Simplify the expression. -2/3c -9/5 + 14c + 3/10
Answers
Answer:
[tex]13 \frac{1}{3} c - 1 \frac{1}{2} [/tex]
Step-by-step explanation:
We want to combine alike terms so
-2/3c+14c & -9/5+3/10
14c-2/3
[tex] \frac{14}{1} c - \frac{2}{3} c[/tex]
Multiply 14/1 by 3/3 to get the denominators the same
[tex] \frac{42}{3} c - \frac{2}{3} c[/tex]
Subtract
[tex] \frac{40}{3} c[/tex]
simplify
[tex]13 \frac{1}{3} c[/tex]
now
[tex] \frac{3}{10} - \frac{9}{5} [/tex]
Multiply 9/5 by 2/2
[tex] \frac{3}{10} - \frac{ 18}{10} [/tex]
Subtract
[tex] - \frac{15}{10} [/tex]
Simplify
[tex] - 1 \frac{1}{2} [/tex]
put both together

Answer:
1) | - 4 | < | -6 | is true
2) | - 1 | > | 7 | is false
3) | -8 | < - 2 is false
Step-by-step explanation:
We need to find if the statements are true or false.
1) | - 4 | < | -6 | true or false
We know that:
|-4| = 4
|-6| = 6
Now, 4 < 6 is true
So, | - 4 | < | -6 | is True
2) | - 1 | > | 7 | true or false
We know that:
|-1| = 1
Now, 1 > 7 is false, because 1 is less than 7 and not gr eater than 7.
So, | - 1 | > | 7 | is false
3) | -8 | < - 2 true or false
We know that
|-8|= 8
Now, 8 < 2 is false, because 8 is not less than 2, it is greater than 2.
So, | -8 | < - 2 is false

Find the commission.
Earning Commission
Sales Commision Rate Commission
$540
8%
?
The commission is $
Answers
Answer:
The commission is $43.20
Step-by-step explanation:
Given that:
Amount of sales = $540
Commission rate = 8%
We have to find the amount of commission from the sales of $540.
Amount of commission = 8% of sales
Amount of commission = [tex]\frac{8}{100}*540[/tex]
Amount of commission = 0.08 * 540
Amount of commission = $43.20
Hence,
The commission is $43.20

Answers
Answer:
[tex]\displaystyle \frac{(a - b)^{2} - {c}^{2} }{{a}^{2} - {(b+ c)}^{2} } + \frac{(b - c)^{2} - {a}^{2} }{{b}^{2} - {(c+ a)}^{2} } + \frac{(c - a)^{2} - {b}^{2} }{{c}^{2} - {(a+ b)}^{2} }=1[/tex]
Step-by-step explanation:
Algebra Simplifying
We are given the expression:
[tex]\displaystyle T=\frac{(a - b)^{2} - {c}^{2} }{{a}^{2} - {(b+ c)}^{2} } + \frac{(b - c)^{2} - {a}^{2} }{{b}^{2} - {(c+ a)}^{2} } + \frac{(c - a)^{2} - {b}^{2} }{{c}^{2} - {(a+ b)}^{2} }[/tex]
We need to repeatedly use the following identity:
[tex](a^2-b^2)=(a-b)(a+b)[/tex]
For example, the first numerator has a difference of squares thus we factor as:
[tex](a - b)^{2} - {c}^{2} =(a-b-c)(a-b+c)[/tex]
The first denominator can be factored also:
[tex]{a}^{2} - {(b+ c)}^{2} = (a-b-c)(a+b+c)[/tex]
Applying the same procedure to all the expressions:
[tex]\displaystyle T=\frac{(a - b- c)(a-b+c) }{a-b-c)(a+b+c) } + \frac{(b - c - a)(b-c+a) }{(b-c-a)(b+c+a) } + \frac{(c - a-b)(c-a+b) }{(c-a-b)(c+a+b)}[/tex]
Simplifying all the fractions:
[tex]\displaystyle T=\frac{a - b- c}{a+b+c} + \frac{b-c+a}{b+c+a } + \frac{c-a+b }{c+a+b}[/tex]
Since all the denominators are equal:
[tex]\displaystyle T=\frac{a - b+ c+b-c+a+c-a+b}{a+b+c}[/tex]
Simplifying:
[tex]\displaystyle T=\frac{a +c+b}{a+b+c}[/tex]
Simplifying again:
T = 1
Thus:
[tex]\boxed{\displaystyle \frac{(a - b)^{2} - {c}^{2} }{{a}^{2} - {(b+ c)}^{2} } + \frac{(b - c)^{2} - {a}^{2} }{{b}^{2} - {(c+ a)}^{2} } + \frac{(c - a)^{2} - {b}^{2} }{{c}^{2} - {(a+ b)}^{2} }=1}[/tex]

The buildings of a university are mapped on a coordinate grid with the origin being at library.
The Math building is located at the point (1, 5) and the History building is located at (4, 9).
How far is it from the Math building to the History building?
Answers
Applying the distance formula, the distance between the the Math building to the History building is: 5 units.
What is the Distance Formula?To find the distance between two given points on a coordinate grid, the distance formula which is used is: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
Given the following:
Math Building (1, 5) = (x1, y1)History building (4, 9) = (x2, y2).Plug in the values into the distance formula:
d = √[(4−1)² + (9 − 5)²]
d = √[(3)² + (4)²]
d = √(9 + 16)
d = √25
d = 5
Distance between the the Math building to the History building is: 5 units.

Area = (5a^2b^4) x (3ab^2)
Area = 15a^3b^6
Perimeter = L + B
Perimeter = (5a^2b^4) + (3ab^2)
Preimeter = 5a^2b^4 + 3ab^2
23. Area = 1/2 bh
Area = 1/2 (3mn^2) x (4m^2)

A greyhound dog can run with a top speed of 17.6 m/s. At this rate, how long will it take to run 100 meters?
Answers
Answer:
It will take 5.68 seconds to cover a distance of 100 meters.
Step-by-step explanation:
Given that:
A greyhound dog runs with a top speed of 17.6 m/s
Distance to cover = 100 meters
We know that:
Distance = Speed * Time
Putting the values in formula
100 = 17.6 * Time
Time = [tex]\frac{100}{17.6}[/tex]
Time = 5.68 seconds
Hence,
It will take 5.68 seconds to cover a distance of 100 meters.
