Evans plan is to put half his money un his savings account,spend 1 over 5 of his money on bubke gum,and buy cómic books with the money he has left.What portion of money will he spend con cómic books.
Answers
we have 1/2 and 1/5, the lowest common denominator is /10
when put over 10 we have 5/10 and 2/10
now add the two together
5/10 + 2/10 = 7/10, that is how much money has been claimed by the savings account and the bubble gum total.
now subtract what has been claimed from the whole
10/10 - 7/10 = 3/10, this is the portion remaining to be spent on comic books

Jacob makes the following statement: "I have a 60% chance of being selected as the captain of the baseball team and a 20% chance of being elected student body president." What is the probability that Jacob will be selected as the captain of the baseball team and will be elected student body president?
Answers
Answer: Our required probability is 12%.
Step-by-step explanation:
Since we have given that
Probability of being selected as the captain of the baseball team= P(A) = 60%
Probability of being selected as elected student body president = P(B) = 20%
We need to find the probability of being selected as the captain of the baseball team and will be elected student body president.
Since both the events A and B are independent events.
So, it becomes,
[tex]P(A\cap B)=P(A)\times P(B)=0.6\times 0.2=0.12\times 100\%=12\%[/tex]
Hence, our required probability is 12%.

in January 2011 the rate of VAT increased from 17.5% to 20%
work out the difference in price of a car worth £15000 +VAT due to increase in VAT
Answers
The difference in price of a car is £375 it is due to the rate of VAT increase from 17.5% to 20% and this can be evaluated by the help of unitary method.
Given :
Rate of VAT increased from 17.5% to 20%.
Total price of a car = £15000 + VAT.
In this problem unitary method can be used to determine the difference in price of a car which is due to the increased rate of VAT.
The price of VAT when its' rate is 17.5% can be:
[tex]= \dfrac{15000}{100} \times 17.5[/tex]
= £ 2625
Therefore, the total price of car when VAT is 17.5% is £17625.
The price of VAT when its' rate is 20% can be:
[tex]= \dfrac{15000}{100} \times 20[/tex]
= £ 3000
Therefore, the total price of car when VAT is 20% is £18000.
So, the difference in price of car = 18000 - 17625 = £375.

A. 3x2 – 2x – 6
B. 2x – 3x2 – 2
C. 3x2 – 2x + 2
D. x2 + 2
Answers
The correct answer is:A. 3x^2 −2x−6
To find (f−g)(x), you subtract g(x) from f(x).
So,(f−g)(x)=f(x)−g(x)
Given that
f(x)=3x^2 −2 and g(x)=2x+4, let's substitute these into the expression:
(f−g)(x)=(3x^2 −2)−(2x+4)
Now, distribute the negative sign:
(f−g)(x)=3x^2 −2−2x−4
Combine like terms:
(f−g)(x)=3x^2 −2x−6
So, the correct answer is:A. 3x^2 −2x−6
max donated 16 collars to the dog shelter . Mia donated some leashes. hiw many items does Mia need to donate that would require you to regroup to find the total number of items donated?
Answers
Answer:
4.
Step-by-step explanation:
To find the total, we would be adding together Max's donated items and Mia's donated items.
"Regrouping" is just another way of stating that we have to carry in the addition.
If we add 16+1, there is no carrying or regrouping.
If we add 16+2, there is no carrying or regrouping.
If we add 16+3, there is no carrying or regrouping.
If we add 16+4, we must carry (regroup). This is because 6+4 = 10, so we carry 1 to the tens place. This is the first time we would regroup this number.
To regroup is another term used for "carry" in arithmetic operations
The least number of items Mia would add, that would require regroup is 4
From the question, we have:
[tex]Max= 16[/tex]
When 1, 2 or 3 are added to 16, there is no "carry" operation.
Because, they are all straight addition operations
[tex]16 + 1 = 17[/tex]
[tex]16 + 2= 18[/tex]
[tex]16 + 3 = 19[/tex]
However, when 4 is added to 16, there is a need to regroup.
The addition is illustrated as follows:
[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\&&\end{array}\right][/tex]
Add 6 and 4;
The result is 10.
So, we write down 0, and "carry" 1
[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\&0&\end{array}\right][/tex]
Next, add 1 (the one beside 6) to the 1 we carried in the previous addition
The result is 2
[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\2&0&\end{array}\right][/tex]
The process of "carrying" is what is referred to as regroup
So, the least number of items Mia would add, that would require regroup is 4

