Answer:

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

Hope this helped :)

Tan145+tan85/1-tan145*tan85 as asingle funciton

Minchanka [31]

Answer:

Step-by-step explanation:

Tan 145 = - 0.7002

Tan 85 = 11.43

Tan 145 + tan 85 = 10.7298

1 - tan(145)* tan(85) = 9.003

(Tan(145) + Tan(85)) / (9.003)

= 10.73 / 9.003

= 1.1918

I misread the question. If you mean

(Tan145+tan85) /1-tan145*tan85 (brackets are really important here)

then the answer is

Tan(145 + 85)

= Tan(230)

= 1.1918

A six-sided Fair number cubis rolled 100 times as part of an experiment. The frequency of the role of the number 3 is 20. W hich

Anastasy [175]

Answer:

The Theoretical probability is 1/6.

The experimental probability is 1/5

Step-by-step explanation:

Given

Rolls: 100

Outcome of 3 : 20

Required

Which of the options is true (See attachment for options)

From the attachment, we understand that the question requires that we calculate the experimental and theoretical probability.

The experimental probability (E) is calculated as thus:

$E = \frac{Outcomes}{Total\ Rolls}$

$E = \frac{20}{100}$

$E = \frac{1}{5}$

The theoretical probability (T) is calculated as thus:

A cube has 6 faces, one of which is the face 3.

So, T is:

$T = \frac{n(face\ 3)}{n(Total)}$

$T = \frac{1}{6}$

Hence, C is true

What is the amount sales tax on a suit priced at $3,129 if the sales tax rate is 4%?

svp [43]

To find the tax = $3129 × 4% = $125.16.
The final price = $3129 + $125.16 = $3254.16.

Hope this helps
