A plane ticket to Barcelona costs £175 the price decreases by 6%

To find:

The new price of the plane ticket

Solution:

The ticket to Barcelona costs £ 175

The price decreases by 6%

⇒ 6% = 6/100 = 3/50

The new price of the plane ticket is decreased by the amount,

= £ 175 × 3/50

= £ 10.5

Therefore, the new price of the plane ticket is given by,

= £ 175 - £ 10.5

Help plz mportant!!! Choose the point-slope form of the equation below that represents the line that passes through the point (-1.6) and has a slope of -3.
а. y - 6 = -3x - 3
b. y - 6 = -3(x + 1)
c. y=-3x + 3
d. 3x+y=3​

Answers

Answer:

B

Step-by-step explanation:

point slope uses the form y - y1 = m(x - x1)

m stand for slope. in this case it is -3

x1 is -1 and y1 is 6

when you plug it in, you get

y - 6 = -3(x - [-1])

which simplifies to your final answer: y - 6 = -3(x + 1)

If they instead chose front and back covers of thickness 1/3 of an inch, how would this change the equations in the previous two parts

Answers

Answer:

where is the rest of the question

Step-by-step explanation:

Answer:

y = 1/2 + 1/4*x

Explanation:

Given that the front cover has a thickness of 1/4 an inch and back cover also has a thickness of 1/4 an inch, then, the addition of both gives to the book thickness of 1/4 + 1/4 = 1/2 inch, despite how many pages it has.

Given that for every hundred pages a thickness of 1/4 inch is added to the book, then the equation is:

y = 1/2 + 1/4*x

where y refers to the width of the book, and x refers to every hundred pages printed on bond paper. Y is measured in inches.

Add a colon to the end of the statement Begin the statement with the keyword count Change the parentheses around the test condition to quotation marks Use quotation marks around the relational operator

Answers

Answer:

Add a colon to the end of the statement

Step-by-step explanation:

Given

x = 1

while(x < 26)

   print(x)

   x = x + 1

Required

Spot and fix the error

Every lines of the given code segment is correct except the second line.

The syntax of a while loop is:

while(condition):

Comparing while(condition): to while(x < 26),

we'll see that while(x < 26) has a missing colon.

So, the error in the program is a missing colon and the solution is (option a) adding a colon to the end of the while statement

So, the correct code segment is:

x = 1

while(x < 26):

   print(x)

   x = x + 1

As an exercise for her students, she had them graph her total weekly pay in dollars as it relates to her number of hours worked. Now you will do the same. (6 points: Part I - 1 point; Part II - 2 points; Part III - 1 point; Part IV - 2 points)
Part I: What equation models the tutor's total weekly pay y in dollars as it relates to the number of hours x that she has worked if the tutor has worked 40 hours or fewer?








Part II: What equation models the tutor's total weekly pay y in dollars as it relates to the number of hours x that she has worked if the tutor has worked more than 40 hours?

If you go out to eat with 3 friends and you mea was $72.50 there is a 6.75% slaes tax and you should tip the waiter 15% how much should each person pay.

Answers

Answer:

$29.42

Step-by-step explanation:

Total cost of meal for the 3 friends = $72.50

sales tax = 6.75%

percent tip = 15%

Total %paid on meal = 6.75%+15% = 21.75%

Increment paid = 21.75% of  $72.50

Increment paid =  21.75/100 * 72.50

Increment paid = 21.75 * 0.7250

Increment paid = $15.7685

Total amount paid = original cost + increment

Total amount paid = $72.50+$15.7685

Total amount paid = $88.26875

If the 3 friends paid $88.26875

Each person will pay $88.26875/3 = $29.42

Hence each person will pay $29.42

X+123°=180°(BEING DUM OF CO INTEROIOR ANGLES IS EQUAL TO 180°)

X=180°-123°

X=57°

Hi!

x = 57 degrees.

Explanation:

There is a straight line, so that must mean there is a linear pair. We know the first part of that pair is 123 degrees. The linear pair adds up to 180 degrees. Subtract 123 from 180 to get 57.

That angle and x are alternate interior angles, so they are equivalent.

Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries

Answers

Answer:Megan spent 0.15 pounds more on bananas than strawberries

Step-by-step explanation:

Step 1

Cost of bananas = 2 1/4 pounds of bananas for 0.80 per pound

2 1/4 x 0.80 = 1.8 pounds

Cost of strawberry= 1 1/2 pounds of strawberries for 1.10 per pounds

1 1/2 x 1.10  = 1.65.

Step 2  how much  more means the difference between the cost of bananas and strawberry .

 Therefore, we have Cost of bananas - cost of strawberries

1.80 pounds - 1.65 pounds=0.15

Megan spent 0.15 pounds more on bananas than strawberries

Polythene shopping bags and wrappers are a potential threat to urban environment. Once you have discarded them after use, you do not lose your link with them. They return to you in a variety of ways, though you do not realise it. For example, they choke your drains and provide breeding facilities to deadly germs.ii. A recent study has shown that about 250 tonnes of plastic waste come out of various colonies of major cities every day. This disrupts the sewer system, the essential arteries of city life, choke the land mass and clog the pores of the wetlands.iii. Unfortunately, even the villages and small towns are not free from this danger. Millions of people returning to their home towns everyday carry their shopping in colourful bags. This pleases their family and children, who after preserving them for a time dispose them in wells, rivers, tanks and drains. Many throw them off into the fields. They do it with a sense of pride, to show off. When their neighbours see that their men from the cities regularly send them those good things of life, they are impressed.iv. All over the world the worst offenders are the upper income groups of the so-called posh colonies. Though educated, the residents of these affluent areas are unaware of the damage done by the plastic bags. Millions of children in schools carry their lunch boxes in plastic bags. They callously throw them away and cause an unhealthy environment.v. As it is convenient for mothers to wrap the food in plastic, it is difficult to persuade them against doing this. According to a drill master of a school, it becomes a drill to clean the fields after the children leave. When the midday meal scheme is fully implemented, it must be seen that no plastic wrappers are used.vi. As these wrappers are light in weight, they are borne aloft by the wind causing visual shocks.
