Draw a quadrilateral that does not belong then explain why

If a tank holds 4500 gallons of water, which drains from the bottom of the tank in 50 minutes, then Toricelli's Law gives the vo

nordsb [41]

Answer:

t = 0

Before it starts rushing that's when it will be fastest

Step-by-step explanation:

For the water ib the tank to flow very fast it means that there is a big volume of water present.

And for volume of water to be present that much it means that the water must

have not leaked much or at all.

And for that it signifies large volume of water.

If we do the calculation we'd see that time will be actually equal to zero for the pressure and the volume of the water to be biggest.

V = 4500 (1 − 1 /50 t )^2

V = 4500

4500 = 4500(1- 1/50t)²

1 = 1- 1/50t

0 = -1/50t

t = 0

Andrei [34K]

Answer:

X<2

Step-by-step explanation:

2x+4<8

subtract 4 from both sides

2x+4-4<8-4

simplify

2x<4

divide both by 2

2x/2<4/2

Raj wakes up in the morning and notices that his digital clock reads 07 2(A)5(B).After noon, he looks at the clock again.what is

Gre4nikov [31]

Answer:

i. $P(A) = \frac{1}{10}$

ii. $P(B) = \frac{1}{10}$

iii. $P(A) = \frac{3}{5}$

iv. $P(B) = \frac{2}{5}$

Step-by-step explanation:

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

$A = \{4\}$

$n(A) = 1$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{1}{10}$

Calculating (b)

First, we need to list out the possible sample space, S of B

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

$B = \{8\}$

$n(B) = 1$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{1}{10}$

Calculating (c)

Using the sample space in (a)

$n(S) = 10$

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

$A = \{0,1,2,3,4,5\}$

$n(A) = 6$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{6}{10}$

$P(A) = \frac{3}{5}$

Calculating (d)

Using the sample space in (b)

$n(S) = 10$

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

$B = \{6,7,8,9\}$

$n(B) = 4$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{4}{10}$

$P(B) = \frac{2}{5}$

You deposit the same $10,000 into a bank account at 4% annual interest. How long will it take for the $10,000 to compound to $30

Readme [11.4K]

Answer:

time = 28 years

Step-by-step explanation:

Given,

principal amount = $10,000

rate = 4%

total amount = $30,000

According to compound interest formula

$A\ =\ P(1+r)^t$

where, A = total amount

P = principal amount

r = rate

t = time in years

so, from the question we can write,

$30000\ =\ 10000(1+0.04)^t$

$=>\ \dfrac{30000}{10000}\ =\ (1+0.04)^t$

$=>\ 3\ =\ (1.04)^t$

by taking log on both sides, we will get

=> log3 = t.log(1.04)

$=>\ t\ =\ \dfrac{log3}{log1.04}$

=> t = 28.01

So, the time taken to get the amount from 10000 to 30000 is 28 years.
