neil has 3 partially full cans of white paint. They contain 1/3 gallion, 1/5 gallion, and 1/2 gallion of paint. about how much paint does neil have in all

Answers

All the fractions are factors of 30
1/3 X 10, 1/5 X 6, 1/2 X 15.
/\10/30,   /\6/30,    /\15/30
Add all of them together: 31/30
Then you simplify the total: 1+1/30
1 and 1/30 is the answer

Neil has approximately [tex]\( 1 \frac{1}{30} \)[/tex]  gallons of white paint in total.

Let's calculate the total amount of paint step by step:

1. Convert fractions to a common denominator:

[tex]- \( \frac{1}{3} \) gallon = \( \frac{10}{30} \) gallons[/tex]

[tex]- \( \frac{1}{5} \) gallon = \( \frac{6}{30} \) gallons[/tex]

 [tex]- \( \frac{1}{2} \) gallon = \( \frac{15}{30} \) gallons[/tex]

2. Add the amounts of paint in the cans:

 [tex]\( \frac{10}{30} + \frac{6}{30} + \frac{15}{30} = \frac{31}{30} \) gallons[/tex]

3. Simplify the fraction:

 [tex]\( \frac{31}{30} = 1 \frac{1}{30} \) gallons[/tex]

Thus, Neil has approximately [tex]\( 1 \frac{1}{30} \)[/tex]  gallons of white paint in total.

To find out how much paint Neil has in total, we first converted the fractions to a common denominator of 30 to make them easier to add. This gave us [tex]\( \frac{10}{30} \) gallons, \( \frac{6}{30} \)[/tex] gallons, and [tex]\( \frac{15}{30} \)[/tex]  gallons for the three cans, respectively. Adding these fractions together gives[tex]\( \frac{31}{30} \)[/tex] gallons. To simplify, we divide 31 by 30, resulting in[tex]\( 1 \frac{1}{30} \)[/tex] gallons. Thus, Neil has approximately [tex]\( 1 \frac{1}{30} \)[/tex]  gallons of white paint in total.

How do you fact prime numbers

Answers

Prime numbers are numbers that can only be divided by 1 and itself, and no other numbers

for example

1: 1 x 1
2: 2 x 1
7: 7 x 1


Non-examples
9: 9 x 1, 3 x 3
10: 1 x 10, 5 x 2


hope this helps

Final answer:

Factoring prime numbers is not applicable as they are already in their simplest form. In calculations involving exponents with prime numbers, exponent rules can be used to simplify or alter the expression. Understanding these rules empowers you to verify the results and improve your mental math skills.

Explanation:

Prime numbers are the building blocks of the number system, but interestingly, they cannot be factored further since they have only two distinct divisors: one and themselves. Therefore, the concept of factoring prime numbers doesn't apply because they are already in their simplest form. However, when you work with exponents and prime bases, such as in 24 × 10¹², you can manipulate the expression by using exponent rules to simplify or alter its form.

Exponents represent how many instances a base number is multiplied by itself. For example, 10³ equals 10 × 10 × 10, which is 1,000. Similarly, when you see an operation like (53)4, you can multiply the exponents (3 × 4) to understand this as 512, which is 5 multiplied by itself 12 times.

Mastering these concepts avoids confusion and allows for mathematical operations to be performed more readily in your head. Calculators handle these numbers with ease, but understanding the rules lets you confirm the accuracy of your work and can help in developing a life-long skill.

Plot the line for the equation on the graph. y−4=−14(x−5)

Answers

y-4 = -14(x-5)
y-4 = -14x + 70
-14x-y = -4-70
-1(14x+y) = -1(4+70)
-1 gets caancelled on both sides.
so, 14x+y = 74
now to form the points.
Take x as 0
then, 14x0+y = 74
y=74
So, the first point on the graph is (0,74)
Now take y as -10
Then, 14x+(-10) = 74
Now, 14x = 74+10
14x=84
x = 84/14
x = 6
so, the second point is (6,-10)
now connect these two points, (0,74) and (6,-10) and you got the line for the above equation. Similarly, we can get other points like this but would be a part of the same line.

text messages are sent or received each month.

Answers

Part a. is correct. It is 150.

Part b.
First plan: $30 + $0.20 per text
For 50 texts
$30 + 0.20 * 50 = $30 + $10 = $40
For 50 texts, the first plan costs $40

For 50 texts per month, the first plan is better because it costs only $40 instead of $60
Second plan: $60 no matter how many texts

Answer:

a.150

Step-by-step explanation:

We are given that a cell phone provider offers a plan that cots $30 per month plus $0.20 per text message sent or received.

