3^4 × h^5 × g^2 / 3^2 × h^8 Could you show me the steps so I can understand easier?

hoa [83]

Answer:

$\dfrac{3^{2} \times g^{2}}{h^{3} }$

Step-by-step explanation:

We have to simplify the following mathematical expression.

The expression is $\dfrac{3^{4} \times h^{5} \times g^{2}}{3^{2} \times h^{8} }$

Now, $\dfrac{3^{4} \times h^{5} \times g^{2}}{3^{2} \times h^{8} }$

= $3^{(4 - 2)} \times h^{(5 - 8)} \times g^{2}$

{Since, all the terms are in product form, so, we can treat them separately}

{We know the formula of exponent $\dfrac{x^{a} }{x^{b} } = x^{(a - b)}$ }

= $3^{2} \times h^{- 3} \times g^{2}$

= $\dfrac{3^{2} \times g^{2}}{h^{3} }$ (Answer)

{Since, we know, $x^{- a} = \dfrac{1}{x^{a}}$ }

Is trapezoid ABDC the result of a dilation of trapezoid MNPQ by a scale factor of Two-fifths? Why or why not? Yes, because AB an

IgorC [24]

Answer:

No, because AB is 2/5 the length MN but CD is 1/3 the length QP.

Step-by-step explanation:

Comparing the corresponding sides, the length of AB is 4. The length of MN is 10. This makes their ratio 4/10 = 2/5.

The length of CD is 2. The length of QP is 6. this makes their ratio 2/6 = 1/3.

The ratios of the sides are not the same, so the figure is not proportional and is therefore not a dilation.

Two payment options to rent a car: You can pay $20 a day plus 25¢ a mile (Option A) or pay $10 a day plus 50¢ a mile (Option B).

BaLLatris [955]

You must drive more than 40 miles to make option A the cheaper plan

Solution:

Two payment options to rent a car

Let "x" be the number of miles driven in one day

You can pay $20 a day plus 25¢ a mile (Option A)

25 cents is equal to 0.25 dollars

OPTION A : 20 + 0.25x

You pay $10 a day plus 50¢ a mile (Option B)

50 cents equal to 0.50 dollars

Option B: 10 + 0.50x

For what amount of daily miles will option A be the cheaper plan ?

For option A to be cheaper, Option A must be less than option B

Option A < Option B

$20 + 0.25x < 10 + 0.50x$

Solve the inequality

Add -0.50x on both sides

$20 +0.25x -0.50x < 10 + 0.50x - 0.50x\\\\20 - 0.25x < 10$

Add - 20 on both sides,

$20 - 0.25x - 20 < 10 - 20\\\\-0.25x < -10$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}$

$0.25x > 10$

Divide both sides by 0.25

$x > 40$

Thus you must drive more than 40 miles to make option A the cheaper plan
