Answer:
the answer is the first one
Step-by-step explanation:
39.99 rounded up is 40.00
19.99 rounded up is 20.00
40.00*0.05 = 2, 40-2 = 38
20.00*0.15 = 3, 20-3 = 17*.05 = 0.85, 17-0.85 = 16.15
38+16.15 = 54.15
Answer:age of the man: 75 age of the woman:25
Step-by-step explanation:
First, We need to define the variables
x: age of the man
y: age of the woman
at the first time he has three times her age
x=3y (1)
in 25 years time
(x+25)=2(y+25) (2)
we clear the equation
X+25=2y+50
X=2y+25
we substitute in the (1) equation:
2y+25=3y
y=25
x=3*25=75
Answer:
101 m^3
Step-by-step explanation:
v = π * r^2 * h/3
= π * 4^2 * 6/3
v= 100.53 m^3
v= 101 m^3 to the nearest cubic meter
Answers: 18
Square inches
Explanation: A=1/2bh
A=1/2*4.5*8=18
And area is in units squared and the units are inches in this problem so it would be 18 inches squared
I think the answer is A. If you use the values for each variable approximately a(2.2) or b(8.5) or c(3.7). You will find that the only way to get a number greater than the value of "a" is to have a value that is fairly high. Thus, if you substitute my values into the equation you will see that the answer is greater than "a". Hope this helped :))
