During the first quarter of the year, a company earned $1,400,000. The company estimates this to be about 20% of the total earnings for the year. What does the company estimate to be the total earnings for the year?
Which picture and equation best represent the problem?
If x is the total earnings in a year then 0.20x = 1400000 will be the equation and the second picture best represent the problem.
What is the percentage?The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
The percentage is also called the indicating hundredths.
Let's x is the total earnings in the year.
As per the given question,
20% of total earnings x is $1400000
Then, 20 % of x = 1400000
(20/100)x = 1400000
0.20x = 1400000
The 20% of 100% is the little (1/5)th portion of the circle which is shown in the second picture correctly.
Hence"If x is the total earnings in a year then 0.20x = 1400000 will be the equation and the second picture best represent the problem".

3. the 3 is the number of gallons, and the "d" is the cost per gallon.
the g is the number of gallons and the "3" is the cost per gallon.
Step-by-step explanation:
3g + d = (something).
g + 3d = (something).
Let's multiply every number by 2 as example.
6g + 2d = 2
2g = 6d = 2
(change it to x and y)
6x + 2y = 2
2x + 6y = 2

Hayden had 2 1/2 gallons of water in his watering can. The seed packet said to use 14 of a gallon for peppers and 5/8 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 3/4 gallons of water left over, about how much water did he use for lettuce?
A. 0 gallon
B. 1/2 gallon
C. 1 gallon
D. 1 1/2 gallon
Answer: So what I would do first is add 14 and 58 together, then subtract it from 212 to get 140.
Then subtract 34 gallons from 140 gallons, to get 106. So I think it’s 106, Sorry if I’m wrong...

Answer:
78.0 ft
Step-by-step explanation:
pythagoras theorem =
a² + b² = c²
a² + 36² = 85.9²
a² + 1296 = 7378.81
a² = 7378.81 - 1296
a² = 6082.81
a = √6082.81
a = 77.992....
