An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7. There are different types of equations like linear, quadratic, cubic, etc.
Let's consider Almonds be a and Peanuts be p.
from given conditions,
a + p = 20
and 5.95 a + 2.95 p = 4(20)
5.95 a + 2.95 p = 80
take, a = 20 - p
5.95 (20 - p) + 2.95 p = 80
119 - 5.95 p + 2.95 p =80
119 - 3 p = 80
3p = 39
p = 39/3
p = 13
Therefore, there are 13 pounds of peanuts present in the mixture.

The wind force f on a sail varies jointly as the area a of the sail and the square of the wind speed w. The force on a sail with an area of 500 ft^2 is 64. 8 pounds when the wind speed is 18 mph. What would be the force for a sail with an area of 250 ft^2 with a wind speed of 35 mph
Answer:
122.5 pounds.
Step-by-step explanation:
f = kaw^2
So, k = f/aw^2
From the given data:
k = 64.8/(500*18)
= 0.0004
When a = 250 and w = 35:
f = 0.0004*250*35^2
= 122.5

We need to figure out what y is for x equals:
2
0
4
So, lets plug in these number:
Lets start with 2:
y=2+8
=
y=10
So the first y value is 10.
Next we have:
y=0
y=0+8

(a+b+c)(a-b+c)=a2+b2+c2 prove
Answer:
There might be an error in the question, the result below should be the correct answer. It is not possible for a^2+b^2+c^2 to be the answer.
(a+b+c)(a-b+c) = a^2 +2ac - b^2 + c^2
Step-by-step explanation:
(a+b+c)(a-b+c) = a^2 - ab +ac + ba - b^2 +bc + ca - cb + c^2 (expanding the two terms in brackets first)
Since ab = ba, ac = ca and bc = cb,
-ab and ba can be cancelled out
bc and -cb can be cancelled out
Hence, (a+b+c)(a-b+c) = a^2 +2ac - b^2 + c^2
This is what I have obtained through expansion, then simplification by cancelling out the common terms.

A graph which represents the solutions to this equation x² + 8x = -20 include the following: B. Linear-quadratic system graph shows upward parabola with vertex at (minus 4, 4) and passing through (minus 2, 8), and (minus 6, 8).
What are quadratic functions?In Mathematics, the graph of every quadratic functions (equations) is either an upward or downward parabola, which is typically a u-shaped curve. This ultimately implies that, the graph of a quadratic function (equation) would always form a parabolic curve.
Next, we would re-write the given quadratic function in standard form by equating it to zero (0) as follows;
x² + 8x = -20
Adding 20 to both sides of the linear-quadratic equation, we have the following:
x² + 8x + 20 = -20 + 20
x² + 8x + 20 = 0
In this scenario, we would use an online graphing calculator to plot the graph of the given quadratic function and then determine the point of intersection and vertex.
y = x² + 8x + 20
By critically observing the graph of the given quadratic function, we can logically deduce that the solutions and vertex are as follows;
x = -6, y = 8.
x = -2, y = 8.
Vertex = (-4, 4).

The 19th and 15th term of an AP are -5 and -7 1/2 repectively. What i the um of the firt 20 term
The sum of first 20 terms of the AP will be -206.25
As in AP, let us assume that the "a" be the first term and 'd' be the common difference.
So, the value of nth term can be determined by using formula: a_n=a+(n-1)d, where, n = number of terms, and d = common difference.
So, the value of 19th terms = a+(19-1)d = a+18d = -5 -----(i)
And the value of 15th term = a+(15-1)d = a+14d = -7(1/2) ----(ii)
Now subtracting (ii) from (i),
We will get,
4d = 2(1/2)
=>4d = 2.5
=>d = (2.5/4) = 0.625
Now putting value of "d" in (i)
We will get,
a+(18*0.625) = -5
a=-5-11.25 = -16.25
We have, the formula for finding the sum of terms:
Sum of terms can be determined by using formula:
Sum = (n/2) × [2a + (n-1)d]
Here, n = 20, a = -16.25, d = 0.625
We will get sum of first 20 terms as:
[tex](n/2)\times [2a + (n-1)d]\\(20/2) \times [2 \times -16.25+(20-1)0.625]\\[/tex]

The state transportation commission counted cars traveling east and west across a toll bridge. The commission counted 486 cars traveling east and 189 cars traveling west. What percentage of the cars were traveling east?
The percentage of cars traveling east is 28% of the total number of cars.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The commission counted 486 cars traveling east and 189 cars traveling west.
We know percentage change we'll divide the net amount change by the original amount and multiply it by 100%.
From this concept, the percentage of the cars were traveling east would be
The cars traveling east divided by the total numbers of cars time s100%.
= (189/486 + 189)×100%.

Answer: length of EF is 18 units.
Step-by-step explanation:
similar triangles (as displayed in the photo) have the same angle measures, but can have different side lengths. however, these side lengths are proportional to each other, meaning that with similar triangles, there will ALWAYS be a number you can multiply the first triangle by to get its similar triangle.
you can find this number by dividing one side length of whichever triangle is bigger with its corresponding side on the other triangle (for example, sides DF and AC correspond, so you'd divide whichever value's bigger by the smaller one. in this case you'd divide 21 by 14.) this gives you 1.5, which tells you that triangle DEF is 1.5 times larger than triangle ABC. so to get EF, just multiply BC (which is 12) by 1.5. this gives you 18. so, EF equals 18. hope this helped :3

On the return journey, due to a strong head wind, the plane travelled 1200 km in the same time it took to complete the outward journey. On the outward journey, the plane was able to maintain an average speed 20 km/hr greater than on the return journey. Calculate the average speed of the plane from Winnipeg to Red Deer.
The average speed of the plane from Winnipeg to Red Deer is 400 km/h
What is average speed?Average speed is total distance travelled over total time taken.
What is the average speed of the plane from Winnipeg to Red Deer?Since a plane flew from Red Deer to Winnipeg, a flying distance of 1260 km. On the return journey, due to a strong head wind, the plane travelled 1200 km in the same time it took to complete the outward journey. On the outward journey, the plane was able to maintain an average speed 20 km/hr greater than on the return journey.
Let
v = speed of plane on outward journey , v' = speed of plane return journey and t = time of travelSince the plane travels 1260 km on the outward journey, we have that
1260 = vt (1)
Also, the plane travels 1200 km on the inward journey, we have that
1200 = v't (2)
Since the plane was able to maintain an average speed 20 km/hr greater than on the return journey, we have that
v = v' + 20 (3)
Substituting equation (3) into (1), we have that
1260 = (v' + 20)t (4)
The required equations are
1260 = v't + 20t (4)
1200 = v't (2)
Subtracting equations, (2) from (4), we have that
1260 = v't + 20t (4)
-
1200 = v't (2)
60 = 20t
t = 60/20
t = 3 h
From equation (2), we have that the average speed
v' = 1200/t
Substituting t = 3 into the equation, we have that
v' = 1200/3
v' = 400 km/h
So, the average speed is 400 km/h
