In a certain state, license plates each consist of 2 letters followed by either 3 or 4 digits. How many differen license plates

coldgirl [10]

Answer:

26 × 26 × 10 × 10 × 10 = 676 , 000 possibilities

Step-by-step explanation:

There is nothing stating that the letters and numbers can't be repeated, so all 26 letters of the alphabet and all 10

digits can be used again.

If the first is A, we have 26 possibilities:

AA, AB, AC,AD,AE ...................................... AW, AX, AY, AZ.

If the first is B, we have 26 possibilities:

BA, BB, BC, BD, BE .........................................BW, BX,BY,BZ

And so on for every letter of the alphabet. There are 26 choices for the first letter and 26 choices for the second letter. The number of different combinations of 2 letters is: 26 × 26 = 676

The same applies for the three digits. There are 10 choices for the first, 10

for the second and 10 for the third:

10 × 10 × 10 = 1000

So for a license plate which has 2 letters and 3 digits, there are: 26 × 26 × 10 × 10 × 10 = 676 , 000 possibilities.

Hope this helps.

Write the decimal as a fraction or a mixed number in simplest form

natka813 [3]

-0.258 is a decimal number in which 2 is at the tenth place, 5 is at the hundredth place and 8 is at the thousandth place.

Therefore, the number in the fraction form is - $-\frac{258}{1000}$

The fraction in the simplest form is - $-\frac{129}{500}$

-0.312 is a decimal number and its fraction form is - $-\frac{312}{1000}$

The fraction in the simplest form is $-\frac{78}{250} =-\frac{39}{125}$

-2.32 is a decimal number and its fraction in the simplest form is

$-2\frac{32}{100} =-2\frac{8}{25}$

-1.64 is a decimal number and its mixed number in the simplest form is $-1\frac{64}{100} =-1\frac{16}{25}$

6.012 is a decimal number and the number in mixed number form is $6\frac{12}{1000}=6\frac{3}{250}$

-12.405 is a decimal number and the number in mixed number form is

$-12\frac{405}{1000}=-12\frac{81}{200}$

Answer:

(1)C- Trapezoid

(2)D-20 square feet

Step-by-step explanation:

<u>Question 1</u>

A cross-section of a rectangular pyramid cut perpendicular to the base but not passing through the top will have two parallel sides where one of the sides will be longer. Therefore, the shape which describes the cross-section will be a trapezoid.

<u>Question 2</u>

The base of the Triangle = 5 feet

Height of the Triangle = 8 feet

$\text{Area of a triangle}=\dfrac12 \times $Base \times Height\\=\dfrac12 \times 5 \times 8\\=20 ft^2$
