Answer:

Below in bold.

Step-by-step explanation:

c) 3 x (9^2)^3/4 x ((81^3)^5/6

= 3 x 81^3/4 x 81^15/6

= 3 x 81^(3/4 + 15/6)

= 3 x 81^13/4

= 3 x 3^13

= 3^14

= 4,782,969.

f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2

=  5^-2 x^2y^-4 / 625 x^4y^-2

=  5^-2 x^-2 y^-2 / 5^4

= 5^-6 x^-2y^-2

= 0.000064x^-2y^-2.

Can someone help me?
bixtya [17]

Answer:

y = 2.1x +5, 21 miles

Step-by-step explanation:

We will denote miles as "x"

Since she tipped the driver $5, that is a flat rate and that will be our y-intercept. Since it costs $2.10 per mile, we need to multiply that number by the number of miles

So our equation will be y = 2.1x +5

In order to figure out how many miles Ann lives from the airport, we need to substitute y for her grand total that she was charged

This gives us 49.10 = 2.10x + 5

First we need to subtract 5 from each side to get 44.10 = 2.10x

We then need to divide both sides by 2.10 to get 21 = x

Ann drove 21 miles

Cooper bought a serving platter originally priced at $20 but on sale for 50% off. After 10% sales tax, what was the total cost?
Gelneren [198K]

Answ

$11.00

Step-by-step explanation:

A quick way to do this would be as follows:  1.10 ( 0.50*$20), or $11.00.


0.50($20) gives us the sale price (at half off); that's half of $20, or $10.

The total due is then $10 (item cost) plus $1 (tax), or $11

2. The bottom of a ramp is placed 15 feet from the edge of a stage
Firdavs [7]

Answer:

The slope of the ramp is 1.

Step-by-step explanation:

See the diagram attached.

Here, AC  = 15 ft. and ED = 5 ft. while AE = 10 ft.

Then, EC = (15 - 10) = 5 ft.

Now, considering the right triangle Δ EDC, if \theta is the inclination of the ramp, then \tan \theta = \frac{ED}{EC} = \frac{5}{5} = 1

Hence, \theta = 45 ^{\circ}

Therefore, the slope of the ramp is 1. (Answer)
