Total cost = 62 + (6% of 62) + (20% of 62)
- Find 6% of 62:
1% = 62 / 100 = 0.62
0.62 x 6 = 3.72
- Find 20% of 62:
10% = 6.2
6.2 x 2 = 12.4
Add everything together:
62 + 12.4 + 3.72 = 78.12
The total cost was $78.12
Step-by-step explanation:
seems to be multiplication, because the differences between the numbers change.
so, let's find the factor.
2 × f = 5
f = 5/2
5 × f = 5 × 5/2 = 25/2
ok, the factor 5/2 is confirmed.
a1 = 2
a2 = a1 × 5/2 = 2 × 5/2 = 10/2 = 5
a3 = a2 × 5/2 = a1 × 5/2 × 5/2 = 2 × 5/2 × 5/2 = 25/2
an = an-1 × 5/2 = a1 × (5/2)^(n-1) = 2 × (5/2)^(n-1)
a9 = 2 × (5/2)⁸ = 2 × 390,625/256 =
= 390,625/128 = 3,051.7578125
Answer:
1. 9
2. 6√(2)/8.49
3. √(12)/3.46
4. √(50)/7.07
5. 1584
Step-by-step explanation:
Use pythagorean theorem for all of these triangles which is a^2+b^2 = c^2, for the problems with writing, just break it down and draw out a triangle and solve it from there and plug in the right numbers and solve
Answer:
x = 0, 7
Step-by-step explanation:
Step 1: Write out equation
x² - 7x = 0
Step 2: Factor out <em>x</em>
x(x - 7) = 0
Step 3: Find roots
x = 0
x - 7 = 0
x = 7
