Answer:

n = -3/10

Step-by-step explanation:

Given the expression \frac{\sqrt[5]{b} }{\sqrt[]{b} }

\frac{\sqrt[5]{b} }{\sqrt[]{b} } \\= \frac{b^{1/5}}{b^{1/2}} \\= b^{1/5-1/2}\\= b ^{2-5/10}\\= b^{-3/10}\\Compare \ b^n \ with \  b^{-3/10}\\\\n = -3/10

Find the area of the figure shown.
astraxan [27]

Answer:220

Step-by-step explanation:

LET X BE THE LENGTH OF RECTANGLE AND FOR UPPER PORTION OF DIA GRAM BASE OF RIGHT ANGLE TRIANGLE SO X=20

LET Y BE WIDTH OF RECTANGLE SO Y=8

LET P BE THE PERPENDICULAR OF THE RIGHT TRIANGLE SO P=6

THEN

AREA OF RECTANGLE=LENGTH*WIDTH

SO AREA OF RECTANGLE BECOMES=(20)(8)=160

AND AREA OF RIGHT ANGLE TRIANGLE BECOMES=1/2(BASE*(PERPENDICULAR)

SO =1/2(20)(6)=60

SO THE TOTAL AREA OF THE DIAGRAM=AREA OF RIGHT ANGLE TRIANGLE+AREA OF RECTANGLE=160+60=220

0.5(x+0.1)-0.1(x-0.5)
Rom4ik [11]

Answer: 0.4x + 0.1

Step-by-step explanation: Distribution.

0.5(x+0.1)-0.1(x-0.5)

0.5 times x = 0.5x

0.5 times 0.1 = 0.05

First step: 0.5x + 0.05

Distribute next part

-0.1 times x= -0.1x

-0.1 times -0.5 = 0.05

-0.1x + 0.05

Put together: 0.5x + 0.05 -0.1x + 0.05

Combine like terms:

0.5x -0.1x = 0.4x

0.05 + 0.05 = .1

Answer: 0.4x + 0.1
