The overall width of the path and garden is 12 feet.

The area of the entire garden and path is 12 x 12 = 144 square feet.

The path is 1 foot wide, so the garden would be 12 - 2 = 20 feet wide.

The area of the garden only would be 10 x 10 = 100 square feet.

The area of the path only = 144 - 100 = 44 square feet.

1 bag covers 9 square feet:

44 / 9 = 4.88

You would need 5 bags.

a door with width 4.20 m has an arc as shown in diagram .Find: a) radius of the arc B) length of the arc to the nearest cm
EastWind [94]

Answer:

Ok, we know that the width of the door is 4.20m.

Then, if the arc is at the top of the door, we will have that the diameter of that "half circle" will be equal to the width of the door.

Then the diameter of the arc is 4.20m

And the radius is defined as half of the diameter, so we have:

radius = 4.20m/2 = 2.10m

And we can write this in cm (because the probelm ask for it)

1m = 100cm

then 2.10m = 2.1*100cm = 210cm

Now, we know that the perimeter of a circle is:

P = 2*pi*r

where pi = 3.14

Then the perimeter (or arc) of half a circle will be half of that:

Arc = (2*pi*r)/2 = pi*r

and r = 210cm, pi = 3.14

Arc = 3.14*210cm = 659.4cm

Find the area of the shape . ( exact answer )
tangare [24]

Answer:

84.78

Step-by-step explanation:

A=π r²

6*6(r²)=36

36*3.14(π)=113.04

113.04*3/4(it is 3/4 of a circle)=339.12/4

339.12/4=84.78

AnnyKZ [126]

Answer:

The equation for this line would be y = -20x + 200. The y-intercept is 200 and represents the amount of money Mrs. Temps owes Mrs. Abruzzino in the beginning. The slope is -20 which represents how much Mrs. Temps pays back Mrs. Abruzzino each month. The x-axis should increase by 1 months.

I need help with this please the answers I can choose from are
STatiana [176]

Sum of interior angles of a △ = 180°

∴ ∠T + ∠V + ∠U = 180°

⇒ 37° + 63° + X° = 180°

⇒ X° + 100 = 180°

⇒ X° = 180° - 100°

⇒ X° = 80° (D).
