Answer:

39/30= 13/10

Step-by-step explanation:

You would need to make all numbers have a common denominator. The least common denominator for them is 30. So multiply the 1/6 by 5. the 4/5 by 6 and the 2/3 by 10. And the answer will come out to be a mixed number.

Step-by-step explanation:

(a)In the age group 58 and above:

Number in favor of building the skateboard ramps=6

Number opposed to building the skateboard ramps=44
Total = 50

Percentage of those in favor = $\frac{6}{50}X100 =12\%$

(b)In the age group 18-37

Number in favor of building the skateboard ramps=40

Number opposed to building the skateboard ramps=10
Total = 50

Percentage of those opposed to it = $\frac{10}{50}X100 =20\%$

(c)

Total Number of those in favor of building the skateboard ramps=73

Find the sum of 997 + 992 + 987 +...+ 257 +252

Vikentia [17]

Answer:

93,675

Step-by-step explanation:

We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.

The number of terms in the sequence (n) can be found from the formula for the n-th term:

an = a1 +d(n -1)

(an -an)/d +1 = n

(252 -997)/(-5) +1 = n = 150

The sum of these terms is the average of the first and last terms, multiplied by the number of terms:

S150 = (997 +252)/2·150 = 93,675

The sequence sum is 93,675.
