Molly is making bags of trail mix for the hiking club. She will use 20 ounces of walnuts. 11.1 ounces of almonds, and 24.8 ounces of cashews. This amount makes 26 bags of trail mix. How many ounces are in each bag?

Answers

Answer:

2.15 ounces

Step-by-step explanation:

The total ounces of nuts in the bag is calculated as:

20 ounces of walnuts + 11.1 ounces of almonds + 24.8 ounces of cashews = 55.9 ounces.

From the question we are told that these amounts make 26 bags.

The number of ounces that are in each bag is calculated as:

26 bags = 55.9 ounces

1 bag = x ounces

Cross Multiply

26 bags × x ounces = 1 bag × 55.9 ounces

x ounces = 1 bag × 55.9 ounces/26 bags

x ounces = 2.15 ounces

Therefore, there are 1.94 ounces in each bag

rewrite the equation by completing the square x^2-2x+1=0

Answers

Answer:

(x-1)^2=0#

Explanation:

#x^2-2x+1=0#

Let's start by subtracting #1# from both sides so that the #x# terms are isolated:

#x^2-2x=-1#

Now, let's compute #(b/2)^2# and add it to both sides of the equation:

#(b/2)^2=(-2/2)^2=1#

#x^2-2x+1=-1+1#

Let's factorize the left hand side and simplify:

#(x-1)(x-1)=0#

#(x-1)^2=0#

Part B - What is the length of AM?

AM

Part C - What is the length of BM?

BM

Part D - Is point M the midpoint of AB? Justify your answer.

Answers

Answer:

Part A

x = 8

Part B

AM = 64 cm

Part C

BM = 64 cm

Part D

AB = AM + BM

Step-by-step explanation:

Consider the line segment below.

АM = (7x + 8) cm

BM = (9x – 8) cm

Part A - If AB is 128 centimeters long, what is the value of x?

AB = AM + BM

128 = (7x + 8) + (9x - 8)

128 = 7x + 9x + 8 - 8

128 = 16x

x = 128/16

x = 8

Part B - What is the length of AM?

АM = (7x + 8) cm

AM = 7(8) + 8 cm

AM = 56 + 8 cm

AM = 64 cm.

Part C - What is the length of BM?

BM = (9x – 8) cm

BM = 9 × 8 - 8 cm

BM = 72 - 8 cm

BM = 64 cm.

Part D - Is point M the midpoint of AB? Justify your answer.

A.............. M............... B

Hence: From the Above illustration,

M is the Midpoint because it divided AB into 2 equal parts

= AM and BM

Hence:

AB = AM + BM

Let's ignore the four corners for now.

Along the top, the length is 145 cm. Each tile is 25 mm, which is equivalent to 2.5 cm. So she'll need 145/2.5 = 58 tiles across the top

Similarly, she'll also need 58 tiles across the bottom as well because that length is also 145 cm.

Along the left side, she'll need 75/2.5 = 30 tiles and the right side is the same story.

So far we calculate 58+58+30+30 = 176 tiles

Add in the four corners to get 176+4 = 180 tiles total

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

A quicker method is to divide the perimeter (440 cm) over the side length of each tile (2.5 cm) and we get 440/2.5 = 176, which represents the number of tiles along the top, bottom, left and right sides. Again we're ignoring the corners. So we'll have to add them back in to get 176+4 = 180.

An open rectangular cistern when measured from outside is 1.35 metre long 1.08 metre board and 90 cm It is made up of iron which is 2.5 cm find the capacity of the question and the volume of the iron used.​

Answers

Answer:

The capacity of the cistern is [tex]1.2231~m^3[/tex]

The volume of iron used is [tex]0.0891~m^3[/tex]

Step-by-step explanation:

Volume

The volume of a rectangular box of dimensions x,y,z is given by:

V = x.y.z

The external dimensions of the rectangular cistern are 1.35 m, 1.08 m, and 0.90 m, thus the external volume is:

[tex]V_e=1.35*1.08*0.90=1.3122~m^3[/tex]

The cistern is made of iron 2.5 cm= 0.025 thick, thus the internal dimensions are:

1.35 - 0.025 = 1.325 m

1.08 - 0.025 = 1.055 m

0.90 - 0.025 = 0.875 m

The internal volume is:

[tex]V_i=1.325*1.055*0.875[/tex]

[tex]V_i=1.2231~m^3[/tex]

The capacity of the cistern is 1.2231~m^3

The volume of iron used is the difference between the external and the internal volumes:

[tex]V_{iron}=1.3122~m^3-1.2231~m^3[/tex]

[tex]V_{iron}=0.0891~m^3=89.1~lt[/tex]

The volume of iron used is [tex]0.0891~m^3[/tex]

Let BI = ST = x... (1)

By angle bisector property of a triangle, we have:

