MArishka [77]

Answer:

There are 4 possible ways

Step-by-step explanation:

Data provided in the question:

Alex can hop in 1 steps, 2 steps, or 3 steps at a time.

From the above data it can be concluded that at a single maximum 3 steps can be run at a time

thus,

for running 3 steps at a time from the above data, we can have

with 1 step only : {1 , 1 , 1}

with 1 step first and 2 steps : {1 , 2}

with 2 steps first and then the 1 step: {2 , 1}

and 3 steps at once : {3}

thus, we have 4 possible ways to run up the stairs keeping the above condition.

The snow at my aunt winter house is up to 11/12 feet. A new storm added 7/2 feet what is the snow level now?

FinnZ [79.3K]

First make common denominators.

Multiply 6 to numerator and denominator of 7/2

7/2(6/6) = 42/12

Add the two fractions together.

42/12 + 11/12 = 53/12

Change the improper fraction into mixed fraction, and simplify if need be.

53/12 = 4 5/12

4 5/12 feet is your answer

hope this helps

Julio is paid 1.2 times his normal hourly rate for each hour he works over 31 hours in a week. Last week he worked 41 hours and

xxTIMURxx [149]

Let Julio's normal hour rate is $x .

So we have

$31x + (41-31)*1.2 x = 550.40
\\
31x +10*1.2x = 550.40
\\
31x+12x = 550.40
\\
43x= 550.40
\\
x = \frac{550.40}{43}=$12.80$

So Julio's hourly rate is $12.80.

And this is reasonable , since working 41 hours at a rate of $ 13 per hour is

$=41(10+3)=410+123=533$

is close to 550.40 .
