A cylindrical chemical tank is 12 feet high and has a diameter of 45 feet. How many cubic feet of
liquid could the tank hold?

Step-by-step explanation:

B = 0.08 - 0.016N

N = 3 hours 15 minutes = 3.25 hours (= 3 1/4).

so, we get

B = 0.08 - 0.016×3.25 = 0.08 - 0.052 = 0.028

Therefore 5 + 4 × (14 - 4) - 8 = 37

Answer: A.

Step-by-step explanation:

The extraneous solution is the value of the independent variable for which the problem has no solution. x=3 is an extraneous solution.

An extraneous solution is a solution that develops from the process of addressing the problem but is not a real solution to the problem, such as an equation.

In order to know the extraneous solution, we need to find the value of x in the given equation,

[tex]\rm log_4(x)+log_4(x-3)= log_4(-7x+21)[/tex]

Using the logarithmic property,

[tex]\rm log_4[x(x-3)]= log_4(-7x+21)[/tex]

Taking the anti-log, we will get,

[tex]x(x-3)= -7x+21\\\\x^2-3x=-7x+21\\\\x^2+7x-3x-21=0\\\\x(x+7)-3(x+7)=0\\\\(x-3)(x+7)=0[/tex]

If we substitute the factors with the 0, we will get the value of x as 3 and -7.

We know that extraneous solutions are those solutions, which when substituted in the initial equation, the equation does not return an equation.

x=3

[tex]\rm log_4(x)+log_4(x-3)= log_4(-7x+21)[/tex]

[tex]\rm log_4(x3)+log_4(3-3)= log_4(-21+21)\\\\\rm log_4(x)+log_4(0)= log_4(0)[/tex]

As the value of logₐ(0) is undefined, therefore, x=3 is an extraneous solution.

A convergent series is a series whose partial sums tend to a specific number or a limit.

Example: [tex]3+1+\frac{1}{3}+\frac{1}{9}+.~.~.[/tex]

This is because a series is convergent if

[tex]-1 < r < 1[/tex]

where r is the common ratio

and for the question above

[tex]r=\frac{1}{3}[/tex]

A divergent series is a series whose partial sums do not approach a limit. Divergent series typically go to positive infinity, negative infinity, or don't approach a specific number.

Answer:

R90

Step-by-step explanation:

120 hats sold and each = $0.50

0.50 × 120 = R60 (all the baseball hats cost)

50% of 0.50 = 0.25

0.25 × 120 = 30 (markup price)

60 + 30 = 90 ( total received for the sales)

Answer:

it will take the second crocodile 60 seconds

The time it will take the second crocodile to finish it's snack is; 120 s

Let x represent the rate of the first crocodile and let y represent the rate of the second crocodile.

The two crocodiles working together can finish a snack in 40 seconds. Thus;

(1/x + 1/y)40 = 1

It takes one of the crocodiles 60 seconds to finish it's snack. Thus;

(1/x + 1/60)40 = 1

40/x + 2/3 = 1

x = 120 seconds

r = sqrt(16/pi)

Step-by-step explanation:

Cylinder formula = r^2 x pi x height

176 pi/11pi = 16

16 = r^2 x pi

16/ pi = r^2

r = sqrt(16/pi)

This is just the number of permutations of the set {0, 0, 0, 1, 1, 1, 2, 2, 2}. There are 9 elements in the set, so there are 9! = 362,880 possible ternary strings with exactly 3 each of 0, 1, and 2.

Answer:

B. [tex]x^2+11x+24\leq 150[/tex]

Step-by-step explanation:

Step 1) Defining Sue and Jeremy's ages using x

Sue is 3 years older than Holly (h):

[tex]h=x+3[/tex]

Jeremy is 5 years older than Sue, or 8 years older than Holly (j):

[tex]j=x+8[/tex]

Product of Jeremy and Sue's ages is less than or equal to 150:

[tex]hj\leq 150[/tex]

Step 2) Simplifying into a single equation

Using the equation above we can substitute Sue and Jeremy's ages:

[tex](x+3)(x+8)\leq 150[/tex]

Now we can simplify this equation. Use the distributive property first:

[tex]x(x+8)=x^2+8x\\3(x+8)=3x+24[/tex]

Now add all the terms together and get the final answer:

[tex]x^2+8x+3x+24\leq 150\\x^2+11x+24\leq 150[/tex]

Final equation: [tex]x^2+11x+24\leq 150[/tex]

If the value of x increases then the value of y decreases. Then the correct option is B.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

For the inverse variation function

[tex]\rm y = \dfrac{k}{x}[/tex]    (where x, k > 0),

We know that the y is inversely proportional to the x.

Thus, if the value of x increases then the value of y decreases.

Therefore, the correct option is B.

The number of unit tiles needed to be added to the expression [tex]x^2 + 4x + 3[/tex] for making it perfect square trinomial is: Option A: 1

If a polynomial p(x) can be written as:

[tex]p(x) = [f(x)]^2[/tex]

where f(x) is also a polynomial, then p(x) is called as perfect square polynomial.

Terms are added or subtracted to make a polynomial. They're composed of variables and constants all in multiplication.

Example: [tex]x^2 + 3x + 4[/tex] is a polynomial consisting 3 terms as [tex]x^2 ,3x , \rm and \: 4[/tex]

The given trinomial is [tex]x^2 + 4x + 3[/tex]

Since the tiles are added to be in unit and positive(1, 2, 3, or 4), thus, let it be denoted by z, then:

[tex]x^2 + 4x + 3 + z = (x+a)^2[/tex]

since z is added such that the specified trinomial becomes perfect square trinomial, and since its degree is 2, so it must be product of two linear polynomials, and since coefficient of x in given trinomial is 1, so we kept the coefficient of linear polynomial as 1

Now, expanding the obtained equation, and comparing the coefficients, we get:

[tex]x^2 + 4x + 3 + z = (x+a)^2\\x^2 + 4x + 3 + z = x^2 + a^2 + 2ax\\[/tex]

Thus, from comparison of coefficients of like terms and constants, we get:

[tex]2a = 4\implies a = 2\\3 + z = a^2 = 2^2 = 4\\z = 1[/tex]

Thus, the number of unit tiles needed to be added to the expression [tex]x^2 + 4x + 3[/tex] for making it perfect square trinomial is: Option A: 1

Quadratic formula: [tex]\frac{-b +-\sqrt{b^{2} - 4ac } }{2a}[/tex]

Step-by-step explanation:

We have -0.08t² + 1.6t + 2 = 9

Subtract 9 from both sides

-0.08t² + 1.6t + 2 = 9

                      - 9   - 9

-0.08t² + 1.6t - 7 = 0

We will have to use the quadratic formula

a = -0.08

b = 1.6

c = -7

[tex]\frac{-1.6 +-\sqrt{1.6^{2} - 4(-0.08)(-7) } }{2(-0.08)}[/tex]

[tex]\frac{-1.6 +-\sqrt{2.56 - 2.24 } }{-0.16}[/tex]
