Answer:
420 Mile's.
Step-by-step explanation:
First you figure out the unit rate by dividing 360 by 6 which is 60. So that's 60 miles per hour. Now multiply 60 by 7 to find out how many miles she will drive in 7 hours. When you multiply you get 420.

Answer:
let the price of a glass of milk be m and the price of seafood dinners to be s
A. for the first equation , we can see that
3m+5s =38.5 ........1
and second equation
m+2s= 15.15........2
B. 3m+5s= 38.5 ......1
m+2s=15.15 .......2
using substitution method
make m subject in eqn 2
m= 15.15 - 2s
put m in eqn 1
3(15.15-2s) +5s=38.5
45.45 -6s+5s =38.5
-6s +5s =38.5 -45.45
-s= -6.95
divide both sides by -1
s = $ 6.95
m= 15.15 -2s
m= 15.15- 2(6.95)
m= 15.15 -13.9
m=$ 1.25
therefore the price of a glass of milk is $1.25 and the price of a seafood dinner is $6.95
There are two ways you could go about solving this.
You could divide the length of the base (6mm) by 2 and use that to find the area or you could find the area of the whole triangle using 6mm and divide that by 2.
I will use the first method I described:
base = 6/2
base = 3 mm
height = 5.2 mm
area = bh/2
area = (3 * 5.2)/2
area = 7.8 square mm
(don't forget your units)
Using the other method would look like this:
area = bh/2
b = 6
h = 5.2
area = (6 * 5.2)/2
area = 15.6 square mm
area/2 = 7.8 square mm
As you can see either method yields the same result.
Hope this helped.
Cheers and good luck,
Brian
Answer:
It is a random sample
The second sample is more representative of a population
The second sample gives better representation because it is larger
Step-by-step explanation:
According to the given statement we have been given two statements and we have to determine how often people in a community listen to the local radio station each month.
If you notice the second sample it is a random sample because people who visited the store had equal probability of being chosen.
The second sample is more representative of a population because it is a larger sample than the first sample and the sample are taken from the only local grocery store.
The second sample gives better representation because it is larger ...
