Answers
Answer:
29.86 units
Step-by-step explanation:
In the triangle BIS, IT is the bisector of angle BIS,
[tex] BI \cong ST.... (given) \\[/tex]
Let BI = ST = x... (1)
By angle bisector property of a triangle, we have:
[tex] \frac{BI}{IS} = \frac{BT}{ST}.... (2)\\\\
\frac{x}{12} = \frac{4}{x}\\\\
x\times x = 12\times 4\\\\
x^2 = 48\\\\
x=\sqrt{48}\\\\
x = 6.92820323\\\\
x = 6.93\\[/tex]
Therefore,
BI = ST =6.93
Perimeter of triangle BIS
= BI + IS + ST + BT
= 6.93 + 12 + 6.93 + 4
= 29.86 units

How make 6 dozens cookies
Answers
Answer:
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
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

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#

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]
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

Answer:

Step-by-step explanation:
4(x-1)/8 = 2(x+2)/7
7*4(x-1) = 8*2(x+2)
28(x-1) = 16(x+2)
28*x + 28*-1 = 16*x + 16*2
28x - 28 = 16x + 32
28x - 16x = 32 + 28
12x = 60
x = 60/12
x = 5
Check:
4(5-1)/8 = 2(5+2)/7
4*4/8 = 2*7/7
16/8 = 2*1 = 2

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
