Answer 1

The square root of 89 is an irrational number with never-ending digits

Solution :

Real numbers :

Real numbers are the sets of rational numbers and irrational numbers taken together

Irrational numbers:

Irrational numbers are the set of all numbers that are not rational; they cannot be written as either a terminating or repeating decimal; they cannot be expressed as a fraction of two integers.

or,

The set of irrational numbers is the set of numbers that are not rational, are non repeating, and are non terminating. Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.

1)65.555

Statement:65.555....is rational and a repeating decimal

2)-57

Statement: It is a negative integer.

3)[tex]\sqrt{89}[/tex]

Statement:

Due to the nature of its non-repeating and non-terminating decimal expansion, the square root of 89 cannot be written in the form of p/q, hence, it is an irrational number.

The value of the square root of 89 in decimal form is 9.433981.. so on, The square root of a number can have two values, a positive and a negative value. So, √89=+9.433981. Hence, The square root of 89 is an irrational number with never-ending digits.

Step 1: Divide the number 89 by 9, (because 92 =81 is a perfect square number just less than 89).

Step 2: The divisor and the quotient need to be the same numbers; in this case, it is 9. Multiply the quotient and the divisor and subtract the result from 89.

Step 3: For the next divisor, add the previous divisor with the quotient. (9 + 9 = 18); place it as the new divisor with a blank on its right.

Step 4: Put a decimal after the quotient '9' and bring down two zeros to place it after 8 so that it becomes 800. (184 × 4 = 736). Subtract 736 from 800.(800 − 736 = 64)

Step 5: Bring down another pair of zeros and place it after 64, so that it becomes 6400. Take the new quotient 4 and add it to 184. (184 + 4 = 188)

Step 6: Repeating the above steps, we need to fill the blank with a number such that when the new divisor is multiplied by the new quotient, the product is less than or equal to the dividend 6400. (1883 × 3 = 5649)

Step 7: Write the same number after 4 in the quotient. Subtract 5649 from 6400. (6400 − 5649  = 751)

Step 8: Repeat the process until we get the remainder equal to zero. The square root of 89 up to two places is obtained as 9.43 by the long division method.

Which equation has 1 solution.
A. 10x + 2x = (10 + 2)x - 2
B. 10x + 2 = (10 + 2)x - 2x
C. 10x + 2x = (10 + 2)x
D. 10x + 2 = (10 + 2)x

Answers

Answer:

We conclude that  10x + 2 = (10 + 2)x has only 1 solution.

Hence, option (D) is correct.

Step-by-step explanation:

A.

10x + 2x = (10 + 2)x - 2

Checking the equation in Part A

10x + 2x = (10 + 2)x - 2

10x + 2x = 10x+2x-2

10x + 2x - 10x - 2x = -2

0 = -2

The sides are not equal.

Hence, NO SOLUTION!

B.

10x + 2 = (10 + 2)x - 2x

Checking the equation in Part B

10x + 2 = 10x+2x - 2x

10x + 2 - 10x - 2x + 2x = 0

2 = 0

The sides are not equal.

Hence, NO SOLUTION!

C.

10x + 2x = (10 + 2)x

Checking the equation in Part C

10x + 2x = 10x+2x

10x + 2x - 10x - 2x = 0

0 = 0

Both sides are equal.

It is true for all x.

D.

10x + 2 = (10 + 2)x

Checking the equation in Part D

10x + 2 = 10x+2x

10x - 10x - 2x = -2

-2x = -2

Divide both sides by -2

x = 1

Hence, 10x + 2 = (10 + 2)x has only 1 solution.

Therefore, we conclude that  10x + 2 = (10 + 2)x has only 1 solution.

Hence, option (D) is correct.

sin70° sin130° sin170°=1/8​

Answers

Sin 10° Sin 50° sin 70° = 1/8
Now we multiply upper & bottom both side 2/2

then

➡ 1/2 (2sin 10° sin50° 70°)

➡ 1/2 sin10°( 2sin70° sin50°)

we know that
2 sinA sinB = cos (A-B) - cos (A+B)

Then

➡ 1/2 sin 10° ( cos 20° - cos 120°)

➡ 1/2 sin 10° ( cos 20° - cos (90°+30°))

➡ 1/2 sin 10° ( cos 20° +1/2)

➡ 1/2 sin 10° cos 20° +1/4 sin 10°

again we multiply both upper & bottom side 2/2 so

➡ 1/4 ( 2 sin 10° cos 20°). + 1/4 sin 10°

we know that
2 sinA cos B = sin (A+B) - sin (A- B)

➡ 1/4 (sin 30° - sin 10°) + 1/4 sin 10°

➡ 1/4 sin 30° - 1/4 sin 10° + 1/4 sin 10°

we know sin 30° = 1/2

➡ 1/4 × 1/2

Which number is not an appropriate result?
A - a shopping receipt that totals $4.90

B - a soccer game where the average score is 4.7

C- a stack of 15.6 watermelons

D- a classroom with 24 students

Answers

Answer:

C - a stack of 15.6 watermelons

Step-by-step explanation:

Lets first go through each option:

"A shopping receipt that totals $4.90":

This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.

