Answer:

b. six equilateral triangles

Step-by-step explanation:

The 6 interior angles of the hexagon are supplementary to the exterior angle and are 120 deg. ... Therefore the angles at the center is 360/6 = 60 degrees for each triangle. So all three angles of the six triangles are 60 deg each. So there are 6 equilateral triangles that form the regular hexagon.

Half of your baseball card collection got wet and was ruined. you bought 14 cards to replace some that were lost.how many did yo

Mamont248 [21]

Because you added 14 cards to your collection, we'll have to subtract that:

40 - 14 = 26

Knowing that 26 cards is half of your old card deck, we know that your old card deck is:

26*2 = 52

You have option b. 52 cards before.

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.

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (assume that

Lilit [14]

Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3

The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
