Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per

horrorfan [7]

The speed of slower car is 45 mph and faster car is 50 mph.

Step-by-step explanation:

Given,

Distance covered by both cars = 190 miles

Time taken by both of them = 2 hours

Let,

x be the speed of slower car.

Speed of faster car = x+5

Combined speed = x+x+5 = 2x+5

We know that;

Distance = Speed * Time

$190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\$

Dividing both sides by 4

$\frac{4x}{4}=\frac{180}{4}\\x=45$

Speed of slower car = 45 miles per hour

Speed of faster car = 45+5 = 50 miles per hour

The speed of slower car is 45 mph and faster car is 50 mph.

The points at the corners of the given figure are ...

(0, 0), (0, 4), (3, 4), (3, 0)

When the figure is scaled by a factor of 1/3, each of the coordinates is multiplied by 1/3:

(0, 0), (0, 4/3), (1, 4/3), (1, 0) . . . . . points scaled by 1/3

When the figure is scaled by a factor of 3/2, each of the coordinates is multiplied by 3/2:

(0, 0), (0, 6), (9/2, 6), (9/2, 0) . . . . . . points scaled by 3/2

The answer is B, because A and C are automatically eliminated because they are subtracting, and the equation that represents the situation is an addition inequality. B is correct because the two parenthesis numbers represents the students attending the fair paying $0.50, and there are 200 students. The 2.25a represents an amount of adults, each paying $2.25.

Decrease 1.25 km by 0.6%

Anna35 [415]

Answer:

124250cm, 1242.5m or 1.2425km

Step-by-step explanation:

0.6% = 6/100

6/100 = 0.006

0.006*1.25 = 0.0075

1.25km = 1250m = 125000cm

0.0075km = 7.5m = 750cm

125000 - 750 = 124250

Therefore:

The answer is 124250cm, 1242.5m or 1.2425km
