If a dental patient is charged $65.97 for teeth cleaning, $127.12 for X-rays, and $94.50 for a dental exam, what should his tota

maks197457 [2]

The total should be 287.59. You add the numbers (127.12+94.50+65.97) and it should equal to that.

Slope=-6; passes through (-4,1)

Mila [183]

Answer:

Step-by-step explanation:

m = -6

Equation: y = mx + b

y = -6x +b

(-4 , 1)

Plugin x = -4 and y = 1 in the above equation

1 = -6*(-4) + b

1 = 24 + b

1- 24 = b

b = -23

Equation: y = -6x - 23

Write an equation of the parabola shown.

zzz [600]

Step-by-step explanation:

General equation of a parabola parallel to the x-axis: (y - k)^2 = 4p(x - h).

Vertex = (h, k) = (0, 0)

Directrix: x = h - p = -2.

Since h and k are 0, p must be 2.

Therefore the equation is y^2 = 8x.

These cones are similar. find the volume of the smaller cone. round to the nearest tenth.

Kamila [148]

Answer:

Volume of the smaller cone = 8.34 cm³

Step-by-step explanation:

"If two figures are similar, their dimensions will be proportional.

Following this rule,

Ratio of the dimensions of two cones = $\frac{\text{Radius of the large cone}}{\text{Radius of the small cone}}$

= $\frac{r_2}{r_1}$

= $\frac{5}{2}$

= 2.5

Similarly, "ratio of the volumes of two similar figures is cube of the dimensional ratio".

Ratio of the volumes = (ratio of the dimensions)³

$\frac{V_1}{V_2}=(2.5)^3$

$\frac{131}{V_2}=15.625$

$V_2=\frac{131}{15.625}$

= 8.384 cm³

≈ 8.4 cm³

Therefore, volume of the smaller cone is 8.4 cm³.
