*By*:-

solve for x

-3e^9x-1+6=-58 - What is 128/3.2?
*By*:-

1280 / 32 = 320 / 8 = 40

40

128/3.2 = 40

40.

Get rid of the decimal by moving the decimal point one place to the right in bo - what is 2/5 interest of 20,000 at 16 percent interest?
*By*:-

2/5 x 16/100 x 20000

2/5 x 16 x 200 = 2 x 16 x 40 = 1280

2/5 of 20,000 is 8,000 and 16% of 8,000 is 1,280

6400/5 = 1280

I don't - A model rocket is launched from the roof of a building?
*By*:-

the flight path is h=-5t^2+30t+10. h is the height of the rocket about the ground in meters and t is the time measured in seconds after the launch. What is the maximum height and and how long does it take for the rocket to land? - 3(x+1)=15?
*By*:-

3(x + 1) = 15

3x + 3 = 15

3x = 12

x = 4.

3(x+1)=15

x+1=15/3

x+1=5

x=5-1

x=4

Answer: 4

3(x + 1) = 15

x + 1 = 5

x = 4

- When a fair coin is flipped 100 times, will we always get close to 50 heads or tails? It's alway
*By*:-

When flipping a fair coin infinitely many times

the probability that getting a head or tail=1/2.

Basing on this, we have, getting 50 heads in

flipping 100 - 2v^2-5v+11=(v+1)2?
*By*:-

2v² - 5v + 11 = (v + 1)²________presumably ?

2v² - 5v + 11 = v² + 2v + 1

v² - 7v + 10 = 0

[ v - 5 ] [ v - 2 ] = 0

V = 2 , v = 5

2v² - 5v - What's the value of sin(2x) if tan x = 0.8 and sin>0?
*By*:-

sin(2x)>0=> 2x is in the 1st or the 2nd quadrant.

tan x=0.8=>x=38.6598082...=>2x=77.3196165...

Thus sin(2x)=sin(77.3196165..)=0.97561 approximately.

- How do you figure this out?
*By*:-

At Harry's discount Hardware, everything is sold for 20 percent less than the price marked. If Harry buys tool kits for $80, what price should he mark them if he wants to make a 20 percent profit on his costs? - how many 1/10s are in 3?
*By*:-

30

30.

3 = 30/10 = 30 x 1/10

How many 1/10ths are in 3?

How many 10/10ths are in 30?

How many 1s are in 30?

30

3 - 15 tenths as decimal?
*By*:-

1.5

15/10 = 1.5

1.5

15/10 = 1 • 5

.15

15/10 = 1 5/10 = 1.5

15/10 = 3/2 or 1.5 as a decimal.

Orig - How many whole numbers are less than 100 000?
*By*:-

{0, 1, ..., 99999}

100000 whole numbers are < 100000

Whole number is defined as 0,1,2,3,....as I know.

Thus, the answer is 100000.

https:/ - 16.For quadrilateral ABCD, determine the most precise name for it. A(-2,3), B (9,3), C(5,6) and D(2,
*By*:-

A & B lie on y=3 and are 11 units apart, with the midpoint (7/2, 3)

C & D lie on y=6 and are 3 units apart, with the midpoint (7/2, 6)

The line throught the - If A pack 5 pies in each box, A will have 4 pies left. If A pack 9 pies in each box, she will have 8
*By*:-

More ESL English.

I'm always wondering who is asking these random, unsolvable questions.

Let x be the number of pies, then

x=5M+4

x=9N+8

where - Divide 585 in to ratio 1:3:5?
*By*:-

Numbers: a - b - c in the ratio: 1 - 3 - 5

a/b = 1/3

b/c = 3/5

a + b + c = 585 → where: b/c = 3/5 → c = (5/3).b

a + b + (5/3).b = 58 - what is 1/3-1/4=?
*By*:-

4/12 - 3/12 = 1/12.

1/12

Multiply it by 12 and get 4 - 3 which is 1.

Now divide by 12 to compensate and get final answer:

1/12.

You did not know seriously

The answer is 5

4 - 2 + 3 =

3

4 - 2 + 3 = 2 + 3 = 5

*By*:-

yes, correct.

Ans. right.

30 x $ 1•53 = 3 x $ 15•30 = $45•90____as you suggest

The given answer is correct at $45.90

1, 3, 7, 13, 21, _,_,_ - 1/4 of 400 =?
*By*:-

100

1/4 of 400 = (1/4) x 400 = 400/4 = 100 (Ans.)

100

400 / 4 = 100

40 - s=4t^4+5t+4What is the velocity of the object when t=9? Give your answer in mm s-1 to the nearest in
*By*:-

Assuming S = distance and t = time (you haven't specified)

S '(t) = 16t^3 + 5

S '(9) = 19(9^3) + 5 = 11669

Assuming t is in seconds and S is in mm - How do I simplify: 1 divided by (4 + square root of 3)?
*By*:-

1/(4+rt3) = (4-rt3)/[(4-rt3)(4+rt3)] = (4-rt3)/(16-3) = (4-rt3)/13.

1 / (4 + square root 3) =

1 / (4 + 1.73205) =

1 / 5.73205 =
