If you would like to know how long would it take John to mow the lawn alone, you can calculate this using the following steps:
hours (Jessica) ... a
hours (John) ... b = ?
a + b = 11
b = 4 * a
___________
a + b = 11
a + 4 * a = 11
5 * a = 11 /5
a = 11/5 = 2 1/5 = 2.2 hours
b = 4 * a = 4 * 2.2 = 8.8 hours
The correct result would be 8.8 hours.
Answer:
slope = 5/2
Step-by-step explanation:
This equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 5/2x -3
The slope is 5/2 and the y intercept is -3
Answer:
The largest pizza is Rectangular Pizza .
Step-by-step explanation:
In order to know which pizza is the largest you have to find the area for each shape using the formulas :

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
When the product of two integers is a positive number, you either kept all positives after multiplying or multiplied a negative and a vegative.
When the product of two integers is a negative number, you multiplied a negative and a positive.
