The set of all **numbers **on a number line is called the "**Real Numbers**".

Any **number **that can be represented as the **ratio **of two **integers **and where the **denominator **is not zero is referred to as **rational**.

The **set **of all **numbers** on a **number **line is called the "**Real Numbers**".

A **number **that has an **equivalent terminating **or repeating **decimal **is called a "**Rational Number**".

A **number **that has an **equivalent** **decimal** that is non-repeating is called an "**Irrational Number**".

Any **number **that can be **written **as a **fraction **of **integers **is a "**Rational Number**".

Hence, the **set **of all **numbers** on a **number **line is called the "**Real Numbers**".

Question

The drawing is composed of a rectangle and a semicircle 18 cm 22 cm

Solution 1

What do you need?

The perimeter is L + w + L + perimeter of a semicircle.

L = 22 cm

W = 18 cm

Perimeter can be one of two answers. You need to specify where the semicircle is.Â Formula for semicircle is

pi * r

r = 18/2 = 9 or

r = 22/2 = 11

So the perimeter of the semi circle is pi * 9 = 25.12 The total Perimeter = 22 + 22 + 18 + 25.12 = 87.12

It can also be 22 + 18 + 22 + 34.54 = 96.54 There are even more possiblities for perimeter. I would have the same problem if you asked about area.

Why not put more details in and I'l give you the correct answer. Here is what we need to know

1. Where is the circle on the 22 cm side or the 18 cm side?

2. What are you looking for: perimeter or area? As soon as you answer these I'll be back.

Question

What are the variables and coefficients on the problem 5.4 times 2 + 2.8 times 2

Solution 1

So remember that variables are variable or in other words they can changeÂ like x

coeficients are things that yo uknow like 2,5,3/5

so since all of them are numbers, allÂ of them are coeficients

coeficients are things that yo uknow like 2,5,3/5

so since all of them are numbers, allÂ of them are coeficients

Question

What is the height of a building in meters if it takes a rock 3.8 seconds to drop from its roof

Solution 1

height = 70.756 m

x = ut + 0.5atÂ²

where:

x is the distance that we want to calculate

u is the initial velocity of the body = 0 (assuming the body starts from rest)

a is the acceleration due to gravity = 9.8 m/secÂ²

t is the time taken = 3.8 seconds

x = ut + 0.5atÂ²

x = 0(3.8) + 0.5(9.8)(3.8)Â²

x = 70.756 m

Hope this helps :)

Question

arnold calculated his mean score after three rounds of golf.he noticed that his score in the first round was 3 strokes below the mean and his score in the second round was 1 stroke below the mean if Arnoldâ€™s mean score was 72 what was his score in the third round

Solution 1

Mean = 72

First round = 72-3 = 69

Second round = 72-1 = 71

Third round = 76

Explanation:

Total score = 72*3 = 216

69+71+x = 216

140+x = 216

x = 76

First round = 72-3 = 69

Second round = 72-1 = 71

Third round = 76

Explanation:

Total score = 72*3 = 216

69+71+x = 216

140+x = 216

x = 76

Question

Question

Terry ate 1/4 of a giant cookie. Cami and Rene each ate 1/2 of what was left over l. What fraction of the cookie did Cami eat? Please explain!

Solution 1

3/8. After terry, 3/4 was left and half of 3/4 is 3/8

Solution 2

Cami ate 3/8 of the cookie.

Question

HELP ASAP!! The graph shows one of the linear equations for a system of equations. Which equation represents the second linear equation for the system of equations that has the solution which corresponds to a point at (2, 0)?
A) -x - 3y = 2
B) x + 3y = -2
C) 5x + y/2 = 10
D) 5x + y/2 = -10

Question

A random sample (Sample 1) of the cars' average driving speed (km/h) is: 120, 132, 142, 119, 112, 130, 149, 111, 167, 139, 141. A random sample (Sample 2) of the SUVs' average driving speed (km/h) is: 112, 135, 124, 115, 119, 90, 112, 134, 113, 114, 115. What is the median of Sample 1? What is the median of Sample 2?

Solution 1

Sample 1 is 132

sample 2 is 115

sample 2 is 115

Question

QUESTION 1: A prism has a surface area of 100 in2. Which sentence describes the effect of measuring the surface area in square feet? A. The surface area stays the same, but the number representing the surface area decreases.
B. The surface area increases.
C. The surface area stays the same, but the number representing the surface area increases.
D. The surface area decreases.
QUESTION 2: A prism has a surface area of 100 cm2. Which sentence describes the effect of measuring the surface area in square millimeters?
A. The surface area stays the same, but the number representing the surface area increases.
B. The surface area decreases.
C. The surface area stays the same, but the number representing the surface area decreases.
D. The surface area increases.

Solution 1

The answer is **A** in both cases. Changing the units does not change the measurement, only the number representing the measurement. (Some numbers are easier to work with than others, which is why some units are preferred for certain measurements.)

Question 1.

**Â Â A.Â ****The surface area stays the same, but the number representing the surface area decreases.**

Question 2.

**Â Â ****A. The surface area stays the same, but the number representing the surface area increases.**

Question 1.

Question 2.

Solution 2

**Answer:**

A

**Step-by-step explanation:**

A. The surface area stays the same, but the number representing the surface area increases.
