Answer: The amount you would pay (including tax) for the item is:

$755.37 + $52.88 = $808.25

Step-by-step explanation: irst, we calculate the amount of discount that is applied to the original price:

30% of $1199 = 0.3 x 1199 = $359.70

So, the discounted price is:

$1199 - $359.70 = $839.30

Next, we apply the additional 10% off coupon to this discounted price:

10% of $839.30 = 0.1 x $839.30 = $83.93

The final price after the coupon is applied is:

$839.30 - $83.93 = $755.37

Finally, we calculate the sales tax on this final price:

7% of $755.37 = 0.07 x $755.37 = $52.88

The amount you would pay (including tax) for the item is:

$755.37 + $52.88 = $808.25

Answer:

Check the picture below.

Answer:

∠ U = 12°

Step-by-step explanation:

the inscribed angle RST is half the measure of its intercepted arc RT , then

arc RT = 2 × ∠ RST = 2 × 30° = 60°

the secant- tangent angle U is equal to half the difference of its intercepted arcs, that is

∠ U = \(\frac{1}{2}\) ( RS - RT ) = \(\frac{1}{2}\) × (84 - 60)° = \(\frac{1}{2}\) × 24° = 12°

The shape that's given illustrates that the number of bricks that are needed will be 200.

From the information given, the bricks are 25 cm long and 6 cm wide and will be required to cover a path of dimension 250cm by 120 cm.

Therefore, the number of bricks required will be:

= (120 × 250) / (25 × 6)

= 200

In conclusion, the correct option is 200.

The reasonable domain for the function is (b) x > 0

From the question, we have the following parameters that can be used in our computation:

The function f(x) = 75x + 100

Where x is the number of hours

f(x) is the total cost.

In this case, the number of hours cannot be negative or 0

This means that the values of x in the function would be x > 0

These values of x are the domain

Mathematically: it is an  algebraic equations that can be also  written in the form of  ax + b = 0 or ax + by + c = 0, where a, b and c are definitely real numbers and x and y are variables with the highest power one.
In order to solve this problem, we must set up a proportion. Proportions are an equation that states that two ratios are equal. In this case, we are looking for the number of cats (c) in the animal shelter.

Let's set up the proportion.

5/3 = 25/c

We can then solve for c by multiplying both sides by c.

5c/3 = 25

c = 15

The graph of the given equation is attached below.

We are given the equation:-

y = 4x - 1

First we will find the x and y intercepts of the line.

Putting x = 0 to find the y-intercept of the graph, we get

y = 4*0 - 1

y = -1

Hence, the coordinates of the point will be (0,-1).

Putting y = 0 to find the x-intercept of the graph, we get

0 = 4x - 1

1 = 4x

x = 1/4

Hence, the coordinates of the point will be (1/4,0).

My plotting these coordinates on the graph and then joining the line passing through it, we will get our desired graph.

Answer: 172 ounces

Step-by-step explanation:

We are given 10 pounds and 12 ounces to convert to ounces.

There are 16 ounces in 1 pound.

We can create a proportion to find out how much ounces 10 pounds is.

10 pounds / x ounces = 1 pound / 16 ounces

We need to solve for x by isolating the variable x.

10/x = 1/16

10 = x/16

10 * 16 = x

160 ounces = x

so 10 pounds is equivalent to 160 ounces. But we are not done yet.

We were asked to convert 10 pounds and 12 ounces.

So add together the ounces to find the total ounces:

160 ounces + 12 ounces = 172 ounces.

Answer:

Rn-222

Step-by-step explanation:

this decay takes specified step therefore Rn-222is not a decaying process

The nuclide that could not be involved in this decay series is U-239 (Option B).

A decay series for a nuclide is a sequence of radioactive decay that a particular radioactive isotope undergoes until it reaches a stable form. This sequence of decay is known as a decay chain or radioactive series.

The decay series from ²³⁸₉₂U to ²⁰⁶₈₂Pb involves a series of alpha and beta decays, producing a chain of daughter nuclides.

Each daughter nuclide in the chain is itself radioactive and decays into the next daughter nuclide until the stable nuclide ²⁰⁶₈₂Pb is reached.

A) Th-234: This nuclide is produced by the alpha decay of ²³⁸₉₂U and can decay into the next nuclide in the chain, Pa-234, by beta decay. Therefore, Th-234 can be involved in this decay series.

B) U-239: This nuclide is not produced by the alpha decay of ²³⁸₉₂U and cannot be involved in this decay series.

C) Po-218: This nuclide is produced by the alpha decay of ²²⁶₈₈Ra, which is a daughter nuclide in the decay series. Po-218 can decay into Pb-214, which is another daughter nuclide in the decay series. Therefore, Po-218 can be involved in this decay series.

D) Bi-214: This nuclide is produced by the beta decay of Po-214, which is a daughter nuclide in the decay series. Bi-214 can decay into Po-214 or Tl-210, which are both daughter nuclides in the decay series. Therefore, Bi-214 can be involved in this decay series.

E) Rn-222: This nuclide is produced by the alpha decay of ²²⁶₈₈Ra, which is a daughter nuclide in the decay series. Rn-222 can decay into Po-218, which is another daughter nuclide in the decay series. Therefore, Rn-222 can be involved in this decay series.

Therefore, U-239 is the required nuclide.

The degree required to factor a quadratic equation is 2, i.e degree 2.

An equation is said to be quadratic if and only if its degree is not greater than 2, and not lesser than two. So that any equation with degree 2 is a quadratic equation.

A degree of an expression is the highest power of the variable in it. For example, 5x + 2 is to one degree, 3x^2 + 2x - 1 is to degree 2, 10x^4 + 3x^3 - x^2 + 4x - 6 is to degree 4 etc.

The methods required in solving a given quadratic equation are either by factorization, completing the square, graph, or by algebraic formula.

Answer: The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours

Step-by-step explanation:

Unit rate is the ratio of the distance travelled o the time taken.

For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;

If distance = 9/8 miles and time = 5/6 hours

Hence the ratio that has a unit rate is 9/8 miles:5/6hours

If distance = 7 miles and time = 3/4 hours
