Answer: 5.1961
Step-by-step explanation: I believe you would use the Pythagorean’s theorem, since it’s a problem about a ramp, always draw pictures for word problems. So you would plug your numbers in the formula and solve. 3 squared plus B squared (that’s what we are trying to find so its a variable) equals 6 squared. Then you square and it becomes 9 + b2= 36, subtract 9 on both sides, b2=27, then square root on both sides to get 5.1961. Hopefully that’s right. :)
$78.68 because 93.60+%20-%30 is $93.60+18.72-33.69=78.68
Answer:
The answer is 8 rows.
Step-by-step explanation:
It is given that each row contain only 5 circles and there are 40 circles in the array. In order to find the numbers of row, you have to divide the total of circle by the number of circle in each row :
total = 40 circle
each row = 5 circle
5 circles = 1 row
40 circles = x row
x = 40/5
= 8 rows
Answer:
this means that she had spent 196.44 dollars
Step-by-step explanation:
109.32 (started off with)
-87.12(how much she ended up with)
we know that she went over cause she ended up with a negative so you just add how much she went over and how much she had orgiginally had
Quadratic equation x=-b+-√b²-4ac
---------------- x=ax²+bx+c
2a
a song to remember is : x equals opposite b plus or minus square root b squared minus 4ac all over 2a
-hoped it helped good luck
