8.62/12 =0.72
Therefore 1 sticker costs $0.72 and 18 would cost 18×0.72= $12.96
Answer:
a) P(gray slice) = Number of grayscale/Total no. favorable chances =
b)P(gray slice less than 9) =
We want to find the speed of the hyper loop if it takes 11 minutes from Dubai to Abu Dhabi. We will find that the speed is 761.75 km/h
<h3>
Working with speeds.</h3>
Remember the relation:
speed = distance/time.
Here we know that the time is 11 minutes (the time in which the distance is traveled) and the distance will be the distance from Dubai to Abu Dhabi, which we can find online.
The distance is 139.4 km
Now, we know that:
1 hour = 60 minutes.
Using this we can write the time in hours.
11 min = (11 min/60min) hours = 0.183 hours
Now we can just compute the speed:
S = (139.4 km)/(0.183 h) = 761.75 km/h

Answer:
shorter base = 6 yd
longer base = 8 yd
area of playground = 42 yd^2
Step-by-step explanation:
The question tells you that the shorter side is equal to the width, which is 6 yds. The bases of the triangles on either side are 1 yd. Since there are two, add 1 twice to 6 (6+1+1). This gives you 8 yd for the longer base. You're right about the area, just use the trapezoid area formula: 1/2h(a+b).
