The shape of my field is an oval

It's oval rather than round because I have two eyes, and each has a separate field like the one pictured here. Putting them together creates an oval. So if you wanted to represent what I can see, you would take a wide-angle photo from my vantage point and cut out a roughly oval shape

Therefore, the shape of my field is an oval

What is the value of z?

VashaNatasha [74]

Answer:

z = 61

Step-by-step explanation:

The exterior angle is congruent (equal to) the sum of the 2 farthest angles from it, so you can set the equation like this:

z + z - 11 = z + 50

Add like terms, which would be the 2 "z's" on the left side:

2z - 11 = z + 50

Then subtract the z on the right side from both sides:

2z - 11 = z + 50

-z -z

___________

z - 11 = 50

Add 11 to both sides:

z - 11 = 50

+ 11 +11

________

z = 61

Noah has just purchased a previously owned home. he put $5,000 towards a down payment and took out a $65,000 mortgage. noah know

cricket20 [7]

The answer to your question is B) $700 because 1% of the $5,000 down payment and the $65,000 mortgage so $70,000 is $700.

a language arts test is worth 100 points there is a total of 26 questions . there are spelling word questions that ae worth 2 po

natka813 [3]

10 question of spelling words and 16 questions of vocabulary are present

Solution:

Let "x" be the number of spelling word questions

Let "y" be the number of vocabulary word question

There is a total of 26 questions. Therefore, we get

number of spelling word questions + number of vocabulary word question = 26

x + y = 26 --------- eqn 1

There are spelling word questions that worth 2 points each and vocabulary word question worth 5 points each

The language arts test is worth 100 points

Therefore, we frame a equation as:

number of spelling word questions x 2 + number of vocabulary word question x 5 = 100

$x \times 2 + y \times 5 = 100$

2x + 5y = 100 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 26 - y ------- eqn 3

Substitute eqn 3 in eqn 2

2(26 - y) + 5y = 100

52 - 2y + 5y = 100

3y = 100 - 52

3y = 48

Substitute y = 16 in eqn 3

x = 26 - 16

Thus 10 question of spelling words and 16 questions of vocabulary are present

Given the following geometric sequence, find the 12th term: {2, -4, 8, ...}.

BaLLatris [955]

2 times what = -4?
-2 does
-2 x 2 = -4

-4 time what = 8?
Again, -2.
-2 x -4 = 8

You could do this over and over again or make a table, or you can make a function.
f(n) = f(1) • r $^{n-1}$
f(1) in this case is 2.
f(n) = 2 • r $^{n-1}$
r is rate of change, which is -2.
f(n) = 2 • -2 $^{n-1}$
To find the 12th number in the sequence, just substitute n for 12.
f(12) = 2 • -2 $^{12-1}$
f(12) = 2 • -2 $^{11}$
-2^11 = -2048
2 x -2048 = -4096
So the 12th number in the sequence will be -4096.
