Charlie has more than 50 game coins Charlie has 8 more than 3 times as game coins as Steven if x represents the number of game coins Steven has which inequality can be used to determine the possible number of game coins Steven has

==================================================

Explanation:

Let's solve (x-2)(x-5) = 0 and doing so leads to x = 2 or x = 5. Plugging either value in for x makes the expression (x-2)(x-5) become 0.

Let's pick a value to the left of x = 2, let's say we pick x = 0. Plug this into the expression (x-2)(x-5) and we get the following:

(x-2)(x-5)

(0-2)(0-5)

(-2)(-5)

10

The result is a positive number, meaning that (x-2)(x-5) is positive when we select a value smaller than 2.

Now we'll repeat this with a value between 2 and 5. Let's say we pick on x = 3.

So,

(x-2)(x-5)

(3-2)(3-5)

(1)(-2)

-2

The result is negative, so (x-2)(x-5) is negative when 2 < x < 5. This immediately rules out choices C and E.

Unfortunately, answer choices B and D won't work either for similar reasoning. The only thing left is choice A.

Side note: The answer in interval notation is [tex](-\infty, 2] \cup [5, \infty)[/tex] so basically it's everything but values between 2 and 5; however, x = 2 and x = 5 are part of the solution set.

Another side note: if you flip the inequality sign from [tex]\ge[/tex] to [tex]\le[/tex], then the answer would be choice C.

Answer:

The number of

Single scoop cones = s = 9

Double scoop cones = d = 6

Step-by-step explanation :

Let t he number of

Single scoop cones = s

Double scoop cones = d

A single-scoop cone was $3 and a double-scoop cone was $5. The coach bought 15 cones and paid $57.

The system of equation

= s + d = 15.. Equation 1

s = 15 - d

3s + 5d = 57.... Equation 2

We substitute 15 - d for s

3(15 - d) + 5d = 57

45 - 3d + 5d = 57

Collect like terms

- 3d + 5d = 57 - 45

2d = 12

d = 12/2

d = 6

Solving for s

s = 15 - d

s = 15 - 6

s = 9

Therefore,

The number of

Single scoop cones = s = 9

Double scoop cones = d = 6

Answer:

The definite integral expressing the total quantity of oil, 'V', which leaks out of the tanker in the first hour is given as follows;

[tex]V = \int\limits^{60}_0 {A \cdot e^{(-k \cdot t)}} \, dt[/tex]

Step-by-step explanation:

From the question, we have;

The rate at which oil leaks out of the tanker, r = f(t)

The unit of the oil leak = Liters per minute

The unit of t = Minutes

[tex]If \ f(t) = A \cdot e^{(-k \cdot t )}[/tex]

Therefore, we have;

The definite integral expressing the total quantity, 'V', of oil which leaks out of the tanker in the first hour is given as follows;

[tex]V = \int\limits^{60}_0 {A \cdot e^{(-k \cdot t)}} \, dt[/tex]

Therefore, we have;

[tex]\int\limits^{60}_0 {A \cdot e^{(-k \cdot t)}} \, dt = \dfrac{A \cdot e ^{60 \cdot k} - A}{k \cdot e ^{60 \cdot k} }[/tex]

Answer:

1:9

Step-by-step explanation:

First Rectangle:

width x height = area

4 * 5 = 20

Second Rectangle:

(4*3)*(5*3)=x

12 * 15 = 180

Ratio:

180/20 = 90

1:9

Answer:

1:9 or 1/9

Step-by-step explanation:

if a rectangle is 5cm × 4cm

Area of rectangle= length ×width

= 5 × 4

=20cm²

if we triple dimensions of a rectangle we get the second rectangle

therefore, (5×3)cm × (4×3)cm

Area of second rectangle= 12 ×15

=180cm²

ratio is 20/180= 1/9 (Ans.)

24Answer:

Step-by-step explanation:

Rectangle area = length × width

Rectangle area = ( 7x - 2 )( 3x + 4 )

Rectangle area = 21x^2 + 22x - 8

Thus the correct answer is option D .

Answer:

Step-by-step explanation:

Let s represent the length of each of the three sides mentioned.  The length of the fourth side is 7 inches.  Adding the lengths of the four sides together yields 10 inches:  g + g + g + 7 = 10 (inches)

Then 3g + 7 = 10, or 3g = 3, or g = 1.  

This equation is OK, but there's no solution, since 3g or just 3 is less than 7.  With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.

Answer:

33.33%

Step-by-step explanation:

The line of best fit for the data is represented by the equation y = 3x + 15.

At x = 4,

y = 3(4) + 15 = 27

At x = 7,

y = 3(7) + 15 = 36

We need to find the percent change in the total number of trees from x = 4 to x = 7.

So,

[tex]\%=\dfrac{36-27}{27}\times 100\\\\=33.33\%[/tex]

So, the required percentage change is equal to 33.33%.

Answer: (a) [tex]\dfrac{5}{24}[/tex]

Step-by-step explanation:

Given: Fraction of section of land = [tex]\dfrac{5}{6}[/tex]

Fraction of corn planted on land = [tex]\dfrac14[/tex]

The fraction of the entire section is planted with Margaret’s corn =

[tex]\dfrac{5}{6}\times\dfrac{1}{4}\\=\dfrac{5}{24}[/tex]

The correct option is (a).

The fraction of the entire section is planted with Margaret’s corn = [tex]\dfrac{5}{24}[/tex]

Answer:

The angle between the two vectors

∝ = 64°

Step-by-step explanation:

Step(i):-

Given that the vectors

                           [tex]a^{-} = i^{-} - 2j^{-} +5k^{-}[/tex]

          and

                         [tex]b^{-} = 3i^{-} +j^{-} -2k^{-}[/tex]

[tex](a^{-} . b^{-} ) = (i^{-} - 2j^{-} +5k^{-} ) . (3 i^{-} + j^{-} - 2k^{-} )[/tex]

           =  3 (i⁻ . i⁻) - 2(j⁻.j⁻) -10(k⁻.k⁻)

          = 3 - 2 -10

          = -9

Step(ii):-

Let '∝' be the angle between the two vectors

                    [tex]cos\alpha = \frac{a^{-}.b^{-} }{|a||b|}[/tex]

                  [tex]cos\alpha = \frac{|-9| }{\sqrt{1+4+25}\sqrt{9+1+4} }[/tex]

                 [tex]cos\alpha = \frac{|-9| }{\sqrt{30}\sqrt{14} }[/tex]

               [tex]\alpha =cos^{-1} ( \frac{|-9| }{\sqrt{30}\sqrt{14} })[/tex]

              ∝ = cos⁻¹(0.4392) = 63.947

Final answer:-

The angle between the two vectors

               ∝ = cos⁻¹(0.4392) = 63.947

                ∝ = 64°

Answer:

cube

Step-by-step explanation:

The shape in the middle of the two rectangular prism would be a cube. This is the case since the angle at the base of the rectanglular prism forms a 90-degree angle. This indicates that the line is a straight line and would also form a 90-degree angle with the bottom angles as well. This would ultimately indicate that it forms a square, and since the shape is a 3-Dimensional shape it would be classified as a cube in this image.

Answer:

Triangular Prism

Step-by-step explanation:

The middle shape is a rectangular prism.

The top and bottom is a Triangular Prism.
