34

Answer:

yes sir burrito

Step-by-step explanation:

Given:

The equation is

[tex](-a-b)x=3a+3b[/tex]

To find:

The value of x.

Solution:

We have,

[tex](-a-b)x=3a+3b[/tex]

It can be written as

[tex]x=\dfrac{3a+3b}{(-a-b)}[/tex]

[tex]x=\dfrac{3(a+b)}{-(a+b)}[/tex]

Cancel out the common factors.

[tex]x=\dfrac{3}{-1}[/tex]

[tex]x=-3[/tex]

Therefore, the value of x is -3.

Answer:

The answer is 65

Step-by-step explanation:

3-2 = 1

4^3 = 64

64+1 = 65

Hope this helps.

Answer:

[tex]65[/tex]

Step-by-step explanation:

Firstly, you have to Simplify what's inside the parentheses.

and that is 3-2 = 1.

[tex] {4}^{3} + 1[/tex]

Secondly, you have to Simplify 4³ to 64. 4 to the power of 3 is 64.

[tex]64 + 1[/tex]

And lastly, you have to simplify 64 + 1. which is.

[tex]65[/tex]

Therefor, the answer is, 65.

Answer:

1. g. $0.10 per square inch

2. b. $0.08 per square inch

3. f. $10

4. m. $8

5. h. 79 in²

6. j. 113 in²

Step-by-step explanation:

1. A = πr²

  r = diameter ÷ 2 = 10 ÷ 2 = 5

  A = π(5)² = 25π in² ≈ 78.53981

  $8.00/25π = $0.10 per square inch

2. A = πr²

  r = diameter ÷ 2 = 12 ÷ 2 = 6

  A = π(6)² = 36π in² ≈ 113.0973355

  $10.00/36π = 0.088419 = $0.09 per square inch

3. information/answer was provided

4. information/answer was provided

5. A = πr²

  r = diameter ÷ 2 = 10 ÷ 2 = 5

  A = π(5)² = 25π in² ≈ 79 in²

6. A = πr²

  r = diameter ÷ 2 = 12 ÷ 2 = 6

  A = π(6)² = 36π in² ≈ 113 in²

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is [tex](\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )[/tex]

So, let [tex](x_{2} , y_{2} )[/tex] be the coordinates of the endpoint you are looking for.

[tex]x_{1} = -9[/tex]  and [tex]y_{1} = 7[/tex]

[tex](\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )[/tex] = (10, -3)

[tex]\frac{-9 + x_{2} }{2} = 10[/tex]           [tex]\frac{7 + y_{2} }{2} = -3[/tex]

-9 + [tex]x_{2}[/tex] = 20         7 + [tex]y_{2} = -6[/tex]

[tex]x_{2} = 29[/tex]                    [tex]y_{2} = -13[/tex]

endpoint is (29, -13)

Answer:

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

[tex] \frac{130}{260} = \frac{1}{2} [/tex]

The fraction of the boys of Year 11 is 1/2.

Fractions are used to represent smaller pieces (or parts) of a whole.

Given that, there are total 260 students of 11 years in which 130 are girls and 130 are boys.

The fraction of boys of 11 years = 130/260 = 1/2

Therefore, half of the strength of students are boys.

Hence, The fraction of the boys of Year 11 is 1/2.

the answer is 0.0800320128 or in simplified form 0.08

Step-by-step explanation:

First you divide 12 ÷ 5.88 = 2.04081632653. Then you divide 20 ÷ 10.20 = 1.96078431373. Lastly you subtract 2.04081632653 - 1.96078431373 =  0.0800320128 or 0.08

Answer:

440

Step-by-step explanation:

330 divided by 3 times 4 is 440 and thats your answer.

====================================================

Work Shown:

330 pages = 3/4 hour

4*(330 pages) = 4*(3/4 hour)  ........ multiply both sides by 4

1320 pages = 3 hours

1320/3 pages = 3/3 hours ...... divide both sides by 3

440 pages = 1 hour

Ethan's rate is 440 pages per hour.
