the scoop of an excavator holds 26 ft³of sand. if the capacity of a freight car is 39 tons of sand and we know that 1 ft³ of sand weighs 0.05 ton how many freight cars can be filled with 120 scoops?
Answers
Answer:
4!
Step-by-step explanation:
its 0.05 not 0.5! instead of it being 40, its 4
4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.
What do we mean by volume or capacity of a substance?In three-dimensional space, volume refers to the entire amount of space occupied by an item. Capacity refers to an object's capacity to contain, absorb, or accept anything (such as a solid material, gas, or liquid).
What do we mean by the mass of a substance?The amount of matter in a substance or object is measured by its mass.
How do we solve the given question?In the question, we are given that the scoop of an excavator holds 26 ft³of sand.
We are asked if the capacity of a freight car is 39 tons of sand, then how many freight cars can be filled with 120 scoops.
We are also informed that 1 ft³ of sand weighs 0.05 tons.
We first find the mass of sand in one scoop of an excavator.
The volume of sand in one scoop of an excavator = 26 ft³.
Mass of 1 ft³ of sand = 0.05 tons.
∴ Mass of 26 ft³ of sand, that is, the mass of sand in one scoop of an excavator = 26*0.05 tons = 1.3 tons.
∴ Mass of 120 scoops = 120*1.3 tons = 156 tons.
The capacity of one freight car = 39 tons
∴ Number of freight cars in 156 tons = 156/39 = 4.
∴ 4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.

Step-by-step explanation:
*Note:
The problem is too big to fit all work. I will assume that you know how to do basic calculus.
Step 1: Define
Identify given.
[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx[/tex]
Step 2: Integrate Pt. 1
[Integrand] Rewrite:[tex]\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \leftarrow \\\end{aligned}[/tex]
Step 3: Integrate Pt. 2
Identify variables for u-substitution.
Set u:[tex]\displaystyle u = x + e[/tex][u] Differentiate [Derivative Rules and Properties]:
[tex]\displaystyle du = dx[/tex]
Step 4: Integrate Pt. 3
[Integral] Apply Integration Method [U-Substitution]:[tex]\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \\& = \int\limits^{x = 1}_{x = 4} {\frac{(u - e) \cos (u - e)}{u} \, du \leftarrow \\\end{aligned}[/tex][Integral] Rewrite [Integration Property - Addition/Subtraction]:
[tex]\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^1_4 {\frac{x \cos x}{x + e} \, dx \\& = \int\limits^{x = 1}_{x = 4} {\frac{(u - e) \cos (u - e)}{u} \, du \\ & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - \int\limits^{x = 1}_{x = 4} {\frac{e \cos (u - e)}{u}} \, du \leftarrow \\\end{aligned}[/tex][2nd Integral] Rewrite [Integration Property - Multiplied Constant]:
[tex]\displaystyle \begin{aligned}\int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \leftarrow \\\end{aligned}[/tex]
Step 5: Integrate Pt. 4
Identify variables for u-substitution for the 1st integral.
Use another variable besides u to avoid confusion with earlier substitutions.
Set v:[tex]\displaystyle v = u - e[/tex][v] Differentiate:
[tex]\displaystyle dv = du[/tex]
Step 6: Integrate Pt. 5
Solve the 1st integral using basic integration techniques listed under "Calculus":
[tex]\displaystyle \begin{aligned}\int\limits^{x = 1}_{x = 4} {\cos (u - e)} \, du & = \int\limits^{x = 1}_{x = 4} {\cos v} \, dv \\& = \sin v \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (u - e) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (x) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin 1 - \sin 4\end{aligned}[/tex]
Step 7: Integrate Pt. 6
To solve the 2nd integral, we use the same methods as "Step 6":
[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \int\limits^{x = 1}_{x = 4} {\frac{\sin e \sin u + \cos e \cos u}{u}} \, du \\& = \sin e \int\limits^{x = 1}_{x = 4} {\frac{\sin u}{u}} \, du + \cos e \int\limits^{x = 1}_{x = 4} {\frac{\cos u}{u}} \, du \\& = \sin (e) \text{Si} (u) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (u) \bigg| \limits^{x = 1}_{x = 4} \\\end{aligned}[/tex]
[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \sin (e) \text{Si} (x + e) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (x + e) \bigg| \limits^{x = 1}_{x = 4} \\& = \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) \bigg] + \bigg[ \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\\end{aligned}[/tex]
Step 8: Integrate Pt. 7
Combine our 2 integral values to obtain a final answer:
[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \\\begin{aligned}& = \sin 1 - \sin 4 - e \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) + \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\& \approx \boxed{0862854} \\\end{aligned}[/tex]
∴ we have evaluated the given special definite integral.

Here are the coordinates for the square on the left:

F (-4,4)
T (-2,4)
Here are the coordinates for the window on the right:
R (4,2)
I (2,2)
G (4,4)
H (2,4)
To find the scale factor of 2, you multiply the x and y values by 2.
Left window:
L: -4x2= -8 , 2x 2= 4
L = (-8, 4)
E: -2 x 2= -4 , 2x 2= 4
E = (-4, 4)
F: -4 x 2= -8 , 4 x 2= 8
F = (-8, 8)
T: -2 x 2= -4 , 4 x 2= 8
T = (-4, 8)
Right window:
R: 4 x 2= 6, 2 x 2= 4
R = (6, 4)
I : 2 x 2 = 4, 2 x 2= 4
I = (4, 4)
G: 4 x 2= 8 , 4 x 2= 8
G = (8, 8)
H: 2 x 2= 4 , 4 x 2= 8
H = (4, 8)
These are all of the coordinates for the increases sizes of your windows. All you have to do now is graph them.

Answers
Answer:

Step-by-step explanation:
so if she has $65 and she spent 38.50 you find the difference which is $26.50 then you divide it by 4 which is 6.62 so yes your right its 6 if you round it
Answer:
6 boxes.
Step-by-step explanation:
65 ≥ 38.50 + 4x where x is the number of boxes of mints.
65 - 38.50 ≥ 4x
(65-38.40/ 4 ≥ x
x ≤ 6.625

Geometry and measurement
Answers
Answer:
61/2
Step-by-step explanation:
Solve for the missing variables. (Geometry)
Answers
Step-by-step explanation:
we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.
in other words
h² = p×q
h = height
p, q are the 2 segments of the Hypotenuse.
so, in our case we have
100 = x(x + 21) = x² + 21x
that gives us the following quadratic equation
x² + 21x - 100 = 0
the general solution to a quadratic equating is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 21
c = -100
so,
x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =
= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =
= (-21 ± 29)/2
x1 = (-21 + 29)/2 = 8/2 = 4
x2 = (-21 - 29)/2 = -50/2 = -25
x2 would give us negative lengths for the triangle, which does not make sense.
so, x = 4 is our solution.
that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).
