Answer:

yn +y -xn

Step-by-step explanation:

Mean= sum of numbers ÷number of numbers

x= sum of n numbers ÷n

Multiply both sides by n:

xn= sum of n numbers

sum of n numbers= xn -----(1)

Let the number added be a.

After a has been added,

y= (sum of n numbers +a) ÷(n+1)

Multiply both sides by (n +1):

y(n +1)= sum of n numbers +a

sum of n numbers= y(n +1) -a -----(2)

Substitute (1) into (2):

xn= y(n +1) -a

Expand:

xn= yn +y -a

a= yn +y -xn

Let's check!

Let the numbers be 1, 2, 3 and 4.

mean, x= 10 ÷4= 2.5

n= 4

Let the new number added, a, be 7.

a= 7

mean, y= 17 ÷5= 3.4

a= yn +y -xn

a= 3.4(4) +3.4 -2.5(4)

a= 7

Thus, the expression is true.

Answer:

axb/2

Step-by-step explanation:

When theres a triangle with a right angle you need to make in a rectangle and divide it by 2

Answer:

In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.

Step-by-step explanation:

The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.

Answer:

John's rectangle is 4 units long

John's rectangle is [tex]3\frac{1}{2}[/tex] units long

The area of John's rectangle is 14 units^2

Step-by-step explanation:

A rectangle has four sides that comprise of two pairs of equal length sides

The side which is the longest side of a rectangle is known as the length, L, of the rectangle

The side which is the shortest side of a rectangle is known as the width, W of the rectangle

Based on the given measurement, the length of the given rectangle which is the length of longest side of the rectangle, which is the 4 units length side

Therefore;

∴ John's Rectangle is L = 4 units long

the width of the given rectangle which is the length of shortest side of the rectangle, which is the side with lengths 3 units and 1/2 units length side

∴ The length of the shortest side of the rectangle, W = 3 units + 1/2 units = 3 1/2 units

∴ John's rectangle is W = [tex]3\frac{1}{2}[/tex] units wide

The area of John's rectangle, A = L × W

∴ The area of John's rectangle, A = 4 units × [tex]3\frac{1}{2}[/tex] units = 14 units².

Answer:

It's C.

Step-by-step explanation:

The area of a triangle is base times height times 1/2. The base times the height of that triangle is 66. 66 times 1/2 is 33. So, the correct answer is C.

Answer:

66 cm

(B) An uncontrolled experiment.

Step-by-step explanation:

In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled

Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the  cholesterol level is decreased after particular time period,

Hence, it is an uncontrolled experiment.

Thus, option B is correct.

1/3 (3/2 x -3) = -5/6x

Answer: x=3/4

Hope This Helps!

Answer:

x=3/4

Step-by-step explanation:

1/3 times 3/2 x is 1/2x

1/3 times -3 is -1

1/2x-1=-5/6x

1/2 is equal to 3/6

-1=-5/6x-3/6x

-1=-8/6x

x=6/8

Answer:

4 y + 3

Step-by-step explanation:

y = -3/4

Step-by-step explanation:

We can use a ratio to solve

247 dollars       171 dollars

---------------- = -------------

13 hours             x hours

Using cross products

247* x = 13*171

247x =2223

Divide each side by 247

247x/247 =2223/247

Step-by-step explanation:

Here is the complete question

Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?

Volume of a cone = [tex]\frac{1}{3}[/tex]πr²h

π = 22/7

Radius = diameter / 2 = 6 /2 = 3 inches

(1/3) x (3^2) x (22/7) x 5  = 47.14 in³

hope this helps!!!!

Answer:

A) X = 8

B) X = 4.3 or 13/3

Step-by-step explanation:

A) 5x - 10 = 30

(add ten to both sides)

    5x = 40

(divide by 5 on both sides)

    x = 8

B) 3x + 8 = 21

(subtract 8 to both sides)

    3x = 13

(divide by 3 on both sides)

    x = 4.3 or 13/3
