hope this helps and make me brainliest
Step-by-step explanation:
. You have that:
- The homeowner want the length of the swimming pool to be 4 feet longer than its width.
- He wants to surround it with a concrete walkway 3 feet wide.
- He can only afford 300 square feet of concrete for the walkway.
2. Therefore, the tota area is:
At=L2xW2
L2 is the lenght of the walkway (L2=L1+3+3⇒L2=(W1+4+6)⇒L2=W1+10).
W2 is the width of the walkway (W1+3+3⇒W2=W1+6)
3. The area of the walkway is:
A2=At-A1
A2=300 ft²
4. Therefore, you have that the width of the swimming pool is:
A2=(W1+10)(W1+6)-(W1+4)(W1)
300=(W1²+6W1+10W1+60)-(W1²+4W1)
W1²+16W1+60-W1²-4W1-300=0
12W1-240=0
W1=240/12
W1=20 ft
5. And the length is:
L1=W1+4
L1=20+4
L1=24 ft
Answer:
Either increase the number of acres that can be used for strawberry fields (by buying more land)..If we use the same numbers from earlier, then the farmer should use approximately 16.65 acres of land (or just 17 acres of land)
So if the farmer has 17 acres of land or more, then he will make more than $70,000 per year
Step-by-step explanation:
Use the proportions from earlier
We have the point (5, 21000)
70,000/21,000 = 3.3
To find the x-value multiply 3.3 by 5
3.3 * 5 = 16.65
We can even use the other point's values to find the exact same answer
Point (3.5, 14700)
70,000/14,700= 4.7619047619
4.7619047619 * 3.5 = 16.66 (literally about the same)
