Answer:

[tex]\frac{4x^{21}}{y^{11}}[/tex]

Step-by-step explanation:

You are going to need to know two properties of exponents.  

[tex]x^a * x^b = x^{a+b}\\\frac{x^a}{x^b}=x^{a-b}[/tex]

Also know that a*b = b*a, so youc an change the order of multiplication.  

Since everything is being multiplied in the numerator, and there is only multiplication, it's actually super easy to start.  Just multiply everything.

[tex]8x^9y^8(-2)x^5y^{-9} = -16x^{14}y^{-1}[/tex]

so now you have [tex]\frac{-16x^14y^{-1}}{-4x^{-7}y^6}[/tex]

Again, since the numerator and denominator only have multiplication you can divide part by part.  so the number divides the number, the x term divides the  term and the y term divides the y term

-16/-4 = 4

x^14 / x^-7 = x^21

y^-1 / y^6 = y^-7

So all together that makes[tex]4x^{21}y^{-7}[/tex]

The final step in simplifying is making all negative powers into fractions.  Sometimes non whole numbers can be made into roots.  Definitely make negative powers fractions though

[tex]\frac{4x^{21}}{y^{-7}}[/tex]

Answer:

[tex]P" = (-1,7)[/tex]

Step-by-step explanation:

Given

[tex]Point - (-7,5)[/tex]

90 degrees clockwise rotation

6 points left translation

Required

The new point

Apply the first transformation

90 degrees clockwise transformation

When a point P (x,y) is rotated in the clockwise direction by 90 degrees, the new point is: P' (y, -x)

So:

[tex]P = (-7,5)[/tex] becomes

[tex]P' = (5,7)[/tex]

Apply the second transformation

6 points left translation

To do this, we simply subtract 6 from the x coordinate

[tex]P' = (5,7)[/tex] becomes

[tex]P" = (5-6,7)[/tex]

[tex]P" = (-1,7)[/tex]

Answer:

=537.6 acres

Step-by-step explanation:

1 acre = 43560 ft^2

5280ft = 1 mile

Area of the farm

0.6miles×1.2miles = 3168ft×6336ft

=23,417,856ft^2

=23,417,856÷43560

=537.6 acres

Jimmy stopped in Yewton for 45 minutes if Jimmy cycled at a steady speed of 24 km/h and his average speed for the whole journey, including the stops, was 18 km/h.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that:

At 12:45 Jimmy left his home in Pinetrees and cycled to visit his grandmother in Oakville.

Let x be the total time Jimmy stops in Yewton:

Total time for the journey = 220 minutes (12:45 to 16:25)

As we know:

distance = speed×time

24(220 - 10 - x) = 18(220)

220 - 10 - x = 165

x = 210 - 165

x = 45 minutes

Thus, Jimmy stop in Yewton for 45 minutes if Jimmy cycled at a steady speed of 24 km/h and his average speed for the whole journey, including the stops, was 18 km/h.

Answer:

Yup ur answer is 20.5 ounces

Step-by-step explanation:

since there's an additional 2.25 ounces every second I multiplied 2.25 by 4

2.25•4=9

9 ounces added to the beginning 11.5 ounces equals 20.5 ounces that are now in the bowl

Answer:

hi, the answer is b

Step-by-step explanation:

i dont know how to explain it but good luck!

<3

Answer:

I really only know second one

So for team a the median is 4

the upper is 5 and the lower is 2

the highest is 8 lowestis 0

The median for b is 8

upper is 9 lower is 6

lowest is 0 highest is 10

It can't be a because they don't have the same median. Team A DOES have a lower median. It is not C. I really am thinking B

Answer:

php 1500

24 pesos

Step-by-step explanation:

Purchase price = 7500

Amount sold = 9000

The markup will be :

Amount sold - purchase price

9000 - 7500

= php 1500

2.)

Price = 80 pesos

Markup rate % = 30

The Markup = 30% * 80

Markup = 0.3 * 80

Markup = 24 pesos

Answer:

  $14.14

Step-by-step explanation:

The amount of interest earned is ...

  I = P((1 +r/365)^n -1) . . . . interest on principal P at annual rate r compounded daily for n days

  I = 3021(1 +0.055/365)^31 -1) ≈ 14.14

$14.14 in interest is earned in 31 days.

5        3         15

6/15 can be simplified to 2/5.

the answer is y=21

Step-by-step explanation:

hope this helps:)

Answer:

y=21

Step-by-step explanation:

92 = 5y - 13

92 + 13 = 5y - 13 + 13

105 = 5y

105/5 = 5y/5

21 = y
