Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?

Answer:

Minutes = 8 minutes

Step-by-step explanation:

Topic: Inequality

Given:

Available Size of water = 17 liters

Increment = 5 liters/minute

Size of water needed = At least 57 liters

Putting the above together, as have

17 + 5m > 57

where m represents total minutes and > represent at least

Solving the Inequality

5m > 57 - 17

5m > 40 ------ Divide through by 5

5m/5 > 40/5

m > 8

So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.

Step-by-step explanation:

The length of side AB is 15 units.

Given that triangles ADE and ABC are similar, and the length of side AC is 12, the length of side AE is 8 and the length of side AD is 10.

We need to find out the length of side AB.Since triangles ADE and ABC are similar, the corresponding sides are proportional.

Therefore, we have the proportion:AD / AB = AE / AC

So, we can find the length of AB by rearranging the proportion:

AB = AD × AC / AE

Since triangles ADE and ABC are similar, we can use the similarity property to indicate that corresponding sides of similar triangles are proportional.

Let x be the length of side AB.

Knowing the ratio of the corresponding sides, we can establish the ratio:

AE / AB = DE / BC

Substitute the given values:

8 / x = 10 / 12

To solve for x can do cross multiplication.

Solve the resulting equation:

8 * 12 = 10 * x

96 = 10x

Divide both sides by 10:

96 / 10 = x

x = 9.6

Taking the given values:

AB = 10 × 12 / 8AB

= 15

The equation of the line for the given graph is y = - 4x + 110.

1)We can calculate the slope of the given line by,

m = (y2 - y1)/(x2 - x1)

where, (x1, y1) are the initial points and (x2,y2) are the final points of the line.

here, (x1, y1) = (5,90)

and, (x2,y2) = (0,110)

so,

m = (110 - 90)/(0 - 5) = -4

therefore, the equation of the line will be,

y = - 4x + 110

where 110 is the y-intercept of the line

2) Slope is the rate of change of the dependent variable with respect to the independent variable.

Here we can say that the slope shows the decrease in the balance of the savings accounts with respect to the weeks.

We have proved that Angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

To prove that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, we can use the following steps:

Step 1: Join points A and C with a line segment. Let's label the point where AC intersects with line segment BD as point E.

Step 2: Since line segment AC is drawn, we can consider triangle ABC and triangle ADC separately.

Step 3: In triangle ABC, we have angle B + angle ABC + angle BCA = 180 degrees (due to the sum of angles in a triangle).

Step 4: In triangle ADC, we have angle D + angle ADC + angle CDA = 180 degrees.

Step 5: From steps 3 and 4, we can deduce that angle B + angle ABC + angle BCA + angle D + angle ADC + angle CDA = 360 degrees (by adding the equations from steps 3 and 4).

Step 6: Consider quadrilateral ABED. The sum of angles in a quadrilateral is 360 degrees.

Step 7: In quadrilateral ABED, we have angle BAD + angle ABC + angle BCD + angle CDA = 360 degrees.

Step 8: Comparing steps 5 and 7, we can conclude that angle B + angle BCD + angle D = angle BAD + angle ABC + angle ADC.

Step 9: Rearranging step 8, we get angle BCD = angle BAD + angle ABC + angle ADC.

Therefore, we have proved that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

Step-by-step explanation:

To make a 30% alcohol solution, you would need to add 20 liters of 20% alcohol solution to 40 liters of 50% percentage alcohol solution.

50 liters of 50% alcohol solution = 50 liters x 0.50 = 25 liters of pure alcohol

40 liters of 50% alcohol solution = 40 liters x 0.50 = 20 liters of pure alcohol

Total pure alcohol = 25 liters + 20 liters = 45 liters

Required pure alcohol to make a 30% solution = 30 liters

Difference in pure alcohol = 30 liters - 45 liters = -15 liters

Add 20% alcohol solution to make up the difference = -15 liters/0.20 = 75 liters of 20% alcohol solution.

Therefore, 75 liters of 20% alcohol solution should be added to 40 liters of a 50% alcohol solution to make a 30% percentage solution.

THIS is the answer to your question.

By Benjemin

The correct answer is A. s ≠ ±2√(5/3). The solution for x1 and x2 can be found by substituting the value of s into the equations given in the options. To find the values of s for which the system has a unique solution, we need to find the determinant of the coefficient matrix.

