Answer:

a) = 1007

b) =403.75

Step-by-step explanation:

Selling price is the amount at which an article or product is sold. It is represented by SP. The formula of S.P. can be given in terms of Profit or Loss as- 1. If S.P. is greater than C.P. which is the cost price of the item then a profit is gained by the shopkeeper.

a)

[tex]cp = 950 \: gain \: = 6\% \\ 950 \times \frac{6}{100} \\ \frac{950}{1} \times \frac{6}{100} \\ \frac{5,700}{100} \\ = 57 \\ add \: 57 \: to \: the \: original \: price \\ = 950 + 57 \\ = 1,007[/tex]

b)

[tex]cp \: = 380 \: gain \: = 6 \frac{1}{4} \\ cp = 380 \: gain \: = 6.25 \\ 380 \times \frac{6.25}{100} \\ \frac{380}{1} \times \frac{6.25}{100} \\ \frac{2,375}{100} \\ = 23.75 \\ add \: 23.75 \: to \: 380 \\ = 23.75 + 380 \\ = 403.75[/tex]

Step-by-step explanation:

The area of the shaded portion is (16π - 32) in².

The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter.

In the picture attached, the circle is shown.

The area of one-quarter of the circle is given by;

[tex]\rm = \dfrac{1}{4}\times Area\ of \ a \ circle \\\\= \dfrac{1}{4}\times \pi \times radius^2\\\\ = \dfrac{1}{4}\times \pi \times 8^2\\\\= 16\pi \ in^2[/tex]

The area of the triangle is given by;

[tex]\rm = \dfrac{1}{2} \times base\times height \\\\= \dfrac{1}{2} \times 8\times 8 = 32 \ in^2[/tex]

The area of the shaded portion is;

Shaded area = Area of one-quarter of the circle - Area of the triangle = (16π - 32) in²

Hence, the area of the shaded portion is (16π - 32) in².

The error made by the Gabriel in calculating the change amount, is that he subtract the $2 instead of adding $2.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

The expression used by the Gabriel to represent his total cost  is,

[tex]2.5x+2y - 2[/tex]

As, Gabriel has to receive the change amount of $30. Thus, he has to subtract this amount from the total cost. This statement can be present as,

[tex]\rm Change=30-(2.5x+2y - 2)\\\rm Change=30-2.5x-2y + 2\\\rm Change=32-2.5x-2y[/tex]

Now, the expression used by him to represent the amount of change he should receive from $30 is,

[tex]28 -2.5x - 2y[/tex]

Hence, the error made by the Gabriel in calculating the change amount, is that he subtract the $2 instead of adding $2.

Answer:

[tex]\frac{4}{33}[/tex] and [tex]\frac{1}{27}[/tex]

Step-by-step explanation:

We require 2 equations with the repeating numbers placed after the decimal point.

let x = 0.1212...... (1) ← multiply both sides by 10

100x = 12.1212.... (2)

subtract (1) from (2) thus eliminating the repeating numbers

99x = 12 ( divide both sides by 99 )

x = [tex]\frac{12}{99}[/tex] = [tex]\frac{4}{33}[/tex] ← in simplest form

-------------------------------------------------------

let x = 0.037037....... (1) ← multiply both sides by 1000

1000x = 37.037037..... (2)

subtract (1) from (2) to eliminate the repeating numbers

999x = 37 ( divide both sides by 999 )

x = [tex]\frac{37}{999}[/tex] = [tex]\frac{1}{27}[/tex] ← in simplest form

A regular polygon with exterior angle of 7.2 degrees is a 50-gon.

Regular polygon are polygon that are equiangular. This simply means they are polygon with equal angles.

The formula to find the number of sides of a polygon using exterior angle is as follows:

where

n = number of sides

Therefore,

7.2 = 360 / n

cross multiply

7.2n = 360

divide both sides by 7.2

n = 360 / 7.2

n = 50

The polygon has 50 sides. Therefore, it is a 50-gon

Answer:

Decrease by half.

Step-by-step explanation:

Let's say the length, width, and height is x,y,z respectively.

V = xyz

Now, when z is decreased by half, we get xyz : 2 which can either be written as (xyz) : 2 or xy(z:2)

So in short, if the height decrease by half, the volume will decrease in half.

If she spends $42 a week on coffee and every day she spends the same amount (I don't see this in the question, only doughnuts.), then $30 can get her 30 : 42 = 5/7 of a week of coffee -> 5 days.

So, she spends 5 days on coffee -> she must also spend 5 days on doughnuts

And since she spends 30 dollars equally everyday, she spends 30 : 5 = $6 everyday on doughnuts

Answer:

Total number of CDs= 10+5+12+3=30

Number of jazz CD= 3

Total number of outcomes that Kyle will select a jazz CD from the box= 3C1= 3!/1!2!= 3

Total number of outcomes for any CD = 30C1 = 30!/1$29! =30

Hence, the probability of picking jazz CD =3/30 = 1/10 0.1

Now since, one CD is out, the total number of CD left = 29

No. of country CD= 10

Total number of outcomes that Kyle will select a country CD from the box= 10C1= 10!/1!9!= 10

Total number of outcomes for any CD(one is out) = 29C1 = 29!/1$28! =29

Hence, the probability of picking country CD =10/29 = 0.344827

The square root of 20 is between 4 and 5.

They are the numbers represented by positive real numbers where the fractions and decimal numbers are not included.

For solving this question, you should list the whole numbers whose your square is less than 30. Your list must present the following numbers:

0 ⇒ 0²=0

1 ⇒ 1²=1

2 ⇒ 2²=4

3 ⇒3²=9

4 ⇒ 4²=16

5 ⇒ 5²=25

Note that 6²=36, it is greater than 30,because of this it is not in the previous list.

The question asks to determine between which two whole numbers lies the square root of 20. Therefore, from the previous list, it is possible to see that the value 20 is between 16 and 25. The square root of 16 and 25 is equal to 4 and 5, respectively.

Thus, the square root of 20 is between 4 and 5. You can check this results in your calculator:[tex]\sqrt{20}=2\sqrt{5}=4.47[/tex]

115+x=180

-115

x=65

the other angle is 65

Hope This Helps!!!

65°

Step-by-step explanation:

let the third angle be x

so, sum of all angles of a triangle = 180°

x° + 75° + 40° = 180°

x + 115° = 180°

x = 180° - 115°
