Answer:
It’s the 2nd,3rd,and 4th
Step-by-step explanation:
I just took the quiz
The equation is y = 1/2 x + 13, where x is the number of days, and y is the length of the barrier
1. Area of a circle is pi x R^2
Area = 3.14 x 18^2
Area = 3.14 x 324= 1017.36 sq. In.
The blade covers 122 out of 360 degrees.
1017.36 x 122/360 = 345 square inches.
2.
Like above.
Area =3.14 x 75^2 = 17,662.5 square feet
17662.5 x 80/360 = 3,925 square feet.
Answer: 5 feet of wood for 2.23
because the unit rate for each foot of wood is .45 compared to getting 6 feet for 2.95. 2.23 plus .43 (the cost for one foot) would be 2.63 making the wood much cheaper than the 6 foot option.
The answer is D. m<M'N'O'=m<MNO
Hope I helped?
