Answer:
a) 5, 6
b) 8, 9
c) 9, 10
Step-by-step explanation:
It is useful to know the squares of small integers:
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81
10² = 100
Then the problem becomes one of identifying the perfect squares the given number lies between
a) 25 < 35 < 36 ⇒ 5 < √35 < 6
b) 64 < 67 < 81 ⇒ 8 < √67 < 9
c) 81 < 93 < 100 ⇒ 9 < √93 < 10
Answer:
9 rolls
Step-by-step explanation:
The perimeter of the room measures 2(19' +12') = 62', so the area of the walls is ...
(62 ft)(8.5 ft) = 527 ft²
We know that 8 rolls will cover 8×60 ft² = 480 ft², and 9 rolls will cover 540 ft², so we will need 9 rolls to cover the walls.
Ok so which intercept? y or x
Answer: The required ratio is 1:1.
Step-by-step explanation:
Let the total number of CDs be 100
of CDs is given by
According to question,
of her Jazz CDs represents of all her CDs.
Let the number of Jazz CDs be x
So, it becomes
So, Number of Jazz's CDs is 50
Number of Jazz non CDs is given by
Ratio of her CDs to her non- CDs is given by
Hence, the required ratio is 1:1.
Answer:
204 Seconds
Step-by-step explanation:
Step 1 - 68/2 this is to find the unit cost in seconds that it takes to walk up the stairs to get 34.
The 2 is from the amount of flights of stairs you have to walk up to get from floor 1 to floor 3.
Step 2 - 34*6 this is because the unit price is 34seconds/flight of stairs to get 204.
Answer 204 Seconds.
