Jules reads that 1 pint is equivalent to 0.473 liters. He asks his teacher how many liters are in a pint . His teachers responds that there about 0.47 liters on a pint. He asks his parents they say they are about 0.5 liters in a pint. Jules says they are both correct . How can that be true explain your answer

Let Maria = X

Andre = 3x ( 3 times as many as Maria)

Jane = 2(3x) = 6x ( 2 times as many as Andre)

All 3 need to equal 840 pounds:

X + 3x + 6X = 840

Combine like terms:

10X = 840

Divide both sides by 10:

X = 840 / 10

X = 84

Maria = X = 84 pounds

Andre = 3x = 3(84) = 252 pounds

Jane = 6x = 6(84) = 504 pounds

504 + 252 + 84 = 840 pounds.

Andre picked 252 pounds.

The answer is B.

Hi,

Jane, Andre, and Maria pick apples. Andre picks 3 times as many pounds as Maria. Jane picks 2 times as many pounds as Andre. The total weight of the apples is 840 pounds. How many pounds of apples does Andre.

Lets say andre picked 252!

Andre - 252

Maria - 252 / 3 = 84

Jane - 252 x 2 = 504

504 + 252 + 84 = 840

Answer:

B) 252 pounds

Hence the approximate values are 2.91 and 2.89

Step-by-step explanation:

The area of a quadrilateral is expressed as

A=L*B

Where L=length

B=breadth or width

I. e assuming it has two of its sides equal

Say given area is

A=L*B=8.4 square feet

Approximately

L= 2.9 feet

Let's us divide the area by L to get B

8.4/2.9= 2.91

The fraction 7/9 converts to the decimal 0.77777778, which is a repeating decimal as the digit '7' repeats infinitely.

To convert the fraction 7/9 to a decimal, divide 7 by 9. So, when you divide 7 by 9, the answer you get is 0.77777778. This decimal does not terminate (come to an end after a specific number of decimal spaces), instead it repeats. Specifically, the digit '7' repeats indefinitely, so we can say its a repeating decimal.

As an example, if you consider 1/2, when you divide 1 by 2 it gives 0.5, which is a decimal that terminates. However, in our case - when we divided 7 by 9 it gave us 0.77777778 which repeats, hence it is a repeating decimal, not a terminating decimal. This is the key difference between repeating and terminating decimals.

Answer:

Step-by-step explanation:

The line in the graph has a rise of 1 for each run of 1, so its slope is 1/1 = 1. The slope (x-coefficient) of the function f(x) = -7x+1 is -7, so that is not the function shown in the graph.

The wording "the range ... is increasing as the domain increases" is a bit unusual. Usually "domain" and "range" refer to intervals or sets of values over which the function is defined. While it is true that extending the interval of definition (domain) of the function will extend the range of values it produces, we suspect this is supposed to suggest that the slope of the line is positive. (As you pick increasing elements from the domain, the function will map those values to increasing elements of the range.)

ANSWER

The correct answer is D

EXPLANATION

The slope of the given line

[tex] =-\frac{1}{3}[/tex]

The line perpendicular to it has slope

[tex]=\frac{-1}{\frac{-1}{3}} =3[/tex]

If the line passes through

[tex](1,27)[/tex]

Then the equation is given by

[tex]y-y_1=m(x-x_1)[/tex]

[tex]\Rightarrow y-27=3(x-1)[/tex]

[tex]\Rightarrow y=3x-3+27[/tex]

[tex]\Rightarrow y=3x+24[/tex]

Equation of the required line which is perpendicular to this line and passes through (1, 27) is y= 3x+24

The equation of the given line is y = -1/3x - 24

Comparing it with the standard form i.e y=mx+c

where 'm' is the slope of the line

and 'c' is the y-intercept of the line

we get 'm=-1/3' and 'c=-24'

Now if two lines are perpendicular the relation between their slopes  'm1' and 'm2' is given as

m1*m2=-1

Thus here m1=-1/3;

(-1/3)*m2=-1

m2=3

Therefore slope of any line perpendicular to  y = -1/3x - 24 would be m2=3

Also given that the line passes through the point  (1, 27)

