What is Bio-Fuel?Bio-fuel is a type of fuel that is created quickly from biomass, as opposed to the lengthy natural processes that result in the development of fossil fuels like oil. Plants may be used to make biofuel, as well as home, commercial, and agricultural biowaste.
Given data ,
Any fuel that is made from biomass, or plant, algae, or animal waste, is referred to as a biofuel. Unlike to fossil fuels like petroleum, coal, and natural gas, biofuel is seen as a source of renewable energy due to the ease with which such feedstock material may be supplied.
In light of rising petroleum prices and growing concern about the role fossil fuels play in global warming, biofuel is frequently promoted as a convenient and ecologically friendly substitute for petroleum and other fossil fuels.
Hence , the alternative to power a car is bio-fuel

The volume of a pyramid that fits exactly inside a cube is 10 cubic feet. What is the volume of the cube? (5 points)
30 cubic feet
100 cubic feet
300 cubic feet
1000 cubic feet
Answer:
30 cubic feet
Step-by-step explanation:
volume of a pyramid is (l*w*h)=3
assuming it is a pyrmaid where l=w=h, volume = x^3/3 = 10
x^3=30
x=30^(1/3)
volume of a cube is l*w*h, with our assumption, that translates to x*x*x
Volume = 30^(1/3)*3 = 30 cubic feet
The volume of the cube, in relation to the given pyramid is: 30 cubic feet.
What is a Cube?Volume of a pyramid = 1/3(l × w × h)Volume of a cube = l × w × hRelating both volumes, we would have:
Volume of cube = 3(volume of pyramid)
Volume of pyramid is given as 10 cubic feet, therefore:
Volume of the cube = 3(10)
Volume of the cube = 30 cubic feet.

Help Pls. Find the radius of Circle Q.
The radius of the given circle is 13 unit.
What is a chord of a circle?
The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.
What is radius of a circle?A radius is a measure of distance from the center of any circular object to its outermost edge or boundary.
What is Pythagoras theorem?Pythagoras theorem states that "the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides".
According to the given question
We have a circle with center Q and two chords AD and BC.
And, AD = 4x + 4 and BC = 6x -6
Since, both the chords are at the same distance from the center of the circle, so their lengths will same.
⇒ AD = BC
⇒ 4x + 4 = 6x -6
⇒ 4 + 6 = 6x -4x
⇒ 10 = 2x
⇒ x = 5
Therefore,
AD = 4x + 4 = 4(5) + 4 = 20 +4 =24
and, BC = 6x - 6 = 6(5) - 6 = 30 -6 = 24
Also, AP = AD/2 = 24/2 = 12
Now, in right angle triangle QPA we have
[tex]AQ^{2} =QP^{2} +AP^{2}[/tex] ( By Pythagoras theorem)
⇒ [tex]AQ^{2} = 5^{2} +12^{2}[/tex]
⇒[tex]AQ^{2} = 25 + 144[/tex]
⇒[tex]AQ^{2} = 169[/tex]
⇒[tex]AQ =\sqrt{169}[/tex]
⇒ AQ = 13

Mr. Alhammadi is shopping for school supplies with his children. Rashed selected 3 one-inch binders and 2 two-inch binders, which cost a total of 29 dirhams. Matar selected 5 one-inch binders and 2 two-inch binders, which cost a total of 35 dirhams.
Write a system of equations that represents the above situation.
I need help ASAP please :(
Answer:
3x + 2y = 29
5x + 2y = 35
Step-by-step explanation:
Let
x = cost of one-inch binders
y = cost of two-inch binders
Rasheed:
3x + 2y = 29 (1)
Matar:
5x + 2y = 35 (2)
3x + 2y = 29 (1)
5x + 2y = 35 (2)
Using elimination method, subtract (1) from (2)
5x - 3x = 35 - 29
2x = 6
x = 6/2
x = 3
Substitute x = 3 into (1)
3x + 2y = 29 (1)
3(3) + 2y = 29
9 + 2y = 29
2y = 29 - 9
2y = 20
y = 20/2
y = 10

