X^2 = 150
√x^2 = √150
x = 5√6 (or) ≈12.25

If a boat depreciates in value according to the simple interest formula Y=20,000(.92)^2 find the rate of decay. Write as a perce

Alexandra [31]

Answer:

Rate of Decay = 8%

Step-by-step explanation:

The decay formula is:

$F=P(1-r)^t$

Where F is the final value (here, it is given as "Y")

P is the initial value (here, given as 20,000)

r is the rate of decay (what we need to find)

t is the time (given as 2)

Comparing both the equations:

$F=P(1-r)^t\\Y=20,000(0.92)^2$

We see that:

1 - r =0.92

We solve for "r":

1 - 0.92 = r

0.08 = r

The rate of decay is 0.08, as a percentage, we need to multiply by 100, so we have:

0.08 * 100 = 8%

Rate of Decay = 8%

Which expression is equivalent to 4 over 9 (2n - 3)

AlexFokin [52]

Answer:

The result for this equation is $\frac{8}{9}n - \frac{4}{3}$ .

Step-by-step explanation:

-Solve:

$\frac{4}{9} (2n-3)$

-Multiply $2n$ and $-3$ by $\frac{4}{9}$ :

$\frac{8}{9} + \frac{-12}{9}$

-Reduce $\frac{-12}{9}$ to the lowest term by extracting and canceling out 3:

$\frac{8}{9}n - \frac{4}{3}$

-So, the result is $\frac{8}{9}n - \frac{4}{3}$ .

Kaya devoted 2/5 of her study time to mathematics, 3/20 of her time to social studies, 1/3 of her time to chemistry and the rema

andrezito [222]

Answer:

54 minutes

Step-by-step explanation:

The sum of fractions is ...

2/5 + 3/20 + 1/3 = 11/20 +1/3 = (3·11 + 20·1)/(20·3) = 53/60

Then the 42 minutes devoted to English represents 1 - 53/60 = 7/60 of her study time.

Kaya's social studies time is 3/20 = 9/60 of her total, so the ratio of SS to Eng is ...

SS : Eng = (9/60) : (7/60) = 9 : 7

When we multiply the numbers in this ratio by 6, we find ...

SS : Eng = 54 : 42

Kaya spent 54 minutes studying social studies.

What is a fraction of a fraction

Vikentia [17]

<h3> - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - </h3>

➷ When it comes to dividing fractions, there is a rule you must now.

It's called Keep Flip Change.

I'll give you an example:

$\frac{2}{7} / \frac{4}{6}$

Keep the first fraction exactly as it is

Flip the second fraction upside down (switch the numerator and denominator around)

Change the sign to a multiplication.

This is how it should look:

$\frac{2}{7} *\frac{6}{4}$

Now you just multiply them as you normally would to get an answer of:

$\frac{12}{28}$

➶Hope This Helps You!

➶Good Luck :)

➶Have A Great Day ^-^
