If the percent of discount of an item is 25 percent and the sale price is $40 what is the original price

Answer:

y intercept is (0,7) & x is (7/4,0)

Step-by-step explanation:

you put 0 for y or x and solve to get the intercept. for y int, you put 0 where the x is. for x int, put 0 at y.

y intercept is (0,7).

y = 4(0) + 7

y = 0 + 7

y = 7

x intercept is (7/4,0)

0 = 4x + 7

7 = 4x

7/4 = 4x/4

7/4 = x

Answer:

It is a rational number.

Step-by-step explanation:

since it is not a perfect square therefore it does not have an exact square root. also any number that is positive or negative, positive or zero, and can be write as a fraction

θ is in quadrant I, so cos(θ) and sin(θ) and hence tan(θ) are all positive.

Recall that

sec²(θ) = 1 + tan²(θ)

We have

cos(θ) = 2/√14   ⇒   sec(θ) = √14/2 = √(7/2)

Then

tan(θ) = +√(sec²(θ) - 1) = √(5/2)

Also recall the identities

sin(x + y) = sin(x) cos(y) + cos(x) sin(y)

cos(x + y) = cos(x) cos(y) - sin(x) sin(y)

from which we get

tan(x + y) = (sin(x) cos(y) + cos(x) sin(y)) / (cos(x) cos(y) - sin(x) sin(y))

tan(x + y) = (tan(x) + tan(y)) / (1 - tan(x) tan(y))

so that

tan(2θ) = 2 tan(θ) / (1 - tan²(θ)) = -(2√10)/3

Step-by-step explanation:

Answer:

[tex]\huge\boxed{\sf r = 10.5}[/tex]

Step-by-step explanation:

Since it is a right-angled triangle, it has base, perpendicular and hypotenuse.

Base = r

Perpendicular = 14

Hypotenuse = r + 7

Using Pythagoras theorem:

[tex](Hypotenuse)^2 = (Base)^2+(Perp)^2[/tex]

Put the values

(r + 7)² = (r)² + (14)²

Using formula a² + 2ab + b² = (a + b)²

r² + 14r + 49 = r² + 196

Subtract r² to both sides

14r + 49 = 196

Subtract 49 to both sides

14r = 196 - 49

14r = 147

Divide 14 to both sides

r = 147 / 14

r = 10.5

Answer:

95

Step-by-step explanation:

21.25 times 4 is 85

so it's 3 point something

then you do 80.75 divided by 21.25 and get 3.8 and then 25 times 3.8 is 95

Links are in a chain that is 80.75 inches long are 95.

The number of links on a chain is proportional to the length of the chain.

If 25 links create a chain that is 21.25 inches long,

then how many links are in a chain that is 80.75 inches long.

The inch can be defined as a unit of length in the customary system of measurement.

21.25 times 4 is 85.

Then you divided 80.75 by 21.25.

[tex]\frac{80.75}{21.25} =3.8[/tex]

Then 25 times 3.8 is 95

[tex]3.8\times 25=95[/tex]

Answer: B. √25 + 1.75.

Step-by-step explanation: Rational Numbers are numbers that terminate or don't need to be terminated.  For example, 1/3 is a repeating number, but we can terminate the value, whereas pi is never ending, and there is no terminating with that value.  Numbers like 5.56 and 7/8 are rational because they don't need to be terminated to be rational.  √25 is 5, no decimals to terminate or anything, and that makes the value rational.  1.75 is also rational, and that's why equation c is fully rational.  √3 and √2 can't terminate, because both are 1.73205080757 and 1.41421356237, which means that they still can't terminate.  Pi cannot terminate, so that's why the answer choices with pi aren't rational.

They are exempt from income tax and we would get the income tax withheld as $340

Income tax is a tax applied on individuals or entities concerning income or profit earned by them.

You earn $1,166 gross taxable income every week and have claimed no exemptions. assuming that you have no other sources of income.

Gross taxable Income = $ 1,166

Rate of Income tax = 30%

Amount of income tax = 30 % of 1,166

 = 30/100 × 1,166

= $339.6

= $340

Therefore. they are exempt from income tax and we would get the income tax withheld as $340.

Step-by-step explanation:

The missing line is slopes of both lines are equivalent to (z - v) / (x - w)

The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

Given is proof of line PQ is parallel to the line P'Q',

So,

Slope = change in y / change in x

Slope of PQ = (z - v) / (x - w)

Slope of P'Q' = (z + b - (v + b)) / ((x + a) - (w + a))

Slope of P'Q' = (z - v) / (x - w)

The slopes of both lines are equivalent to (z - v) / (x - w)

Hence, the missing line is slopes of both lines are equivalent to (z - v) / (x - w)

Answer:

A sampling distribution is a statistic that is arrived out through repeated sampling from a larger population.

It describes a range of possible outcomes that of a statistic, such as the mean or mode of some variable, as it truly exists a population.

The majority of data analyzed by researchers are actually drawn from samples, and not populations.

Step-by-step explanation:

In statistics, a sampling distribution or finite-sample distribution is the probability distribution of a given random-sample-based statistic. If an arbitrarily large number of samples, each involving multiple observations (data points), were separately used in order to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample, then the sampling distribution is the probability distribution of the values that the statistic takes on. In many contexts, only one sample is observed, but the sampling distribution can be found theoretically.
