The percent decrease in the travel time after getting a new job is 36%.
Percentage is defined as part of a whole expressed in hundredths or out of 100. It is usually written with the symbol "%".
First, determine the decrease in travel time after getting a new job by subtracting the new travel time of 30.72 minutes from the initial travel time of 48 minutes.
decrease in time = 48 - 30.72
decrease in time = 17.28
Then, determine the percent decrease by dividing the decrease in time of 17.28 minutes by the initial travel time of 48 minutes and multiply by 100.
percent decrease = (17.28 / 48) x 100
percent decrease = 36%

Some doctors recommend that men drink 3 liters of water every day. there are approximately 29.6 milliliters in 1 fluid ounce. which measurement is closest to the number of fluid ounces in 3 liters? responses 89 fl oz 89 fl oz 10 fl oz 10 fl oz 101 fl oz 101 fl oz 33 fl oz 33 fl oz
The measurement closest to the number of fluid ounces there are in 3 liters is 101 fl oz.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
If there are approximately 29.6 milliliters in 1 fluid ounce, then divide 3 liters by 29.6 milliliters to get the amount of fluid ounces it has.
29.6 milliliters = 1 fluid ounce
3 liters = 3000 milliliters
3000 milliliters / 29.6 milliliters = 101 fluid ounce
Hence, 3 liters ≈ 101 fluid ounces.

Write and solve and equation for each scenario. Use x for the variable in your equation. Show your work by first writing an equation and then solving it. Put the solution of your equation in the answer box. If you multiply a number (x) by 5, the product is equal to the sum of 20 and 15.
Based on the calculations, the unknown number (x) is equal to 7.
How to determine the unknown number?In order to solve this word problem, we would assign a variable to the unknown number, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the unknown number. Therefore, translating the word problem into an algebraic equation, we have the following;
Multiply a number (x) by 5 = 5x
The product is equal to the sum of 20 and 15 = 20 + 15 = 35.
Combining the above information, we have:
5x = 20 + 15
5x = 35
Dividing both sides by 5, we have:
x = 35/5
x = 7.

Step-by-step explanation:
15t + 30 = 20t | -15t
30 = 5t
t = 30/5 = 6
20 + 5t = -6t + 86 | + 6t
20 + 11t = 86 | -20
11t = 66
t = 6
18t + 20 = 24t + 50 | -18t
20 = 6t + 50 | -50
-30 = 6t
t = -30/6 = -5
18t - 2 = 10t + 54 | -10t
8t - 2 = 54 | +2
8t = 56
t = 56/8 = 7
7t - 5 = 15t + 91 | -7t
-5 = 8t + 91 | -91
-96 = 8t
t = -96/8 = -12

One type of plant root splits 4 times while growing in the ground. The number of new roots after each split can be modeled by the function f(x)=3x, where x is the number of times the root splits. What is the domain of f(x)? CLEAR CHECK All positive integers All positive integers less than or equal to 4 All integers All positive integers greater than or equal to 4
The domain of the function f(x) = 3x is (b) All positive integers less than or equal to 4
How to determine the domain of the function?From the question, we have the following equation of the function that can be used in our computation:
f(x) = 3x
In this case, the notations are given as
x = Number of splits
f(x) = number of new roots in each split
From the question, we have
Splits = 4
This means that the maximum value of x is 4
The other values of x would be
x = 1, 2, 3, 4
This can be represented as
0 ≤ x ≤ 4
The interpretation of the above notation is all positive values less than or equal to 4
Hence, the domain value is option (b)

a circular curve is to be constructed with a 225 ft radius and an interior angle of 55 degrees. the separation between the stakes along the arc is 50 ft. assuming the curve is laid out from point to point, what is the last deflection angle?
The curve is laid out from point to point, the last deflection angle of circular curve is 26.5°
In the given question we have,
Radius of circular curve (R) = 225 ft
intersection or central angle in circular curve (I or delta) = 55°
separtion between stakes alaong arc = 50 ft
Angle of deflection is measured from tangent at PC or PT to any point .
deflection angle formula
deflection angle = (Lc /L)(I/2)
where, Lc is long chord and L is lenth of arc , I is central angle
first we find out the value of Lc and L
using formula , R = Lc / 2sin(I/2)
Lc = 225× 2 sin(55°/2) = 208 ft
L = R × I ×π/180°
L = 225 × 3.14 ×55/180 = 215.8 ~ 216 ft
put all the vales in deflection angle formula we get ,

Explanation:
x = number of weeks
y = height of the plant (inches)
The first sentence of "plant is 4 inches tall on week 8" gives us the point (x,y) = (8,4)
The second sentence gives us the point (32,16)
To find the growth rate, compute the slope.
[tex](x_1,y_1) = (8,4) \text{ and } (x_2,y_2) = (32,16)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{16 - 4}{32 - 8}\\\\m = \frac{12}{24}\\\\m = \frac{1}{2}\\\\m = 0.5\\\\[/tex]
The slope of 0.5 means the plant grows 0.5 inches per week.
Put another way, the plant grows 1 inch per every 2 weeks.
-----------------
Another approach:
The plant goes from 4 inches to 16 inches. It has grown 16-4 = 12 inches over the timespan of 24 weeks (since 32-8 = 24).
So its growth rate is 12/24 = 0.5 inches per week.
Notice how these values and calculations were mentioned in the previous section.

Essentially, the formula calculating area is equivalent to the product of the rectangle's length and breadth.For the given question.
David's kitchen is 60 square feet in size. The kitchen is six times the size of the living room.Thus,
Area of kitchen = 6 x area of the pantry
60 = 6 x area of the pantry
area of the pantry = 60 / 6 = 10 square feet.
Area of the pantry = length x breadth

2(-x - 5) = 12
2(-x - 5) = 12
Step 1 : Expand the bracket.
=> -2x - 10 = 12
Step 2 :Add both side by 10.
=> -2x - 10 + 10 = 12 + 10
=> -2x = 22
Step 3 : Divide both side by -2.
=> -2x : (-2) = 22 : (-2)
=> x = -11
Therefore, x = -11.
Answer:
x = - 11
Step-by-step explanation:
2(- x - 5) = 12 ( divide both sides by 2 )
- x - 5 = 6 ( add 5 to both sides )
- x = 11 ( multiply both sides by - 1 )
x = - 11
