8 0

Answer:

Step-by-step explanation:

Since we have not instructed to follow any kind of rule dividing, we can write in any form. Let's calculate it using fraction

$0.4:0.08=\frac{0.4}{0.08}$

We can multiply both the nominator and denominator with 100

$\frac{0.4}{0.08}=\frac{40}{8}=5$

The answer is 5.

We can also solve it as a division of fractions:

$\frac{4}{10} : \frac{8}{100} = \frac{4}{10} * \frac{100}{8} = \frac{10}{2} = 5$

Dave buys a baseball for $15 plus an 8% tax. Mel buys a football for $20 plus an 8$ tax. How much did each person pay?

-Dominant- [34]

Dave pays $15 and tax is $1.2 so dave spent a total of $16.20.

Mel pays $20 and tax is $1.6 so Mel spent a total of $21.60.

All you need to do is convert the percent to a decimal, so take 8 and divide by 100 and you get 0.08. then you need to multiply the cost by the tax so 15*0.08=1.2 then you just add tax to original amount 15+1.2=16.2

Find the largest prime divisor of 76^2 − 1.

saveliy_v [14]

Answer:

Step-by-step explanation:

This is a difference of squares and therefore can be written as (76-1)(76+1)=(75)(77).

So lets look at the factors....

75=3(25)=3(5)(5)

77=7(11)

The biggest prime factor is therefore 11.
