Answer: it would be 1.4
Step-by-step explanation: 2.75 times 4 is 11 and 12.4 minus 11 equals 1.4
H^2=x^2+y^2
9^2=4^2+x^2
81=16+x^2
x^2=65
x=8.1cm
Answer:
b
Step-by-step explanation:
Answer:
A)60°
Step-by-step explanation:
a straight line is 180° then
if a line bisect it in to a half it become 90°
then
the exterior angle of a triangle is equal to the sum of two interior angles
this means 150°-90°=60°
<span> Train1 = 85 mph</span>
Train 2 = 105mph
85+105 = 190 mph combined speed
Time = distance/ speed
Time = 456/190 = 2.4 hours = 2 hours and 24 minutes
