125.85 meter in gigameter = 1.2585 x 10⁻⁷

Step-by-step explanation:

Given:

125.85 meter

Find:

125.85 meter in gigameter

Computation:

1 Gm = 1,000,000,000 m

125.85 meter in gigameter = 125.85 x 10⁻⁹

125.85 meter in gigameter = 1.2585 x 10⁻⁷

Answer:

1) [tex]49 {a}^{2} - 16 {b}^{2} [/tex]

2) [tex]251502[/tex]

Step-by-step explanation:

a) Question :-[tex](7a - 4b)(7a + 4b)[/tex]

Identity used here :-[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]

So,

[tex](7a + 4b)(7a - 4b)[/tex]

[tex]=> {(7a)}^{2} - {(4b)}^{2} [/tex]

[tex]=> 49 {a}^{2} - 16 {b}^{2} [/tex]

b) Question :- [tex]501 \times 502[/tex]

Identity used here :-[tex](x + a)(x + b) = {x}^{2} + (a + b)x + ab[/tex]

So,

[tex]501 \times 502 = (500 + 1)(500 + 2)[/tex]

[tex] = > {(500)}^{2} + (1 + 2)500 + 1 \times 2[/tex]

[tex] = > 250000 + 1500 + 2[/tex]

[tex] = > 251502[/tex]

Step-by-step explanation

I have NEVER in my life seen a dog with pants on its back legs, only on both so yeah.

Answer: B.

Step-by-step explanation:

Suppose you have a L.L. Bean coupon of $63.60 and you want to know the final or sale price if the discount is 20 percent.

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 63.60 - 12.72

Sale Price = $50.88 (answer).

This means the cost of the item to you is $50.88.

You will pay $50.88 for a item with original price of $63.60 when discounted 20%.

In this example, if you buy an item at $63.60 with 20% discount, you will pay 63.60 - 12.72 = 50.88 dollars.

Answer: $50.88

Step-by-step explanation:

Step 1: Find 20% of 63.60

20% of 63.60

20% = 20/100 = 0.2

0.2 × 63.60 = 12.72

20% of 63.60 is removed to get the selling price.

Step 2: Subtract

20% of 63.60 = 12.72

63.60 - 12.72 = 50.88

The selling price is $50.88.

Answer:

Step-by-step explanation:

2.5x + 2.5x + x = 60

x= 10

2.5x = 25

the sides of the triangle are 25, 25, 10

I don't know what you mean by "midpoints of the triangle".

Answer:

x = 20

Step-by-step explanation:

You can solve this problem using similar triangles; you know the triangles are similar due to the AAA property because of the Corresponding Angles Theorem.

To find x, you need to identify what sides 8 and x correspond to:

8 corresponds to 14 (6 + 8)

x corresponds to (x + 15)

Now, you need to find the scale factor by dividing 14 by 8:

14 ÷ 8 = 7/4

At this point, you can write and solve an equation for x:

7/4x = x + 15

3/4x = 15 (subtract x from both sides)

x = 20 (multiply both sides by 3/4)

26

Answer:

38.5, 77, 192.5

Step-by-step explanation:

x + 2x + 5x = 308

8x = 308

x = 38.5

38.5 + 2(38.5) + 5(38.5)

38.5 + 77 + 192.5 = 208

38.5, 77, 192.5

Answer: 1430 girls

Step-by-step explanation:

In order to solve this we must take it step by step. So first things first. There are 12,481 people at this concert. If 8906 are adults we need to subtract to find out how many children there are. 12481-8906=3575. There are 3,575 children at this concert. Now if 3/5 of the children are boys then the other missing 2/5 must be the girls. There are a couple of ways to solve this but im going to go the direct route. multiply 3/5 by 3,575 to get 2,145 boys. Now if 2,145 out of 3,575 are boys then 3575-2145= 1430 girls

Let's sum up what we learned

1. 12,481 people are at a concert

2. 8906 adults are at this concert

3. 3,575 are children

4. 2145 are boys

5. Which means there are 1430 girls

Answer:

929,477.13

Step-by-step explanation:

Number of years, n = 20

Using the relation :

a(1- r^n)/ (1 - r) ;

where a is the first term, r is the common ratio and n is the number of years

a = 19000

r = 1 + 8.6% = 1.086

19000(1 - 1. 086^20) / (1 - 1.086)

19000(1 - 1.086^20) / (1 - 1.086)

−79935.0336930 / (1 - 1.086)

= 929,477.13
