A(b)=10*((b+7)/2)
A(b)=5(b+7)
b+7=A/5
b=A/5 - 7
B(a) = a/5 - 7
Answer C.
Answer: 5
Step-by-step explanation: The answer is 5 since "median" means the middle. If you count the numbers you get 13. Since 13 isnt even you count half of 12 which is 6 then count 6 on both sides, youll end up with 5 not fitting into the group. Im not the best at explaining so im sorry! Hope this helps!
Answer:
394 m
Step-by-step explanation:
From the solution diagram attached ;
The distance between boat and base of hill is represented as d ;
Using the trigonometric relation :
Tan θ = opposite / Adjacent
Tan 13 = 91 / d
Tan 13 * d = 91
d = 91 / Tan(13)
d = 394.16 m
d = 394 m (nearest meter)
translate, call the number, n
Eight more than (8+) twice a number increased by 3 (2(n+3)) is equal to (=) 79 (79)
8+2(n+3)=79
minus 8 both sides
2(n+3)=71
divide both sides by 2
n+3=35.5
minus 3 both sides
n=32.5
the number is 32.5
Answer:
11. 9hrs
12. 5hrs 35min
13. 3hrs 48 min
Step-by-step explanation:
Makes it a bit easier if you convert to 24 hr time.
11. 10 - 19 is 9hrs
12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min
13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min
