Answer:
therefore, he had 181 digital cameras at first
Step-by-step explanation:
total=240
digital= 3x+82
manual= x+26
total= digital + manual
240= 3x+82+26+x
x= 240-108/4
x= 33
digital= 3×33+83
=181
279ft/9sec = xft/1sec
Cross multiply to get
9x = 279 divide by 9
x = 31
31 feet per second
Answer:
$401.55
Step-by-step explanation:
Given:
Pat's ending balance on his debit card last month was $233.55,<u> we can consider it as opening balance for this month as carry forwarded.</u>
This month he had $542 worth of purchases.
This month he had $710 worth of deposits.
Question asked:
What is his ending balance for this month ?
Solution:
We can easily find the ending balance by subtracting purchase amount as it will reduce the balance and we will add deposits as it increase the balance of debit card.
Opening balance of debit card = $233.55
Purchases worth of = $542
Deposit worth of = $710
<em><u>Ending balance for this month = Opening balance of debit card + Deposit - Purchases </u></em>
Ending balance for this month = $233.55 + $710 - $542
= $943.55 - $542 = $401.55
Therefore, the ending balance for this month in his debit card is $401.55
Answer:
Third option: 5.48
Step-by-step explanation:
Given the quadratic model that represents the approximate height in meters of the ball
. the time in seconds x, when the ball is 50 meters from the ground can be calculated by substituting
and solving for x.
Then:

Subtract 200 from both sides:

Divide both sides by -5:

Apply square root to both sides:

The ball is 50 meters from the ground after about 5.48 seconds.
