Answer:

5 3/7 hours

Step-by-step explanation:

\frac{7}{8}h + 1\frac{1}{4}=6\\\\\frac{7}{8}h+\frac{5}{4}=6\\\\\frac{7}{8}h=6-\frac{5}{4}\\\\\frac{7}{8}h=\frac{6*4}{1*4}-\frac{5}{4}\\\\\frac{7}{8}h=\frac{24}{4}-\frac{5}{4}\\\\\frac{7}{8}h=\frac{19}{4}\\\\h=\frac{19}{4}*\frac{8}{7}\\\\h=\frac{19*2}{7}\\\\h=\frac{38}{7}\\\\h=5\frac{3}{7}

zalisa [80]

Answer:

s = 2t

Step-by-step explanation:

At the end of a snow storm, Audrey saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 2 inches per hour. Write an equation for S, in terms of t, representing the depth of snow on Audreys lawn, in inches, t hours after the snow stopped falling.

2 inches = 1 hour

10 inches = x hour

2x = 10

x = 10/2

x = 5

Creating an equation

S ∝ t

S = kt

k = s/t

k = 2/1

k = 2

The equation for S, in terms of t, representing the depth of snow on Audreys lawn, in inches, t hours after the snow stopped falling is

S = 2t

FROM A SQUARE SHEET OF CARDBOARD OF SIDE 20cm ,SECTORS OF ECAH RADIUS 7cm IS CUT OFF FROM EACH CORNER.THEN AREA OF REST OF THE C
VikaD [51]

Answer:

246 cm^2

Step-by-step explanation:

Area of the rest of cardboard = Area of square - Area of the 4 sectors

Kindly note that at each corner of the cardboard, the angle is 90 degrees

Area of square = L^2 = 20^2 = 400 cm^2

Area of a sector = theta/360 * pi * r^2

Since we have 4 sectors;

Area of sectors =4 * 90/360 * 22/7 * 7 * 7

= 22/7 * 49 = 22 * 7 = 154 cm^2

Area of the remaining part of cardboard = 400 cm^2 - 154 cm^2 = 246 cm^2
