B. identified the variables for the linear situation and identify two points on the line explain the meaning of the points in the in the context of the problem
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

Answer 1

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.

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.

Final answer:

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.

What is the probability that Jacob will be selected as the captain of the baseball team and will be elected student body president?

Answers

since a and b are independent, the probabily of both occuring is their product ab=12%

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]

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

no, because the length and the width aren't the same

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.

In #15 you need to apply the Pythagorean Theorem.

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.

Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $ 2 0 0 $200dollar sign, 200 a month and an additional $ 1 2 $12dollar sign, 12 for each album that he sells. Last month he earned a total of $ 6 4 4 $644dollar sign, 644. Write an equation to determine the number of albums ( a ) (a)left parenthesis, a, right parenthesis Floyd sold last month. Find the number of albums Floyd sold last month.

Answers

y=amount made
x=number of albums sold
y=$200+12x

Want to solve for x
(y-$200)/12=x
y=644
(644-200)/12=x
444/12=x
x=37 albums
Final answer:

To find the number of albums Floyd sold last month, we calculate it using the linear equation $644 = $200 + ($12 \u00d7 a), where $644 is the total earnings, $200 is the base rate, and $12 is the amount earned per album. Floyd sold 37 albums last month.

Explanation:

To determine the number of albums Floyd sold last month, we can set up a linear equation based on the information provided. Floyd is paid a base rate of $200 per month, and he earns an additional $12 for every album sold. The total amount Floyd earned last month was $644.

Let's let a represent the number of albums sold. The equation that represents the total earnings for the month would be:

Total Earnings = Base Rate + (Number of Albums Sold × Price per Album)

Based on what has been given, we can express this as:

$644 = $200 + ($12 × a)

To find the number of albums sold, we subtract the base rate from the total earnings, then divide by the additional amount earned per album:

$644 - $200 = $12 × a

$444 = $12 × a

a = $444 / $12

a = 37

So, Floyd sold 37 albums last month.

suppose that Y and Z are points on the number line if YZ=11 and Y lies on -9 where would Z be located

Answers

Z would be located on 2, since (9+2 =11)

Final answer:

Point Z is located at 2 on the number line, found by adding the distance YZ=11 to the location of Y at -9.

Explanation:

If Y and Z are points on the number line, YZ=11, and Y lies on -9, to find where Z would be located, you simply add the distance between Y and Z to the point Y. Since the distance YZ=11, and Y is at -9 on the number line, you add 11 to -9 to find Z.

Therefore, the location of point Z will be:

-9 + 11 = 2

So, point Z is located at 2 on the number line.

work out the difference in price of a car worth £15000 +VAT due to increase in VAT

Answers

I believe it went from 2625 to 3000, so the difference is £375

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.
