Answer:
She sneezed for 138.286 weeks in a row. You need days of week to create a proper conversion.
Step-by-step explanation:
There are 7 days in a week. There are 978 days shown.
You can depict it as this:
978 = 7x; x is the amount of weeks.
Divide both sides by 7
138.285714 = x
Round to three decimals
x = 138.286
Angle 6 = angle 7 = 61⁰, as vertical angles
Angle 5 = angle 8, as vertical angles
angle 6+angle 7 + angle 5 + angle 8 =360
61+61 + angle 5 + angle 8 =360
angle 5 + angle 8 = 360 - 61*2 = 238⁰
Answer D. 238⁰
Answer:30km/hr
Step-by-step explanation:
Total distance=294km
Speed=s
Distance=d
Time=t
First drive:
t=5
d=s x t
d=s x 5
d=5s
Second drive:
t=4
Speed is 6km/h greater than the first speed
The new speed= s+6
d=4(s+6)
Total distance=294
5s + 4(s + 6)=294
5s + 4s + 24=294
Collect like terms
5s + 4s=294 - 24
9s=270
Divide both sides by 9
9s/9=270/9
s=30
First speed=30km/hr
Answer:
57
Step-by-step explanation:
180-123=57
that line the angle is on is a straight line and a straight line is 180 degrees
