Find the area of the shaded region of circle F below. Round your answer to the
nearest tenth if necessary.
Check the picture below, so the shaded area is really just the area of one quarter of a circle's area with a radius of 7, and a triangle whose base is 7 and height is 7, so let's simply sum both of them up.
[tex]\stackrel{\textit{\Large Areas}}{\stackrel{\textit{quarter of a circle}}{\cfrac{1}{4}(\pi)(7)^2}~~ + ~~\stackrel{triangle}{\cfrac{1}{2}(7)(7)}}\implies \cfrac{49\pi }{4}~~ + ~~\cfrac{49}{2}~~ \approx~~63.0[/tex]
Help meeeeeeeeeeeee question 1 !!!!
Answer:
7 times $8 = 56
Step-by-step explanation:
Question 1:
So, we are going to multiply 7 by $8.
If Brandie earns 8 dollars an hour, then we can multiply 8 by 7 to find out how much money Brandie earns in 7 hours.
Now multiply 8 by 7.
8 * 7 = 56
The independent variable is the hours. The hours can change, but this affects what the dependent result is.
The amount of money stays the same.
The dependent variable is the result, which is the total amount of money earned.

15. Find the value of x.
(68 - x)
3x
Answer:
17=x
Step-by-step explanation:
In this case, we need to use Vertical Angles Theorem to solve this problem. Basically, because of the position of the angles, they are congruent.
68-x = 3x
Add x to both sides
68=4x
Divide by 4
17=x
Hope this helps!
Answer:
The value of 'x' is: 17°
Step-by-step explanation:
From what is being shown, there are two angles that are given:
(68 - x)°
3x°
Since they are congruent angles, meaning they are equal to each other, they will be put into a(n) equation such like shown below:
(68 - x)° = 3x°
(Then remove the parenthesis)
68° - x° = 3x°
+ x°=+3x°
------------------
68° = 4x°
------------------
(Divide both sides by 4)
[tex]\frac{68}{4} = \frac{4x}{4}[/tex]
------------------
17° = x
------------------
Your value of 'x' is 17.

The equations below were created by students who were asked to write equivalent expressions on either side of the equals sign. Imagine you are a teacher. Your job is to decide whether their work is right or wrong. If you see an equation that is false, then: Say it is False. Then how you know it is false. 2(n + 3) = 2n + 3 *
Answer/Step-by-step explanation:
Given that a student wrote the following equation:
[tex] 2(n + 3) = 2n + 3 [/tex]
Looking at the expression on both sides, they don't seem equal. To be sure, use any value to represent "n" in the equation. Then, simply. If what you have on your left is equal to what you have in your right, then the equation is TRUE. If otherwise, it is FALSE.
Let n = 2
[tex] 2(n + 3) = 2n + 3 [/tex]
[tex] 2n + 6 = 2n + 3 [/tex]
Plug in the value of n
[tex] 2(2) + 6 = 2(2) + 3 [/tex]
[tex] 4 + 6 = 4 + 3 [/tex]
[tex] 10 = 7 [/tex]
This is not FALSE. 10 ≠ 7.
Therefore, the equation written by the student is FALSE.

