Answer:
b=9
Step-by-step explanation:
18/24=3/4
3/4=b/12
cross product
4*b=3*12
4b=36
b=36/4
b=9
Answer: 2/5
Step-by-step explanation: The total number of letters available to choose from is 10. You want to know the probability of 4 of those 10. So you divide 4/10. When you simplify that fraction it becomes 2/5.
If you're using log:
Swap both sides: 1100 · 1.7^n = 7000
Divide both sides by 1100: 1.7^n = 70/11
Concert decimal to a fraction: (17/10)^n = 70/10
Take the log of both sides. (Put 17/10 into the subscript of log like the picture shows)
The answer is the decimal.
Answer:
Step-by-step explanation:
Area = 1/2(b×h)
b = 18, h = 8
Area = 1/2(18×8)
Area = 18 × 4
Area = 72 square inches
