a tennis player computes her win ratio by dividing the number of matches she has won by the total number of matches she has played. at the start of a weekend, her win ratio is exactly $0.500$. during the weekend, she plays four matches, winning three and losing one. at the end of the weekend, her win ratio is greater than $0.503$. what's the largest number of matches she could've won before the weekend began?

Answers

Answer 1

Using the ratio we know that before the weekend started, she could have won as many as 164 games.

What is the ratio?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0.

A proportion is an equation that sets two ratios at the same value.

For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.

So, let n be the number of victories so that:

n/2n = 1/2 and n+3/2n+4 > 503/1000

Now, cross multiply as follows:

1000n + 3000 > 1006n + 2012

n < 988/6 = 164 4/6 = 164 2/3

Therefore, using the ratio we know that before the weekend started, she could have won as many as 164 games.

Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the j$ fare among the 3 of them. Angela also paid a $5, tip. How much did Angela pay in total?

Answers

Answer:

[tex]$\frac{j}{3}+5$[/tex]

Step-by-step explanation:

It is given Angela shared a cab with her 2 friends.

Total number of people = 3

Answers

Answer:

dale is not correct

the correct angle is 30 degrees

Step-by-step explanation:

A cake is shaped like a circle

the total sum of angles in a circle is 360 degrees

If Dale and 2 friends share one fourth of a cake, the total angles they share = (1/4) X 360 = 90 degrees

If the 3 friends share the cake equally, the angles each get = (1/3) x 90 = 30 degrees

the correct angle is 30 degrees and not 45 degrees. Thus, Dale is wrong
