Answer:

29.82

Step-by-step explanation:

First you have to do 127.8 divided by 60 to get how many miles he bikes a day, which is 2.13 Next, you multiply 2.13 by 2 weeks 2 weeks = 14 days So from then you do 2.13 x 14 which is 29.82 Chris bikes 29.82 miles in two weeks.

HELP ASAP ITS SO HARD! Kelsey did the following division problem. Her teacher says that the quotient she found is wrong. −2 5/6

SpyIntel [72]

Part A

Her steps were

$-2 \frac{5}{6} \div 1 \frac{1}{3}\\\\-\frac{17}{6} \div \frac{4}{3}\\\\-\frac{6}{17} \times \frac{3}{4}\\\\-\frac{6\times 3}{17\times4}\\\\-\frac{18}{68}\\\\-\frac{9}{34}\\\\$

Kelsey made a mistake on line 3. Note how the 17/6 flips to 6/17. This is not correct. You keep the first fraction the same, but you do flip the second fraction. This only applies when you divide two fractions.

The third step should look like $-\frac{17}{6}\times \frac{3}{4}$

=======================================================

Part B

Here's what she should have written

$-2 \frac{5}{6} \div 1 \frac{1}{3}\\\\-\frac{17}{6} \div \frac{4}{3}\\\\-\frac{17}{6} \times \frac{3}{4}\\\\-\frac{17\times 3}{6\times 4}\\\\-\frac{51}{24}\\\\-\frac{17}{8}\\\\$

If you want to convert that improper fraction to a mixed number, then you could do something like this

$-\frac{17}{8} = -\frac{16+1}{8}\\\\-\frac{17}{8} = -\frac{16}{8}-\frac{1}{8}\\\\-\frac{17}{8} = -2 \frac{1}{8}\\\\$

Or you could divide 17 over 8 using long division to get 2 remainder 1. The 2 is the quotient that goes to the left of the 1/8. The remainder of 1 is the numerator of 1/8.

QUESTION: Determine if the statement is true or false? if false give an counterexample.

Jobisdone [24]

Answer:

False

Step-by-step explanation:

Actual question is:

logf 4(3d) + log4 1 = log4 3d

Solution:

logf 4 + logf (3d) + 0 = log4 (3d)
logf 4 + logf (3d) = log4 (3d)

If we assume f = 4, then

log4 4 + log4 (3d) = log4 (3d)
log4 4 = 0

but log4 4 = 1

1 = 0 is impossible

Therefore the statement is False

Plz help..................

Misha Larkins [42]

The answer isn't A or B because those two are not factored. D is wrong because 8•8=64 not 16. So that leaves us with C (4•4=16).
