From a standard deck of cards, what is the probability that you choose a red card and then a 3, assuming you replaced the first card?

Without a clear, consistent pattern in the number of students tutored from Monday to Thursday, it's challenging to accurately predict the number of students for Friday. The pattern initially provided does not follow a simple arithmetic or geometric sequence.

The question asks for the number of students Mr. Simpson will tutor on Friday, given a pattern of students tutored from Monday to Thursday. The pattern is as follows: 4 students on Monday, 9 on Tuesday, 16 on Wednesday, and 21 on Thursday. Looking at the increase in the number of students each day, we see it goes from 4 to 9 (+5), then 9 to 16 (+7), and 16 to 21 (+5). Noticing a pattern or sequence in these increases can be tricky because it seems to alternate in a way that does not hint at a simple arithmetic or geometric progression.

Given this, the exercise might involve a typo or a misunderstanding. Usually, patterns in mathematics follow a clear rule, whether they are linear (constant increase), geometric (constant multiplication), or another form. If a student or teacher encounters such a problem, it is important to go back and check the original problem for any additional information or to clarify the intended pattern.

The multiplication of 12 and 40 can be simplified using place value. Breaking down the 40 to 4 and multiplying gives 48, but remember to adjust back for place value, giving the final answer of 480.

To solve the equation 12x40 using place value, you need to understand that '40' is essentially '4' in the tens place which is equivalent to '4x10'. Multiplying 12 by '4' gives us '48'. Now, remembering that 4 was actually in the tens place, we apply the place value and turn it back into '480'.

This method is nothing more than a simplification of the normal multiplication process: you’re just breaking down the 40 into a easier to handle number (4), doing the multiplication, then adjusting for the fact that the 4 was actually in the tens place, not the ones. So, 12x40 equals 480.

Jupiter is 34.023 AU closer to the Sun than Pluto. This is obtained by subtracting Jupiter's distance from the Sun (5.2 AU) from Pluto's distance from the Sun (39.223 AU).

Distance in space can often be measured in Astronomical Units (AU), which is the average distance from Earth to the Sun. Given that Jupiter is 5.2 AU from the Sun, and Pluto is 39.223 AU from the Sun, you want to find out how much closer to the Sun Jupiter is than Pluto.

To get this, you simply subtract Jupiter's distance from Pluto's distance. That is, 39.223 AU (Pluto's distance) - 5.2 AU (Jupiter's distance).

The outcome of this calculation is 34.023 AU, which means that Jupiter is 34.023 AU closer to the Sun than Pluto.

Final answer:

Jupiter is 34.023 AU closer to the Sun than Pluto, which is calculated by subtracting Jupiter's distance from Pluto's distance.

Explanation:

Distances in space can be measured using the astronomical unit (AU), where 1 AU is approximately 150 million kilometers, the average distance from Earth to the Sun. To find out how much closer Jupiter is to the Sun than Pluto, we subtract the distance from the Sun to Jupiter from the distance from the Sun to Pluto. Given that Jupiter is 5.2 AU from the Sun and Pluto is 39.223 AU from the Sun:

Distance difference = Pluto's distance - Jupiter's distance

= 39.223 AU - 5.2 AU

= 34.023 AU

Therefore, Jupiter is 34.023 AU closer to the Sun than Pluto.

To convert the insect's length from 3 inches to centimeters, multiply by the conversion factor of 2.54 to get 7.62 centimeters, which is the length to the nearest hundredth of a centimeter.

The student asked: An insect is 3 inches long what is the length to the nearest hundredth of a centimeter of the insect? To convert the insect's length from inches to centimeters, we need to use the conversion factor where 1 inch equals 2.54 centimeters.

First, we multiply the insect's length in inches by the conversion factor:

Therefore, the length of the insect is 7.62 centimeters when converted from inches and rounded to the nearest hundredth of a centimeter.

When measuring the length of small items like insects, it is important to choose an appropriate tool and unit for precision. In this case, a ruler that includes both inches and centimeters would be appropriate for measuring an insect of this size. The centimeter, being smaller than the inch and equivalent to 10 millimeters, offers the precision needed for such measurements.

The density of the solid will be equal to 0.2 grams per centimetre cube.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the mass of a solid is 25 g and its volume is 50 cm3. The density of the solid will be calculated as,

Density = Mass / Volume

Density = 25 / 50

Density= 0.2 g/cubic cm

Therefore, the density of the solid will be equal to 0.2 grams per centimetre cube.

Answer:

12.75 squared

Step-by-step explanation:

Remember convert the yards into feet. 2 yards= 6 feet.

6 feet x 4.25 feet= 25.5 feet

remember a=1/2 b x h

after you get 25.5 divided it by 1/2 or 2

then you get 12.75 squared

REMEMBER TO ALWAYS CONVERT!

Final answer:

After dividing the initial total cost of $45.75 by three, each of Juliette and her brothers would pay $15.25. After Juliette's mom contributes $15, the remaining amount of $30.75 is divided by three, resulting in each person paying $10.25.

Explanation:

The question involves dividing a total cost among several people and then re-dividing it after one more person contributes. Initially, Juliette and her two brothers spent $45.75 on flowers. To find out how much each person will initially pay, divide the total cost by the number of people. There are three people, so each person will pay $45.75 ÷ 3 = $15.25.

Next, Juliette's mom decides to chip in $15. After her contribution, the remaining amount to be shared by Juliette and her brothers is $45.75 - $15 = $30.75. Now there are still three people sharing the cost, so each person will pay $30.75 ÷ 3 = $10.25.

Therefore, after Juliette's mom contributes, Juliette and her brothers will each pay $10.25.

To find the combined save percentage, you need to calculate the total number of saves and shots on goal for both goalies, and then divide the total saves by the total shots on goal. The combined save percentage is approximately 0.909.

Your friend's approach of adding the two save percentages and dividing by 2 to find the combined save percentage is incorrect. This is because save percentage is not a simple average of multiple percentages. To find the combined save percentage, you need to calculate the total number of saves and shots on goal for both goalies, and then divide the total saves by the total shots on goal.

5 percent is equivalent to 1/20.

Here we have to write 1/20 as percentage,

Since we know that,

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Now ,

To find the percentage of 1/20 multiply it by 100

⇒(1/20)x10 = 100/20

                  =  5 %

Hence,

1/20 = 5%
