This is how you solve it; but first of all convert the percent into a decimal;55%= 0.55
0.55x = 164 (divide by 0.55 on both sides)
x = 164/0.55
x = 298.18 (rounded to the nearest hundredth)
so 164 is 55% of 298.18(rounded)
I believe it is (3*4*4*4)/16=12
hopefully its right and it helped!
Answer:
15 feet
Step-by-step explanation:
525 = ½(30+40)h
525 = 35h
h = 525/35
h = 15 feet
Step-by-step explanation:
Determine whether a number is a solution to an equation.
Substitute the number for the variable in the equation.
Simplify the expressions on both sides of the equation.
Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.
Hoped that helped:P
Answer:
1) f(3) means the temperature after 3 seconds
2) f(3) = 22 + 1.3(3) = 25.9
Temperature after 3 seconds is 25.9°C
3) f(t) = 35 means after t seconds, temperature was 35°C
4) 35 = 22 + 1.3t
1.3t = 13
t = 10 seconds
