Two similar cones have volumes of 3970cm3 and 3100 cm3 respectively.

Answer:

The height of the smaller cone is 19.52 cm

Step-by-step explanation:

Given that,

The volume of cone 1, V₁ = 3970 cm³

The volume of cone 2, V₂ = 3100 cm³

The height of the larger cone, h₁ = 25 cm

We need to find the height of the smaller cone. Let it is h₂. For similar cones,

\dfrac{V_1}{V_2}=\dfrac{h_1}{h_2}

Put values,

h_2=\dfrac{h_1V_2}{V_1}\\\\h_2=\dfrac{25\times 3100}{3970}\\h_2=19.52\ cm

So, the height of the smaller cone is 19.52 cm.

PLEASE HELP!
serg [7]

Hello from MrBillDoesMath!

Answer:

x = 30

Discussion:

Note: I ignored the * in f*(x)  as i don't know what it means. (If this is not what you intended, please indicate what * means)

f(x) = 2 sqrt(x-5) + 4          

f(x) = 14

=>

14 = 2 sqrt(x-5) + 4             => subtract 4 from both sides

14 -4 = 2 sqrt(x-5)               => divide both sides by 2

10/2 = sqrt(x-5)                   =>

5 = sqrt(x-5)                        => square both sides

5*5 = x-5                              => add 5 to both sides

5*5 + 5  = x

25 + 5 = x

x = 30

Thank you,

MrB

ciara is making a new outfit. She needs 2 1/2 yards of fabric for the shawl. She needs 1 7/8 yards of fabric for the dress. if s
lisov135 [29]
First find out the total amount you need for your fabric.
2 1/2 yards for the shawl1 7/8 yards for the dress
The total would be    2 4/8  + 1 7/8  = 4 1/8 yards
Since you already have 9/10 of a yard, just subtract from your total amount.
  3  90/80  +  72/80 = 3 18/80 = 3 9/40   *good to simplify*
She needs 3 9/40 yards more of fabric.
You already have 9/10 of fabric so you don't need to pay for it.You need to just pay for the 3 9/40 yards.
3 * 6.87 = 20.61(6.87/ 40) * 9 = 1.54575 
20.61 + 1.54575 = 22.15575 *round it*
You need $22.16 to make the dance outfit.
