how many litters of oil are in the rank
round the answer to the nearest liter
Answer:
3927 litres
Step-by-step explanation:
V=hpir²

Solve the following equation algebraically: x squared = 12
Answer:
x=3.46
Step-by-step explanation:
Answer:
-3.4641 and 3.4641 or x= -2√3 and x= 2√3
Step-by-step explanation:
x²=12 take the square root of both sides
x=±2√3 separate the solutions
x= -2√3 or x= 2√3 solve

WHOEVER EXPLAINS ALL THEIR WORK AND GOES THROW EAXH STEP WILL GET BRAINLEST THAT IS COMPLETELY FINISEHD. write the equation of the line that goes through the points (3,2) (4,-1) show ALL steps and EXPLAIN what you are doing in each step. you will be graded on showing all the steps and your explanation.
Answer:
[tex]y = -3x+11[/tex]
Step-by-step explanation:
I accept your challenge!
First we know that a equation of the line is a linear equation, and its equation is:
[tex]y = mx+b[/tex]
[tex]m: \text{slope}\\b: \text{y-intercept}[/tex]
In this context, the slope, defined as the steepness of a line is characterized as the ratio of RISE (the difference in the y-coordinates, the vertical change) over the RUN (the difference in x-coordinates, the horizontal change).
[tex]$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} $[/tex]
Once we know two points where the line goes through, we can get the slope, once we know the change in y and x.
I will take [tex](3,2)[/tex] as Point 1 and [tex](4,-1)[/tex] as Point 2.
So, [tex]x_{1}=3 \text{ and } y_{1}=2\\x_{2}=4 \text{ and } y_{2}=-1[/tex]
[tex]$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{-1-2}{4-3} $[/tex]
[tex]$m=\frac{-3}{1}=-3 $[/tex]
Now we have to find the y-intercept:
To do so, think about the the points given and the nearly finished equation, we can find b with those two informations.
Our currently equation of the line is:
[tex]y = -3x+b[/tex]
Using the points, take Point 1 as an example, it says that when [tex]x = 3, y = 2[/tex], so plugging it in the equation:
[tex]2 = -3(3)+b\\2 = -9+b\\11 = b[/tex]
Taking the Point 2
[tex]-1 = -3(4)+b\\-1 = -12+b\\11 = b[/tex]
Now we found [tex]b[/tex]! The equation is complete!
[tex]y = -3x+11[/tex]
A bird sanctuary needs at least 500 lbs of corn per month. The storage shed
contains 87 lbs of corn on the first day of the month. If corn is bought in 40-lb
bags, which inequality can be used to calculate how many bags of corn, x, are
needed for the month?
Answer:
x≥(500-87)/40
Step-by-step explanation:
You need 500 lbs and already have 87 so you need at least 413 bags. You divide you 40 because they come in 40 pound bags. Round up so that you have the minimum number of bags necessary to reach 500 lbs of corn.

Answer:
Length of DE = 22.8cm
Step-by-step explanation:
Given: 23° and 8.9cm
To find the length of DE, we need to use the SOH-CAH-TOA method.
Since DE is the hypotenuse (The longest side), we need to use SOH meaning sinФ([tex]\frac{opposite}{hypotenuse}[/tex]).
The opposite of the angle, 23° is 8.9cm, by replacing the formula with the given, we would get the following: sin(23°)=([tex]\frac{8.9}{x}[/tex]).
To calculate, we need to multiply 'x' to both sides: x*sin(23°) = 8.9
Using a calculator, sin(23°) is 0.39
0.39x = 8.9
By dividing 0.39 to both sides, we should end up with 22.8cm (rounded to the nearest tenth of a centimeter).

Step-by-step explanation:

The protein in the bag of dog food is 8 pounds.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Weight of the bag = 35 pounds
Percentage of the weight of protein = 23%
The weight of the protein in the bag.
= 23% of 35 pounds
= 23/100 x 35
= 8.05 pounds
= 8 pounds
Thus,
The weight of the protein is 8 pounds.

