Nathan work on the puzzle for 1 1/2 hours chloe spent four times as much working on her puzzle. how many hours did it chloe spend on her puzzle?
answer: option d is correct .
in order to find the same attendance we set both equation equal
8x+191 = -x^2+26x+126
simplifying equation ,we get
(x-5) (x-13) = 0
x =5 or x =13
therefore on 5th day and 13th day both plays attendance is same
and it is obtained by plugging x = 5 in and x =13 in either of the equation.
for x = 5 ,
y = 8(5) +191 = 40+191 = 231
for x = 13
y = 8(13)+191
therefore option d is correct
the diagonal of a rectangle splits the rectangle into two equal right triangles. the legs of the triangle are 6cm and 8cm. this means the pythagorean theorem can be applied to find the third side of the triangle.
the pythagorean theorem is .
here a= 6 and b=8.
hello from mrbilldoesmath!
didn't get an answer from you so i'll assume the cheetah runs at 70 miles/hour. since 1 mile = 5280 feet,
70 miles/hour * 5280 feet/mile = (note how the "mile" units cancel)
70 * 5280 feet/hour =
