Answer 1

Answer: B

So the question is asking when it will be the same amount of water, which means we are dealing with an EQUAL sign because they want to know when it’s the SAME. So, we look at the equation again and it’s saying that the 4.5 gallon tub is gaining water, and the 7 gallon tub is losing water. Because C also has an equal sign, it isn’t the right choice because of the fact that the 7 gallon tub in that equation has a + sign instead of a - sign like B does.

Answers

For the given quadratic function we have that:

Domain: Set of all real values.Range: y ≤ 3.

What is the domain and range of the quadratic function?

For a function h(x), we define the domain as the set of the inputs (values of x) and the range is the set of the outputs (values of y).

Generally, for all quadratic functions, the domain is the set of all real numbers, so we already know the domain.

Now let's look at the range.

The given function is:

h(x) = -12*(x - 4)^2 + 3

Remember that if a quadratic function has a vertex (h, k), then the vertex form is:

f(x) = A*(x - h)^2 + k

So the vertex here is (4, 3)

And we also can see that the leading coefficient of the quadratic function is negative. This means that the function opens downwards, so the vertex is the maximum.

Then the range is the set of all real values smaller than or equal to 3, then the range is:

R: y ≤ 3.

Concluding:

Domain: Set of all real values.Range: y ≤ 3.

a list of measurements in increasing order is 4, 5, 6, 8, 10, and x . if the median of these measurements is six sevenths times their arithmetic mean, what is the value of x ?

Answers

In a list of measurements in increasing order: 4, 5, 6, 8, 10, and x, the value of x is 16.

To get the value of x, we will use algebraic expressions to demonstrate the given relationships.

If the median of these measurements is six sevenths times their arithmetic mean, then:

median = 6/7 x mean

Median (Md), is a single value at the middle of the data values arranged in increasing or decreasing order. On the other hand, arithmetic mean (μ) is the sum of the data values divided by its total number.

For the list of measurements in increasing order is 4, 5, 6, 8, 10, and x,

The median is between 6 and 8.

Md = 6+8/2

Md = 7

Evaluating the first equation using Md = 7:

median = 6/7 x mean

7 = 6/7 x mean

mean = 49/6

By definition,

mean = (4 + 5 + 6 + 8 + 10 + x)/6

Equating both equations for the mean:

49/6 = (4 + 5 + 6 + 8 + 10 + x)/6

49 = 33 + x

x = 16

Hence, the value of x is 16.

select translation, reflection, or rotation to identify the single transformation that transforms ∆rst to ∆r′s′t′.

Answers

The single transformation that transforms ∆RST to ∆R'S'T' is a reflection.

Part A:

For the first figure it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.

Part B:

For the second figure ,it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down and a few units to the right. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.

Part C:

For the third figure it is visible that the orientation of the pre-image (∆RST) isn't similar to that of the image (∆R'S'T').The image is received from the pre-image through rotating the pre-image a few 180 degrees. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a rotation.

Part D:

For the fourth figure it is visible that the orientation of the pre-image (∆RST) isn't similar to that of the photograph (∆R'S'T').The image is received from the pre-image through reflecting the pre-image.

Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a reflection.

with full process

Answers

A 25% rate of interest is required for Rupees 4000 amount to Rupees 6000 in 2 years.

Here we are given the following-

Principal amount = Rs 4000

Amount received after 2 years = Rs 6000

Time period = 2 years

Let the rate of interest = r%

Then, according to the simple interest formula-

Simple interest = Principal × time period × rate/100

and Simple interest = Final amount - principal amount

Here, simple interest = 6000 - 4000 = Rs 2000

Thus,

2000 = 4000 × 2 × r/100

2000/4000 = 2 × r/100

1/2 = 2 × r/100

1/4 = r/100

r = 100/4

what percent of 54 is 23? explained

Answers

Answer: 42.59

Step-by-step explanation:

Step 1: First, write the problem as an equation: P% = X/Y

Step 2: Here, X is 23, Y is 54, so the equation is P% = 23/54

Step 3: A percent is a ratio of a number expressed out of 100. So P% means P/100

Step 4: Substitute P/100 instead of P% in the above equation, then P% = 23/54 becomes P/100 = 23/54

Step 5: Solve for P

P/100 = 23/54

P = (23/54) * 100 = 42.59

Therefore, 23 is 42.59 percent of 54

If it takes my car 2.2 seconds to accelerate from 8.9 m/s to 35.76 m/s, what is my cars average acceleration in that time?

Answers

Your cars average acceleration in that time is 12.21m/s^2

What is my cars average acceleration in that time?

The given parameters are

Initial velocity, u = 8.9 m/s

Final velocity, v = 35.76 m/s

Time, t - 2.2 seconds

The average acceleration is calculated using

v = u + at

So, we have

35.76 = 8.9 + 2.2a

Evaluate the like terms

26.86 = 2.2a

Divide by 2.2

a = 12.21

Hence, your cars average acceleration in that time is 12.21m/s^2

For a certain performance the theater sold 5 times as many lower level tickets as upper balcony tickets. The theater sold $37,500 in tickets for that performance. The money made from mezzanine tickets alone was 4 times the money made from upper balcony tickets. How many lower level tickets were sold for that performance?

Answers

Based on the calculation done below, the number of lower level tickets sold is 750.

How do we calculate the number of units sold from a word problem?

Let:

L = number of lower-level tickets sold = 5U

M = number of mezzanine tickets sold

U = number of upper balcony tickets sold

We therefore have:

35L + 25M + 15U = 37,500 ...................... (1)

25M = 4 * 15U = 60U

Substituting L = 5U and 25M = 60U into equation (1) and solve for U, we have:

35(5U) + 60U + 15U = 37,500

175U + 60U + 15U = 37,500

250U = 37,500

U = 37,500 / 250

U = 150

Susbstituting U = 150 into L = 5U, we have:

L = 5 * 150
