Which expression is equivalent to 15a^9b^4 over 5a^5b?

1 answer:

3 0

If you would like to solve 15a^9b^4 / 5a^5b, you can calculate this using the following steps:

15a^9b^4 / 5a^5b = 3a^(9-5)b^(4-1) = 3a^4b^3

The correct result would be D. 3a^4b^3.

Volume of a cylinder is defined as:

v = volume

r = radius

h = height.

V = $\pi$ (r^2)h

In this problem,

v = 1,356.48 in^3

r = 6 in

h = ?

Plug our numbers into the volume formula above.

1,356.48 in^3 = $\pi$ (6^2)h

Divide both sides by $\pi$ (6^2) to isolate variable h

12.0 = h

The height of the cylinder is 12.0 inches

liubo4ka [24]

1. 2.96 = 2 96/100 = 2 24/25 ( thats 2 and 24/25)
2. 1 out of 2 = 1/2 (Erin)
6 out of 8 = 3/4 (Lauren)
Lauren is more successful because 3/4 is greater then 1/2

5(3r+11)=85

raketka [301]

Answer:

r = 2

Step-by-step explanation:

Actually, there are 2 ways to solve this equation.

The first one:

5( 3r + 11) = 85

so here, you have to multiply 5 by ( 3r + 11) and maintain the 85

15r + 55 = 85... now put the like terms together. In other words, just transpose 55 to the other side. 

15r = 85 -55..... remember that the sign of 55 will change from positive to negative 

15r = 30.... now divide both sides by 15

15r/15 = 30/15

 r = 2

The second method :

5 ( 3r + 11) = 85...... divide both sides by 5

5 (3r + 11) / 5 = 85/5

3r + 11 = 17

3 r = 17 - 11

3r = 6 

r = 2

I hope this helps. If you don't quite get it, please go through until you get it. Have a nice day :-)

Michael's dad is 30 years of age. He is 2 years more than four times Michaels age m. Write and solve a two-step equation to dete

Ksenya-84 [330]

Answer:

The two step equation that we can use to find michael's age is x = (f-2)/4 where f = 30. So Michael is 7 years old.

Step-by-step explanation:

In order to solve this problem we will attribute variables to the ages of Michael and his father. For his father age we will attribute a variable called "f" and for Michael's age we will attribute a variable called "x". The first information that the problem gives us is that Michael's dad is 30 years of age, so we have:

f = 30

Then the problem states that the age of the father is 2 years "more" than four "times" Michaels age. The "more" implies a sum and the "times" implies a product, so we have:

f = 2 + 4*x

We can now find Michael's age, for that we need to isolate the "x" variable. We have:

f - 2 = 4*x

4*x = f - 2

x = (f-2)/4

x = (30 - 2)/4 = 7 years

The two step equation that we can use to find michael's age is x = (f-2)/4 where f = 30. So Michael is 7 years old.

1. Determine whether the regular hexagon has reflection symmetry, rotation symmetry, both, or neither. If it has reflection symm

lana [24]

The regular hexagon has both reflection symmetry and rotation symmetry.

Reflection symmetry is present when a figure has one or more lines of symmetry. A regular hexagon has 6 lines of symmetry. It has a 6-fold rotation axis.

Rotation symmetry is present when a figure can be rotated (less than 360°) and still look the same as before it was rotated. The center of rotation is a point a figure is rotated around such that the rotation symmetry holds. A regular hexagon can be rotated 6 times at an angle of 60°