[tex] \frac{BI}{IS} = \frac{BT}{ST}.... (2)\\\\

Answers

Answer:

6 Dozen

Shortening: 6/4

Vanilla Extract: 2/2

Butter Flavoring: 2/4

Salt: 2/2

Baking Soda: 6/2

Cake Flour: 4

Food Coloring x 2

Step-by-step explanation:

6 ÷ 3 = 2

3 Dozen

Shortening: 3/4

Granulated Sugar: 9/4

Beaten Eggs: 1/4

Vanilla Extract:1/2

Butter Flavoring: 1/4

Salt: 1/2

Baking Soda: 3/2

Cake Flour: 2

Food Coloring

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

Shortening: 3/4 x 2

Granulated Sugar: 9/4 x 2

Beaten Eggs: 1/4 x 2

Vanilla Extract: 1/2 x 2

Butter Flavoring: 1/4 x 2

Salt: 1/2 x 2

Baking Soda: 3/2 x 2

Cake Flour: 2 x 2

Food Coloring x 2

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

6 Dozen

Shortening: 6/4

Granulated Sugar: 18/4

Beaten Eggs: 2/4

Vanilla Extract: 2/2

Butter Flavoring: 2/4

Salt: 2/2

Baking Soda: 6/2

Cake Flour: 4

Food Coloring x 2

6 Dozen cookies make with;

The amount of Shortening = 3/2

The amount of Salt = 2/2 = 1

The amount of Granulated Sugar = 9/2

The amount of Baking Soda = 6/2 = 3

The amount of Beaten Eggs = 1/2

The amount of Vanilla Extract = 1

The amount of Cake Flour = 4

The amount of Food Coloring = 1

The amount of Butter Flavoring = 1/2

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

For, 3 Dozen cookies we use;

The amount of Shortening = 3/4

The amount of Salt = 1/2

The amount of Granulated Sugar = 9/4

The amount of Beaten Eggs = 1/4

The amount of Vanilla Extract = 1/2

The amount of Butter Flavoring = 1/4

The amount of Baking Soda = 3/2

The amount of Cake Flour = 2

The amount of Food Coloring = 1/2

Since, We have to calculate all amount of things for 6 dozen cookies.

And, 3 x 2 = 6

Hence, 6 Dozen cookies make with;

The amount of Shortening = 3/4 x 2 = 3/2

The amount of Granulated Sugar = 9/4 x 2 = 9/2

The amount of Beaten Eggs = 1/4 x 2 = 1/2

The amount of Vanilla Extract = 1/2 x 2 = 1

The amount of Butter Flavoring = 1/4 x 2 = 1/2

The amount of Salt = 1/2 x 2 = 1

The amount of Baking Soda = 3/2 x 2 = 3

The amount of Cake Flour = 2 x 2 = 4

The amount of Food Coloring = 1/ 2 x 2 = 1

So, 6 Dozen cookies make with;

The amount of Shortening = 3/2

The amount of Salt = 2/2 = 1

The amount of Granulated Sugar = 9/2

The amount of Baking Soda = 6/2 = 3

The amount of Beaten Eggs = 1/2

The amount of Vanilla Extract = 1

The amount of Cake Flour = 4

The amount of Food Coloring = 1

The amount of Butter Flavoring = 1/2

How do I solve this radical and then check all the solutions?

Answers

Answer:

This problem of equations involving surds can be solved by :

Firstly,square both sides of the equation to do away with the surd

(√x+3)²=(x-3)²

Next,we do away with the surd or let me put it as sign of square root and FOIL out the RHS

x+3=x²-6x+9

Rearranging leads to:

x²-6x-x+9-3=0

x²-7x+6=0 which factorises to:

(x-6)(x-1)=0

Finding the zeros leads to

x=6 or 1

We now conduct a test to see which value(s) of x satisfy the equation

√6+3=6-3

√9=3

3=3, so x=6 is true

Now for 1,

√1+3=1-3

√4 is not equal to -2

Therefore we conclude that x=6

[tex]-\frac{3}{8}[/tex] + x = [tex]\frac{5}{16}[/tex]

x = [tex]\frac{5}{16}[/tex] - ( [tex]-\frac{3}{8}[/tex] ) = [tex]\frac{5}{16}[/tex] + [tex]\frac{3}{8}[/tex] = [tex]\frac{5 + 6}{16}[/tex] = [tex]\frac{11}{16}[/tex]

x = [tex]\frac{11}{16}[/tex]

-3/8=5/16

put x after -3/8 to find 5/16

-3/8+x=5/16

find x

move -3/8 to the other side

sign changes from -3/8 to 3/8

-3/8+3/8+x=5/16-3/8

x=5/16-3/8

find the common denominator which is 16

multiply by 2 for -3/8

(-3)(2)=-6
