Insert two rational numbers between-1/3 and 2/3. with explanation with whole process
Answer:
Two rational numbers between -1/3 and 2/3 are:
0 and 1/3
Step-by-step explanation:
A rational number is a number that can be written as the quotient of two integer numbers.
Here, we want to find two rational numbers that are between:
-1/3 and 2/3
So, our numbers need to be larger than -1/3 and smaller than 2/3
This is ratter simple, let's start with the lower limit (-1/3) let's add a rational number to it.
Then check, the new number meets the conditions? if not, then we try adding a smaller rational number and so on.
Just because in both cases we have a denominator 3, i will add numbers that also have a denominator of 3.
First try:
Let's try adding 1/3
-1/3 + 1/3 = 0
the number 0 is a rational number: 0 = 0/1
and is true that:
-1/3 < 0 < 2/3
So we already found one of the rational numbers.
Now let's try again, let's add 5/3 this time
-1/3 + 5/3 = (-1 + 5)/3 = 4/3
This is larger than 2/3, so this is not in the desired range.
Let's try again, this time adding 2/3
-1/3 + 2/3 = (-1 + 2)/3 = 1/3
is true that:
-1/3 < 1/3 < 2/3
So the number 1/3 is in the desired range, so we found the second rational number.
You can see that this is kinda a trial and error way to solve these problems, this is the "easier" way to start, as you work with this, eventually you will practice enough and will be easy to find numbers between given ranges.
Jason wants to earn at least $250 each week working during the summer.
Jason earns $6.00 an hour babysitting.
Jason earns $7.75 an hour working at a store.
He can work no more than 40 hours each week.
Let b equal hours of babysitting, and s equal hours working at the store.
Which system of inequalities models the constraints?
6.00b + 7.75s ≤ 40
b + s ≥ 250
6.00b + 7.75s ≥ 250
b + s ≤ 40
6.00b + 7.75s ≥ 40
b + s ≥ 250
6.00b + 7.75s ≤ 250
b + s ≤ 40
Answer:
6.00b + 7.75s ≥ 250
b + s ≤ 40
Step-by-step explanation:
6.00b + 7.75s ≥ 250---this represents how much he will make
b + s ≤ 40---these are his hours. B+S are his hours, and they can't be greater than 40 hrs, so ≤.
Which of the following is a reciprocal of 3/9?
Answer:
It would be 3.
Step-by-step explanation:
So, a reciprocal is basically just flipping over the numerator and the denominator of a fraction. Therefore:
3/9 ---> 9/3
The reciprocal of the fraction number in the simplified form will be 3.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The fraction number is given below.
⇒ 3 / 9
Simplify the fraction number, then we have
⇒ 3 / 9
⇒ 1 / 3
The reciprocal of the fraction number will be given as,
⇒ 1 / (1/3)
⇒ 3
The reciprocal of the fraction number in the simplified form will be 3.

B

с
28.8 in.
D
14.4 in.
Answer:
D. 14.4
Step-by-step explanation:
In similar polygons, corresponding sides are proportional. We can write the proportion:
[tex]\frac{l-A}{l-B} =\frac{w-A}{w-B}[/tex]
l-A is the length of A, l-B is the length of B, w-A is the width of A, and w-B is the width of B. We are given the ratio of the lengths is 2:5, so we can substitute it in:
[tex]\frac{2}{5} =\frac{w-A}{36}[/tex]
We can cross multiply:
72 = 5w-A
w-A = 14.4

4+2y<18 help please
Answer: 2
Step-by-step explanation:
We don't know what is the Y.
Then, 4 + 2y < 18 is:
6y < 18
If y=2, it'll make this equation true.
6*2 < 18
12 < 18.
So, Y=2

Terry needs to carry a pole that
is 10 feet tall through a
rectangular doorway that
measures 6 feet by q feet. Will
the pole fit diagonally through the
doorway? Explain.
6 ft
9 ft
Answer:
Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole.
Step-by-step explanation:
Using the Pythagorean Theorem, ([tex]a^2+b^2=c^2[/tex] ) we can measure the hypotenuse of a right triangle. Since the doorway is a rectangle, and a rectangle cut diagonally is a right triangle, we can use Pythagorean Theorem to measure the diagonal width of the doorway.
Plug in the values of the length and width of the door for a and b. The c value will represent the diagonal width of the doorway:
[tex]6^2+9^2=c^2[/tex]
[tex]36+81=c^2[/tex]
[tex]117=c^2[/tex]
Since 117 is equal to the value of c multiplied by c, we must find the square root of 117 to find the value of c.
[tex]\sqrt{117} =10.8[/tex]
[tex]10.8=c[/tex]
Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole, measuring 10 feet.

A radio station plays a total of 272 pop, rock, and hip-hop songs during a day. The number of pop songs is 3 times the number of rock songs. The number of hip-hop songs is 32 more than the number of rock songs. Write a system of THREE linear equations to represent this situation.
Answer:
x + y + z = 272 - - - - - - (1)
x = 3y - - - - - - - - - - - - - (2)
z = 32 + y - - - - - - - - - - (3)
Step-by-step explanation:
Let :
Number of pop songs = x
Number of rock songs = y
Number of hophops = z
Sum of the three types of songs = 272
x + y + z = 272 - - - - - - (1)
Pop is 3 times Rock :
x = 3y - - - - - - - - - - - - - (2)
Hiphop is 31 more than rock
z = 32 + y - - - - - - - - - - (3)
(b) Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.
Answer:
√18 = 3√2
Step-by-step explanation:
the square root of 18 = √18
18;
1 × 18 = 18
2 × 9 = 18
3 × 6 = 18
6 × 3 = 18
9 × 2 = 18
18 × 1 = 18
9 has a perfect square
So,
√18 = √(2*9)
= √2 * √9
= 3√2
√18 = 3√2
Perfect square
1 × 1 = 1
2 × 2 = 4
3 × 3 = 9
4 × 4 = 16
5 × 5 = 25
Therefore,
√18 is between 4 and 5
