Equation for Price Reduction:

Original Price * Percent Remaining of Original = New Price

Plug in the given values into the equation:

Original Price * 0.7 = $80

Divide both sides by 0.7 to isolate the Original Price:

80/0.7 =  $114

The 95% confidence range for the difference in the percentages of sleep deprived people in California and Oregon is from -0.0015 to 0.0175.

With a 95% confidence level or 0.05 significance level, we may say that this range overlaps 0 and that the proportions are not statistically different. In other words, based on the findings from this sample, the proportion of the CA and OR populations may be equal.

A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics. The 95% confidence level is the most popular, however other levels, such 90% or 99%, are occasionally used when computing confidence intervals. The percentage of related CIs over the long run that include the parameter's actual value is represented by the confidence level. For instance, 95% of all intervals calculated at the 95% level should include the parameter's actual value.

The equation representing total cost of the shirt is c = 1.06p.

As per the question, we are representing the total cost of the shirt as c and price of the shirt as p.

Calculating sales tax on the shirt -

Sales tax = p × 6%

Converting percentage to fraction and hence decimal form

Sales tax = p× 6/100

Sales tax = 0.06p

Forming the equation now -

Total cost = price of the shirt + sales tax on the shirt

c = p + 0.06p

Performing addition on Right Hand Side of the equation to find the equation representing total cost

c = 1.06p

Therefore, the equation representing the total cost of the shirt is c = 1.06p.

The smaller angle made by the hour hands of a clock at a given time is 137°30'. It is attained by using the concept of clocks on the problems.

What is a clock?

A clock is a device which is used for measuring and indicating the time. It has three hands, namely an hour hand, a minute hand and a second hand. A clock can be classified in two ways, one is a 12-hour clock and the other is a 24-hour clock.

Calculation of the smaller angle made by the hour hand  

For minute hand,

60 min makes an angle 360°

1 min = 6°

25 min = 6° × 25

= 150°

For hour hand,

12 hours makes an angle 360°

1 hour = 30°

1 min = 30° / 60

= 1/2°

25 min = 1/2° × 25

= 12°30'

The smaller angle made by hour hand is given by 150° - 12°30'

=137°30'

Hence, the smaller angle between the hour hands is 137°30'.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:  correct

Step-by-step explanation:

I'm assuming the "costs 72" is referring to 72 cents.

If so, then this is one way to solve:

(24 inches)/(72 cents) = (49 inches)/(x cents)

24/72 = 49/x

24*x = 72*49

x = 72*49/24

x = 147

It costs 147 cents, aka $1.47, to get 49 inches of wire.

To solve the equation, add 7 to both sides. The solution is a = 16.

A linear equation is an equation of which the highest degree of its variables is 1.

Steps to solve linear equations:

Recall that if  we subtract or add the same number to both sides of an equation, it does not change the equality.

The given problem:

Solve a-7=9

The variable is a. To isolate a, remove -7 by adding 7 to both sides:

a-7 +7 = 9 +7

a = 16 (solved)

The area of the rectangle is 576.

An area is the total amount of space enclosed by a shape or figures. In this case, the rectangle would be the shape or figure that is being defined and its area would be the total amount of space enclosed by it.

The length of the rectangle is 13 less than 2 and a half times its width means : L=2 [tex]\frac{1}{2}[/tex] w-13

Using the perimeter formula of the rectangle P= 2(L-W) we have

P=100

So

100=2(2( [tex]\frac{1}{2}[/tex])w-13+w)

Solve for W:

100= 2×[tex]\frac{5}{2}[/tex]w-26+2w

100=10/2w-26+2w

100=5w-26+2w

100=7w-26

100+26=7w

126=7w

126/7=w

W=18

We can find the length L=2 [tex]\frac{1}{2}[/tex]w-13 = [tex]\frac{5}{2}[/tex](18) -13

=45-13

L= 32

Area of the rectangle is A= L×W= 32×18=576

Hence, the area of rectangle is 576.

Using the distance formula, the approximate distance between the points (1, -2) and (-9, 3) is: 11 units.

