The answer is C. 100 because the total measure of a quadrilateral is 360. When you add up the 3 interior angle measures, it adds up to 260. Then you subtract 360-260 to get 100 as the fourth angle measure. Hope that this helped!

Parallel to y=2/3x+4 and goes through (-9,-2)
Ostrovityanka [42]
Hey there :)

y = \frac{2}{3}x + 4

Since this line is parallel to the line to be found, both have the same slope: \frac{2}{3}

Coordinates: ( - 9 , - 2 )

y - ( -2 ) = \frac{2}{3} ( x - ( -9 ) )
y + 2 = \frac{2}{3} x + 6
y = \frac{2}{3} x + 6 - 2

y = \frac{2}{3}x + 4

klemol [59]
Remark
I'm going to assume you are in the Northern Hemisphere. 

Answer
A looks like you are beginning in Winter. The temperature is down quite a bit. That would be about October where I live. B is spring because the temperature is rising but not at it's peak. That would be about April May here. 

C is summer. Glorious warm summer. June July and August.

D is autumn. The temperature is falling and it is just about at it's low peak again.

Find all pairs of prime numbers (a,b) such that a^b✖️b^a+1 is prime
Alenkasestr [34]

The pairs of prime numbers (a,b) between 1 and 10 inclusive such that a^b * b^a+1 is prime are

<h3>How to determine the pairs of numbers?</h3>

The expression that is a prime number is given as:

a^b * b^a + 1

The boundary or range of numbers of a and b is not given.

So, we make use of numbers between 1 and 10

i.e. 1 ≤ a ≤ 10 and 1 ≤ b ≤ 10

Using the above range, we have the following program to determine the pairs of prime numbers (a, b).

for a in range(1,11):

   for b in range(1,11):

       num = (a* *b) * (b* *a) + 1

       flg = False

       if num > 1:

           for i in ra nge(2, num):

               if (num % i) == 0:

                   flg = True

                   break

       if not flg:

           print(str(a)+","+str(b))

The output of the above program is:

(1,1), (1,2), (1,4), (1,6), (1,10), (2,1), (2,2), (2,3), (2,4), (3,2), (4,1), (4,2), (4,4) and (4,6)

The above represent all pairs of prime numbers (a,b) such that a^b * b^a+1 is prime
