Note, Katie  .......100% more = 2 times as much....so.......

140%  more  = [100% more + 40% more ] = 2.4 times as much    .....so....

1400 * 2.40   =   3360  lbs.

It's 19, the meme isn't popular anymore, and please waste your time on a different website.

You're welcome! Happy to help:)

If the sec y = 5/4, than the cosy  = 4/5

And   cosx =   sqrt(3^2  - 1^2) / 3 =   sqrt(8)/3

And siny  = 3/5

And

So....

sin(x + y)  =

sinxcosy  + sinycosx =

(1/3)(4/5) +  (3/5)(sqrt(8)/3  =

[4 + 3sqrt(8)] / 15 

There are 44 groups of 6 consecutive numbers from 1 up to, and including, 49

But....since you specify, "between,"   we should subtract 2 of these.....so.......the answer is 42

I just didn t  understand the question but now i understood thanks CPhill and Guest ! :)

If we're multiplying or dividing.....the answer is a minus

If we're adding or subtracting......the sign will be that of the number whose absolute value is greater....

Example

-10  +  6

Absolute value of  -10   = 10      absolute value  of 6  = 6   .....thus, the sign will be negative

So...we take   10   -  6    =  4      and we add the minus sign  =  -4

We can solve this equation, Solveit

30(3/5)^N  =  4      where N is the number of bounces.....  divide both sides by 30

(3/5)^N  = 4/30

(.6)^N  = 2/15    take the log of each side

log (.6)^N  = log (2/15)     and we can write

N log(.6) = log(2/15)     divide both sides by log(.6)

N = log(2/15) / log(.6)

N  ≈ 3.944    

When N = 3.....the ball height = 6.48 ft

When N = 4.......the ball height = 3.88 ft

So......it looks like that on the 4th bounce, the ball will be at a height of less than 4 ft   (B)

My guess is( B), because (3/5)^4 X 30 feet=3.888 feet after the 4th bounce.

18 out of 22 is very good that is 81.8181 percent this shows that it is a good score maybe just do some more revision for the next test thats what I always think.Just make 5 mintues a day to do a little fractions/algebra or angles.

The answer to 9+10=19

I can help with some......

(a) I'm not sure what P(Bc)  refers to   ????  Maybe the complement of B ???

If so.....this is just  1- P(B)  =  1 - .42  = .58

(b) P(A or B)   =  P(A) + P(B)  - P(A and B)  =  .64 + .42  -  .30  = .76

(c) P(A and B) complement  =  1 - P(A and B)  = 1 - . 30  =  .70

(d) P(A l B)    =  P(A and B) / P(B)  =  .30/ .42   =  5/7

(e) P(B l A)  =  P(A and B) / P(A)  = .30 / .64   =  15 / 32

If these are independent events, then

P(A and B)   = P(A) * P(B)

.30  = (.64) * (.42)  ???

.30  = .2688   not true

So.....these events are not independent

CORRECTION TO ABOVE: SORRY ABOUT THAT.

8 1/3 X 1.52=12 2/3 minutes to reach Mars.

Since Mars is about 1.52 times farther away from from the Sun as the Earth is, it therefore takes the light that much longer to reach Mars. Since it takes light about 8 1/3 minutes to reach Earth, then:

8 1/3 X 1.52=9.52 minutes for light to reach Mars.

Close....OliviaPi  ....!!!!

Take it from this step

4 ( x^2 - 7x + 11)  = 0 divide both sides by 4

x^2 - 7x + 11     subtract 11 from both sides

x^2 - 7x   = -11     complete the square 

x^2 - 7x + 49/4  = -11 + 49/4       factor the left side, simplify the right

(x - 7/2) ^2  =  5/4      take ths square root of both sides

x - 7/2  =  (+/-) sqrt(5)/2     add 7/2 to both sides

x = (+/-)sqrt(5)/2 + 7/2

Thanks guys

Solve for x:
4 x^2-28 x+49 = 5

Divide both sides by 4:
x^2-7 x+49/4 = 5/4

Write the left hand side as a square:
(x-7/2)^2 = 5/4

Take the square root of both sides:
x-7/2 = sqrt(5)/2 or x-7/2 = -sqrt(5)/2

Add 7/2 to both sides:
x = 7/2+sqrt(5)/2 or x-7/2 = -sqrt(5)/2

Add 7/2 to both sides:
Answer: | x = 7/2+sqrt(5)/2                           or x = 7/2-sqrt(5)/2

By "square 32", I'm assuming you mean "the square root of 32"?

\(\sqrt{32}\)

Find all the factors of 32.

\(\sqrt{2\times2\times2\times2\times2}\)

Group the pairs of factors together.

\(\sqrt{(2\times2)\times(2\times2)\times2}\)

Seperate the them into their own radicals.

\(\sqrt{2\times2}\times\sqrt{2\times2}\times\sqrt{2}\)

And simplify.

\(4\times\sqrt{2}\)

\(32=4\sqrt{2}\)

Simplify square 32 in a surd form

square of 32 or square root of 32?

32=2^5=4sqrt(2) this is square root of 32

Square of 32 is: 4sqrt(2) X 4sqrt(2)

The formula for the resistivity of a wire is shown below.

\(𝜌=\frac{RA}{L}\)

Where 𝜌 is resistivity, R is resisitance, A is cross-sectional area, and L is length. Simply plug the values you were given into the equation, and solve for R. Make sure that they are all in SI units.

\(1.72\times{10}^{-8}=\frac{0.000016R}{1000}\)

\(R=1.075\Omega\)

annual interest rate if 8000 turned into 12500 in 5 years

12500/8000 = (1+r)^5

is this correct? how do you solve?

Your annual interest rate will be: 9.34% compounded annually. The formula is:

FV=PV( 1 + R)^N

12,500=8,000(1+R)^5 divide both sides by 8,000

1.5625=(1+R)^5 take the 5th root of sides, or (1/5)

1+R=(1.5625)^1/5

1+R=1.0934 subtract 1 from each side

R=.0934 X100=9.34%
