Answer:
Step-by-step explanation:
a) (2,350),(5,530)
b) (530-350)/(5-2)=60
c) y=60x+b, using point (2,350)
350=60(2)+b
b=230
w=60t+230
c) w(7)=60(7)+230
w(7)=$650
Answer:
Please check the explanation.
Step-by-step explanation:
a)
As there are 1000000 units in 1 million
i.e.
1 million = 1000000 units
A house as purchases for $6780000.
Thus, the purchase price in million will be:
6780000/1000000 = 6.78 million
b)
purchase price in millions nearest to an integer
As the number we are rounding is followed by 7, so will be round the number up.
Therefore,
$6780000 rounded to the nearest million = $7,000,000
63 books every 6 hours=> 63/6 x booklets in 9 hours => x/9 so, 63/6 = x/9 and your answer is A.
Answer:
2880
Step-by-step explanation:
The "." or · means multiplication.
"!" means multiplying every consecutive positive whole number starting from 1 until the number infront of the "!". It's called a <u>factorial</u>.
4! = 1·2·3·4 = 24 The factorial of 4
5! = 1·2·3·4·5 = 120 The factorial of 5
Substitute the values of the factorials, then multiply them to solve.
5! · 4!
= (1·2·3·4·5) · (1·2·3·4)
= 120 · 24
= 2880 Answer
Therefore 5!·4! = 2880.
