Answer:

The average speed is 36.67 m/h

Step-by-step explanation:

100/50 = 2

120/30 = 4

Total time = 6

Total distance = 220 miles

220/6 = 36.67

Kia thinks that every number has at least two factors. Which explains whether Kia is correct?
elena-14-01-66 [18.8K]

Solution:

Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.

The number zero has infinite factors.

The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.

Prime integers  has only two factors one and itself.

Non prime integers has more than two factors.

But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.

So, yes Kia is not absolutely true, but if she has written the statement in this form:  Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.

Answer:

m∠RPQ = 8°

Step-by-step explanation:

m∠QRS = 4x - 15

m∠RPQ = x + 1

m∠PQR = x - 2

m∠QRS is exterior angle and m∠RPQ and m∠PQr are opposite interior angles to m∠QRS

m∠QRS = m∠RPQ + m∠PQR      {Exterior angle property of triangle}

4x - 15 = x +1 + x - 2

4x - 15 = x + x + 1-2          {Combine like terms}

4x - 15 = 2x - 1        {Subtract 2x from both sides}

4x - 2x - 15 = - 1

2x - 15 = - 1                  {Add 15 to both sides}

2x = -1 + 15

2x = 14          {Divide both sides by 2}

x = 14/2

x = 7

m∠RPQ = x + 1 = 7 + 1 = 8°

Since 6 is a y point, you substitute it for y in slope intercept form.
same goes for x.

dem82 [27]

Bruce will receive $160 million for the batmobile.

<h3>What is percentage?</h3>

The term "percentage" comes from the Latin phrase "per centum," meaning means "by the hundred." Percentages is fractions with a denominator of 100.

In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.

Calculating a percentage implies determining a portion of a whole in term of 100. A percentage can be calculated in two ways:

  1. The unitary technique is used.
  2. By adjusting the fraction's denominator to 100.
  3. It must be noted that second method of percentage calculation is not employed when the denominator isn't a factor of 100. In such circumstances, we employ the unitary technique.

Now, according to the question;

Given that prices fall about 20% every decade;

Thus,  100% - 20% = 80%

He paid $250 million for a batmobile twenty years ago.

Let Bruce to receive x millions of dollars for the batmobile.

⇒ 80% of x = 80/100 × x = 4/5 x

⇒ x = 250(4/5)(4/5)

⇒ x = 250(16/25)

⇒ x = 160

As a result, Bruce will receive 160 millions of dollars for such batmobile.

The correct question is-

Twenty years ago, Bruce Wayne bought a batmobile for 250 million dollars. As the crime in Gotham city

has been down for a while, he plans to sell it.
