andriy [413]

Answer:

78,624,000 license plates

Step-by-step explanation:

For each of the 4 numbers, we have the following possibilities:

First number: 10 digits possible

Second number: 9 digits possible (one used)

Third number: 8 digits possible (two used)

Fourth number: 7 digits possible (three used)

For each of the 3 letters, we have the following possibilities:

First letter: 26 digits possible

Second letter: 25 digits possible (one used)

Third letter: 24 digits possible (two used)

The total number of license plates is the product of all these possibilities:

Number of plates = 10 * 9 * 8 * 7 * 26 * 25 * 24 = 78,624,000 license plates

The number of kids in a robotics club grew from 23 to 31. What was the percent increase in the number of kids in the club? Round

konstantin123 [22]

Answer: $35\%$

Step-by-step explanation:

For this exercise you need to use the following formula:

$\%increase=\frac{New\ value-Old\ value}{Old\ value}*100$

According to the exercise, the number of kids in a robotics club grew from 23 to 31; then you can identify that:

$New\ value=31\\\\Old\ value=23$

Knowing these values, you can substitute them into the equation and then evaluate, in order to find the percent increase in the number of kids in the club. Then:

$\%increase=\frac{31-23}{23}*100\\\\\%increase=34.78\%$

Rounding it to the nearest whole percent:

$\%increase=35\%$
