41
Step-by-step explanation:
f(x) = 5x - 4
You have to replace 9 to every position x is in.
f(9) = 5×9 - 4
f(9) = 45 - 4
f(9) = 41
Have a good day!
Answer:
<em>37%</em>
Step-by-step explanation:
Add up the percentages and subtract them by 1.00:
- 35% & 28% = 0.35 & 0.28
- 0.35 + 0.28 = 0.63
- 1.00 - 0.63 = 0.37
- 0.37 = 37%
Good luck! :)
Answer:
The stack is 4½ inches tall.
Step-by-step explanation:
If both books are the same thickness, you are adding 2¼ + 2¼. This means that it will be 4 and two quarters. 2/4 is the same as 1/2, so simplifying gives you 4½.
area (pool)=area (rectangle) - area (triangle)
1) we calculate the area of the rectangle:
area (rectangle)=lenght x width
area (rectangle)=36 ft x 20 ft=720 ft².
2) we calculate the area of the triangle:
area (triangle)=(base x height) / 2
area (triangle)=(6 ft x 5 ft) / 2=15 ft².
3) we calculate the area of this pool:
area (pool)=720 ft²-15 ft²=705 ft²
Answer: the area of the pool is 705 ft².
