Step-by-step explanation:
Arc length formula is

where x is radinas.
A semi circle has a radian measure of

The radius is half of the diameter, 12 so the radius is

So the arc length is

Area of semi circle is

where r is the radius.




Given that,
In <u>triangle TPQ, </u>
As it is given that, <u>RS || PQ</u>
So, it means
⇛∠TRS = ∠TPQ [ Corresponding angles ]
⇛ ∠TSR = ∠TPQ [ Corresponding angles ]

<u>Now, We know </u>
Area Ratio Theorem,
This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.





Multiply 120 by .7 then take the product and add it to 120.
5:2:3
5+2+3=10
If she has double of plum juice the ratio will be
10:4:6
10+4+6=20
So she can make 20 cups of fruit punch.
2.50$ is the better deal. If you times 0.70$ to 5 it is 3.5$ which is more expensive
