To solve this equation with algebra
4/7 = 1/x
(4/7)x = (1/x)x
4x/7 = 1
(4x/7)7 = 1(7)
4x = 7
4x/4 = 7/4
x = 1.75
1.75 yards of fabric are needed to make 1 dress.
Hope this helps! <3
Answer:
412in
Step-by-step explanation:
Answer:
The answer in the simplest form would be 28/9 or 3 1/9
Step-by-step explanation:
Very simple you would divide the 56 and the 18 by 2 and you get 28/9.
or you could change it to a improper fraction in that case it would be 3 1/9
Answer:
quadrilateral, trapezoid
Step-by-step explanation:
ummmmmmm knowledge is my explanation :)
(d) The particle moves in the positive direction when its velocity has a positive sign. You know the particle is at rest when
and
, and because the velocity function is continuous, you need only check the sign of
for values on the intervals (0, 3) and (3, 6).
We have, for instance
and
, which means the particle is moving the positive direction for
, or the interval (3, 6).
(e) The total distance traveled is obtained by integrating the absolute value of the velocity function over the given interval:

which follows from the definition of absolute value. In particular, if
is negative, then
.
The total distance traveled is then 4 ft.
(g) Acceleration is the rate of change of velocity, so
is the derivative of
:

Compute the acceleration at
seconds:

(In case you need to know, for part (i), the particle is speeding up when the acceleration is positive. So this is done the same way as part (d).)