5. The measure of the second angle of a triangle is 20 more than the measure of the first, and the measure of the third angle is 10 less than three times the first. What is the measure of each of the three angles of a triangle?
So first we have to find equation form angles.
Let :-first angle of triangle be xPart one :-Statement :- The measure of the second angle of a triangle is 20 more than the measure of the first.
Equation :-
second angle = 20 + x
{ Remember people get's confused when to multiply and when to add. when ever there "more than" then we will add and when there is ,"times" we will multiply}
Part 2 :-Statement :-
the third angle is 10 less than three times the first
Now just see first less means we have to subtract 10 from 3 times the first means 3 × first angle.
Equation :-
third angle = 3x - 10
Part 3 :-Now let's represent :-
First angle be ∠1Second angle be ∠2third angle be ∠3We know sum of angles of triangle is equal to 180°
So :-
∠ 1 + ∠ 2 + ∠ 3 = 180°x + 3x - 10 + 20 + x = 180°4x - 10 + 20 + x = 180°5x - 10 + 20 = 180°5x + 10 = 180°5x = 180° - 10°5x = 170x = 170/5x = 34°Measure of angles :-
∠1 = x∠ 1 = 34°∠2 = 20 + x∠2 = 20 + 34°∠2 = 54°∠3 = 3x - 10∠3 = 3 × 34 - 10∠3 = 102 - 10∠3 = 92°[tex]\bold{\huge{\underline{ Solution }}}[/tex]
Given :-We have given in the question that, The measure of second angle is 20 more than the measure of first angle The measure of third angle is 10 less than three times the first. To Find :- We have to find the measure of all the three angles of triangle. Let's Begin :-Let the first angle be x
According to the question,
Second angle = x + 20[ 2nd angle is 20 more than the first angle ]
Third angle = 3x - 10[ 3rd angle is 10 less than thrice times the first angle ]
By using Angle sum property
It states that the sum of the angles of triangles are equal to 180°That is,
[tex]\sf{ x + ( x + 20) + ( 3x - 10) = 180{\degree}}[/tex]
[tex]\sf{ x + x + 20 + 3x - 10 = 180{\degree}}[/tex]
[tex]\sf{ 5x + 10 = 180{\degree}}[/tex]
[tex]\sf{ 5x = 180 - 10}[/tex]
[tex]\sf{ 5x = 170}[/tex]
[tex]\sf{ x = }{\sf{\dfrac{ 170}{5}}}[/tex]
[tex]\sf{ x = }{\sf{\cancel{\dfrac{ 170}{5}}}}[/tex]
[tex]\bold{ x = 34{\degree}}[/tex]
Thus,
The first angle is 34°The second angle [tex]\sf{ = 34 + 20}[/tex][tex]\bold{ = 54{\degree}}[/tex]The third angle [tex]\sf{ = 3(34 ) - 10}[/tex][tex]\sf{ = 102 - 10}[/tex][tex]\bold{ = 92 {\degree}}[/tex]Hence, The three angles of the given triangle are 34° , 54° and 92°
[tex]\bold{\huge{\underline{ Verification }}}[/tex]
Here, we have
The first angle = 34°The second angle = 54°The third angle = 92°By using Angle sum property :-
[tex]\sf{ 34 + 54 + 92 = 180{\degree}}[/tex]
[tex]\sf{ 88 + 92 = 180{\degree}}[/tex]
[tex]\sf{ 180 = 180{\degree}}[/tex]
[tex]\bold{ LHS = RHS }[/tex]
Hence, Verified

A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 9 hours? What is the rate of speed of the jet?
Answer:
235 miles per hour and 2,115 miles in 9 hours
Step-by-step explanation:
First determine how many miles the jet files in one hour:
470/2 =235 miles/hour
We want to know how many hours the jet could fly in 9 hours, so we multiply this value by 9.
235 x 9 = 2115 miles
Therefore, the jet could fly 2115 miles in 9 hours.

A floor whose length and width is 50 m and 40 m respectively needs to be covered by rectangular tiles. The dimension of each tile is 1 m x 2 m. Find the total number of tiles that would be required to fully cover the floor.
Answer:
1000 tiles required.
explanation:
area of rectangle = Length * Width
Tiles dimension:
length: 1 meterwidth: 2 meterFloor dimension:
length: 50 meterwidth: 40 meterArea of floor:
Length * Width
50 * 40
2000 m²
Area of each tile:
Length * Width
1 * 2
2 m²
Number of tiles required = Area of floor ÷ Area of each tile
→ tiles = 2000/2
→ tiles = 1000
See below.
1000
area of rectangle = width x length
Given: width of floor = 40 m length of floor = 50 m ⇒ area of floor = 40 x 50 = 2000 m²
width of tile = 1 m length of tile = 2 m ⇒ area of tile = 1 x 2 = 2 m² Number of tiles needed = area of floor ÷ area of one tile = 2000 ÷ 2 = 1000
