n = -5
Write in the scientific notation form, m × 10n
= 7.396 × 10-5

So what we gotta do is isolate the variable by
writing it out like this
4 1/4 25 those are the numbers where those go are like this
4x - 1/4 < 25 then move on to the next line on here we write out
4x + 1/4 - 1/4 < 25 + 1/4 (The reason why i put + 1/4 is because you have to isolate the variable by doing addition as well And i always find it easier to convert the fractions to decimals then after you make that line you make the next one like this you have to add 1/4 to 4x then take it away (which is 4x) then put that to the side like this 4x ? ? then we need to find those two ?s by adding 25 and 1/4 (or o.25) which is 25.25 then we need to add that to the second answer 4x ? 25.25 when you have this you need to find out which one is bigger so it is 4x<25.25 (or 25 1/4) then we need to divide 4 and 25.25 to get 6.25 so
the answer is x < 6.25 so c is your awnser

Cupid's arrow travels 45 meters in 5
seconds. What is the speed of the
flying arrow?
Answers
Answer:9
Step-by-step explanation:
45/5 =9
s=d/t
The speed of the flying arrow will be 9 meters/second.
What is the relation between speed and distance?Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.
The speed formula is speed = distance/time.
We are given that Cupid's arrow travels 45 meters in 5 seconds.
Therefore, distance = 45 meters
Time= 5 seconds.
Thus, speed = distance/time
Speed = 45/5
Speed =9

There are cows and turkeys at a farm, 82 heads and 264 legs in all. There is no need to explain that a cow has four legs, while a turkey has two legs. How many cows and turkeys are at the farm? How can I solve this using elimination or substitution can I have steps please. No spamming please
Answers
Cows+turkeys=82
4 cow legs + 2 turkey legs = 264
C+T=82
-T. -T
—————
C= 82-T wherever you see a “C” substitute this formula
4C+ 2T=264
4(82-T)+ 2T=264
(82*4)- (4T+2T)= 264
328-2T=264
-328. -328
————————
-2T= -64
-2T/-2= -64/ -2
T=32 there are 32 turkeys
There are 82 heads total
If we know there are 32 turkeys then the rest have to be cows.
82-32=50

B. The number of siblings each student in a class has
C. Weights of sumo wrestlers
D. The length of a movie
The answer is B! Lucky guess
Answers
Answer:
this is right
Step-by-step explanation:
i just took the test and it was B!
The discrete data is option B.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive
A. Continuous data example would be the distance between two cities, which may take on any value along a continuous scale.
C. Another example of continuous data is sumo wrestler weights, which can take on any value along a continuous scale.
D. Another example of continuous data is movie duration, which can have any value along a continuous scale.
B. An example of discrete data is the number of siblings each student in a class has. The only possible values for discrete data are generally integers. The number of siblings a student has in this situation can only be a whole number, making it discrete data.
