I have no idea.........

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.

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]

Answer:

I can't see it clearly but I can explain to you how to graph it on a number line :)

Step-by-step explanation:

Imagine the sign pooping the other way. Like > ___ The sign is pooping a LINE where the shorter angle is. So if the inequality was x>3 , You would put a dot on the 3 and do a line going right. Now to figure out if the dot is open or closed, it depends on the sign. If the sign is open, the sign is either > or <. If it is closed, the sign is either ≥  or ≤.

Applying the distance formula, the distance between the the Math building to the History building is: 5 units.

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:

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:

T = 3

Step-by-step explanation:

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

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:

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

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.

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
