In a study of bat migration habits, 240 male bats and 160 female bats have been tagged. If 100 more female bats are tagged, how
valentinak56 [21]
Remark 
The way you have to set this up is to take the new number for the males and put it over the total for the males and females. The new number for the males / total = 3/5.

Step One
Find the total number of females
100 + 160 = 260 when 100 females have been added to the study.

Step Two 
Find the number of males
The total number of males = 240 + x where x is the number of males to be added.

Step Three
Find the total for both
260 + 240 + x = Total
500 + x = Total.

Step Four
Find the ratio of males to total
(240 + x) / (500 + x) = 3/5   

Step Five
Cross multiply and solve
(240 + x)*5 = (500+x)*3
1200 + 5x = 1500 + 3x    Subtract 1200 from both sides.
5x = 1500 - 1200 + 3x     
5x = 300 + 3x                   Subtract 3x from both sides.
5x - 3x = 300
2x = 300                          Divide by 2 
x = 300  / 2
x = 150

Check
(240 + 150 ) / (500 + 150) = ? 3/5
390 / 650 = ? 3/5
39/65 = ? 3/5  Divide the top and bottom on the left by 13
3/5 = 3/5 and it checks.

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz
rusak2 [61]

Answer: 1/40

Step-by-step explanation:

Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:

= 3 3/4 + 2 3/5

= 3 15/20 + 2 12/20

= 5 27/20

= 6 7/20

We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:

= 6 3/8 - 6 7/20

= 6 30/80 - 6 28/80

= 2/80

= 1/40

Can someone pls tell me how to do this?
gizmo_the_mogwai [7]
Ok don’t worry this is a very easy topic
It falls under “gradients of a straight line”
I’ll try my best to explain the question but u can find plenty of videos online (Fuse School or Cognito) explaining the topic in detail.

Gradient means slope or how steep a line is.
To find the gradient we use the formula

(Change in y) / (change in x)

*Step 1*
Choose any two coordinates (exact) of the line from the graph

For line 1 let’s take
(2,4) (-3,4)
Now from this
the change in y= (4-4) = 0
the change in x = (-3-2) = -5
So the gradient = 0/-5 = 0

*Now this makes sense because a straight horizontal line has no slope and thus has a gradient of zero. So even without all the calculation we can figure this out easily.

Now for line 2 let’s take the coordinates:
(-3,1) (-3,3)

The change in y= (3-1) = 2
The change in x = (-3- -3) = 0
So gradient = 2/0 = “Undefined”

*The gradient of vertical straight line is always undefined (no gradient)*
*The gradient of horizontal straight lines is always 0*

Hope this helped and best of luck for your exams!
