### Which calculation should be completed first to solve this story problem? Allister bought some sheet music. He bought 6 songs for $0.99 each and 1 book for$16.99. He paid $1.38 in sales tax. He gave the cashier$50. How much change should Allister get? A. total cost of all the purchases B. total cost of 6 songs C. sum of the cost of 1 song, the book, and the tax D. the change

A. total cost of all the purchases

You can't calculate the sales tax on the sheet music or the change for $50 he would have received (which requires subtracting the total cost from$50) until you know how much the sheet music cost total.

The B) and C) options aren't  relevant to the problem. You're trying to find the amount of change he gets after paying the total cost for all the sheet music + the tax on that.

### For two weeks, Mark recorded the color of the traffic light at the intersection of Acorn Street and Fifth Avenue as his bus approached the intersection. He created this frequency table. How many times was the traffic light red? Red: ? Green: 6 Yellow: 2 Total: 15

Hey there!

If the total amount of times Mark recorded the color of the traffic light is 15, then the number of red lights he recorded would be 15 minus the amount of green and yellow lights.

15 – 6 – 2 = 7

There was a total of 7 red lights recorded by Mark.

Hope this helped you out! :-)

### A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, the angle of depression to the boat is 17°44'. When the boat stops, the angle of depression is 48°13' . The lighthouse is 200 feet tall. How far did the boat travel from when it was first noticed until it stopped? Round your answer to the hundredths place.

Distance covered by the boat was 446.27 feet

Step-by-step explanation:

A boat which is at the point C approaching the light house.

At point C angle of depression to the boat was 17°44' and when boat stops at point B angle of depression was 48°13'.

Length of the tower is 200 feet then distance DC traveled by the boat.

Since at point B angle of depression was 17°44' so we will convert the angle in degrees.

Angle of depression = ∠ACB = 17°44' =

From ΔABC

tan 17.73° =

Now in ΔABD

∠ADB = 48°13' = 48° + = 48.217°

Now

Therefore distance DC = BC - BD

DC = 625 - 178.73 = 446.27 feet

So the answer is 446.27 feet was distance covered by the boat.

scientific notation is defined as

if we have
2.3
in sciefitific notation, 0 places must be moved so it would be written as
2.3 x 10⁰
so yes, 0 can be an exponent, tho it would not be helpful and would just be more work

### A person is waiting in line to get into a sporting event. The data in the table represents the relative position, in feet, of the person to the entry gate over time in seconds.What does the slope of the linear equation that models the data represent?The person is moving closer to the entry gate at a rate of 1.5 feet per second.The person’s speed is increasing as the person approaches the entry gate.The person’s speed is decreasing as the person approaches the entry gate.The person is moving farther away from the entry gate at a rate of 1.5 feet per second.

Each time x goes up by 1, y goes down by 1.5

So,

Slope = rise/run = (change in y)/(change in x) = -1.5/1 = -1.5

indicating that the distance to the gate y is decreasing at a rate of -1.5 ft/second. Put another way, the person is moving 1.5 ft per second closer to the entry gate.

This is why the answer is choice A

### An acorn falls from the branch of the tree to the ground 25 feet below. The distance, s, that the acorn is from the ground as it falls is represented by the equation S(t)=16ft+25 where t is the number of seconds. For which interval of time is the acron moving through the air?

The equation can be rewritten as 45t=16+25 (since 45 is the distance the acorn feel from the tree or s). You would then add 16 and 25 ft together to get 41 and change the equation to 45t=41. Divide 45 from both sides to get approximately 0.9 seconds as your answer.

### If a spacecraft was parked on Venus and needed to make a flight to Jupiter, how far would it need to travel? (Assume both planets are aligned with the sun and are on the same side of the sun.) Show your work and provide your answer in scientific notation.

In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000

so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n

so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so

365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km

those are the distances in scientific notation

### Construct a two-way frequency table for the data. Include row and column totals. Hint: Let column categories be labeled by after school activity. Every student at Georgia Southern Middle School participates in exactly one after school activity. The school activities coordinator recorded data on after extracurricular activity and gender for all 254 seventh-grade students at the school. The counselor’s findings for the 254 seventh-grade students are the following: Of the 80 students enrolled in music, 42 are male. Of the 21 students enrolled in student government, 9 are female. Of the 65 students enrolled in theatre, 20 are male. Of the 88 students enrolled in sports, 30 are female.

Step-by-step explanation:

We have to construct a two way frequency table for the data.

Every student at Georgia Southern Middle School participate in exactly one after school activity.

1. Out of 80 students enrolled in music, 42 are male.

So female students enrolled i music = 80 - 42 = 38

2. Out of 21 students enrolled in student government, 8 are female.

So number of male students = 21 - 9 = 12

3. Out of 65 students enrolled in theater, 20 are male.

So number of female students = 65 - 20 = 45

4. Out of 88 students enrolled in sports, 30 are female.

So the number of male students = 88 - 30 = 58

Now we will form the frequency table

Activity                           Male         Female       Total

Music                              42                38             80

Student government      12                  9              21

Theater                            20                45             65

Sports                              58                 30             88
