Find side x, giving your answer to 1 decimal place.<br> 810<br> 7 cm<br> 40°<br> Х
Andru [333]

Answer:

10.8

Step-by-step explanation:

By sine rule:

\frac{x}{ \sin 81 \degree}  =  \frac{7}{ \sin 40 \degree}  \\  \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree}   \\  \\ x =  \frac{7 \times0.9876883406 }{0.6427876097}  \\  \\ x =  \frac{6.91381838}{0.6427876097}  \\  \\ x = 10.755992 \\  \\ x  \approx 10.8

Help. IM SO LOST ON THIS! ;(
castortr0y [4]

Answer:

1. 4\frac{2}{3}

Step-by-step explanation:

For question 1, you need to know the ratio between the recipe and the amount in question.

So if in the recipe, it says it uses 3/4 cup of diced ham, and the question uses 1 cup of diced ham, you can divide 1 by 3/4 to get 4/3. This is how many times bigger the amount used in the question than the recipe.

Then it asks for how many cups of potatoes, to do this, you look at the recipe and how many potatoes it uses: 3.5 cups

To solve it then, you just do 3.5 x 4/3 to get 4\frac{2}{3} cups of potatoes

There's your answer.

How does 2π/4 simplify to π/4?
lana [24]
It doesn't
remember that
(x/g) times (y/z)=(x time y)/(g times z) so
2pi/4=(2 times pi)/(4 times 1) so
2pi/4=2/4 times pi/1=1/2 times pi/1=pi/2
