Answer:
2.72 x 10^4
Step-by-step explanation:
2.4 x 10^4
= 24000
3.2 x 10^3
= 3200
Therefore,
(2.4 x 10^4) + (3.2 x 10^3)
= 24000 + 3200
= 27200
= 2.72 x 10^4
Minus 2 degrees every hour
there are 4 hours
d=degrees dropped
- 2 x 4 = d
Answer:
Number of dogs = 6
Number of burgers = 11
Step-by-step explanation:
Number of dogs = x
Number of burgers = 2x - 1
Cost of a dog = $ 1.50
Cost of 'x' dogs = 1.5x
Cost of a burger = $ 2
Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2
= 4x - 2
Total amount collected = $ 31
1.5x + 4x - 2 = 31 {add 2 to both sides}
1.5x + 4x = 31 + 2
1.5x+ 4x = 33
5.5x = 33
x = 33/5.5
x = 6
Number of dogs = 6
Number of burgers = 2*6 - 1 = 12 - 1 = 11
Answer:
x¹²
Step-by-step explanation:
You need to indicate which terms are exponents. For example, (x⁴)³ can be written as (x^4)^3.
(x⁴)³ = x⁴*³ = x¹²
