Answer
Find out the how many shorter pieces can a seamstress cut.
To prove
Let us assume that the number of shorter pieces cut be x.
As given
A seamstress has a piece of cloth that is 3 yards long.
she cuts it into shorter lengths of 16 inches each.
As
1 yards = 36 inches
Now convert 3 yards into inches.
= 3 × 36
= 108 yards
Than the equation becomes
16x = 108
x = 6.75
Therefore the number of shorter pieces be 6 .
Part A The equation to model this would be
240-( 240- 6.5x + 9) = y
x is the minutes the balloon decreases in altitude
Part B plug in x
240- (240 - 6.5(15) + 9) = y
y = 106.5
expression answer: 106.5
Part C altitude is 133.5 (240 - 106.5)
<span> lets say integrand is e^(y/x):
∫(x = 0 to 1) ∫(y
= 0 to x^2) e^(y/x) dy dx
= ∫(x = 0 to 1) xe^(y/x)
= ∫(x = 0 to 1) x(e^x - 1) dx
= ∫(x = 0 to 1) (xe^x - x) dx
= (xe^x - e^x) - (1/2)x^2
= 1/2. </span>
100/200 that is the question
If you divide 5 over 3 you get the decimal 1.6, not 15.
the
correct answer would be 45. how do i get that? read below.
________________________________
to solve:
1.multiply each side by 3, to get the 3 on the left side to cancel out. so you get x = 15 times 3.
2. 15 * 3 =
45
