Answer:

im not sure if it can be a decimal tell me if it cant but if it can its 0.25

Step-by-step explanation:

0.25*8=2 2+3=5

and i get my answer by a little bit of trial and error. I knew that what ever i timed by 8 had to equal 2 in order for the +3 to get it to 5 and the only thing that you can times by 8 and get 2 is 0.25.

In abc above,what is the length of ad

Nezavi [6.7K]

Answer:

Step-by-step explanation:

First calculate BD using sine ratio in Δ BCD and the exact value

sin60° = $\frac{\sqrt{3} }{2}$ , thus

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{BD}{BC}$ = $\frac{BD}{12}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2BD = 12 $\sqrt{3}$ ( divide both sides by 2 )

BD = 6 $\sqrt{3}$

-----------------------------------------------------------

Calculate AD using the tangent ratio in Δ ABD and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , thus

tan30° = $\frac{opposite}{adjacent}$ = $\frac{AD}{BD}$ = $\frac{AD}{6\sqrt{3} }$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

$\sqrt{3}$ AD = 6 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

AD = 6 → B

What’s the volume of a con that is 2 ft tall and a radius of 1

sashaice [31]

Answer: $2.09ft^3$

Step-by-step explanation:

$Formula: V=\pi r^2 \frac{h}{3}$

Plug in your values.

$V=(3.14)(1ft)^2(\frac{2ft}{3})$

Square 1ft.

$V=(3.14)(1ft^2)(\frac{2ft}{3})$

Plug this into a calculator or do it manually.

$V=2.09ft^3$
