Naddika [18.5K]

Answer:

The time Don estimated for the job, in hour, is 24 hours

Step-by-step explanation:

Based on his regular hourly rate, Don had estimated :

Estimated cost (C) = $336

Estimated hour of work =x

So, estimated rate in hour (R) = \frac{336}{x}

In fact, it took him 4 hours longer than he estimated, therefore

Factual hour of work = {x+4}

Factual rate in hour (F) = \frac{336}{x+4}

He earned $2 less than his regular hourly rate, hence the factual rate (F) is the subtraction of estimated rate (R) by 2

F = R - 2

Then, substitute F and R,

\frac{336}{x+4} = \frac{336}{x} - 2

\frac{336}{x+4}+2  = \frac{336}{x}

x(\frac{336}{x+4}+ \frac{2(x+4)}{x+4}) = 336

x(336+2(x+4))  = 336 (x+4)

336x+2x^{2} +8x = 336x+336*4

since at the both sides have 336x, we can removed it.

2x^{2} + 8x = 336 * 4

devide both sides by 2, thus

x^{2} +4x = 336 * 2

x^{2} +4x = 672

Make the algebra function equal to 0 by moving the 672 to the left side.

x^{2} +4x - 672 = 0

factorize the function above,

the factor of 672 is 24 and 28, because if it's multiplied it becomes 672 and if it's subtracted equal to 4. since 4x is positive, the higher number (28) should be in positive. Therefore we conclude that

(x+28)(x-24) = 0

x+28=0, x = -28\\x-24=0, x = 24

We takes the positive result, because the time is in positive. so, the estimated time is 24 hours

yarga [219]

Answer:

39%

Step-by-step explanation:

Let's find the answer by using the following formula:

selling price=(paid price)+((paid price)*(percent markup)) which can be written as:

percent markup=((selling price)-(paid price))/(paid price)

percent markup=(27.80-20)/20

percent markup=0.39=39%

In conclusion, the percent markup is 39%.

In △ABC, m∠A=32°, m∠B=25°, and a=18. Find c to the nearest tenth.
olga55 [171]

Trig!!!-

We can use trig function to find the answer-

we know that tangent is opp/adjacent

Thus c=180-32-25=123 degrees and

tan 123=18/c

This c=34.7539008597 since it is tan 123=0.51792747158 and we use algebra to solve for c and it is 18/tan 123=c and then c=34.8 when we round to the nearest tenth
