Answer:

y = 1/3x - 7

Step-by-step explanation:

start with the point-slope form:

(y-y1) = m(x-x1)

substitute the values of (x,y) into the formula:

(y-(-5)) = 1/3(x-6)

y+5 = 1/3x - 2

now write in slope-intercept form:

y = 1/3x - 2 - 5

y = 1/3x - 7

As CD⊥AB, ∠BDC = ∠ADC = 90°

∠BDC ≅ ∠ADC

and

We can substitute ∠ADC with ∠BDC and ∠DAC with ∠DBC

Then we get same equation for ∠BCD and ∠ACD

Therefore ∠BCD = ∠ACD = 1/2∠ACB

It proves that CD bisects ∠ACB

There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.

To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.

Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.

Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.

To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.

Therefore, there will be 12 slices of pizza left over.

To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.

If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

The possible values for angles 1, 2, and 3 given that lines a and b are parallel lines include the following:

In Mathematics and Geometry, parallel lines are two (2) lines that are always the same (equal) distance apart and never meet or intersect.

Note: Assuming angle 1 is equal to 60 degrees.

In Mathematics and Geometry, the vertical angles theorem states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other:

m∠1 ≅ m∠3 = 60°.

Based on the linear pair postulate, the measure of angle 2 can be determined as follows;

m∠1 + m∠2 = 180°

60° + m∠2 = 180°

m∠2 = 180° - 60°

m∠2 = 120°

the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.

so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

The coordinates of the point 3/10 of the way from a to b is (-0.3, -6.3)

The given parameters are:

The position of the point is given as:

Location = 3/10

Express as ratio

m ; n = 3 : 10 - 3

This gives

m ; n = 3 : 7

The coordinates of the point are then calculated as:

Point = Location * (mx2 + nx1, my2 + ny1)

This gives

Point = 3/10 * (3 * 9 + 7 * -4, 3 * 7 + 7 *  -6)

Evaluate

Point = 3/10 * (-1, -21)

The volume of the container is approximately 12.9516 cubic meters when rounded to the nearest hundredth.

To find the volume of the container, we need to multiply its length, width, and height. Let's convert the given measurements to meters to ensure consistent units.

The length of the container is 2.76 meters.

The width of the container is 23.5 decimeters, which is equal to 2.35 meters (since 1 decimeter = 0.1 meters).

The height of the container is 196 centimeters, which is equal to 1.96 meters (since 1 meter = 100 centimeters).

Now we can calculate the volume of the container:

Volume = Length × Width × Height

Volume = 2.76 meters × 2.35 meters × 1.96 meters

Volume ≈ 12.9516 cubic meters (rounded to four decimal places)

Therefore, the volume of the container is approximately 12.9516 cubic meters when rounded to the nearest hundredth.

The possible grades for his final test in order to receive an A grade are 98, 99 and 100.

Average of a set of scores it the sum of the scores divided by the total numbers, The average score needed for an A grade should be greater than 93 but cannot exceed 100.

The inequality that represent the average score to have an A grade is 93 < x ≤ 100

Average = sum of scores / total number of tests taken

93 = (94 + 89 + 100 + 100 + 78 + x) / 6 9

93 = (461 + x) / 6

93 x 6 = 461 + x

Answer:

v = 339,3 in/sec

Step-by-step explanation:

The wheels are moving at a rate of 6 rps (revolutions per second), and the length of the wheel is (L) is

L = 2*π*r        where r is a radius of the wheel

L = 2*π*9   (in)

L = 56,55 ( in)

L will be the traveled length by car in each turn of the wheel

Since the wheel has a rate of 6 turns by second, then we need to multiply de numbers of turns by second  times, the traveled length in 1 turn, in order to get the speed of the car

Then:

v ( speed of the car ) is:

v = 6 * 56,55 ( in/sec)

v = 339,3 in/sec

Angular speed tails that how fast a object resolves.the car is moving with the velocity of 339.43 inches/second.

To find the angular speed of the wheel, we need to know about the angular speed.

Angular speed is the rate of change of angle with respect to time of an object. Angular speed tails that how fast a object resolves.

It can be given as,

\(\omega=\dfrac{v}{r}\)

Here,  is the \(v\) linear velocity and \(r\) is the radius.

Given information-

The radius of the wheels of the car is 9 inch.

The revolutions per second of the each wheel is 6 rpm.

As the wheel rotates at 6 revolutions per seconds. The one rev/sec equals to the \(2\pi\) rad.

Thus the angular velocity is,

\(w=2\pi N\)

\(\omega=2\pi \times 6\\\omega=12\pi\)

Put the values in the above formula,

\(\omega=\dfrac{v}{r}\\12\pi=\dfrac{v}{9}\\\)

Solve for \(v\)

\(v=9\times12\pi\\v=9\times12 \times\dfrac{22}{7} \\v=339.43\)

Hence the car is moving with 339.43 inches/second.

x    = 100

53 x 100 / 65 = 82 yellow fish

Green fish:
