Step-by-step explanation:

\sin(x)  =  \frac{8}{10}  \\ x = 53.13

\sin(53.13)  =  \frac{4}{j}  \\ j =  \frac{4}{ \sin(53.13) }  =    \frac{4}{0.8}  = 5

Hey there!

I'm thinking B because it just makes the most sense reading it aloud. Quick tip though when there's a question like this just read the paragraph or sentences with all the possibilities in the blanks and you can kind of just tell which one it is by the way it sounds, you know?

Hope I helped, lemme know if I'm correct please! Have a spectacular day!

If 2/3 ton of gravel covers 3/4 of a driveway, how many tons of gravel are required to cover the entire driveway? (1 point) Ques
r-ruslan [8.4K]

Answer:

If 2/3 ton of gravel covers 3/4 of a driveway, you need to divide 2/3 divided by 3 to find how much is needed for 1/4 of the driveway. So first step:

1. 2/3 divided by 3 = 2/3 * 1/3. So 2/9.

2. Add 2/3 plus 2/9= 8/9 ton of gravel to cover the whole driveway.

- First find the area of the whole circle

The equation is :

πr^2

Substitute the radius in:

π(5)^2

Solve:

Area of full circle = 25π

(Note : leave this answer in terms of 'pi' so it is easier to handle

Next, find the area of the sector

The equation for this is:

(angle/360) x πr^2

Substitute the values in:

(80/360) x π(5)^2

Solve :

Area of sector = (50/9)π

Now, find the area of the triangle:

1/2 absinC

Substitute the values in:

1/2(5)(5) x sin(80) = 12.31009691

Subtract this answer from the area of the sector

Answer = 5.14319607

Subtract this from the area of the whole circle

Answer = 73.39662073

To the nearest tenth, that would be 73.4 cm^2

Have A Nice Day ❤
