Answer:
135,590.4 lbs
Step-by-step explanation:
the radius of tank = r = 4 ft
the length of tank = h = 42 ft
the volume of tank truck = π. r².h
= 22/7 × 4² x 42
= 132×16
= 2,112 ft³ (= the volume of milk)
so, the weight of milk =
2,112 × 64.2 = 135,590.4 lbs
[tex]\\ \sf\longmapsto V=\pi r^2h[/tex]
[tex]\\ \sf\longmapsto V=\dfrac{22}{7}(4)^2(42)[/tex]
[tex]\\ \sf\longmapsto V=22(16)(6)[/tex]
[tex]\\ \sf\longmapsto V=22(96)[/tex]
[tex]\\ \sf\longmapsto V=2112ft^3[/tex]
Now
Weight of milk
[tex]\\ \sf\longmapsto 2112(64.2)=135,590lbs[/tex]

City officials use the given system of equations to estimate the population of two neighboring communities, where y is the population and x is
the time, in years.
y = 10,000(1.01)
y = 8,000(1.02)
Use this system to complete the statement.
After about _______
A.12
B.22
C.16
D.20
years, the population of each community will be approximately_____
A.18,270
B.14,400
C.16,200
D.11,300
people.
Answer:
After about 22 years, the population of each community will be approximately 12400
Step-by-step explanation:
Given
[tex]y_1 = 10000(1.01)^x[/tex]
[tex]y_2 = 8000(1.02)^x[/tex]
Required
The population of each community after certain years.
[tex](a)\ x = 12[/tex]
We have:
[tex]y_1 = 10000(1.01)^x[/tex] [tex]y_2 = 8000(1.02)^x[/tex]
[tex]y_1 = 10000(1.01)^{12[/tex] [tex]y_2 = 8000(1.02)^{12[/tex]
[tex]y_1 = 11268.25[/tex] [tex]y_2 = 10145.93[/tex]
[tex]y_1 \approx 11300[/tex] [tex]y_2 \approx 10100[/tex]
[tex](b)\ x = 22[/tex]
We have:
[tex]y_1 = 10000(1.01)^{22[/tex] [tex]y_2 = 8000(1.02)^{22[/tex]
[tex]y_1 = 12447.158[/tex] [tex]y_2 = 12367.83[/tex]
[tex]y_1 \approx 12400[/tex] [tex]y_2 \approx 12400[/tex]
[tex](c)\ x = 16[/tex]
We have:
[tex]y_1 = 10000(1.01)^{16[/tex] [tex]y_2 = 8000(1.02)^{16[/tex]
[tex]y_1 = 11725.78[/tex] [tex]y_2 = 10982.28[/tex]
[tex]y_1 \approx 11700[/tex] [tex]y_2 \approx 11000[/tex]
[tex](d)\ x = 20[/tex]
We have:
[tex]y_1 = 10000(1.01)^{20[/tex] [tex]y_2 = 8000(1.02)^{20[/tex]
[tex]y_1 = 12201.90[/tex] [tex]y_2 = 11887.60[/tex]
[tex]y_1 \approx 12200[/tex] [tex]y_2 = 11900[/tex]
Quadratics need help making parabola
Answer:
The equation of the parabola is [tex]y = \frac{1}{3}\cdot x^{2}-\frac{4}{3}\cdot x -4[/tex], whose real vertex is [tex](x,y) = (2, -5.333)[/tex], not [tex](x,y) = (2, -5)[/tex].
Step-by-step explanation:
A parabola is a second order polynomial. By Fundamental Theorem of Algebra we know that a second order polynomial can be formed when three distinct points are known. From statement we have the following information:
[tex](x_{1}, y_{1}) = (-2, 0)[/tex], [tex](x_{2}, y_{2}) = (6, 0)[/tex], [tex](x_{3}, y_{3}) = (0, -4)[/tex]
From definition of second order polynomial and the three points described above, we have the following system of linear equations:
[tex]4\cdot a -2\cdot b + c = 0[/tex] (1)
[tex]36\cdot a + 6\cdot b + c = 0[/tex] (2)
[tex]c = -4[/tex] (3)
The solution of this system is: [tex]a = \frac{1}{3}[/tex], [tex]b = - \frac{4}{3}[/tex], [tex]c = -4[/tex]. Hence, the equation of the parabola is [tex]y = \frac{1}{3}\cdot x^{2}-\frac{4}{3}\cdot x -4[/tex]. Lastly, we must check if [tex](x,y) = (2, -5)[/tex] belongs to the function. If we know that [tex]x = 2[/tex], then the value of [tex]y[/tex] is:
[tex]y = \frac{1}{3}\cdot (2)^{2}-\frac{4}{3}\cdot (2) - 4[/tex]
[tex]y = -5.333[/tex]
[tex](x,y) = (2, -5)[/tex] does not belong to the function, the real point is [tex](x,y) = (2, -5.333)[/tex].
83 less than triple m
Answer:
3m-83
Step-by-step explanation:
Okay, so first, you'd like to triple m. This would mean that it would be m+m+m, which is also 3m. Next you have to subtract 83. This would make it 3m-83.

