Answer: 1.567 × 10⁹
Step-by-step explanation:
1.6 × 10⁹ = 1.6 × 1000000000 = 1,600,000,000
3.3 × 10⁷ = 3.3 × 10000000 = 33,000,000
1,600,000,000 - 33,000,000 = 1,567,000,000
10⁹ = 1,000,000,000
1.567 × 1,000,000,000 = 1,567,000,000
Hope this helps!

I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75
Answer:
3 : 5
Step-by-step explanation:
Given 2 similar figures with linear scale factor = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 9 : 25 , thus
linear ratio =
:
= 3 : 5
Answer:
- 10
- 15ab
Step-by-step explanation:
1. The square of the binomial is ...
(* -2m)^2 = *^2 -4m* +4m^2
Matching terms, you find ...
*^2 = 100
-4m* = -40
Both of these equations tell you the value of * is 10.
___
2. Same deal. Multiply ou the square and see what you have.
(3a +2.5b)^2 = 9a^2 +15ab +6.25b^2
The term missing on the right side of the given equation is 15ab.
