An electronic store orders 5 sets of walkie-talkies for $74.25 each. The store sells each set for $19.90. What is the percent markup, per set, to the nearest percent?

Answer:

A. x<18

B. Given

Step-by-step explanation:

Citizens under the age of 18 are not allowed to vote. This means that 18 is included within the ones that can vote.

let x = the citizens under the age of 18

x < 18 is your inequality (Part A)

For the solution, because it does not include 18, you'll use an open dot (a non-filled in circle) placed on 18, and going to the left (less than).

Answer:

A: 48in2

Step-by-step explanation:

Area of a rectangle = Length x Width

The complete figure is rectangular in shape with:

Length = 11 in

Width = 5 in

Area = 11 x 5

Area = 55 in2

The pink part is triangular in shape with:

height = 4in

Base = 3.5 in

Area of a triangle = 0.5 x base x height

Area of the pink portion = 0.5 x 3.5 x 4

Area of the pink portion = 7 in2

Area of the blue portion = (total Area) - (Area of the pink portion)

Area of the blue portion = 55 in2 - 7 in2

Area of the blue portion = 48 in 2

Hope this help you!

Part A) You would expect her to find numerical answers measured in minutes or hours.

Part B) This is a statistical question because the answers should be numerical and you can receive a variety of answers.

She come up with numerical answers in minutes or hours, and this is a statistical question.

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have:

Minnie is doing a survey to find the time her classmates spend playing musical instruments.

You'd think she'd come up with numerical answers in minutes or hours.

Because the answers should be numerical, and you can get a variety of responses, this is a statistical question.

Thus, she come up with numerical answers in minutes or hours, and this is a statistical question.

Answer:

1. Mixture A

2. y=10

so,x= 4 on solving equations

so 10 would consume 4 spoon in mix B

while 10 would consume 8 spoon in mix A

You apparently need to find the greatest common divisor of (418, 456, 494). You can start by looking at the differences between these numbers. They are

.. 456 -418 = 38

.. 494 -456 = 38

So, if 38 divides these numbers evenly, that is the number of seats in each car. (It does).

train 1 had 418/38 = 11 cars

train 2 had 456/38 = 12 cars

train 3 had 494/38 = 13 cars

_____

The number of seats in each car could be a sub-multiple of 38, say 19. In that case, the number of cars in each train would be twice the number shown above. It is slightly unusual for a train car to have an odd number of seats, but is not unheard of.

The surface area of the rectangular prism with a length of 7.5 in, a width of 5 in, and a height of 6.5 in is 237.5 square inches.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.

A rectangular prism and its dimensions are shown in the diagram.

Then the surface area of the rectangular prism will be  

Surface area = 2 (LW + WH + HL)

We have

L = 7.5 in

W = 5 in

H = 6.5

Then the surface area will be

Surface area = 2 (7.5 × 5 + 5 × 6.5 + 6.5 × 7.5)

Surface area = 2 (37.5 + 32.5 + 48.75)

Surface area = 2 (118.75)

Surface area = 237.5

Step-by-step explanation:

because each week she buys five so you multiply 5 by however many weeks.

Answer:

5y

Step-by-step explanation:

The reason it is 5y is because for every week, Diana buys 5 sodas which means you would have to multiply. For example, if you wanted to find how many sodas Diana drank in 7 weeks you would multiply 5(7) to get 35 sodas in 7 weeks.

Answer:

Step-by-step explanation:

The total number of ways a fair coin can land is 2^6 which is 64 times

The probability of any one of the 6 is 1/64 = 0.015625

The explanation is that there are two ways a coin can land. And each way is independent of the way it landed before. If you consistently get any other answer, then the coin is not a fair one.

The result is 2 * 2 * 2 * 2 * 2 *2 = 64

Answer:

1/64

Step-by-step explanation:

The probability of getting an H is 1/2, the same of getting a T.

The tosses are all independent.  That is, P(H) = P(T) = 1/2, and one toss does not affect the next one in any way.

The desired probability is (1/2)^6 = 1/64.  The exponent 6 is used because 6 tosses occur.
