Answer:
[tex]47x^3\sqrt{5x}[/tex]
Step-by-step explanation:
The objective is to combine the terms to make one radical, so therefore we know that we will have to take a [tex]\sqrt{5}[/tex] out of the second radical [tex]\sqrt{180}[/tex].
If we divide 180 by 5, we will get 36, so now we have
[tex]\sqrt{180}=\sqrt{5}[/tex]×[tex]\sqrt{36}[/tex]
[tex]\sqrt{36}[/tex] can be simplied into just 6.
So now the expression becomes
[tex]-\sqrt{5x^7}+8x^2*6 \sqrt{5x^3}[/tex]
Then we can further simplify by moving the [tex]x^{2}[/tex] into the radical to get two common terms with [tex]\sqrt{5x^7}[/tex].
[tex]x^{2} =\sqrt{x^4}[/tex], so we now have
[tex]-\sqrt{5x^7}+ 8\sqrt{x^4} *6 \sqrt{5x^3}[/tex]
So then we can combine the two radicals to get the expression to
[tex]-\sqrt{5x^7}+48\sqrt{5x^7}[/tex]
We now see that we have two terms with a common radical, and coefficients of -1, and 48.
That allows us to simplify further to
[tex]47\sqrt{5x^7}[/tex]
Here, we can take out [tex]\sqrt{x^6}[/tex], which is [tex]x^3[/tex], and get the final simplied form to be
[tex]47x^3\sqrt{5x}[/tex]

A random sample of internet subscribers from the west coast of the United States was asked if they were
satisfied with their internet speeds. A separate random sample of adults from the east coast was asked the same
question. Here are the results:
A market researcher wants to perform a x2 test of homogeneity on these results.
What is the expected count for the cell corresponding to east coast subscibers who
responded "yes"?
You may round your answer to the nearest hundredth.
Answers
Answer:
19.2
Step-by-step explanation:
khan
The expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We need to first calculate the expected frequencies for each cell under the assumption that the null hypothesis of homogeneity is true.
The null hypothesis of homogeneity assumes that the proportion of internet subscribers satisfied with their internet speeds is the same on both the east and west coasts of the United States.
To calculate the expected frequencies, we can use the formula:
Expected frequency = (row total x column total) / grand total
For the cell corresponding to east coast subscribers who responded "yes":
Expected frequency = (row total for east coast x column total for "yes") / grand total
= (80 x 48) / 200
= 19.2
Therefore, the expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

What is the area of this figure? 5 in 6 in 15 in 16 in 10 in 20 in
Answers
Answer:
230 in.²
Step-by-step explanation:
20 · 10 = 200 in.²
5 · 6 = 30 in.²
200 in.² + 30 in.²
Answer:
230 sq in
Step-by-step explanation:
You can find entire area (20 x 16) and subtract out the area of the missing piece (15 x 6)
20 x 16 = 320
15 x 6 = 90
320 - 90 = 230
There is just enough water in the container to exactly fill the

height of the water in the cone. Round to the nearest tenth.
Answers
Answer: hello your question is Vague hence I will provide a general solution. in which you can input your values into and get your answer.
answer = h = 3 ( V / π r^2 )
Step-by-step explanation:
The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .
The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )
∴ h = 3 ( V / π r^2 )
Closest to the shaded area
Answers
Answer:
B) 30.9
Step-by-step explanation:
So, because the radius is 6, we know the diameter is 12, meaning we know each side is 12, so the total area of the square is 144.
To find the area of a square we should use pi(r) ^2 which is pi(6) ^2 which is 113.09. to find the area of the shaded are we would subtract these. 144- 113.09 this gets us 30.91, this is closest to B) 30.9

I believe it would 18 ounces of chips for 3 cups of flour. If you take half of 12 ounces then you get 6 ounces per cup of flour. Adding 6 ounces to the 12 would get us the total of the 18 ounces.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answers
Answer:
V = 3,367.6 cm³
Step-by-step explanation:
Diameter of sphere (D) = 18.6 cm
radius (r) = ½(18.6) = 9.3
π = 3.14
Formula for volume of a sphere = ⁴/3πr³
Plug in the values
V = ⁴/3 × 3.14 × 9.3³
V = ⁴/3 × 3.14 × 804.357
V = (4*3.14*804.357)/3
V = 3,367.57463
V = 3,367.6 cm³ (nearest tenth)

the diameter is a circle is 16in. Find it’s circumference in terms of π.
C= ________in
Answers
According to the question,
Diameter of circle = 16 inWe are asked to calculate it’s circumference in terms of π.
★ Circumference of circle = 2πr
___________________________________
Let us first calculate the radius of the circle.
→ Diameter = 2 × Radius
→ 16 in = 2r
→ r = 16 in ÷ 2
→ r = 8 in
___________________________________
Substituting values in the formula of circumference,
→ C = 2πr
→ C = (2 × π × 8) in
→ C = 16π in
Therefore, 16π inches is the required answer.
