Step-by-step explanation:

Take the composite figure, with the base, made up of the rectangle with dimensions 4 in x 6 in and the triangle with base of 6 in and height of 4 in, and the height of the figure is 6 in.

Find the volume:

Answer:

12) v=0

13) w=9

14) y=5

15) z=-8

16) n=2, m=-2

17) x=3

18) 1, because \(2^{4}/{2^{4} =1\). Therefore \(2^{4}/{2^{4} = 2^{4-4}=2^{0}=1\)

Step-by-step explanation:

12) Exponent Zero rule. Anything raise to 0 power equals 1.

13) Exponent Negative rule: \(b^{-n} =\frac{1}{b^n}\)

14) Exponent Quotient rule: \((a^n/a^m)=a^{n-m}\)

In this case, \((3^3/3^5)=3^{3-5}=3^{-2}=1/3^2=1/9\)

15) Exponent Product rule: \((a^n*a^m)=a^{n+m}\)

In this case, \((5^8*5^{-8})=5^{8-8}=5^0=1\)

16) Same rule as #15, \((7^2*7^{-2})=7^{2-2}=7^0=1\)

17)We can work backwards here, we know \(2^{2} = 4\) and \(3^{1} =3\), so we need \(2^2/3^1=4/3\).

To achieve this, use Exponent Quotient rule, what x-4=1? x=5.

Similar base: \((3^5/3^4)=3^{5-4}=3^{1}=1/3\). Put \(2^{2}\) back for \(\frac{4}{3}\)

18) 1*1*1*1=1. Anything raise to 0 power equals 1 (Exponent Zero rule). To prove this, any number(except 0) divided by itself equals 1.

Ex: 1/1=1, 4/4=1, \(2^4/2^4=1\).

We can prove this with the Exponent Quotient rule. \(1=\frac{3}{3} =\frac{3^1}{3^1}=3^{1-1}=3^0=1\). No matter how I write it, it's equal to 1.

The one exception is \(0^{0}\), which is undefined, since dividing by zero is illegal.

Hope this helps. ;)

The product of the exponents is 1.7325 x 10⁻².

Given data:

To find the product of 1.65 and 1.05 × 10⁻², multiply the two numbers:

A = 1.65 × 1.05 × 10⁻²

From the laws of exponents:

mᵃ×mᵇ = mᵃ⁺ᵇ

First, multiply the decimal numbers:

1.65 × 1.05 = 1.7325

Next, multiply the result by 10⁻², which is equivalent to moving the decimal point two places to the left:

1.7325 × 10⁻² = 0.017325

Hence, the product of 1.65 and 1.05 × 10⁻² is 0.017325.

Answer:

x is -12

Step-by-step explanation:

\(\rightarrow \frac{-1}{4}x-12-x=x+3-x\\\\\rightarrow \frac{-1}{4}\cdot x-x-12=x+3-x\\\\\rightarrow \frac{-1}{4}+\frac{-4}{4}x-12=x+3-x\\\\\rightarrow \frac{-1-4}{4}\cdot x-12=x+3-x\\\\\rightarrow \frac{-5}{4}\cdot x-12=x+3-x\\\\\rightarrow \frac{-5}{4}\cdot x-12=x-x+3\\\\\frac{-5}{4}\cdot x-12=3\)

Step 2

\(\rightarrow \frac{-5}{4}\cdot x-12=3\\\\\rightarrow \frac{-5}{4}x-12+12=3+12\\\\\rightarrow \frac{-5}{4}\cdot x=3+12\\\\ \frac{-5}{4}\cdot x=15\)

Step 3

\(\rightarrow \frac{-5}{4}\cdot x=15\\\\\rightarrow \frac{-5}{4}x\cdot \frac{4}{-5}=15\cdot \frac{4}{-5}\\\\\rightarrow \frac{-5}{4}\cdot x\cdot \frac{-4}{5}=15\cdot \frac{4}{-5}\\\\\rightarrow \frac{-5}{4}\cdot \frac{-4}{5}x=15\cdot \frac{4}{-5}\\\\\rightarrow 1x=15\cdot \frac{4}{-5}\\\\\rightarrow x=15\cdot \frac{4}{-5}\\\\\rightarrow x=15\cdot \frac{-4}{5}\\\\\rightarrow x=\frac{15\cdot -4}{5}\\\\x=-12\)

Answer:

answer is 3/5

Step-by-step explanation:

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Step-by-step explanation:

Answer:

x^5(1+x)(1-x+x^2)

Step-by-step explanation:

b^5 +b^8 =

You can easily solve this equation by doing factoring (a fancy word for dividing)

so, factor out the Greatest Common Factor (GCF)

which is

B^5

so in parenthesis write (1+b^3) next to it, think of subtracting the two exponents, and then since theres only 1 thing left after factoring out b^5, you leave a 1 behind.

b^5(1+b^3)

from here, in the parenthesis, you have 2 perfect cubes, 1 and b^3

take the cube root of that which is (1+b)

then use (a+b) which is already done

AND (a^2-ab+b^2) where a is equal to 1, and b is equal to variable b.

so, that would be

x^5(1+x)(1-1x+x^2) ( this is what you should get once you do multiply the square root out to just get constants and coefficients.

That gives us our final answer of x^5(1+x)(1-1x+x^2) because it is in the simplest form possible.
