A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false. The jacket is now 40% off its original price. True or false The jacket now costs $48.00. True or false The jacket is now 72% of its original price. True or false The jacket now costs $43.20. True or false

Answers

Answer:

Step-by-step explanation:

Step one:

given

original price= $60

discount =20% of 60

discount = 20/100*60

discount = 0.2*60

discount = $12

selling price= 60-12= $48

Added price= 10% off $48

Added price= 10/100 *48

Added price= 0.1 *48

Added price= $4.8

new price= 4.8-48=$43.2

the new price of the jacket is $43.2

1. The jacket is now 40% off its original price

40/100*60=$24-----False

2. The jacket now costs $48.00-----False

3.  The jacket is now 72% of its original price= 72/100*60=$43.2----True

4. The jacket now costs $43.20------True

Sumiko and Jandella ran the bleachers together today at Poly High School. Sumiko runs these same bleachers every 6 days and Jandella runs them every 16 days.

Answers

Answer:

The soonest they will see each other again is in 48 days

Step-by-step explanation:

Here is the complete question:

Sumiko and Jandella ran the bleachers together today at Poly High School. Sumiko runs these same bleachers every 6 days and Jandella runs them every 16 days. The soonest they will see each other again is in days.

Step-by-step explanation:

From the question, Sumiko and Jandella ran the bleachers together today, that is, they saw each other today.

Sumiko runs the bleachers every 6 days while Jandella runs them every 16 days

To determine how soon they will see each other again, we will list the days they will run the bleachers separately.

For Sumiko, she will run the bleachers on the

6th, 12th, 18th, 24th, 30th, 36th, 42nd, 48th, 54th, 60th, etc days after today.

For Jandella, she will run the bleachers on the

16th, 32nd, 48th, 64th, 80th, etc days after today.

From above, they will both run the bleachers on the 48th day after today.

Hence, the soonest they will see each other again is in 48 days.

Answers

Answer:

It would be 11

Step-by-step explanation:

The square's diagonal length is; (E) d = 11√2.

What is a diagonal?

A diagonal is a line segment that connects two vertices (or corners) of a polygon also, connects two non-adjacent vertices of a polygon.

This connects the vertices of a polygon, excluding the figure's edges.

A diagonal can be defined as something with slanted lines or a line connecting one corner to the corner farthest away.

A diagonal is a line that connects the bottom left corner of a square to the top right corner.

So, we need to determine the length of the square's diagonal.

The formula for the diagonal of a square is; d = a2; where 'd' is the diagonal and 'a' is the side of the square.

Now, d = 11√2.

Hence, the square's diagonal length is (E) d = 11√2.

How many cups will you need to find the number of servings for?

Answers

Answer:

24 servings

Step-by-step explanation:

A recipe uses 5 cups of milk to make 10 servings.

We have to carry out some conversions

We have to convert 5 cups to quarts

1 quart = 2 pints

1 pint = 2 cups

Hence, 2 pints = 4 cups

1 quart = 2 cups

1 cup =0.25 quart

5 cups = x quarts

x = 5 × 0.25

x = 1.25 quarts

Hence

1.25 quarts = 10 servings

3 quarts = x

x = 3 × 10/1.25

x = 24 servings

A certain lock has four tumblers, and each tumbler can assume six positions. How many different possibilities are there?

Answers

Answer:

24?

Step-by-step explanation:

4 times 6

Possibilities for one tumbler is 6. So, the number of different possibilities for 4 tumblers is 6⁴ or 1296.

Permutation:

Important information:

A certain lock has four tumblersEach tumbler can assume six positions.

We can use permutation to find the number of possibilities for 1 tumble.

[tex]^6P_1=\dfrac{6!}{(6-1)!}[/tex]

[tex]^6P_1=\dfrac{6!}{5!}[/tex]

[tex]^6P_1=6[/tex]

The number of different possibilities for 4 tumblers is:

6 × 6 × 6 × 6= 1296

Therefore, the number of different possibilities for 4 tumblers is 1296.

Total number of carriers to deliver the newspapers = 18

Each newspaper carrier delivers the same number of newspapers.

To find:

The number of newspapers that each newspaper carrier will deliver ?

Solution:

The solution to this problem lies in the language of the problem itself.

As we are given that every newspaper carrier will deliver the same number of newspapers.

Therefore, we need to divide the total number of newspapers i.e. 4050 in 18 (number of newspaper carriers) equal parts.

So, the answer is:

The art supply store is having a sale. Paint sets are 20% off and everything else is 15% off. Before the discount, a paint set is priced at $43.50, a canvas is $12.75, and paint brushes are $7.50. Mary purchases all three of these items. About how much did Mary spend after the discount, before sales tax? Group of answer choices

Answers

Answer:

Step-by-step explanation:

Step one:

given

paint set= $43.50

20% off 43.50

20/100*43.50

0.2*43.50

=$8.7

43.5-8.7

new price of paint set=$34.8

canvas=$12.75

15% off 12.75

15/100*12.75

0.15*12.75

=1.9125

=12.75-1.9125

new price of canvas=$10.83

paint brushes are $7.50

15% off $7.5

15/100*7.5

0.15*7.5

=1.125

=7.5-1.125

new price of paint brush=$6.38

total =$34.8+$10.83+$6.38= $39.25

Answer:

actually the answer is 52

Step-by-step explanation:

20% x 43.50/100 = 34.8

12.75 x 15% /100 = 10.83

7.50x 15%/100 = 6.37$

Add all of them together and you will get 52$

Easiest way to do it

20% x 43.50/100

12.75 + 7.50 = 20.25

20.25 x 15%/ 100 = 3.03

20.25 - 3.03 = 17.21

Then add all of them together and you will still end up with about 52$

17.21 + 34.8 = 52

The number of grasshoppers is twice the number of crickets. Find the number of
each type of insect that she has

Answers

Arielle has 374 grasshoppers and 187 crickets in all.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let's set

x = number of grasshoppers

y = number of crickets

Arielle has a collection of 561 insects, therefore

x + y = 561            [1]

The number of grasshoppers is twice the number of crickets, so

x = 2y                   [2]

Substituting [2] in [1]:

2y + y = 561

Simplifying

3y = 561

Dividing by 3

y = 561/3

y = 187

From [2]:

x = 374

x = 374

Hence, the number of each type of insect that she has 374 grasshoppers and 187 crickets
