A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can bee loaded into the container is 26000 kilograms. Other shipments weighing 11300 kilograms have already been loaded into the container. Write an inequality representing c, the total number of 150-kilogram crates that can be loaded into the shipping container
An inequality representing c, the total number of 150-kilogram crates that can be loaded into the shipping container: c ≤ 98
We know that an inequality is a mathematical statement that represents the inequalities between two algebraic expressions with two variables .
It is an unequal relation between two algebraic expressions.
Here, the greatest weight that can be loaded into the container = 26,000 kilograms
the weight of each crate = 150 kilogram
and the weight of other shipment = 11300 kilograms
Let c be the total number of 150-kilogram crates that can be loaded.
So, we get an inequality:
150 c + 11300 ≤ 26,000
150 c ≤ 26,000 - 11300
150 c ≤ 14700
c ≤ 98

Evaluate each of the following expressions given that: f ( x ) = √ x + 5 f(x)=x+5 g ( x ) = 3 x − 7 g(x)=3x-7 h ( x ) = 5x(x)=5x f ( g ( 5 ) ) = f(g(5))= Preview g ( f ( 78 ) ) = g(f(78))= Preview h ( g ( f ( 2 ) ) ) = h(g(f(2)))=
Given the expressions, f(x)=√x+5, g(x)=3x-7, and h(x)=5x, the answer to f(g(5)) is 8. This is because when g(5) is substituted into f(x) we get f(g(5))=f(3x-7)=√(3x-7)+5. When 5 is substituted for x, this simplifies to f(g(5))=√(-2)+5 which equals 8.
The answer to g(f(78)) is 60. This is because when 78 is substituted into f(x) we get f(78)=√78+5 which simplifies to f(78)=9. When 9 is substituted into g(x) we get g(f(78))=3x-7 which simplifies to g(f(78))=3(9)-7 which equals 60.
Finally, the answer to h(g(f(2))) is 83. This is because when 2 is substituted into f(x) we get f(2)=√2+5 which simplifies to f(2)=3. When 3 is substituted into g(x) we get g(f(2))=3x-7 which simplifies to g(f(2))=3(3)-7 which equals 8. When 8 is substituted into h(x) we get h(g(f(2)))=5x which simplifies to h(g(f(2)))=5(8) which equals 83.
In summary, the answers to f(g(5)), g(f(78)), and h(g(f(2))) are 8, 60, and 83 respectively.

Find the length of the prism
The length of the rectangular prism is 4/5x.
What is a rectangular prism?
Six faces make up the three-dimensional shape of a rectangular prism (two at the top and bottom and four are lateral faces). The prism has rectangular shapes on each of its faces. There are therefore three sets of identical faces in this picture. A cuboid is another name for a rectangular prism because of its shape.
We know that Volume of a rectangular prism is a product of length, height and width.
We are given volume as (7/x)-(3/5x).
The width(w) is 2/x and the height(h) is 4/x
Using the formula, we get
⇒ V = lwh
⇒ (7/x)-(3/5x) = l * (2/x) * (4/x)
⇒ l = [(7/x)-(3/5x)] / [(2/x) * (4/x)]
⇒ l = (32/5x) /(8/x^2)
⇒ l = 4/5x
Hence, the length of the rectangular prism is 4/5x.

Answer: Please see explanation column for answer.
x= -36
Step-by-step explanation:
Step 1
from the attachment, Carlo solving is given as
1/3 (1/2x- 9) = 1/2 (x+18)
1/6x-3= 1/2x+9
1/4x-3=9
1/4x=12
x=48
Carlos error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.
Solving correctly, we have that
1/3(1/2x-9) = 1/2(x+18)
1/6x -3= 1/2x+ 9
taking like terms to like terms
1/6x-1/2x= 9+3

-2/6x= 12
-1/3x= 12
multiplying both sides by -3

Calculate the theoretical mass of precipitate produced if calcium chloride solution was reacted with excess sodium bicarbonate
If the reaction was done with excess sodium bicarbonate, the amount of calcium chloride would determine the amount of precipitate produced.
The theoretical mass of precipitate produced in a reaction between calcium chloride and sodium bicarbonate can be calculated by using the balanced chemical equation for the reaction. The balanced equation for this reaction is given as follows:
CaCl₂ + NaHCO₃ → CaCO₃ + NaCl + H₂O
In this reaction, one mole of calcium chloride reacts with one mole of sodium bicarbonate to produce one mole of calcium carbonate precipitate, one mole of sodium chloride solution, and one mole of water.
The mass of the precipitate can be calculated by multiplying the molar mass of calcium carbonate by the number of moles of calcium carbonate produced.
So, to calculate the theoretical mass of precipitate produced, you need to know the amount (in moles) of calcium chloride and sodium bicarbonate used in the reaction. If the reaction was done with excess sodium bicarbonate, the amount of calcium chloride would determine the amount of precipitate produced.

The selling price is then determined by deducting the discount (44) from the marked price (220):

we can by elimination if we multiply the second inequality by -2.5, we get:
-2.50x - 2.5y ≥ -35
if we add the first inequality to the above we get:
2.50x + 1.25y ≤ 30
+ -2.50x - 2.5y ≥ -35
-1.25y = -5
divide each side by -1.25 to get:

Find an equation of the plane through the point and perpendicular to the given line. (-2, 9, 10) x = 5 + t, y = 3t, z = 4 - 3t
Let A be the point (-2, 9, 10) and n be the normal vector of the plane. The direction vector of the line is <1, 3, -3>, and since the plane is perpendicular to the line, n is orthogonal to the direction vector.
So, n is a vector that satisfies:
n . <1, 3, -3> = 0
The equation of the plane can be written in the form:
n . (x - A) = 0
Where x = (x, y, z) is any point in the plane.
We can find n by taking the cross product of two non-parallel vectors in the plane, such as <1, 0, 0> and <0, 1, 0>. Then,
n = (1, 0, 0) x (0, 1, 0) = (0, 0, 1)
Substituting the values of A and n into the equation of the plane, we get:
0 . (x - (-2, 9, 10)) = 0
0 . (x + 2, y - 9, z - 10) = 0
z - 10 = 0
z = 10
So the equation of the plane is:
z = 10
