To calculate the percentage increase, work out the difference (increase) between the two numbers you are comparing. Then divide the increase by the original number and multiply the answer by 100.

To make a percentage out of a decimal, you must move it 2 places to the right of a number.
For example, 0.10 = 10%, 0.25 = 25%

Can someone please help me? I don't understand question d.

Answer:

Step-by-step explanation:

From the previous answers you know the angles and side lengths of the triangle:

α = 60°

Ф = 30°

and the side lengths:

1,2 and √3.

Remember:

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = opposite / adjacent

Now you can read off from the triangle:

sin 30° = 1/2

cos 60° = 1/2

sin 60° = √3/2

cos 30° = √3/2

tan 30° = 1/√3

tan 60° = √3

What is the area of a rectangle with vertices (-8, -2), (-3,-2), (-3,-6), and (-8,-6)?

Gemiola [76]

Answer:

The area of the rectangle is 20 square units

Step-by-step explanation:

Through the x values of the ordered pairs, we can see that the length of the rectangle is 5

$-3-(-8)=5$

Through the y-values of the ordered pairs, we can see that the width of the rectangle is 4

$-2-(-6)=4$

The area can be found by multiplying the length and width, so this means

$(5)(4)=20$
