Answer:

Kerri's speed = 50 mile per hour. Therefore option (D) is true.

Step-by-step explanation:

Given the distance-time graph

It is clear from the distance-time graph that:

  • at Time = 1 hour, Distance = 50 miles
  • at Time = 2 hours, Distance = 100 miles

so the two points on the distance-time graph is:

  • (1, 50)
  • (2, 100)

Finding the slope between the points to determine the speed.

Please note that the slope between the points represents the speed or rate of change.

Speed = Rate of change = y₂-y₁ / x₂-x₁

                                         = 100 - 50 / 2-1

                                          = 50 / 1

                                           = 50 miles per hour

Thus, Kerri's speed = 50 mile per hour. Therefore option (D) is true.

You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00. How much
Veseljchak [2.6K]

Answer:

$2.69

Step-by-step explanation:

The original prices of the books are $2.50, $4.95, and $6.00.

You want to buy three books that are on sale at 20% off (or 0.2 as decimal).

In total, you'll save:

0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6

Uce distributive property:

0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6\\ \\=0.2\cdot (\$2.50+\$4.95+\$6.00)\\ \\=0.2\cdot \$13.45\\ \\=\$2.69
