well if you know the unit rates
12 mph=Terrance
8 mph=Jesse
so to find Sandra just simplify
(8*60)/(45*1)(miles/hour
= (480/45)mph)
so 10 2/3 miles per hour
hope I was helpful
Answer:
1/2 scoops of strawberry ice cream is used for 1 scoop of vanilla ice cream
Step-by-step explanation:
New milkshake recipe calls for 12 scoops of vanilla ice cream for every 6 scoops of strawberry ice cream. How many scoops of strawberry ice cream are used for each scoop of vanilla ice cream?
From the above question:
12 scoops of vanilla = 6 scoops of strawberry
1 scoop of vanilla = x scoops of strawberry
Cross Multiply
12 × x = 1 × 6
x = 6/12
x = 1/2 scoops.
Therefore, 1/2 scoops of strawberry ice cream is used for 1 scoop of vanilla ice cream
Answer:
3 hours
Step-by-step explanation:
D=4H+35
47=4H+35
47-35=4H
12=4H
H=3
Answer:
102
Step-by-step explanation:
We have the mean (m) 128.5 and the standard deviation (sd) 8.2, we must calculate the value of z for each one and determine whether or not it is an outlier:
z = (x - m) / sd
In the first case x = 148:
z = (148 - 128.5) /8.2
z = 2.37
In the second case x = 102:
z = (102 - 128.5) /8.2
z = -3.23
In the first case x = 152:
z = (152 - 128.5) /8.2
z = 2.86
The value of this is usually between -3 and 3, therefore when x is 102 it goes outside the range of the value of z, which means that this is the outlier.
