Answer:
76%
Step-by-step explanation:
Because there were 50 people present at his birthday, 50 will be our denominator. Only 38 people chose to eat it so that will be our numerator. 38 out of 50 people chose to have chocolate cake:
would be the fraction.
50x2 would be 100 and we need 100 to make it a percentage. We will multiply the bottom and the top by 2.
x 2 = 76/100 = 76%
76% of the people at the party picked chocolate cake.
Answer:
33.2444...
Step-by-step explanation:
The rate of charge is $22 per 90 feet, so first we need to find out how many feet the perimeter takes up. To find the perimeter, we distribute 2 to both sides will adding them. 2(20 + 38) The 2 is there since that only covers 2 out of the 4 lines of a rectangle. Now we do the math as mentioned. 2(30 + 38)
The answer to that would be 136 feet. Now to figure out the cost, we use 22 to see how many 90's can fit into 136 so we can get the rate needed, which is (1.511111..). Thats how many times 90 goes into it, and for every 90 feet, we pay $22, So now we multiply 1.51111 by 22 to get the answer. (33.244444)
