Leah is measuring the weight of adult rhinos at the zoo. which unit of measurement should she use to eliminate the need to write the values in scientific notation? grams? feet? gallons? tons?

Leah should use tons to write the values in scientific notion.

Step-by-step explanation:

Leah is measuring the weight of adult rhinos at the zoo. She need to write the values in scientific notation, so here is the details of which unit of measurement should she use

Grams : A metric unit of mass equal to one thousandth of Kilogram, used for light weights which can easily lift it up by one hand.

Feet : This is used to measure Length.

Gallons : This is used to measure a large volume of liquid.

Tons : This unit is used for heavy weights 1 Ton is almost equal to 2000 pounds or 1000 kg.

As adult Rhino is heavy in weight, so Leah should use tons to write the values in scientific notion.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
