Answer:
1 foot
Step-by-step explanation:
Set equal:
4w² + 70w = 74
Move to one side:
4w² + 70w − 74 = 0
Simplify:
2w² + 35w − 37 = 0
Factor. Using the AC method, ac = 2×-37 = -74. Factors of -74 that add up to 35 are 37 and -2. Dividing by a, the factors reduce to 37/2 and -1/1.
(w − 1) (2w + 37) = 0
Set each factor to 0 and solve:
w − 1 = 0
w = 1
2w + 37 = 0
w = -18.5
Since w must be positive, w = 1. The width of the wood border is 1 foot.
The answer is is 4.2 because the 2 rounds up to 3 and the 3 does not round up the four so four does not round up the 2 so it is 4.2
$150.00 because if you add all of them up you’ll get 150
Answer:
The exact amount of people is 5,173 and the estimate amount is 5,000
Step-by-step explanation:
How I got 5,173 is simple. You take the amount of people that chose each location, and add both of those totals together. You would then get 5,173 if you wanted the exact answer. If you wanted to get the estimate amount here’s what you do. The first step is to take the first place, which is the beach, or you can choose the other place, the amusement park. Next is you estimate the amount of the total number. To estimate 2,862 (beach) or 2,311 (amusement park) you look at the first number which is 2 in this scenario. you then look at the next number which is either 8 (beach) or 3 (amusement park) then you tell yourself “is it greater then 5 or exactly 5?” if the number solves that answer then increase the first number which is 2. You then increase the 2 to 3. Now you do this for the next number. And the final step is after you estimate both numbers you add the estimates together. After you get the total (to know whether you did it correctly the answer has to end in 0’s) that is your estimate answer. (SORRY THIS WAS REALLY LONG, I JUST HAD ALOT OF INFORMATION TO GIVE. lol)
