Answer:
b. 67
Step-by-step explanation:
In order for the average to be 62, the total of differences from 62 must be zero. The two given numbers have differences of -4 and -1, for a total of -5. In order for the total of differences to be zero, the third number must have a difference from 62 of +5. It must be 62+5 = 67.
Jon's height at his third checkup was 67 inches.
You cannot simplify this expression, but instead, you can factor it like this:
Find the Greatest Common Factor (GCF) of the three numbers.
Since the GCF is 2, we can factor 10, 6, and 6 by dividing them by two and placing them inside parenthesis.
When you multiply 2 to each of the terms, you would end up with 10a + 6b + 6c.
Answer:
Option D
Step-by-step explanation:
From the spinner we see there are 5 colours in there.
These are;
Green, Yellow, Red, Purple, Blue.
This means that when it is spinned, there's possibility of getting only one colour per spin.
Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.
This means, all possible outcomes will be 5 × 2 = 10 outcomes.
With each colour possibly showing up with either tail or head.
Correct answer is Option D as it has 10 possible outcomes in the correct order.
Answer:
The circumference of the clock is 
Step-by-step explanation:
we know that
The circumference of a circle (clock) is equal to
In this problem
The long of the minute hand is the radius of the circle
so
substitute
-----> exact value of the circumference
(3a-7)^2
1. 9a^2-21a-21a+49
2. 3a(3a-7)-7(3a-7)
3. (3a-7)(3a-7)
4. Combine like terms
