dexar [7]

Answer:

The equation you are asking for is

40*(t+3) = 55*t,

where t is the time counted after the second car started.

The equation says that the distance covered by each car from the starting point to the catching point is the same for both cars.

What is −3/8÷7/12 ?
RSB [31]

Answer:

-9/14

Step-by-step explanation:

This is my simplest-

Do the keep-change-flip method for this problem (and also any problem involving this)

KEEP -3/8

CHANGE the division sign to multiplication

FLIP the last fraction. 7/12 to 12/7

Now solve the problem by multiplying the fractions

-3/8 × 12/7 =

-3 × 12 = -36

8 × 7 = 56

-36 / 56 =

Simplify it by dividing the numerator (up of the line) and denominator (below the line) to get -9/14

Select from the following choices those graphs that represent only a dilation applied to this polygon with a scale factor great
romanna [79]

Answer:

B and C

Step-by-step explanation:

Required

Select graphs that are dilated by a scale factor greater than 1

For graph A:

Graph A is smaller than the original graph. This indicates dilation with a scale factor less than 1

For graph B:

Graph B is bigger than the original graph and is dilated over (0,0). This indicates dilation with a scale factor greater than 1

For graph C:

Graph C is bigger than the original graph; however, it is not dilated over (0,0). This indicates dilation with a scale factor greater than 1

For graph D:

Graph D is bigger than the original graph; however, it is not only dilated but also flipped over (i.e. rotated).

<em>Hence, b and c is true</em>
