Answer:

sum of angles = 40 + (8x + 4) + (3x + 4) = 180

Collecting all similar terms, the equation above becomes

11x + 8 = 140 ---> x = 12

Therefore. angle S = 3x + 4 = 3(12) + 4 = 40

A farmer wants to net at least $10,000/acre on the sale of his 80-acre property. If he allows for a total of 10% for commissions
lara [203]

Answer:

$11,111.11

Step-by-step explanation:

Net Money farmer wanted to get the on selling 1 acre = $10,000

Percentage of commission and closing cost incurred by him = 10%

out of 100 %, he will incur cost of 10%,

rest of them will be with him.

In percentage money he would have be = (100 - 10)% = 90%

Thus, 90 % will be net money he would have.

Let the list price be $x

Given that 90% of this $x will be with farmer which is equal to

90% of x = 90/100 * x = 0.9 x

It is given that he wants to net $10000

so 0.9x = $10,000

=> x =  $10,000/0.9 = $11,111.11.

Listing price per acre should be at least  $11,111.11.

3. A car starts from rest and accelerates uniformly over a time of 6.21 seconds
Klio2033 [76]

We have,

t = 6.21 s

s = 111 m

u = 0 m/s

To determine: "a" of the particle.

We know,

s = ut + ½ at²

⇒ s = ½ at²

⇒ a = 2s/t²

⇒ a = [2(111 m)]/(6.21 s)²

⇒ a = (222 m)/(38.5641 s²)

⇒ a ≈ 5.75 m/s²
