1. solid and liquid
2. Evaporation changes liquid water to water vapour.
for #1: for example, it's raining, when it rains, the rain is water (liquid).
Or it's snowing, the snow is solid.
for #2: for example, when you are making tea, you need hot water, so you add heat, then the water lessens because it's transforming to gas, and sometimes you can see it.
Answer:
1. solid and liquid
2. water vapor (gas)
Grace is an hourly employee
Answer:
full question Grace is an hourly employee, and the line that models her total pay in dollars
as it relates to the number of hours she has worked has a slope of 45 and a y
intercept of 35. Which statement is true?
A. Grace's wage is $35 an hour, and it appears that she received a
signing bonus of $45.
B. Grace's wage is $35 an hour, but it appears that she received no
signing bonus.
C. Grace's wage is $45 an hour, and it appears that she received a
signing bonus of $35.
D. Grace's wage is $45 an hour, but it appears that she received no
signing bonus.
Step-by-step explanation:
if x is the amount of hours worked, 45 is the slope and the y intercept is 35.
A linear equation has the form of y = ax + b, where a is the slope and b is the y-intercept, then the equation that we have is:
y = 45*x + 35
this means that she wins $45 per hour, and has a plane amount of $35, indiferent of the amount of hours worked.
Then the correct answer is
C) Grace's wage is $45 an hour, and it appears that she received a signing bonus of $35.

Answer:
36 x⁸y⁶
√2/2
Step-by-step explanation:
Factor 1296 into its prime factors
1296 = 24 • 34
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
Factors which will be extracted are :
1296 = 24 • 34
No factors remain inside the root !!
To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :
36 = 22 • 32
At the end of this step the partly simplified SQRT looks like this:
36 √(x¹⁶y¹²)
STEP2:Simplify the Variable part of the SQRT
Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
√(x⁸)=x⁴
√(x^-6)=x^-3
Applying these rules to our case we find out that
SQRT(x¹⁶y¹²) = x⁸y⁶
Combine both simplifications
sqrt (1296x¹⁶y¹²) = 36 x⁸y⁶
Simplified Root : 36 x⁸y⁶

What is the exact area of a circle having diameter 3 in.?
Answer:
7.065 in^2
Step-by-step explanation:
Answer:
7.06858...in²
if we are using 3.14
7.065in²
Step-by-step explanation:
3 / 2 = 1.5
A = πr²
A = π(1.5²)
A = π(2.25)
A = 7.068in²
(if we are using 3.14 for pi)
A = πr²
A = 3.14(1.5²)
A = 3.14(2.25)
A = 7.065in²

bag contains eight red marbles and
seven blue marbles. You randomly pick a
marble and then pick a second marble
without returning the marbles to the bag.
The first marble is red and the second
marble is blue.
The probability of getting first marble is red and the second
marble is blue is 4/15.
What is probability?
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes.
Given that:
Number of red marbles= 8
Number of blue marbles= 7
Total Number of marbles= 8+7 = 15 marbles.
P(red Marble) =[tex]\frac{8}{15}[/tex]
No replacement, now the total marbles = 14
P( blue marbles) = 7/14
Now, P( first marble is red and the second marble is blue.)
= 8/15*7/14
= 4/15
Hence, the probability of getting first marble is red and the second
marble is blue is 4/15.

Answer:
50
Step-by-step explanation:
to find the mean you have to add all the number up together. then divide that number by how many numbers it is in all:
48+50+5+60+37+50=300
divide 300 by 6= 50
Answer: it is the first choice which is 50 .
Step-by-step explanation: to find the mean it means you have to find the average total so you will have to add them together and divide by 6 as they are 6 numbers . When you add them the answer is 300 , divide by 6 the answer is 50 .

Lea and adam are selling cheesecakes for a school fundraiser. customers can by new york cheesecakes and chocolate marble cheesecakes. lea sold 14 new york cheesecakes and 11 chocolate marble cheesecakes for a total of $293. adam sold 7 new york cheesecakes and 2 chocolate marble cheesecakes for a total of $80. what was the cost for one chocolate marble cheesecake?
Answer: $19
Step-by-step explanation:
We will set up equations to solve and pull the information we need from the given passage. Let x be new york cheesecakes and y be chocolate marble.
Lea sold 14 new york and 11 chocolate marble. She made $293 total.
14x + 11y = 293
Adam sold 7 new york and 2 chocolate marble for $80 total.
7x + 2y = 80

What is the mode of the following numbers?
6, 4, 1, 9, 3, 8, 3, 5, 10
Explanation:
The mode is the most frequent number. It is the number that shows up the most.
Sorting the values gets us {1, 3, 3, 4, 5, 6, 8, 9, 10} in which we can see that "3" shows up twice, which is the most compared to any other value. Therefore the mode is 3.

What is the volume of a sphere with a diameter of 8.6 m, rounded to the nearest
tenth of a cubic meter?
Consider the diagram.
2 triangles are connected at their hypotenuse to form a rectangle. The rectangle has a length of 7 meters and width of 6 meters.
Mia plans to build a fence to divide her rectangular garden into two triangular areas. Use the diagram to find the length of fence she will need to divide the garden. Round up to the nearest hundredth.
Mia will need a fence that is
meters long.
The length of fence she will need to divide the garden is 9.22 m.
What is a Rectangle?A Rectangle is a quadrilateral having four sides and four right angles in which both sides are parallel and opposite to each other.
Pythagoras TheoremThe Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared.
Let us consider the length of the fence be 'x'
Using Pythagoras Theorem,
x² = 6² + 7²
[tex]x^{2} =36+49\\x^{2} = 85[/tex]
x = 9.22 m
So, the length of fence is 9.22 m.
