Answer:
49/12
Step-by-step explanation:
1 ⅓ can be written as 1 + 1/3
1 ⅓
= 1 + 1/3
LCM = 3
= 3/3 + 1/3
= ( 3 + 1 )/3
= 4/3
2 ¾
= 2 + 3/4
LCM = 4
= 8/4 + 3/4
= ( 8 + 3 )/4
= 11/4
1 ⅓ + 2 ¾
= 4/3 + 11/4
LCM = 3 x 4 = 12
4/3 x 4/4
= ( 4 x 4 )/( 3 x 4 )
= 16/12
11/4
= 11/4 x 3/3
= ( 11 x 3 )/( 4 x 3 )
= 33/12
16/12 + 33/12
= ( 16 + 33 )/12
= 49/12

A forest has 1260 trees.
The trees are maple, beech or oak.
A fifth of the trees are maple and the number of maple trees is 3 times the number of beech trees.
The rest of the trees are oak.
number of oak : number of beech = n : 1
Work out the value of n .
You must show how you get your answer.
Answers
Answer:
[tex]\huge\boxed{\sf n = 11}[/tex]
Step-by-step explanation:
Total trees = 1260 trees
Maple trees:
[tex]\displaystyle = \frac{1}{5} \ of \ total \ trees\\\\= \frac{1}{5} \times \ 1260\\\\= \frac{1260}{5} \\\\= 252 \ maple \ trees[/tex]
Beech trees:
Given that:
Maple trees = 3 × beech trees
=> There are 252 maple trees.
252 = 3 × beech trees
Divide 3 to both sides
252 / 3 = beech trees
84 trees = beech trees
[tex]\boxed{\sf beech \ trees = 84 \ trees\\}[/tex]
Oak trees:
It is said that all other trees are oak trees.
So, oak trees will be:
= total trees - maple trees - beech trees
= 1260 - 252 - 84
= 924 trees
The ratio of oak trees to beech trees:
= 924 : 84
Divide 84 to both sides
= 11 : 1
The question says:
number of oak : number of beech = n : 1
So, from the answer, it is clear that:
n = 11

What is the longest line segment that can be drawn in a right rectangular prism that is 15 cm long, 11 cm wide, and 10 cm tall?
Answers
Answer:
√446 ≈ 21.12 cm
Step-by-step explanation:
The longest dimension of a rectangular prism is the length of the space diagonal from one corner to the opposite corner through the center of the prism. The Pythagorean theorm tells you the square of its length is the sum of the squares of the dimensions of the prism:
d² = (15 cm)² +(11 cm)² +(10 cm)² = (225 +121 +100) cm² = 446 cm²
d = √446 cm ≈ 21.12 cm
The longest line segment that can be drawn in a right rectangular prism is about 21.12 cm.
_____
Additional comment
The square of the face diagonal is the sum of the squares of the dimensions of that face. The square of the space diagonal will be the sum of that square and the square of the remaining prism dimenaion, hence the sum of squares of all three prism dimensions.

The pencils at a store cost $0.65 each. Each pencil weighs 1.85 ounces. All the pencils at the store have a combined weight of 44.4 ounces. How much would it cost to buy all the pencils at the store?
Answers
Answer:
$15.60
Step-by-step explanation:
Hey there!
In order to solve this word problem, we need to find out how much pencils there are first
To do that, we need to take the total amount of pencil weight, which is 44.4 ounces, and divide that by the weight of one pencil, which is 1.85
44.4 divided by 1.85 is 24
So now we know that there are 24 pencils total in that store
What they are asking is how much does it cost to buy all the pencils in the store
It is already given that one pencil costs $0.65 and we found out that there are 24 pencils in total
So what we need to do is multiply 24 and 0.65 to find out the total cost of all the pencils in the store
24 times 0.65 is 15.60
So the cost to buy all the pencils at the store is $15.60

