Answer:
a) Josef jogging from A to B;
i. speed = 2 m/s
ii. velocity = 2m/s
a) a) Josef jogging from A to C;
speed = 1.9 m/s
ii. velocity = 2.2 m/s
Step-by-step explanation:
One major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.
a) Josef jogging from A to B;
distance = 300 m
time = 2.5 seconds = 150 seconds
i. his average speed = 
= 
= 2 m/s
ii. his average velocity = 
=
= 2 m/s
b) Josef jogging from A to C,
distance = 300 + 100 = 400 m
time = 2.5 + 1 = 3.5 minutes
= 210 seconds
i. his average speed =
= 
= 1.9 m/s
ii. his average velocity = 
= 4 m/s
= 1.9 m/s
his average velocity = 
= 2.2 m/s
Answer:
$25.98
Step-by-step explanation:
Add the items Sara buys to find the total:
17.50 + 6.50 = 24
Convert 8.25% into a decimal:
8.25/100 = 0.0825
Multiply 0.0825 by 24:
0.0825 x 24 = 1.98
1.98 is the amount of tax, then add the tax to the total amount you got before tax.
24 + 1.98 = 25.98
Your answer would be 25 dollars and 98 cents!

Answer:
Step-by-step explanation:
In order to find the area of a square you take the base and multiply it by the height.
Base x Height = Area
In this case you have 7cm as the base and 6cm as the height.
All you have to do after that is multiply the two together.
Make sure that you remember to put the unit (cm) and make sure that it is 
because some teachers are uptight about that stuff.
