Answer:

see below

Step-by-step explanation:

are the rational numbers a subset of all real numbers?

yes of course

by definition the real numbers is the union of the rational numbers and the irrational numbers

so we can say that the rational numbers are a subset

and every rational number is part of the real number

are the rational numbers a subset of the irrational numbers?

the rationals numbers are all those numbers that you can write as p/q with q different of 0, and the irrationals numbers are those that you cannot write as a fraction

so as you can see those are two completely different types of number, to be a subset every rational number must be in the irrationals , and by the definition we know it can't happen

Carson took a total of 24 quizzes over the course of 4 weeks. How many weeks of school will Carson have to attend this quarter b

erastovalidia [21]

Answer:

9 weeks

Step-by-step explanation:

Assuming he takes equal number of quizzes weekly then having taken 24 quizzes within 4 weeks means for every week Carson took 24/4=6 quizzes per week.

With a target of 54 quizzes this quater and while maintaining 6 quizzes per week then Carson will take 54/6= 9 weeks to meet thw target.

Therefore, Carson needs 9 weeks this quater

A petrol can is a rectangular prism with base measurements 15 cm by 30 cm. If the can has capacity 18 liters, find its height.

Bingel [31]

Answer:

Step-by-step explanation:

The first step is to calculate the base area of the prism

= 15×30

= 450

The volume is then calculated as follows

= 450×h

= 450h

The capacity is 18 liters

= 18×1000

= 18,000

Therefore the height of the rectangular prism can be calculated as follows

450h= 18,000

h= 18,000/450

= 40

Hence the height is 40 cm

A circle is a shape formed by a curved side. Therefore, the required answers are:

1. An example of an inscribed angle is: <SQT or <QST or <QTS

2. An example of a minor arc is: arc QT or RS or QR

3. An example of a semicircle is: QRS or QTS

4. <QPR = $\frac{264600}{44r}$ degrees

An angle is said to be formed whenever two or more straight lines intersect or meet. But an inscribed angle is an angle formed within a given circle.

A circle is a shape formed by a curved side. Some of its parts are semicircle, radius, diameter, chord, sector, segment, etc.

Thus the following can be deduced from the given question:

1. An example of an inscribed angle is: <SQT or <QST or <QTS

2. An example of a minor arc is: arc QT or RS or QR

3. An example of a semicircle is: QRS or QTS

4. <QPR.

length of an arc = $\frac{x}{360}$ 2 $\pi$ r

where r is the radius of the circle

105 = $\frac{x}{360}$ x 2 x $\frac{22}{7}$ x r

= $\frac{44xr}{2520}$

44 xr = 105 x 2520

44xr = 264600

x = $\frac{264600}{44r}$

Therefore the measure of angle QPR in terms of r is $\frac{264600}{44r}$ degrees.

5. The length of arc QTR can be determined by;

Arc QTR = $\frac{x}{360}$ 2 $\pi$ r
