This pattern is adding the next odd number, starting with 3. For example, we can use the first few numbers:
1 + 3 = 4
4 + 5 = 9
9 + 7 = 16
This means that when we reach 49, we have to add 17 into it to get the answer of 66.
The missing side length is approximately 99.84 m
1/4 of the list price was off, so $90 was 3/4 of the list price. (1 -1/4= 3/4).
We have an equation: 90/? = (3/4)/1
Cross multiply:
3/4*? = 90*1
⇒ ?= 90*1/(3/4)= 90*1* (4/3)= 120.
The list price was $120.
Hope this helps~
Answer:
Pedro hits 1471 times and Ricky hits 1195 times.
Step-by-step explanation:
Pedro has 276 more hits than Ricky.
So, p = r + 276 ....... (1)
And their total hits is equal to 2666.
p + r = 2666 ........ (2)
Now, substituting the value of p from equation (1) to equation (2) we get,
r + 276 + r = 2666
⇒ 2r = 2390
⇒ r = 1195
Hence, from equation (1) we get p = r + 276 = 1471.
Therefore, Pedro hits 1471 times and Ricky hits 1195 times. (Answer)
