Answer:
2:3
Step-by-step explanation:
for every 2 girls there is 3 boys so the ratio is 2:3
If Jim drives 25miles/hr and he is 30 miles away you would need to solve for the number of hours it would take to get there. So, you can set up a proportion: 25miles/1hr=30miles/xhr cross multiply to get 25x=30 divide both sides by 25 and your answer is 1.2 hours.
Given triangle is a right angle triangle so we are allowed to use trigonometric formulas.
We want to find Hypotenuse using angle A and base 7 cm
so right choice is to use cosine





Hence value of side AB is approx 7.72 cm.
Robert must work a minimum of 40 hours this week. To solve this, you set up an equation. 3.50x+25=165. Subtract 25 from both sides. 3.50=140.
Divide both sides by 3.5, which equals 40.
