Answer:
<B =121
Step-by-step explanation:
If the angles form a linear pair, they add to 180
6x-19 + 11x-22 = 180
Combine like terms
17x -41 = 180
Add 41 to each side
17x-41+41 = 180+41
17x = 221
Divide by 17
17x/17 =221/17
x =13
<b = 11x-22 = 11*13 -22 = 143-22 =121
How do you write an expression in factored form?
To write an expression in factored form, its products needs to be deduced.
What is an expression?
A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.
Factoring is the process of representing a given number or algebraic statement as the product of its components.
For example - Consider the binomial 3x^2-9x.
On simplifying it -
3x^2-9x = 3x(x-3)
So, here 3x^2-9x is the expanded form and 3·x·(x-3) is the factored form.
Another example is - Consider y^2-100.
The terms used here can all be expressed as squares.
y^2 − 100 = y^2 − 10^2
(y + 10)(y − 10)
The factors in this case are (y + 10) and (y - 10).
Therefore, the products are the factors of an expression.

Jackson is trying to find the density, in g/cm", of a block of wood.
The block of wood is in the shape of a cuboid.
He measures
the length as 13. 2 cm, correct to the nearest mm
the width as 16. 0 cm, correct to the nearest mm
the height as 21. 7 cm, correct to the nearest mm
He measures the mass as 1970 g, correct to the nearest 5 g.
By considering bounds, work out the density of the wood.
Give your answer to a suitable degree of accuracy.
You must show all your working and give a reason for your final answer.
The density of the wood is between 0.35 g/cm^3
The density of a substance can be calculated using the formula:
density = mass / volume
To calculate the volume of the cuboid, we can use the formula:
volume = length x width x height
So, using the measurements provided:
volume = 13.2 cm x 16.0 cm x 21.7 cm = 5541.44 cm^3
To calculate the density of the wood, we divide the mass by the volume:
density = 1970 g / 5541.44 cm^3
We can convert cm^3 to g/cm^3 by converting the volume to g
1cm^3 = 1g/cm^3
density = 1970 g / 5541.44 g/cm^3
density = 0.3555 g/cm^3
However, as the measurements provided have a degree of uncertainty, we should consider bounds to find the range of possible densities.
The lower bound for the length is 13.2 cm - 0.1 cm = 13.1 cm
The upper bound for the length is 13.2 cm + 0.1 cm = 13.3 cm
The lower bound for the width is 16.0 cm - 0.1 cm = 15.9 cm
The upper bound for the width is 16.0 cm + 0.1 cm = 16.1 cm
The lower bound for the height is 21.7 cm - 0.1 cm = 21.6 cm
The upper bound for the height is 21.7 cm + 0.1 cm = 21.8 cm
The lower bound for the mass is 1970 g - 5 g = 1965 g
The upper bound for the mass is 1970 g + 5 g = 1975 g
We can now use these bounds to calculate the range of possible densities:
Density lower bound = 1965 g / (13.3 cm x 16.1 cm x 21.8 cm) = 0.350 g/cm^3
Density upper bound = 1975 g / (13.1 cm x 15.9 cm x 21.6 cm) = 0.360 g/cm^3
So the density of the wood is between 0.35 and 0.36 g/cm^3 to one decimal place.
So the density is 0.35 g/cm^3 with an uncertainty of 0.01 g/cm^3

Santiago has 5 11/16 cups of dough to make dumpling. If he uses 13/16 cups of dough for each dumplings how many dumplings can santiago make?
Santiago can make 7 dumplings
To find out how many dumplings Santiago can make, we need to divide the total amount of dough (5 11/16 cups) by the amount of dough used per dumpling (13/16 cups).
To do this, we can first convert the fractions to have a common denominator. In this case, the denominator of 13/16 is 16, so we can convert 5 11/16 to have a denominator of 16 as well:
5 11/16 = (5 * 16) + 11/16 = 80 + 11/16
Now we can divide:
(80 + 11/16) ÷ (13/16) = (80 + 11) ÷ 13 = 91 ÷ 13
So Santiago can make 91/13 dumplings. This can be simplified further to 7 dumplings. So Santiago can make 7 dumplings with 5 11/16 cups of dough.

