Answer:

92

Step-by-step explanation:

89 x 5 = 445

85 + 92 + 81 + 95 = 353

445 - 353 = 92

The score of the fifth student is 92.

An average is a single number taken as representative of a list of numbers, usually the sum of the numbers divided by how many numbers are in the list.

Now it is given that,

Average of the five students = 89

Scores of four students = 85, 92, 81, and 95

Number of students = 5

Let the score of fifth student be x.

⇒Average of the five students = scores of five students/Number of students

∵scores of five students =Scores of four students + score of fifth student

∴scores of five students = 85+92+81+95+x

⇒scores of five students = 353+x

∴Average of the five students = (353+x)/5

⇒89 = (353+x)/5

or, 445 = 353+x

or, x = 445 - 353

⇒  x = 92

Hence, the score of the fifth student is 92

Answer:

Charlie owns 9,315 ft2 of the land area

Step-by-step explanation:

There are 34,500 ft2 of land shared between Mabel, Adeline, and Charlie.

Mabel owns 26% of the land area, that is:

26*34,500 ft2 / 100 = 8,970 ft2

Adeline owns 47% of the land area, or:

47*34,500 ft2 / 100 = 16,215 ft2

The land owned by Mabel and Adeline is: 8,970 ft2 + 16,215 ft2 = 25,185 ft2

Since the total area land is 34,500 ft2, Charlie owns:

34,500 ft2 - 25,185 ft2 = 9,315 ft2

Charlie owns 9,315 ft2 of the land area

Answer: m∠GHK=80.5,

m∠KHJ=80.5

Step-by-step explanation:

Answer:

I would say both GHK and JHK equal 80.5 degrees. (if it is allowed with decimals).  

Step-by-step explanation:

Bisectors are lines that basically cut an angle in half. Since JHG is the whole angle, the bisector, HK, halves it. So, both GHK and KHJ should be the same, since they both are half of the original angle. As a result, 161 divided by 2 is 80.5 degrees.

Answer:

41 miles

Step-by-step explanation:

the company is saying they will round the number of miles, and charge you that number

when rounding 40.8, you round up to 41

1,2,3,4 rounds down to 0

5,6,7,8,9 rounds up to the next 0 up

The required miles he will be charged for is 41 miles.

Given that,
A car rental service charges customers for the number of miles they travel rounded to the nearest whole mile George travels 40.8 miles
To determine how many miles will he be charged.

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
The customer traveled for 40.8 miles,
Now round it to the nearest whole miles, Since 40.8 where 0.8 is 0.2 near to the 1 so the round of 40.8 become 40.8 + 0.2 = 41

Thus, The required miles he will be charged for is 41 miles.

Answer: its the 4th one. even though its not in the picture, i know im correct because im doing the quiz right now

length=(2x-3)

width=(3x-5)

perimeter=26

perimeter= (2 times length) + (2 times width)

26= 2(2x-2) + 2(3x-5)

26 = 4x - 6 + 6x - 10

26 = 10x -16

26 + 16 = 10x -16 + 16

10 = 10x

10 ÷ 10 = 10x ÷ 10

Answer:

22 dimes

10 quarters

Step-by-step explanation:

$4.70 = 0.25(q + 9) + 0.1d

4.7 = 0.25q + 0.25(9) + 0.1d

4.7 = 0.25q + 2.25 + 0.1d

2.45 = 0.25q + 0.1d

24.5 = 2.5 + d

22 = d = 22 dimes

$4.70 = 0.25(q + 9) + 0.1(22)

4.70 = 0.25q + 0.25(9) + 2.2

4.70 = 0.25q + 2.25 + 2.2

4.70 = 0.25q + 2.25 + 2.2

4.70 = 0.25q + 4.45

0.25 = 0.25q

1 = q

1 q + 9 q = 10 quarters

Check:

$4.70 = 0.25(q + 9) + 0.1(d)

$4.70 = 0.25(1 + 9) + 0.1(22)

$4.70 = 0.25(10) + 0.1(22)

$4.70 = 2.5 + 2.2

$4.70 = 4.7

Answer:

The value in your hand is -18

let the value be x, then the equation is:

x = -8 + (-10)

x = - 8 - 10

x = - 10

the distance of the sum from -8 is the distance between -8 & -10, i.e -8 - (-10) = 2.

Answer:

8:12

Step-by-step explanation:

Another ratio that is equivalent to 4:6 would be 8:12;

   To find another ratio equivalent to another, simply find the multiples of the numbers that make up the ratio.

  Using 2 as multiplier;

   2 ( 4 : 6) = 8 : 12

I am sure of this because when we reduce both ratio to their lowest term, we get the same value;

               4: 6                       8: 12

 divide by 2               divide by 4

               2: 3                       2 : 3

Answer

You bought 7 paperbacks and 3 hardcovers.

Step-by-step explanation: This doesn't seem college level! Jokes aside, you solve this with a system of equations. Your first equation is 10 = p + h, where p stands for the number of paperbacks and h stands for the number of hardcovers. Your second equation is p = 3h - 2, meaning that the number of paperbacks is triple the number of hardcovers minus 2. Now, you just have to plug in p = 3h - 2 into your first equation, and you get 10 = (3h - 2) + h. 4h = 12, and h = 3, meaning the number of hardcovers must be 3. All you have to do now is subtract 3 from 10, and you have 7, which is the number of paperbacks!

Out of the total number of 10 books bought, there were 3 hardcovers and 7 paperbacks

Paperbacks are two less than three times the hardcovers. Assume the hardcovers are x, the paperbacks would be represented as:

= 3x - 2

Solving would give:

10 = Paperbacks + Hardcovers

10 = 3x - 2 + x

10 = 4x - 2

4x = 10 + 2

x = 12/4

x = 3 hardcovers

Paperbacks:

= 10 - 3

= 7

In conclusion, there are 3 hardcovers and 7 paperbacks.
