The average speed in km per hour is 40 km/hour if a motorist travels 100km in 2 1/2 hours the answer is 40 km/hour.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

The complete question is:

If a motorist travels 100km in 2 1/2 hours, what is his average speed in

km per hour?​

We have:

The distance; a motorist travels  = 100 km

The time he takes = 2 1/2 hours

or

The time he takes = 5/2 hours

or

The time he takes = 2.5 hours

The average speed in km per hour = distance/time

The average speed in km per hour = 100/2.5

The average speed in km per hour = 40 km/hour

Thus, the average speed in km per hour is 40 km/hour if a motorist travels 100km in 2 1/2 hours the answer is 40 km/hour.

Answer:

You can buy 32 pens for £8.

Step-by-step explanation:

12÷3 =  4  ---> which means you get 4 pens for £1.

since you get 4 pens for £1, you need to multiply 4x8 to find how many pens you can buy for £8.

4x8 = 32.

You can buy 32 pens for £8.

hope this helps !

Answer:

Slope: [tex]-\frac{1}{2}[/tex]

Y-intercept: 3

Equation:  [tex]y =-\frac{1}{2} x + 3[/tex]

Step-by-step explanation:

The line intercepts the y-axis at the point (0, 3).

The line appears to be rising by -1 and running by 2. This gives us the slope, [tex]-\frac{1}{2}[/tex].

We can use these two parts to put together the equation: [tex]y =-\frac{1}{2} x + 3[/tex]

Hope this helps! Let me know.

Answer:

-1.555 and 1.555

Step-by-step explanation:

For a standard normal distribution:

P(- Ƶ ≤ Z ≤ Ƶ) = 0.88

The normal distribution on the curve is symmetrical about Z = 0

Thus

P( -Ƶ ≤ Z ≤ 0) = P( 0 ≤ Z ≤ Ƶ)

However;

This implies that:

P( -Ƶ ≤ Z ≤ 0)  +  P( 0 ≤ Z ≤ Ƶ) = 0.88

2P ( 0 ≤ Z ≤ Ƶ)  = 0.88

P( 0 ≤ Z ≤ Ƶ) = 0.44

P(Z ≤ Ƶ) - P( Z ≤ 0) = 0.44

Since P(Z ≤ 0) = 0.50

P(Z ≤ Ƶ) = 0.44 + 0.50

P(Z ≤ Ƶ) =  0.94

From the probability value table

z = 1.555

Thus the endpoints are:

-1.555 and 1.555

Answer:

stacy's response is correct.

Step-by-step explanation:

in geometry class, they are asked to describe the dimensions of a plane based on the components that create a plane. stacy states that a plane has two dimensions because it is made up of an infinite number of lines.

Answer:

Stacy

Step-by-step explanation:

the definition of a plane is "a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point, a line and three-dimensional space" so stacy has to be right

Answer:

196

Step-by-step explanation:

70/252= 3.5

56x3.5=196

The length of the smallest side of Δ DEF is 196 units.

Similar triangles have the same corresponding angle measures and proportional side lengths.

Given that, triangles ABC and DEF are similar. the lengths of the sides of ABC are 56, 64, and 72. the length of the largest side of DEF is 252.

Largest side of Δ ABC = 72 and that of Δ DEF = 252

We know that, corresponding sides of similar triangles are in equal proportion,

Therefore, the scale factor = 252 / 72 = 3.5

The smallest side of Δ ABC = 56

Therefore, the smallest side of Δ DEF = 56 x 3.5 = 196

Hence, the length of the smallest side of Δ DEF is 196 units.

Answer:

Which function please explain

Answer:

Value of slope is -2 and y-intercept is 1

Step-by-step explanation:

We can see that the values in the table have a linear relationship.

A linear function is a straight line written as:

y = mx+b

Here,

m is the slope and b is the y-intercept

The slope is calculated by:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

We can take any two consecutive pairs in the table to calculate the slope.

Taking first two input-output pairs.

(x1,y1) = (-3, 7)

(x2,y2) = (-2, 5)

Putting the values

[tex]m = \frac{5-7}{-2+3}\\m= -2[/tex]

Putting the value of m in the general form

[tex]y = -2x+b[/tex]

To find the value of b, we will put any pair of input-output (x,y) in the equation

Putting the first pair

[tex]7 = -2(-3) +b\\7 = 6 + b\\b = 7-6\\b = 1[/tex]

Hence,

Value of slope is -2 and y-intercept is 1
