The speed of the bus is 125 kmph

What is speed?

Speed is a scalar quantity that refers to how fast an object is moving.

Given that, a speed of a bus that travels 250 km in 2 hours.

We know,

Speed = distance / time

Distance = 250 km

Time = 2 hours

Speed = 250 / 2

= 125 kmph

Hence, the speed of the bus is 125 kmph

Answer:

the standard form of a quadratic equation is ax² + bx + c

the vertex form is a(x - h) + k where h & k are the x and y coordinates

to get from standard form to vertex form, you would have to follow this formula to find h:

-b/2a

plug in the values, and you will get the value of h.

to get k, you plug in the value you have just found in the above formula into the original equation, and that is the value of k.

the a in the vertex form is the value of a in the standard form

so an example of this would be: x² + 2x + 4 where a = 1, b = 2 c = 4

to get this into vertex form we will use the formula -b/2a and solve:

-2/2(1) --> -2/2 = -1

now we plug in the value we found into the original equation wherever x is

(-1)² + 2(-1) + 4 --> 1 - 2 + 4 = 3

we have both h and k, and we will put this into vertex form:

a(x - h)² + k turns into ---> (x + 1)² + 3

why x+1 and not x-1? the original equation has a negative sign, and the result we have is negative. this conflicts with the original equation and is therefore turned into a positive 1

where did a go? since a = 1, we do not need to write it, if a was equal to 2 then we would write the 2 in front

The area of the rectangle is equal to the number of squares in the rectangle. Therefore, the area of the rectangle is 11 x 24 = 264.

How do we calculate?

To draw an area model to multiply 1.1 x 2.4, we can use a rectangle with a width of 1.1 and a height of 2.4.

The area of the rectangle is equal to the product of its width and height. The area of the rectangle is 1.1 x 2.4 = 2.64.

We have a grid with squares that are 0.1 units wide and 0.1 units high. If we place 11 squares side-by-side to form a row, and then place 24 rows of squares on top of each other, we will create a rectangle with an area of 1.1 x 2.4.

Final answer:

To draw an area model to multiply 1.1 x 2.4, create a rectangle divided into two parts representing the numbers and calculate the areas separately.

Explanation:

To draw an area model to multiply 1.1 x 2.4, you can create a rectangle divided into two parts. The length of one part represents 1.1 and the length of the other part represents 2.4. Then, calculate the area of each part separately by multiplying the length and width. Finally, find the sum of the two areas to get the product.

39!      

Explanation:

70% of 130 is 91  

70 x 130/

100

= 91 you do 70 time 130 divided by 100 which gets you to 91 so that means 91 patience have the flu to find how many don't have the flu you subtract 130-91 that gives you 39!

To convert temperatures in degrees Fahrenheit to Celsius, subtract 32 and multiply by .5556 (or 5/9).

5F= -15C

39F= 3.9C

Here's how you can convert Fahrenheit to Celsius:

1. First, we need to subtract 32 from the Fahrenheit temperature.

For 5F, we would do 5 - 32 to get -27.
For 39F, we would do 39 - 32 to get 7.

2. The next step in our conversion process is to multiply the result by 5/9.

For -27, we would do (-27 * 5/9) to get -15.
For 7, we would do (7 * 5/9) to get approximately 3.888888888889, but we want our result rounded to the nearest tenth of a degree. Thus, we round this value to 3.9.

So, to convert 5F to Celsius you get -15C and to convert 39F to Celsius you get 3.9C.
