Answer:

0.1 hours to the nearest tenth (0.125 hours exact)

Step-by-step explanation:

For this problem, we simply need to do a conversion to find the length of time.

We are given the rate 40 miles per hour, and the distance of 5 miles. We simply need to know the amount of time.

5 miles * (1 hour per 40 miles) = 1 hour / 8

Note, the distance unit cancels out.

So, to travel 5 miles it will take 1/8 of an hour.

1/8 as a decimal is equal to 0.125. The answer rounded to the nearest tenth would be 0.1 hours, since the 2 rounds down.

Cheers.

Find the Sum of the Odd Integers between 140 and 204

Scorpion4ik [409]

Answer: 5504

Step-by-step explanation:

This involves us finding the sum of all odd integers from 141 to 203.

We can interpret this as an arithmetic sequence with first term 141 and common difference 2.

This sequence has $\frac{203-141}{2}+1=32$ terms.

So, the sum is:

$32\left(\frac{141+203}{2} \right)=\boxed{5504}$

Grace [21]

Answer:

After 6 weeks Rosa has saved $490.

2. Therefore, to solve this problem you only need to substitute 6 weeks (or $x=6$ ) into the given function, as following:

$f(x)=250+40x\\f(6)=250+40(6)=490$

3. The result is $490.
