Answer:

28 years

Step-by-step explanation:

The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value

Answer:

1442.9 = 1.4429 x 10 ^1000

Step-by-step explanation:

PEMDAS

4.3 × 107 + 9.1 × 108 = _____ x 10 ^----

(4.3 × 107) + (9.1 × 108) = _____ x 10 ^---

460.1 + 982.8 = _____ x 10 ^----

1442.9 = 1.4429 x 10 ^1000

This is the right answer, I think you may have forgotten to put the ^.  

Answer:

9.53 × 108

Step-by-step explanation:

Make sure both numbers have the same exponent

4.3 × 107 = 0.43 × 108

Then add the coefficients

0.43 × 108 + 9.1 × 108 = 9.53 × 108

Answer:

what? pls translate it to english

Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)

Multiply the original price by 80%

36 x 0.8 = 28.80

The sale price is £28.80

Answer:

Area is 585

Step-by-step explanation:

Using the area formula A = [tex]h_{b}[/tex] b / 2 you can substitute the given values into it to find the area of the triangle.

Given Values:

- Base: 45

- Height: 26

So,

26 x 45 / 2

=> 1170 / 2

=> 585

Area: 585

Answer:

x = 4

Step-by-step explanation:

Given

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]

Multiply through by (x + 3)(x + 4) to clear the fractions

3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side

3x + 9 - x - 4 = x + 9

2x + 5 = x + 9 ( subtract x from both sides )

x + 5 = 9 ( subtract 5 from both sides )

x = 4

Answer:

the side length of the cube is 4.10

Step-by-step explanation:

The computation of the side length of the cube is shown below:

As we know that

The volume of the cube is side^3

So,

69^3 = s^3

Now the side length of the cube is

= ∛69

= 4.10

Hence, the side length of the cube is 4.10

The same would be considered and relevant too

The above formula should be applied for the same

Answer:

B

Step-by-step explanation:

A has 2 it crosses the x axis 2x

B Has 1.

C has 2

D has none since it never touched the x axis

Option B is correct.

If the graph of quadratic function crosses x - axis at two points then that function has two zeros.

Therefore, Option B graph represent a quadratic function that has only one zero.

Answer:

65

Step-by-step explanation:

Do the opposite of what the question gives you.

Sara has the number 11. She divided by 7, so you would multiply by 7:

11 x 7 = 77

Next, Sara added 12, so you will subtract by 12:

77 - 12 = 65

65 is the number Sara was thinking of.

Answer:

Widgets: 12

Wombats: 15

Step-by-step explanation:

Let x represent widgets

y represent wombats

Set up the equations

(1) x + y = 27

(2) 0.75x + 1.25y = 27.75

Solve equation (1), x + y = 27 for x

x = 27 - y

Substitute 27- y for x into equation (2)

0.75(27 - y) + 1.25y = 27.75

0.5y + 20.25 = 27.75

0.5y = 7.5

y = 15

Substitute 15 for y into equation (2)

x = 27 - 15

= 12
