Answer:

1 1/4

Step-by-step explanation:

34÷710=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

34×107=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

3×104×7=3028

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 30 and 28 using

GCF(30,28) = 2

30÷228÷2=1514

The fraction

1514

is the same as

15÷14

Convert to a mixed number using

long division for 15 ÷ 14 = 1R1, so

1514=1114

Therefore:

34÷710=1 1/4

A user’s password to access a computer system consists of 3 letters followed by 2 digits. How many different passwords are possi
Vesnalui [34]

Answer:

26*26*26 = 17576 ways to select 3 letters

10*10= 100 ways to select 2 numbers

So then the total number of ways are:

26^3 *10^2 = 1757600 possible ways

Step-by-step explanation:

For this case we assume that we have 26 letters from A to Z and 10 numbers from 0 to 9 .

And we want to calculate the number of possible passwords possible if the password consists of 3 letters followed by 2 digits.

And for this case we can use the multiplication principle of combinatories, since we don't have any restriction about the letters of the numbers we can have repetition of letters or numbers.

For the number of possible letters:

26*26*26 = 17576 ways to select 3 letters

10*10= 100 ways to select 2 numbers

So then the total number of ways are:

26^3 *10^2 = 1757600 possible ways

Find Percent of a Number - Instruction - Level F
dimaraw [331]

Answer:

Sierra's team has a greater percent of left-handed batters.

25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.

Step-by-step explanation:

Sierra: 7/28 = 1/4

1/4 written as a percentage is 25%

Aubrey: 5/25 = 1/5

1/5 written as a percentage is 20%

25% is greater than 20%, so Sierra's team has a greater percent of left-handed batters.

25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.

Hope this helps ;)
