Find the solution for the following: Three backpackers cooked rice for dinner. The first one gave 400g of rice and the second 200g of rice. The third one did not have any rice so he gave $6 to the other two. How should they divide the $6 in a fair way ( assume they equally shared the dinner) ?
Answer:
First backpacker should receive $4 and the second one $2
Step-by-step explanation:
notice that the total amount of rice for the three is 600 g.
Then, the first one that gave 400 g contributed 400 out of 600, that is 400/600 = 2/3
The second one contributed 200 out of 600, that is 200/600 = 1/3
then the first one should receive 2/3 of the $6 = (2/3) x 6 = $4
and the second one should receive 1/3 of the %6 = (1/3) x 6 = $2

I need help ASAP!! 1+(x-4)=-(3x+6)+1
Answer: x= -2
Step-by-step explanation: 1.) use PEMDAS
2.) distribute the 1 and -1 to (x+4) and (3x+6) --> 1+x+4 = -3x-6+1
3.) Put common terms on the same side (so x's together and the numbers together) so you will add 3 to the right side and add 3x to the left side
4.) that will get you 4x = -8 so then you will divide 4 to both sides to get x by itself
5.) Answer: x=-2

Would like an answer for this question. Which represents 7(45) using the distributive property to simplify? SELECT THE TWO THAT APPLY. 1# 7 (40 - 5) 2# 7 (4) + 7 (5) 3# 7 (40 +5) 4# 7 (40) + 7(5)
Answer:
7(45)=7(40)+7(5)
Step-by-step explanation:
We need to represent 7(45) using the distributive property to simplify.
We can write 45 as 40+5
So it becomes,
7(45) = 7(40+5)
Distributive property is : a(b+c)=ab+ac
a=7, b = 40 and c = 5
7(40+5)=7(40)+7(5)
So, the correct option is (4).
Your car can drive 300 miles on a tank of 15 gallons. How far can it drive on 40

The car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
Your car can drive 300 miles on a tank of 15 gallons
300 miles → 15 gallons
Let x be the number of miles or distance a car travel in 40 gallons
x → 40 gallons
300/x = 15/40
x = (300×40)/15
x = 800 miles
Thus, the car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.

Step-by-step explanation:
-8=-16+n
-8(+16)=-16(+16)+n get "n" by itself by adding 16 to both sides.
negative eight plus sixteen is positive eight. on the right side the sixteens cancel eachother out, so you are left with just "n".

Under which conditions does the commutative property apply to compositions of f(x) and g(x)? A- When they are inverse functions B- when they are equal for at least one value of x C- when they are equal for all values of x D- when they are not inverse functions
Answer:
A- When they are inverse functions
C- when they are equal for all values of x
Step-by-step explanation:
The order of function application in a composition can be reversed if ...
the functions are inverses of each otherthe functions are identical (equal for all values of x)_____
In the first case, the composition gives an output equal to its input for the functions in either order.
In the second case, you cannot tell the functions apart, since they produce the same output for the same input. Hence, you can't tell if they are reordered or not.

Find the midpoint of the segment joining X(5,6) and Y(9,2).
Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is:
[tex]M=(\frac{x_1+x_1}{2},\frac{y_1+y_2}{2})[/tex]
Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:
[tex]M=(\frac{5+9}{2},\frac{6+2}{2})[/tex]
Add:
[tex]M=(\frac{14}{2},\frac{8}{2})[/tex]
Divide by 2:
[tex]M=(7,4)[/tex]
So, our midpoint is (7,4).
And we're done!
11(15g-13)=-6 help please
Answer:
g = 0.83
Step-by-step explanation:
11(15g-13) =-6
165g - 143 = -6
165g = 137
165 165
g = 0.83
The solution of the given equation 11(15g-13) = -6 is g = 0.83
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
11(15g-13) = -6
To solve the above equation following steps are taken,
Divide both the side of the equation by 11
11(15g-13)/11 = -6/11
Solving them we get,
15g - 13 = -6/11
Adding 13 both the sides,
15g - 13 + 13 = -6/11 + 13
So we obtain,
15g = -6/11 + 13
Solving the numbers right hand side,we get
15g = 137/11
Dividing both the sides by 15 we get,
g = 137/165
or, g = 0.83
Hence,The solution of the given equation 11(15g-13) = -6 is g = 0.83

How do you find the area?
Answer:
• First attachment's graph is correct
• Second attachment, the area is approximately 8.6
Step-by-step explanation:
Remember that the area between two curves is defined as the following:
[tex]\mathrm{The\:area\:between\:curves\:is\:the\:area\:between\:curve\:f(x)\:and\:curve\:g(x)\:on\:interval\:[a,b]} :\\A=\int _a^b|f\left(x\right)-g\left(x\right)|dx[/tex]
We are given the curves y = 7cos(2x), and y = 7 - 7cos(2x) on interval [0, π/2]. Therefore, applying the area formula, we have the solve the following integral:
[tex]\int _0^{\frac{\pi }{2}}\left|7\cos \left(2x\right)-\left(7-7\cos \left(2x\right)\right)\right|dx[/tex]
From now on take a look at the attachment. It shows how to solve the integral, and it's exact value. The area is not 9.727 as you entered, it is approximately 8.6. Your graph however was accurate, but there can be no work shown for that as it's much easier to use a graphing calculator.
How do you do this question?
Answer:
240 ft
Step-by-step explanation:
When she stops, her velocity is 0. The first time that happens is at t = 3 minutes. Her position at that time is equal to the area under the curve.
You can use area of a trapezoid, or you can split the shape into two triangles and a rectangle. Watch your units! Speed is given in ft/s, and time is given in minutes.
Using trapezoid area:
A = ½ (1 min + 3 min) (2 ft/s)
A = ½ (60 s + 180 s) (2 ft/s)
A = 240 ft
