N The distance between Tanjung Malim and Sungai Petani is x km. A car was driven from Tanjung Malim to Sungai Petani at an average speed of 90 km/h. The return journey when the car was driven at an average speed of 105 km/h took 30 minutes, Calculate the value of x CHAPTER SUMMARY​

Answers

Answer 1

Answer:

52.5 km

Step-by-step explanation:

the info about the trip from Malim to Petani is irrelevant and only there to confuse us.

but from the return trip info we get all we need.

for x km it took then 30 minutes at an average speed of 105 km/h.

to get km out of km/h, we need to multiply the speed number by the hours traveled. that removed the "h" and leaves us with km.

n km/h × a h = a×n km

so, now, in our example we have 105 km/h, and 30 minutes = 1/2 h.

so, we have

x = 105 km/h × 1/2 h = 105/2 km = 52.5 km

44 is the product 4 and Greg's height. Use the variable g to represent Greg's height

Answers

Step-by-step explanation:

do you happen to have a photo reference your sentence is a bit confusing

Answer:

44 = 4 · g OR g · 4 = 44

Step-by-step explanation:

So first we need to know what a variable is...

A variable is an unknown number in a math sentence

Knowing that we can write the equation.

"44 is the product 4 and Greg's height. Use the variable g to represent Greg's height"

Since we do not know Greg's height that is what we will use variable g to substitute it.

"44 is the product 4 and g"

Now all we have to do is convert this into an equation

(Note: Whenever you see product of something know that it means that you need to multiply)

So your final answer is...

44 = 4 · g

(Explanation: Since it says 44 is the product of then it means it is the answer so we will put an equal sign)

Janet has a $65 budget to buy paper goods and plastic cutlery for an impromptu birthday party. She determines that the paper goods will cost $37.50. How many sets

of cutlery can she purchase if each set costs $0.75?

Answers

You subtract the cost of the paper goods from the budget first 65-37.5, which equals 27.5, then you divide 27.5 by. 75, which equals 36.6 repeated, but you can't buy half a set of cutlery, so it's just 36.

Final answer 36.

Janet can purchase 36.67 sets of cutlery if each set costs $0.75.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

Janet has $65 to spend on paper goods and cutlery, and the paper goods will cost $37.50,

So, she has $65 - $37.50 = $27.50 remaining to spend on cutlery.

Each set of cutlery costs $0.75,

So, Janet can purchase sets of cutlery :

⇒ $27.50 / $0.75

Apply the division operation, and we get

⇒ 36.67

Since it's not possible to buy a fraction of a set, Janet can only buy 36 sets of cutlery.

Therefore, she can purchase 36.67 sets of cutlery.

I am the only toolkit function that has a start and end number for the range. I am also the only that is cyclic, meaning I repeat over and over.


Which toolkit function am I?

Answers

The Toolkit function that has a start and end number for the range and is also cyclic is ; The constant Function ( i.e. f(x) = a )

There are about (9) toolkit functions and some of these toolkit functions :

Constant function Cube root function Square root functionreciprocal squared functionreciprocal functioncubic and quadratic function Absolute value function

The common characteristics between the various toolkit functions is that they all have undefined domains ( i.e. ( - ∞ , ∞ ) or ( -∞, 0 ), and undefined ranges as well.  while the only Toolkit function with a defined range is the Constant function { a, a }

The range for a Constant function starts and ends with the value of the given constant. i.e. { a, a }. while other functions have undefined range values.

Hence we can conclude that the Toolkit function with a start and end number for the range is the Constant function.

construct a banner ?

Answers

Answer:

540 square feet worth of paper

Step-by-step explanation:

This is an area problem. Area is length multiplied by width. The provided length is 30 feet and the provided width is 18 feet. When they are multiplied, you get 540 square feet. Note that the height is the width in this context because if you laid the banner down, 18 would be the width. The banner is being held up, so the 18 feet is called the height.

Answers

Answer:

X equals 8.

Step-by-step explanation:

The polygon in the question has 5 sides. However, it is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides. So for a five sided polygon, the size of the exterior angle is calculated as

360/5 which equals 72. Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

Subtract 264 from both sides of the equation

12X = 96

Divide both sides of the equation by 12

X = 8

The value of x in the given polygon is 8.

What is Polygon?

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain

The polygon in  has 5 sides.

It is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides.

So for a five sided polygon, the size of the exterior angle is calculated as

360/5 =72.

Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

12X = 96

Divide both sides of the equation by 12

X = 8

let 1st angle be 4x and 2nd angle be 5x

4x + 5x = 90 [Complementary means the sum of angles is 90]
