Answer:

she ate about 2.5 fruit cups each day

Step-by-step explanation:

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]

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:

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

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.

Answer:

B. 8

Step-by-step explanation:

Based on the tangent theorem, when two tangents meet at an external point of a circle, the length of the two tangents are said to be equal in length.

Therefore:

JK = JM

Substitute

5x - 12 = x + 4

Collect like terms

5x - x = 12 + 4

4x = 16

4x/4 = 16/4

x = 4

✔️JK = 5x - 12

Plug in the value of x

JK = 5(4) - 12

JK = 20 - 12

JK = 8

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 \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]

Answer:

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.

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.

Answer: the answer is 8 because

Step-by-step explanation:

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

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].
