The area of a square quilt is 196 square inches. There is a smaller square patch on the quilt with an area of 49 square inches. What is the difference between the overall perimeter of the quilt and the perimeter of the smaller square patch?

Answers

Answer 1

To find your answer you would find the perimeter of the small square which is 28.

You would then find the perimeter of the big square which is 56.

Next, you subtract 56 from 28 and get 28.

So the difference is 28 inches.

Hope this helps!!

Answer 2

First find the length of one side of the quilt and patch. In this case you just need to calculate square roots of 196 and 49.
So the length of one side of the quilt is: √196=14.
The length of one side of the patch is: √49=7.
Last step is to find the difference of perimeter of quilt and the patch: 14×4-7×4=28.
So, here we go, your final answer for this problem should be 28!

Suppose q and r are independent events, and P(Q)= 0.39, P(R)= 0.85. Find P(q and r)

Answers

Answer:
P (q and r) = 0.3315

Explanation:
We are given that:
P (q) = 0.39
P (r) = 0.85

Since the two events are independent, therefore, the formula that we will use to get P (q and r) is as follows:
P (q and r) = P (q) * P (r)

Based on the givens:
P (q and r) = 0.39 * 0.85 = 0.3315

A diner has a breakfast special. A customer can chose scrambled, fried, or poached eggs. The breakfast comes with a side of bacon, sausage, or fruit salad. The customer can choose coffee, tea, or milk. How many different combinations of eggs, side, and drink does a customer have to choose from?

Answers

3x3x3=27

So, there are 27 combinations.

Solution:

Number of ways the customer can choose eggs=3

Number of ways the customer can choose side=3

Number of ways the customer can choose drinks=3

So, total number of combinations for choosing eggs and side and drinks

=3(for eggs) and 3(for sides) and 3(for drinks)

=3 * 3 *3

=27

A customer has 27 combinations of eggs, side, and drink available.

which of the following functions is continuous between x=-3 and x=0? choices on attachment

Answers

When we say that a function is continuous between x = -3 and x = 0 it means that it exists for all values of x in between -3 and 0. Let's take a look at each choice individually:

A: f(x) = (-x + 1)/(x + 2)
Now we don't actually need to know what the graph of this function looks like to see which values it is continuous for, instead we should look at which values of x will make this function undefined - in this case that would be x = -2. The reasoning behind this is that a number divided by 0 would be undefined, so when we search for which value of x would make the denominator of the equation 0, we get:
x + 2 = 0
x = -2
Since x = -2 is within the interval [-3, 0] we cannot say the function is continuous over this interval

B: f(x) = -2/(x + 1)
Using the same method as above we get:
x + 1 = 0
x = -1
x = -1 is again within the interval [-3, 0] and so the function is not continuous within this interval

C: f(x) = 3x/(x - 2)
x - 2 = 0
x = 2
x = 2 is outside the interval of [-3, 0] and so the function is continuous within this interval and C is the correct answer.

Just for the sake of it however we can look at D as well:
D: f(x) = 1/(2x + 1)
2x + 1 = 0
x = -1/2
-1/2 is within [-3, 0] and so D is not continuous over this interval

A college entry exam has 38 questions worth 200 points. The test consists of multiple-choice questions, x, worth 4 points each and essay questions, y, worth 10 points each. Which system of equations can be solved to find the number of multiple-choice questions on the test?

Answers

A system of equations is a set of equations to be solved by elimination or substitution.

There are no options listed in the question to choose from, but the equations should look like the following:

x= # multiple choice questions
y= # essay questions

QUANTITY EQUATION:
x + y= 38

VALUE EQUATION:
4x + 10y= 200

If we solved these two equations by elimination or substitution, we would find the number of multiple choice (x) and the number of essay (y) questions on the test.

ANSWER: x + y= 38; 4x + 10y= 200

Hope this helps! :)

Answer:

Let's use the variables x and y to represent the number of multiple-choice and essay questions on the test, respectively.

The total number of questions is 38, so we can write:

x + y = 38

The total number of points is 200, so we can write:

4x + 10y = 200

This gives us a system of equations:

x + y = 38

4x + 10y = 200

We can solve this system of equations to find the number of multiple-choice questions on the test.

Answers

Answer:
equation is: width = area / length
width = 62.5 yd

Explanation:
For the first rectangle:
We have:
length = 75 yd and width = 60 yd
Therefore:
area = length * width
area = 75 * 60
area = 4500 yd²

For the second rectangle:
We have:
area = area of first rectangle = 4500 yd²
length = 72 yd
area = length * width
width = area / length ............> The required equation
width = 4500 / 72
width = 62.5 yd

Area of the base = area of a rectangle with dimensions 12cm*10cm

Area of the base =12*10 =120 cm²

Height of the pyramid =16cm

34 out of the 150 sold in week 2 were self-help books.

This gives us 68 self-help books out of 300 books sold.

The bookstore owner predicts that 30% of the week's book sales are self-help books. To evaluate this prediction, we need to look at the number of self-help books sold in the samples provided for two separate weeks. In week 1, 34 out of 150 books sold were self-help books, which is 22.67%. In week 2, 30 out of 150 books sold were self-help books, which is 20%. To determine the average percentage of self-help books sold over the two weeks, we average these two percentages: (22.67% + 20%) / 2, which gives us 21.34%.

You can check this result:

These values correspond to those in the table.

Let's just list the coordinats first.
(1,5)
(2,7)
(3,9)
(4,11)

When you see 3 and 9, you sometimes immediately think it is 3x=y, but you have to look at the other coordinates as well. This can be show in option a, 5x=y. This can not be the anser because 3×5=15≠9. We can eliminate that answer. Option B says that you are adding 2, but when you add 2 to 4, it equals 6 and not 11. The same for C, 4 added to 4 equals 8, not 11.
