The system of equations below represents the measures of 2 angles created by the diagonal of a rectangle: x + y = 90 y =1/5 What
madreJ [45]

Answer:

The larger of the two angles is x, which is 75. y is the smaller angle at 15.

Step-by-step explanation:

In order to find these, we can use our solved value for y in the second equation to plug into the first equation. This method is called substitution.

x + y = 90

x + (1/5x) = 90

1.2x = 90

x = 75

Now we can plug that value into either equation to find y

y = 1/5x

y = 1/5(75)

y = 15

Find the area of the figure above. use 3.14 for π. do not round your answer
professor190 [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

This is the combination of three figures semi circle, rectangle and triangle.

We will find the area of each figure and will add them.

The radius of the circle is half of the diameter, so radius is 6.

Area of semi circle will be : \frac{1}{2} \times 3.14 \times 6^2

Area of semi circle is : 56.52

Area of rectangle is: length \times width

So, area of rectangle is:40\times 12=480

Area of triangle is : \frac{1}{2}\times base\times height

So, area of triangle is :\frac{1}{2} \times 12\times 5=30

Adding all these three areas, the area of above figure will be:

[tex]Area = 56.52+480+30

Hence Area is 566.52............... Answer

The 200th term of the arithmetic progression 10 97,94,91,.............is​
azamat

Answer:

-500

Step-by-step explanation:

Given sequence;

    97, 94, 91 ......

Unknown;

The 200th term of the sequence;

Solution:

Since we were given an arithmetic progression, we need to first find the common difference;

 Common difference  = second term - first term

                                     = 94 - 97  

                                     = -3

To find the 200th term, we use the expression below;

     Sn  = a + (n-1)d

   a is the first term

    n is the nth term

   d is the common difference

 S₂₀₀ = 97 + (200 - 1 ) x -3 = -500
