Solved the inequality correctly and graphed their solution correctly.

Answers

Answer:

solved the solution incorrectly and graphic their solution correctly.

Step-by-step explanation:

this is because if 4x + 1<= -4

the next step will be to subtract 1 from both sides.

BUT if their solution is x<= 2, they objectively graphed it correctly

Step-by-step explanation:

Celia wants to buy three shirts, which were originally priced $56 each. The store will discount the
price of the third shirt and then apply a 7% tax to the total cost of all three shirts.

Including the tax.
what will be the mean cost of each shirt? (Round your answer to the nearest cent).

Including the tax, the mean cost of each shirt is $___?

Answers

Answer:

$49.93

Step-by-step explanation:

Original cost = $56

Cost of 3 shirts:

3*$56 = $168

Cost of 3 shirts with discount:

168 - 1/2*56 =

168 - 28 =

$140

Add tax:

$140*1.07 = $149.8

Mean cost of each shirt:

$149.8/3 = $49.93

The sophmore class at south high school raised $800 from ticket sales for the dance. Tickets sold for $1.50 pre - sale, and $2.00 at the door. If a total of 475 tickets were sold how many tickets were sold at the door?

Answers

Answer:

So they sold 300 tickets in advance and 175 tickets at the door.

Step-by-step explanation:

Answer:

175 tickets were sold at the door.

Step-by-step explanation:

Let x = number of pre-sale tickets.

Let y = number of tickets sold at the door.

Equation for total number of tickets:

x + y = 475

Equation of total price of tickets:

1.5x + 2y = 800

System of equations:

x + y = 475

1.5x + 2y = 800

Solve the first equation for x:

x = 475 - y

Substitute into second equation.

1.5(475 - y) + 2y = 800

712.5 - 1.5y + 2y = 800

0.5y = 87.5

y = 175

Answer: 175 tickets were sold at the door.

Pls answer all four. Please and thank you & Thank you.

Answer:

1/4

Step-by-step explanation:

First - Convert all fraction with the Greatest Common Factor of 12

12 1/2 = 150/12

4 1/4 = 51/12

2 2/3 = 96/12

Second - Subtract the patio wood and the total

150/12 - 51/12 - 96/12 = 3/12

Third - Simplify 3/12 to 1/4

1/4 of the total wood is left to build the frame of the birdhouse.

The answer is 1/4 hope this helps

Using a tape measure or ruler, measure the length (in inches) of a persons left foot and then measure the length (in inches) of that same persons forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person.(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)To measure the forearm, measure inside the arm, between the wrist and the elbow.Part 2Organize your data and find the rate of change.Create a table of the measurements for your data.

Use your prior knowledge and the book to fill in the following blanks, then go in the hall andperform the lab.A wave is a disturbance that moves through (propagates) through empty space or through a_____________. There are two types of waves. A _____________________ wave requiresmatter to travel. List some examples of this type:A _____________________ wave does not require a medium. Examples include:In order to start and transmit a mechanical wave, a source of _____________ and an_______________ medium are required. A single disturbance is referred to as a_______________, and a series of disturbances is a wave __________.The questions in bold are those you should observe directly. Others will be answered using the book.A. TYPES OF MECHANICAL WAVES: In the hall, stretch the slinky on the floor until it isstretched (but still loose). Practice sending single pulses down the slinky by popping your wristfrom the center to the side and back to the center. Then send a continuous wave train along asyour partner holds the other end still. A piece of ribbon should be tied to one coil. Watch themotion of this ribbon (representing a particle) as the wave travels through the spring.In this type of wave, the particles move (perpendicular, parallel)to the direction the wave travels. This type of wave is called a __________________ wave.Its pulses are called ________________ and ________________.Now send a pulse by quickly pushing the spring forward and pullingit back, as shown. This type of wave is called _______________. Watch the motion of the ribbon.In this type, the particles move _____________ to the direction the wave travels. Its pulsesare called _____________ and _____________. Label each.Note that all waves transfer _____________ without transferring _______________. Inmechanical waves, particles of the medium vibrate back and forth in simple harmonic motion whilethe disturbance (or _____________) moves from one place to another.B. WAVE SPEEDSend a large pulse, followed by a small one. Does one pulse catch up to the other? ______(Hint: The person who sends these waves should watch how the waves look when they return. Makesure that both pulses are large enough initially to make it back to the sender!) The size of thepulse is called the __________________ of the wave. Did the size affect the speed? ______Generate a single transverse pulse in the slinky, keeping the stretch constant. Using a stopwatch,time the journey of the pulse from one end to the other and back again. Take the average ofseveral trials. _________Without changing your positions on the floor (therefore keeping the _____________ the pulsetravels the same), pull the slinky tighter using only about 3/4 of the coils. This makes a completelydifferent medium through which the pulse will travel.
