Mathematics

This segment creates a right triangle with the x and y axis. The two legs are 8 units and 6 units. Using the Pythagorean theorem, we know that 8^2+6^2=x^2, when x is the length of AB. 8^2+6^2=100. 
Therefore, 100=x^2
We can then take the square root of both sides to find that:
x=10.

What is the percent of change from 2000 to 200
Kamila [148]

Answer: 90% decrease

Step-by-step explanation: First determine whether the number is increasing or decreasing. Since it changes from 2,000 to 200, it's going down so it's decreasing.

Now to find the percent decrease, we divide the

amount of change by the original number.

The <em>amount of change</em> is the difference between the two numbers

which in this case is 2,000 - 200 and the original number is 2,000.

So we have \frac{2,000 - 200}{2,000}.

2,000 - 200 is 1,800.

So we're left with 1,800/2,000 and dividing

2,000 into 1,800 gives us 0.9.

Remember however that our problem is

asking for a <em>percent</em>, not a decimal.

So we need to write 0.9 as a percent and we can do

that by multiplying it by 100 and adding the percent sign.

So 0.9 becomes 90%.

So when a number changes from 2,000 to 200,

it has decreased by 90%.

A building 62 feet tall casts a shadow 21 meters long . At what angl is the sun shining on the building
yulyashka [42]

Answer:

71.3°

Step-by-step explanation:

A building 62 feet tall casts a shadow 21 meters long . At what angle is the sun shining on the building?

We solve this question using the Trigonometric function of Tangent

tan x = Opposite/Adjacent

Where

Opposite = 62ft

Adjacent = 21 ft

x = Angle

Hence,

tan x = 62/21

x = arc tan (62/21)

x = 71.288262125°

Approximately = 71.3°

Three families visited the local fair over a holiday weekend: the rawlins family spent $51 on admission for 2 children and 3 adu
Musya8 [376]

The matrix equation that can be solved to find all the respective costs is;

\left[\begin{array}{ccc}2&3&50\\4&6&100\\2&5&80\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = \left[\begin{array}{ccc}51\\90\\78\end{array}\right]

<h3>How to create matrix equations?</h3>

Let cost of admission for children be x.

Let cost of admission for adults be y.

Let cost of admission for carnival tickets be z.

Thus, we have the simultaneous equation as;

2x + 3y + 50z = 51

4x + 6y + 100z = 90

2x + 5y + 80z = 78

Thus, writing this in matrix form gives;

\left[\begin{array}{ccc}2&3&50\\4&6&100\\2&5&80\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = \left[\begin{array}{ccc}51\\90\\78\end{array}\right]
