.
5. 17.2
6. 2.2
7. 3.3
8. 7.9
Step-by-step explanation:
When calculating square root, you always need to find a number multiplied by itself twice that gives the number
Example:
What number multiplied by itself twice gives 64? Number 8! because 8 × 8 = 64
Now cube root is a little bit different. This time, you will need to find a number multiplied by itself three times that gives that number.
Example:
What number multiplied by itself three times gives 125? Number 5! because 5 × 5 × 5 = 125
Hope this helps!
Dwight's salary after t year is represented by
<h3><u><em>Solution:</em></u></h3>
Given that
Dwight has a new job that guarantees a six percent raise for each year with the company.
His initial salary is $52,000 per year.
Need to determine equation which models Dwight's salary after t years
Dwight's initial salary = $52,000 per year.
As job guarantees a six percent raise for each year
Dwight's salary after 1 year = 52000 + 6% of 52000 = 52000 + 0.06 x 52000 = 52000 (1.06)
Dwight's salary after 2 year = (52000 x 1.06) + 6 % of (52000 x 1.06)
Hence Dwight's salary after t year is represented by =
Answer:
y = 5 - 4x is linear because the x is to the power of 1.
Answer:
171
Step-by-step explanation:
Step 1: Let "x" and "y" be the variables
Let x = the number of adult tickets sold
Let y = the number of child tickets sold
Step 2: Add the variables and subtract the "x" variable
x + y = 486 y = 486 - x
Step 3: Add the given amounts by the variables next to it to equal the total
5.50x + 4y = 2416.50
5.50x + 4(486 - x) = 2416.50
5.50x + 1944 - 4x = 2416.50
Step 4: Subtracting the result from the number of tickets the booth sold
1.5x = 472.5
x = 315
y = 486 - 315 = 171
Therefore, there are 171 tickets of each type sold.
