find the original price of a pair of shoes if the sale price is $40 after a 60% discount

Answers

Answer:

Thus, the original price of the pair of shoes was $100.

Step-by-step explanation:

Percentages

After a 60% discount, the sale price is now valued at 100-60=40% of its original price.

If the sale price is $40, then the original price is calculated as

$40 / 40 * 100 = $100

Thus, the original price of the pair of shoes was $100.

Verify applying 60% discount:

$100 - 60*$100/100 =  $40

One card is drawn at random from a deck of 52 cards. The first card is not replaced, and a second card is drawn. (Enter your probabilities as fractions.)

Required:
a. Find the probability that both cards are clubs.
b. Find the probability that the first card is a spade and the second is a club.

Answers

Answer:

We have a 52 card deck:

a. Find the probability that both cards are clubs.

The probability of drawing a club will be equal to the quotient between the number of clubs in the deck divided by the total number of cards in the deck.

We initially have 13 clubs and 52 cards, then the probability of drawing a club in the first draw is:

p1 = 13/52.

Now the probability of drawing a club in the second draw will be:

p2 = 12/51

Where each number is decreased by one because we already drew a card, and that card was a club.

Then the probability of both events happening will be equal to the product of the individual probabilities:

P = p1*p2 = (13/52)*( 12/51) = 0.059

b. Find the probability that the first card is a spade and the second is a club.

Same as before, the probability of first drawing a spade is:

p1 = 13/52

And the probability of drawing a club in the second draw will be:

p2 = 13/51

This case differs from the prior one because for the second draw we have 13 clubs in the deck, and as we already drew one card (that was not a club) the total number of cards in the deck is 51.

Now the joint probability will be:

P = p1*p2 = (13/52)*(13/51) = 0.064

First you multiply 22 times 1/3 which will give you 22 1/3 then you make it into a mixed number by multiplying the bottom number of the fraction with the whole number and then adding it with the top number of the fraction in this case is (22*3)+1 then you multiply fractions normally by multiplying the top and bottom numbers with each other In this case would be -4*67 and 3*7 and the you get your answer (simplify if necessary)

If |14 -2x = 20, x could equal which of the following?

Answers

Answer:

x would equal -3

Step-by-step explanation:

want to get rid of 14 from each side so 14 - 14 would get rid of that 20 - 14 = 6 now you still have a negative 2x

-2x / -2x gives you X to be alone now divide 6 with -2 which gives you -3

The value of x is -3.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

14 -2x = 20

Now, solving for x

Subtract 14 both side

14- 2x - 14= 20- 14

-2x = 6

Divide by (-2)

-2x/(-2)= 6/ (-2)

x= -3

Hence, the value of x is -3.

If I run 2 1/2 miles in 19 1/5 minutes what is my average time per mile

Answers

Answer:

7:41

Step-by-step explanation:

19 1/5 as a decimal is 19.2, and the mileage would be 2.5. to find the time per mile, you divide the finish time by the number of miles you ran:

  19.2 / 2.5 = 7.68

now you're prolly wondering, "why isn't the answer 7.68?" that's a good question, and the reason that 7.68 isn't the answer is bc time is all in factions of 60, not 100 like most things, so there are 60 seconds in a minute, instead of 100 seconds in a minute.

so, you have to find out how many seconds are in 0.68 of a minute. to do this, you multiply 60 by 0.68:

  60 x 0.68 = 40.8

so 0.68 of a minute is 40.8 seconds, so your average pace was 7:40.8. i would just round up to 7:41, but your teacher may want exact numbers.

hopefully that helps and isn't too confusing! if you need any other help, let me know! :)

Answers

Answer:

Area of [tex]\triangle[/tex]ACD = 4 [tex]ft^2[/tex]

Area of [tex]\triangle[/tex]ABC = 16 [tex]ft^2[/tex]

Step-by-step explanation:

Given that:

D is a point on AB.

and ABC is a triangle.

AD:DB = 1 : 3

Area of [tex]\triangle[/tex]CDB = 12 [tex]ft^2[/tex]

Kindly refer to the attached image as per the given dimensions and values.

To find:

Area of [tex]\triangle[/tex]ACD and Area of [tex]\triangle[/tex]ABC = ?

Solution:

Formula for area of a triangle = [tex]\frac{1}{2}\times Base \times Height[/tex]

The altitudes of triangles [tex]\triangle[/tex]CDB and [tex]\triangle[/tex]ACD are equal in dimensions.

Therefore the area of triangles [tex]\triangle[/tex]CDB and [tex]\triangle[/tex]ACD will be equal to the ratio of their bases.

Area of [tex]\triangle[/tex]ACD : Area of [tex]\triangle[/tex]CDB = AD: DB = 1 : 3

[tex]\Rightarrow[/tex] Area of [tex]\triangle[/tex]ACD = [tex]\frac{12}{3} = \bold{4 ft^2}[/tex]

Area of [tex]\triangle[/tex]ABC = Area of [tex]\triangle[/tex]ACD + Area of [tex]\triangle[/tex]CDB = 12 + 4 = 16 [tex]ft^2[/tex]

Therefore, the answer is:

Area of [tex]\triangle[/tex]ACD = 4 [tex]ft^2[/tex]

Area of [tex]\triangle[/tex]ABC = 16 [tex]ft^2[/tex]

What is a Matrix?

A matrix is an array of numbers or expressions used in mathematics to solve a system of equations.

The matrix A is

[tex]\begin{pmatrix}1/2 & 1/4\\ 9& -3\end{pmatrix}[/tex]

The matrix Ax is

[tex]\begin{pmatrix}5 & 1/4\\ 0& -3\end{pmatrix}[/tex]

The matrix Ay is

[tex]\begin{pmatrix}1/2 & 5\\ 9& 0\end{pmatrix}[/tex]

The determinant for all the matrices is

|A| = -15/4

|Ax| = -15

|Ay| = -45

The value of x is (|Ax|) /(|A|) = -15 / (-15/4) = 4

The value of y is ( |Ay|)/(|A|) = -45 /(-15/4) = 12

Therefore, the value of x and y is 4,12., the correct option is C.
