs the function f(x) = -5x + 2 for his class. The line contains the point (-2, 12). What is the point-slope
form of the equation of the line he graphed?
Oy - 12 = -5(x + 2)
Oy - 12 = 2(x + 2)
O y + 12 = 2(x - 2)
O y + 12 = -5(x - 2)

Answers

Answer:

The first choice is correct. y-12=-5(x+2)

Step-by-step explanation:

Point-Slope Form of a Line

The point-slope form of the equation of a line is:

y-k=m(x-h)

Where m is the slope and (h,k) is a point through which the line passes.

The equation of the line in slope-intercept form is:

y=mx+b

Where b is the y-intercept.

Mr. Shaw graphs the function y=f(x)=-5x+2

The coefficient of the x can be identified as the slope m=-5. We are given the point (-2,12) to build the point-slope form of Mr. Shaw's line as follows:

y-12=-5(x+2)

The first choice is correct. y-12=-5(x+2)

O A. X-1
O B. X-5
O C. X+5
O D. x+1

Answers

The factor x + 1 is a factor of the trinomial expression 5x^2 + 20x + 15

How to determine the factor of the expression?

The expression is given as:

5x^2 + 20x + 15

Factor out 5 from the expression

5(x^2 + 4x + 3)

Expand

5(x^2 + x + 3x + 3)

Factorize the expression

5(x(x + 1) + 3(x + 1))

Factor out x + 1

5(x + 3)(x + 1)

The factors of the above expressions are 5, x + 3 and x + 1

Hence, x + 1 is a factor of the trinomial expression 5x^2 + 20x + 15

This equation represents the data:

2.5(12.75x + 24.50) = 188.75

Big Time Movers worked
hours on New Year’s Day.

Answers

The answer is:

x = 4hrs

Explanation:

2.5(12.75x + 24.50) = 188.75

31.875x + 61.25 = 188.75

31.875x = 188.75 - 61.25

31.875x = 127.50

x = 127.50/31.874

x = 4

The Montanez family is a family of four people. They have used 3,485.78 gallons of water so far this month. They cannot exceed 7,250.50 gallons per month during drought season. Write an inequality to show how much water just one member of the family can use for the remainder of the month, assuming each family member uses the same amount of water every month.

Answers

Answer: yes

Step-by-step explanation:

this month 3485.78/4 = 871.445 gallons per person

Drought month 7250.50/4 = 1812.625

difference 7250.50 - 3485.78 = 3764.72

Answers

Complete question :

The temperature at 5:00 a.m. was –6 °F. By 3:00 p.m., the temperature had risen to a high of 36 °F. If the temperature at 8:00 p.m. decreased from the high by the change in temperature in Fahrenheit degrees from 5:00 a.m. to 3:00 p.m., what was the temperature at 8:00 p.m.?

Answer:

-6°F

Step-by-step explanation:

Temperature at 5am (t1) = - 6°F

Temperature at 3pm (t2) = 36°F

Change in temperature, between 5am and 3pm:

(t2 - t1) = (36 - (-6)) = (36 + 6) = 42°F

Hence, temperature at 8:00 pm:

High temperature - change in temperature between (5am - 3pm)

36°F - 42°F = - 6°F
