Answer:
2.3 mL
Step-by-step explanation:
This is called finding the volume by displacement. By subtracting the final volume and the initial volume you can determine how much the volume changed when the object was added. That change in voulme represents the volume of the object, so in this case:\
14.5-12.2 = 2.3 mL
The change in the volume of the object is, 2.3 mL.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
We have to given that;
An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .
Here, An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .
Hence, The change in the volume of the object is,
⇒ 14.5 - 12.2 mL
⇒ 2.3 mL

b. 48 books bought for $360 is at the rate of _______ per book.
c. If 900 litres of water flows through a tap in 2 hours, it is the rate of _____ per minute.
d. Richard works for 10 hours and is paid $145. His rate of pay is _____ per hour.
e. 5kg of peas cost $12.58, which equals _____ per kg.
Answer:
a. 64
b. 7.5
c. 7 min 5 sec
d. 14.5
e. 2.52
The rate per hour is known as the average speed.
Average speed = total distance / time
320 / 5 = 64 km / hr
The rate per book is the cost of one book.
Cost of one book = total cost of the book / number of books bought
$360 / 48 = $7.50
The rate per minute = total litres / total minutes
900 / (2 x 60)
900 / 180 = 5 litres per minute
Rate pay per hour = total amount earned / total hours worked
$145 / 10 = $14.50 per hour
Cost per kg = total cost of the peas / total weight of the peas
$12.58 / 5 = $2.52 per kg

When Susan babysat for 8 hours and did odd jobs for 3 hours, she made a total of $39. When she babysat for 2 hours and did odd jobs for 5 hours, she made a total of $31. How much does she charge per hour for babysitting and for doing odd jobs?
Answer:
x = charge for babysitting = $3
y = charge for doing odd jobs = $5
Step-by-step explanation:
Let
x = charge for babysitting
y = charge for doing odd jobs
8x + 3y = 39 (1)
2x + 5y = 31 (2)
Multiply (1) by 5and (2) by 3
40x + 15y = 195 (3)
6x + 15y = 93 (4)
Subtract (4) from (3)
40x - 6x = 195 - 93
34x = 102
Divide both sides by 34
x = 102 / 34
= 3
x = $3
Substitute x = 3 into (1)
8x + 3y = 39
8(3) + 3y = 39
24 + 3y = 39
3y = 39 - 24
3y = 15
y = 15 / 3
= 5
y = $5
x = charge for babysitting = $3
y = charge for doing odd jobs = $5

1) What type of slope is shown? *
negative
positive
Answer:
hi! so the way I do this is I hold my hand out and do a ninja chop! I know this is weird but it's helpful or you could remember right and left!
anyways your line is "chopping" or leaning right which means you use your right hand not your left to recreate this line right is positive!
so this would be positive if it was negative it would go to the left and if you're using your hand to "chop" like a knife then you would use your left hand because your line would lean to the left
not sure if the chop method works for everyone but you could always remember right is positve and left is negative
update: found this weird picture but this is basically what I mean when I say chop LOL