If you were to pick one day of the year at random, is it more likely that the day would be a Tuesday or that the day would fall during the month of January?
Answer and explain in your own words why you chose what you chose.
Answer: It's more likely it's a Tuesday
========================================================
Explanation:
The odds of it being a Tuesday is 1/7 since there's 1 day of the week that's Tuesday out of 7 total.
The odds of it being January is 1/12 because we have 1 month we want out of 12 total.
Now the question is: which fraction is larger?
For now, assume they are equal. We'll cross multiply like so
1/7 = 1/12
1*12 = 7*1
12 = 7
We get a false statement at the end, but we can fix things by replacing the equal sign with a greater than sign to get this new set of steps
1/7 > 1/12
1*12 > 7*1
12 > 7
which leads us to a true statement. Therefore, 1/7 is the larger fraction and the more likely event.
-----------------
Alternatively, you can use your calculator to find that:
1/7 = 0.143 approximately1/12 = 0.083 approximatelyThen for each decimal, move the decimal point 3 spots to the right. The values 0.143 and 0.083 become 143 and 83 respectively. We can see that 143 is larger, which means 0.143 is larger, and lastly 1/7 is larger. Think of it like a chain.
4-2(x+7)=3(x+5) solve the equation
Answer:
-5
Step-by-step explanation:
Our first step is to distribute/expand in the brackets so we are able to isolate x-term.
[tex] \large{4 - 2x - 14 = 3x + 15}[/tex]
I hope you still remember that when multiplying positive with negative, it becomes negative. Then we combine like terms - we isolate the 2x by adding 2x both sides and subtract both sides by 15.
[tex] \large{4 - 2x - 14 + 2x - 15 = 3x + 15 + 2x - 15} \\ \large{ - 25 = 5x}[/tex]
Then to divide both sides by 5 so we can finally get the x-term isolated.
[tex] \large{ \frac{ - 25}{5} = \frac{5x}{5} \longrightarrow - 5 = x}[/tex]
Dividing the negative by positive results in negative as well! Next step is optional, which is about checking the answer. To check the answer if it's right or not, we can do by substituting x = -5 in the equation and solve until these two outcomes may occur:
Both sides are different (Ex. 2 = 5). This means that the answer is not correct or not a part of the equation.Both sides are equal/same (Ex. 4 = 4). This means that the answer is correct and a part of the equation.[tex] \large{4 - 2(x + 7) = 3(x + 5)}[/tex]
From the given equation above, substitute the value of x which is -5 in the equation.
[tex] \large{4 - 2( - 5 + 7) = 3( - 5 + 5)}[/tex]
Evalute/Simplify:
[tex] \large{4 - 2(2) = 3(0) \longrightarrow 4 - 4 = 0} \\ \large \boxed{0 = 0}[/tex]
Since both sides are equal or same. Thus the solution to this equation is x = -5.
Answer
x = -5I hope this helps! If you have any doubts or questions, don't hestitate to ask in the comment! Good luck on your assignment and have a great day! :)

The number of Roberto’s baseball cards is ¾ the number of David’s cards If Roberto gives ½ of his cards to David, what will be the ratio of Roberto’s cards to David’s cards? please help me. I need it to step by step equations!!!!
Answer:
1/4, 0.25
Step-by-step explanation:
Answer:
3/11
Step-by-step explanation:
Let Roberto's cards be x.
Let David's cards be y
x = (3/4) y
Roberto gives half his cards away which is 1/2*(3/4) = 3/8
David's new amount after the gift = 1/2(3/4)y + y = 3/8y+y=3y/8+8y/8 = 11y/8
So the ratio is Roberto / David = (3/8) // (11/8)
Roberto to David = 3/8 // 11.8 which you now invert and multiply the denominator
Roberto to David = 3/8 * 8/11 = 3/11
