Answer:
87.92
Step-by-step explanation:
3.14(a² + ab) where a = 4 and b = 3
Plug the given numbers into the appropriate values. Remember to follow PEMDAS.
3.14((4)² + (4)(3))
3.14(16 + 12)
3.14(28)
87.92
Answer:
(b)
Step-by-step explanation:
The hundredths place is immediately to the left of the thousandths place. In our base-10 number system, moving a digit to the left one place increases its value by a factor of 10.
The value of 7 in the hundredths place is 10 times the value of 7 in the thousandths place.
=50-(50*30%)
=50-(50*0.30)
=50-15
=$35
the new cost would be $35
If you would like to solve the equation k / 2 + 9 = 30, you can calculate this using the following steps:
k / 2 + 9 = 30
k / 2 = 30 - 9
k / 2 = 21 /*2
k = 21 * 2
k = 42
The result is 42.
