Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean = 
= 
= 17
Noe find the mean of 25 and 17 and 17 and 9
mean = 
= 
= 21 and
mean = 
= 
= 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
(40+x)/2=60
40 +x = 120
x = 80
check :
40+80 = 120
120/2 = 60
so his second round needs to be 80 mph
Answer:
x=104
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
10.5 = 1/2( x-83)
Multiply each side by 2
2* 10.5 = 2*1/2( x-83)
21 = x-83
Add 83 to each side
21+83 = x-83+83
104 =x
Sometimes it helps to draw it...so u can see
7 7
J_______K_________L
|__________________|
4x - 2
since K is the midpoint, it splits the segment in 2 equal parts
JK + KL = JL
7 + 7 = 4x - 2
14 = 4x - 2
14 + 2 = 4x
16 = 4x
16/4 = x
4 = x <====
KL = 7 <===
JL = 4x - 2....4(4) - 2.....16 - 2 = 14 <==
Answer: 375 is a composite number. Prime factorization: 375 = 3 x 5 x 5 x 5, which can be written 375 = 3 x (5^3) The exponents in the prime factorization is 1
