I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250
250+120=370!!
answer : 370 kilometers per hour
11 is 44% of 25 because 25 divided by 11 is 0.44
Answer:
Step-by-step explanation:
Step 1: Subtract -2x from both sides.
x2+x−7−−2x=−2x−−2x
x2+3x−7=0
For this equation: a=1, b=3, c=-7
1x2+3x+−7=0
Step 2: Use quadratic formula with a=1, b=3, c=-7.
x= −b±√b2−4ac / 2a
x= −(3)±√(3)2−4(1)(−7) / 2(1)
x= −3±√37 / 2
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
$509.60 is how much he will make in total.
Step-by-step explanation:
Create an equation from the word problem and solve.
See attached picture.
The answer is D.
Because IM is a bisector HK is the same as HJ
So JK = 3.9 + 3.9 = 7.8
Because IM and JK are perpendicular ( little red square) all corners (IHJ, IHK, JHM, KHM) are 90 degrees.
LHN = 90
