You start driving north for 3 miles, turn right, and drive east for another 4 miles. At the end of driving, what is your straight line distance from your starting point?

Answers

Answer 1

Answer:

The straight line distance is 5 miles from starting point.

Step-by-step explanation:

Driving 3 miles north and 4 miles east and then the straight line distance will form a right angled triangle.

Where;

One leg = a = 3 miles

Other leg = b = 4 miles

Hypotenuse = c

Using Pythagoras theorem;

$a^2+b^2=c^2\n(3)^2+(4)^2=c^2\n9+16=c^2\nc^2=25$

Taking square root on both sides

$√(c^2)=√(25)\nc=5$

The straight line distance is 5 miles from starting point.

Answer 2

Answer:

Answer:

Step-by-step explanation:

3[2]+4[2]=c[2]

9+16=c[2]

$√(25)$ =5

8:4 6:4 8:2 6:3 biggest ratio

Answers

Easy, make the ratios as a decimal. 8:4=2, 6:4=1.5, 8:2=4, and 6:3=2. Now, we have 2, 1.5, and 4, and 2. We can eliminate 8:4 and 6:3 since they are the same ratios, 1.5 equals 1.50, 4=4. Ask your self. Is 1.50 greater than 4? Well your answer is no. 4 is greater than 1.50. So, the biggest ratio is 8:2

8:2 is the biggest ratio, because if you reduce each ratio to the smallest ratio 4:1 is the biggest. 8:4 = 2:1... 6:4 = 3:2... 8:2 = 4:1... 6:3= 2:1...

Karl bought 3 1/2 gallons of milk that cost $2.70 per gallon.What was the total cost of the milk?

Answers

The total cost of milk purchased is the product of the cost per gallon and the number of gallons purchased which is $9.45

Given the Parameters :

Cost per gallon = $2.70

Number of gallons purchased = 3.5 gallons

Total cost of milk purchased = Cost per gallon × number of gallons purchased

Total cost of milk purchased = $2.70 × 3.5 = $9.45

Therefore, the total cost of milk purchased by Karl ls $9.45
