Write an equation perpendicular to y = 3/4x that passes through the point(3,-3)

ryzh [129]

Step-by-step explanation:

the slope perpendicular to y= ¾x is

-1 ÷ ¾ = -4/3

so the equation :

y-(-3)= -4/3(x-3)

y+3= -4/3x +4

y = -4/3x +4-3

y = -4/3x + 1

100,000^1/5 x a + 1,000,000^1/2 x a

frez [133]

Answer:

1010a

Step-by-step explanation:

Mathematically, when a number is raised to a fraction, it simply means we are to find the root of that number to the denominator of the given fraction

For example;

100,000^1/5

= 5 x√((100,000) = 10

Likewise;

1,000,000^1/2 = √(1,000,000) = 1000

Thus, we have it that;

10 * a + 1000 * a

= 10a + 1000a = a(1000 + 10) = 1010a

Sally can paint the wall in 54 minutes. If Sally and Ethan work together, they can paint the wall in 36 minutes. How much time d

MAXImum [283]

Answer:

$108\ minutes$

Step-by-step explanation:

1) we know that

Sally can paint the wall in 54 minutes

The 100% of the wall ------> she can paint in 54 minutes

by proportion

calculate how much is the percent of the work in 36 minutes

$\frac{100\%}{54} =\frac{x\%}{36}\\ \\x=36*100/54\\ \\x=66.67\%$

That means

Sally in 36 minutes can paint the 66.67% of the wall

2) Sally and Ethan work together, they can paint the wall in 36 minutes

Ethan in 36 minutes can paint (100%-66.67%)=33.33%

by proportion

Calculate how much time does it take for Ethan to paint the wall by herself

$\frac{33.33\%}{36} =\frac{100\%}{x}\\ \\x=36*100/33.33\\ \\x=108\ minutes$
