The numbers 7, 22, 11, 34, 17, 52, 26, 13 and so on represent hailstone sequence.

These patterns are referred to as hailstone sequences because the values frequently rise and fall, resembling a hailstone inside a cloud.

It should be noted that such numbers can either rise or fall.

The speed of the car at the bottom of the loop is approximately 31.3 m/s

The given parameters are;

Mass of the car = 500 kg

Radius of the loop = 20 meters

Velocity of the car at the top of the loop = 14 m/s

The kinetic energy at the top of the loop is therefore;

K E. = 0.5×500×14² = 49,000

The potential energy gained = 500×9.81×40 = 196200

Total energy = 49,000 + 196,200 = 245,200

The velocity at the bottom is therefore;

0.5×500×v² = 245,200

v² = 245,200 ÷ (0.5×500) = 980.8

v = √(980.8) ≈ 31.3

The correct solution of division fractions is 18/4.

Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. The primary objective of division is to count the number of equal groups that are created or the number of individuals in each group after a fair distribution.

When describing how much of anything is left over, a fraction is used. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator

Given that,

The division fraction is 6× 3/4

So, the fraction is 6/1×3/4

Therefore, the division fraction is  4×2/4 or 18/4

The reasonable domain of the given situation is 0≤ x ≤2 that is 0 to 2 hours.

We see that x is represented as the number of phone hours used, therefore it has to be a number larger or equal to zero, but not a negative number. So, on one end we have that the number of phone hours used (x) must be larger or equal to zero. On the other hand, when the battery goes to zero, there are no more phone hours to use. We can find what is that other limit by making the battery percent (y variable) equal to zero, and solve the equation for x, thus giving us the upper limit of usable phone hours:

=> y = 0 = 100 - 50x

=> 100 = 50x

=> x = 100/50

=> x = 2

Therefore, the phone can be used for a maximum of 2 hours and the situation may be written as 0≤ x ≤2.

the balance in the account at the 10th day will be equal to - $ 57.5.

Late fee for 1 day = $ 5.75

Number of days = 10

We will calculate the late fees for 10 days by using the operation of multiplication.

So, late fee will be:

Late fees = 10 × $ 5.75

Late fees = $ 57.5

Balance in the account at the 10th day = 0 - Late fees

Balance in the account at the 10th day = 0 - $ 57.5

Balance in the account at the 10th day = - $ 57.5

Answer:

  95°

Step-by-step explanation:

You want the measure of angle TVZ, when adjacent angle (2x+5)° and its supplement (2x+15)° are given. The larger of these is a vertical angle with respect to TVZ.

The angles marked (2x+15)° and (2x+5)° are a linear pair, hence supplementary.

  ((2x+15)° +(2x+5)° = 180°

  4x +20 = 180 . . . . simplify

  x +5 = 45 . . . . . . . divide by 4

  x = 40 . . . . . subtract 5

Angle TVZ is a vertical angle with respect to the one marked (2x+15)°, so has the same measure:

  ∠TVZ = (2(40)+15)°

  ∠TVZ = 95°

__

Alternate solution

The two angles RVW (2x+15)° and ZVW (2x+5)° obviously differ by 10°. They are a linear pair, so their sum is 180°. Finding these angles is then a "sum and difference" problem. The larger of the solutions is the one we want, as (2x+15)° is a vertical angle to TVZ. We know the larger of the solutions to the sum and difference problem will be (180° +10°)/2 = 95°, the measure of TVZ.

More about sum and difference problems:

When a+b = s, and a-b = d, the larger value (a) can be found by adding these equations: (a+b) +(a-b) = s+d, or 2a = s+d, or a = (s+d)/2. This is the expression we used above to find the larger of the two angles. (You notice it is not necessary to solve for x.)

Step 1: We must locate the slope, by using the slope formula, which is:

[tex]\frac{y2-y1}{x2-x1}[/tex]

When we plug it in we get:

[tex]\frac{-2-10}{9-3}[/tex]

Which simplifies to a -2

Step 2: We must plug in our values in the point-slope formula which is:

[tex]y-y1=m(x-x1)[/tex]

We can plug in (3,10) or (9,-2). It doesn't matter which one, we'll end up with the same answer. For this example, we'll use (3,10)

Marvin Co. sells a total of 12 flashlights and 84 pens

Price of pen sold by Marvin Co. = $6

Price of flashlight sold by Marvin Co. = $10

Total sales = $624

Let the number of flashlights be x and the number of pens be y

Formulating the equations:

10x + 6y = 624

It is given that customer bought 7 times as many pens as flashlights, therefore:

y = 7x

Putting y = 7x in the equation we get,

10x + 6(7x) = 624

10x + 42x = 624

52x = 624

x = 12

So, the number of flashlights sold is 12 and the number of pens sold is 84

A strategy for teaching division is by repeated subtraction. It involves repeatedly subtracting the same integer from a big number until the result is zero. It is a fantastic approach to teach kids about division. A technique called repeated subtraction, commonly referred to as division, removes an equal amount of items from a group.

Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

Given that,

The difference between 4 and the sum of a number and is equal to twice that number.

Repeated subtraction is a method for teaching division. Until the result is zero, the same integer must be repeatedly subtracted from a large number. Repeated subtraction, sometimes known as division, is a method that takes an equal number of elements out of a group.

Division's opposite is multiplication. If 3 groups of 4 total up to 12, then 4 are in each group when 12 is divided into 3 equal groups. The fundamental goal of division is to produce equal groups or to determine how many individuals are in each group following a fair distribution.

x×4+4=2x-4

Subtracting 4 on both sides

4x+4-4=2x-4-4

4x=2x-8

Now, substracting 2x from both sides

4x-2x=2x-8-2x

2x=-8

The range of values for the expressions are given by these following compound inequalities:

A compound inequality is a combination of multiple inequalities, at least two, involving operations such as and and or, explained below.

Hence one example of a compound inequality is:

a ≤ x ≤ b.

Which is read as follows:

x is greater or equal than a and less or equal than b.

The smallest possible value is when both a and b are at their lower bounds, hence:

a + b = 2 + 1 = 3.

The greatest possible value is when both a and b are at their upper bounds, hence:

5 + 2 = 7.

Then the range is:

3 < a + b < 7.

Since the ranges of a and b are open intervals, the ranges of the operations will also be composed by open intervals.

The smallest possible value is when both a and b are at their lower bounds, hence:

a x b = 2 x 1 = 2.

The greatest possible value is when both a and b are at their upper bounds, hence:

a x b = 5 x 2 = 10

Then the range is:

2 < ab < 10.

The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:

2 - 2 = 0

The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:

5 - 1 = 4.

Hence the range is:

0 < a - b < 4.

The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:

2/2 = 1.

The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:

5/1 = 5.

Hence the range is:

1 < a/b < 5.
