Answer:
the answer is 4 hours.
Step-by-step explanation:
x: time clark drove
Y: Mitchells time drove
60 times Y = 75 times x
y=x+1
60(x+1)=75x
60x+60=75x
60=15x (subtract the 60x to the other side)
60/15=4
x=4
The difference between both points is 8
Answer:
NaCl=500m (1L/1000mL) (9.0 grams /L) (1/2)
Mass NaCl = 2.25 grams
Therefore, 500mL of 1/2 Na solution has 2g of NaCl.
Answer:
m = -6
Step-by-step explanation:
The area of the triangular base is
A = (1/2)bh
A = (1/2)(5 units)(12 units)
A = 30 units²
The "height" of the prism is 6 units, so the volume is
V = (area of base)×(height)
V = (30 units²)×(6 units)
V = 180 units³
The appropriate choice is
A. 180 units³
