Riki cuts two decagons out of cardboard.Then he glues yarn around theedges. How much yard does riki use if each edge of the decagon is 8 centimeter?
Answer:
0.00736 Sq. Yard size of decagon is used
Step-by-step explanation:
Given
Each side of Decagon [tex]= 8[/tex] centimeter
Area of Decagon
[tex]A = \frac{5}{2} a \sqrt{5+2\sqrt{5} }[/tex]
Here a is the side of decagon
Substituting the given values, we get -
[tex]A = 2.5 * 8 * 3.077\\A = 61.54[/tex]Square centimeter
1 square centimeter = 0.000119599 square yard
Area in yard = 0.00736 Sq. Yard

-6|4p+2|+8 > -34
Answer
p>5/4 or p<-9/4
Step-by-step explanation:
1. first isolate the absolute value by subtracting 8 and then dividing by -6
2. you then split the absolute value inequality into 4p+2>7 and 4p+2<-7
3. When you solve those, you get p>5/4 and p< -9/4
Answer:
[tex] - \frac{9}{4} < p < \frac{5}{4} [/tex]
Step-by-step explanation:
1) Subtract 8 from both sides.
[tex] - 6 |4p + 2| > - 34 -8[/tex]
2) Simplify -34 - 8 to -42.
[tex] - 6 |4p + 2| > - 42[/tex]
3) Divide both sides by -6.
[tex] |4p + 2| < \frac{ - 42}{ - 6} [/tex]
4) Two negative numbers makes a positive.
[tex] |4p + 2| < \frac{42}{6} [/tex]
5) Simplify 42/6 to 7.
[tex] |4p + 2| < 7[/tex]
6) Rewrite the inequality without the absolute value.
[tex] - 7 < 4p + 2 < 7[/tex]
7) Subtract 2 from the whole equation.
[tex] - 7 - 2 < 4p < 7 - 2[/tex]
8) Simplify.
[tex] - 9 < 4p < 5[/tex]
9) Divide the whole equation by 4.
[tex] - \frac{9}{4} < p < \frac{5}{4} [/tex]
Therefor, the answer is - 9/4 < p < 5/4.

Tell whether the rates are equivalent. Justify your answer.
60 centimeters every 2.5 years
30 centimeters every 15 months10
Answer:
30 centimeters every 15 months is correct the other one isnt.
Step-by-step explanation:
The rates are equivalent, and we can justify this by converting the time units to make a valid comparison.
To determine if the rates are equivalent, we need to compare the ratios of centimeters to time between the two rates.
Rate 1: 60 centimeters every 2.5 years
Rate 2: 30 centimeters every 15 months
Let's convert both rates to a common time unit to make a valid comparison. We can convert years to months or months to years.
Converting Rate 1:
2.5 years * 12 months/year = 30 months
Rate 1 becomes 60 centimeters every 30 months.
Now, let's compare the rates:
Rate 1: 60 centimeters every 30 months
Rate 2: 30 centimeters every 15 months
The rates are equivalent because the ratios of centimeters to time are the same for both rates. In both cases, the ratio is 2 centimeters per month.
Therefore, the rates are equivalent, and we can justify this by converting the time units to make a valid comparison.

Step-by-step explanation:
. If the measures of angles A and B of triangle
ABC are each 2x + 5 and the measure of angle
C is 3x – 5, what is the measure of angle exterior
to angle A?
Using the theorem
The sum of interior angle of a triangle is equal to its exterior
Given the interior angles 2x+5 and 3x-5
Sum= 2x+5+3x-5
Sum = 2x+3x+5-5
Sum = 5x+0
Sum = 5x
Hence the measure of the exterior angle is 5x
5(y+ 2/5) = -13

Answer:
14 is A
15 is B
Step-by-step explanation:
14 . the answer is a because first off the slope is negative so we can immediately eliminate B and D second of all the slope is 1/2 so we can eliminate D and get that the answer has to be a
15. answer is B for this one because first of all the slope is negative so we can immediately eliminate A and c and second of all the y-intercept would be 120 because 90 is what x=1 so we would have to add 30 to get what y would equal when x=0 if that makes sense
Two of it of his favorite buildings are Chicago Sears Tower and the Dubai's Burj Khalifa. If Burji Khalifa stands 830 meters high and Sears tower stands 527 meters high , how much higher is Burji Khalifa than Sears tower
Answer: 303 meters
Step-by-step explanation:
The Burji Khalifa is 830 meters in height and the Sears tower is 527 meters in height.
To find out how much higher the Burji Khalifa is than the Sears tower, subtract the height of the Sears tower from the height of the Burji Khalifa:
= 830 - 527
= 303 meters
