Dayton is due north of Richmond, and Easton is 16 mi due east of Richmond. Dayton is 32 mi from Easton.How far apart are Dayton and Richmond? Round to the nearest tenth of a mile.


___ mi

Would you do 32^2-16^2 or 32^2+16^2

Answers

Answer 1
Answer: We need to use the Pythagorean Theorem, which states:

Hypotenuse^2 = (Leg_(1))^2 + (Leg_(2))^2

Look at the image I have attached.

Using what we know, we get:

32^2 = x^2 + 16^2\n\nx^2 = 32^2 - 16^2\n\nx^2 = 1024 - 256\n\nx^2 = 768\n\n\boxed{\bf{x=27.7~miles}}

You would have to do sqrt(32^2 - 16^2) to get the answer.

Your final answer is 27.7 miles.

Hope this helped! If you have any other questions or would like further explanation just let me know!! :)
Answer 2
Answer: It is 32^2 - 16^2

Draw a triangle

Richmond is right above of Dayton (North). The distance between them is a side of  the right triangle. You do not know this distance , it is the unknown side.

Dayton is 16 mi to the east. It is the other side of the right triangle.

The other known length is the hypotenuse of the right triangle, which is the distance from Easton to Dayton. It is 32 mi.

As per Pythagorean theorem, (Side_1)^2 = (hypotenuse)^2 - (Side_2)^2

If cos(2x-1)=sin(3x+6) the what is the value of x?

Answers

The value of x in expression cos(2x-1) = sin(3x+6) is 17.

cos(2x-1) = sin(3x+6)

let

a = 2x - 1

b = 3x + 6

Therefore,

cos a = sin b

Therefore,  a and b are complimentary.

What is complimentary angle?

Complimentary angles are angles that sum up to 90 degrees. Therefore,

2x - 1 + 3x + 6 = 90

2x + 3x - 1 + 6 = 90

5x + 5 = 90

5x = 90 - 5

5x = 85

x = 85 / 5

x = 17

2x - 1 + 3x + 6 = 90°
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85/5
x = 17°

Julia's great dane weighs 45 kgand Jake's chihuahua weighs 15 kg. How much bigger, as a percentage, is julia's dog?

Answers

Answer : The percentage will be, 200%

Step-by-step explanation :

First we have to calculate the excess weight.

Excess weight = 45 kg - 15 kg

Excess weight = 30 kg

Now we have to calculate the percentage of excess weight.

Percentage of excess weight = \frac{\text{Excess weight}}{\text{Weight of Jake's}}* 100

Percentage of excess weight = (30kg)/(15kg)* 100

Percentage of excess weight = 200 %

Therefore, the percentage will be, 200%
45kg-15kg=30kg Percentage: 30kg=0.3% Percentage =0.3%

The minimum fine for driving in excess of the speed limit is $25. An additional $6 is added to the minimum fine for each mile per hour (mph) in excess of the speedlimit. Rachel was issued a $103 fine for speeding in a 55-mph speed limit zone. For driving at what speed, inmph, was Rachel fined?

Answers

Let the excess speed limit be y.

According to your question,

25 + 6y = 103

6y = 103 - 25 = 78

y = 78/6 = 13

Thus, the excess speed was 13 mph.

Thus, speed of Rachel = 55 + 13 = 68mph

Thus, Rachel was driving at 68 mph.
