A store sells four-packs of permanent markers in assorted colors for $3.19 per pack. All spiral-bound notebooks, whether wide-ruled or college-ruled, sell for $1.20 each. Cleo buys x packs of markers, y wide-ruled notebooks, and z college-ruled notebooks. The store charges a 6% sales tax on Cleo’s total bill. Which expression represents the amount Cleo must pay after taxes?
A.
3.19x + 1.20y + 1.20z + 1.06
B.
3.19x + 1.20yz + 1.06
C.
1.06(3.19x + 1.20yz)
D.
1.06(3.19x + 1.20y + 1.20z)

Answers

Answer 1

Answer:

D. 1.06(3.19x + 1.20y + 1.20z)

Step-by-step explanation:

Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.

All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.

The cost of the college ruled notebooks can be represented by 1.20z.

In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.

So, the expression will be 1.06(3.19x + 1.20y + 1.20z)

D is the correct answer

Answer 2

Answer:

Solution :-Let cost of marker packs = $3.19xLet the cost of spiral notebook = $1.20 yCost of college ruled book = $1.20 zExpression :-

a driver is below the surface of the water at - 15m. he dives down by 6m, then rises 4m where is he now

Answers

Given:

A driver is below the surface of the water at - 15m. he dives down by 6m, then rises 4m.

To find:

The current location of the driver.

Solution:

In this problem, negative sign is used for downward direction or the distance below the surface of the water.

Initial location = -15 m

Dives down by 6m, it means - 6m, then rises 4m, it means 4 m.

Now, the current location is

[tex]-15 m-6m+4m[/tex]

[tex]=-21m+4m[/tex]

[tex]=-17m[/tex]

Therefore, the correct location of the driver is at -17 m it means her is 17 m below the surface of the water.

On a mountain, the temperature decreases by 18 F for each 5000 foot increase in elevation. At 7000 feet, the temperature is 41 F. What is the temperature at 22,000 feet?

Answers

Answer:

Step-by-step explanation:

To find this answer, use multiples. For every 5000 feet ascended, deduct 18 degrees. For 20,000 feet, which is (4 * 5000), use (4 * -18). In this case, the answer is -72 degrees F, so the integer described would be -72.

The required temperature at 22,000 feet is -13 F.

Given that,
On a mountain, the temperature decreases by 18 F for each 5000-foot increase in elevation. At 7000 feet, the temperature is 41 F, what is the temperature at 22,000 feet is to be determined.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.

Here,
Change in height = 22000 - 7000
= 15,000

Now, temperature decreases by 18 F for each 5000-foot increase in elevation.
number of times temperature decreased = 15000 / 5000 = 3
Total decrease in temperature = 18* 3 = 54
Temperature at 22000 foot = 41 - 54 = -13 F

Thus, the required temperature at 22,000 feet is -13 F.

(1) Aeroplane A travels 1220 km in 3.5 hours. Aeroplane B travels 830 km in
2.5 hours. Which aeroplane travels faster?

Answers

Answer:

Aeroplane A

Step-by-step explanation:

To find the km traveled per hour, divide 1220 by 3.5 and divide 930 by 8.5. When we do this, we have the numbers 348.571428571 for plane A and 109.411764706 for plane B. Since 348>109, plane A travels faster. I hope this helps!

Which of the following is the y coordinate of the solution of the system of
equations y = - 1/2 x+8 and y=x+ 2?

Answers

Answer:

The y coordinate is 6 and the x coordinate is 4

I hope this helps!

Answer: The whole solution is (4,6) so the y coordinate of the solution is 6.

Step-by-step explanation:

y = -1/2x + 8 and y= x +2

Using both equations substitute one of the equation into another an solve for x.

-1/2x + 8 = x + 2

-8 -8

-1/2x = x -6

-x -x

-1.5x = -6

x = 4

Since the value of x is 4 input in into the equation and solve for y.

y = -1/2(4) + 8

y = -2 + 8

y = 6

the ratio of the measures of the angles of a triangle is 3:4:8 what are the measures of the angles?

Answers

Answer:

36 and 48 and 96

Step-by-step explanation:

add 3+4+8=15

all of the angles in a triangle have to add up to 180

so 180÷15=12

now for this ratio, each part will equal 12

so we have to multiply each of the parts by 12

3×12=36

4×12=48

8×12=96

those are the measures of the angles

you can add them up again and see that they equal 180

you can try dividing and you will see that they also equal the ratio

Im kinda confused on this one please help ANSWER QUICKLY AND WILL GIVE BRAINLIESTA Big YearBy Bob KowalskiWould you go to the ends of the earth to see a bird? What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest?If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want.A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. For most in North America who participate in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast.You may be thinking that looking at birds is silly, but just think about the numbers of the recent record holders and the commitment it takes to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune.Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating.This honesty comes from the fact that most people who want to break such a record know the greatest rewards are not necessarily in winning. Such rewards are in being able to commit a year of your life to doing something you love. Rewards are found in seeing amazing, inspiring creatures like the California Condor or the Magnificent Frigate bird. Rewards also come in spending time with people who, like you, want to spend their time looking to the skies and trees for glimpses of emerald, crimson, or cerulean blue feathered jewels.You don't have to be able to travel a continent to have a big birding experience though. Have a big month. Or a big weekend. Set a personal record, learn to identify the species that live in your part of the world, or try to learn the calls of just two species of birds. You will soon find looking at birds isn't such a strange way to spend your time.Extra! Extra! Backyard BirdingMany schools, families, and young birders across the country participate in the "Great Backyard Bird Count." While not as long as a "Big Year," the "Great Backyard Bird Count" happens every year. It depends on birders and families across the country to watch feeders and other areas in their yards and count the number of birds they see. Unlike the "Big Year," the goal is not to see who can count the most birds. Instead, participants in this event work together to help bird experts get a good idea of how birds are doing. Participants are given checklists and enter their sightings on a website. Called a "citizen-science" project, this event is open to anyone, requires no travel, and happens every year over one weekend in February.Why does the author include explanations for why people compete in a Big Year?
