Curt and Ian both ran a mile. Curt time was 8/9 of Ian time. Who ran faster?
Leona [35]

Curt because if his time was 8/9 of Ian's time then that means he ran the mile in a fraction of Ian's time, so he finished the mile quicker. Curt ran faster.

What is the solution to 2(-4x+1)=2/3(x+2)
Rzqust [24]

Hello!

The answer to your problem is: x=1/13

<u>Simplify both sides of the equation</u>

(2)(-4x)+(2)(1)=(2/3)(x)+(2/3)(2) (Distribute)

-8x+2=2/3x+4/3

<u>Subtract 2/3x from both sides</u>

-8x+2-2/3x=2/3+4/3-2/3x

-26x+2=4/3

<u>Subtract 2 from both sides</u>

-26/3x+2-2=4/3-2

-26/3=-2/3

<u>Multiply both sides by 3/(-26)</u>

(3/26)*(-26/3x)=(3/-26)*(-2/3)

<u>Get your answer</u>

x=1/13

Hope This Helps!

I need to get the left side to equal the right side. Keeping the right side alone and not changing it.
likoan [24]

<u>To prove the trigonometric equation:</u>

\sin ^{3} x+\cos ^{3} x=(\sin x+\cos x)(1-\sin x \cos x)

RHS=(\sin x+\cos x)(1-\sin x \cos x)

We know that \sin^2x +\cos^2x=1, substitute this in place of 1.

       =(\sin x+\cos x)(\sin^2x +\cos^2x-\sin x \cos x)

Multiply each term of the first term with each term of the 2nd term.

       =\sin^3x + \sin x \cos^2x-\sin^2 x \cos x+\cos x \sin^2 x + \cos^3 x-\sin x\cos^2 x

Group like terms together.

       =\sin^3x +( \sin x \cos^2x-\sin x\cos^2 x)+(\cos x \sin^2 x-\sin^2 x \cos x) + \cos^3 x

       =\sin^3x +( 0)+(0) + \cos^3 x

       =\sin^3x + \cos^3 x

       = LHS

RHS = LHS

\sin ^{3} x+\cos ^{3} x=(\sin x+\cos x)(1-\sin x \cos x)

Hence proved.

Tina lives in a state that charges her 4.5% state income tax on her federal taxable income. If her federal taxable income is $61
Irina-Kira [14]

$ 2772 is paid in state income tax

<em><u>Solution:</u></em>

Given that, Tina lives in a state that charges her 4.5% state income tax on her federal taxable income

Federal taxable income = $61,600

<em><u>To find: Amount paid by Tina in state income tax</u></em>

Tax rate = 4.5 %

<em><u>Which means, 4.5 % of $61,600 is paid as tax</u></em>

Tax\ Rate = 4.5 \% \text{ of } 61600

Here, "of" means multiplication or product

Tax\ Rate = 4.5 \% \times 61600\\\\Tax\ Rate = \frac{4.5}{100} \times 61600\\\\Tax\ Rate = 0.045 \times 61600\\\\Tax\ Rate = 2772

Thus $ 2772 is paid in state income tax
