Answer:
1 triangle por minute
Step-by-step explanation:
1/4 of an hour is 15 min (60/4=15)
Answer: X=136 degrees
Explanation: A triangle has a total of 180 degrees measuring all 3 angles. 180-90-46 gives me 44 left, then subtract 44 from 180 and that gives you 136 degrees.
#1. 5(t+3)=-10
5t+15=-10
5t=-25
t=-5
#2. -(c-10)=0
-c+10=0
c=10
#3. -10(s+3)=-15
-10s-30=-15
-10s=15
s=-3/2
#4. 5(f-5)=-60
5f-25=-60
5f=-35
f=-7
#5. -5(2t+2)=-70
-10t-10=-70
-10t=-60
t=6
#6. 4(3w+2)/3=-6
12w+8=-18
12w=-26
w=-13/6
#7.Substitute the °C with -8
Equation:
5/9(F-32)=-8
divide both sides by 5/9
F-32= -14.4
add 32 to both sides
F=17.6
Answer: -8°C in °F is approximately 18°F.
BTW, to get the degree sign, it's option+shift+8.
So if Bill runs 10 miles in those 4 days then we need to find out Val's.
2 and 3/5. Well, we already know 2*4=8
so 0.6 (which is 3/5) multiplied by 4 is 2.4.
8+2.4=10.4
So here are the results for the distance covered in 4 days :
Val = 10.4 miles
Bill = 10 miles
Therefore, I think Val covers the most distance in 4 days.
Hope I helped :)
