Mathematics
1 answer:
Alisiya [41]3 years ago
7 0

Answer:

It will take 1 5/7 hours

Step-by-step explanation:

3/4 of an hour is;

3/4 * 60 minutes = 45 minutes

3 1/2 acres is done in 45 minutes

8 acres will be done in x minutes

Thus, mathematically;

3 1/2 * x = 8 * 45

7x/2 = 360

7x = 2 * 360

7x = 720

x = 720/7 minutes

Let us convert this to hours

That will be;

720/7/60 = 720/(60 * 7) = 720/420 = 12/7

= 1 5/7 hours

Which graph represents the solution set of the compound inequality -4≤3x-1 and 2x+4≤18?
Mkey [24]

we have

-4\leq 3x-1 ----> inequality A

-4\leq 3x-1 \\-4+1 \leq 3x\\-3 \leq 3x\\-1\leq x\\ x\geq-1

The solution of the inequality A is the interval ------> [-1,∞)

2x+4\leq 18 -------> inequality B

2x \leq 18-4

x \leq 14/2

x \leq 7

The solution of the inequality B is the interval ------> (-∞,7]

The solution of the compound inequality is

[-1,∞) ∩ (-∞,7]=[-1,7]

therefore

the answer in the attached figure