Thus if a line having slope as 'm' and passing through the point (x1,y1) its equation is given as:

[tex]y-y_{1}=m(x-x_{1})[/tex]

here [tex](x1,y1)=(1,27)[/tex]

and [tex]m=3[/tex]

Thus required equation would be:

y-27 = 3*(x-1)

y-27 = 3x-3

y = 3x-3+27

y= 3x+24

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Event A: You get a red car

and

[tex]P(A)=0.20[/tex]

Similarly,

Event B: You get a convertible

and

[tex]P(B)=0.40[/tex]

So, if A and B are independent , then they must satisfy,

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

So,

[tex]P(A\cap B)=0.4\times 0.2=0.08[/tex]

Hence, Option 'D' is correct, which states that the probability of getting a red convertible is 0.08.

Answer: correct choice is B.

Answer with Explanation:

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.

If a system has no solution, it is said to be inconsistent . Represent parallel lines.

1)   8x + y + 4 = 0  

       y = -8x - 4

If we solve equation 8x + y + 4 = 0  for y, we get

y = -8x -4

So, both equations are same. That means both lines are same. So infinite many solutions.

System is consistent

2) Both line slope are same and parallel to each other.

So,  no solution

System is  inconsistent.

3) Both equation represent the same line. So, infinite many solution.

System is consistent.

4)  Both lines are intersect at a point.

Intersection point is (7,0).

5) Both lines are parallel. So, no solution.

System is inconsistent.

The correlation coefficient of -0.93 suggests a strong negative association between the two variables. Thus, option D is the correct answer.

In the study, it was found that the correlation coefficient between two variables is -0.93, implying a strong relationship between the two variables. But because the coefficient value is negative, it means that there's a strong negative association between the variables. In other words, as one variable increases, the other decreases, and vice versa.

A correlation coefficient ranges from -1 to 1. The strength of the correlation is determined by the absolute value of the coefficient - the closer to 1 (or -1), the stronger the correlation. Positive values indicate a direct relationship, where both variables move in the same direction, while negative values indicate an inverse relationship, where the variables move in opposite directions.

Therefore, in your given options, the right choice is D. There is a strong negative association between the variables.

The points that are contained in the graph of the straight line y = (1/2)x + 3/4 are (0,3/4) and (1/2,1).

An equation describes that both sides of the variables and constants are in different forms but they are equal.

To determine if each given point is contained in the graph of the equation Y = (1/2)x + 3/4 we will put the values of x in the equation and determine the corresponding value of y.

When x = 0, y = (3/4).

When x = (3/4), y = 9/8.

When x = 1/2, y = 1.

So, the points that are contained in the graph Y = (1/2)x + 3/4 are (0,3/4), (1/2,1).

If you borrowed $100, then your monthly payment is $2.44

If you borrowed $200, then your monthly payment is 2*2.44 = 4.88

etc etc

We can set up a proportion

2.44/100 = x/13300

to figure out the monthly payment x. Cross multiply and solve for x

2.44*13300 = 100*x

100x = 2.44*13300

100x = 32452

x = 32452/100

x = 324.52

So the monthly payment is $324.52

An alternative way to get this monthly payment is to apply 2.44% to 13300, which is another way to view the phrase  "monthly payment per $100 is 2.44"

------------------

There are 48 months in 4 years (start with 12 mon = 1 yr, then multiply both sides by 4) so we multiply 48 by the monthly payment to get the result 48*324.52 = 15,576.96. This is the total amount you have to pay back which is the principal plus interest.

Subtract off the principal (amount borrowed) to find the interest or finance charge: 15,576.96 - 13,300 = 2,276.96

Answer: Choice B

The finance charge on $13,300 financed at 7.9 percent for 4 years is $12,975.48.

To calculate the finance charge, we need to first find the total amount financed. We can do this by multiplying $13,300 by the monthly payment per $100, which is $2.44. $13,300 divided by 100 is 133, so we multiply 133 by 2.44 to get $324.52. Now, we can calculate the finance charge by subtracting the total amount financed from the original loan amount. $13,300 minus $324.52 is $12,975.48. Therefore, the finance charge is $12,975.48.
