Answer:
starting with 6 and adding 3 an hour over two days or 48 hours that would be 3x48= 144 then add your original 6 that would be 150
Step-by-step explanation:
6 + (3x48) = logs for two days
6 + 144 = 150
150!!!
a. The number of logs needed for one night can be represented by the expression:
6 + 3h
b. The expression for the number of logs needed for 2 nights is 12 + 6h.
What is an expression?A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.
If Nelson plans to start the fire with 6 logs and add 3 logs for each hour the fire burns, then the number of logs needed for one night can be represented by the expression:
6 + 3h
where h is the number of hours the fire burns.
To find the number of logs needed for 2 nights, we can simply multiply the number of logs needed for one night by 2:
2(6 + 3h)
Simplifying this expression gives:
12 + 6h
So the expression for the number of logs needed for 2 nights is 12 + 6h. This represents starting the first night's fire with 6 logs, adding 3 logs per hour for that night, and then starting the second night's fire with 6 logs again, and adding 3 logs per hour for that night as well.

Step-by-step explanation:
Length, Area, and Volume Scale Factors
If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is [tex]a^2:b^2[/tex] and the scale factor of their volumes is [tex]a^3:b^3[/tex].
We are given the scale factor of the surface areas of two similar containers A and B as 4:25.
The length scale factor is
[tex]\sqrt{4}:\sqrt{25}=2:5[/tex]
The volume scale factor is: [tex]5^3:2^3[/tex] = 125:8 = 15.625
Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

Given: tangent A = negative StartRoot 15 EndRoot What is the value of Tangent (A minus StartFraction pi over 4 EndFraction)?
Answer:
( √15 + 8)/7
Step-by-step explanation:
TanA = -√15
.we are to find tan(A-π/4).
In trigonometry
Tan(A-B) = TanA - TanB/1+ tanAtanB
Hence:
tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4
Substitute tan A value into the formula
tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4
tan(A-π/4) = -√15-1/1-√15
Rationalize
-√15-1/1-√15 × 1+√15/1+√15
= -√15-√225-1-√15/(1-√225)
= -2√15-15-1/1-15
= -2√15 -16/(-14)
= -2(√15+8)/-14
= √15 + 8/7
Hence the required value is ( √15 + 8)/7

Three friends order a pizza for $14, a two-liter bottle of soda for $2.75, and a bag of chips for $2.15 They want to evenly split the total cost. Determine how much each person owes.
Answer:
$6.3
Step-by-step explanation:
Given that:
There are 3 friends who have ordered some eatables.
Price of one pizza = $14
Price of two-liter soda bottle = $2.75
Price of a bag of chips = $2.15
The price of all the items is split evenly.
To find:
How much each person owes i.e. the amount of money each person will have to pay?
Solution:
First of all, let us find the total amount to be paid for all the three items.
Total amount to be paid = $14 + $2.75 + $2.15 = $18.9
Now, this total amount is evenly split i.e. equally divided in three parts.
Let us divide the total amount by 3.
Therefore, share of each friend = [tex]\frac{\$18.9}{3} = \bold{\$6.3}[/tex]

An item is regularly priced at $58. It is now priced at a discount of 80% off the regular price
Answer: The discount price is $11.60. The discount is $46.40. (I didn't know which answer you wanted)
Step-by-step explanation: First, you need to find the discount. To do that, all you need to do is multiply 58 by 80/100 (this is still equal to 80%). You should get 46.40 (you might get 46.4 but it's the same thing), Then, subtract 46.40 form 58. You should get 11.60. So your final answer should be $11.60.
The absolute value function, f(x) = |x + 2| , is shown.
If the graph is reflected over the x-axis, what is the
domain of the function?
All real numbers
All real numbers greater than or equal to 0
All real numbers greater than or equal to -2
all real number is less than or equal to -2
Answer:
All real numbers
Step-by-step explanation:
Domain corresponds to values of x on the x-axis here in the graph we see that the graph of f(x) = |x + 2| exists on every value of x either positive or negative like a point as (1 , 3) , (-3 , 1) , (-2 , 0) so its domain is actually
-∞ < x < ∞
meaning that the graph exists from negative infinity to positive infinity on the x-axis which means All real numbers.

Tim incorrectly says
that the solution of the system of equations is
x= -9, y= -4.
System of equations:
6x - 2y = -6
11 = y - 5x
a. What is the correct solution?
b. What error might Tim have made?
Answer:
a)First, solve and regroup
11=y-5x
y=11+5x.
Plug in:
6x-2(5x+11)=-6
6x-10x-22=-6
-4x-22=-6.
-4x=16
x=-4.
Plug it:
y=11+5(-4)
y=11-20
y=-9.
x,y=-4,-9.
b) The error Tim made is that he confused the x and y.
The correct answer is -4,-9.
He said it was -9,-4.
Hope this helps plz hit the crown ;D
The correct solution is -4,-9 time might have changed x coordinate with y-coordinate
What is a linear equation?
A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
6x-2y = -6...1
11= y-5x...2
(a) Rearranging the 2 equation;
11=y-5x
y=11+5x.
substituting in first equation;
6x-2(5x+11)=-6
6x-10x-22=-6
-4x-22=-6.
-4x=16
x=-4.
Now putting the value of x in second equation;
y=11+5(-4)
y=11-20
y=-9.
x,y=-4,-9.
(b) The error Tim made is; he confused the x and y.
The correct answer will be -4,-9.

Answer:
(-7, 0) and (0, -7)Step-by-step explanation:
Draw the graph of x = - y - 7.
Convert to the slope-intercept form (y = mx + b):
x = -y - 7 add y to both sides
x + y = -7 subtract x from both sides
y = -x - 7
This is the straight line equation. We only need two points to plot the graph.
Choose any value of x, put to the equation and calculate the value of y.
for x = 0:
y = -0 - 7 = -7 → (0, -7)
for x = -7:
y = -(-7) - 7 = 7 - 7 = 0 → (-7, 0)

An observational study of suburban towns reveals that towns with more dedicated park land tend to have higher median home prices. A real estate agent suggests that a town’s crime rate is a more accurate predictor of median home price.
What is the confounding variable in this study?
the median home price
the crime rate
the distance from a large city
the median home size
Answer:
the median home size.
Step-by-step explanation:
In this scenario, the confounding variable would be the median home size. This is because this factor is both a cause and effect of the median home prices. A bigger house would obviously be worth more than a smaller house so the house size affects the prices of the homes in the market. At the same time, the median home sizes can also cause an increase or decrease in crime rates as criminals are more likely to target homes that seem as though they have more valuables inside.
Answer:
Crime rate

How many hours must you drive if you drive 643 miles at 65 mph on the interstate? Round to the nearest tenth hour
Answer:
9.9 hours, rounded to the nearest tenth hour.
Step-by-step explanation:
To calculate the time of travel, we must first divide the distance by the speed. Why, you ask? Because of this equation:
[tex]Speed\=\ \frac{distance}{time}[/tex]
Therefore, with a little bit of arrangement, we get:
[tex]Time\=\ \frac{distance}{speed}[/tex]
So, let's get on with it.
[tex]Time\=\ \frac{643 \ miles}{65 \ mph}[/tex]
[tex]Time\=\ 9.9 \ hours [/tex]
Finally, we have our answer: 9.9 hours, rounded to the nearest tenth.
