Answer:
159 minutes
Step-by-step explanation:
y = .11x + 3
$3 initial fee to start the scooter
$0.11 per minute
y = the total bill price of the scooter ride
x = the total minutes of the ride
plug in what we know : $20.49 for the whole ride
20.49 = 0.11x + 3
SOLVE !! 20.49 - 3 = 0.11x
17.49 = 0.11x
17.49 / 0.11 = x
x = 159 minutes
check answer if you want
20.49 = 0.11 (159) + 3
20.49 = 17.49 + 3
20.49 = 20.49

The smallest camera in world is 0.99 millimeters in diameters is the diameter less than or greater than 0.1
99 is bigger than 10 therefore stating the video camera has a greater diameter than .1 .
What is an example of diameter?
If you look at the cycle wheel, the spikes that run through the center from one end to the other are an illustration of diameter. This is comparable to a circle's diameter, which is a line segment that extends from one end of the circle to the other end while passing through the center.The diameter of this camera is greater than .1 millimeter because On a ruler, .99 millimeter is farther to the right than .10 millimeters.
Also, and easier way to look at this is taking away the decimal.

Three personal watercraft vehicles launch from the same dock. The first vehicle leaves the dock traveling due northeast, while the second vehicle travels due northwest. Meanwhile, the third vehicle leaves the dock traveling due north.
The first and second vehicles stop about 300 yards from the dock, while the third stops about 212 yards from the dock.
(b) Write a coordinate proof to prove that the dock, the first vehicle, and the second vehicle form an isosceles right triangle.
The first and second vehicle form ΔAOC and ΔBOC are congruent so they will be an isosceles triangle.
How to plot a graph?A graph is a visual representation of how one variable changes over time in connection to one or more other variables.
We must determine the values of y that correlate to the value of x in order to plot the graph.
The coordinate geometry must then be changed to reflect the values of x and y.
Given the condition making a graph as shown below,
Now in ΔAOC and ΔBOC, the angle x is the same.
Distance AO = BO and CO is common side.
So both triangles will be congruent.
All congruent triangles will be isosceles triangles since all sides are equal which means two sides will be equal.
Hence "The first and second vehicle form ΔAOC and ΔBOC are congruent so they will be an isosceles triangle.".

Step-by-step explanation:
out of the 3 values, there is for every line one missing. so, we need to use the formula that calculates the missing value out of the other 2.
and based on the density value (in most cases already given in the table) we mark float or sink (as your paper says, if it is smaller than 1g/cm³, it will float, if it is larger, it will sink).
1.
density is missing
D = M/V = 12/0.5 = 12/0.5 × 2/2 = 24/1 = 24 g/cm³

4.
volume is missing.
V = M/D = 0.9/0.3 = 3 cm³
floats
5.
density is missing
D = M/V = 6/4 = 3/2 × 0.5/0.5 = 1.5/1 = 1.5 g/cm³

A board must be cut so that its length is 40.50 cm. The tolerance is 0.25 cm . Which inequality describes the allowable lengths for the board?
(A) |x-0.25| ≤ 40.50
(C) |x-40.50| ≤ 0.25
(B) |x+0.25| ≤ 40.50
(D) |x-0.25| ≤ 40.75
The inequality that describes the allowable lengths for the board is |x - 40.50| ≤ 0.25
How to determine which inequality describes the allowable lengths for the board?The given parameters are
Length = 40.50 cm
Tolerance = 0.25 cm
The inequality that describes the allowable lengths for the board is represented as:
|x - Length| ≤ Tolerance
This gives
|x - 40.50| ≤ 0.25
Hence, the inequality that describes the allowable lengths for the board is |x - 40.50| ≤ 0.25

This is $200 higher than the fine in Denver.
How much is the fine in Denver? Use x as your variable.
The cost of the fine in Denver is $100.
How much is the fine in Denver?The mathematical operation that would be used to determine the cost of the fine in Denver is subtraction. Subtraction is the mathematical operation that is used to determine the difference between two or more numbers. The sign used to denote subtraction is - . Other mathematical operations are addition, division and multiplication.
In order to determine the cost of the fine in Denver, subtract $200 from the cost of the fine in Colorado Springs.
The equation that represents the cost of the fine in Denver is:
Cost of the fine in Colorado Springs = $200 + cost of the fine in Denver
$350 = $200 + x
In order to determine the value of x, subtract $200 from both sides of the equation.

Answer:

Step-by-step explanation:
A shipping container will be used to transport several 130-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 26500
kilograms. Other shipments weighing 7700 kilograms have already been loaded into
the container. What is the greatest number of 130-kilogram crates that can be loaded
into the shipping container?
The maximum number of 130 kg crates that can be loaded into the shipping container is 137 which is calculated using linear inequality.
A linear inequality in mathematics is an inequality involving a linear function. One of the symbols for inequality is found in a linear inequality. It displays non-equal data in graph style.
An example of linear inequality is : 2x+8>18
Linear inequality can be represented using several symbols such as:
<,>,≥ and ≤.
Let us consider there are x number 130 kg crates.
The shipping container can take a maximum weight of 26500 Kilogram.
There is already 7700 kilograms of shipment loaded
Therefore we can write an linear inequality in x such as:
130x+7700 ≤ 256500
Subtracting 7700 from both sides we get:
130x+7700-7700 ≤ 25600-7700
or,130x ≤ 17900
Dividing both sides by 130
or, x ≤ 137.69....
Now we can say as the crates must be whole therefore the maximum number of 130 kg crates that the shipping container can hold is 137.

The simplified form of expression is -5/7.
To simplify the expression, we will solve the equation to convert them in smallest divisible fraction.
For this, firstly solving the numerator of fraction and then solving the denominator of fraction.
Solving numerator -
Numerator = -11 -4
We will perform addition along with keeping the answer with negative sign
Numerator = -15
Solving denominator -
Denominator = 12 - (-9)
Here two negative signs are present, so we will perform addition. Also, the sign of result will also be positive
Denominator = 12 + 9

Since angle ABC (m∠ABC) is bisected by line BD, the measure of m∠DBC is equal to 44°.
What is a line segment?A line segment can be defined as the part of a line in a geometric figure such as a triangle, quadrilateral, rhombus, parallelogram, circle, etc., that is bounded by two (2) distinct points and it typically has a fixed length.
What is a perpendicular bisector?A perpendicular bisector can be defined as a type of line that bisects (divides) a line segment exactly into two (2) halves and forms an angle of 90 degrees at the point of intersection.
Since angle ABC is bisected by line BD, we have:
m∠ABD = m∠DBC = m∠ABC/2
m∠ABC/2 = 8x/2 = 4x
Substituting the given parameters into the expression, we have;
m∠ABD = m∠DBC = 4x
2x + 22 = 4x
4x - 2x = 22
2x = 22
x = 22/2
x = 11
Now, we can find m∠DBC as follows:

Explicit expressions help represent all members of a sequence in one expression. The explicit formula for an arithmetic sequence is an = a + (n - 1)d, and each term in the sequence can be computed without knowing the other terms in the sequence.
In general, an explicit formula is the nth term of arithmetic, geometric, or harmonic sequence.
Explicit expressions are always used to represent any term in a sequence without describing any other term in the sequence. The meaning of "explicit" is direct, which can be found directly without knowing the other terms in the sequence.
