Brianna made cookies. She used 5/8 of a cup of flour and 1/2 of a cup of sugar. How much more flour than sugar did Brianna use?
KiRa [710]

Answer:

She used 1/8 or 12.5% more flour than sugar

Step-by-step explanation:

flour: 5/8

sugar: 1/2 = 4/8

\frac{5}{8} - \frac{4}{8} = \frac{1} {8}  = 0.125

0.125 = 12.5%

How do you do this question?
valkas [14]

Answer:

V = 91π / 6

Step-by-step explanation:

When we revolve the region about y = 2, we get a cylindrical shape on its side.  If we slice the shape into concentric shells, then each shell will have a radius of 2 − y, a thickness of dy, and a length of 7 − x.  The volume of the shell is:

dV = 2π r h t

dV = 2π (2 − y) (7 − x) dy

x = 7y², so:

dV = 2π (2 − y) (7 − 7y²) dy

dV = 14π (2 − y) (1 − y²) dy

dV = 14π (2 − 2y² − y + y³) dy

The total volume is the sum of all the shells from y=0 to y=1.

V = ∫ dV

V = ∫₀¹ 14π (2 − 2y² − y + y³) dy

V = 14π (2y − ⅔ y³ − ½ y² + ¼ y⁴) |₀¹

V = 14π (2 − ⅔ − ½ + ¼)

V = 91π / 6

Which of the following are ordered pairs for the equation y = 1/8x + 11
Anna11 [10]

Answer:

(0, 11) is a solution.

(8, 12)  is a solution.

(16, 13) is a solution

(1, 89/8)  

(2,  45/4)

Step-by-step explanation:

y = 1/8x + 11

for this equation....

y = (1/8) x + 11

let x = 0  get

y = 0 + 11 = 11

(0, 11) is a solution.

(8, 12)  is a solution.

(16, 13) is a solution

(1, 89/8)   because    y = 1/8 + 11 = 1/8 + 88/8 = 89/8

(2,  45/4)
