Answer:
a. rotation; then reflection across x
Step-by-step explanation:
The transformation shown is a reflection across the y-axis.
The first part of each answer choice is a rotation 180°. That rotation is fully equivalent to reflection across both the x- and y-axes, in either order. In order to have a net effect of reflection across the y-axis, the reflection across the x-axis must be cancelled--by another reflection across the x-axis.
The reflection across y shown is equivalent to ...
rotation 180° followed by reflection across the x-axis.
Answer:
780.54-455=425.54
Step-by-step explanation:
425.54+1570.85+12.60+9.50=2018.49
The highest place value is in the ten thousand for both of these numbers. Let's round the two numbers first, and then we will add them. Let's round 23,945. So, we need to round to the ten thousand place, so we look at the number behind it (3) and act accordingly.
Remember:
5 or more? Raise the Score
4 or less? Let it Rest
We are looking at the bolded number: 23,945. This number is 4 or less, so we let it rest. So, the new rounded number is 20,000.
Now let's look at 46,718. So, we need to round to the ten thousand place, so we look at the number behind it (6) and act accordingly. Look at the bolded number: 46,718. This number is 5 or more, so we raise the score. The new rounded number becomes 50,000.
Now, all you have to do is add 20,000+50,000, which is 70,000. Hope this helped!
V = ⁴/₃πr³
V = ⁴/₃(3.14)(6)³
V = ⁴/₃(3.14)(216)
V = ⁴/₃(678.24)
V = 904.23cm³
It is equal to 288πcm³.
Answer:
5
Step-by-step explanation:
half of 7 is 3.5 so we round to 4 because we can't have half a bird.
and 2 come back so
7-4+2=5
