Perform each operation. Express your answers the the correct number of significant figures
a.61.2 meters + 9.35 meters +8.6 meters
b.9.44 meters - 2.11 meters
c.1.36 meters + 10.17 meters
d.34.61 meters - 17.3 meters
Step-by-step explanation:
no calculator available ?
this is pure number typing. no problem to be solved, no trick or hidden meaning to be considered, nothing.
at least the way you were typing the "problem" definition. as there are clearly some issues with the phrasing, maybe something was missed.
but here it goes :
61.2 + 9.35 + 8.6 = 79.15 meters
9.44 - 2.11 = 7.33 meters
1.36 + 10.17 = 11.53 meters
34.61 - 17.3 = 17.31 meters
The solution to the operations are:
a 79.15 meters
b. 7.33 meters
c.11.53 meters
d. 17.31 meters
This '+' is the addition sign. For numbers that have this sign, add the numbers together. This '-' is the subtraction sign. For numbers that have this sign, subtract the numbers from each number.
In order to round off to two significant numbers, the numbers after the decimals should be two non-zero digits.
a 61.2 meters + 9.35 meters +8.6 meters = 79.15 meters
b. 9.44 meters - 2.11 meters = 7.33 meters
c. 1.36 meters + 10.17 meters = 11.53 meters
d. 34.61 meters - 17.3 meters = 17.31 meters

please show all work!
Answer:
[tex] \displaystyle - 3 \sqrt{5n} + 4 \sqrt{15} n[/tex]
Step-by-step explanation:
we would like to simplify the following expression:
[tex] \displaystyle \sqrt{15} ( - \sqrt{3n} + 4n)[/tex]
recall distribution property thus:
[tex] \displaystyle - \sqrt{3n} \sqrt{15} + 4n \sqrt{15} [/tex]
remember that,
[tex] \displaystyle \sqrt{a} \sqrt{b} = \sqrt{ab} [/tex]so assign variables:
[tex]a \implies 3n[/tex][tex]b \implies 15[/tex]simplify Multiplication:
[tex] \displaystyle - \sqrt{45n} + 4 \sqrt{15} n[/tex]
rewrite 45 as 9×5:
[tex] \displaystyle - \sqrt{9 \times 5n} + 4 \sqrt{15} n[/tex]
utilize the formula:
[tex] \displaystyle - \sqrt{9 } \sqrt{5n} + 4 \sqrt{15} n[/tex]
simplify square:
[tex] \displaystyle \boxed{- 3 \sqrt{5n} + 4 \sqrt{15} n}[/tex]

Answer:
CStep-by-step explanation:
This is because,
As,
Negative integers are -1, -2, -3, -4, -5 .......
Also,
0 is neither negative integer nor positive integer,
And,
Positive integers are 1, 2, 3, 4, 5 .........
Therefore here ,
We get two sets of NON - POSITIVE INTEGERS,
That is 0 ( neither negative nor positive) and -1, -2, -3, -4, -5 ........ (Negative integers)
So,
Set of ( .......... -5, -4, -3, -2, -1, 0 ) is non - positive integers.
Answer:
C
Step-by-step explanation:
We are given 5 negative values plus 0. Keep in mind that 0 is not positive or negative. A non-positive integer is any negative number plus zero which the set follows. C is the only logical answer. A is incorrect because a negative number cannot be a whole number. B is incorrect because while we have negative values, we also have 0 and as stated previously, its not a negative or positive value. D is also incorrect because a non-negative integer is any positive value and zero but again, we don't have any positive values.
Best of Luck!

Step-by-step explanation:
10×n-15
10×50-15
485
Answer:
12,000.
Step-by-step explanation:
First term = 10(1) - 15 = -5
50th term = 10(50) - 15 = 485
Sum of 50 terms = (50/2)(-5 + 485)
= 25 * 480
= 12,000

If R is the midpoint of OS , RS = 2x - 4, ST = 4x – 1, and RT = 8x – 43, find QS.
Answer:
56
Step-by-step explanation:
The numerical length of QS is 128.
We have a Line Segment QT and a point R lies on the midpoint of QS.
We have to determine length of QS.
What is Mid - Point of a line?The mid - point of a line is a point that divides it into two parts of equal lengths.
According to question, we have -
RS = 2x - 4
ST = 4x – 1
RT = 8x – 43
Since, R is the midpoint of QS -
QR = RS = 2x - 4
QS = QR + RS = 2 x QR = 2(2x - 4)
Now -
ST = RT - RS
ST = 8x - 43 - 2x + 4
ST = 6x - 39
and
ST = 4x - 1 [Given]
Therefore -
6x - 39 = 4x - 1
6x - 4x = - 1 + 39
2x = 38
x = 19
Now -
QS = QR + RS = 2RS
QS = 2(2x - 4) = 2( 2 x 19 - 4) = 2(38 - 4) = 2 x 34 = 128
Therefore - QS = 128
Hence, the numerical length of QS is 128.

Answer:
Rs 525.5518.5%Step-by-step explanation:
Given:
Rate of interest is rTime = 2 yearsSum = PP(c) = 738P(s) = 720Use formulas:
P(c) = P*(1 + r)²P(s) = P*(1 + r*2)Substitute the known values:
P(1 + r)² = 738 ⇒ P = 738/(1 + r)²P(1 + 2r) = 720 ⇒ P = 720/(1 + 2r)Eliminate P and solve for r:
738/(1 + r)² = 720/(1 + 2r)738(1 + 2r) = 720(1 + r)²Solving the quadratic equation we get:
r ≈ 0.185 (or 18.5%)Now find P:
P = 720/(1 + 0.185*2) ≈ 525.55Solve the equation shown. 12+3/5x-4=29

Joan joined her school's band. She bought a viola for $72.21, and a song book
which was $7.25 with a $100 bill. How much change was Joan given?
Hello :D
To do this you need to add the cost of the violin and the song book.
$72.21 + $7.25 = $79.46
$100 - $79.46 = $20.54
The answer is $20.54. I hope this helps :)
