Answers

Answer:

$0.65

Step-by-step explanation:

Jose bought 750 bags for $375.00

 

 

 

Each bag cost $375/750= $0.50  

 

He  intends to sells them for $0.15 more

 

 

He should charge : $0.5 +$0.15=$0.65

Answer:

cost of 750 bags =$375

cost of 1 bag = 375/75=5

he want 0.15 more for each

so he had to sell each bag in 5 +0.15=5.15

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that 18 is 2/3 rd of the number. The value of the unknown number will be calculated as,

2 / 3 x = 18

x = ( 18 x 3 ) / 2

x = 9 x 3

x = 27

Therefore, the unknown number will be 27.

Step-by-step explanation:

Step 1:

- 12x + 18 - 10x - 5 = - 31

Step 2:

- 22x + 18 - 5 = -31

Step 3:

- 22x + 13 = - 31

Step 4:

Answer:

Your answer is x = 2

Step-by-step explanation: [tex]-12x + 18-10x-5 = -31[/tex]

subtract 18 - 5 = 13 and add -12x+(-10x)= -22x

[tex]-22x+13=-31[/tex] subtract 13 on both sides

[tex]-22x+13(-13)=-31(-13)[/tex]  cross out +13(-13) and -31-13= -44

[tex]-22x=-44[/tex] divide -22 on both sides

what is a palindrome,armstrong,mersenne numbers?

Answers

Answer:

A numeric palindrome is a number that remains the same when its digits are reversed.

An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.

A Mersenne prime is a prime number that is one less than a power of two.

Step-by-step explanation:

An example of a palindromic number is 16461.

371 is an Armstrong number since 3^3 + 7^3 + 1^3 = 371.

A Mersenne is a prime number of the form Mₙ = 2ⁿ − 1 for some integer n.

A spinner with 8 equally sized slices has 2 yellow slices, 3 blue slices, and 3 red slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow or blue slice?

Answers

I believe the answer is 1/3 because 1 represents the spin and 3 for your chances to land on blue

The probability that the dial stops on a yellow or blue slice will be 5/8.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

A spinner with 8 equally sized slices.

It has 2 yellow slices, 3 blue slices, and 3 red slices.

Now,

Since, The dial is spun and stops on a slice at random.

Here, Number of yellow and blue slice = 2 + 3

                                                             = 5

And, Total number of slices = 8

So, The probability that the dial stops on a yellow or blue slice = 5 / 8

Answers

Answer:

13

Step-by-step explanation:

time=distance÷speed

650÷50=13

The time taken by the gorilla to hit the ground will be 13 seconds.

What is speed?

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that Thomas the giant gorilla climbed to the top of the building 650 feet tall. He broke loose a statue and threw it down with an initial velocity of 50 feet per second.

The time taken by the gorilla will be calculated by the formula of speed below,

Speed = Distance / Time

Time = Distance / Speed
Time = 650 / 50

Time = 13 seconds

W contains the best franchises of 2015 according to Entrepreneur. If W= {Hampton Hotels, Anytime Fitness, Subway, Jack in the Box, Supercuts, Jimmy Johns, Servpro, Denny's, Pizza Hut, 7-Eleven}, how many proper subsets does W contain?

Answers

Answer:

Proper Subsets = 1023

Step-by-step explanation:

Given[tex]W= \{Hampton\ Hotels, Anytime\ Fitness, Subway, Jack\ in\ the\ Box, Supercuts, \\Jimmy\ Johns, Servpro, Denny's, Pizza\ Hut, 7-Eleven\}[/tex]

Required

Determine the proper subsets

Proper Subset (P) is calculated using;

Where

[tex]n = number\ of\ elements[/tex]

In this case;

[tex]n = 10[/tex]

So:

[tex]P = 2^n - 1[/tex]

[tex]P = 2^{10} - 1[/tex]

Angle XYZ = 2X ° and angle PQR = (8X -20)° if angle XYZ and angle PQR or supplementary find the measure of each angle angle XYZ = ?

Answers

Answer:

angle XYZ = 40°

Step-by-step explanation:

given,

angle XYZ = 2x°

angle PQR = (8x-20)°

now,

2x+8x-20° = 180°{being supplementary angle}

or, 10x - 20° = 180°

or, 10x = 180°+20°

or, x = 200°/10

or, x = 20°

again,

angle XYZ = 2x°

= 2× 20°

= 40°
