A rectangle is 15 cm wide and 18 cm long. If both dimensions are
decreased by the same amount, the area of the new rectangle formed is
116 cm less than the area of the original. Find the dimensions of the
new rectangle

Answer:

-200 isn't higher than 450 but 450 is:

450 is 250 higher than -200

Step-by-step explanation:

The height of the building is approximately 105 ft.

According to the question,

We have the following information:

The angle made from their location to the building = 59°

The distance of the building from their location = 63 ft

Now, we can find the height of the building by using trigonometric function of tan.

We know that tan is equal to perpendicular/base.

In this case, perpendicular is the height of the building and base is the distance of the location from the building.

We have:

Tan 59° = Height of the building/distance of the building from the location

We know that the value of tan 59° is 1.6643.

Let's take the height of the building to be H ft.

1.6643 = H/63

H = 1.6643*63 ft

H = 104.85 ft

Now, this number can be rounded off to 105 ft.

Hence, the correct option is a.

Answer: 2/3

Step-by-step explanation:

y=mx+b

Answer:

2/3

Step-by-step explanation:

the equation is in y=mx+b form and m=slope so 2/3 would be the slope.

hope this helped :)

Step-by-step explanation:

step 1. the x intercept is when y=0.

step 2. 2x -5(0) = 20 or x = 10.

step 3. the x intercept is (10, 0)

step 4. the y intercept is when x=0.

step 5. 2(0) - 5y = 20 or y = -4

step 6. the y intercept is (0, -4).

The answer is -2a because first you multiple the number and eliminate redundant perenthese then last combine like terms and that how you get -2a

Answer:

a = 4 , b = -2

Step-by-step explanation:

3a + b = 10

2a + 4b = 0

(By using elimination method, eliminate one variable) - to get only one equation

(3a + b = 10 ) 4

2a + 4b = 0

12a + 4b = 40

(minus)

2a + 4b = 0

10a = 40

a = 40/10

a = 4

(substitute a into an equation to get b)

2a + 4b = 0

2(4) + 4b = 0

4b = 0 - 8

b = -8/4

b = -2

Answer:

The answer is

[tex]5 \sqrt{2} [/tex]

Step-by-step explanation:

By using Pythagoras

Then

[tex] {y}^{2} + {y}^{2} = {10}^{2} \\ 2 {y}^{2} = 100 \\ {y}^{2} = 50 \\ y = \sqrt{50} = \sqrt{2 \times 25} = 5 \sqrt{2} [/tex]

Do you mean exponential form as in scientific notation or as in prime factorization.

Now matter I will do both.

As in scientific notation.

200*75

=150*100

=1.5*10000

=1.5*10^4

As in prime factorization.

200*75

=2^3*5^2*3*5^2

=2^3 * 3 * 5^4

Answer:

m = [tex]\frac{-1}{2}[/tex]

Step-by-step explanation:

To find the slope of most lines, we should rearrange the equation into the slope-intercept form or y = mx + b.

So,

2x + 4y = 8

4y = -2x + 8

[tex]y=\frac{-2x +8}{4}[/tex]

[tex]y=\frac{-2}{4}x+\frac{8}{4}[/tex]

[tex]y=\frac{-1}{2}x+2[/tex]

The slope is the coefficient of the x term, so

m = [tex]\frac{-1}{2}[/tex]

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

2x+4y=8

4y = -2x +8

y = [tex]-\frac{2}{4}[/tex]x + [tex]\frac{8}{4}[/tex]

y = [tex]-\frac{1}{2}[/tex]x + 2

y=mx+b so the slope is m=[tex]-\frac{1}{2}[/tex].  

parallel lines have the same slope.

Answer:

£6368

Step-by-step explanation:

You can start by making a formula, which will be:

100/100=1

1.5/100=0.015

1+0.015=1.015 (your multiplyer)

6000*1.015^n= your money after 4 years

(n represents the number of years)

Now you just put in the number of years:

6000*1.015^4=6368.181304

Now round:

Answed= £6368
