Answer:
6.5
Step-by-step explanation:
9x=58.50
This equation is telling us that she bought 9 tickets at x cost each and the total was 58.50
Simplify the equation to solve for x. Divide by 9 on both sides.
⁹ˣ/₉ = ⁵⁸·⁵⁰/⁹
x=6.5
Answer:
5.2
Step-by-step explanation:
√27 = 5.1962 (5s.f.) = 5.2 (2s.f.)
F = 18 ft.
The law of cosines states
c² = a² + b² - 2ab cos C
Using our information, we have
c² = 23² + 16² - 2(23)(16)cos 52
c² = 529 + 256 - 736cos 52
c² = 785 - 736cos 52
c² = 331.8732
Taking the square root of both sides, we have
c = √331.8732 = 18.22 ≈ 18
For this question, let's move the decimal number 2 spaces to the right. 2.16-->216 You need 21 ten rods and 6 cubes. Why: I wouldn't do 2 hundred flats because 2 isn't divisible by 3. Put the ten rods into 3 equal group, then do the same with the cubes. You should end up with 7 in each group since 21 divided by 3 is 7. You should also end up with 2 cubes in each group. So in one group you have 72. Now move the decimal back to where it came from, 2 spaces to the left. Now you have 0.72
