Each Americana chicken lays 2 eggs per day and each Delaware chicken lays 1 egg per day.
marissa [1.9K]

Answer:

$30

Step-by-step explanation:

-One week has 7 days, so the total number of eggs laid by both chickens:

Americana=2\times 7=14\\\\Delaware=1\times 7=7\\\\t=21\ eggs

-One doze is equivalent to  12 items. There's only one full dozen unit in 21 pieces.

Amount =12\times 2.5\\\\=30

Hence, she makes $30 in week one.

The values of a,b, and c in scientific notation are 3.47 x 10^-6, 4.61 x 10^-7, and 5.52 x 10^-7, respectively. Complete the fol
Mars2501 [29]

Answer:

a)  1.59967 * 10 ^-12

b)    7.52711497

c)  1.590778098 * 10^-1

Step-by-step explanation:

a= 3.47 x 10^-6,

b=4.61 x 10^-7,

c=5.52 x 10^-7

a)  a*b =  3.47 x 10^-6* 4.61 x 10^-7

We multiply the numbers out front and add the exponents

        (3.47*4.61) * 10^(-6+-7)

        15.9967 * 10^-13

But this is not correct scientific notation, we need 1 number in front of the decimal.  Move the decimal 1 place to the left and add 1 to the exponent

1.59967 * 10^(-13+1)

1.59967 * 10 ^-12

b)   a/b = 3.47 x 10^-6/ 4.61 x 10^-7

We divide the numbers out front and subtract the exponents

        (3.47/4.61) * 10^(-6- -7)

         (3.47/4.61) * 10^(-6+7)

         .752711497* 10^1

But this is not correct scientific notation, we need 1 number in front of the decimal.  Move the decimal 1 place to the right and subtract 1 from the exponent

7.52711497* 10^1-1

7.52711497

c)  c/a = 5.52 x 10^-7/3.47 x 10^-6

We divide the numbers out front and subtract the exponents

        (5.52/3.47) * 10^(-7- -6)

        (5.52/3.47) * 10^(-7+6)

          1.590778098 * 10^-1

Calculate the slope of the line between the point (-3,2) and (5,0)
Finger [1]

Answer:

The slope of the line is -1/4

Step-by-step explanation:

To find the slope, we use the formula

m = (y2-y1)/(x2-x1)


We have the points  (-3,2) and (5,0)

  = (0-2)/(5--3)

  = (-2)/(5+3)

  =-2/8

 = -1/4

The slope of the line is -1/4
