The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue. In 100×10 the 100 is the number of decks and the 10 is the price per deck. In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck. So a must be the amount the price increases.
Answer: amount of price increase, last choice
-149 would be your answer
Answer:
<u>10 ft.</u>
Step-by-step explanation:
<u>Scale</u> ⇒ 1 in. : 2 ft.
- 1 in. : 2ft. = 5 in. : x ft. [x is the width of the real statue]
- 1/2 = 5/x
- x = 5 × 2
- x = <u>10 ft</u>.
Answer: There would be 48 shirts launched
To find this answer...
We need to find a unit rate
A unit rate is how many (blank) there is per (blank)
In this case, it would be how many shirts per minute
To find the unit rates all we have to do is 4÷15
4÷15= 0.26 repeated
Now, we can find how many shirts are launched per 3 hours.
We can do 60 × 3 to find the number of minutes in an hour (180)
We multiply 180 by 0.26 to find our final answer
180 × 0.26 = 48 (rounded)
Hope this helps!
This is an incomplete question. Here is the complete question:
Attila the Hun was a ruler of the Hunnic Empire. The Romans feared him greatly until his death since he made quite a habit of invading. The Romans no longer feared him after his death in 453. Let x represent any year. Write an inequality in terms of x and 453 that is true only for values of x that represent years after the year that Attila died.
Answer:
Step-by-step explanation:
Given:
A year is represented by the variable .
The question says for any year before the death of Attila the Hun, the Roman feared him. But as soon as he died, the Romans were relieved and no longer feared him. Attila died in the year 453.
We are asked to determine an inequality that mentions the years after Attila's death. So, 'x' must be greater than 453 and can't include the year 453 as this was the year of his death.
So, the inequality representing the years after the year that Attila died is:
