Answer:

20x^8y^{10}

Step-by-step explanation:

\frac{4x^{-2}y^2}{2^{-3}x^2y^7}*(x^{-4}y^{-5})^{-3}-12x^8y^{10}

you have to cancel the fraction stuff, distribute the exponent in the second term multiply, simplify like terms and then subtract the last term

it would take a very long time for me to explain all this and type it out so instead copy and paste this into mathpapa.com and it will explain it

\frac{4x^{-2}y^2}{2^{-3}x^2y^7}*(x^{-4}y^{-5})^{-3}-12x^8y^{10}

then let me know if you have any questions in the comments and I will answer

Hope this helps! :)

Find the measure of the indicated side or angle.
lozanna [386]

Answer:

60°

Step-by-step explanation:

We'll begin by calculating EC. This can be obtained as follow:

Angle EAC = 39°

Hypothenus = EA = 3.7 m

Opposite = EC =?

Sine EAC = Opposite /Hypothenus

Sine 39 = EC / 3.7

Cross multiply

EC = 3.7 × Sine 39

EC = 2.3 m

Finally, we shall determine angle BEC. This can be obtained as follow:

Adjacent = EC = 2.3 m

Hypothenus = BC = 4.6 m

Angle BEC =?

Cos BEC = Adjacent / Hypothenus

Cos BEC = 2.3 / 4.6

Cos BEC = 0.5

Take the inverse of Cos

BEC = Cos¯¹ 0.5

BEC = 60°

Thus, angle BEC is 60°

A right circular cylinder has a height of ​ 19 3/4 ​ ft and a diameter ​ 1 2\5 ​ times its height.
alexira [117]

Answer:

Volume of cylinder is  34833.21 ft³

Step-by-step explanation:

Given : A right circular cylinder having height 19\frac{3}{4} ft and diameter \frac{12}{5} ​times its height.

Given : diameter \frac{12}{5} ​times its height that is

diameter \frac{12}{5} ​times  19\frac{3}{4}  that is

Diameter = \frac{12}{5} \times \frac{79}{4} ​

Diameter = \frac{237}{5} ft

Radius is half of diameter,

Radius = \frac{1}{2} \times \frac{237}{5}=\frac{237}{10} ft

\text{Volume of Cylinder}=\pi r^2h

Substitute the values, we get,

\text{Volume of Cylinder}= \pi (\frac{237}{10})^2 \times \frac{79}{4}

\text{Volume of Cylinder}= \times 3.14 \times (23.7)^2 \times 19.75

\text{Volume of Cylinder}= \times 3.14 \times (23.7)^2 \times 19.75

\text{Volume of Cylinder}=34833.21

Thus, volume of cylinder is  34833.21 ft³

Please need help with #1 it is so confusing
vfiekz [6]

Answer: circle 2 and 5

Step-by-step explanation:

The problem is asking which number can 428 by divided by evenly.

Step 1: 428 divided by 2 is 214 Since it was evenly divided, you circle 2. It is the same for 4.

Step2: Keeping dividing each of the numbers to see if 428 can by divided by the number. If the answer comes out as a decimal number than don’t circle.

Jenny was in charge of selling tickets to a family fun night at her school
ra1l [238]
I’ve attached my work below for #4
5) 8% is equivalent to 8 cents so each item was $1.08
Than you know he spent 16.20 so you divided
1.08/16.20 which equals 15
So he got 15 items
6) the moon is 250,000 miles away which is about driving around earth 10 times which would take 6 months (not sure about this one)

Hope this helps!
Have a nice day :)