Which of the following equations is an example of a quadratic equation? y = |6 x| y = 9 y = x - 5 y = x 2 - 5
The scale on a map shows that 5 centimeters = 2 kilometers. What number of centimeters on the map represents an actual distance of 5 kilometers?
A. 50 cm
B. 12.5 cm
C. 10.5 cm
D. 2 cm
Given that 5 centimeters equals 2 kilometers, we are asked to find how many centimeters equals to 5 kilometers.
So, we know the rate is 5 centimeters is equal to 2 kilometers.
We should find out how many centimeters equals 1 kilometer.
To do this, we can divide 5 centimeters by 2 to find out how many centimeters is 1 kilometer.
5/2 = 2.5
So, the new rate is 2.5cm = 1km.
Then, all we need to do is multiply the new rate by 5 to find out how many centimeters is 5 kilometers.
5 x 2.5 = 12.5
Therefore, 12.5 centimeters equals a distance of 5 kilometers.
Answer:
B.
Step-by-step explanation:
2 kilometer = 5 cm
And
5 km = ? cm
Using unitary method
2 km = 5 cm
1 km = 5/2 cm
1 km = 2.5 cm
Now
Multiplying both sides by 5 we'll get:
5 km = 2.5 × 5 cm
5 km = 12.5 cm

give your answer in the simplest form.
Answer:
Fraction of drink that is water = = 0.875 = 87.5 %
Explanation:
400 ml of squash is made by mixing 50 ml of cordial with water.
Total volume of squash = 400 ml
Total volume of cordial = 50 ml
Total volume of water = 400 - 50 = 350 ml
Fraction of drink that is water = Volume of water/ Volume of squash
= 350/400
= 7/8

two consecutive integers have a sum of 51 . find the integers
First represent your two consecutive integers as follows.
X ⇒ first integer
X + 1 ⇒ second integer
Since their sum is 51, our equation reads x + x + 1 = 51.
Now combine like terms to get 2x + 1 = 51.
Now subtract 1 to isolate the 2x and this gives us 2x = 50.
Since 2 is being multiplied by x, to get x by itself, we need
to divide by 2 on both sides of the equation to get x = 25.
If x = 25, then x + 1 would be 25 + 1 or 26.
So our two consecutive integers are 25 and 26.

Find three solutions for the linear equation 4x −3y = 1, and plot the solutions as points on a coordinate plane.
Answer:
(1, 1), (2, 2.333) and (3, 3.666).
Step-by-step explanation:
To find solutions for this equation, we can just choose values for x and then calculate the values of y.
So, for x = 1, we have:
4*1 - 3y = 1
3y = 3
y = 1
For x = 2, we have:
4*2 - 3y = 1
3y = 7
y = 2.333
For x = 3, we have:
4*3 - 3y = 1
3y = 11
y = 3.666
The points we need to plot is (1, 1), (2, 2.333) and (3, 3.666).
Check the image attached for the plot.
Three solutions for the linear equation are: (0, -0.333), (1,1) and (3, 3.667).
The graph is given at the end of this answer.
-----------------------------
The equation is:
[tex]4x - 3y = 1[/tex]
In slope-intercept formula, we have that:
[tex]3y = 4x - 1[/tex]
[tex]y = \frac{4}{3}x - \frac{1}{3}[/tex]
Thus, the solutions are given by the following pairs of points: [tex](x, \frac{4}{3}x - \frac{1}{3})[/tex]
-----------------------------
For x = 0, we have that [tex]y = \frac{4}{3}(0) - \frac{1}{3} = -\frac{1}{3} = -0.333[/tex], thus, one solution is (0, -0.333).
For x = 1, we have that [tex]y = \frac{4}{3}(1) - \frac{1}{3} = \frac{3}{3} = 1[/tex], thus, one solution is (1,1).
For x = 3, we have that [tex]y = \frac{4}{3}(3) - \frac{1}{3} = \frac{11}{3} = 3.667[/tex], thus, one solution is (3, 3.667).
These solutions are labeled on the graph given at the end of this answer.

K is the midpoint of JL
JK 2x + 4 and
KL = 4x - 8
Find JL.
Step-by-step explanation:
If K is the midpoint of JL, then JK and KL will be congruent to each other because a midpoint divides a line into two congruent segments.
JK ≅ KL
Now, let's add in the expressions.
2x + 4 = 4x - 8
-2x + 4 = -8
-2x = -12
x = 6
So, the value of x is equal to 6. Since JK is congruent to KL, then we can plug in x for one of the equations and multiply that answer by 2 so we can find the measurement of JL.
JK = 2(6) + 4
JK = 12 + 4
JK = 16
16 * 2 = 32
So, the measurement of JL is equal to 32.
