A = Andrew
S = Sister
A : S
2 : 3
2 + 3 = 5
250 ÷ 5 = 50
2 × 50 = 100
3 × 50 = 150
∴ A : S
100 : 150
So Andrew keeps £100 of his salary every week.
Of this, he saves 12%:
100 × (12 ÷ 100) = 12
So he saves £12 every week
360 ÷ 12 = 30
∴ it will take him 30 weeks to save £360.
Answer:
The distance of ship B from the Harbor is 32.26 miles
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.
I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

.... flip both fractions.
.... multiply both sides by 22


So the distance of ship B from the Harbor is 32.26 miles

Answer: Choice D</h3>
Explanation:
The first term has its exponents add to 1+2 = 3
The second term has its exponents add to 1+1 = 2
The third term can be written as -2x^0y^0, and those exponents add to 0
The sums count down: 3, 2, 0
So standard form means we write the terms with the largest degree sums first, then second largest and so on.
