Answer:
9.025 inches
Step-by-step explanation:
Let the length be represented by:
[tex]L = mt+L_0[/tex]
Where [tex]L[/tex] is the length of candle at time [tex]t[/tex]
[tex]m[/tex] is the rate at which the candle is burning.
And [tex]L_0[/tex] is the initial length of the candle.
As per the question statement, let us put the given values in the equation.
[tex]11.2 = m\times 33 + L_0 .... (1)\\10.75 = m\times 51+L_0 ..... (2)[/tex]
Subtracting (1) from (2):
[tex]0.45 = -18m\\\Rightarrow m = -0.025[/tex]
Putting the value of [tex]m[/tex] in the equation (1):
[tex]11.2 = -0.025 \times 33+L_0\\\Rightarrow L_0 = 12.025[/tex]
Therefore, the equation becomes:
[tex]L = -0.025t + 12.025[/tex]
Now, we have to find the height of candle after 2 hours.
2 hours mean 120 minutes.
[tex]L = -0.025 \times 120 + 12.025\\\Rightarrow L = 9.025\ inches[/tex]
Therefore, the height of candle is 9.025 inches.

Answer:
588
Step-by-step explanation:
In a factor tree, I mostly like to look from down to up so that I can track down the non-square number. In a square number, there must be two factors that are exactly the same as each other, and when multiplied gives that square number.
So based on the 5 × 5, 2 × 2, and 7 × 7, we can tell that 25, 4 and 49 are all square numbers. We move up one level. Since the factors of 196 are square numbers, 196 is also a square number since it consists of 2² × 7².
We move another step up. 588 consists of 3 and 196. We know that 196 is a square number, but 3 is a prime number, which means that 3 only has a factor of 3 and itself. Thus, 588 is not a perfect square number since there should be a double factor for 3.

Candy = $ 0.5
Soda = $ 4.0
Step-by-step explanation:
x + 2y = 5
x + 4y = 6
2y = 1
y = 1/2
= two candies were added and the price increased by 1 dollar, meaning that the a single candy is 0.5 dollar
1 candy = 0.5
x + 2(0.5) = 5
x + 1 = 5

Frank is having the car pets in his house cleaned. The cost of the cleaning is calculated from the area of the carpets. C= the cost of the cleaning a= the area of the carpets. Which of the variables is independent which is dependent?
Answer:
Cost of the cleaning, C is the dependent variable
Area of the carpet, a is the independent variable
Step-by-step explanation:
cost of the cleaning is calculated from the area of the carpets
C= the cost of the cleaning a= the area of the carpets.
Cost of the cleaning, C is the dependent variable
Area of the carpet, a is the independent variable
A dependent variable is a variable which depends on other factors to exist. They take their values based on other factors. Their value is changed as a result of a change in independent variable
An independent variable is a variable which does not change as a result of the change in other factors. They take their values irrespective of external factors around them.

The line f(x) = x is graphed in the xy-coordinate plane.
How does the graph of the function f(x) + 1 compare to the graph of f(x)?
Answer:
Please check the attached diagram.
Thus, we conclude that:
In the diagram,
The red line represents the parent function f(x) = xThe blue line represents the function f(x) = x+1The blue line indicates that the parent function has been shifted 1 unit upward.
Step-by-step explanation:
Let us recall some transformation knowledge.
We know that
if y = f(x), then y = f(x) + b simply means a transformation of (0, b).
In other words, if we add some constant let say 'b' in the output or y-value, the graph simply shifts upward by b units.
Given that
f(x) = x
so
f(x+1) = x+1 means the parent function f(x) = x has been shifted 1 unit upward.
Please check the attached diagram.
Thus, we conclude that:
In the diagram,
The red line represents the parent function f(x) = xThe blue line represents the function f(x) = x+1The blue line indicates that the parent function has been shifted 1 unit upward.
Mimi and her friend went to the Burger Barn for lunch. Their bill
totaled $24.68. They left a 15% tip for their waitress. How much
tin did they leave
Answer:
they tipped = 15% of 24.68 = 15/100*24.68 = 3.702
Step-by-step explanation:
Answer:
Tip: $3.70
Total: $28.38
Step-by-step explanation:
bill: $24.68
tip: 0.15 * 24.68 = $3.70
Total: 24.68 + 3.70 = $28.38
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second. y=-16x^2+218x+75
Answer:
6.81s
Step-by-step explanation:
First you must know that the velocity of the body is zero at the maximum height.
v =dy/dx
v= -32x+218
Since v = 0
-32x+218 =0
32x =218
x= 218/32
x = 6.81s
Hence the rocket reaches its maximum height after 6.81s

