Answer:
A =16.25 cm^2
Step-by-step explanation:
The area of a triangle is given by 1/2 bh where b is the base and h is the height
A = 1/2 (5) * 6.5
A =16.25 cm^2
Answer:
i think the answer is 8/12 but im not sure though
Step-by-step explanation:
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5
Her speed is minutes per foot or feet per minutes, so we have 10 minutes/-200 feet=-1/20 feet. Since it doesn't matter that it's negative (we care about the speed, and you can't have negative speed), we get the absolute value (1/20). For the next 20 minutes, we have |20 minutes/-300 feet|=1 minute/15 feet. Since 1/20=0.05 and 1/15 is 0.0666667, 1/15 is clearly higher and the 20 minute portion was at a faster rate
V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in
V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3
