Answer:

36 tiles

Step-by-step explanation:

Since there is 1 extra tile on each side of the 8x8 pool, we can say that the entire area of the picture is 10x10.

Subtracting 8x8 from 10x10 we get

(10x10) - (8x8) = ?

100 - 64 = 36

36 tiles are around the 8x8 pool

The height of the window is 9-x feet.

Given that, a window is 9 ft long. It is x feet longer than it is high.

We need to find what is the height of the window.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Here, the length of the window = 9 ft

Then, the height of the window = x feet smaller than the length = 9-x feet

Therefore, the height of the window is 9-x feet.

Answer:

868 miles

Step-by-step explanation:

cm to miles ? are you sure you got the problem description right ? because cm are part of the metric system (mm, cm, meters, kilometers), while miles are part of American/ UK systems. and they don't deal with cm.

but ok, so, we will not deal with conversion rates, we will just apply the scale factors.

2.5 cm <-> 620 miles

3.5 cm <-> ? miles

that is determined by the factor to go from 2.5 to 3.5 cm. the same factor then had to be applied to the miles.

2.5 × f = 3.5

f = 3.5 / 2.5 = 7/2 / 5/2 = 7/2 × 2/5 = 7×2 / 2×5 = 7/5

=>

620 × 7/5 = 868 miles

Quadrant II - +

Step-by-step explanation:

3,-4 translated 5 up is 3,1 then 4 units left is -1,1

This is because there are 20 women out of 50 people total (30+20 = 50).

So 20/50 = 2/5

This converts to the decimal form 0.4 and the percentage form 40%

Answer:

x=-15

Step-by-step explanation:

-3x+5(x+2)=4x-(3x+5)

<=>-3x+5x+10=4x-3x-5

<=>-3x+3x+5x-4x=-10-5

<=>x=-15

Answer:

x=-15/7

Step-by-step explanation:

combine like terms

3x +5x +10=4x-4x+5

distribute

8x+10=4x-3x-5

combine like terms

8x+10=1x-5

subtract 10 from both sides

8x=x-15

subtract x from both sides

8x-x=x-15-x

combine like terms

divide both by 7

7x-15

Answer:

$1,111

Step-by-step explanation:

Let x = principal amount

x multiplied by 1.045 will equal the final amount

Since 50 was earned, x + 50 will also equal the final amount

1.045x = x + 50

Let's move the x terms to left side by subtracting both sides by x

1.045x = x + 50

- x        - x

0.045x = 50

Divide both sides by 0.045 to isolate the x variable

0.045x/50 = 50/50

x = 1,111.111111111

Answer:

  $9.00

Step-by-step explanation:

The simple interest formula can be used.

  I = Prt . . . . . interest on principal P invested at rate r for t years

  I = ($1200)(0.06)(1/8) = $9.00

The simple interest Xander would earn is $9.00.

Justification: the interest is computed using the appropriate formula.

Step-by-step explanation:

I'm going to lay this out in a chart so it's a little easier to see:

F(x) = f(g(x))

x | f (x) | f ' (x) | g (x) | g ' (x)

--------------------------------------

-2 | 8 | 4 |

5 | | 3 | -2 | 6

Remember the chain rule, which says

(f (g (x))) ' = g ' (x) f ' (g (x))

When they ask for F ' (5), they are asking for (f (g (x))) ' when x = 5.

Using the chain rule, that's

F ' (5) = g ' (5) f ' (g (5))

We can simplify using the numbers provided.

F ' (5) = (6) f ' (-2)

F ' (5) = (6) (4)

F ' (5) = 24

I hope that helps!

The required simplified solution of the F'(5) is 24

Given that,
F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5)=-2, gʻ(5) = 6..
To determine F'(5),

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
F(x) = f(g(x))
Now,
F'(x) = (f (g (x))) '
Following the chain rule
F'(x) = g ' (x) f ' (g (x))
Now,
x = 5
F'(5) = g'(5)f'(g(5))
substitute the value in the above equation,
F'(5) = 6 × f'(-2)
F'(5) = 6 × 4
F'(5) = 24

Thus, the required simplified solution of the F'(5) is 24.

Answer:

8 units

by step explanation:

Since AB and DC are parallel to each other;

Then x + 2x = 180°

3x = 180°

x = 180/3 = 60°

∆ABC = 60° and ∆ ADC = 120°

∆BAD = 60° (adjacent angles of a trapezoid add up to 180°)

As shown in the figure attached, part of line AB is equal to 3 units and part is equal to: (c) units * 2 .

[tex] \frac{c}{5} = \cos(60) = \frac{1}{2} [/tex]

c = 2.5 units

Hence length AB is equal to; 2(2.5) units + 3 units = 8 units
