Answer:
Mrs. Salinas buys 4 ounces M&Ms and 6 ounces Peanuts.
Step-by-step explanation:
Given,
Total weight of the mixture = 10 pounds.
Total money Mrs. Salinas paid = $24.
We have to find out the weight of each M&Ms and peanuts.
Solution,
Let the weight of M&Ms be x.
And the weight of peanuts be y.
Since total weight of the mixture is 10 pounds.
So, we can frame it in equation as;
Again, Total money paid by Mrs. Salinas is the sum of weight of M&Ms multiplied by price for each ounce and weight of peanuts multiplied by price for each ounce.
So, we can frame it in equation as;
Now, multiplying equation 1 by 2, we get;
Now subtract equation 3 from equation 2, we get;
On substituting the value of x in equation 1, we get;
Hence Mrs. Salinas buys 4 ounces M&Ms and 6 ounces Peanuts.
Answer:
r ≈ 31.5 cm
Step-by-step explanation:
The arc of a circle is calculated as
arc = circumference of circle × fraction of circle

2πr × = 22
2πr × = 22 ( multiply both sides by 9 to clear the fraction )
2πr = 198 ( divide both sides by 2π )
r = ≈ 31.5 cm
