What we know:
quotient 9.2 x 10^6/ 2.3 x 10²
in quotients exponents are subtracted of they have the same base, for example 10^6 and 10² have the same base of 10
What we need to find: quotient 9.2 x 10^6/ 2.3 x 10²
9.2 x 10^6
-------------- = 4 x 10^4
2.3 x 10²
Here in this problem I divided 9.2 by 2.3 and got 4, since the solution was simple and clean meaning no repeated decimals I went ahead and divided the 10^6 by 10^2 and got 10^4.
Another method would be to expand both numbers then divide and do scientific notation again.
Remember to change to normal notation you move the decimal to the right using the number of the exponent.
9.2 x 10^6= 9200000
2.3 x 10²= 230
920000/230=40000
40000= 4 x 10^4 scientific notation
Use the method that is best for you or just know you can use either method to check your work.
Answer:
If x equals -1 or anything less than -1, then the inequality statement is false
Step-by-step explanation:
So to find the number x has to be for the statement to be false, we have to find what number x would be to make it so both sides equal the same thing. So in this case, it would be -1 because 5-3 equals 2 and -2x=2 only if x=-1. So anything greater than -1 would make the statement true.
I hope this helped.
Answer: A) reflection C) rotation D) translation
Step-by-step explanation:
A rigid transformation happens when a point or object is moved, but the size and shape remain the same. There are four kinds of rigid transformation.
1) translation 2) reflection 3) rotation 4) glide reflection.
They all create congruent images.
But a dilation is a non rigid motion.
A dilation is a transformation that creates an image that is the exactly same shape as the original, but have a different size.
Answer:
The correct answer is 17.96875 or approximately 18 inches.
Step-by-step explanation:
Since the ratio of the model truck to the real truck is 5:64, and the length of the truck is 230 inches, that means the length of the model truck would be 
= 
= 17.96875 ≈ 18 inches.
