1. An airplane flies with a constant speed of 560 miles per hour. How far can it travel in 4 hours?
2. Sarah rides her bike with a constant speed of 12 miles per hour. How far can she travel in
3 1/2 hours?
Answers
Answer:2240 miles. 42 miles
Step-by-step explanation:
This is so easy. For the first question you know that for each hour the plane goes 560 miles. All you have to do is times four with 560 and you get 2240 miles. Likewise, for each hour she rides her bike 12 miles. Using the same logic I times 12 with 3.5 and I got 42 miles.

For problems 5 – 8, find the perimeter of the following figures. (3 points each)
Answers
Answer:
5. 132.8 m
6. 5 7/16 in
7. 5 37/63 yd
8. 27.376 m.
Step-by-step explanation:
5) To find the perimeter of a rectangle, add up all of the sides.
Remember, in a rectangle, opposite sides are congruent.
\(17.1 + 49.3 + 17.1 + 49.3 \\= 132.8\)
The perimeter is 132.8 m.
-----------------------------------------------------------------------
6) To find the perimeter of a pentagon, simply add up all of the sides.
\(1\frac{1}{8} +1\frac{1}{8} +1\frac{1}{16} +1\frac{1}{16} +1\frac{1}{16} \\\\= 5 \frac{7}{16}\)
The perimeter is 5 7/16 in.
-----------------------------------------------------------------------
7) To find the perimeter of a circle, use this formula: π × d OR π × r × r
π = 22/7
r = 1 1/3
Since we know what each variable equals, we plug it into the formula, then solve from there.
π × r × r ➜ 22/7 × 1 1/3 × 1 1/3 = 5 37/63.
The perimeter is 5 37/63.
-----------------------------------------------------------------------
8) To find the perimeter of a circle, use this formula: π × d OR π × r × r
π = 3.14
d = 8.4
Since we know what each variable equals, we plug it into the formula, then solve from there.
π × d ➜ 3.14 × 8.4
= 26.376
The perimeter is 26.376 m.

7. Integers are always rational numbers.
Answers
Answers: statements 1, 2, 6 and 7
=======================================================
Explanation:
I'll briefly go through each statement to mention why it's true or false.
This one is a bit tricky. Some math books define the natural numbers to be N = {1, 2, 3, ...} where 0 isn't included, while other textbooks include 0. The inclusion/exclusion of zero seems arbitrary and depends on other context of the math theorems used. The set of whole numbers is more consistent and it is W = {0, 1, 2, 3, ...} basically it's the definition of natural numbers where 0 is included. So if 0 is defined to be a natural number in your textbook, then statement 1 is true. Otherwise, it's false.This is true. A rational number like 2/3 isn't a whole number, but something like 3/1 = 3 is a whole number. Any whole number can be written as itself over 1.This is false. An integer like -7 is not in the set of natural numbers.This is false. The very definition of "irrational" means "not rational". The two types of numbers are complete opposites. An irrational number is one where we cannot write it as a ratio of integers. A famous example is pi = 3.14... as we can't write it as a fraction of integers. An approximation could be something like 22/7, but we don't capture the full picture of what pi really is.This is false. Refer to question 4 above. The set of rational numbers vs irrational numbers do not overlap at all.This is true. Refer to questions 4 and 5. This is true. We can write any integer as itself over 1. For example, the integer -12 is the same as -12/1 to show that it is rational. This idea is similar to what I mentioned in question 2.After going through all seven statements, we definitely know that statements 2, 6, 7 are true. Statements 3,4,5 are definitely false.
Statement 1 is the only thing left. If your teacher mentioned 4 true statements, then statement 1 has to be true. This in turn means that your teacher is defining 0 to be a natural number.

Inverse operations are the opposite equation, and used to "undo" the equation in a sense.
For example, let's take addition and subtraction.
3+4 is 7.
To "undo" the equation, we must use the inverse operation, which is subtraction.
We can do 7-3, which is 4, or 7-4, which is 3.
This can be applied to other operations.
Vicente and Carla each ran 8 laps around a track. They started at the same time and place. If Vicente ran 1.5 times as fast as Carla, how many laps did Carla have left to finish when Vicente finished his 8th lap?
Answers
Answer:
4
Step-by-step explanation:
She is going half the speed as him, so she will have four laps left.
The distance left in 8 laps for Carla when Vicente has already finished his 8th lap is 2 2/3 laps.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance Covered / Time taken
Let the distance of a single lap be x units. Also, the time it takes for Carla to complete a single round is represented by y.
Speed of Carla = x/t
Speed of Vicente = 1.5(x/t)
Now, the time it will take Vincente to complete the 8 laps is,
Time = 8x / [1.5(x/t)]
Time = 8tx / 1.5x
Time = 16t/3
Distance covered by Carla by the time Vincente completed 8 laps,
Distance = Speed × Time
= (x/t) × (16t/3)
= 16x / 3
Now, the distance left in 8 laps is,
Distance left in 8 laps = Total distance - Distance covered
= 8x - (16x/3)
= (24x - 16x)/3
= 8x / 3
= 2 2/3 x
= 2 2/3 laps
Hence, the distance left in 8 laps for Carla when Vicente has already finished his 8th lap is 2 2/3 laps.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
