Answer:
113.33 km/hr
Step-by-step explanation:
Given that :
From Austin
Drive 1 : Speed of 120km/hr for 1.5 hours
Stop time = 0.5 hour
Drive 2 : speed of v2 for 45 minutes to finally reach Houston
Total distance (Austin to Houston) = 265 km
Total distance : (distance on drive + distance on second drive)
Distance = speed * time
(120 * 1.5) + (v2 * 45/60) = 265
180 + 0.75v2 = 265
0.75v2 = 265 - 180
0.75v2 = 85
v2 = 85 / 0.75
v2 = 113.33km/hr
v2 = 85 / 0.75
v2 =
Answer:
y = - 
x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 6x - 1 ← is in slope- intercept form
with slope m = 6
Given the slope m of a line then the slope of a line perpendicular to it is
= - 
= - , thus
y = - x + c ← is the partial equation
To find c substitute (- 6, 4) into the partial equation
4 = 1 + c ⇒ c = 4 - 1 = 3
y = - x + 3 ← equation of perpendicular line
Answer:
angle relationship: same-side interior
value of x: 40
Step-by-step explanation:
the horizontal lines are parallel and the vertical line is the transversal, so 3x+x+20=180. combine the x's and subtract 20 from both sides to get 4x=160. then divide both sides by 4 to get x=40.
Answer:
2 cups
Step-by-step explanation:
8oz times 3 would be 24oz and that would be all the water if each cup can hold 8oz, so take away 1 cup which would be 2 cups in total of 16oz with a remaining of 8oz
Answer:
2/5 are girls so 40
Step-by-step explanation:
100 divided by 5 is 20.
BOYS: 20 x 3= 60
GIRLS: 20 x 2= 40
60+40=100
Hope this helps (:
