if you add the shipping and price together 23.09 dollars and 3 dollar shipping is 26.09 in total

And the 20.29 with 4 dollar shipping is 24.29 in total

Ms. Cathy bought a package of pencils. Out of every 10 pencils, 8 are black. If there are 30 pencils in the pack, what fraction of the pencing in the pack are black?
What percent of the pencils in the pack are black?
What fraction of the pencils in the pack is black?

Answers

Answer:

Fraction: 24/30 Percentage: 80%

Step-by-step explanation:

It might want a simplified version of the fraction, so the answer for that one could be 4/5. I hope this helps :)

The percent of the pencils in the pack are black is,

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Ms. Cathy bought a package of pencils.

And, Out of every 10 pencils, 8 are black. .

Since, There are 30 pencils in the pack,

Hence, The percent of the pencils in the pack are black is,

⇒ 24 / 30 x 100

⇒ 2400 / 30

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 8 / 10 = x / 30

⇒ 240 = 10x

⇒ x = 24

Thus, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

Thus, The percent of the pencils in the pack are black is,

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

Draw a model that shows 3 items being divided equally for 4 people. How much will each person have?

Answers

Answer:

Each person will get 3 pieces

Step-by-step explanation:

First you separate each item in 4 pieces. Then you get 12 pieces. Since 12 divided with 4 is 3, the answer is 3.

We want to draw a model that shows 3 items being divided equally for 4 people, we will see that each person receives 0.75 of an item.

Drawing the model.

Here you just need to create an area that represents 3 elements, then replicate that area but this time with 4 sections, so we can see how much each of the 4 sections takes from the 3 elements.

The model can be seen below. (this is just an example, you should do it with a ruler to have a proper model).

Now to see how much each person haves we just take the quotient:

3/4 = 0.75

Each person receives 0.75 of an item.

How do I graph

y=-1/2x-1

Answers

Answer:

Step-by-step explanation:

Find the x and y intercept, and determine the slope.

X-intercept:

[tex]0=-\frac{1}{2}x-1\\1=-\frac{1}{2}x\\x=-2[/tex]

It crosses the x-axis at x = -2

Y-intercept:

[tex]y=-\frac{1}{2}(0)-1\\y=-1[/tex]

It crosses the y-axis at y = -1

Slope:

y = mx + b

m = slope = -1/2

The graph of the linear equation y = -(1/2)x - 1 is plotted.

Given data:

To graph the equation y = -1/2x - 1, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

So, the slope is -1/2, and the y-intercept is -1.

To plot the graph, follow these steps:

Plot the y-intercept:

Start by plotting the point (0, -1), which represents the y-intercept.

Use the slope to find another point: Since the slope is -1/2, use the rise and run method. From the y-intercept point (0, -1), move down 1 unit (negative 1) and then move to the right 2 units. This gives another point on the line, which is (2, -2).

Hence, the resulting graph should be a straight line sloping downwards from left to right and is plotted below.

A bag contains tiles number 1-10. What is the probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3?​

Answers

Answer:

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

Suppose we have two events, A and B, that are independent. The probability of both happening is given by:

[tex]P(A \cap B) = P(A) \times P(B)[/tex]

In this question:

Event A: Selecting a prime number.

Event B: Selecting a number less than or equal to 3

Probability of selecting a prime number:

Between 1 and 10, we have 4 prime numbers(2,3, 5 and 7), out of 10. So

[tex]P(A) = \frac{4}{10}[/tex]

Probability of selecting a number less than or equal to 3:

Three numbers(1,2,3) out of 10. So

[tex]P(B) = \frac{3}{10}[/tex]

Probability of both:

[tex]P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12[/tex]

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Find the discount.
Original price: $0.75
Discount: ??
Sale price: $0.15

Answers

Answer:

80%

Step-by-step explanation:

0.75 ⇒ 100%

0.15 ⇒ x%

0.75x = 100·(0.15)

0.75x = 15

x = 15/(0.75)

x = 1500/75

x = 20%

100% - (discount) = x%

100% - (discount) = 20%

discount = 100%-20%

discount = 80%

the value of the 5 in the number 40.52 is _____ the value of the 5 in 115.78?​

Answers

It is the place value in the hundreds

The value of each digit in a number is known as the place value. The value of the 5 in the number 40.52 is 10 times the value of the 5 in 115.78.

What is the place value of a digit in a number?

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10

The value of 5 in the given numbers can be written as,

The value of the 5 in the number 40.52 is 0.5.The value of the 5 in the number 115.78 is 5.

Now, we can write the value of the two numbers as,

5 = 0.5 × x

x = 5/0.5

x = 10

Hence, the value of the 5 in the number 40.52 is 10 times the value of the 5 in 115.78.
