Step-by-step explanation:
1st question: Since they get 50 miles per hour because 4-1 equals 3. 350-200 equals 150. 150/3 = 50 miles per hour

The sum of three consecutive terms of an arithmetic sequence is 27, and the sum of their squares is 293. What is the absolute difference between the greatest and the least of these three numbers in the arithmetic sequence?
We want to find the absolute difference between the greatest and the least of 3 consecutive terms of an arithmetic sequence that meet some given criteria. We will get that the difference is 3.88 or 12.88.
We know that the difference between any pair of two consecutive terms in an arithmetic sequence is a constant.
So if that difference is D, we can write 3 consecutive terms as:
A, A + D, A + 2*D
The sum must be equal to 27, then we have:
A + (A + D) + (A + 2*D) = 27
And the sum of their squares is equal to 293, then we have:
A^2 + (A + D)^2 + (A + 2*D)^2 = 293
If we simplify these two equations we get:
3*A + 2*D = 27
3*A^2 + 6*D*A + 5*D^2 = 293
To solve this, we just need to isolate one of the variables in the first equation and then replace that in the other one.
3*A = 27 - 2*D
A = (27 - 2*D)/3 = 9 - (2/3)*D
Replacing that on the other equation we get:
3*(9 - (2/3)*D)^2 + 6*(9 - (2/3)*D)*D + 5*D^2 = 293
Now we can solve this for D:
3*(81 - 2*9*(2/3)*D + D^2) + 54*D - 4*D^2 + 5*D^2 = 293
(243 - 293) + 18*D + 4*D^2 = 0
-50 + 18*D + 4*D^2 = 0
That is just a quadratic equation, the solutions are given by:
[tex]D = \frac{-18 \pm \sqrt{18^2 - 4*4*(-50)} }{2*4} \\\\D = \frac{-18 \pm 33.53}{8}[/tex]
Then we have two possible values for D, we take the positive one to get:
D = (-18 + 33.53)/8 = 1.94
And the difference between the greatest and least of these 3 numbers is twice the common difference, so is equal to 2*D = 2*1.94 = 3.88
If instead we take the other solution, we get:
D = (-18 - 33.53)/8 = -6.44
Then the absolute difference is -2*D = -2*-6.44 = 12.88

Step-by-step explanation:
-1/2m=-18
m=36
answer is D
Answer:
m = 36
Step-by-step explanation:
[tex]\frac{1}{3} m+3-\frac{5}{6}m=-15[/tex]
Combine like terms:
[tex](\frac{1}{3} m+(-\frac{5}{6}m)[/tex]
[tex](\frac{2}{6} m+(-\frac{5}{6}m)[/tex]
[tex]-\frac{3}{6}m = -\frac{1}{2} m[/tex]

Subtract 3 from each side:

a cars gas tank holds 15 gallons of gas. the car used up 9 gallons of gas. what percent of the gas in the tank is remaining?
9514 1404 393
Answer:
40%
Step-by-step explanation:
15 -9 = 6 gallons remain. The fraction remaining can be expressed as a percentage by multiplying it by 100%.
fraction remaining = (remaining gallons)/(capacity) = 6/15 = 2/5
percent remaining = 2/5 × 100% = 40%

1. Joseph bought 23 pineapples and 37 green mangoes. If he combined all the fruits and shared these equally to his 3 brothers, how many fruits did each of them get?
2. There were 130 persons invited in a festival. The venue has rectangular tables that can sit 6 persons each. The longer side can sit two persons while the shorter side can sit one. The host arranges 6 tables in a row placed shorter end to shorter end. How many rows of tables are needed to sit all the invited guests?
1. Each if them would get 20 fruits
[tex]23 + 37 = 60[/tex]
[tex]60 \div 3 = 20[/tex]
2. There should be 5 rows of tables needed to sit all the invited guests
On every row there would be 26 people, so then we need to divide 130 by 26 and we get 5. Then if we check, 26 times 5 equals 130.
