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

You start driving north for 7 miles, turn right, and drive east for another 24 miles. At the end of driving, what is your straig
horsena [70]

Answer:

AC = 25\ miles

Step-by-step explanation:

Given:

Distance for north side = 7 miles.

Distance for east side = 24 miles.

We need to find the displacement.

Solution:

Figure shows Point A is starting point and AB = 7 miles is North side distance and BC = 24 miles is east side distance and AC is shown as displacement.

Using Pythagoras theorem to find displacement (AC).

(AC)^{2}=(AB)^{2}+(BC)^{2}

Substitute AB = 7 and BC = 24 in above equation.

(AC)^{2}=(7)^{2}+(24)^{2}

(AC)^{2}=49+576

(AC)^{2}=625

AC = \sqrt{625}

AC = 25\ miles

Therefore, displacement of the car AC = 25\ miles
