could you guys pleasenname the place value to which each number was rounded. 0.982 to 0.98

Answer:

x = 6

Step-by-step explanation:

Solve for x:

36 (x - 5) = 9 x - 18

Expand out terms of the left hand side:

36 x - 180 = 9 x - 18

Subtract 9 x from both sides:

(36 x - 9 x) - 180 = (9 x - 9 x) - 18

36 x - 9 x = 27 x:

27 x - 180 = (9 x - 9 x) - 18

9 x - 9 x = 0:

27 x - 180 = -18

Add 180 to both sides:

27 x + (180 - 180) = 180 - 18

180 - 180 = 0:

27 x = 180 - 18

180 - 18 = 162:

27 x = 162

Divide both sides of 27 x = 162 by 27:

(27 x)/27 = 162/27

27/27 = 1:

x = 162/27

The gcd of 162 and 27 is 27, so 162/27 = (27×6)/(27×1) = 27/27×6 = 6:

Answer:

20 degrees.

Step-by-step explanation:

The 3 angles of a triangle add up to 180 degrees.

Therefore the third angle in this triangle

= 180 - (120 + 40)

= 180 - 160

= 20 degrees.

Answer:

The equation is

(x+27)= 58

Therefore the customer purchased 31 bananas

Step-by-step explanation:

Given , A customer at the grocery store purchased 27 apple and unknown number of bananas. The customer purchased a total of 58 apple and bananas.

Let the number bananas be x

He purchased a total (x+27)  apples and bananas.

According to the problem,

(x+27)= 58

⇔x= 58-27

⇔x = 31

Therefore the customer purchased 31 bananas

Answer:

x = 1

Step-by-step explanation:

Step 1:  Choose one of the equations to solve for y:

x - y + 1 = 0

(-y) / -1 = (-1 - x) / -1

y = 1 + x

Step 2:  Plug in y into either equation

3x + 2(1 + x) = 7

3x + 2 + 2x - 2= 7 - 2

5x / 5 = 5 / 5

x = 1

Answer:  x = 1

Answer:

3468

Step-by-step explanation:

We can make four digit number from the digits 6,4,3,8

Smallest digit for thousands is 3=3000

Smallest digit for hundreds (out of remaining 6,4,8) is 4 = 400

Smallest digit for tenths (out of remaining 6,8) is 6= 60

And unit digit is 8

So the smallest number is 3000+400+60+8=3468 answer

Final answer:

The median rainfall for the highland storms is 19 mm and for the lowland storms is 13 mm.

Explanation:

To find the median rainfall for the highland storms, we need to locate the middle value in the dot plot. Since there are 14 observations, the median is between the seventh value, 18, and the eighth value, 20. To find the median, add the two values together and divide by two: (18 + 20) / 2 = 19.

To find the median rainfall for the lowland storms, we also need to locate the middle value in the dot plot. Since there are 14 observations, the median is between the seventh value, 12, and the eighth value, 14. To find the median, add the two values together and divide by two: (12 + 14) / 2 = 13.

Answer:

2i

Step-by-step explanation:

The square root of -4 is equal to 2i.

The square root of -4 can be simplified using the imaginary number i. Since the square root of a negative number is not defined in the set of real numbers, we use i to express it, where i is defined as the square root of -1. Thus, the square root of -4 is calculated as follows:
√-4 = √(-1*4)
= √(-1) * √(4)
= i * 2
= 2i

This result shows that 2i is the simplified form of the square root of -4 using the imaginary number i.

Answer:

22.5

Step-by-step explanation:

1) Arrange the numbers in order by size.

(5,5,5,10,10,15,15,20,25,30,35,40,40,45,50,50)

2) If there is an odd number of terms, the median is the center term.

3) If there is an even number of terms, add the two middle terms and divide by 2.

(25+20=45)

45 divided by 2 is 22.5

22.5 is your median

21+1.7+0.25=22.95

You add 21+1.7, which equals 22.7, then add 0.25 to get 22.95.

==============================

Work Shown:

d = number of dimes

n = number of nickels

10d = value of all the dimes in cents

5n = value of all the nickels in cents

10d+5n = total value of all the coins in cents

$3.30 = 3.30*100 = 330 cents

so one equation is 10d+5n = 330

-------

Let's set up the second equation

we have 42 coins, so n+d = 42

subtract d from both sides to get n = 42-d

-------

Go back to the first equation and apply substitution to solve for d.

10d+5n = 330

10d+5(42-d) = 330 ... plug in n = 42-d

10d+5(42)+5(-d) = 330 ... distribute

10d+210-5d = 330

5d+210 = 330

5d = 330-210 ... subtract 210 from both sides

5d = 120

d = 120/5 ... divide both sides by 5

d = 24

-------

Now we can use that to find n.

n = 42-d

n = 42-24 ... plug in d = 24

n = 18

------

Check:

n = 18 nickels

5*n = 5*18 = 90 cents from just the nickels

d = 24 dimes

10*d = 10*24 = 240 cents from just the dimes

5n+10d = 90+240 = 330 cents = $3.30 total from all the coins

n+d = 18+24 = 42 coins total

Answers are confirmed

Final answer:

To solve the question, set up a system of linear equations based on 0.10d + 0.05n = 3.30 and d + n = 42. Solve the system to find there are 33 dimes and 9 nickels in the collection.

Explanation:

The question involves solving a system of linear equations based on the given conditions involving dimes and nickels. To find out how many of each kind of coin there are, we can set up the following equations using the facts provided:

Let d be the number of dimes.

Let n be the number of nickels.

Since the total value is $3.30, we can write the equation: 0.10d + 0.05n = 3.30 (since a dime is worth 10 cents and a nickel is worth 5 cents).

We are also told that there are 42 coins in total, which gives us the equation: d + n = 42.

Now we have a system of equations:

0.10d + 0.05n = 3.30

d + n = 42

To solve this system, we can multiply the second equation by 0.10 to make the coefficient of d the same in both equations:

0.10d + 0.05n = 3.30

0.10d + 0.10n = 4.20

We then subtract the first equation from the second to eliminate d:

0.10n = 0.90

n = 9 nickels

Plugging n = 9 into the second original equation d + 9 = 42, we get:

d = 42 - 9

d = 33 dimes

Therefore, there are 33 dimes and 9 nickels in the collection.

Answer:

Length = 39 inches , breadth = 13 inches

Step-by-step explanation:

Given:

The perimeter of a rectangular atrium is 104 inches.

The length of the atrium is three times the width.

Question asked:

The length and the breadth of rectangular atrium = ?

Solution:

Let breadth of rectangular atrium = [tex]x[/tex]

Then, the length of rectangular atrium = [tex]3x[/tex]    (given)

Perimeter of rectangle = [tex]2\times(length + breadth)[/tex]

                               [tex]104 = 2\times( 3x + x )[/tex]

                               [tex]104 = 2\times 4x[/tex]

                               [tex]104 = 8x[/tex]

Dividing both side by 8

                               [tex]13 = x[/tex]

breadth of rectangular atrium = [tex]x[/tex] = 13 inches

length of rectangular atrium = [tex]3x[/tex] = [tex]3 \times13 = 39[/tex] inches

Thus, length and the breadth of rectangular atrium are 39 and 13 inches.
