Used a speed formula.
s=d/t
s=30miles/2hours
Answer is= 15 miles per hour.
Hope it helped you.
Answer:
B. 6,-6
Step-by-step explanation:
X^2 + 12 = 48
Subtract 12 from each side
X^2 + 12-12 = 48-12
X^2 = 36
Take the square root of each side
sqrt(X^2 ) = sqrt(36)
X = ±6
The answer is 66.75
I would suggest multiplying 2 in (2x+1) by 2 5/8 first, then multipling 4 by 2 5/8. This will garner you 10 and 5.25. Distribute the 9 into the (). You'll then get 10.5+47.25+9
Add and you will get 66.75
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
Vcylinder-vcone=vair
vcylinder=hpir^2
vcone=(1/3)hpir^2
vcylinder=16*pi*5^2=400pi
vcone=(1/3)12*pi*4^2=64pi
vylinder-cone=400pi-64pi=336pi
volume is 336pi cubic centimeters or aprox 1055.5 cubic cm
