Here we are finding the area of the given
The area of a rectangle is
A = L*W
The image shows that we have to find the area of the two rectangles total
so
Total A = (L1*W1) + (L2*W2)
Total A = (4 * 6) + (3 * 2)
Total A = 24 + 6
Total A = 30
The total area of the given figure is 30 sq. cm.
Hope this helps :)
If JJ decided to leave a tip that is 15% of the original price for his meal, he should leave $1.2 as tip for the $5.50 cheeseburger and $2.50 milkshake.
<h3>How to calculate discount?</h3>
According to this question, JJ bought a $5.50 cheeseburger and a $2.50 milkshake.
This means that in total, JJ purchased $5.50 + $2.50 = $8 worth of meal.
If he decided to leave a tip that is 15% of the original price of his meal, hence,
15/100 × $8 = $1.2
Therefore, if JJ decided to leave a tip that is 15% of the original price for his meal, he should leave $1.2 as tip for the $5.50 cheeseburger and $2.50 milkshake.

The speed of the object is 12121 m per week.
What does it mean to do speed?
- “Speed” is a street name for various stimulant drugs that teens, young adults and others use to feel more alert and focused, and in some cases, to feel high.
- Some people also use various forms of speed to reduce their appetite. Types of speed include: Amphetamines (used to treat ADHD, narcolepsy, and depression)
The object is moving at a speed of 2 centimeters every 7 seconds.
We need to find the speed in m per week.
2 cm = 0.02 m
1 week = 604800 s
7 s = 
Speed = distance/time
So,
or v = 12121 m/ week
So, the speed of the object is 12121 m per week.

Step-by-step explanation:
Multiply the factors
The highest exponent is 3, so the degree is 3
Answer:
Step-by-step explanation:
Two groups were tested to compare their speed at working math problems.
Aim/Objective of experiment:
To test their speed (each group and then compare) at working math problems
Control Group:
The group of students computing math problems without a calculator
Experimental Group:
The group of students computing math problems with a calculator
Statistical Hypothesis:
Null hypothesis: Both the control and the experimental group worked math problems at the same pace or speed
Alternative hypothesis: The experimental group worked math problems with a greater speed than the control group
This hypothesis is derived from the thought or knowledge that calculators help solve math problems faster. Your hope would be to refute the null hypothesis and accept the alternative hypothesis; after testing.
