Answer 1

Answer:

x = 3

Step-by-step explanation:

Applying Pythagoras' identity to the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + x² = ($\sqrt{18}$ )², that is

2x² = 18 ( divide both sides by 2 )

x² = 9 ( take the square root of both sides )

x = $\sqrt{9}$ = 3

what in the 6 grade math ?

Answer:

It's the green one, and the percentage is 2/5 (40%)

Step-by-step explanation:

Explanation: There were 600 total tickets sold, 240 of them being for the Saturday performance. The question is asking what percent of the total tickets sold were for the Saturday performance, so you do 240/600 which is 2/5 (0.40, 40%). As for the diagram, you kinda just figure out which one has the "?" 2/5ths along the way of the diagram. Hope this helps for your question, and explain the problem for future reference.

Answers

Answer:

Step-by-step explanation:

$3 - ( - \frac{8}{2} )$

$( - \frac{8}{2} ) = - 4$

$3 - ( - 4)$

$3 + 4 = 7$

Answer: It should be 7

Step-by-step explanation:

Step 1 of 2: Subtract.

Subtract

3 − (negative 8 over 2 −

) = 14 over 2

Step 1 of 2: Subtract, sub-step a: Convert integer to a fraction.

Convert integer to a fraction

3 = 3 over 1

Step 1 of 2: Subtract, sub-step b: Subtract a negative.

Subtract a negative

3 over 1

− (negative 8 over 2 −

) = 3 over 1

+ 8 over 2

Subtracting a negative is the same as adding a positive.

Step 1 of 2: Subtract, sub-step c: Find common denominator.

Find common denominator

3 over 1

+ 8 over 2

= ( 3 × 2 ) over ( 1 × 2 )

3 × 2

1 × 2

+ ( 8 × 1 ) over ( 2 × 1 )

8 × 1

2 × 1

= 6 over 2

+ 8 over 2

2 is the least common multiple of denominators 1 and 2. Use it to convert to equivalent fractions with this common denominator.

Step 1 of 2: Subtract, sub-step d: Add.

Add

6 over 2

+ 8 over 2

= ( 6 + 8 ) over 2

6 + 8

= 14 over 2

Step 1 of 2: Subtract.

Step 2 of 2: Simplify.

Simplify

14 over 2

= 7

What is 11x to the second power minus 3 x times y to the third power if x = 3 and y = 2?

Answers

Answer:

Step-by-step explanation:

$11x^{2} -3x*y^3$

Now we replace the variables by the numbers given.

$11(3)^2-3(3)*2^3$

We use PEMDAS, (parentheses, exponents, multiplication, division, addition, subtraction)

First we solve the exponents.

$11(9) - 3(3) * 8$

Next the multiplication, left to right

$99-9*8$

$99-72$

$27$

Joseph earns $1070 monthly. Of that, $160.50 is withheld for taxes. What percent of Joseph's earnings is withheld?

Answers

Answer:

15%

Step-by-step explanation:

Percentages are just division.

The percentage of Joseph's earnings withheld for taxes = money spent on taxes/money earned

Percentage = 160.50 / 1070

Percentage = 0.15 = 15%

0.15 = 15% because to get percentages from decimals, you multiply the decimal by 100

Therfore, 15% of Joseph's money is withheld for taxes.

I hope this helps!

Answers

Answer:

Step-by-step explanation:

you are completely right please follow your heart <3

It’s actually D.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.
