Answer:
(a)
Five rational numbers between -1 and 1 are:-
:: -9/10, -8/10, -7/10, -6/10,-5/10
(b)
Five rational numbers between 4/3 and 3/2 are:-
:: 81/60, 82/60, 83/60, 84/60, 85/60
Explanation:-
If we have to find rational numbers we have to multiply both the numerator and denominator by same number
eg:- 5,10,20. In case you do not find five or ten rational numbers you have to again multiply the numerator and denominator by the same number.
The hourly rates of a supermarket's employees are shown below. Find the median. Please show your work and include a label on your answer.
$9.25, $8.50, $22.50, $7.85, $8.85, $12.65, $10.85, $11.50
Answer: Median = the number in the middle of a set of data
So first we order the data:
7.85, 8.50, 8.85, 9.25, 10.85, 11.50, 12.65, 22.50
Now there is no exact number in the middle so we must find the number in the middle of 9.25 and 10.85 which is 10.05
Thus 10.05 is the median

How many minutes and seconds worth of songs do you have?
______________.
How many hours and minutes is that equal to?
_____________.
Question 1:
48 + 63 + 28 + 44 + 43 = 226 minutes
41 + 40 + 15 + 1 + 39 = 136 seconds
136 seconds = 2 minutes and 16 seconds
The answer is 228 minutes and 16 seconds.
Question 2: 228 minutes = 3 hours and 48 minutes
The answer is 3 hours and 48 minutes, but if you're also counting seconds, add 16 seconds to the end of it.

Luke went shopping for a new pair of pants. The listed price of the pair of pants was $21, but the price with tax came to $22.05. Find the percent sales tax.
Answer:
5%
Step-by-step explanation:
22.05-21=1.05
1.05/21=.05
.05*100=5%
The sales tax is 5% of listed price.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, Luke went shopping for a new pair of pants.
The listed price of the pair of pants was $21.
But the price with tax came to $22.05.
The taxed amount
= $22.05 - $21
= $1.05
To find the percentage of taxed amount:
We use the percentage formula,
let m be the required percentage.
So,
1.05 = m x 21 /100
m = 1.05 x 100 / 21
m = 105 /21
m = 5%
Therefore, taxed amount is 5% of original price.

Dora makes an additional 3 bracelets. how much ribbon does Dora need in total now?
Answer:
2.45
Step-by-step explanation:
0.35 x (4 + 3) = 2.45
2.45 ribbon because 0.35 x 4 = 1.4 + 0.35 x 3 = 1.05. 1.05+1.4=2.45 or 4+3=7 0.35x7=2.45

This is 6th grade math
Answer:
40.5 in²
Step-by-step explanation:
It's pretty easy if you find the surface area of each and every shape alone first.
I see 2 squares and 4 rectangles.
Let's start by finding the surface area of the squares:
-The formula to finding the area of a square is length x length.
L×L
1.5 in x 1.5 in= 2.25 in²
2.25 in is the surface area of 1 square
but we have two squares so you do 2.25 in × 2 to get the surface area of both squares.
2.25 in² × 2= 4.5 in² (this is the surface area of both squares)
Now we calculate the surface area of the four rectangles.
Formula: L×W (length × width)
6 in × 1.5 in = 9 in² (s.a of one rectangle)
Since we have four rectangles, we'll have to multiply it by 4
9 in² × 4= 36 in²
Now we add the total surface areas of both the squares and the rectangles.
4.5 in² + 36 in²= 40.5 in²

PYTHAGOREAN THEOREM
Answer:
8. 20.8 units
9. isosceles
Step-by-step explanation:
8.The vertical altitude line divides the triangle into two congruent right triangles. Each has a horizontal leg of 4 units, and a vertical leg of 5 units. (You can find these lengths by subtracting coordinates, or by counting grid squares.)
slant sides
The hpotenuses of these right triangles are the short sides (PR, QR) of the larger triangle PQR. We can find their length using the Pythagorean theorem. Defining S as point (-2, -1), we have ...
PS² +SR² = PR² . . . . . . . . . . . . the Pythagorean theorem relation
4² +5² = PR² = 16 +25 = 41 . . . with numbers filled in
PR = √41 . . . . . . . . . . . . . . take the square root
PR ≈ 6.4 . . . . . . . . . . . round to tenths
horizontal side
The length of side PQ is 8 units, found by subtracting x coordinates ((2 -(-6)) = 8), by counting grid squares, or by doubling the length of PS (2(4) = 8).
perimeter
The perimeter of the triangle is the sum of its side lengths:
perimter = PR +QR +PQ = 6.4 +6.4 +8 = 20.8
The perimter of triangle PQR is 20.8 units.
__
9.Sides PR and QR are congruent, so the triangle is isosceles.

What is a function?An expression which defines the relationship between two variables (one independent and one dependent variable).
What is dependent and independent variable?The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes with the change of independent variable.
What is decreasing linear function?If the slope of the function is negative, that means the output value decreases as the input value increases is called a decreasing linear function.
How to find out which x-values would have the greatest corresponding y-value ?Since the function is decreasing,
The y-value will decarese with the increase in value of x.So, for the minimum value of x, there will be maximum value of y.
So, for the greatest value of y, the value of x will be -2 which is minimum of all the options.

Frequency for height 65" = 1
Frequency for height 66" = 1
Frequency for height 67" = 9
Frequency for height 68" = 8
Since we have to calculate the number of students having height less than 69"
Therefore, neglect the other frequencies.
