The diagram below shows a three dimensional view of the pool.

shutvik [7]

Answer:

a) $A_{f} = 408.54\,m^{2}$ , b) $A_{w} = 106.2\,m^{2}$

Step-by-step explanation:

a) The floor area of the pool is:

$A_{f} = (10\,m)\cdot (12\,m)+(18\,m)\cdot (16.03\,m)$

$A_{f} = 408.54\,m^{2}$

b) The total area of the walls of the pool is:

$A_{w} = 2\cdot (0.9\,m)\cdot (16\,m) + (0.9\,m)\cdot (16\,m) + (18\,m)\cdot (1.8\,m)+ 2\cdot (12\,cm)\cdot (0.9\,m)+(10\,m)\cdot (0.9\,m)$

$A_{w} = 106.2\,m^{2}$

The height of a flare fired from the deck of a ship in distress can be modeled by h=-16t^2+104t+56, where h is the height of the

grin007 [14]

Answer:

7 seconds.

Step-by-step explanation:

We have been given that the height of a flare fired from the deck of a ship in distress can be modeled by $h=-16t^2+104t+56$ , where h is the height of the flare above water and t is the time in seconds.

The ball will hit the ground, when height will be 0 meters, so we will equate $h=0$ to find the time when ball will hit the ground as:

$-16t^2+104t+56=0$

Using quadratic formula, we will get:

$t=\frac{-104\pm\sqrt{104^2-4(-16)(56)}}{2(-16)}$

$t=\frac{-104\pm\sqrt{10816+3584}}{-32}$

$t=\frac{-104\pm\sqrt{14400}}{-32}$

$t=\frac{-104\pm120}{-32}$

$t=\frac{-104+120}{-32}\text{ or }t=\frac{-104-120}{-32}$

$t=\frac{16}{-32}\text{ or }t=\frac{-224}{-32}$

$t=-\frac{1}{2}\text{ or }t=7$

Since time cannot be negative, therefore, it will take 7 seconds for the flare to hit the ground.

If an angle is bisected to form two new 20 degree angles, what was the measure of the original angle?

garik1379 [7]

Answer:

40 degrees

Step-by-step explanation:

If the angle is split into 2 angles, each measuring 20 degrees, then the original angle measures 20(2)=40 degress.

Geometry, plz help!

astra-53 [7]

Answer:

17. surface area ≈ 441.84

04π m² or 1387.38 m²

18. Ratio of volumes = 8/27

19. volume of the smaller solid = 339 yards³

Step-by-step explanation:

17 .

To find the surface area of the sphere we have to find the radius of the sphere first.

volume of a sphere = 4/3πr³

volume = 1548π m³

r = ?

volume of a sphere = 4/3πr³

1548π = 4/3 × π × r³

multiply both sides by 3/4

1548π × 3/4 = πr³

4644π/4 = πr³

1161π = πr³

divide both sides by π

r³ = 1161

cube root both sides

r = ∛1161

r = 10.5101942

r ≈ 10. 51

surface area of a sphere = 4πr²

surface area = 4 × π × 10.51²

surface area = 4 × 110.4601 × π

surface area = 441.8404π m²

surface area = 441.8404 × 3.14 = 1387.378856 m² ≈ 1387.38 m²

If two figure or solid are similar with scale factor or ratio of x/y then the ratio of their volume is (x/y)³. If the ratio of of two similar prism is 2 : 3 the volume will be (2/3)³ = 8/27 .

If two solids are similar then the ratio of their surface area is the squared of the scale factor.

121/361 = (x/y)²

square root both sides

x/y = 11/19

If two solids are similar then the ratio of their volume is the cube of the scale factor.

(11/19)³ = a/1747

1331/6859 = a/1747

cross multiply

6859a = 2325257

divide both sides by 6859

a = 2325257/6859

a = 339.008164455

a ≈ 339 yards³

volume of the smaller solid ≈ 339 yards³
