Line segment AB measures 18 units. A number line with no numbers. A closed circle above the line is labeled A. A closed circle nine notches down the line is labeled B. The space between point A and the next notch is labeled d. What is d, the distance between tick marks on the number line? 1 unit 2 units 3 units 9 units

Answers

Answer 1

Answer:

Answer: 2 units

Step-by-step explanation:

Given that :

Length of of line segment (AB) = 18 Units

d = distance between point A and successive notch

Number of notches between point A and B = 9

If the length of line AB = 18 units and the number of notches between point A and B = 9

Then distance d, between successive tick marks :

Length of Line segment / number of notches or tick marks between A and B

= 18 units / 9

= 2 units.

Hence distance between tick marks on the number line is 2 units.

Newton and his friends were watching a movie. They watch 50% of the movie and then take a break. Then they watch the remaining 65 minutes of the movie. How long was the whole movie

Answers

The length of the whole movie was 130 minutes.

Let's call the length of the whole movie "x". According to the problem, Newton and his friends watch 50% of the movie before taking a break. This means they watched 0.5x minutes of the movie.

After the break, they watch the remaining 65 minutes of the movie. So the total time they watched the movie is:

0.5x + 65

But we know that the total time they watched the movie is the same as the length of the whole movie "x". So we can set these two expressions equal to each other and solve for "x":

0.5x + 65 = x

Subtracting 0.5x from both sides, we get:

65 = 0.5x

Dividing both sides by 0.5, we get:

x = 130

Therefore, the length of the whole movie was 130 minutes.

Which choice is equivalent to the quotient shown here when x > 0?√72x^3 divide by square root of 50x^2

Answers

Answer:

$(3√(2x))/(5)$

Step-by-step explanation:

Starting point:

$(√(72x^3))/(50x^2)\n$

1) Factor it by Prime Factor Method 72 and 50

$72|2\n 36|2\n 18|2\n 9|3\n3|3\n 1\n 72=2^2*3^2*2$

$50|2\n 25|5\n 5|5\n 1\n 50=2*5^2$

2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.

$(√(72x^2*x))/(50x^2)=(6x√(2x))/(5x√(2))=(6√(x))/(5√(2))$

3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.

$(6√(x))/(5√(2))*(√(2))/(√(2))=(6√(2x))/(10)=(3√(2x))/(5)$

N+5/16=-1 what is the answer?

Answers

$(n+5)/(16)=-1$

$n+5=-16$

$n=-21$

if this is (n+5)/16 = -1, then the answer is -21. if this is n + (5/16) = -1, then the answer is -(21/16)

I followed the numbers across, thinking to myself "this won't be
too hard to multiply, because they're all small numbers". And then
when I got to the zero, I burst out laughing ! It doesn't matter at all
what all the other numbers are. Once there's a zero in there, the whole
product will be zero, no matter what else gets multiplied along the way.
There could be millions and billions in there. You wouldn't need to do
any calculating at all. With zero as a factor, you know right away that
the product is zero.

So your question is
$\sf{2*3*6*4*7*5*}$ $\bf{0}$ $\sf{*4*5=}$

We need to use this property:
$\sf{a * 0=0}$

So then your problem has one number that is a 0. And all these numbers are getting multiplied. That means you could have like a million numbers, but if you multiply it by 0 even once, your final answer will be 0.

So your final answer is

$\boxed{\bf{0}}$