A comparable plan costs $60 per month but offers unlimited text messaging.

a.If number of text messages sent or received  =150

For I plan

Cost of one text message sent or received per month=$0.20

Cost of plan per month=$30

Costs of 150 text messages sent or received=[tex]0.20\times 150=$30[/tex]

Hence, total costs of plan I =$30+$30=$60

But in II plan no charge for text message and cost of plan per month is $60

Hence, the text messages 150 would have to be sent or received in order for the plans to cost the same each month.

b.If number of text messages =50

Then the cost of messages in plan I=[tex]02.0\times 50[/tex]=$10

Cost of plan I =$30

Total cost of plan I=30+10=$40

But in second plan no charge for text messaging and cost per month is $60.

Therefore, plan I is better than second plan.Because the cost of plan I is less than the cost of second plan per month.

Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the mathematical property that she made an error using?

Answers

Answer: The Distributive Property
Aiko didn't seem to realize that rewriting it like that would cause the expression to have a different solution. She should study her math.

Answer:

Given the expression: [tex](4+5i)+(-3+7i)[/tex]

Aiko rewrites the equation by factoring out the [tex]i[/tex] from the expression and this wrote it as,

[tex](-3+7)i+(4+5)i[/tex]

but this is wrong because [tex]i[/tex] is an imaginary number which is with a number 5 and 7.

Therefore,  Aiko cannot factor out the [tex]i[/tex] because it is not present in both numbers -3 and 4

She could rewrote it as

[tex](4-3)+i(5+7)[/tex]

So, she incorrectly used the distributive property by combining the real number and the coefficient of the imaginary part.


A marble is drawn at random from the bag shown below. The bag contains 3 green, 4 yellow, 5 blue, and 8 pink marbles.What is P(not pink)?

Part A: No, he is not correct because when both rounded to the nearest hundredth they equal the same weight. Jayden's fish is 2.12 rounded to the nearest tenth and Leah's fish weighed 2.12. 
 
Part B: 2.12 = 2.120 

I hope this helps you! 

Answer:

Jadyn's claim is wrong.        

Step-by-step explanation:

We are given the following information in the question:

Weight of Jadyn's fish = 2.120

Weight of Leah's fish = 2.12

Jadyn says his fish weighs more because 120 is larger than 12.

Jadyn is incorrect claiming the above fact as:

[tex]2.120 = 2.12\\\\2.120 = \displaystyle\frac{2120}{1000} = \displaystyle\frac{212}{100} = 2.12[/tex]

120 parts out of 1000 are compared to 12 parts of 100 which is equal.

You have 4 dimes, 5 quarters, and 3 pennies in your pocket. What is the probability of reaching in and randomly picking out a dime or a quarter? Express your answer as a fraction in lowest terms.

Answers

You have 12 coins all together. 4 dimes + 5quarters which equals 9 . So 9 out of 12 will be with a dime or quarter

The probability of picking a dime or a quarter is 3/4

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, you have 4 dimes, 5 quarters, and 3 pennies in your pocket.

There are a total of 4 + 5 + 3 = 12 coins in your pocket.

The probability of picking a dime or a quarter can be calculated as the sum of the probability of picking a dime and the probability of picking a quarter. Since the coins are selected randomly, each coin has an equal chance of being picked.

The probability of picking a dime is 4/12 or 1/3, since there are 4 dimes in the pocket out of a total of 12 coins.

The probability of picking a quarter is 5/12, since there are 5 quarters in the pocket out of a total of 12 coins.

Therefore, the probability of picking a dime or a quarter is:

P(dime or quarter) = P(dime) + P(quarter)

P(dime or quarter) = 4/12 + 5/12

P(dime or quarter) = 9/12

P(dime or quarter) = 3/4

So the probability of picking a dime or a quarter is 3/4, or three-fourths.

Answers

Final answer:

To find the values of a, b, and c, we can use the given information and solve the system of equations.

Explanation:

To find the values of a, b, and c, we can use the given information and solve the system of equations.

From the first two statements, we have a/c = 8 and a*c = 2. This allows us to solve for a and c.

Similarly, from the next two statements, we have a/b = -16 and a*b = -1. Using these equations, we can find the values of a and b.

Finally, the last statement gives us b/c = -0.5, and we can use this equation to find the value of c.

Substituting the appropriate values for a, b, and c, we find that a = 1, b = 0.0211, and c = -0.0211.
