Answer:

42.5 Units squared

Step-by-step explanation:

Rectangle: 9.0 * 3.5 = 31.5

Square: 2 * 2 = 4

Left Triangle: 2 * 2 * .5 = 2

Right triangle: 5 * 2 * .5 = 5

31.5 + 4 + 2 + 5 = 42.5

A conical perfume bottle has a radius of 3.2 centimeters and a height of 3.9 centimeters.
ioda

For this case, we must find the volume of the perfume bottle, given by the volume of a cone.

V = \frac {\pi * r ^ 2 * h} {3}

Where:

r: It's the radio

h: It's the height

Substituting the values:

V = \frac {3.14 * (3.2) ^ 2 * 3.9} {3}\\V = \frac {125.39904} {3}\\V = 41.79968 \ cubic \ centimeters

Round off:

V = 41.80 \ cubic \ centimeters

Thus, the bottle contains 41.80 cubic centimeters of perfume

How do you do 56 through 58? Thanks to anyone who awnsers!
astraxan [27]

Hello !

56)

5 {x}^{2}  + 8x =  - 1 \\ 5 {x}^{2}  + 8x + 1 = 0

\Delta =  {b}^{2}  - 4ac \\  =  {8}^{2}  - 4 \times 5 \times 1 \\  = 64 - 20 \\  = 44

The value of the discriminant is 44.

57) ∆>0 : there are two solutions.

58)

x_1 =  \frac{ - b +  \sqrt{\Delta} }{2a}  \\  =   \frac{ - 8 +  \sqrt{44} }{2  \times 5}  \\  =  \frac{ \sqrt{11} - 4 }{5}

x_2 =  \frac{ - b - \sqrt{\Delta} }{2a} \\  =  \frac{ - 8 -  \sqrt{44} }{2 \times 5}   \\  =  \frac{ -  \sqrt{11} - 4 }{5}

Have a nice day

Kiana's soccer team's ratio of wins to losses is 5:3. Her team has played 24 games. How many games have they won?​
Bas_tet [7]

The win-to-loss ratio of 5:3 is a "part-to-part" ratio, so we can represent each part as a fraction of the whole. We can do this by simply adding 3 + 5 = 8 (the "whole") and dividing by that total. This gives us a ratio of Images, which means that the Bombers won Images of their games and lost Images of them. Since they played a total of 120 games, they won Images games and lost Images games.

Solve 2.7=x/12 thank you!
olganol [36]
2.7 = 27/10

27/10 = x/12
cross multiply
10x = 324
divide both sides by 10
x = 32.4
