Answer:

x = 6

Step-by-step explanation:

20x + 11 + 9x - 5 = 180 ( linear pair)

29x + 6 = 180

29x = 180-6

29x = 174

x = 6

hence angles are:

20(6) + 11 = 131

9(6) - 5 = 49

Answer:

Solution,

Step-by-step explanation:

20x+11+9x-5=180° (being linear pair)

or, 29x+6=180

or, 29x=180-6

or, 29x=174

or, x=174 ÷29

Therefore x=6°

The Highest Common Factor (HCF) of 18, 36 and 120 is 6.

A factor is a number that divides another number, leaving no remainder.

Given that, we need to find HCF of 18, 36 and 120.

Finding Factors :-

18 = 2 × 3 × 3

36 = 2 × 2 × 3 × 3

120 = 2 × 2 × 2 × 3 × 5

Common factors = 2 and 3

Therefore,

Highest Common Factor = 2 × 3 = 6

Hence, the Highest Common Factor (HCF) of 18, 36 and 120 is 6.

Step-by-step explanation:

Look at the right triangle formed. You are given the Hypotenuse and an adjacent side to the angle needed to calculate the measure of the arc.

To find measure of angle use Cosine

Once you find measure of angle (central angle), you'll have the measure of the arc because they are the same.

Step-by-step explanation:

Formula for the volume of a cylinder= V=πr²h

8 = radius

15 = height

V=64π x 15

V = 3015.99cm³ (rounded to 2DP)

Answer:

3014.4 cm^3

Step-by-step explanation:

volume of a cylinder =

[tex]\pi \: r {}^{2} h[/tex]

h = 15

r = 8

pi = 3.14

volume = 3.14 × 8^2 × 15

A sample is a group of persons or items collected or selected from a statistical population. The sample is 1127 households that owned a television.

A sample is a group of persons or items collected or selected from a statistical population by a predetermined approach in statistics and quantitative research methods. Sample points, sampling units, and observations are terms used to describe the components of a sample.

We know that sample is a group of people selected from the population, since there are 1565 state households, while there are 1127 households that owned television and who are surveyed. Therefore, the sample is 1127 households that owned a television.

Answer:

  1/3

Step-by-step explanation:

The simulation will say that Jeffrey collected three different toys if the numbers in a group of three are either 0 or 1, a number more than 1 and less than 6, and a number 6 or more.

The groups {3, 7, 1}, {5, 1, 7}, {9, 2, 0}, {3, 0, 6} and {4, 6, 0} all simulate collection of all three toys from three boxes of cereal. Of the 15 simulated sets of three boxes, that is a probability of 5/15, or 1/3.

_____

Additional comment

The simulated toy numbers can be grouped in different ways. For example, we could take a vertical column of numbers as representing the purchase of 3 boxes of cereal. Doing that, we find 3 different toys only for the simulated values {4, 0, 6}, the last digits in the 4th column. The probability from considering the simulation that way is 1/15.

From this group of 45 numbers, one could calculate P(car) = 10/45, P(bus) = 19/45, and P(airplane) = 16/45. These vary a little from the theoretical values. Overall, with these values, the probability of 3 different toys from 3 boxes is about 0.200, only slightly different from the theoretical probability of 0.192.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Multiply the top equation by 3.

3*(x - y)/3 = 0.5 * 3

(x - y) = 1.5

There is no single solution that satisfies this system. There infinitely many values for x and y that will work. The only restriction is that x - y = 1,5

So if you make y = 3

x - 3 = 1.5                   Add 3 to both results

x - 3 + 3 = 1.5 + 3       Combine

x = 4.5

Infinitely many solutions exist.

Answer:

Two angles whose sum is 90° (that is, one right angle) are called complementary angles and one is called the complement of the other.

Here, ∠AOB = 40° and ∠BOC = 50°

Therefore, ∠AOB + ∠BOC = 90°

Here, ∠AOB and ∠BOC are called complementary angles.

∠AOB is complement of ∠BOC and ∠BOC is complement of ∠AOB.

Step-by-step explanation:

remember the definitions of these 2 types of numbers ?

rational numbers are all numbers that can be written as

a/b

where a and b are integers, and b <> 0.

this includes all real fractions, but also all whole or integer numbers, as they can be written as a/1.

if they have digits after the decimal point, they are either finite, or they have a repeating pattern for all eternity.

irrational numbers are all numbers with an infinite series of digits after the decimal point without any repeating patterns.

that includes all squares roots of non-squared numbers or any other roots of numbers that are not the product of correspondingly many multiplications with themselves. and trigonometric function and logarithm results, and the special numbers in math and physics : pi and e.

so,

4/7 is rational

sqrt(30) is irrational

21/sqrt(4) is a trick question, as sqrt(4) = 2.

so, this is actually

21/2 is rational

pi is irrational

Answer:

83 degrees

Step-by-step explanation:

The angles 56 and 41 plus the one in between should add up to 180 degrees. So you do 180 - 56 - 41 = 83.

83 and x are vertical angles so they are the same measure.

<x = 83 degrees

Step-by-step explanation:

The total bill is the subtotal plus tax. The tax is computed by multiplying the tax rate by the subtotal, which is the total of all items being billed.

  subtotal = $5.25 +12.75 +2.99 = 20.99

  tax = $20.99 × 0.09 = $1.89

The total bill is ...
