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.

Find the volume of the prism or compound shape.
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

Step-by-step explanation:
tan=opposite
adjacent
Since you're trying to find the adjacent side to the angle 50, use tan.
So tan 50º= 6/x
Swap x and tan 50º , which puts tan 50º under the 6.
Use your calculator to find the approximate value of tan 50º (rounded to 4 decimals)

Answer:
Step-by-step explanation:
Let me see if I understand what you mean. Do you mean can you have 153 dollars in your pocket when all you have is 5 dollar bills?
If that is what you mean, then no that isn't possible. You can get 150 dollars or you can get 155 dollars, but you can't get 153.
In order to do the problem, using only 5 dollar bills, the number you choose must end in 0 or 5. If it ends in anything else, the task is impossible.

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.
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

The following system of equations can be used to determine the before-tax prices of dollars for each chicken

27c+ 17s = 809.50
46c + 34s = 1,495.00
What is the before-tax price of a chicken dinner?
1:11
Solving the system of equations, it is found that the before-tax price of a chicken dinner is of $15.5.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable c: Price of a chicken dinner.Variable s: Price of a steak dinner.The system is given by:
27c+ 17s = 809.50
46c + 34s = 1,495.00
Multiplying the second equation by -0.5 and adding with the first we can remove s, hence:
27c+ 17s = 809.50
-23c - 17s = -747.50.
4c = 62.
c = 62/4.
c = 15.5.
The before-tax price of a chicken dinner is of $15.5.
