The math teachers at Newport High School had never golfed before. They set up a friendly competition to see who would have the best round on a full course. The teachers practiced on a driving range the week before they played.

Answer:

Option B

Step-by-step explanation:

In order to find the answer to this question you need to use KCF and solve. Remember that negative times a positive equals a negative.

[tex]-\frac{3}{4} \div\frac{2}{8}[/tex]

Use KCF

[tex]-\frac{3}{4} \times\frac{8}{2}[/tex]

Multiply:

[tex]3 \times 8 =24[/tex]

[tex]4\times2=8[/tex]

Remember that negative times a positive equals a negative:

[tex]-\frac{24}{8}[/tex]

Simplify:

[tex]24\div8=3[/tex]

[tex]8\div8=1[/tex]

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

[tex]=-3[/tex]

Hope this helps.

Answer:

If x =2, then 3x^2 equals 12 :D

Step-by-step explanation:

The solution is 12.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

5-x= 3

i.e. x=2

so, we get,

3x^2

=3*x*x

=12

Hence, the solution is 12.

Answer:

Angad=6

Malachay=3×6=18

Jim=6

Step-by-step explanation:

Angad,malachy and Jim share =£30 ratio =1:3:1

Let the part of the Angad=X

=3x

=X

So X+3x+X=30

5x=30

X=30/5

X=6

So part of Angad=6

Malachay=3×6=18

Jim=6

Step-by-step explanation:

A:M:J

1:3:1

let total amt be 5x

5x = 30

x = 6

thus, A get 6dollars , M get 18 and J 6

Step-by-step explanation:

Answer:

The correct option is;

The situation shows correlation without causation

Step-by-step explanation:

The given data are;

Weight y     [tex]{}[/tex]            Miles Per Gallon

42     [tex]{}[/tex]                           18

36     [tex]{}[/tex]                           12

30     [tex]{}[/tex]                            6

.     [tex]{}[/tex]                                x

24     [tex]{}[/tex]                            0

The first difference of the data = 42 - 36 = 36  - 30 = 30 - 24 = 6

18 - 12 = 12 - 6 = 6 - 0 = 6

The first difference of the data is constant and equal to 6

Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;

The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;

(42 - 24)/(18 - 0) = 1

Therefore, the points of the data fit into the straight line and the data of the situation shows correlation

In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.

Answer:

The situation shows correlation with causation.

Step-by-step explanation:

A correlation between two variables is a measure of the strength of the association between them.

It can be seen from the scatter plot that as the weight of the car increases, the miles per gallon decreases.

Causation between variables indicates that one of the variables causes the other variable to occur. Causation between variables always implies correlation.

The weight of the car affects the miles per gallon because cars that weigh more require more power to move. Hence, heavier cars get lower miles per gallon of fuel.

Therefore, the situation shows correlation with causation.

Answer:

-4 just kidding it is 3

Step-by-step explanation:

Answer:

4 (2 + 9)

Step-by-step explanation:

  Given expression:

              8 + 36

The greatest common factor is the highest number that divides a number:

8 and 36 ;

  Factors of 8 : 1,2,4, 8

                  36 : 1, 2, 3, 4, 9, 18, 36

The highest common factor is 4;

  8 + 36  = 4 (2 + 9)

Given:

Rita covered 1 mile in 15 minutes.

She covered 3 miles in 30 minutes.

To find:

The rate at which she is riding.

Solution:

Let y be the number of miles covered in x minutes.

Rita covered 1 mile in 15 minutes. So, the point is (15,1).

She covered 3 miles in 30 minutes. So, the point is (30,3).

Slope of the line:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-1}{30-15}[/tex]

[tex]m=\dfrac{2}{15}[/tex]

Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Answer:

it will take sierra about 44.4 weeks too run a marathon

Step-by-step explanation:

The expression to represent the given situation is 0.5w+4.

Given that, Sierra wants to train for a marathon. Right now she can run 4 miles.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Let the number of weeks be w.

Now, expression is 1/2 w + 4

= 0.5w + 4

Therefore, the expression to represent the given situation is 0.5w+4.
