Answer:

$\Large \boxed{\sf 384 \ m^2}$

Step-by-step explanation:

Surface area ⇒ area of 2 triangles + area of 3 rectangles

$(8 \times 3 \times 0.5 \times 2)+(20 \times 5 \times 2+20 \times 8)=384$

Answer:

Step-by-step explanation:

I'm guessing you want the volume?

so for a triangle it's 1/2 base * height for the area

1/2 * 8 * 3 = 12

12*20=240 m^3

Which is the equation of a circle whose center is at the origin and that passes through the point (3, 5)?

xxTIMURxx [149]

Answer:

x² + y² = 34

Formula:

(x - h)² + (y - k)² = r² where (h, k) is the center

<u>Here find the radius using distance formula</u>: → origin : (0, 0)

√(x2-x1)²+(y2-y1)²

√(3-0)²+(5-0)²

√9+25

√34

<u>Thus the equation of circle</u>:

(x - 0)² + (y - 0)² = (√34)²

(x - 0)² + (y - 0)² = 34

x² + y² = 34

The groundhog population of Punxsutawny, Pennsylvania is closely monitored each year. Two years ago the population decreased by

kap26 [50]

Answer:

There was a increase of 1.7% over these three years

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: $\frac{100-a}{100}$

For a increase of a%, we multiply by: $\frac{100+a}{100}$

What was the percentage increase/decrease of groundhogs over these three years?

Decrease of 12%(multiplication by 0.88).

Increase of 6%(multiplication by 1.06).

Increase of 9%(multiplication by 1.09).

After these three years:

0.88*1.06*1.09 = 1.017

1.017 - 1 = 0.017

0.017*100% = 1.7%

There was a increase of 1.7% over these three years

To win a prize at a fair you must throw a coin into a space that is 7.0 cm long and 4.0 cm wide. what is the area of the space y

dlinn [17]

Alright, lets get started.

space that is 7.0 cm long and 4.0 cm wide it means space is in rectangular shape.

The lenght of the space = 7 cm

The width of the shape = 4 cm

The formula of area of rectange = length * width

The area of rectange = $7*4$

The area of rectange = 28 square cm

So, the area of the space you are aiming for 28 square cm. : Answer

Hope it will help :)
