Answer:
6. it is a square because all of the outer sides are equal
3. perpendicular because the slopes are reciprocals of eachother and the lines would form 90 degree angles
After 1 year, the couple will have a total of $2170.00 into their account.
Let us represent number of one person tubes rented by x and, number of cooler tubes rented by y As per the situation, total tubes are 15, hence x + y = 15 equation 1 Also, total expenditure on tubes is $270, therefore 20x + 12.5y = 270 equation 2 Linear equation written above, equation 1 and equation 2 represent given situation. Now, let us solve these equations to find number of tubes rented Multiplying equation 1 by 20 and subtracting equation 2 from it, we get 20x + 20y - 20x -12.5y = 300 - 270 7.5y = 30 y = 4 and from equation 1, x + 4 = 15 gives, x = 11 Therefore, number of person tubes = 11, number of cooler tubes = 4
Answer:
The distance, in feet, from the ground to the ladder is 12 feet.
Step-by-step explanation:
To answer this question, we must use the Pythagorean Theorem- a^2+b^2=c^2. C is the hypotenuse, and a and b are legs.
We have: 5^2+b^2=13^2
Simplifying: 25+b^2=169
Subtracting 25 from both sides: b^2=144
B=12.
Answer:
3
y=3x
4 hours
Step-by-step explanation:
15 dollars in one hour plus 5 as tip makes the ratio afterwards 15\5 which equals 3. 65 dollars - 5 equals 60, which divided by 15 = 4 hours.