What is the value of x in the figure? Enter your answer in the box.
145º
(2x + 15)
Answer:
x = 65
Step-by-step explanation:
The angle labeled with the expression " ( 2x + 15 ) " and the angle with the measure of 145° are vertical angles
Vertical angles are congruent (In other words, they are equal to each other)
Hence, 2x + 15 = 145
^ ( Note that we just created an equation that we can use
to solve for x )
Using that same equation we then solve for x
2x + 15 = 145
step 1 subtract 15 from each side
15 - 15 cancels out
145 - 15 = 130
we now have 130 = 2x
step 2 divide each side by 2
130 / 2 = 65
2x / 2 = x
we're left with x = 65

A cylinder has a volume of 2512 cubic feet. If the height of the cylinder is 50 feet, what is the radius of the cylinder? Use 3.14 for pi.
Answer:
4 ft.
Step-by-step explanation:
2512 = 3.14 * r^2 * 50
r^2 = 2512 / (3.14 * 50)
r^2 = 16
r = 4 ft.
A right triangle has legs with lenghts of 7 units and 12 units. What is the area of the triangle?
Answer:
area of triangle =1/2 x b x h
Step-by-step explanation:
=1/2 x 7 x 12
= 1/2 x 84
= 42 units
Which equation can be used to find the unknown length, a, in this triangle?
A right triangle has a side with length 15 meters and hypotenuse with length 17 meters. The other side is labeled a.
a squared + 15 squared = 17 squared
15 squared + 17 squared = a squared
a squared + 15 = 17 squared
a + 15 squared = 17 squared
9514 1404 393
Answer:
(a) a squared + 15 squared = 17 squared
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.
a^2 + 15^2 = 17^2 . . . . . . matches the first choice
Answer:
Solution :-We know that
Base² + Length ² = Hypotenuse²
(a)² + (15)² = 17²
So,
Option A is correct
If we solve it
(a)² + 225 = 289
(a)² = 289 - 225
(a)² = 64
a = √{64}
a = 8

Suppose you are interested in using regression analysis to estimate a student's GPA using the following independent variables: the student is a freshman, the student's ACT score, number of hours per week the student studies, the student's GPA in the previous term, the student's GPA in high school, and the number of classes skipped per week. Which of the following independent variables are indicator (dummy) variables?
a. the student lives on campus
b. the student's parents graduated from college
c. the student's GPA in high school
d. the number of hours spent in class per week
e. the student is dating
f. number of alcoholic drinks per week the student consumes
g. None of these
Answer:
B
Step-by-step explanation:
The options a. the student lives on campus b. the student's parents graduated from e.college Student is dating are dummy variables.
What is dummy variable?Dummy variables are those variables where we use 0 and 1 to represent categorical variables, like yes or no, etc.
student lives on campus is a dummy variable because it can be answered as yes or no
student’s parents graduated from college is a dummy variable because it can be answered as yes or no
Student GPA and number of hours are not dummy because these are not categorical variable
Student is dating is dummy variable because it can be answered as yes or no
number of alcoholic drinks is not dummy variable because it is not categorical variable.
