On monday a farmer sold 25,196 pounds of potatoes on tuesday he sold 18,023 pounds. On wensday he sold some potatoes in all he sold 62,049 pounds of potatos
Given :
Total pounds of potatoes, T = 62,049.
On Monday a farmer sold 25,196 pounds of potatoes on Tuesday he sold 18,023 pounds.
To Find :
How many pounds he sold in Wednesday to end the stock.
Solution :
Potatoes sold in Wednesday = Total - Potatoes sold in Monday - Potatoes sold in Tuesday
= 62049 - 25196 - 18023 pounds
= 18830 pounds
Hence, this is the required solution.

13 of the 18 players on the varsity soccer team are seniors. What percent of the players on the team are not seniors?
Answer:
27.7778
Step-by-step explanation:
If 13 out of 18 players are seniors then 5 of them are not.
To find the percentage you do (5/18) ⋅ 100
5 divided by 18 gives us 0.27777778
Then we multiply by 100 (or move the decimal point two spaces to the right)
The result should be 27.7778%
(the 7s go on forever)

A family is taking a car for a road trip. The distance traveled is represented by y=55x. The distance in miles y and gallons used by the car is x.
Part 1. If the car has gone 385 miles, how much gas was used?
Part 2. The inverse function for this situation is the gallons of gas as a function of distance in miles. Write this equation.
Answer:
y=55x
given y=385
x=gallons of gas = 385/55 = 7 gallons
inverse function
y=55x
change x to y and y to x
x=55y
y=x/55
inverse function is x/55

Answer:
y - 3 = (1/2)(x - 4)
Step-by-step explanation:
The graph is hard to read, but we can make assumptions about the x- and y-values shown. The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3). Let's try finding the equation of the line using this assumed data:
The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
We need the slope of the line. Recall that m = rise/run. Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2. Thus, the slope is m = rise/run = 2/4, or 1/2.
Substituting the known values into the point-slope equation y - k = m(x - h), we get:
y - 3 = (1/2)(x - 4)

What would an equation be for a line with a slope of 3 and a y-intercept of 7?
Answer:
y = 3x + 7
Step-by-step explanation:
Using the formula y = mx + b we can create this equation.
m = slope
b = y -intercept
based on the information provided I know that
Slope = 3
and
y-intercept = 7
Substitute:
y = mx + b
y = 3x + 7
y = 3x + 7 is the equation when the slope is 3 and the y intercept is 7.
Let us use the slope-intercept form for this, with m as the slope and b as a constant.
y = mx + b
7 = 3(0) + b [since the y-int is 7, the x value will be zero]
b = 7
y = 3x + 7

HELP PLEASE! I will rate 5 stars and give brainliest!!!
Answer:
see explanation
Step-by-step explanation:
The n th term ( explicit formula ) of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁₂ = - 95 and a₃₇ = - 270 , then
a₁ + 11d = - 95 → (1)
a₁ + 36d = - 270 → (2)
Subtract (1) from (2) term by term to eliminate a₁
25d = - 175 ( divide both sides by 25 )
d = - 7
Substitute d = - 7 into (1) and solve for a₁
a₁ + 11(- 7) = - 95
a₁ - 77 = - 95 ( add 77 to both sides )
a₁ = - 18 , thus
[tex]a_{n}[/tex] = - 18 - 7(n - 1) = - 18 - 7n + 7 = - 7n - 11
[tex]a_{n}[/tex] = - 7n - 11 ← explicit formula
--------------------------------------------------------------
The recursive formula allows a term in the sequence to be found by adding the common difference d to the previous term, thus
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 7 with a₁ = - 18 ← recursive formula
What is the inverse of the function f(x) = 4x + 8?
O h(x) = 1/4x-2
O h(x) = 1/4x+2
O h(x) = 1/2x-2
O h(x) = 1/2x+2
[tex]f(x)=4x+8\\y=4x+8\\x=4y+8\\\\[/tex]
Proceed the inverse. Swap the x and y.
[tex]x-8=4y\\\frac{x}{4}-\frac{8}{4}=y\\y=h(x)\\h(x)=\frac{x}{4}-2\\h(x)=\frac{1}{4}x-2[/tex]
So the answer is first one.

Hope this helps :3
if it did pls mark brainliest
Answer:
A & E
Step-by-step explanation:
First, multiply 40 by 100, giving you 4000. You then divide 4000 by 25, where you will get a quotient of 160. Now, this can be represented as 160% or 160/100 because a percentage is always out of 100.
Mark gather data about the number of pink and red flowers that bloom down several of his flowering shrubs the scatterplot shows did he gathered and line of best fit equation of the line of best fit is y=1.73x + 0.0924 Based on the line of best fit approximately how many pink flowers are predicted to bloom on a shrub with 40 red flowers
Answer:
im pretty sure its 69 cause if u look its halfway between 33 and 33x2 is 66 and 69 is ther closest to that
Step-by-step explanation:
From the line of best fit, the pink flowers that would bloom on a shrub with 40 flowers = 69.29
How to solve for the pink flowers using the line of best fit.
The equation of the regression line = y=1.73x + 0.0924
We have x = 40
We have to put the value of x in the equation
y=1.73*40 + 0.0924
= 69.29
Therefore the line of best fit that would bloom on a shrub with 40 red flowers is 69.29
