Answer:
45
Step-by-step explanation:
c^2*b
We know that c is 3, and b is 5, so we can substitute them in
3^2*5
Solve the exponent first
9*5
Multiply
45
Answer:
n = 6
Step-by-step explanation:
Two intersecting chords. The product of the parts of one chord is equal to the product of the parts of the other chord, that is
7(n + 4) = 5(n + 8) ← distribute parenthesis on both sides
7n + 28 = 5n + 40 ( subtract 5n from both sides )
2n + 28 = 40 ( subtract 28 from both sides )
2n = 12 ( divide both sides by 2 )
n = 6
Answer:
- <u><em>Option A. 64,500</em></u>
Explanation:
1. First, calculate the number of hits had during the month, by difference:
- 50,165 hits - 7,278 hits = 42,887 hits
2. Round the result to obtain an approximation = 43,000 hits
3. Multiply by the time that each lasted:
- 43,000 hits × 1.5 min/hit = 64,500 minutes.
Hence, the answer is the option A.
1week = 7days so
4weeks = 28 days
So 28 x 640 = 17920
1000grams = 1kg
17920 divide 1000 =17.92
Lee uses 17.92kg in those 4weeks
