NEED HELP FOR REAL 69 points!!!!!!!!!!!!!! ASAP
The physicist from the last problem lets the particle fall another 100 times, and finds that the average travel time is now 16 sec. Remember that when running the simulation many times it took 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. What does she conclude and why?

Answer:

y = - 4.98

Step-by-step explanation: This statement means

y

∝

, which can also be written in the form

y

=

k

x

when it is directly proportionate and

y

=

k

x

when inversely proportionate, where

k

is a value we need to work out. Since the equation is in the form

y

=

k

x

we know that...

∴

Answer:

The rate of change is 1.

The equation of a line and y-intercept form is

y = mx + b, where m = the slope of the line.

and our given equation y = x - 2 the slope of the line is 1 in other words y = 1x - 2

Answer:

32°

Step-by-step explanation:

1) the sum of the angles is 180°. According to this rule the sum can be written:

t+(t+1)+[180-(t+33)]=180;

2) if to solve this equation, then

t=32°

Step-by-step explanation:

the fraction 49/7 is the same as the problem 49÷7

If you do the problem, you get 7, and if you want to check you could do the inverse- 7x7=49. Since that checks out, 7 is your answer.

Hope this helps :)

Answer:

4/5

Step-by-step explanation:

the slope is the number next to x

y=mx+b is a model we use in math to find the slope. each letter is a place marker for different numbers.

slope is where the m is in the problem

in your case 4/5 is found in the same spot as m.

Answer:

3/7 ÷ 2/7 = 3/2

3/4÷5/6 = 9/10

Step-by-step explanation:

The key rule to understanding how to divide fractions is...

KEEP SWITCH FLIP!!!

Basically, you keep the first fraction, switch the sign from division to multiplication, and flip the other fraction...

Here's how you would go about this:

3/7÷2/7

Keep 3/7 and switch ÷ to multiplication

3/7 · 2/7

Now flip 2/7 so it becomes 7/2

3/7 · 7/2

Now multiply across!

3 · 7 = 21

7 · 2 = 14

You get 21/14...but don't forget to simplify!! Divide 21 and 14 by 7 to get 3/2!

And now...for 3/4 ÷ 5/6, you do the exact same thing!

Keep...3/4

Switch...  ÷

Flip...5/6

And you should get:

3/4 · 6/5

Multiply across...

= 18/20

Simplify!

= 9/10

I hope this helps clarify any confusion you may have had!

Answer:

1 1/2 and 5/8

Step-by-step explanation:

problem 1

3/7 divided by 2/7

flip 2nd fraction then multiply is formula

so 3/7 times 7/2 which is 21/14 which is 1 7/14 simplify to 1 1/2

2

so 3/4 times 5/6 remeber formula  

3/4 times 6/5

18/20 multiply numerators and denominators

you could also answer as 0.9

Answer:

y = -[tex]\frac{1}{3}[/tex] + 4

Step-by-step explanation:

first of all we know the slope of the equation which is 3x. then we know that we are supposed to write an equation that is perpendicular to y = 3x + 3. so since it is supposed to be perpendicular we have to make the current slope opposite.

so slope for our new equation will be -[tex]\frac{1}{3}[/tex]x.

now since we know our slope we use point-slope form and plug everything in.

point-slope form: y1-y=m(x1-x)

plug it in:

y - 2 = -[tex]\frac{1}{3}[/tex] (x - 6)

= y - 2 = -[tex]\frac{1}{3}[/tex]x +2

= y = -[tex]\frac{1}{3}[/tex] + 4

Marta has a better estimate

Step-by-step explanation:

cause let's round both one to the nearest ten. 260*30

then let's cancel both zeros to make it easier

26*3=78 and just add on two zeros at the end

clearly Marta estimate is better as it is closer to 7800

Answer:

28.3, 28 1/3, 25 1/4, 5v25

Step-by-step explanation:

Answer:

x=12

Triangle abc and Def are congruent but different sizes. The original triangle has side values of 2, 6 and 5. Then the shape is dilated by an unknown factor, giving it the side lengths of 4, x, and 10. Looking at the increase in side lengths we see that theres an increase of 2 to 4, or multiplying by 2 and an increase from 5 to 10, or multiplying by to. So now that we know there was a dilation of 2, we multiply 6 by 2 to find 12

Two number whose sum equal to - 8 are - 11 and 4.

We have to given that,

To find two numbers whose sum equal to - 8.

Now, Let us asume that,

Two numbers are - 11 and 4.

Sum of both numbers are,

- 11 + 4

= - 8

Hence, Two number whose sum equal to - 8 are - 11 and 4.
