Anna71 [15]

Answer:

19.17 foot

19 foot( to the nearest whole number)

Step-by-step explanation:

Kaithlyn has purchased 46 foot long piece of lace.

She needs 322 inches of lace for the quilt.

Since we are required to find the length of lace remaining in foot, we simple convert all units to foot before carrying out our calculations.

12 inches = 1 foot

322 Inches = 322÷ 12= 26.83 foot

Her remaining length of lace

=Total Length - Length Used

=46-26.83

=19.17 foot

=19 foot( to the nearest whole number)

Answer:

$109.45

Step-by-step explanation:

On Monday in the morning you worked 4 hours, so plug in the equation.

12.50(4)= $50

On Monday in the afternoon you worked 4 hours and 45 min

12.50(4) = $50

Then do 12.50/60 to get .208 ≈ .21

So 45(.21) = $9.45

50 +50 + 9.45= 109.45

Serjik [45]
A= (-4,2)

The x value (-4) stays the same when reflected over the x-axis, so only the y-value gets reflected and therefore changed.
The resultant coordinate is (-4,2)
