Answer:
10a
Step-by-step explanation:
10a is the same as 10 * a
product is multiplication
Since there are 20 students on the field trip. Then 20 is the 100% total. Thus, to find how many people love the museum, we can simply multiply the total number of people by the percentage of interest, namely 40%
20*0.4 = 8
So, 8 people love the museum.
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)
