What is the following product? Sqr5x^8y^2 sqr10x^3 sqr12y

PSYCHO15rus [73]

Step-by-step explanation:

$\sqrt{5 {x}^{8} {y}^{2} } \times \sqrt{10 {x}^{3} } \times \sqrt{12y} \\ \\ = {x}^{4} y \sqrt{5} \times x \sqrt{10x} \times 2 \sqrt{3y} \\ \\ = 2 {x}^{5} y \sqrt{5 \times 10x \times 3y} \\ \\ = 2 {x}^{5} y \sqrt{5 \times 5 \times 2x \times 3y} \\ \\ = 2 {x}^{5} y \times 5\sqrt{ 2x \times 3y} \\ \\ = 10 {x}^{5} y \sqrt{6xy} \\$

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon lef

Nastasia [14]

Answer:

Orange ribbon Zoe use is $1\frac{3}{4} \ feet.$

Step-by-step explanation:

Given:

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon left.

Now, to find the orange ribbon Zoe use.

Let the orange ribbon Zoe use be $x.$

Total orange ribbon Zoe had = $3\frac{1}{8} = \frac{25}{8} \ feet.$

Ribbon Zoe had left = $1\frac{3}{8} =\frac{11}{8} \ feet.$

Now, to get the orange ribbon Zoe use:

$\frac{25}{8} -x=\frac{11}{8}$

<em>Subtracting both sides by </em> $\frac{11}{8}$ <em> we get:</em>

$\frac{25}{8} -x-\frac{11}{8} =0$

<em>Adding both sides by </em> $x$ <em> we get:</em>

$\frac{25}{8} -\frac{11}{8} =x$

$\frac{25-11}{8} =x$

$\frac{14}{8}=x$

$x=\frac{14}{8}$

$x=\frac{7}{4}$

$x=1\frac{3}{4}\ feet.$

Therefore, orange ribbon Zoe use is $1\frac{3}{4} \ feet.$

The score on a trivia game is obtained by subtracting the number of incorrect answer from twice the number of correct answer. If

brilliants [131]

Answer:

The player answer correctly 30 questions

Step-by-step explanation:

First we have to develop the information that gives us as 2 equations

x = correct answer

y = incorrect answer

z = score = 40

h = total answer = 50

2x - y = z x + y = h

2x - y = 40 x + y = 50

we clear the x of one equation and replace the value of x in the other equation

x = 50 - y

2x - y = 40

2(50 - y) - y = 40

100 - 2y - y = 40

-3y = 40 -100

y = -60/-3

y = 20

x = 50 - y

x = 50 - 20

x = 30

Tegan needs to make 686868 more snow blocks to finish building an igloo. Write an equation for the number of blocks Tegan still

Keith_Richards [23]

Answer:

We are given:

No: of blocks Tegan still needs to make = m.

No: of blocks Tegan has completed = c

Total No:of more snow blocks need to make = 68 .

Total number of more snow blocks need to make = Total number of blocks - The number of blocks Tegan has completed.

m = 68 - c.

Therefore, the equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks is

m = 68 - c.

For example.

Suppose if c = 10, it means Tegan still needs to make 68-10 = 58 block.