Choose two numbers from this list: 3, 4, 6, 12. Explain the difference between finding the greatest common factor and the least common multiple of the two numbers.
Answer:
Please check explanations for answer
Step-by-step explanation:
Let us choose 4 and 6
When we talk of the greatest common factor, we mean the highest number that is a factor of both numbers
The factors of 4 are 1,2,2 and 4
Factors of 6 are 1,2,3 and 6
So as we can see the only common factors to both are 1,2 but the highest here is 2
The least common multiple refers to the smallest number which divides 4 and 6 at the same time without leaving a remainder
Multiples of 4 are 4,8,12 , 16,20 •••••
multiples of 6 are 6,12,18,24
As we can see, the lowest common number to both is 12

*BRAINIEST & 20 POINTS*
i only have 2 chances so please get it correct!!!
Answer:
(-4, 5)
Step-by-step explanation:
partitions 1 to 4 means that point will make part of the line where it is 1 part to the other 4 parts. This means there are a total of five parts.
For x, we go from -7 to 8 or 15 units, and we are 1/5 of that distance so 3 units, add that to -7 we get -4.
For y, we go from 8 to -7, or 15 units, and we are 1/5 of that distance so 3 units, subtract that from 8 we get 5.

Find the value
[tex](2x)0[/tex]
[tex] \bf {(2x)}^{0} = 1[/tex]
The rule is that any number raised to the power of 0 equals to 1.
So if 2 or 1,000,000 is raised to the power of 0 it equals 1.
But 0 to the power 0 is undefined!
0 to any positive power is 0, so 0 to the power 0 should be 0. But any positive number to the power 0 is 1, so 0 to the power 0 should be 1. We can't have it both ways. Underlying this argument is the same idea as was used in the attempt to define 0 divided by 0.

Ziad tells his son Marc: " This year my age is triple yours, but in 10 years, it will be the double". Find their ages.
Answer:
Ziad is 30 years old.
Marc is 10 years old.
Step-by-step explanation:
We will use m to represent Marc's age this year, and z to represent Ziad's age this year.
This year:
z = 3m
To show their relative ages in ten years time:
z + 10 = 2(m+10)
We can rearrange this to make m the subject.
z + 10 = 2m + 20
z = 2m + 10
We also know that m = 3z. We can substitute this value into our equation.
3m = 2m + 10
m = 10
Use z = 3m to find that z = 30.

ANSWER PLEASE !!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!
Answer:
62 degrees
Step-by-step explanation:
First, it is important to note that all three angles in a triangle add up to be 180 degrees, and if you draw a straight line extending off the side of a triangle, the outside angle and the inside angle are supplementary (they add to be 180 degrees). So,(3x+3)+(2x+4)-180=measure angle F, and 180-(7x-5)=measure angle F according to the rules respectively. Since both of these equations are equal (they both equal the measure of angle F) we can set them equal to each other to find the value of x=> 180-(7x-5)=(3x+3)+(2x+4)-180=> 180-7x-5=3x+3+2x+4-180. Now combine like terms=>175-7x=5x-173. Now, add 7x to both sides and add 173 to both sides to get the variables on one side of the equation=> 175+173-7x+7x=5x+7x-173+173 (the 7x and -7x on the left side and the 173 and -173 on the right side cancel out) =>348=12x. Divide both sides by twelve to find x=> 29=x. Now, plug 29 into what is given for angle FDE=> 2(29)+4=
58+4=
62 degrees