Answers
Answer: 312.3 square feet
Step-by-step explanation:
The area of Felipe’s bedroom floor is 312.3 square ft.
What is Pythagoras theorem:If we have a right-angled triangle then we can write the following equation,
(Hypotenuse)² = (Base)² + (Height)²
Properties of a rectangle:In the given figure attached below the properties are as follows:
ML = JKKL = JMarea = (Base × Width) = KL × MLIn the given question and in the figure attached below the given values are:
ML = 18 ft.KM = 25 ft.By applying Pythagoras theorem in ΔKML we get,
(KM)² = (KL)² + (ML)²
Putting all the values in the above equation,
(25)² = (KL)² + (18)²
By rearranging,
(KL)² = (25)² - (18)²
Applying the formula, a² - b² = (a + b)(a - b) we get,
(KL)² = (25 + 18)(25 - 18)
(KL)² = 43 × 7
KL = √301 ft.
Now the area is,
area = KL × ML
= (√301 × 18) square ft.
= 312.3 square ft.
Therefore, the area of Felipe’s bedroom floor is 312.3 square ft.

Do comment if you have any query.
Answer:
Slope: -1/3
Y-intercept: 2
Explanation:
The equation y = 2 - 1/3x is in slope-intercept form.
The format of slope intercept is y = mx + b, where m = slope and b = y-intercept.
The slope is the coefficient of x.
Hence, the slope of y = 2 - 1/3x is -1/3.
As for the y-intercept, that is the constant.
The constant in y = 2 - 1/3x is 2. Hence, the y-intercept is 2.

The line intercepts the y axis is b or 2 ( 0,2)
The slope is m = 2

Find the volume of the prism or compound shape.
Answers
The volume of the compound shape, that is the object formed by two hemispheres and a right cylinder is 66π in³.
How to determine the volume of the compound shape
The volume is the space occupied by an object. The volume of the compound shape equals the sum of the individual volumes, that is, of each part, which are represented by two hemispheres and a right cylinder.
Now we proceed to determine the volume of the compound shape (V), in cubic inches, by apply the following calculation:
V = (4/3) · π · (3 in)³ + π · (3 in)² · (10 in)
V = 66π in³

What is an equation of the the line that passes through the point (-1,4) and is parallel to the line x+y=4
This is so important!! Ive tried everything
Answers
Answer:
y = -x + 3
Step-by-step explanation:
the equation is parallel to the line
y + x = 4
y = 4 - x
parallel means the same slope. So our new equation has a slope of -1
Now, the equation of a line is given by y = mx + b where m is the slope.
y = -x + b
now we plug in the points given in the question to find b.
4 = 1 + b
b = 3
so the final answer is y = -x +3
make sure to comment if you need any further guidance.
x + y = 4
y = -x + 4
m = -1
Equation of the required line:
y= -1x + b
Now plug-in (-1,4) in the above equation
4 = -1 * (-1) + b
4 = 1 + b
4 -1 = b
b = 3
Equation:
y = -x + 3

A wall of a building is made from blocks that are each 1 cubic foot. The wall is 6 feet high and 6 feet wide. A window is made by removing some blocks as shown below. The window is 2 feet high by 2 feet wide. The wall is 6 feet high and 6 feet wide. The window is 2 feet high by 2 feet wide and is cut from the center of the wall. Suppose the wall is expanded to be 12 feet high by 12 feet wide, and the window is expanded to be 4 feet high by 4 feet wide. How will this change the volume of the wall? A. The volume will not change. B. The volume of the wall will double. C.
Answers
When the window is expanded to be 4 feet high by 4 feet wide, the volume of the wall quadruples or increases by factor of 4.
Volume of the wallThe volume of the wall is determined as follows;
V = h x w x t
where;
t is the thickness of the wallh is height of the wallw is width of the wallInitial volume of the wall when some blocks are removed to make a window is 2 feet high by 2 feet wide.
V1 = (6 - 2) x (6 - 2) x (t)
V1 = 16t ft³
Second volume of the wall when some blocks are removed to make a window is 4 feet high by 4 feet wide.
V2 = (12 - 4) x (12 - 4) x (t)
V2 = 64t ft³
V2 = 4(16t ft³)
V2 = 4(V1)
Thus, when the window is expanded to be 4 feet high by 4 feet wide, the volume of the wall quadruples or increases by factor of 4.
