Answer:

rectangle triangle trapezium

Step-by-step explanation:

rectangle =length×width(12×7=84)

triangle=1/2base×height(1/2×8×7=28)

trapezium=1/2sum of parallel lines ×height(1/2×(6+2)×7=28)

area of the rectangle subtract area of two trapeziums. (84-{28×2}=28)

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is two times the measure of the first angle. The third angle is 14 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.

) Ms. Pimentel went on a trip with the Glee Club. The trip was $365. Included in that price are $105 for a plane ticket, the cost of 2 luggage bags, and the hotel room for one night. The hotel room cost two times the amount of the plane ticket. What is the cost of one luggage bag? *

A. $25
B. $50
C. $130
D. $260

Answers

A. $25
The explanation would be because 365-105=206 and then double 105 which would be 210 and then subtract that from 206 which would be 50 then divide that by 2 and you would get 25
Let’s put that into an equation

Luggage bags will be represented in x
Since there’s 2 bags it will be 2x

The plane ticket cost $105. The hotel room cost TWO TIMES the amount of the plane ticket. So the hotel room would be 2(105)

Putting them together your equation would be:

365 = 105 + 2x + 2(105)

Now we solve from here:

2(105) = 210

210 + 105 = 315

Now we have:

365 = 315 + 2x

Isolate the variable so you have to Subtract 315 on both sides then you’ll have:

50 = 2x

Divide 2 on both sides:

25 = x

The cost of one luggage bag is $25.

Answers

Answer:

B 11%

Step-by-step explanation:

The total number of marbles is

12+4+2 = 18

P( blue) = number of blue marbles / total marbles

            = 2 blue/ 18 total

            = 1/9

              =.11111

Bryan owes his friend more than $1,610 from a loan. Bryan has already paid his friend back $206 and continues to pay him $156 each month. Which of the following inequalities could be used to solve for x, the number of months after making the $206 payment that Bryan needs to continue paying back his loan?

Answers

owes more than 1425
owe>1425

owed musbe be equal to how much he paid back

paid back 210

and 153 per month is paid back (represent number of months by x)
so
owe=210+152x

210+153x>1425

You are a waiter at a restaurant. A family had a bill of $116.17. They leave you a 20% tip. How much of a tip did you get?

Answers

Answer:

Hello there! :) The tip they would leave you would be of $23.23

Step-by-step explanation:

The first step is to devide 116.17 by 100, which would equal 1.1617, which is obviously not your answer or a valid amount of money. But, you now take this 1.1617 by 20. Why? Becuase 20% is the same as 20 out of 100. Now you multiply 1.1617 × 20 and you will get $23.23.

Example on how to solve:


To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.

To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.

Simplify 3.1n - 1.1n

Answers

Answer:

2n

Step-by-step explanation:

The solution is, the value of subtraction is 2n.

What is Subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given expression is,

3.1n - 1.1n

we have to solve it, by subtraction.

now, we have,

3.1n - 1.1n

= (3.1 - 1.1 ) n

= 2 * n

=2n

at first, we take n common from both terms, then subtract 3.1 from 1.1, which is 2, then multiply the result 2 with n, finally we get the answer as 2n.

Hence, The solution is, the value of subtraction is 2n.
