The correct answer is She have left $7.5 after buying the coat and skirt.

Step-by-step explanation

This question is incomplete, the complete question is:

Mary had $60 and spent 0.75 o 3/4 of it on a coat. She then bought a skirt with 50% of the money that she had left. How much money did she have left after buying the coat and skirt?

The answer is $7.50

Explanation:

To know how much money Mary has left after buying the coat we have to multiply $60 by 0.75 as this would help us know the price of the coat.

60 x 0.75 = 45 (price of the coat)

Then we have to subtract 45 from 60 to know how much money she have left after buying the coat.

60 -45 = 15 (Money left)

Then she bought a skirt with 50% of the money that she had left. To know how much money costs the skirt we have to multiply 15 by 0.50. The result of this operation is $7.5, and finally, we have to subtract again $7.5 that she spent on her skirt from $15 and the final result is $7.5

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:

Distance of L from AB = 0.6 in.

m∠ABC = 60°

Step-by-step explanation:

Given:

LB = 1.2 in

LC = 0.6 in

We have to find the distance of point L to AB or length of LD.

From right triangle ΔBCL,

Sin(∠LBC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

                 = [tex]\frac{LC}{LB}[/tex]

                 = [tex]\frac{0.6}{1.2}[/tex]

                 = [tex]\frac{1}{2}[/tex]

m∠LBC = 30° [Since ∠LBC is an acute angle]

Since, ∠LBC ≅ ∠LBA

m∠LBA = 30°

Now from right triangle ΔLDC,

sin(∠LBA) = [tex]\frac{LD}{BL}[/tex]

sin(30)° = [tex]\frac{LD}{1.2}[/tex]

[tex]\frac{1}{2}=\frac{LD}{1.2}[/tex]

LD = 0.6

Therefore, Distance of point L from AB is 0.6 in.

m∠ABC = m∠ABL + m∠LBC

             = 30° + 30°

             = 60°

Answer:

The additive inverse would be -10.5

Henry runs up 10.5 flights of stairs. Then the additive inverse represents running down flights of stairs will be - 10.5.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The reverse number is a number's complementary inverse. When a number is multiplied by its additive inverse, the result is zero.

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:

Option B

Use KCF

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

Multiply:

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

Remember that negative times a positive equals a negative:

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

Simplify:

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)

Answer:

4/5 (or 8/10)

Step-by-step explanation:

the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.  

If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5
