4. Lincoln began his speech, “Four score and seven years ago....” How many years is four score and seven? (Hint: A score is 20 years.) Can someone help me?​

Answers

Answer 1
87 years I think…. If a score is 20 years and four scores have passed you do 4x20 = 80. 80 plus the seven 80+7 = 87

Ania scored a total of 120 points this season so far and averaged 15 points a game. How many games has she played?​

Answers

She played 8 games. Since she earned a total of 120 points and 15 points per game you would divide 120/15=8

Answer: Ania has played 8 games.

Step-by-step explanation:

Divide 120 by 15. 120 / 15 ?

15 fits into 120 exactly 8 times.

So , 120 - 120 = 0.

Patrick's gross earnings for the week are $1592.45. His deductions comprise 26% of his total compensation. What is his net pay? Enter your answer rounded to the nearest cent, such as: $4253.64.

Answers

Pretty sure it’s $1560.60

Patrick's net income will be equal to $1178.41.

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Patrick's gross earnings for the week are $1592.45. His deductions comprise 26% of his total compensation.

Patrick's net income will be calculated as below:-

26% of $1592.45 = 1592.45 x ( 26 / 100 ) = 414.037

Subtract the deduction from the gross amount:-

Net income = 1592.45 - 414.037 = $1178.41

Therefore, Patrick's net income will be equal to $1178.41.
