An amount of 25,000 is borrow for 15 years at 5.5% interest, compounded annually. If the loan is paid in full at the end of that

Airida [17]

Answer: $55,811.91$

Step-by-step explanation:

Given

Principal amount is 25,000

Time Period is $t=15\ yr$

Rate of interest $r=5.5\%$

Amount in compound interest is given by

$\Rightarrow A=P\left(1+r\%\right)^t$

Insert the values

$\Rightarrow A=25,000(1+\dfrac{5.5}{100})^{15}\\\\\Rightarrow A=25,000(1.055)^{15}\\\Rightarrow A=55,811.91$

Therefore, $55,811.91$ must be paid back

Can I have some help, please?

Marianna [84]

Answer:

$-3(t+1)(8t-3)$

Step-by-step explanation:

First, factor both the denominators completely:

$9-24t\\= 3(3-8t)\\= 3(-8t+3)\\= -3(8t-3)$

$8t^2+5t-3\\= 8t^2+8t-3t-3\\= 8t(t+1)-3(t+1)\\= (8t-3)(t+1)$

Now, we can see that the factors of the first denominator are -3 and 8t-3.

The factors of the second denominator are t+1 and 8t-3.

To find the LCD, multiply all of these factors together:

$-3(t+1)(8t-3)$

Notice how we only multiply 8t-3 in the equation once. This is because it was present in both denominators, unlike the other factors.

I hope this helps!

1. A rabbit can hop 6 feet in 2 seconds and 12 feet in 4 seconds. If the number of feet varies directly with the time the rabbit

kykrilka [37]

Answer: The rabbit is hopping at 3 feet/ sec in speed

Step-by-step explanation:

Step 1

Let the The number of feet of the rabbit be expressed as N

AND time rabbit spends hopping can be expressed as t

From the question, The number of feet varies directly with the time rabbit spends hopping can be expressed as

N α t

Let us introduce a constant of proportionality ,S which represents speed in this case, we now have that

N = St

STEP 2 -- SOLVING

If the rabbit hop 6 feet in 2 seconds, Then speed =

N = St

6= S X2

S = 6/ 2

S = 3

also

If the rabbit hop 12 feet in 4 seconds, Then speed =

N = St

12= S X 4

S = 12/ 4

S = 3

Also recall

that Speed = Distance / time

Pluging the values in the first case,

speed = 6 feet/ 2 secconds = 3 feet/ seconds

in the second case

Speed= 12 feet/ 4 second s= 3 feet/ secs.

Dam naj za poprawną odp

Morgarella [4.7K]

Po pierwsze, należy dodać dwie frakcje razem na szczycie.

3 2/3 + 1 1/3 = 4 3/3 = 5

Teraz przychodzi do 5/2

Lub 2 1/2 jako liczba mieszanej.

Nawiasem mówiąc, użyłem Google Translate
