Answer:
5 un^2
Step-by-step explanation:
the liens from (0, 0) to (1, 3) and (1, 3) to (4, 2) are perpendicular meaning that the angle at (1, 3) is a right angle
to find the lengths of the sides we must use the pythagorean theorem
a^2 + b^2 = c^2
for the leftmost side
we have 1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
for the top side
we have
the same thing
1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
you must multiple sqrt(10) by sqrt(10) and then by 1/2
sqrt(10) * sqrt(10) is 10
10 * 1/2 is 5
the area is 5 un^2
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
Answer:
The total weight is 5kg
Step-by-step explanation:
Given
See attachment for box plot
Required
Determine the total weight of the kitten
First, we represent the plot in the following table where the number of dots represent the frequency.
So, we have:
Multiply the weight by the frequency, then add up the result
So, we have:
Express as improper fraction
Take LCM
Let x = number
2(x-2)=3(x+6)
2x-4=3x+18
2x-3x=18+4
-x=22
x=-22
Try this solution; note, the basic formula is Distance=Speed*Time.
All the details are in the attachment.
