Step-by-step explanation:

Tristian and Barry both are correct as 9,32 is a rational and terminating decimal.

A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

A terminating decimal is a decimal number with a finite number of digits after the decimal point. The repeating decimal 5.6500000000... can be used to represent a terminating decimal like 5.65, however, when it is zero, the value is typically referred to as terminating.

A decimal number having a limited number of digits following the decimal point is referred to as a terminating decimal. Therefore, all decimal numbers that terminate are rational numbers.

Hence both are correct.

The characteristics of the parallelogram and star gives;

Parallelogram;

Rotational symmetry: Yes

Point symmetry: Yes

Star:

Rotational symmetry: Yes

Point symmetry: Yes

Rotational symmetry is one in which a shape assumes its original appearance after a rotation.

Point symmetry are the property of two points that are equidistant from and on opposite sides of the coordinate axis

The parallelogram has rotational symmetry of 180°

The parallelogram has point symmetry

Therefore;

Parallelogram:

Rotational symmetry; Yes

Point symmetry; Yes

The star has rotational symmetry of 360°/5 = 60°

Given that points on the star when rotated about its center can be made to match up with opposite side, it is said to have point symmetry.

Greg will pay $25.99 for one ink cartridge after the rebate.

As stated in the question, rebate is the refund that customer receives. It is part of the amount paid. So, it can be easily deducted from the total amount. To find the payment amount, we will simply subtract rebate amount from ink cartridge cost.

Keep the values in mentioned relation to find the payment amount to be given by Greg for one ink cartridge.

Payment = 35.99 - 10

Performing subtraction to find the payment amount to be given by Greg

Payment = 25.99

Hence, the payment of $25.99 will be done by Greg for one ink cartridge after the rebate.

a)The acceleration, in km/h², in the first 15 mins = 200  km/h².

b) The distance between the two cities = 125 km.

c) The average speed during 20 the journey =  62.5  km/hr.

For the given question;

Every horizontal block is 1/8 hour = 7.5 minutes long.

Each vertical block has a speed of 10 km/hr:

The table drawn as per the data given in the table:

Time                    Velocity  km/hr

0 Min  ( 0 hr)   --->         0

15 Min (1/4 hr)   -->       50

45 Min (3/4 hr)  -->      50

60 MIn  ( 1 hr)      -->    100

90 Min  ( 3/2 hr)   --->  100

120 Min ( 2hr)     --->    0

The formula for acceleration:

Part a: Acceleration = final velocity - initial velocity / final time - initial time

Acceleration in the first 15 minutes:  (1/4 hr)  =  (50 - 0)/(1/4 - 0)  

= 50/(1/4)

=200

Thus, acceleration in the first 15 minutes is 200 kmph.

Part b: Distance among two cities:

= (1/2)(0 + 50)(1/4 - 0)  + 50 * (3/4 - 1/4)  + (1/2)(50 + 100)(1 - 3/4)  + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)

=  25/4  + 25 + 75/4   + 50 + 25

= 125

The difference distance for two cities is 125 kilometers.

Part c: Average speed = distance/2

Average Travel Speed = 125/2 = 62.5 km/hr

Therefore,

a: Acceleration in the first 15 minutes = 200  km/h²

b: The distance between two cities is 125 kilometers.

c: The average speed of the journey is 62 miles per hour.

Converting the radicals into exponent numbers, √3 (⁴√3) = ⁴√27

To work with radical numbers or roots, it is easier to express them in exponent:

Recall the rules of exponent operations:

Note that the first 3 rules use the same base. If there are more than 1 base number, then group the exponent that have the same base first.

Example:

The angles which form a linear pair are 40° and 140°.

Linear pair is defined as the pair of angles which add up to 180 degrees.

When two straight lines intersect with one another then 4 angles are formed. Any two adjacent angles thus formed are a linear pair.

Let us consider one angle be x . Now another angle is 3.5 times this angle.

Therefore measure of second angle = 3.5x

Now if these two angles are a linear pair then their sum will be equal to 180°.

Therefore we can form a linear equation in x and solve to get the values of the angles.

∴3.5x + x = 180°

or, 4.5x = 180°

or, x = 180 ÷ 4.5

or, x = 40°

Measure of the second angle = 3.5 × 40° = 140°

Hence the two angles which form a linear pair are  40° and 140° .

The average rate of change of fuel efficiency = -3 gallon per hour

Fuel efficiency of the cooper when driving at a speed of 75 mph = 29 miles per gallon

Fuel efficiency of the cooper when driving at a speed of 60 mph = 34 miles per gallon

Let y₁ = 75 mph, y₂ = 60 mph

and x₁ = 29 miles/gallon , x₂ = 34 miles /gallon

Then the average rate of change of fuel efficiency = (y₂-y₁)/(x₂-x₁)

                                                        = (60 - 75)/(34-29)

                                                        = -3 gallon per hour
