The area of the farm is the number of trees on it.

Each row of the farm does not have 50 trees

Let

<em />x \to<em> number of rows</em>

<em />y \to<em> number of trees in each row</em>

<em />

So, we have:

<em />y = 2x - 10<em> --- twice less than the number of rows</em>

The area of the farm is:

Area = x \times y

Where

Area = 600 --- the number of trees

So, we have:

x \times y = 600

Substitute y = 2x - 10

x \times (2x - 10) = 600

Substitute 50 for x

50 \times (2 \times 50 - 10) = 600

50 \times (100 - 10) = 600

50 \times 90 = 600

4500 = 600

The above equation is not true.

This means that, each row does not have 50 trees

Find the value of z.
AVprozaik [17]

Answer:

  z = 110°

Step-by-step explanation:

Angles z and the one marked 70° form an linear pair, hence are supplementary.

  z = 180° -70° = 110°

<h3>Angles where chords cross</h3>

The angle made by two chords is half the sum of the arcs intercepted by those chords. Here, that means ...

  70° = 1/2(60° +x)   ⇒   x = 140° -60° = 80°

The arc w completes the circle of 360°, so we have ...

  w +x +79° +60° = 360°   ⇒   w = 360° -219° = 141°

Finally, z is the average of w and 79°:

  z = (w +79°)/2 = (141° +79°)/2 = 110° . . . as above

((I RAISED THE POINTS AND THIS IS MULTIPLE CHOICE))
NeTakaya

Answer:

B and D

Step-by-step explanation:

Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.

an = ar^(n-1)

d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .

1/3 * 2 = 2/3

2/3 * 2 = 4/3

4/3 * 2 = 8/3

where r = 2, constant multiplier is 2.  //Answer

b)  320, 80, 20, 5, 1.25, . . . . .

320 * 1/4 = 80

80 * 1/4 = 20

20 * 1/4 = 5

r = 1/4 //Answer

Answer: B and D

//Hope this helps.

X+ y =5<br> 3x-y=7<br><br> solve each system of equations by the addition method
erastovalidia [21]
X=3
Y=2
Use the "Guess and Check Method"
For example, I inputed 2 for X and found that it was too small to work for the second equation, so I put in 3. Then for Y, I input 2 because 3+2=5. I put 2 in to replace Y in the second equation (3x-y=7) to see that 9-2=7. Therefore, X=3 and Y=2
