Ok, I can see only a) to c)
a) Lucy spent the most time reading.
b) 20 minutes.
c) 22 minutes.
Step-by-step explanation:
Reason for b):
First convert hours to minutes.
1 hour = 60 minutes
4 hours = ?
4 × 60 = 240 minutes.
Homework is 30°
Total in the pie chart is 360° so:
30/360 × 240 mins = 20 mins
Answer is Zac spent 20 minutes to do his homework.
Reason for c):
Watching TV:
Zac: 135°
Lucy: 102°
Zac:
135/360 × 240 minutes = 90 minutes
Lucy:
102/360 × 240 minutes = 68 minutes
To find how many minutes Zac spent watching TV than Lucy:
90 minutes - 68 minutes = 22 minutes.

Answer:
Down here VVVVVVVV
Step-by-step explanation:
The formula for slope is rise/run there a whole lot of variations of it tho see
(Srry abt my hand writing XD)
rise is basically how far away are the 2 y values from each other
(It will always be positive btw mate.
In this case the rise would be 5
because you need to move up 5 spaces to reach 3 from -2
Now the run which is how far away the 2 x values are from each other.
In this case it would be 4
because you need to move 4 spaces from 3 to reach 7
so it would the slope would be 5/4 :)
This may not be right but you can get the just of how to do it hopefully
Im learning this right now too XD
Answer:
x=-y/2
Step-by-step explanation:
1. The value of a variable that makes an equation true.
2. In chemistry, a solution is a homogeneous mixture composed of only one phase
Easy
compare
y²=4px vs
y²=-4x
y²=y²
4px=-4x
divide both sides by x
4p=-4
divide both sides by 4
p=-1
p=-1
