Find the length of the hypotenuse
34^2 + 27^2 = c^2
1156 + 729 = 1885
c^2 = 1885
sqrt(1885)
c = 43.42
Step-by-step explanation:
Variable x = total number of students enrolled
495 people at the dance - 7 teachers = 488 students
4/5 = 488/x
Step 1: cross multiply
4x = 2440
Step 2: isolate the variable (x) by dividing by 4
x = 2440 ÷ 4
Step 3: solve
x= 610 students total
D. 46. Add each number that 9 is being multiplied by.
Answer:
Step-by-step explanation:
Apparently, your system of equations is supposed to be ...
We can multiply the first equation by 2 and subtract the second equation:
2(4b -3h) -(5b -6h) = 2(64) -(44)
3b = 84
b = 28
Using the first equation, we can find the price of a hand towel:
4b -64 = 3h
h = (4/3)(b -16) . . . . . divide by 3 and factor out 4
h = (4/3)(28 -16) = 16
Bath towels cost $28 each, and hand towels cost $16 each.
The straight line distance is the square root of 74 ( which is APROXÍMATELY 8.602)
