Your answer is 1:-4. This is because when you divide each term by -4, that is the number in the next term.

pochemuha

Answer: a) 1977060966, b) 146581344.

Step-by-step explanation:

Since we have given that

There are 10 numbers,

There are 26 lower case letters,

There are 26 upper case letters,

Since the first 3 characters have to be digits and next 6 can be upper or lower.

So, a) repetitions are allowed:

$10^3\times (26+26)^6\\\\=10^3\times 52^6\\\\=1977060966$

b) repetitions are not allowed:

$^{10}P_3\times ^{52}C_6\\\\=720\times 20358520\\\\=146581344$

Hence, a) 1977060966, b) 146581344.

The figure represents the shape of a kitchen floor. What is the area? (round to the nearest hundredth)

Murljashka [212]

We would divide the shape into a rectangle and a trapezium

The rectangle is of length, 24.5 ft and width 10.75 ft

Area = 24.5 * 10.75 = 263.375 square feet.

Trapezium : Parallel sides are 18.5 ft and 24.5 ft
Height: 12 - 10.75 = 1.25ft

Area of Trapezium = (1/2)*(Sum of Parallel sides)*height

= 1/2 * (18.5+24.5)* 1.25
= 1/2 * 43* 1.25 = 26.875

Total Area = Area of Rectangle + Area of Trapezium

= 263.375 + 26.875 = 290.25

Area = 290.25 ft² (D)
