Answer:

Carl traveled 281.25 km by bus and 1,618.75 km by plane.

Step-by-step explanation: v1 = 60 km/h average speed by bus to Toronto

v2 = 700 km/h average speed by plane to Winnipeg

d = 1,900 km the total distance traveled

t = 7 h total traveling time

t1 = the time of the travel by bug

t2 = the time of the travel by plane

t = t1 + t2 the total time

d1 = the distance traveled by bus

d2 = the distance traveled by plane

d = d1 + d2 the total distance

Since average speed = distance/time we have time = distance/avg.speed

t1 = d1/v1 that is t1 = d1/60

t2 = d2/v2 that is t2 = d2/700

Plug the above values into t1 + t2 = t.

We have the following system of equations:

d1/60 + d2/700 = 7

d1 + d2 = 1900

d1 = 281.25 km

d2 = 1,618.75 km

Carl traveled 281.25 km by bus and 1,618.75 km by plane.

Malik is standing outside in the sun. Malik is 72 inches tall, and his shadow is 60
anastassius [24]

Jeremy's height is 67.2 inches

The diagram below represents situation

<h3>Proportion</h3>

Proportion says that two ratios (or fractions) are equal. This a mathematical comparison between numbers.

Therefore, let's establish the proportion in this situation

  • Malik height / Malik shadow = Jeremy height / Jeremy shadow

Therefore,

  • 72 / 60 = x / 56

cross multiply

72 × 56 = 60x

60x = 4032

divide both sides by 60

x = 4032 / 60

x = 67.2

Therefore, Jeremy's height is 67.2 inches

In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon​
pochemuha

Answer:

18 sides.

Step-by-step explanation:

The interior and exterior angles sum to 180 so:

       I + E = 180

also  I - E = 140       (given)

So, adding to eliminate E:

      2I = 320

I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.

Since the sum of all exterior angles in a polygon = 360 degrees

- the number of sides = 360 / 20 = 18.

Which region represents the solution to the given system of inequalities? y&lt;-1/2x and y&gt;_2x+3
Tresset [83]

The region is C is the correct option because intersection region is on the region C after drawing on the coordinate plane.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The question is incomplete:

The complete question is:

Which region represents the solution to the given system of inequalities?

  • A
  • B
  • C
  • D

y < -1/2x and y ≥ 2x+3 and the missing figure is shown in the picture please refer to the picture.

We have two inequalities:

y < -1/2x

y ≥ 2x+3

After drawing the inequalities on the coordinate plane we see that the intersection region is on the region C.

Thus, the region is C is the correct option because intersection region is on the region C after drawing on the coordinate plane.