Tony's calculator correctly shows 3.4 x 0.5=1.7. Explain why the number of decimal places in the product is not the same as the number of decimal places in the two factors.
Answers
Answer:
The given product is
[tex]3.4 \times 0.5 = 1.7[/tex]
This results was showed by the calculator, which doesn't shows the two decimal numbers that it should have.
The reason why the calculator only shows one decimal number, it's because the second decimal number is zero, and it would be the same if we express [tex]1.7[/tex] or [tex]1.70[/tex], that zero doesn't change the value that the number represents.
However, if we solve without calculator, we would have [tex]1.70[/tex], because the multiplication rule states that we should add to the result as many decimal number have both factor of the multiplication, which in this case they have two.
When multiplying or dividing decimals, the number of decimal places in the product or quotient may not be the same as the factors or dividend and divisor. The product or quotient should have the same number of decimal places as the factor/dividend or divisor with the fewest decimal places.
Explanation:When multiplying or dividing decimal numbers, the number of decimal places in the product or quotient may not be the same as the number of decimal places in the factors or dividend and divisor. This happens because the calculator does not consider significant figures and simply performs the operation.
To determine the number of decimal places in the product or quotient, look at the decimal places in the factors or dividend and divisor. The product or quotient should have the same number of decimal places as the factor/dividend or divisor with the fewest decimal places.
In Tony's example, 3.4 x 0.5 = 1.7, the factor with the fewest decimal places is 0.5 with one decimal place. Therefore, the product should also have one decimal place.

If we're dealing with a right triangle, then the sum of the squares of the 2 shorter sides of the triangle is equal to the square of the hypotenuse:
a^2 + b^2 = c^2
In your particular problem, a = x+6, b= x+3, and c = x+9.
Then (x+6)^2 + (x+3)^2 = (x+9)^2
so: x^2 + 12x + 36 + x^2 + 6x + 9 = x^2 + 18x + 81
Cancel x^2 from both sides. Then you have
12x + 36 + x^2 + 6x + 9 = 18x + 81
Now group all the x terms together on the left side:
12x + x^2 + 6x - 18x + 36 + 9 - 81 = 0
Combine all the x terms. Combine all the constants.
x^2 - 36 = 0 Factor this: (x-6)(x+6) = 0
Then x=6 and x=-6. We must check whether one or both of these results is correct before calling it a "solution."
Example: (-6+6)^2 + (-6+3)^2 = (-6+9)^2 True or false?
0 + 9 = 9 True! so x = -6 is a solution.
You MUST also check to determine whether or not 6 is also a solution.
Marisa is walking from her home to her friend Sanjay's home. When she is 12 blocks away from Sanjay's home she looks at her watch. she looks again when she is 8 blocks away from Sanjay's home and finds that 6 minutes have passed?

C. find the slope of the line and describe what it means in the context of the problem
D. write an equation in point slope form for the situation and use it to find the number of minutes It takes to reach Sanjay's home. show your work
Answers
A. For this to be a linear situation, we must assume that Marisa is walking a straight path so that the time needed to cover a distance is constant.
B. The equation of the line is given as:
y = m x + b
where in this case y is the distance, m is the slope or the time it takes for each block, x is the time, and b is the y intercept or the initial position of Marisa
C. The slope m can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (8 – 12) / (6 – 0)
m = -0.67
The negative sign means that the distance between Marisa and Sanjay’s home is decreasing by time. It further means that there is a decrease in 0.67 blocks per minute.
D. y = - 0.67 x + b
The initial point of Marisa is at 12 blocks away from Sanjay’s home, hence b = 12.
Finding for time x when distance is 0 (y = 0):
0 = -0.67 x + 12
x = 17.9 minutes
Hence it takes around 17.9 minutes to reach Sanjay’s home.
Seth made a small rectangular table for his workroom. The sides of the table are 36’ and 18’. If the diagonal of the table measures 43’, is the table square?
Answers
Final answer:
Seth's table is not square because it has different side lengths of 36' and 18'. For a rectangle to be a square, all four sides must be of equal length. Additionally, the side lengths and the diagonal of Seth's table do not satisfy the Pythagorean relation for a square.
Explanation:
To determine whether Seth's table is square or not, we need to recognize that a square is a rectangle with equal sides. Since the table has sides measuring 36' and 18', we can immediately conclude that it is not square because the lengths of the sides are different. In a square, the lengths of all four sides would be equal.
To further illustrate this point, let's consider the diagonal of a square. For a square, the diagonal can be determined using the Pythagorean Theorem, where the diagonal is the square root of twice the side squared, because a square is essentially two identical right-angle triangles put together.
In Seth's table, if we were to apply the Pythagorean Theorem (a² + b² = c²), we would find that the square of one side plus the square of the other should equal the square of the diagonal. By doing the calculation:
36'² + 18'² = 1296' + 324' = 1620',
which does not equal the square of the diagonal given, which is 43'² = 1849'. This further confirms that the table cannot be square since the sides and the diagonal do not satisfy the Pythagorean relation for a square.