C=5/9(F−32)
The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?
A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 59 degree Celsius.
A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of 59 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only
D) I and II only
Answer:
C=5/9F−5/9(32)
you can see the slope of the graph is 5/9, which means that for an increase of 1 degree Fahrenheit, the increase is 5/9 of 1 degree Celsius. Therefore, statement I is true.
This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 9/5 degrees Fahrenheit. Since 95 = 1.8, statement II is true.
On the other hand, statement III is not true, since a temperature increase of 9/5 degrees Fahrenheit, not 5/9 degree Fahrenheit, is equal to a temperature increase of 1 degree Celsius.
The final answer is D.
Aiden bought 2 iPads for a total of $480. At this rate, what is the cost of 3 iPads?
Answer:
The cost of three would be $720.
Step-by-step explanation:
First you need to divide 480 by 2 which gives you 240. 240 is the cost of one iPad so 240 times 3 is 720.
Answer:
$720.Step-by-step explanation:
Karleebordelon6 has a wonderful answer, but I will provide a slightly different approach.
This can be solved by using proportions.
Take a look:
[tex]\frac{2 (ipads)}{480 (dollars)} =\frac{3 (ipads)}{x}[/tex]
After setting up the proportion, we can cross multiply.
[tex]480 * 3 = 1440\\[/tex]
[tex]2 *x = 2x[/tex]
Lastly, divide both products.
[tex]2x = 1440[/tex]
[tex]1440/2 = 720[/tex]
Therefore, the total cost of 3 iPads is $720.
In other words, x = 720.
[tex]\frac{2(ipads)}{480(dollars)} =\frac{3( ipads)}{720(dollars)}[/tex]

The value of angle x in the triangle shown is 78°
How to solve an equation?An equation is an expression that shows the relationship between two or more numbers.
A triangle is a polygon that has three sides and three angles. The sum of angles in a triangle is 180 degrees. Types of triangles are isosceles, scalene, equilateral
In the large triangle let the missing angle by y, hence:
y + 87 + 36 = 180 (sum of angle in a triangle)
y = 57°
In the triangle containing the angle 45, let the missing angle be z, hence:
z + y + 45 = 180 (angle in a triangle)
z + 57 + 45 = 180
z = 78°
x = z (corresponding angles are equal)
x = 78°
The value of x is 78°

Find the surface area and volume for this following pyramid
We calculated volume of pyramid = 160 cubic inches and surface area = 214.59 square inches.
what is pyramid?
A three-dimensional geometrical figure having flat polygon base along with a number of lateral triangular shaped faces.
How to calculate the volume and surface area of the pyramid?The given pyramid is a rectangular pyramid having length 10 inch and width 8 inch. The height of pyramid is 6 inches.
length, l = 10 inch
width, w = 8 inch
height, h = 6 inch
Now the volume will be, V = 1/3 × l × w ×h
V = 1/3 × 10 × 8× 6
hence, the volume = 160 cubic inches
We calculate the surface area of the given pyramid,
formula for surface area, SA = l × w + 1/2 × w ×√(4h²+l²) + 1/2 × l ×√(4h²+w²)
SA = 10 × 8 + 1/2 × 8 ×√(4×6²+10²) + 1/2 ×10×√(4×16²+8²)

Step-by-step explanation:
2x−6y=−2y−2 can be turned into x=2y−1.
Now you can substitute the equations.
−6x−4y=−2x−38
−6(2y−1)−4y=−2(2y−1)−38
Then you can simplify.
−12y+6=−36
−12y=−42
y=7/2

What is the 7th term of the geometric sequence where a1 = −4,096 and a4 = 64? (6 points)
Answer:
7th term is -1
Step-by-step explanation:
Mathematically, we have the nth term of a geometric sequence as:
Tn = ar^(n-1)
where a is the first term
n is the number of terms
T4 = ar^3
64 = -4096 * r^3
r^3 = -64/4096
r^3 = -1/64
r^3 = (-1/4)^3
r = -1/4
The 7th term is:
T7 = ar^6
T7 = -4,096 * (-1/4)^6
T7 = -1
The 7th term is -1
