8,500,00 is the answer to the nearest 100,000 because 473 is the hundreds place and since 7 is above 5 you round up

Remember this: 4 or below let it go (round down) 5 or above give it a shove (round up)

remember your only rounding 100,000 place so leave the digit behind that

answer: 8,000,000 since it is 4 or below.

Sanjay and Felipe are putting together a 500-piece puzzle. Sanjay could do the entire puzzle by himself in 6 hours, while it wou

Nata [24]

What is the time it takes Sanjay to complete the puzzle? 6 hours

What is the time it takes Felipe to complete the puzzle? 8 hours

We can use the general formula of rate and time to solve this problem. Generally we have,

Rate * Time = Work/Job

** where Work/Job for this problem is 1 since they are doing 1 work, which is solving a puzzle

Finding rate of Sanjay:

$R(6)=1\\R=\frac{1}{6}$

Finding rate of Felipe:

$R(8)=1\\R=\frac{1}{8}$

Working together, their rate is the sum,

Total Rate = $\frac{1}{6} + \frac{1}{8} = \frac{7}{24}$ .

Using the general formula again, we can find the time it will take to solve the puzzle when both works together.

$(\frac{7}{24})T=1\\ T=\frac{1}{\frac{7}{24}}= \frac{24}{7} = 3.43$ hours

Rounding the answer, we have 3.4 hours.

ANSWER: 3.4 hours

Show all work to identify the asymptotes and zero of the faction f(x) = 4x/x^2 - 16.

Reptile [31]

Answer:

asymptotes: x = -4, x = 4
zeros: x = 0

Step-by-step explanation:

The vertical asymptotes of the rational expression are the places where the denominator is zero:

x^2 -16 = 0

(x -4)(x +4) = 0 . . . . . true for x=4, x=-4

x = 4, x = -4 are the equations of the vertical asymptotes

The zeros of a rational expression are the places where the numerator is zero:

4x = 0

x = 0 . . . . . . divide by 4

ANSWER B

Step-by-step explanation:

d=(120-4t)

30=120-4t

4t=120-30=90

t=90/4=22.5 s

-30==120-4t

4t=120+30=150

t=150/4=37.5 s
