Answer:
-23/4 ft
Step-by-step explanation:
Combine -2 1/2 ft with -3 1/4 ft. The result will be -5 3/4 ft, or -23/4 ft.
1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
Answer:
x ≤ 6.12
Step-by-step explanation:
If the cost of 1 hamburger in a restaurant is $0.49, the amount of hamburger $3 can buy is expressed as shown
.
$0.49 = 1
$3 ≤ x (since you have maximum of $3 to spend. It cant be more than that)
cross multiply to find the expression for x.
$0.49 * x ≤ $3 * 1
$0.49x ≤ $3
Divide both sides by $0.49
$0.49x/$0.49 ≤ $3/$0.49
x ≤ $3/$0.49
x ≤ 6.12
The number of hamburgers you can buy is represented by the inequality x ≤ 6.12
After two years with the interest compounded annually the amount would be $1,060.90.
After two years with the interest compounded monthly the amount would be $1,061.76.
After two years with the interest compounded quarterly the amount would be $1,061.60.
After two years with the interest compounded semiannually the amount would be $1,061.36.
