One wintry week a ski town got 15 1/2 inches of snow on Monday the town got 2 3/4 inches on Tuesday it got 1 1/2 times as much and on Wednesday it got 7/8 inches how much snow did the town get the rest of the week pls help I’ll give Brainlyleast (14 points)
Answer: On Monday the town got 2 3/4 (2.75) inches of snow.
On Tuesday it got 1 1/2 (1.5) times as much: 2.75 x 1.5 = 1.375 (inch)
⇒ On Tuesday the town got 1.375 inch of snow.
On Wednesday it got 7/8 (0.875) inch of snow.
After Monday, Tuesday and Wednesday, the town got:
2.75 + 1.375 + 0.875 = 5 (inches of snow)
For the rest of the week, the town got:
15 1/2 - 5 = 10 1/2 = 10.5 (inches of snow)
Step-by-step explanation: hope it helped :))
Answer:
7.76 inches, and this is NOT including Saturday and Sunday
Step-by-step explanation:
Monday: 2.75 inch
Tuesday: 2.75 * 1.5 = 4.12 inches
Wednesday: 7/8 = .87 inches
So, you add
2.75 + 4.12 + .87 = 7.74 inches for Mon, Tues and Wed.
then 15.50 - 7.74 = 7.76 inches of snow for both Thurs and Friday

minimum list price $ (10,800-14,000-11,600-6800)
minimum list price $ (18,800- 10,800-11,600-14,000)
9514 1404 393
Answer:
minimum $11,600maximum: $14,000Step-by-step explanation:
The graph shows price decreases with age, so the minimum price will be associated with cars that are 3 years old. We read from the graph that the price of a 3-year-old car is about $11,600. (This is slightly more than halfway between the $11,000 and $12,000 grid lines.)
The maximum will be associated with a 2-year-old car. We can read the graph to find the price of a 2-year-old car is $14,000. That value is on the grid line, so no guessing is necessary.
Then we have ...
minimum: $11,600
maximum: $14,000
_____
Additional comments
We'd like to check our guess of the minimum using the given price equation. Filling in x=3 in the equation, we get ...
2400·3 +6800 = 7200 +6800 = 14,000 . . . . matches the maximum, not the minimum
We observe that the equation has a positive coefficient for x, so will be the equation of a rising line, not the falling one shown on the graph.
For "fun", we can check to see what the equation gives for x=2:
2400·2 +6800 = 4800 +6800 = 11,600 . . . . matches the minimum, not the maximum
This gives us some confidence that our choice of numbers is correct, but makes it clear that the equation is incorrectly written.
The problem needs to be reported, so it can be fixed.

A contractor purchases 4 dozen pairs of padded work gloves for $56.16. She incorrectly calculates the unit price as $14.04 per pair for the expense report. What is the correct unit price? What is the error? Why is the contractor's unit price incorrect?
Answer:
The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.
Step-by-step explanation:
It is given 4 dozen pairs of gloves for $56.16.
So, unit price = Divide the price by number of pairs of gloves.
And 1 dozen =12
So 4 dozen =4*12=48 pairs of gloves
So, to find unit rate divide 56.16 by 48.
Unit price =[tex]\frac{56.16}{48}= $1.17[/tex]
So, the error is she didn't convert the dozen to units.
That made mistake in finding unit price.

x2 - 81
Trying to factor as a Difference of Squares:
1.1 Factoring: x2 - 81
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 81 is the square of 9
Check : x2 is the square of x1
Factorization is : (x + 9) • (x - 9)

Trying to factor by splitting the middle term
2.1 Factoring x2 - 18x + 81
The first term is, x2 its coefficient is 1 .
The middle term is, -18x its coefficient is -18 .
The last term, "the constant", is +81
Step-1 : Multiply the coefficient of the first term by the constant 1 • 81 = 81
Step-2 : Find two factors of 81 whose sum equals the coefficient of the middle term, which is -18 .
-81 + -1 = -82
-27 + -3 = -30
-9 + -9 = -18 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -9
x2 - 9x - 9x - 81
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-9)
Add up the last 2 terms, pulling out common factors :
9 • (x-9)
Step-5 : Add up the four terms of step 4 :
(x-9) • (x-9)
Which is the desired factorization

2.2 Factoring x2-6x-27
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -27
Step-1 : Multiply the coefficient of the first term by the constant 1 • -27 = -27
Step-2 : Find two factors of -27 whose sum equals the coefficient of the middle term, which is -6 .
-27 + 1 = -26
-9 + 3 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and 3

Step-4 : Add up the first 2 terms, pulling out like factors :

5 30
Write your answer as an equation with f(x) first, followed by an equals sign.
Answer:
The linear equation that gives the rule for this table will be:
y=x+25Step-by-step explanation:
Taking two points from the table
(2, 27)(3, 28)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:27\right),\:\left(x_2,\:y_2\right)=\left(3,\:28\right)[/tex]
[tex]m=\frac{28-27}{3-2}[/tex]
[tex]m=1[/tex]
We know the slope-intercept form of linear equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
substituting the point (2, 27) and m=1 in the slope-intercept form to determine the y-intercept 'b'
[tex]y=mx+b[/tex]
27 = 1(2)+b
27-2 = b
b = 25
Now, substituting m=1 and b=25 in the slope-intercept form to determine the linear equation
y=mx+b
y=1(x)+25
y=x+25
Thus, the linear equation that gives the rule for this table will be:
y=x+25The linear equation that gives the rule of the table is f(x) = x + 25
The linear equation can be represented in a slope intercept form as follows:
y = mx + b
where
m = slope
b = y-intercept
Therefore,
Using the table let get 2 points
(2, 27)(3, 28)
let find the slope
m = 28 - 27 / 3 -2 = 1
let's find b using (2, 27)
27 = 2 + b
b = 25
Therefore,
y = x + 25
f(x) = x + 25
