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!
Let us rephrase this statement: Fabiola's dog weighs 5 pounds more than one-third of Luisa's dog. The dog that Fabiola owns weights 23 pounds.
This is the equation for Fabiola's dog's weight: 1/3f + 5 = 23
I have no understanding what the diagram means.
The circumference of a circle is 2PiR
We have 32Pi, so we can divide 32 by 2 to get the radius
The radius is 16.
The diameter is 2x the radius.
The diameter is 32.
Your answer is B.)
