Predict what you will see at the end of your experiment in part C. How would these results demonstrate fossilization? (Image just in case)
Answer:
The fossils would look weird and sometimes they might not be the exact shape as before because they've grown with the earth meaning they're going to come out of the ground go back under and what not, Its hard to tell how deep a fossil can be in the ground because of how many years ago it was because how much the earth has grown.

a man is 3 times as old as his son. the sum of their ages is 48 years, how old is the son?
Let the sons age = x
The dads age would be 3x ( 3 times the sons age)
X + 3x = 48
Simplify:
4x = 48
Divide both sides by 4
X = 12
The sons age is 12
The sum of a number and seven more than the number is 43. What is the number?
Answer:
18
Step-by-step explanation:
we can use the variable x to represent the number since it's currently unknownseven more than the number can be represented as x + 7we can find the sum of both by adding themx + x + 7 = 43
2x + 7 = 43
-7 -7
2x = 36
we divide by 2 on both sides to isolate xx = 18
The figure shows a block of stone measures 8 cm by 5 cm by 2 cm and has a density of 2.5 g/cm3
what is the volume of the stone?
what is the mass of the stone?
Step-by-step explanation:
The volume of the stone = 8 × 5 × 2 = 80
Using density = mass / volume
So 2.5 = mass / 80
2.5 × 80 = mass
200 = mass
please give me brainliest answer
volume:
(8cm×5cm×2cm)=80cm³

Solve:
x + y = 7
3x - 2y = 11
By using Substituting method.
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\sf \longmapsto x + y = 7 \: \: - - - (i)[/tex]
[tex]\sf \longmapsto 3x - 2y = 11 \: \: - - - (ii)[/tex]
By first equation,
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x = 7 - y[/tex]
Now, we can find the original value of y.
[tex]\sf \longmapsto 3x - 2y = 11[/tex]
[tex]\sf \longmapsto 3(7 - y) - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 3y - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 5y = 11[/tex]
[tex]\sf \longmapsto - 5y = 11 - 21[/tex]
[tex]\sf \longmapsto - 5y = - 10[/tex]
[tex]\sf \longmapsto y = \dfrac{ - 10}{ - 5} [/tex]
[tex]\sf \longmapsto y = 2[/tex]
Now, we can find the original value of x.
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x + 2 = 7[/tex]
[tex]\sf \longmapsto x = 7 - 2[/tex]
[tex]\sf \longmapsto x = 5[/tex]
Therefore, the values of x and y are 5 and 2 respectively.

Answer:
0.8
Step-by-step explanation:
just use guess and check. Divide each of the constants by the width of one point. When you find a constant that matches, try that out with all the other widths, if it works with the other widths, then you found the right constant!

Answer:
1)
Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.
2)
Let x be the number of miles.
Then, we have inequality: 8x+2<=10
Solve the inequality: 8x+2<=10
Subtract 2 from both the sides:
8x+2-2<=10-2
Simplify
8x<=8
:
Divide by 8 both sides we get
x<=1;
as shown in figure 1.
4)
From the context of the problem :
we can say that Paul can travel 1 miles or less before reaching his limit of $10.

Evaluate 1/2(x divided by 4)+y when x = 16 and y = 2/5 A. 4/5, B. 19/10, C. 12/5, D. 32/5
The expression 1/2(x divided by 4)+y when evaluated for x = 16 and y = 2/5 is 12/5
How to evaluate the expressionThe mathematical statement of the expression is given as
1/2(x divided by 4)+y
When the above expression is expressed using proper mathematical operators
We have the followng expression
1/2(x/4) + y
From the question, we have the followng values
x = 16 and y = 2/5
This means that
1/2(x/4) + y = 1/2(16/4) + 2/5
When evaluated, we have
1/2(x/4) + y = 12/5 or 2.4
Hence, the value of the expression si 12/5
