Find The Value Of X.2845x=[?]

Answers

Answer 1

Answer:

x=53

Step-by-step explanation:

One way to solve this problem is by using the Pythagorean Theorem.

This states that the square of one "leg" of the triangle plus the square of the other "leg" of the triangle would equal the square of the hypotenuse,  or the longest side of a triangle. Keep in mind that this only works for right triangles, where one angle  is exactly 90 degrees.

This formula can be written as: a^2 + b^2 =  c^2, where a and b are the legs and c is the hypotenuse.

So, for this problem, let a=28, and b=45.

This gives us: 28^2 + 45^2 = x^2

And we can simplify this to: 2809 = x^2

Taking the square root of both sides gives us the answer,  that x=53 units.

Hope this helps!

Step-by-step explanation:

Answer:

Step-by-step explanation:

The key word is increase.

People who don't have a cell phone will bid the price up until some of the people wanting a cell drop out of the bidding. Then only those willing to pay a higher price will be left to buy the cell at a much higher price than was initially thought to be the right price.

distance from Leicester to Derby is 50 miles.
a) At what time did he arrive in Leicester?
b) What was his average speed in mph?

Answers

Answer:

a. 12:10 pm

b. 40 mph

Step-by-step explanation:

Assuming you meant to type 1 ¹/₄ hours later.

a. First convert that to a improper fraction and then a decimal:

= 5/4

= 1.25 hours

1.25 hours in minutes is:

= 1.25 * 60

= 75 minutes

= 1 hour 15 minutes

The motorist left at 10:55.

= 1055 + 1 hour

= 11:55

Add 15 minutes:

= 12:10 pm

b. Speed = Distance / Time

= 50 / 1.25 hours

= 40 miles per hour
