Answer:

$3562.50

Step-by-step explanation:

If the cost ratio is ...

labor : parts = 3/5 : 1 = 3 : 5

then the ratio of labor to the whole cost is ...

labor : total = 3 : (3+5) = 3 : 8

The amount saved by not paying for labor is ...

(3/8) × $9500 = $3562.50 . . . labor charge

I’m guessing it is 1 million because you can only round up since it’s value is not above 1 million.

Mr. Smith is paid $9. 50 per hour for fixing watches. Write an expression for the amount of money Mr. Smith earns in h hours. In

IrinaK [193]

Answer:

$9.50h, $(9.50h +2.20rh)

Step-by-step explanation:

Every hour ----- $9.50

h hours ----- h ×$9.50

Amount of money Mr Smith earns in h hours

= $9.50h

If he fixes a watch per hour, additional income= $2.20h

If he fixes r watches per hour, additional income= $2.20rh

Total income

= $(9.50h +2.20rh)

What are the x-intercepts of the graph of the quadratic function

Svetllana [295]

Zero Product Property: if a × b = 0, then either a or b = 0 or both a and b = 0.

(Make sure to set f(x) to zero)

So for this equation, I will be factoring by grouping. Firstly, what two terms have a product of -5x^2 and a sum of 4x? That would be 5x and -x. Replace 4x with 5x - x: $0=5x^2+5x-x-1$

Next, factor 5x^2 + 5x and -x - 1 separately. Make sure that they have the same quantity on the inside: $0=5x(x+1)-1(x+1)$

Now you can rewrite the equation as: $0=(5x-1)(x+1)$

Now apply zero product property to the factors to solve for x:

$5x-1=0\\5x=1\\x=\frac{1}{5}\\\\x+1=0\\x=-1$

<u>The x-intercepts are (1/5 ,0) and (-1,0).</u>

Answer:

$\boxed{4 \sqrt[8]{ {d}^{3} } }$

Step-by-step explanation:

$= > 4 {d}^{ \frac{3}{8} } \\ \\ = > 4({d}^{3 \times \frac{1}{8} }) \\ \\ = > 4( {d}^{3} \times {d}^{ \frac{1}{8} } ) \\ \\ = > 4( {d}^{3} \times \sqrt[8]{d} ) \\ \\ = > 4 \sqrt[8]{ {d}^{3} }$

svet-max [94.6K]

Answer:

75.5 cm

Step-by-step explanation:

S = (a+b)*h/2
