The first five numbers were 7,14,8,32,and 14. What was the average (mean) of these numbers?​

15

Step-by-step explanation:

1. add all the numbers:

7+14+8+32 + 14 = 75

2. then divide 75 by the amount of numbers you have. (in this case you have 5 numbers)

75/5 = 15

so your final answer is 15

hope this helped ^^

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
