Answer:
Step-by-step explanation:
s+1+2s-1+90=180 degree(being linear pair)
3s+90=180
3s=180-90
s=90/3
s=30 degree
Jacinda: d = 10 * t ( a rate: 10 miles per hour )
Raj : d = 1.5 + 4.5 * t
Jacinda will catch up with Raj when:
10 t = 1.5 + 4.5 t
10 t - 4.5 t = 1.5
5.5 t = 1.5
t = 1.5 : 5.5 = 0.27 hours = 16.2 min = 16 min 12 seconds
Answer:
x = 3
Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the equation of the axis of symmetry is
x = - 
y = x² - 6x + 
is in standard form
with a = 1 and b = - 6, hence
x = - 
= 3
equation of axis of symmetry is x = 3
Answer:
6.25 minutes
Step-by-step explanation:
First, let's simplify it down. We want to find out how many shirts she can fold in 1 minute, then multiply that by 50.
20 shirts in 2.5 minutes
20 shirts = 2.5 minutes
An equals sign is like a see-saw. If you do something to one side, you have to do it to the other side. To get 20 shirts to 1 one shirt, divide by 20. You have to do that to the other side to make it equal.
(20 divided by 20) = (2.5 divided by 20)
1 shirt = 0.125 minutes.
That's how long it takes to fold 1 shirt. To find the time for 50 shirts, multiply that by 50.
0.125 x 50 = 6.25
It will take Carrie 6.25 minutes to fold 50 shirts. Hope this helped =)
