Answer:
B. 1.2×10^-3 mm
Step-by-step explanation:
What constitutes an "appropriate" unit depends on the use of the number. Since we're not told of any particular use, we might choose the smallest of the available units: mm.
1.2×10^-3 mm
_____
Additional comment
The most appropriate unit would be the one that eliminates the power-of-ten multiplier:
= 1.2 µm

what are congruent angles written as?
Answers
Answer:
Congruent angles are two or more angles that have the same measure. In simple words, they have the same number of degrees. It's important to note that the length of the angles' edges or the direction of the angles has no effect on their congruency. As long as their measure is equal, the angles are considered congruent.
Step-by-step explanation:
hope this helps!
Answer:
Look at the attachment below: that is the congruence symbol.
Suppose you want to write Angle A is congruent to Angle B, then you would write it like this :
∠A ≅ ∠B
Or if you want to write Angle F is congruent to Angle Y, then you would write it like this:
∠F≅∠Y

Use a number line to add the following: 14 + (-11)
Add.
Answers
Adding a negative number is the same as subtracting a positive number.
14 + (-11) = 14 - 11
We start at the point 14 on a number line.
Since we are subtracting, we are going to left -11 units on the number line.
We will land on the point "3"

How many integers satisfy the inequality (x 2 – 4)(x 2 – 10) < 0?
Answers
Answer:
2 integers (2 and -2)Step-by-step explanation:
Given the inequality (x²– 4)(x² – 10) < 0, we are to find the number of integers that satisfies the inequality
From (x²– 4)(x² – 10) < 0, (x²– 4)< 0 and (x² – 10) < 0
For (x²– 4)< 0;
x²<4
take the square root of both sides;
√x²<√4
x < ±2
x<2 and x<-2
Similarly for (x²– 10)< 0;
x²<10
take the square root of both sides;
√x²<±√10
x < ±√10
x<√10 and x<-√10
Note that √10 is not an integer but an irrational number. An integer should be a negative or positive whole number. Therefore the amount of integers that satisfies the equation is 2 i.e 2 and -2

A car travels at a constant speed of 30.0 m/s for 0.8 hr. Find the total distance traveled in km
Answers
Answer:
0.8 hr = 0.8*3600 seconds = 2880 seconds
d = 30*2880 meters = 8640 meters
d = 8.64 km
Step-by-step explanation:
hope this helps
The total distance traveled in km is 86.4 km
From the question,
We are to determine the total distance traveled in km.
First, we will determine the distance traveled in m.
Distance traveled can be calculated using the formula
Distance = Speed × Time
From the given information,
Speed = 30.0 m/s
Time = 0.8 hr = 0.8 × 60 × 60 s
Time = 2880 s
Putting the parameters into the formula, we get
Distance = 30.0 × 2880
Distance = 86400 m
Now, we will convert from meters (m) to kilometers (km)
NOTE: 1000 m = 1km
If 1000 m = 1km
Then,
86400 m will be [tex]\frac{86400}{1000}[/tex] km
[tex]\frac{86400}{1000} =[/tex] 86.4 km
Hence, the total distance traveled in km is 86.4 km

One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?
The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.
