A store sells a box of pencils for $3. Each box contains 24 pencils. How much will it cost a teacher to buy pencils

alex41 [277]

Answer:

Step-by-step explanation:

This is for one pencil to each student. Since each box is $3, and she has 25 students, you would figure out how many students are left out with one box, and since you only have one left, you only need one more box. That would mean two boxes, so $3x2= $6

You bike 11.2 miles in 1.4 hours at a steady rate. What equation represents the proportional relationship between the x hour you

Elis [28]

Answer:

$\frac{x}{y}=8$

Step-by-step explanation:

Let the time for which i bike is = x hours

Let the distance traveled in x hours = y miles

Ratio of distance and time will be = x : y

I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112

then the ratio of distance and time will be same in both the cases

So equation will be

$\frac{x}{y}=\frac{14}{112}$

$\frac{x}{y}=8$

Therefore, equation representing the proportional relationship will be

$\frac{x}{y}=8$

Need help on this!! 10 points!!

Reptile [31]

Answer:

Step-by-step explanation:

The change of base formula is

$log_a(b)=\frac{log_{10}b}{log_{10}a}$ so filling in our given:

$log_{13}}(297)=\frac{log_{10}297}{log_{10}13}$ (Note: you do not have to put the base of 10 in the change of base formula because the "normal" base for a log is 10 and that is how your calculator figures it.)

Do this on your calculator to get

$\frac{log297}{log13}=2.2198$ Not sure how many decimal places you needed!
