Answer: -15.36, -1.44, 0.85, 4
Step-by-step explanation:
Step 1: Evaluate (solve) all of the expressions (equations)#1: -4.8x3.2= -15.36
#2: 2 1/4+ -1 2/5
2 1/4= 2.25
-1 2/5= -1.4
2.25+-1.4
*Whenever you have a +- something, it always becomes -
2.25 - 1.4= 0.85
#3: 4.32÷-3= -1.44
#4: -2 3/5 - -12/5
2 3/5= 2.6
-1 2/5= -1.4
2.6 - -1.4
*Whenever you have 2 minuses like - -, it always becomes a +.
So 2.6 - -1.4 becomes 2.6+1.4
2.6+1.4= 4
Step 2: List from least to greatest.Okay so the numbers we have are:
-15.36, 0.85, -1.44, 4
The least number is the one farthest away from 0. This number would be -15.36, because, here's a rule to remember:
The "bigger" the negative number looks, the smaller it actualy is beacuse it is farther away from 0. For example, -29 is smaller than -1 even though it looks bigger because -29 is farther from 0. If it were positive numbers, 29 would definitely be greater though.So -15.36 is the smallest or the least.
Next, you see that -1.44 is the next in line because its the only remaining negative number and it has to be smaller than the others, which are positive.
3rd of all, i know that 0.85 comes next on the list because it is smaller than 4. It is still above 0, making it positive.
Finally, 4 is the greatest. It's bigger than 0.85, which obviously is less than 1. Now here's the list of numbers from least--> greatest:
-15.36, -1.44, 0.85, 4
Now all you have to do is put these numbers into the boxes in order. If it doesn't make sense, try putting the first 2 numbers into the first 2 boxes. By doing this you get -15.36<-1.44, which is a true statment. If you want to go further, put 0.85 in the 3rd bubble to get -1.44<0.85 which is also true. Finally, when you put 4 in the last bubble, you get 0.85<4, which is true. That's how i know my answer is correct.
Hope this helps :))

What is the greatest common factor of 253 and 345?
Answers
Answer:
23
Step-by-step explanation:
To find the Greatest Common Factor, or GCF, we need to factor the first 2 numbers and then find the greatest number that is both present in the prime factorization of both numbers.
253 = 1 * 11 * 23
345 = 3 * 5 * 23
Since 23 is both present in both numbers and is the greatest, the GCF of 253 and 345 is 23.

Answer:
a)[tex](x^{2} +14x+40)ft^{2}[/tex]
b)14ft, 8ft
Step-by-step explanation:
a) Area of Rectangle = Length x Breadth
= [tex](x+10)(x+4)\\=x^{2} +4x+10x+40\\=(x^{2} +14x+40) ft^{2}[/tex]
b) Given Area of rectangle = [tex]112ft^{2}[/tex]
[tex]x^{2} +14x+40=112\\x^{2} +14x-72=0 (Quadratic Equation)\\\\[/tex]
Quadratic Equations: [tex]ax^{2} +bx+c = 0\\[/tex]
In this case, a = 1, b = 14, c = -72

Let the mass of one paperback be 'p' and one textbook be 't'.
Equation one:
sum of mass = total mass in box
20p + 9t = 44.4Equation two:
20p + 5p + 9t + 1t = 5125p + 10t = 51make 't' subject
10t = 51 - 25pt = 5.1 - 2.5pInsert this into equation one:
20p + 9(5.1 - 2.5p) = 44.4
20p + 45.9 - 22.5p = 44.4
20p - 22.5p = 44.4 - 45.9
-2.5p = -1.5
p = 0.6
The weight of 1 paperback is 0.6 pounds.
The weight of 1 textbook:
t = 5.1 - 2.5p
t = 5.1 - 2.5(0.6)
t = 3.6
The weight of 1 textbook is 3.6 pounds.

In Jason's class, 1/2 of the boys have brown eyes, 1/5 of the boys have blue eyes, and 3/10 of the boys have hazel eyes. How many more of the boys have brown eyes than hazel eyes?
Answers
Answer:
2
Step-by-step explanation:
ist you have to lind the lcd of each fraction. that would be 10.
1/2x5/5=5/10 of the boys have brown eyes
1/5x2/2=2/10 of the boys have blue eyes
3/10=3/10 of the boys have hazel eyes
The question is asking to see how many more boys have brown eyes than hazel eyes.
Subtract 3/10 from 5/10
and that gives you 2/10
The answer is 1/5.
We know that half of the boys in Jason's class has brown eyes, while three-tenths of the boys in his class have hazel eyes. Therefore, if we subtract the two values, you should get your answer.
[tex]\frac{1}{2} -\frac{3}{10} =\frac{2}{10}[/tex]
1/5 is the simplified version of 2/10. Therefore, 1/5 is your answer.

Mary's desk was 67.94 inches long, Joe's desk was 78.26 inches long and Troy's desk was x inches long. If the length of all the desks combined was 214.62 inches, how long was Troy's desk?
Answers
Answer:
68.42
Step-by-step explanation:
We know that when we add the lengths of all of the desks together, the total is 214.62. Based on that information, we can set up the following equation: 67.94 + 78.26 + x = 214.62. From there, all you have to do is add 67.94 + 78.26 to get 146.2. Lastly, you simply do 214.62 - 146.2 to get 68.42. Hope this helps!

(i) Equation : y = 6.25x + 65
(ii) Price of each ticket : $6.25
(iii) Money originally in the box : $65
Explanation:
Here from table, identify the coordinates given.
Coordinates:
(7, 108.75)(13, 146.25)(18, 177.50)Find slope:
[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]
[tex]\rightarrow \sf slope \ (m) : \dfrac{146.25-108.75}{13-7} = 6.25[/tex]
Slope is also the price of each ticket which is $6.25
Equation:
[tex]\sf y - y_1 = m(x - x_1)[/tex]
[tex]\rightarrow \sf y - 108.75 = 6.25(x - 7)[/tex]
[tex]\rightarrow \sf y - 108.75 = 6.25x - 43.75[/tex]
[tex]\rightarrow \sf y = 6.25x - 43.75 + 108.75[/tex]
[tex]\rightarrow \sf y = 6.25x +65[/tex]
To find the amount of money in the box originally, insert x which represents number of tickets sold as 0.
Originally amount of money:
[tex]\rightarrow \sf y = 6.25(0) +65[/tex]
[tex]\rightarrow \sf y = 65[/tex]
Hence, there were $65 in the box before any tickets were sold.

The two numbers common in the multiples seen above are 10 and 20, because they are multiples of both 2 and 5. However, 10 is less than 20, which would render it to be the lowest common denominator. In cases like this, the lowest integer (the number closest to 0) will always be the LCD.

In^2 this multiplies the number used by itself therefore in your case 283 x 283. You are using the measurement for inches.
Answer: C
Step-by-step explanation:
A says the polygon's measurements are 283 inches by 283 inches. Is it Correct? No. If we multiply these numbers we get 80,089 inches squared, which is not equal to our actual surface of 283 inches squared.
B says the polygon's volume is 283 inches cubed, which is not correct because it says that a certain measurement of a polygon is 283 inches squared, not cubed, which means we got a surface/area, not a volume.
C says that our 283 inches squared area could fit 283 one-inch by one-inch squares, which is correct because one-inch by one-inch is an one inch squared area, if we multiply this one-inch squared by the number 283, we get 283 inch squared area.
