Ms.Maxwell bought a purse with 1/4 of her money. The purse cost $37.00. How much money did Ms.Maxwell have left after she bought the purse?

Answers

Answer:

the money left after purchasing the purse is $111

Step-by-step explanation:

The computation of the money left after purchasing the purse is given below:

Since in the question it is mentioned that she bought a purchase with one-fourth of money

And, the purse cost is $37

So the amount left would be

= $37 × (3 ÷ 4) ÷ (1 ÷ 4)

= $37 × 0.75 ÷ 0.25

= $111

Hence, the money left after purchasing the purse is $111

Answers

Answer:

Option D : Undefined

Step-by-step explanation:

Given points (-5,8) and (-5,3) lies on a line.

Slope of a line is given by:

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{3-8}{-5-(-5)}\\\\m=\frac{-5}{0}[/tex]

Anything divided by zero is undefined.

Therefore,

Option D is the correct answer.

Is there a way to quickly find a function if you have a handful of ordered pairs?
ex. (-6, 10) (-4, 7) (-2, 4) (0, 3) (2, 0) (4, -3)

Answers

Yeah. You basically have to look at every x value and see if for every x value, is there ONLY one y-value. So in your example, it is a function because every x value has only one y value. Let’s say you had (1,3) and (1,5). That would not be a function because the x value of 1 has TWO y values (3 and 5), therefore it is not a function.

That’s how you can easily spot if something is a function by just looking at a handful of ordered pairs. I hope this makes sense.

b - D = 576 feet from the hive to the flowerbed.

What is the value of the square root of 72 to the nearest tenth?

Answers

Answer:

8.5

Step-by-step explanation:

Because I used a calculator

The square root of 72 is 8.48528137424 ...

The hundredths digit (8) rounds up.

So the square root of 72 rounded to the nearest tenth is 8.5.

Now you can multiply this to see if the product is near 72.

8.5 times 8.5 is 72.25.

Is x = 6 a solution to the equation 5(x – 3) = x + 13? Follow the steps to find out. 1. Rewrite the equation 5(x – 3) = x + 13 with 6 substituted for x. Write a question mark over the equal sign to show that you're testing to see if the equation is true. 2. Simplify both sides. Show your work. 3. Is x = 6 a solution to the equation? Why or why not? 4. Find a value of x that is a solution to 5(x – 3) = x + 13. Describe how you found the solution.

The length of the edging will be equal to the circumference of the circular flower garden.

Here, the diameter of the circular garden is [tex]d=12\ \text{foot}[/tex]

Circumference of a circle is given by
