190 divided by 2 over 3

1 answer:

6 0

Answer is 285
Reason
When you divide by a fraction, you flip the fraction and multiply
So 190 divided by 2/3 becomes 190 x 3/2
Factor 190 x 3/2, multiply across
190 x 3 = 570 then
570 divided by 2 = 285

tensa zangetsu [6.8K]

For the answer to the question above,
For<span> a) Mean time required for the entire process = (40+25) = 65 minutes
b) Variance time required for the entire process = (2^2+1^2) = 5 minutes
Standard deviation time required for the entire process = sqrt(5) = 2.236 minute.
I hope my answer helped you

Sean tried to drink as fast as he could. He drank the slushy at a constant rate. There were originally 275 milliliters of slushy

loris [4]

a. Sean drank at a rate of 5 milliliters per second.

b. It took Sean 55 s to drink all the slushy.

<h3>a. How to find the rate at which Sean drank?</h3>

Since Sean darnak at a constant rate and originally there were 275 milliliters of slushy in the cup. After 13 seconds, 210 milliliters of slushy remained.

The rate at which Sean drank, r = Change in volume of slushy/time for change

= (275 mL - 210 mL)/13 s

= 65 mL/13 s

= 5 mL/s

So, Sean drank at a rate of 5 milliliters per second.

<h3>b. How long did it take Sean to drink all the slushy?</h3>

The time it takes Sean to drink all the slushy is given by

T = V/r where

V = total volume of slushy = 275 milliliters and
r = rate of drinking by Sean = 5 mL/s

So, T = V/r

= 275 mL/5 mL/s

= 55 s

So, it took Sean 55 s to drink all the slushy.

What is the sum of the first eight terms of the series?

Ray Of Light [21]

Observe that as the series progresses, the term decreases by 1/4. To show this, observe the first four terms of the series below.

-200 = (1/4)(-800)
-50 = (1/4)(-200)
-12.5 = (1/4)(-50)

Since we have a common ratio, r, of 1/4, we can use the properties of a geometric series to find the 8th term of the series.

Recall that to find the sum of the nth term of a geometric series, we have

$S_{n} = a(\frac{1-r^{n}}{1-r})$

where a is the first term of the series and r is the ratio.

So, for the first eight terms, we have

$S_{8} = -800(\frac{1-(\frac{1}{4})^8}{1- \frac{1}{4}})$
$S_{8} \approx -1066.65$

Therefore, the sum of the 8th series is approximately -1066.65.

Answer: -1066.65

Which property states that if a = b and b = c, then a = c?

Step2247 [10]

Transitive.

Associative is (a + b) + c = a + (b + c)

Commutative is a + b = b + a

Reflexive is a = a

Thus, transitive is the correct answer.

Hope this helps!