To find the distance of two points on a coordinate grid, the distance formula that is employed is: d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given the points are on a coordinate grid:

(1, -2) = (x1, y1)

(-9, 3) = (x2, y2)

Plug in the  values into the distance formula:

d = √[(−9−1)² + (3−(−2))²]

d = √[(−10)² + (5)²]

d = √(100 + 25)

d = √125

d = 11.18034

d ≈ 11 units.

Therefore, using the distance formula, the approximate distance between the points (1, -2) and (-9, 3) is: 11 units.

The coordinates of the midpoint is M(x, y) = (17, 27) and its length is 6√34 units.

In this problem we have the coordinates of two endpoints of a line segment, of which we must find the location of its midpoint by using the midpoint formula, whose vector form shall be used. Later, we determine the length of the line segment by calculating the vector behind the line segment and its magnitude.

If we know that P(x, y) = (26, 12) and Q(x, y) = (8, 42), then the location of its midpoint and its length are, respectively:

Midpoint

M(x, y) = 0.5 · P(x, y) + 0.5 · Q(x, y)

M(x, y) = 0.5 · (26, 12) + 0.5 · (8, 42)

M(x, y) = (13, 6) + (4, 21)

M(x, y) = (17, 27)

Length

PQ = (8, 42) - (26, 12)

PQ = (- 18, 30)

PQ = √[(- 18)² + 30²]

PQ = 6√34

Answer:

p = 12

Step-by-step explanation:

Angles in a straight line sum to 180 degrees. Given the two algebraic angles, this can be expressed as follows:

(6p + 3) + (9p - 3) = 180

Take out the brackets:

6p + 3 + 9p - 3 = 180

Combine the like terms:

15p = 180

Divide both sides by 15:

p = 180/15

Simplify:

p = 12

If you want to verify the answer is correct, substitute it back into the original equation:

(6(12) + 3) + (9(12) - 3) = 180

Write the phrase as an expression the quotient of 22 and a number [tex]a[/tex].The quotient of 22 and  [tex]a[/tex]  number = 22/[tex]a[/tex]

Given that

number = 22

quotient =   [tex]a[/tex]

To find

The mathematical equation or relation between quotient of 22 and a number [tex]a[/tex].

So according the question

We have

quotient = 22

divisor =   [tex]a[/tex]

For finding the relation between given quotient and divisor, let's firstly know about Dividend, Divisor, Quotient and Remainder,

In Mathematics, the dividend is the value that is divided by another value to get the result. The dividend is the base of any division method.

An integer that divides another integer to obtain a result is called a divisor. The result of this division, or quotient, is the dividend, which is the original number that was divided.

Quotient = Dividend ÷ Divisor

When we divide one number by another, the result is a quotient. As an illustration, when we divide 6 by 3, we obtain the answer 2, which is the quotient. A decimal or an integer can both be used as the quotient. When dividing exactly, as when 10 ÷5 = 2, the quotient is an integer, whereas when dividing roughly, as when 12÷ 5 = 2.4, the quotient is a decimal. Although a quotient can be greater than the divisor, it will never be greater than the dividend.

The value remaining after division is known as the Remainder. After division, we are left with a value if a number (dividend) cannot be divided entirely by another number (divisor). This value is called the remainder.

Now, from question  

We have a quotient of 22 that is [tex]a[/tex].

So, 22 fully divided by [tex]a[/tex].

In mathematical form,

                        = 22/[tex]a[/tex]

The quotient of 22 and [tex]a[/tex]  number = 22/[tex]a[/tex]

Therefore,

∠RIM = 90°

Line AM, ZG and RI intersect at point I.

Therefore,

3x - 56 = x + 2 (vertically opposite angles)

3x - x = 2 + 56

2x = 58

x = 58 / 2

x = 29

4z + 7 + x + 2 = 90

4z + 7 + 29 + 2 = 90

4z = 90 - 7 - 2 - 29

4z = 52

z = 52 / 4

z = 13

∠RIG = 4z + 7

∠RIG = 4(13) + 7

∠RIG = 52 + 7

∠RIG = 59°
