Answer:
Option C, Ryder owed his mom $2.50. He babysits his sister and makes $8.75
Step-by-step explanation:
<em>Since it starts at 0 and goes to -2.5, that means that he owes $2.50</em>
<em>Since it goes from -2.5 to 6.25, that means that he ears $8.75</em>
Answer: Option C, Ryder owed his mom $2.50. He babysits his sister and makes $8.75
Answer:
1) b
2)d
3)a
Step-by-step explanation:
1) count the number of different betwwen 2 cycles
2) take 5/160 time 8
3) take 12/9.6 then times 6.4
From 4 p.m to 8 p.m, there are 4 hours. Each hour is composed of 60 minutes. This means that the total number of minutes is equal to 240. Thus, we determine the ratio of her time in doing the homework by dividing 10 minutes by 240 minutes, giving us the answer of 10:240 equal to 1:24.
The sum of the given sequence is -6384.
<u>Step-by-step explanation:</u>
The given Arithmetic sequence is 14 + 8 + 2+ ... + ( 274) + (-280).
- The first term of the sequence = 14
- The last term of the sequence = -280
- The common difference ⇒ 14 - 8 = 6
<u>To find the number of terms in the sequence :</u>
The formula used is
where,
- n is the number of terms.
- is the late term which is -280.
- is the first term which is 14.
- d is the common difference which is 6.
Therefore,
⇒
⇒
⇒
⇒ n = 48, since n cannot be negative.
∴ The number of terms, n = 48.
<u>To find the sum of the arithmetic progression :</u>
The formula used is
where,
- S is the sum of the sequence.
- is the first term which is 14.
- is the late term which is -280.
Therefore,
⇒
⇒
⇒
∴ The sum of the given sequence is -6384.
