$Simplify 8 -2/3 please (leave as fraction) - 1$

Answers

Answer 1

Answer: $8^{-(2)/(3)}=\left(2^3\right)^{-(2)/(3)}=2^{3\cdot(-(2)/(3))}=2^(-2)=\left((1)/(2)\right)^2=(1)/(4)$

Answer 2

Answer: $8^{-(2)/(3)}=\n \left((1)/(8)\right)^{(2)/(3)}=\n \sqrt[3]{\left((1)/(8)\right)^2}=\n \sqrt[3]{(1)/(64)}=\n (1)/(4)$

Answers

Answer:

r=2

Step-by-step explanation:

r + 8 r + 11 = 29

( 1 + 8 ) r + 11 = 29 9 r + 11 = 29

Now we can isolate and solve for r while always keeping the equation balanced: First, subtract 11 from each side of the equation:

9 r + 11 − 11 = 29 − 11

9 r + 0 = 18

9 r = 18

Now we can divide each side of the equation by 9 to get

r : 9 over 9 = 18 under 9

1 r = 2

r = 2

Answer: r = 2

Steps:

r + 8r + 11 = 29

9r + 11 = 29

9r + 11 - 11 = 29 - 11

9r = 18

r = 2

Step-by-step explanation:

Leo is purchasing a bike that is on sale for 30% off. He knows the function that represents the sale price of his bike is c(p) = 0.7p, where p is the original price of the bike. He also knows he has to pay 12% sale's tax on the bike. The price of the bike with tax is f(c) = 1.12c, where c is the sale price of the bike.Determine the function that can be used to calculate the final price of Leo's bike by solving for f[c(p)].

f[c(p)] = 1.82cp

f[c(p)] = 1.82p
f[c(p)] = 0.784cp
f[c(p)] = 0.784p

Answers

Given:
sales discount = 30%
sales tax = 12%

c(p) = 0.7p where p is the original price
f(c) = 1.12c where c is the sales price of the bike.

f[c(p)] = 1.12(0.7p)

f[c(p)] = 0.784p Last option.

Assume: p = 100
c(100) = 0.7(100) = 70
f(70) = 1.12(70) = 78.4

f[70(100)] = 0.784(100) = 78.4

Step-by-step explanation:

What is the slope of a line that is perpendicular to the line y=1/6x+4?

Answers

The slope would be -6 because it is the opposite reciprocal. Not just the reciprocal.

Slope of a line that is perpendicular to the given line is -6.

What is slope?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Given equation

$y=(1)/(6)x+4$

It is in the form of $y=mx+b$

Comparing two equations

Slope :

$m =(1)/(6)$

Slope of a line that is perpendicular to the line:

= $-(1)/(m)$

= $-(1)/((1)/(6) )$

= -6

Slope of a line that is perpendicular to the given line is -6.

A recent survey by the American Cancer Society shows that the probability that someone is a smoker is P(S) = 0.19. It has also determined that the probability that someone has lung cancer, given that he or she is a smoker, is P(LC|S) = 0.158. What is the probability (rounded to the nearest hundredth) that a random person is a smoker and has lung cancer P(S ∩ LC)?0.03
0.83

Answers

P(LC / S) = P(S intersect LC) / P(S)
P(S intersect LC) = P(S)*P(LC / S) = 0.19 * 0.158 = 0.03
