Harshini rode her bicycle 13.76 kilometers on Monday, 9.8 kilometers on Wednesday, and 16.415 kilometers on Friday.
rusak2 [61]

Answer:

The last method (Round 13.76 to 14, round 9.8 to 10, and round 16.415 to 16; since 14 + 10 + 16 = 40 and 40 is close to 39.975, her  answer is reasonable.)

Step-by-step explanation:

Option 1 is unreasonable because removing the decimal points just changes the whole problem and claims that Harshini rode her bike 1376 kilometers on Monday and etc., which she did not. Option 2 is unreasonable because not all the numbers are near 20 and should be rounded to their nearest whole numbers instead to find a more accurate estimate. Option 3 is unreasonable for the same reason as option 2, the numbers should be rounded to their nearest whole numbers instead to find a more accurate estimate. Option 4 is reasonable because the numbers are rounded to the nearest whole numbers which makes the estimate more accurate.

Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the \$j$jdollar sign, j fare a
Galina-37 [17]

Answer:

\$ (\frac{j+15}{3} )

Step-by-step explanation:

There were three friends and the total fare was $j

Each of the friends pays \$ (\frac{j}{3} ) for their cab fare.

Since Angela also paid a $5 Tip

Total Amount Paid by Angela = Share of cab fare + Tip

\$ (\frac{j}{3} ) + \$5

We can simplify this further by taking the LCM.

\$ (\frac{j}{3} ) + \$5=\$ (\frac{j+15}{3} )

The total amount paid by Angela therefore is :\$ (\frac{j+15}{3} )

In Lixue’s garden, the green pepper plants grew 5 inches in 34 month. At this rate, how many feet can they grow in one month? (L
beks73 [17]

Answer:

<h2>0.15 inches per month</h2>

Step-by-step explanation:

step one:

This problem is focused on the growth rate of a plant.

given data

the plants grow 5 inches in 34 months

and also that 1 month= 4 weeks

step two:

We can still say that

if 34 months see a growth of 5 inches

then 1 months will be X inches

cross multiply we have

X= 5/32 inches

step three:

converting this number to decimal we have

X= 0.15 inches per month

Therefore the growth rate would be

0.15 inches per month
