2nd one I just did the math
Answer:
The slope is 7/5
Step-by-step explanation:
Here, we want to find the slope of the line
We use the slope equation
m = (y2-y1)/(x2-x1)
m = (35-70)/(25-50) = -35/-25 = 7/5
what it means is that the rate of change of the number of red drops to number of blue drops to form the purple color is in the ratio of 7 to 5
Or simply put
To form a purple color, add 7 part red to 5 parts blue drops
Ok so first we need to write a fraction.
75 percent/45 mins
then we convert that into a unit rate
1.67 percent/1 min
so, now that we have the unit rate, we know exactly how fast she is moving.
Now, we divide 25 by 1.67 because 25% is the distance between the completion of the gate and current state of the gate.
So we get 14.97, which we can safely round up to 15.
It will take her 15 mins more to finish the gate, and it has already taken 45, so 45+15=60
60 MINS TOTAL/ 1 HOUR
Answer:
AHH! Geometry!
14.1375
Step-by-step explanation:
So to get the answer, we are going to have to make a "factor"
We first do this:(Circles have an angle of 360)
This tells how long the arc is in comparison to the circumference!
So let's solve the circumference!
Now, Multiply!
There we go!
Hope this helps!
See Ya!
Answer:
7 * 1/8
Step-by-step explanation:
7 is a whole number
A unit fraction has the top number equal to 1, so we can use 1/8
