Cupid's arrow travels 45 meters in 5
seconds. What is the speed of the
flying arrow?
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

Im struggling in math rn and i need help with this problem 3 1/4 = 1/2 + w
Answer:
w= 2 3/4
Step-by-step explanation:
First, we need to find what can equal w. So, we can subtract 1/2 form both sides, so one sides has just w and one side has just a number. 3 1/4-1/2= 2 3/4. So w= 2 3/4
Answer:
2 3/4
Step-by-step explanation:
3 1/4 = 1/2 + w
Transfer 1/2 to other side
3 1/4 - 1/2 = w
Solve
w = 2 3/4

length of rectangle = ( 4n-5 )
breadth of rectangle = ( 3n-2)
To find :-Area and perimeter of rectangle.
solution :-by the question ,
We know the area of rectangle = length × breadth
Area = (4n -5) (3n-2)
[tex] = {12n}^{2} - 8n - 15n + 10[/tex]
[tex] = {12n}^{2} - 23n + 10[/tex]
now ,
perimeter = 2 ( length + breadth (
= 2 ( 4n-5 + 3n-2)
= 2 ( 7n-7)
= 14n -14

A bracelet that regularly sells for $44 is on sale for 15% off. Find the sale price of the bracelet. Use dollar signs with your answer. *
Answer:
The answer would be $37.40
Step-by-step explanation:

It is 15 percent off, so 44 x 0.85 would be the equation, since the now price is 85 percent of the original price.
44 x 0.85 = 37.40

Answer:
y = 7x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 7 and c = - 5, then
y = 7x - 5 ← equation of line

What are integers?
Please give your best explanation and a simple example (worth 20 points)
Integer is a subset of Real Number. It can be broken into these following:
Positive IntegerZeroNegative IntegerInteger can be any whole numbers. Keep in mind that Integers cannot be fractions, decimal, approximate value, etc. Integers can only be something like 1,2,3,-1,-2,0.
Integers are like Natural or Counting Numbers except they have 0 and negative numbers.
Positive IntegerPositive Integers are basically a natural or counting number. It starts from 1 to any positive countable infinity. Here is the example of positive integer: 1,2,3,4,5,6,7,...
ZeroZero is just a number 0. It is between the negative and positive. 0 is neither positive or negative but it is categorized as Zero.
Negative IntegersNegative Integers are opposite of Positive Integers. The opposite of plus is minus and the opposite of minus is plus. Negative Integers are less than both 0 and Positive Integers. Here is the example: -1,-2,-3,-4,-5,...
Integers are whole numbers with a positive or negative counterparts.
If that doesn't make sense let me make some examples
-4, 100, 9300 would be integers. Using my definition they all have negative or positive counterparts.
-2.3, 7.8888(etc.) 2/3 would not be integers. Even though -2.3 and 7.8888(etc.) have negative/ positive counterparts they are not whole numbers.
Hope that helped!
