The prism is partially filled with 150 cubic cm of sand what fraction of the prism is filled by the sand

Since 150 can't go into 250 twice as a whole, you know that the percentage is over 50% . To find the percentage (I think, bad memory) You need to find the difference or increase between the two. 250 / 150 = 100 Then divide the increase or difference by the original number (As in 150) then multiply that by 100. The percentage would be 66% 

Hope this helps, though would ask someone again just to be sure

You mix the letters M, A, T, H, E, M, A, T, I, C, A, and L thoroughly. Without looking, you draw one letter. Find the probability P(A). Write the probability as:a. a fraction in simplest form b. a decimal c. a percent

There are total 12 letters. 3 from them are the letter A.
The probability that the drawn letter is A can be calculated:
P(A)=number of events "letter A occurs"/ number of possible events that may occur 
P(A)=3/12
a. as a fraction: 3/12=1/4
b. as a decimal: 0.25
c. as a percent: 25%

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}

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.

Simplify the expression. 10P8

Answer:

10P8= 1,814,400

Step-by-step explanation:

Given: 10P8

It is a permutation.

We have formula to find the permutation.

nPr = \frac{n!}{(n-r)!}

Here n = 10 and r = 8

Now plug in the given values in the above formula, we get

10P8 = \frac{10!}{(10 - 8)!}

= 10!/2!          [n! = 1*2*3*4...n]

= 10*9*8*7*6*5*4*3*2*1 / 1*2

Cancelling out 1 and 2 both in the numerator and the denominator, we get

= 10*9*8*7*6*5*4*3

10P8= 1,814,400

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. y = x2 − 2x − 19 y + 4x = 5 The pair of points representing the solution set of this system of equations is (-6, 29) and .

Solution:

The two equation given which are in two variables are

1. y = x²-2 x -1 9

2. y + 4 x=5

Writing equation 2 as→y = 5 -4 x

Substituting the value of y in equation 1

⇒ 5 - 4 x = x² - 2 x - 19

⇒x² - 2 x + 4 x -19 -5=0

⇒ x² + 2 x -24=0

⇒x² + 6 x - 4 x - 24=0→→→[Breaking the middle term i.e term containing x]

⇒ x(x+6) -4(x+6)=0

⇒(x-4)(x+6)=0

⇒x-4=0 ∧ x+6=0

⇒x = 4     ∧    x= -6

Put x=4 in equation 2,

y + 4 ×4=5

y + 16=5

y = 5-16

y= -11

As one solution is (-6, 29), The other solution of the system of equation is (4, -11).

Simplify the rational expression state Any excluded values

Before you start realize that division by zero is undefined.  So x cannot equal 6 as 6-6=0.  With that noted, you can factor the numerator which is a difference of squares of the form (a^2-b^2) which always factors to (a+b)(a-b).  In this case the difference of squares is (x^2-36) so it is equal to (x+6)(x-6) so you have:

[(x+6)(x-6)]/(6-x)  now you can factor out -1 from the second term in the numerator to get:

[-1(x+6)(6-x)]/(6-x)  so the (6-x)s cancel out leaving:

-1(x+6) which is equal to

-x-6 which is the simplified form of the original equation.

So the answer is D. as -x-6 and x cannot equal 6.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? m – = 2 + m

This is the concept of algebra, to solve the expression we proceed as follow;
m-=2+m
this can be written as:
-m=2+m
-m-m=2
-2m=2
multiply both sides by -1/2
-1/2(-2m)=2*(-1/2)
m=-1
the answer will therefore be m=-1

Say x = 0.77--
Then 10x = 7.7--
Then 10x - x = 7 => 9x=7 => x=7/9

Say x = 2.3-
10x = 23.3-
10x-x = 9x = 21 => x = 21/9

last one is a bit tougher because it has alternating digits

Say x = 1.013--
100x = 101.313--
100x-x = 99x = 100.3 = x = 1003/990

I multiplied the final fraction with 10 to get integers.

Point A and B lie on a circle with a radius of 1, and arc AB has a length pi/3. What fraction of the circumference of the circle is the length of arc AB?

First we need to find the circumference of the circle with the formula C=2*r*π, where r is the radius and it is r=1. So C=2*1*π=2π. The arc AB has a length of π/3. To find the fraction of the circumference the arc has we just divide the length of the arc AB with the circumference C:
AB/C=(π/3)/(2π)=π/(6π)=1/6. So the length of the arc AB is 1/6 of the circumference C.
