Answer:

11 years approx

Step-by-step explanation:

Given data

P=$1000

A=2000

R=6.5%

T= ?

Calculate time, solve for t

t = ln(A/P) / r

substitute

t=ln(2000/1000)/0.065

t=ln(2)/0.065

t=0.693/0.065

t=10.66

Hence the time is 11 years approx

In two hours Holden completed 3/4 of his race how long will it take Holden to complete the entire race?

vivado [14]

Answer:

$\frac{1}{4}$ = 50 Minutes

Whole Race Time : 2 Hour and 50 Minutes

Step-by-step explanation:

so 2 Hour = $\frac{3}{4}$ Race completed

we need to find what 1/4 Race = x Hours

so 200 divided by 4 because $\frac{3}{4}$ Race is done.

we need to find how long to finish the whole race also known as $\frac{4}{4}$ .

200 divided by 4 = 50

so Holden still need 50 Minutes to finish the race.

X = -1!
1. Factor out 2 from the expression : 2(x-5) / 4 = 3x
2. Reduce the fraction with 2 : x-5 / 2 = 3x
3. Multiply both sides of the equation by 2 : x-5=6x
4. Move the terms : x - 6x = 5
5. Collect like terms : -5x = 5
6. Divid both sides by -5
Hope this helps!

How do you rearrange fractions

almond37 [142]

For ex:

U have 4/8 - 6/2 u would probably have to use KCF- Keep Change Flip
So then it’ll be 4/8 + 2/6
U kept the 4/8 then u changed the subtraction to addition and u flipped the 2 to the numerator and the 6 denominator.
Idk my dude this is what I can think of

Write an algebraic expression to represents the verbal expression: the difference between the product of 4 and a number and the

Naily [24]

Answer:

$4n-n^2$

Step-by-step explanation:

I use 'n' as the unknown value, but you can use any letter you want as the variable.

The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.

The square of the number would be n². Squaring a number is multiplying a number by itself.

The phrase 'difference between...' means subtraction.

Putting it together:

"The difference between the product of 4 and a number and the square of the number" would be:

$4n-n^2$

Hope this helps.
