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

Simplify the expression. -2/3c -9/5 + 14c + 3/10
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
[tex]13 \frac{1}{3}c - 1 \frac{1}{2} [/tex]

[tex] \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]
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]

Chris wants to ride on the Colossal Coaster at the amusement park. Admission to the park
costs $6 and each ride on the roller coaster costs an additional $0.50. Chris wants to spend less
than $12.50 in all. Find the number of times that Chris can ride on the roller coaster.
Solve using inequalities
Answer:
He can ride it 4 times
Step-by-step explanation:
Answer:
12 times
Step-by-step explanation:
$6 + $0.50 (x) < $12.50
x is the amount of times he can ride. Since he wants to spend less then 12.50 then he can't go more then 13 times but 13 is spending all his money so 12 times is $0.50 less then his specified amount he wants to spend.
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?
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.

Answer:
Step-by-step explanation:
22. Area = L x B
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)
Area =6m^3n^2
Perimeter = L + B + H
Perimeter = 3mn^2 + 4m^2 + 7mn^2
Perimeter = 10mn^2 + 4m^2

Find the commission.
Earning Commission
Sales Commision Rate Commission
$540
8%
?
The commission is $
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

What’s the surface area need help ASAP
Answer:
144 m^2
Step-by-step explanation:
the front side is 9 m tall and 6 m long. The formula for the surface are of triangles is W*L/2, so 9*6=54, 54/2=27. Four sides are the same, so multiply 4 to get 108m. the the faced down part is 6m by 6m, so multiply 6*6 is 36, then add up 36 + 108 = 144m.

Answer:
Part A: Write an equation.
If the present age is y, then n times the present age = ny.
If the present age is x, then age n years later/hence = x + n.
If the present age is x, then age n years ago = x – n.

Part B: Solve the equation.
John’s age =
John’s sister’s age =
Answer:
sister = 6 years
John=18 years
Step-by-step explanation:
A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.

15% of 95? and 3 1/2% of 100?
Answer:
15% of 95-14.25
3 1/2% of 100-3.5
Step-by-step explanation:
Answer:
15% of 95= 14.25
3 1/2% of 100= 3.5
Step-by-step explanation:
3 1/2% of 100= 3.5, because 1% of 100=1
15% of 95=14.25 because 10% = 9.5 and 5% of 95=4.75
4.75+9.5= 14.25
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?
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.