To determine the values of the parameter s for which the system has a unique solution, we can use the method of solving a system of linear equations. The given system of equations is:
5sx + 3x2 = 6
8x1 + 2sx2 = -2
To find the values of s for which the system has a unique solution, we need to find the determinant of the coefficient matrix. The determinant is given by:
D = (5s)(2s) - (3)(8) = 10s^2 - 24
For the system to have a unique solution, the determinant D should not be equal to zero. Therefore, we need to solve the equation 10s^2 - 24 ≠ 0.
Simplifying the equation, we get:
10s^2 ≠ 24
s^2 ≠ 2.4
s ≠ ±√(2.4)
So, the correct answer is A. s ≠ ±2√(5/3). The solution for x1 and x2 can be found by substituting the value of s into the equations given in the options.

The composition id_t  f is equal to f, as it preserves the output of the function f for all elements in set s.

Given sets s and t, and a function f: s -> t, we need to prove that id_t  f = f, where id_t is the identity function on set t. The identity function id_t(x) = x for all x ∈ t.

Consider any element x ∈ s. Since f is a function from s to t, f(x) ∈ t. Now, let's apply the composition of id_t and f, denoted as (id_t  f)(x). By definition, (id_t  f)(x) = id_t(f(x)).

Since f(x) ∈ t and id_t is the identity function on t, we have

id_t(f(x)) = f(x).

Therefore, (id_t  f)(x) = f(x) for all x ∈ s.

To prove that idt ◦f = f, we need to understand what each term means. "Function" is a mathematical concept that maps elements from one set to another. "Sets" are collections of objects. "idt" is the identity function, which maps every element of a set to itself.

To prove that idt ◦f = f, we need to show that they have the same mappings. This can be done by applying both functions to each element of set s and comparing the results. By definition of the identity function, we know that idt(x) = x for all x in set t. Therefore, idt ◦f(x) = f(x) for all x in set s. This shows that idt ◦f and f have the same mappings, and thus they are equal.Given that S and T are sets, and f is a function from S to T, denoted by f: S → T, we want to prove that id_T ◦ f = f, where id_T is the identity function on the set T.
Step 1: Define the identity function id_T: T → T. For any element x in T, id_T(x) = x.
Step 2: Recall the composition of functions. If g: T → U and f: S → T, then the composition g ◦ f: S → U is defined as (g ◦ f)(x) = g(f(x)) for all x in S.

Step 3: Prove id_T ◦ f = f. To show this, we need to verify that (id_T ◦ f)(x) = f(x) for all x in S.
For any x in S, (id_T ◦ f)(x) = id_T(f(x)) by definition of composition. Since id_T is the identity function on T and f(x) is an element of T, id_T(f(x)) = f(x). Thus, (id_T ◦ f)(x) = f(x) for all x in S, proving that id_T ◦ f = f.+

The difference quotient of f(x) is \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\) .

According to the given question.

We have a function

f(x) = -1/(5x -12)

As we know that, the difference quotient is a measure of the average rate of change of the function over and interval.

The difference quotient formula of the function y = f(x) is

[f(x + h) - f(x)]/h

Where,

f(x + h) is obtained by replacing x by x + h in f(x)

f(x) is a actual function.

Therefore, the difference quotient formual for the given function f(x)

= [f(x + h) - f(x)]/h

= \(\frac{\frac{-1}{5(x+h)-12} -\frac{-1}{5x-12} }{h}\)

= \(\frac{\frac{-1}{5x + 5h -12}+\frac{1}{5x-12} }{h}\)

= \(\frac{\frac{-1+5h}{5x + 5h-12} }{h}\)

= \(\frac{-1+5h}{(5x +h-12)(h)}\)

= \(\frac{-1+5h}{5xh + h^{2} -12h}\)

= \(\frac{h(-\frac{1}{h}+5) }{h(5x+h-12)}\)

= \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\)

Hence, the difference quotient of f(x) is \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\) .

The probability of throwing an odd number with a normal dice is 1/2

When rolling a normal six-sided B, there are six equally likely outcomes: 1, 2, 3, 4, 5, and 6. Out of these six numbers, three of them (1, 3, and 5) are odd numbers. Thus, there are three favorable outcomes (odd numbers) out of a total of six possible outcomes.

To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes. In this case, the probability of throwing an odd number is 3/6, which simplifies to 1/2.

This means that there is a 50% chance of rolling an odd number with a normal six-sided die. In other words, if you roll the die many times, you can expect that approximately half of the outcomes will be odd numbers.
