Answer:

Arc length = 29.33 unit (Approx)

Step-by-step explanation:

Given:

Radius of length r = 8

θ = 210°

Find:

Arc length

Computation:

Arc length = [θ/360]2πr

Arc length = [210/360]2(22/7)(8)

Arc length = 29.33 unit (Approx)

Answer:

9x ≥ 81

Step-by-step explanation:

Given

Total = $81 (atleast)

Required

Represent as an inequality

Let the number of weeks he x

If he saves $9 in a week, then he will save $9x in weeks

From the question we understand that he needs at least $81

At least, in inequality means ≥

So, the inequality is:.

9x ≥ 81

x-5=4 or simply 4+5

Step-by-step explanation:

Im not sure if this is how you mean they both have a way of showing the sum of 4 and 5.

Answer:

4 + 4 + 1 = 9

Step-by-step explanation:

to solve this, we first find the sum of 4 and 5, which is 9.

Then, we can observe our answer choices, and see that option 4.) would be correct, because the sum still is equal to nine, even though the numbers are different from the original problem.

Answer:

x = 30

Step-by-step explanation:

well the two agnles are congruent so they have to equal the same angle

x+ 90 = 4x

solve for x bye subtracting x from 90

90 = 3x slove by dividing 90 by 3 getting x alone

90/3 = x

Answer:

After 300 minutes of long distance calls it will be cheaper  for a customer to purchase the first plan.

Step-by-step explanation:

With the information provided, you have to find the amount of minutes of long distance calls where it will be cheaper for the customer to purchase the first plan by stating that the price of the second plan which is calculated by adding up the fixed fee plus the result of multiplying the price per minute for the number of minutes is higher than the price of the first plan, which could be express as:

10+0.05x>25, where:

x is the number of minutes

Now, you can solve for x:

0.05x>25-10

0.05x>15

x>15/0.05

x>300

According to this, the answer is that after 300 minutes of long distance calls it will be cheaper  for a customer to purchase the first plan.

Answer:

13 vehicles

Step-by-step explanation:

Just solve 20% of 65. "Of" means to multiply, and 20% is just 0.2

So, you would do:

0.2 × 65 = 13 vehicles

Answer and explanation:

The inequality theorem states that the sum of the length of two sides of a triangle is greater than the third side of a triangle.

Also the difference of two sides of a triangle is less than the third side

If we apply this theorem here,

Then we say the third side x<20+25 and x>25-20

Therefore x<45 but >5

5<x<45

Possible sides of x include: 6,7,8,9,10,11,12,13,14,15,16,17,18...not equal to 45 or more than

The answer to this is yes

Answer:  21

Why: 21/2321

Using the concept of a confidence interval, it is that the margin of error in this example is of 2%.

------------------------

A confidence interval for a percentage is written in the following format:

[tex]P \pm M[/tex]

That is, the percentage is of P, plus of minus M points, in which M is the margin of error.

Answer:

7 sheets

Step-by-step explanation:

Dimension of gabble = 42' by 5'

Dimension of standard plywood sheet : 4' by 8'

Area that will be covered by gabble :

Length * width :

42 * 5 = 210 in²

Area covered by 1 plywood sheet :

4 * 8 = 32 in²

Number of plywood sheets required :

Area of gabble / Area of 1 plywood sheet

210 in² / 32 in²

= 6.5625

This means the number of plywood sheets that will be required is 7

Answer:

Step-by-step explanation:

From the picture attached,

∠4 = 45°, ∠5 = 135° and ∠10 = ∠11

Part A

∠1 = ∠4 = 45°  [Vertically opposite angles]

∠1 + ∠3 = 180° [Linear pair of angles]

∠3 = 180° - ∠1

     = 180° - 45°

     = 135°

∠2 = ∠3 = 135°  [Vertically opposite angles]

∠8 = ∠5 = 135° [Vertically opposite angles]

∠5 + ∠6 = 180° [Linear pair of angles]

∠6 = 180° - 135°

∠6 = 45°

∠7 = ∠6 = 45° [Vertically opposite angles]

By triangle sum theorem,

m∠4 + m∠7 + m∠10 = 180°

45° + 45° + m∠10 = 180°

m∠10 = 180° - 90°

m∠10 = 90°

m∠10 = m∠12 = 90°  [Vertically opposite angles]

m∠10 = m∠11 = 90° [Given]

Part B

1). ∠1 ≅ ∠4  [Vertically opposite angles]

2). ∠7 + ∠5 = 180° [Linear pair]

3). ∠9 + ∠10 = 180° [Linear pair]

Answer:

5 black counters

Step-by-step explanation:

1/3 to sixths would equal two sixths. The problem already told us three of the siths, meaning the 15 are the other three sixths. Since 3/6 are half of the bag, then multiply 15 by two. Since there are 30 in all, and the bags are in thirds, you devide by three. Since 10 is the 1/3, you divide by 2 (10 by 2) since you multiply 1/3 to get the equivalant of 2/6. There are 5 black ones.

You could've also had done 30 divided by 6 to get 5 which is still the 1/6 of the bag.

The subtract  x² + 3x y -y²   from x² + 5xy

                  x² + 5xy - ( x² + 3x y -y²)

          ⇒     x² + 5xy -x² - 3xy +y²