"A soccer game where the average score is 4.7":

This is also an appropriate result since it is the average score of a soccer game, so finding a decimal is appropriate.

"A stack of 15.6 watermelons":

This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.

"A classroom with 24 students":

This is an appropriate result since the number of students is a whole number not a decimal.

Hope this helps :)

Answer:

-1 5/6

Step-by-step explanation:

-2/3 + (-1 1/6)

Look carefully at he number line. Each space between whole numbers is divided into 6. That means that from one mark on the line to the very next one, the distance is 1/6.

Start at -2/3. Since we are dealing with 1/6's, convert -2/3 to 6ths.

-2/3 * 2/2 = -4/6

-2/3 is the same as -4/6, so start at -4/6. Locate 0 on the number line, and move 4 marks to the left. That is -4/6 which is the same as -2/3 and is your starting point.

Now you need to add -1 1/6. Adding a negative number is the same as subtracting a positive number. Adding -1 1/6 is the same as subtracting 1 1/6. That means you need to go left 1 1/6. Since each unit is divided into 6 equal parts, 1 1/6 is 7 marks on the number line. Starting at -4/6, count 7 marks to the left. Where you end up is the answer which is -1 5/6.

Answer: -2/3 + (-1 1/6) = -1 5/6

Your equation should be like this: 3x + 17 + 2x +21 = 10x -1

than you solve form there

I;m not sure that this is the correct answer and maybe i'm wrong, but hope this helps

Answer:

59°

Step-by-step explanation:

According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]

So, by exterior angle property of a triangle, we have:

[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\

(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\

(10x - 1)\degree = (3x +17+2x +12)\degree\\\\

(10x - 1)\degree = (5x +29)\degree\\\\

(10x - 1)= (5x +29)\\\\

10x - 5x = 29 + 1\\\\

5x = 30\\\\

x = \frac{30}{5}\\\\

x = 6\\\\

\because m\angle QRS = (10x - 1)\degree \\\\

\therefore m\angle QRS = (10\times 6- 1)\degree \\\\

\therefore m\angle QRS = (60- 1)\degree \\\\

\huge\orange{\boxed{\therefore m\angle QRS = 59\degree }}\\

The location of Sam's house, the library, and the gas station are shown on the map below.
Based on the map, what is the shortest distance, to the nearest tenth, from the Library to the Gas Station if each unit represents one mile?

Answers

It is found that location of Sam's house is at a distance of approximately 8.062 meters far from the gas station.

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]  

Sam's house S(x, y) = (2, -4)

Library L(x, y) = (-5 , 2)

Gas station  G(x, y) = (3, 4)

The distance d, in miles, is determined by the line segment distance formula:

D = √[(x-p)² + (y-q)²]  

It is used in an operation known as dot product.

Then the distance between Sam's house and the Gas station is:

D = √[(2 - 3)² + (-4 -4)²]  

D = 8.062 meters

Hence, The location of Sam's house, is at a distance of approximately 8.062 meters far from the gas station.

Answer: 131

Step-by-step explanation:

The angle A inside the triangle is

180-162 = 18 degrees

The measure of angle N inside the triangle is

180 -  149 = 31 degrees

Now, since we have the inside angles we can find ang P

Inside Ang A + Inside Ang N + Ang P = 180

18 + 31 + P = 180

49 + P = 180

P = 180 - 49

P = 131 degrees

A fruit stall sells three kinds of fruits - apples, oranges and pears.

The ratio of the money earned from oranges and pears is 1 : 4. How much money did the fruit stall earn from the apples?

Answers

The fruit stall earns 96 dollars from the apples.

How to find how much money the fruit stall earn from the apples?

The fruit stall sells three kinds of fruits which are apples, oranges and pears.

Therefore,

The amount of money earned from selling apples and oranges is $372.

The amount of money earned from selling apples and pears is $480.

The ratio of the money earned from oranges and pears is 1 : 4

Therefore,

let

x = amount earned on apples

y = amount earned on oranges

z = amount earned on pears

Therefore,

x + y = 372

x + z = 480

The ratio of  the money earned from oranges and pears is 1 : 4. Hence,

x : z

x : 4x

where

z = 4x

Therefore,

x + 4x = 480

5x = 480

x = 480 / 5

x = 96 dollars

Therefore,  the fruit stall earns 96 dollars from the apples.

Answers

Answer:

5

Step-by-step explanation:

Given that:

Total maximum amount that the owner wishes to spend = $20000

Average price of each car = $4000

To find:

How many cars that the owner can expect to buy?

Solution:

Total number of cars that the owner can expect to buy can be found by dividing the total money available with the owner with the average price of each car.

i.e.

[tex]\text{Number of cars expected to be bought} = \dfrac{\text{Total money available with the owner}}{\text{Average Price of car}}[/tex]

We have the following values as given in the question statement:

Total money available = $20000

Average price of car = $4000

Therefore, the answer is:

[tex]\text{Number of cars expected to be bought} = \dfrac{20000}{4000} = \bold{5}[/tex]

The owner can expect to buy 5 number of cars.
