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
Interval notation or standard?
Answer:
Pretty sure it is 18 girls
Step-by-step explanation:
81 girls: 72 boys
72 boys /16 boys = 4.5
81 girls / 4.5= 18 girls
so 18 girls:16 boys
pls mark me brainliest :)
the answer will be around 53.398
Area of a circle= r^2*pi
Are of whole circle=16pi=50.26548246(to8d.p.)
Area of shaded sector= 16pi(the area of the circle)*(75/360)=10.47197551, because you're looking for 75°(out of 360°) worth of area
