find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Answers
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over. How many litres of lemonade were sold?
Answers
Given :
For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.
To Find :
How many litres of lemonade were sold.
Solution :
Initial amount of lemonade, I = 12 1/2 = 25/2 litres.
Final amount of lemonade, F = 2 5/8 = 21/8 litres.
Amount of lemonade sold, A = I - F
A = 25/2 - 21/8 litres
A = 9.875 litres
Therefore, 9.875 litres of lemonade were sold.
Hence, this is the required solution.
QUICK WHAT IS0.034 is 110 of 0.0034.
Answers
Step-by-step explanation:
. We assume, that the number 10 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 10 is 100%, so we can write it down as 10=100%.
4. We know, that x is 0.034% of the output value, so we can write it down as x=0.034%.
5. Now we have two simple equations:
1) 10=100%
2) x=0.034%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
10/x=100%/0.034%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 0.034% of 10
10/x=100/0.034
(10/x)*x=(100/0.034)*x - we multiply both sides of the equation by x
10=2941.1764705882*x - we divide both sides of the equation by (2941.1764705882) to get x
10/2941.1764705882=x
0.0034=x
x=0.0034
now we have:
0.034% of 10=0.0034

if triangle ABC are congruent, what is the length of line segment AB?
Answers
Assuming you meant to say triangle ABC is congruent to triangle DEF, then the corresponding pieces AB and DE are the same length.
In short AB = DE.
Since DE = 10, this makes AB = 10 also.

E. 11b+187−2,756÷13
Answers
Answer:
A, and D
Step-by-step explanation:
If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.
The expression that has a value of 180 when b = 4 is D. 51b−24
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
87b - 179 + 957/87.
= 87(4) - 179 + 857/87.
= 348 - 179 + 9.85, will not be 180.
33b12, will not be 180 at b = 4.
b² + 120, will not be 180 at b = 4.
51b - 24.
= 51(4) - 24.
= 204 - 24.
= 180.
11b + 187 - 1756/13.
= 11(4) + 197 - 135.07, will not be 180 at b = 4.

trey had 440 songs on his mp3 player.now he has 473 songs.what is the percent of increase in the number of songs on his mp3 player?
round to the nearest tenth if necessary.
Answers
Answer:
There is 7.5% increase in the number of songs on his mp3 player.
Step-by-step explanation:
Original Songs in mp3= 440 songs
Final Songs in mp3= 473 songs
We need to find percent of increase in the number of songs on his mp3 player.
The formula used is: [tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100[/tex]
Now putting values and finding percent of increase
[tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%[/tex]
So, there is 7.5% increase in the number of songs on his mp3 player.
3(4x+2)=8x+24−2x hhhhhhhh
Answers
Answer: x=3
Step-by-step explanation:
1. First lets do the parenthesis 3(4x+2) to get 12x+6
2. 12x+6=8x+24-2x (combine like terms) first lets do 8x and 2x first so its 8-2= 6x
3. 12x+6=6x+24 (now subtract 12x by 6x to get 6x)
4. 6x+6= 24 (now subtract 24 by 6 to get 18)
5. 6x= 18 (now divide 18 by 6 to get 3)
Answer:
x = 3Step-by-step explanation:
[tex]3(4x+2)=8x+24−2x[/tex]
Expand and simplify
We have
[tex]12x + 6 = 8x + 24 - 2x \\ 12x + 6 = 6x + 24[/tex]
Move 6x to the left side of the equation
[tex]12x - 6x + 6 = 24 \\ 6x + 6 = 24[/tex]
Move 6 to the right side of the equation
[tex]6x = 24 - 6 \\ 6x = 18[/tex]
Divide both sides by 6
[tex] \frac{6x}{6} = \frac{18}{6} \\ [/tex]
We have the final answer as
x = 3Hope this helps you

Find the root of the following equation: (6+x)2−x2=168
Answers
Answer:
No solutions (roots)
Step-by-step explanation:
The root of an equation is basically the solution of the equation. If I'm reading the problem correctly, the equation is (6+x)*2 - x*2 = 168.
We distribute the (6+x)*2 part and get 12+2x - 2x = 168. Uh oh.. the 2x terms cancel each other out and we are left with 12=168. Either I'm reading the equation wrong or the equation has no solutions.

Explanation: The number marked by the dot is 1.25. To convert decimals to fractions, think of it as a percent. 1.25% is like 125% (out of 100%) so that would be 125/100. Then divide by GCD (greatest common divider). GCD must be a multiple of both 125 and 100. The GCD in this case is 25. So divide numerator (125) and denominator (100) by 25 to get 5/4.

Answer:
<A = 117degrees
Step-by-step explanation:
<A and <B are verticle angles, as given. Hence they will be of equal measures. It is given that <A = 5x -3, and <B = 4x + 21.
Using this, set up an equation;
<A = <B
5x - 3 = 4x + 21
Inverse operations,
5x - 3 = 4x + 21
+3 +3
5x = 4x + 24
-4x -4x
x = 24
Now substitute back in, to find the measure of <A,
