Answer:
8 posters
Explanation:
first you need to find how many he posted the first week. You do this by multiplying 72 by 1/3, or 72/3. That is 24. Then, you need to subtract that amount, 72-24 is 48. Then, you need to figure out how many he posted the second week. To do that, you need to figure out what 1/6 of 48 is first. So you would need to divide 48 by 6, which equals 8. So if John posted 5/6 of 48, you then need to multiply 8 by 5, equaling 40. If john posted 40 of his 48, then 48-40 is 8, meaning he has 8 posters to post.

what is linear equations ?In math, a linear equation one of that of the form y=mx+b. The slope is B, and the una is m. As y and x are variable, the previous statement is frequently referred to as a "system of equations with 2 variables." Bivariate linear equations are logistic equations with two or more variables. Formulas can be found in various locations, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When such an equation has had the structure y=mx+b, where m represents the slope and b its y-intercept, it is known to as being linear. A model formula is said to be cubic if its solution seems to have the form y=mx+b, wherein m stands for the gradient and b for the y-intercept.
3x + 4y = 38
x + y = 12 ( Multiply by -3)
Hence
3x + 4y = 38
-3x - 3y = -36
Add
y = 2
In the case where y = 2
x = 12 - y
x = 12 - 2

What is the range of a function g?
Answer:
A { y | y ∈ ℝ, y ≠ -4, -3 }
Step-by-step explanation:
You want to know the range of the function shown in the graph.
RangeThe range is the vertical extent of the graph, the set of possible function output values.
Here, the function approaches the horizontal asymptote y = -3, but never has that output value. The "hole" at (5, -4) means the function never has the output value -4, either.
The range is all real numbers (ℝ) except -4 and -3.
A certain forest covers an area of 2500km Suppose that each year this area decreases by 6.25% What will the area be after 15 years Use the calculator provided and round your answer to the nearest square kilometer.
After 15 years, the area of the forest will be approximately 1523.4 km
A percentage is a unit used to express a portion of a whole number as a fraction of 100.
In this scenario, we are know that the area of a forest decreases by 6.25% each year. This means that each year, the area of the forest will decrease by
=> 6.25/100 times its original size.
To find the area of the forest after 15 years, we need to calculate the total decrease in area over 15 years. We can do this by multiplying the original area of the forest by the percentage decrease each year, and then repeating this calculation 15 times.
Starting with the original area of 2500km, we can calculate the first year's decrease by multiplying
=> 2500 x 100/6.25 = 157.5 km.
To find the area after the first year, we subtract
=> 2500 km - 157.5 = 2342.5 km.
We can repeat this calculation for the next 14 years to find the total decrease in area over 15 years. We can also use the calculator provided to simplify the calculation.
To do this, we enter 2500, then press the multiply button, enter 0.0625, then press the equal button, then press the subtract button, and finally enter the result from the previous calculation until we reach the final answer.
This means that the total decrease in area over 15 years was approximately
=> 1523.4 km,
which is equal to 61% of the original area of the forest

A local restaurant charges $15 for a jumbo cheese pizza and $1.35 for each additional topping. Write an equation, in slope-intercept form, to represent the total cost, y, for x toppings on a jumbo pizza.
A local restaurant charges $15 for a jumbo cheese pizza and $1.35 for each additional topping.
the total cost, y, for x toppings on a jumbo pizza is represented in slope-intercept form, by the equation y = $1.35x + $15
The slope-intercept equation for the total cost, y, for x toppings on a large cheese pizza is y = mx + b, where m is the slope and b is the y-intercept.
First, we must determine the slope (m). The slope shows the $1.35 cost of each subsequent topping. So, m = $1.35.
The y-intercept must then be determined (b). The y-intercept shows the large cheese pizza's starting cost of $15. So, b = $15.
When we plug these values into the equation, we get:
y = $1.35x + $15

Answer: Let's denote the length of the candle on day 1 as L.
On day 2, the length of the candle is L/2, on day 3 it is L/2^2, on day 4 it is L/2^3 and on day 5 it is L/2^4.
So, on day 5, the length of the candle is L/2^4 = L/(222*2) = L/16.
Given that the length of the candle on day 1 is 18 inches, we have:
L = 18
And the length of the candle on day 5 is:
L/16 = 18/16 = 9/8
So, the length of the candle on day 5 is 9/8 inches.

a pyramid is 860 ft high (due to erosion, its current height is slightly less) and has a square base of side 7740 ft. find the work needed to build the pyramid if the density of the stone is estimated at 168 lb/ft .
The work needed to build the pyramid is calculated by multiplying the area of the base by the height and the density of the stone.
The work needed to build the pyramid can be calculated by using the formula Work = Area x Height x Density. The area of the base of the pyramid can be calculated by using the formula Area = Side^2, where Side is the length of the side of the square base. In this case, the side of the square base is 7740 ft. So, the area of the base is 7740^2 ft^2. The height of the pyramid is 860 ft (due to erosion, its current height is slightly less). The density of the stone is estimated at 168 lb/ft. So, the work needed to build the pyramid is calculated by multiplying the area of the base by the height and the density of the stone, like this: Work = 7740^2 ft^2 x 860 ft x 168 lb/ft = 9.76 x 10^9 lb-ft.

The fraction that satisfies the problem is 20/24.
Equivalent fractions are fractions that have the same value, but different numerators and denominators.
If the fraction is equivalent to 5/6, then the numerator and denominator of the fraction is a multiple of 5 and 6, respectively.

4, -2, and -5.
Step-by-step explanation:
All the real solutions of f(x) = 0 are 4, -2, and -5. We know y = f(x) and f(x) = 0. So, we can conclude that y = 0. When y = 0, it means there isn't a point that moves up or down the y axis (vertically). The point would only move horizontally. When looking at the points on the x-axis, we see 4, -2, and -5. Those are on the x-axis and haven't moved vertically. So, the coordinates for those points would be 4, 0, -2, 0, and -5, 0. Remember, y = 0, and 4, -2, and -5 all have a zero in the y value. Therefore, the answer is 4, -2, and -5.
