Step-by-step explanation:

Sana makatulong

The dog eats 4.3 kilograms of dog food in a fortnight.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

A dog eats 150g of dog food twice a day.

A fortnight is “a period of two weeks,” that is, “fourteen days and nights.”

That means,

the dog eat in a fortnight,

= 150 x 14 x 2

= 4200 grams.

In kilograms,

the dog eats 4.3 kilograms of dog food.

Therefore, the dog eats 4.3 kilograms of dog food.

The parent function for this function represented in the table is an exponential function.

We have given that,

The function f is given by the table of values as shown below.

x     1   2    3    4     5

f(x)  9  11     15  23  39

An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula

f(x) = eˣ

11 - 9 = 2 = 2¹

15 - 11 = 4 = 2²

23 - 15 = 8 = 2³

39 - 23 = 16 = 2⁴

Therefore, we can deduce that the parent function for this function represented in the table is an exponential function.

If function f was translated up to 5 units, then f(x) values would be increased by 5. Also, a point in the table for the transformed function is equal to (1, 4).

[tex]K'M'P'T = \frac{3}{4}x[/tex]

Step-by-step explanation:

Given

Quadrilateral KMPT

[tex]k = \frac{3}{4}[/tex] ---- scale factor

[tex]KMPT = x[/tex] --- perimeter

Required: The perimeter of K′M′P′T′

To calculate the perimeter of K'M'P'T, we simply multiply the scale factor by the perimeter of KMPT

So:

[tex]K'M'P'T = k * KMPT[/tex]

[tex]K'M'P'T = \frac{3}{4} *x[/tex]

[tex]K'M'P'T = \frac{3}{4}x[/tex]

Answer:

See Explanation

Step-by-step explanation:

Note: This question is more of an opinion. The answers I will provide will be base on my personal encounters with the given quantities.

Solving (1): Estimates of the given quantities

To make estimates, you employ the use of measuring device of each quantity.

For instance:

Time ----- Clock

Angle ---- Protractor

Temperature ---- Thermometer

Rate ---- This solely depend on the rate that is being measured (e.g. speedometer for speed)

Solving (2): Estimate and Actual measurement

In my case, the answer is yes because I have mastered the use of each device.

Solving (3): Difficulties

Some of the difficulties that may be encountered when taking estimates are:

- Using the wrong tools

The absence of the right measuring devices or alternate devices will definitely not give an accurate result

(e.g it will be difficult to measure an angle with a ruler)

- Unstable environments

Stable environments give accurate results.

(e.g It may be difficult to measure the speed of a car when it does not move at a constant speed; In this case, you may opt for the instantaneous speed)

- Poorly calibrated or un-calibrated devices

When a device is not calibrated properly, the device will give wrong measurements.

Answer:

The spinner is not fair

Step-by-step explanation:

Given

[tex]Sections = 8[/tex]

[tex]Blue = 3[/tex]

[tex]Purple = 5[/tex]

Solving(a): Is it fair?

The spinner is not fair because the probability of an outcome of Blue does not equal the probability of obtaining Purple.

i.e.

[tex]P(Blue) = \frac{3}{8}[/tex]

[tex]P(Purple) = \frac{5}{8}[/tex]

[tex]\frac{3}{8} \ne \frac{5}{8}[/tex]

Solving (b):

To make it fair, the blue sections and the purple sections must be made equal (4 each)

I believe the answer would be 8 for line WE

For line QW the answer is 45 using the same method as the last quesiton

Step-by-step explanation:

This is because you would write

7x-13=15x-37

this would equal

x=3

Plug in the x value in line DW and FW and both equals 8

so logiically.I believe that line WE would equal 8.
