The figure shows a blueprint of a dining room, kitchen, and living room. Each square has a side length of 1/4 inch. Hardwood floors cost $11 per square foot. What is the cost of hardwood flooring for the dining room?
The cost of the hardwood flooring for the dining room is $
.
Step-by-step explanation:
Each square has a side length of 1/4 inch but you have said each square=1/4
Once you have found the amount of 1/4 inches you multiply the two numbers together, only then do you multiply it to $11 for the square area.

The angle of elevation of the top of a building from the foot of a tower is 70° and the angle of elevation of the top of the tower from the foot of the building is 40°. Find the height of the building if the tower is 50 m tall.
The height of the building located at a distance from the tower is approximately 163.716 meters.
How to determine the height of a building
After a careful reading to the statement, we represent all the information given in a geometric diagram. In this question we must apply trigonometric relationships to calculate the height of the building (h), in meters, based on the fact of the existing two right triangles. The diagram is presented in the image attached below.
Now we proceed to calculate the height of the building:
[tex]h = \left(\frac{50\,m}{\tan 40^{\circ}} \right)\cdot \tan 70^{\circ}[/tex]
h ≈ 163.716 m

If charged per cut, how much will it cost
to cut a log into eight pieces if cutting it
into four pieces costs $12?
Answer:
24
Step-by-step explanation:
4x=12
x=12/4
x=3
8×=?
8(3)=24
therefore, 8 pieces will cost 24.
another way is:
since 8 is 4×2
you could double the amount of money
12x2
which would also give you $24
If charged per cut, it will cost 24 dollar to cut a log into eight pieces if cutting it into four pieces costs $12
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that to cut a log into eight pieces if cutting it into four pieces costs $12.
Thus,
4x=12
x=12/4
x=3
Hence, for 8 pieces
8(3)=24
therefore, 8 pieces will cost 24.
If charged per cut, it will cost 24 dollar to cut a log into eight pieces if cutting it into four pieces costs $12

what is the median??
Answer:
median = 55.5
Step-by-step explanation:
Here we have 10 numbers which is an even number
then the median for the data set is the average of the two middle numbers
firstly ,we have to put the number of the set in order from least to greatest like this :
3 < 12 < 38 < 38 < 46 < 65 < 71 < 78 < 87 < 99
———————— ————————-
As you can see the middle two numbers are : 46 and 65

Three times a number increased by 9
is equal to twice the number decreased
by 4. Find the number
Let the number be "x"
According To Question[tex]3x + 9 = 2x - 4[/tex]
Solving It[tex]3x + 9= 2x - 4 \\ \\ \implies 3x - 2x = - 4 - 9 \\ \\ \implies x = - 13[/tex]
[tex] \therefore \text{the required number is = - 13}[/tex]
Hope this helpsAnswer:
- 35
Step-by-step explanation:
let the number be n then increased by 9 is n + 9 and decreased by 4 is n - 4 , so
3(n + 9) = 2(n - 4) ← distribute parenthesis on both sides
3n + 27 = 2n - 8 ( subtract 2n from both sides )
n + 27 = - 8 ( subtract 27 from both sides )
n = - 35
that is the number is - 35

What is the measure of \angle D∠Dangle, D?
Answer:
135⁰
Step-by-step explanation:
As in cyclic quadrilateral sum if opposite angles is equal to 180⁰
each row in the table below shows one possible set of angle measurements for this drawing
find the missing angle measurements
Applying the definitions of angles on a straight line and vertical angles, the missing angle measurementts are given in the table atached below.
What are Angles on a Straight Line?Angles found on a straight line equals 180 degrees.
What area Vertcial Angles?Vertical angles are congruent angles that lie directly opposite each other.
Second Row:
m∠LGK = 45° (given in the diagram)
m∠IGH = 35° (given in the table)
m∠KGJ = m∠IGH (vertical angles)
m∠KGJ = 35°
m∠JGI = 180 - m∠KGJ (angles on a straight line)
m∠JGI = 180 - 35 = 145°
m∠HGL = 180 - m∠LGK - m∠IGH (angles on a straight line)
m∠HGL = 180 - 45 - 35 = 100°
Third Row:
m∠LGK = 45° (given in the diagram)
m∠HGL = 97° (given in the table)
m∠KGJ = 180 - m∠HGL - m∠LGK (angles on a straight line)
m∠KGL= 180 - 97 - 45 = 38°
m∠JGI = 180 - m∠KGJ (angles on a straight line)
m∠JGI = 180 - 38 = 142°
m∠IGH = m∠KGL (vertical angles)
m∠IGH = 38°
Thus, applying the definitions of angles on a straight line and vertical angles, the missing angle measurementts are given in the table atached below.
