x² = 249,64 - 28,09

Answer:

x = + 14.88 km

Step-by-step explanation:

Let's solve for x using the Pythagorean Theorem.

The length of the hypotenuse is 15.8 km; that of the shorter leg is 5.3 km.

Since a² + b² = c², we get:

(5.3 km)² + x² = (15.8 km)²

Solving for x², we obtain (15.8 km)² - (5.3 km)² = 249.64 km² - 28.09 km²

The last expression returns the value 221.55 km² for x²

Taking the square root of both sides, we get x = + 14.88 km

Answer:

(D) "...because he will not have to pay any interest on his purchases during the introductory APR period."

Step-by-step explanation:

There may be many reasons for John to choose one over the other depending on his future and planned usage patterns. However, answer the (D) is the only correct one in terms of stating a reason that is actually supported by the information in the question. Specifically, there is 0% APR for card B.

What's wrong with the other choices:

Choice A: incorrect statement re APR after intro period (is not 1%); B: incorrect statement re cash advance (is not 0%); C: statement is not supported by anything in the information given (it is an assumption, and is unlikely).

52/3 - 10
Convert both numbers into fractions.
52/3 - 10/1
Make sure they both have the same denominator
52/3 - 30/3
Now you can take the numerator and subtract it.
22/3
Now you simply simplify
7 1/3
So the answer is 7 1/3

Which term BEST describes the quadrilateral formed when line segments connect points A, B, C, and D?

NeX [460]

Answer:

The quadrilateral formed is a trapezoid

Step-by-step explanation:

In this case, it is necessary to know what points A, B, C, and D.

If the points are equal to the following coordinate points

A (-2, 1)

B (2, 1)

C (3, -2)

D (-3, -2)

As shown in the image the answer would be a trapezoid.

________________________________

The figure cannot be a square, a rhombus or a rectangle since by definition these are:

A square has all sides of equal length and all its right angles.

A rhombus is a parallelogram that has all sides of equal length and all its angles different from right angles.

A rectangle is a parallelogram that has all its right angles.

The figure that we obtain is neither a parallelogram nor does it have all its right angles.
