Answers

Answer:

C

Step-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.

Answer:

Rs 525.5518.5%

Step-by-step explanation:

Given:

Rate of interest is rTime = 2 yearsSum = PP(c) = 738P(s) = 720

Use 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)²

Solving the quadratic equation we get:

r ≈ 0.185  (or 18.5%)

Now find P:

P = 720/(1 + 0.185*2) ≈ 525.55

b.9.44 meters - 2.11 meters
c.1.36 meters + 10.17 meters
d.34.61 meters - 17.3 meters

Answers

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

If R is the midpoint of OS , RS = 2x - 4, ST = 4x – 1, and RT = 8x – 43, find QS.

Answers

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.

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?

Answers

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 :)

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:
