Find the area of the triangle. Round to the nearest tenth.

Mathematics
1 answer:
Fiesta28 [93]2 years ago
5 0

Answer: 130

Step-by-step explanation:

Find the height of the triangle by using the pythagorean theorem

So the height is sqrt(100 - 25) = 5sqrt(3)

The area of the triangle is 30 * 5sqrt(3) / 2 = 75sqrt(3) = 129.9 = 130

There's one piece of information missing from the question, so
in order to completely calculate the answer, we must assume the
missing number.

We have no information that helps us calculate the probability
that you will eat the first jelly bean.  So we'll have to assume that
you will definitely eat it, no matter what color it is.  The probability is 1 .

-- You start out with  (2 + 4 + 8 + 6) = 20 jelly beans in the package.
    8 of them are purple.

-- If you close your eyes and pull one out of the package, then the
probability that it will be purple is
                                                  8 / 20 .

-- You definitely eat it.  The probability of this event is 1 .

-- Now there are  19  jelly beans left in the package.
   6 of them are blue.

-- The probability of picking a blue one out of the package without peaking is

                             6 / 19 .

-- The probability of all three of these events happening is

                       (8/20) · (1) · (6/19)

                   =  (8 · 1 · 6) / (20 ·19)

                   =      48 / 380 

                   =  12/95  =  0.1263...  =  12.63...%  (rounded)

What is the number of times a base is multiplied by its self indicated by an exponent
lozanna [386]

The question is worded a bit strangely (in my opinion anyway), but I think your teacher wants you to describe how exponents work.

Let's say we had the expression 5^3

The base is 5 as its the bottom most value (think of something like the base of a tree or building). The exponent is 3.

The exponent of 3 tells the reader to multiply the base 5 by itself 3 times like so

5^3 = 5*5*5 = 125

With larger exponents, it becomes more tedious to write out all the repeated multiplications, which is why many calculators have an exponent button to save time.

State the value of the discriminant of -6x^2 +2x + 3 = 0
Dmitry [639]

Answer:

76

Step-by-step explanation:

recall that for a quadratic equation in the form

ax² + bx + c = 0, the discriminant is given by

discriminant, D = b²- 4ac

we are given the following:

-6x² + 2x + 3 = 0,

comparing this with the general equation above, it is clear that,

a = -6, b = 2 and c = 3,

substituting these into our equation for discriminant:

D = b²- 4ac

= 2² - 4(-6)(3)

= 4 + 72

= 76
