After 4 hours of snow melting, there would be 8 inches of snow with the rate of 2.5 inches per hour Katherine would have on her lawn and after t hours the snow would be = 18 - 2.5*t inches.
In this question, the amount of snow melted is required to calculate to know the amount of snow on the lawn, can be calculated by:
the melted amount = rate of melting × timeGiven:
The total amount of snow = 18 inches
Rate of melting = 2.5 inches
Time = 4 hours
Solution:
The amount melted needs to be calculated first in order to find left snow, therefore, putting values in the formula mention above,
the melted amount = rate of melting × time
the melted amount = 2.5 × 4 inches
the melted amount = 10 inches
Then the final amount would have on the lawn = starting amount−melted snow
= 18−10 inches
= 8 inches
Part b) Snow after t hours:
Starting amount= 18 inches
Melted snow= inches per hour×t
= 2.5×t
= 2.5t
Final amount = starting amount−melted snow
= 18 -2.5t
Thus, the correct answer is - 8 inches and 18 -2.5t

14.) Is 136 divisible by 5? yes O
Answer:
The answer is no
Step-by-step explanation:
Is because if we divide 136 by 5 is gonna give us 27.2 and we don’t want the decimal. So we can’t divide 136 by 5. Another method is you can you at the last digit in this case is 6, six is not in the table of 5 so always the answer is going to be in decimal. 136[tex]:[/tex]5= 27.2

Step-by-step explanation:
breadth=x
length is 5m long then breadth
length=x+5
Perimeter=2(length+breadth)
subtitute values in formula:

solve: y=3x and x+y=20
Answer:
x = 5, y = 15
Step-by-step explanation:
Use substitution to solve the system of equations.
We'll replace y in x + y = 20 with 3x, since y = 3x.
x + 3x = 20
Combine like terms
4x = 20
Divide by 4 on both sides
x = 5
Now to solve for y (don't forget!)
We'll plug x = 5 back into one of the original equations
y = 3(5) = 15
Check first equation:
15 = 3(5)
15 = 15
Check second equation:
5 + 15 = 20
20 = 20

What's the password?" and, getting no answer from lonely foxes and whining cats, it had shud up its windows and drawn shades in an old maidenly preoccupation with self-protection which bordered on a mechanical paranoia. It quivered at each sound, the house did. If a sparrow brushed a window, the shade snapped up. The bird, startled, flew off! No, not even a bird must touch the house! The house was an altar with ten thousand attendants, big, small, servicing, attending, in choirs. But the gods had gone away, and the ritual of the religion continued senselessly, uselessly.

The greatest of four consecutive whole numbers, the smallest of which is b
Answer:
38
Step-by-step explanation:
Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108. Thus, 3x+6=108. Solving for x yields x=34. However, the question asks for the largest number, which is x+4 or 38. Please make sure to answer what the question asks for!
You could have also plugged in the answer choices. If you plugged in 38 as the largest number, then the previous even integer would be 36 and the next previous even integer 34. The sum of 34, 36, and 38 yields 108.

Russell decides to make a tile pattern after the first day his pattern has 8 tiles after the fourth day it has 35 tiles how many tiles was pattern have after the fifth day?
Answer:
44
Step-by-step explanation:
n = pattern number
9n - 1 = number of tiles
Number 5 = 9n - 1
= 5 x 9 - 1
= 45 - 1
= 44
The pattern will have 54 tiles after the fifth day
How to determine how many tiles was pattern have after the fifth dayTo determine the pattern, let's find the difference between the number of tiles on consecutive days:
Difference between Day 2 and Day 1: 8 tiles - 0 tiles = 8 tiles
Difference between Day 3 and Day 2: 20 tiles - 8 tiles = 12 tiles
Difference between Day 4 and Day 3: 35 tiles - 20 tiles = 15 tiles
Notice that the difference between the number of tiles on consecutive days is increasing by 4 each time (8, 12, 15).
Now, let's use this difference to find the number of tiles after the fifth day:
Difference between Day 5 and Day 4: 15 tiles + 4 tiles = 19 tiles
Number of tiles after the fourth day: 35 tiles
Number of tiles after the fifth day: 35 tiles + 19 tiles = 54 tiles
So, the pattern will have 54 tiles after the fifth day.

A quantity with an initial value of 850 grows continuously at a rate of 90% per
decade. What is the value of the quantity after 59 years, to the nearest hundredth?
Answer:
5400
Step-by-step explanation:
so 90% of 850 is 765 (0.90x850)
765 is 10 years
so 1 year is 765/10 = 76.5 per year. So 76.5x59 = 4,513.5 add the initial ammount and you got 5,363.5 in the nearest hundredth you get 5400

Including 8% sales tax, an inn charges $162 per night. Find
the inn's nightly cost before the tax is added.
Answer:
$150
Step-by-step explanation:
x + 0.08x = 162
1.08 x = 162
x = 150
The inn's nightly cost before the tax is added is $150.
Let's denote the inn's nightly cost before tax as "x." We are given that the inn charges $162 per night, including an 8% sales tax. This can be represented as an equation:
Total cost = Nightly cost before tax + Sales tax
$162 = x + 0.08x
Now, we can solve for "x":
$162 = 1.08x
x = $162 / 1.08
x = $150
So, the inn's nightly cost before the tax is added is $150.
We're asked to find the inn's nightly cost before the tax is added. Let's denote this cost as "x."
We are given that the total cost, including the 8% sales tax, is $162 per night. We can set up an equation using this information:
Total cost = Nightly cost before tax + Sales tax
Mathematically, this can be expressed as:
$162 = x + 0.08x
The 0.08x represents the 8% sales tax, which is 8% of the nightly cost before tax.
Now, we can combine the x terms on the right side of the equation:
$162 = 1.08x
To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 1.08:
x = $162 / 1.08
x = $150
So, the inn's nightly cost before the tax is added is $150. This means that if there were no sales tax, the inn would charge $150 per night. The 8% sales tax is then added to this base cost to reach the total of $162.

6x - 6 = 54
Step-by-step explanation:
The hypotenuse of both triangles are 63 and 6x - 6; the second longest sides are 49 (greater than 35) and 42 (greater than 30).
So our proportion:
63/(6x-6) = 49/42
Cross multiply
63*42 = 49*(6x-6)
2646 = 294x-294
2940 = 294x
x = 10
Double-check:
63/(6*10 - 6) = 49/42
63/(60 - 6) = 49/42
63/54 = 49/42
7/6 = 7/6
6x - 6 = 6(10) - 6 = 60 - 6 = 54
