2/5 is .4 as a fraction

prohojiy [21]2 years ago

4 0

Answer:

4/10 = 2/5

Step-by-step explanation:

To change the decimal .4 into a fraction, we can put the 4 over 10 because the 4 is in the tenths place. Right now, we have 4/10. We can reduce this fraction (by dividing the numerator and denominator by 2) to 2/5.

I hope this helped and please mark me as brainliest!

Suppose that you borrow $13,000 for three years at 5% toward the purchase of a car. Use <img src="https://tex.z-dn.net/?f=PMT%

Neko [114]

Answer:

PMT is 389.62

Total interest for the loan is $ 1026.32

Step-by-step explanation:

Given formula of monthly payment,

$PMT=\frac{P(\frac{r}{n})}{1-(1+\frac{r}{n})^{-nt}}$

Where,

P = Present value of the loan,

r = annual rate of interest,

n = number of months in a year,

t = number of years,

Here, P = $13,000, n = 12 months, r = 5% = 0.05, and t = 3 years,

Hence, the monthly payment,

$PMT=\frac{13000\times \frac{0.05}{12}}{1-(1+\frac{0.05}{12})^{-36}}$

≈ 389.62,

Therefore,

The amount of total interest paid = PMT × nt - P

= 389.62 × 36 - 13000

= 14026.32 - 13000

= $ 1026.32

A disk cost $3 more than a tape. rolex bought five disks and two tapes. The total cost was $120. what was the price of a disk?

Daniel [21]

First, I would organize your information into equations. So, the first sentence would be:

d = 3 + t d = disk and t = tape

Second and third sentence would be the equation:

5 d + 2 t = $120

To find the price of the disk, you would follow these steps.

5 (3 + t) + 2 t = 120 substitute d, with the equation that has a total, for

(3 + 2), then solve for t

15 + 5 t + 2 t = 120 distribute

15 + 7 t = 120 add like terms

7 t = 105 subtract from both sides

t = 15 divide from both sides

Then you substitute 15 in the first equation.

d = 3 + t substitute

d = 3 + 15 add

d = 18

So, d = 18 and t = 15. To check this, you just need to substitute the right variables.

1) 18 = 3 + 15

18 = 18

2) 5 (18) + 2 (15) = 120

90 + 30 = 120

120 = 120

When checking, we can see that the correct answer is $18 for the price of the disk.
