I believe it’s A and B
Answer:
64
Step-by-step explanation:
a) How far does the earth travel in one orbit about the
sun? That is, what is the approximate circumference of the earth's path?
b) Approximately how fast is the earth traveling in its orbit in space? Calculate
your answer in miles per hour.
a. The circumference should be 186000000π mile
b. The speed of the earth should be 7750000π miles per hour.
Since the radius is 93000000 miles
a.
So, here the circumference is
= 2πr
= 2π(93000000) miles
= 186000000π miles
b) Now the speed is
speed = distance ÷ time
Here the time should be 24 hours
So,
Speed = 186000000π ÷ 24
= 7750000π miles per hour

The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour
A. 4.0 kg
B. 3.0 kg
C. 14.52 kg
D. .33 kg
E. 8.6 kg
The correct weight of the baby is given by option B) 3.0 kg
The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here, the baby's weight as 6.6 lbs and 1 lb=0.45 kg
Thus 6.6 lbs=6.6×0.45
= 3.0 ( approx)
Hence, The correct weight of the baby is given by option B) 3.0 kg

Answer:
B
Step-by-step explanation:
2.2lb = 1 kg
6.6/2.2=3.0kg
The best classification for the number -4 is an integer.
A number is a basic component of mathematics. A number is an arithmetic value which is used to represent the quantity of an object. Numbers are used for counting, measuring, keeping things in order, indexing, etc.
For the given situation,
The number is -4.
We have different types of numbers based on their properties such as natural numbers, whole numbers, rational and irrational numbers, integers, real numbers, complex numbers, even and odd numbers, etc.
Based on the properties of numbers, -4 can be classified as an integer or a real number or a rational number or a negative number or even number.
Among these the best classification for -4 is an integer.
Hence we can conclude that the best classification for the number -4 is an integer.
