An average African elephant weighs about 9,072 pounds. How is this number written in scientific notation?
qwelly [4]

Answer:9.072×10³

Step-by-step explanation:

A number is said to be written in a scientific notation or standard form if it is expressed in the form a×10n where 1 is less than or equal to a and a is less than 10 and n is an integer

9072 is more than 10

So 9072÷10=907.2

Still 907.2 is more than 10

So 907.2÷10=90.72

Still 90.72 is more than 10

So 90.72÷10=9.072

9.072 is less than 10

We divided 9072 by 1000 and 1000 as a power of ten is 10³

So the answer is 9.072×10³

Marco has ( d + 14.55 ) $

Step-by-step explanation:

Marco's mom gave him d dollars for his allowance one week.

Allowance of one week = d $

He also earned $ 1 4 . 5 5 for his newspaper route that week.

Earning of Marco by selling newspaper route that week = 14.55 $

Total earning = Allowance of one week + Earning of Marco by selling newspaper route that week

Total earning = ( d + 14.55 ) $

So Marco has ( d + 14.55 ) $

Does anyone know to do this!
Rina8888 [55]
Answer: (r + 4)(r + 8)
Alright, I would first rearrange the equation by bringing all your terms to one side by adding 12r and 32 to both sides. This will result in the rearranged equation: r^2+12r+32=0
You can then factor the equation into the two binomials: (r + 4)(r + 8).
4 + 8 equals the b term, 12, and 4 x 8 equals the c term, 32.

The length of each side of a square is 3 in. more than the length of each side of a smaller square. The sum of the areas of the
dolphi86 [110]

Answer:

Step-by-step explanation:

let the smaller square be A, and the side is a

larger square is B, the side is a+3

Area(A)=a^2

Area(B)=(a+3)^2

a^2+(a+3)^2=425 in^2

a^2+a^2+6a+9=425

2a^2+6a=425-9

2(a^2+3a)=416 we divide by 2

a^2+3a=208

we solve the quadratic function

we will get two roots, a(1)=13, and the negative answer we will ignore

a=13 and the side of the larger square is 13+3=16
