In the figure, ∆ABD ≅ ∆CBD by Angle-Side-Angle (ASA). Which segments are congruent by CPCTC?
Answer: AB ≅ CB
Step-by-step explanation:
In the given figure, we have ∆ABD ≅ ∆CBD
The CPCTC property of congruent triangles says that if two triangles are congruent then their corresponding parts ( angles and segments ) are congruent.
Since we have given that ∆ABD ≅ ∆CBD.
Therefore, the corresponding segments are congruent.
As segment AB is corresponding to segment CB. [First two letters]
Therefore, segment AB is congruent to segment CB.
Please help me find the mean and the median:
Answer:
anyways your answer is 1
Step-by-step explanation:
Use the information to answer the question.
A data set is normally distributed. The mean of the data is 9.2, and the standard deviation is 1.8.
Using the 68-95-99.7 rule, what percentage of the data points are greater than 11? Enter the answer in the box.
%
Using the Empirical Rule, it is found that 16% of the data points are greater than 11.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, the mean is of 9.8 and the standard deviation is of 1.8.
11 is one standard deviation above the mean. Considering the symmetry of the normal distribution, 32%(more than one standard deviation above the mean)/2 = 16% of the data points are greater than 11.

Find the volume of the fish tank and round to the nearest hundredth if necessary.
Answer:
The volume of the fish tank is 67.02
Step-by-step explanation:
To find the volume of a rectangular prism, multiply length times width times height.

A garden has the shape of a circular sector such that its straight sides measure 50 feet in length and the central angle is 132°. if the garden needs to be surrounded by fencing, how many feet are needed to enclose the garden?
Answer:
215 ft
Step-by-step explanation:
The length of the surrounding fence is equal to the perimeter of the garden. That is the sum of the lengths of the straight sides and the curved arc. The arc length is given by the formula ...
s = r·θ . . . . . where θ is the central angle in radians
__
arc lengthThere are π radians in 180°, so the arc will have a measure in radians of ...
θ = 132° × (π/180°) = 11/15π ≈ 2.3038 . . . . radians
Then the length of the curved side of the garden is ...
s = (50 ft)(2.3038 radian) ≈ 115.2 ft
__
perimeterThe fence length is the sum of the arc length and the two radii:
perimeter = 115.2 ft + 2×50 ft = 215.2 ft
About 215 feet of fencing are needed to enclose the garden.

Slope intercept form looks like so:-
y=mx+b
Right now the line's equation is written in standard form, ax+by=c.
First, subtract 12x on both sides:-
4y=-36-12x
Now divide by 4 on both sides:-
y=-9-3x
On further simplification,
switch -9 and -3x places (it's not mandatory)
y=-3x-9
That's our equation in slope intercept form.

The sum of two numbers is 24. Twice the first number plus the second is 26. Find the numbers.
Answer:
2 and 22
Step-by-step explanation:
You can put them into equations:
x+y=24 and 2x+y=26
Then, for each equation solve for one of the variables. It doesn't really matter which one but I chose y here.
y=24-x and y=26-2x
Since both equations are equal to y it means that the expression on the right sides of the equal sign are equal to each other:
24-x=26-2x
From here solve for x and you are left with:
x=2
Now that you know one variable go back and plug it into an equation and solve for y. Again, it doesn't matter which one you choose, you will end up with the same answer:
(2)+y=24
So..
y=22

Write a sine function that has an amplitude of 5, a midline of 2 and a period of 3/7
A sine wave is also known as a sinusoid. The sine function that has an amplitude of 5, a midline of 2 and a period of 3/7 is 5Sin(16πx/3)+2.
What is sine function?A sine wave, also known as a sinusoid, is the graph of the sine function. Any curve that can be expressed in the form is referred to as a sinusoid. (A and B are both positive.) Sinusoids are the most generic version of the sine function.
Given the amplitude of the function is 5, the vertical shift is 3, and the period of 3/7. Therefore, the values of constants can be written as,
a = 5
b = (2π)/(3/7) = 14π/3
d = 2
Substituting the values in the sine function,
a sin b (x-c) + d
= 5 Sin(16π/3)(x-0) + 2
= 5 Sin(16πx/3) + 2
Hence, the sine function that has an amplitude of 5, a midline of 2 and a period of 3/7 is 5Sin(16πx/3)+2.

John is traveling at 48 miles per hour and his distance can be written as d = 48t.
How far will John travel if he travels for 5 hours?
Answer:
240 miles
Step-by-step explanation:
To find how far John will travel is he travels 48 miles per hour for 5 hours, you can multiply John's speed (48 mph) with his travel time (5 hours) to get:
48 mph × 5 hours = ?
48 × 5 = 240
Therefore, John will travel 240 miles if he travels for 5 hours at 48 miles per hour.

Two metal disks, one with radius r = 2. 50 cm and the other with radius r = 5. 00 cm are welded together and
The total moment of inertia of the two disks will be I = 2.375 × 10-³ Kgm² welded together to form one unit.
What is moment of inertia?Moment of inertia is the quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation.
Using the formulas to calculate the moment of inertia of a solid cylinder:
I = ½MR²
Where;
I = moment (kgm²)
M = mass of object (Kg)
R = radius of object (m)
Total moment of inertia of the two disks is expressed as: I = I(1) + I(2)
That is;
I = ½M1R1 + ½M2R2
According to the provided information;
R1 = 2.50cm = 0.025m
M1 = 0.800kg
R2 = 5.00cm = 0.05m
M2 = 1.70kg
I = (½ × 0.800 × 0.025²) + (½ × 0.05² × 1.70)
I = (½ × 0.0005) + (½ × 0.00425)
I = (0.00025) + (0.002125)
I = 0.002375
I = 2.375 × 10-³ Kgm²
Hence The total moment of inertia of the two disks will be I = 2.375 × 10-³ Kgm² welded together to form one unit.
