What is the simplified form of the cube root of x squared times the third root of x squared

Answer:

x\sqrt[3]{x}

Step-by-step explanation:

\sqrt[3]{x^2} *\sqrt[3]{x^2}

Both terms have same cube root so we multiply the terms and put it inside the cube root

Apply exponential property

a^m * a^n = a^{m+n}

x^2* x^2 = x^4

\sqrt[3]{x^2} *\sqrt[3]{x^2}=\sqrt[3]{x^4}

\sqrt[3]{x^4}=\sqrt[3]{x^3*x^1}=x\sqrt[3]{x}

HELP PLEASE!! Determine whether the statement is true or false then EXPLAIN: Line Plots display individual data.

TRUE. I'm going to be using a picture from Google to help me out. In the graph below the line plots are telling how much Sarah's is as the years past. Each line plot tell the data of how much her car cost in whatever year the plot is in. For example, in 2006 her car cost $10,000. How do we know? We know this because the line plot is point towards 10,000 and downwards to 2006. This is data that the line plots are displaying fro us.So yes, line plots do display individual data.
Hope this helps!!! :) Pls mark me BRAINLIEST!

A school principal ordered 1000 pencils he gave an equal number to each of seven teachers until he had given out as many as possible how many pencils were left

If you have 1000 pencils and you divide by 7 teachers, you would have 142 pencils divided evenly. Then you would take the 142 pencils and multiply by 7 which will give you a total of 994 pencils that went to the teachers in total. So the remaining pencils would be 1000 minus 994 and the total left over will be 6 pencils. I hope this helps.

What is the simplified form of the cube root of x squared times the third root of x squared

The cubic root of x, by itself, would simply be 1/3 x. but, when you have an exponent in the radicand as an unknown, it gets more complicated. first, you have to solve what is inside the radicand first, following order of operations. so, first you solve x squared. x is your unknown, so you would need to determine the value of x and then square it. after that, you cube your answer. if we place 2 as x, for an example, you would find 2 squared to be 4, then cube that for your answer.

Which calculation should be completed first to solve this story problem? Allister bought some sheet music. He bought 6 songs for $0.99 each and 1 book for $16.99. He paid $1.38 in sales tax. He gave the cashier $50. How much change should Allister get? A. total cost of all the purchases B. total cost of 6 songs C. sum of the cost of 1 song, the book, and the tax D. the change

A. total cost of all the purchases

You can't calculate the sales tax on the sheet music or the change for $50 he would have received (which requires subtracting the total cost from $50) until you know how much the sheet music cost total.

 The B) and C) options aren't  relevant to the problem. You're trying to find the amount of change he gets after paying the total cost for all the sheet music + the tax on that.

Hey there!

If the total amount of times Mark recorded the color of the traffic light is 15, then the number of red lights he recorded would be 15 minus the amount of green and yellow lights. 

15 – 6 – 2 = 7

There was a total of 7 red lights recorded by Mark.

Identify as a direct variation, inverse variation or neither. Is the total cost to fill a car gas tank a direct or inverse variation with respect to the number of gallons used?

Answer:

It  is a case of a direct variation.

Step-by-step explanation:

Direct variation--

Two variables x and y are said to be in direct variation if there exist a constant k such that:

y=kx

i.e. with the increase/decrease in one variable the other variable also increases/decreases.

Inverse variation--

Two variables x and y are said to be in inverse variation if there exist a constant k such that:

xy=k

i.e. with the increase in one variable the other decreases and vice-versa.

Here the independent variable is: Number of gallons used.

and the dependent variable is: Total cost to fill a car gas tank.

As we know that as the number of gallons used increases the total cost also increases and it increases by some constant k.

Since, the cost of per gallons is some fixed.

Line segment WX is the radius of circle X, and line segment ZY is the radius of circle Y. Points W, X, C, Y, and Z are all on line segment WZ. What is the area of circle C, which passes though points W and Z? 81 164 324 1296

Point D is the midpoint of the outer circle that we aim to find the area of

The circle has a diameter of WZ and radii of WC and CZ

We know that YZ=YD=10 cm

Let DC be x and CY be 10-x

The radius of the outer circle can be written as 8+8+x or 10+10-x which we can equate to find the value of x

8+8+x=10+10-x
16+x=20-x
2x=4
x=2

Therefore, the radius of the circle is 8+8+2=18

And hence the area of the circle is   \pi (18^{2})=324 \pi

QUESTION POSTED AT 17/10/2019 - 09:06 AM

Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 3:35 to 3:55? (Hint: Find the number of degrees per minute first.) Part 2: How far does the tip of the minute hand travel during that time?

Part1

there are 360° in a circle (clock), and thus if we check how many degrees in a clock with 60minutes, then it'd be 360/60, or 6° per minute

now, the clock went from 3:35 to 3:55, 20 minutes, how many degree is that? 6*20

part2

\bf \textit{length of an arc}\\\\
s=\cfrac{r\theta\pi }{180}\qquad 
\begin{cases}
r=radius\\
\theta=\textit{angle in degrees}\\
----------\\
r=4\\
\theta=6\cdot 20
\end{cases}\implies s=\cfrac{4\cdot 6\cdot 20\cdot \pi }{180}
