Answer:
D
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]
[tex]-\frac{1}{2}m+3=-15[/tex]
Subtract 3 from each side:
[tex]-\frac{1}{2}m=-18[/tex]
Multiply each side by -2:
[tex]m = 36[/tex]

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.

Easy question:
Pump A can fill a tank of water in 6 hours. Pump B can fill the same tank in 10 hours. How long would it take the two pumps, working together, to fill the tank?
Answer:
3 hours and 45 minutes
Step-by-step explanation:
let's assume the tank has a volume of x liters.
let's assume the speed of filling it is x/6 liters per hour for A and x/10 liters per hour for B.
the formula to calculate the time is:
time = volume / speed
If the pumps work together, the total speed is x/6 + x/10, which is 16/60 x
So the time this takes is:
time = x / (16/60 x) = 60/16 hours = 3.75 hours = 3 hours and 45 minutes.

Step-by-step explanation:
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

A piece of wire 22 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral triangle. (a) How much wire should be used for the square in order to maximize the total area
9.56 m of the wire should be used for the square, to maximize the total area of the wire
Let x be the side length of the square.
So, the perimeter of the square is:
[tex]\mathbf{P_s=4x}[/tex]
Let y represent the side length of the equilateral triangle.
So, the perimeter of the triangle is:
[tex]\mathbf{P_t=3y}[/tex]
The length of the wire is given as:
[tex]\mathbf{P=22}[/tex]
This implies that:
[tex]\mathbf{P_s + P_t=22}[/tex]
Substitute values for Ps and Pt
[tex]\mathbf{4x + 3y=22}[/tex]
Make y the subject
[tex]\mathbf{y=\frac{22 -4x}3}[/tex]
For an equilateral triangle of side length y, the height (h) of the triangle is:
[tex]\mathbf{h =\frac y2\sqrt 3}[/tex]
The area of the triangle is then calculated as:
[tex]\mathbf{A_t = \frac 12 yh}[/tex]
This gives
[tex]\mathbf{A_t = \frac 12 y\times \frac y2\sqrt 3}[/tex]
[tex]\mathbf{A_t = \frac{y^2}{4}\sqrt 3}[/tex]
The area of the square is:
[tex]\mathbf{A_s = x^2}[/tex]
So, the total area is:
[tex]\mathbf{A = A_s + A_t}[/tex]
[tex]\mathbf{A = x^2 + \frac{y^2}{4}\sqrt 3}[/tex]
Substitute [tex]\mathbf{y=\frac{22 -4x}3}[/tex]
[tex]\mathbf{A = x^2 + (\frac{22 - 4x}{3})^2 \times \frac{\sqrt 3}{4}}[/tex]
Differentiate
[tex]\mathbf{A' = 2x + \frac{\sqrt 3}{4} \times \frac 19 \times 2(22 - 4x) \times (-4)}[/tex]
[tex]\mathbf{A' = 2x - \sqrt 3 \times \frac 19 \times 2(22 - 4x) }[/tex]
[tex]\mathbf{A' = 2x - \frac{2\sqrt 3}9 (22 - 4x) }[/tex]
Set to 0
[tex]\mathbf{2x - \frac{2\sqrt 3}9 (22 - 4x) = 0}[/tex]
Rewrite as:
[tex]\mathbf{2x = \frac{2\sqrt 3}9 (22 - 4x) }[/tex]
Divide through by 2
[tex]\mathbf{x = \frac{\sqrt 3}9 (22 - 4x) }[/tex]
Multiply through by 9
[tex]\mathbf{9x = \sqrt 3 (22 - 4x) }[/tex]
Open bracket
[tex]\mathbf{9x = 22\sqrt 3 - 4x\sqrt 3 }[/tex]
Collect like terms
[tex]\mathbf{9x +4x\sqrt 3= 22\sqrt 3 }[/tex]
Factor out x
[tex]\mathbf{x(9 +4\sqrt 3)= 22\sqrt 3 }[/tex]
Solve for x
[tex]\mathbf{x= \frac{22\sqrt 3}{9 +4\sqrt 3} }[/tex]
Simplify
[tex]\mathbf{x= \frac{38.11}{9 +6.93} }[/tex]
[tex]\mathbf{x= \frac{38.11}{15.93} }[/tex]
[tex]\mathbf{x= 2.39 }[/tex]
Recall that, the perimeter of the square is:
[tex]\mathbf{P_s=4x}[/tex]
So, we have:
[tex]\mathbf{P_s=4 \times 2.39}[/tex]
[tex]\mathbf{P_s=9.56}[/tex]
Hence, 9.56 m of the wire should be used for the square

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%

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
(x, y) → (x + 5, y – 3)
(x, y) → (x + 5, y + 3)
(x, y) → (x – 3, y + 5)
(x, y) → (x + 3, y + 5)
Answer: Choice C
(x, y) → (x – 3, y + 5)
=================================================
Explanation:
The "5 units up" portion means that each y value increases by 5. Therefore, we go from y to y+5. Going from x to x-3 means that we shift each point 3 units to the right.
For example, if the starting point is (1,7), then we have the following steps:
[tex](x,y) \to (x-3,y+5)\\\\(1,7) \to (1-3,7+5)\\\\(1,7) \to (-2,12)\\\\[/tex]
The point (1,7) moves 5 units up and 3 units to the left to arrive at (-2,12).
Note that the order doesn't matter. We could start moving 5 units up, then go 3 units left. Or we could start going 3 units left, then 5 units up. We'll arrive at the same destination.
