Mario makes 6 free throw shots out of his first 10 attempts. what is the least number of consecutive shots mario must make to

increase his overall percentage from 60% to at least 70%?

1 shot

4 shots

10 shots

14 shots

4 shots

Step-by-step explanation:

Currently he makes: 6/10 = 60%

Letting x = additional free throws to make 70%, we can apply

(6 + x) / (10 + x) = 70%

Solving for x:

(6 + x) / (10 + x) = 7/10

cross multiply:

60 + 10x = 70 + 7x

3x = 10

x = 3 1/3

Since he can not make 1/3 of a shot, the least number of consecutive shots to get to 70% would be 4.

B. 4 Shots

Step-by-step explanation:

Mario makes 6 free throw shots out of his first 10 attempts. What is the least number of consecutive shots Mario must make to increase his overall percentage from 60% to at least 70%?

1 shot

4 shots

10 shots

14 shots

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
