Answer:
Total number of people in the stadium = 520
Step-by-step explanation:
Let the total number of people in the stadium = x
Since, 25% of the fans are teenagers, number of teenagers in the stadium
= 25% of x
= 
= 0,25x
If the number of teenagers in the stadium = 130
0.25x = 130
x = 
x = 520
Therefore, total number of fans in the stadium = 520.
Answer:
Complementary angle 1st = 66.3°
Complementary angle 2nd = 23.7°
Step-by-step explanation:
Assume;
Complementary angle 1st = a
Complementary angle 2nd = a - 42.6°
Sum of complementary angles = 90°
So,
a + a - 42.6 = 90
a = 66.3
Complementary angle 1st = 66.3°
Complementary angle 2nd = 23.7°
<span><span>2/7 times 2 by 5 and times 7 by 5 also then that would equal 10/35
then you times 3 by 7 and times 5 by 7 to get 21/35 then add 10 and 21 to get 31 then it will be 31/35 then try to reduce it but u cant so the answer is 31/35</span></span>
Answer:
Initial deposit P = 4,801 (Approx.)
Step-by-step explanation:
Given:
Amount after 4 year = 5,300
Number of year = 4 year
Rate = 2.5% = 0.025
Find:
Initial deposit
Computation:
A = P[1+r]ⁿ
5,300 = P[1+0.025]⁴
5,300 = P[1.025]⁴
5,300 = P[1.1038]
Initial deposit P = 4,801 (Approx.)
<h3>
Answer: A) around 80 cm</h3>
=========================================
Explanation:
The perimeter around the circle, aka circumference, is found through this formula
C = 2*pi*r
That's for a full circle. However, we're dealing with semicircles here, so we cut that in half to get pi*r to represent the curved distance around half the circle.
For the outer larger semicircle, that curved distance is exactly 14pi
For the inner smaller semicircle, that curved distance is 7pi, since 7 is half of 14.
The total curved portions is 14pi+7pi = 21pi
Then we add on the last straight line portion that's 14 cm long to get a total perimeter of 21pi+14
This is the exact perimeter in terms of pi.
The last thing to do is replace pi with 3.14 and simplify
21pi+14 = 21*3.14+14 = 79.94
This value rounds to 80
