How to write unit form for (2 tens 1 one) x 10

Mathematics
1 answer:
poizon [28]3 years ago
3 0
Numbers are arranged by their place values. Place values give a quantity of value to a certain digit in a number. Given a number, the rightmost number is the ones place, followed by the tens place, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, hundred millions, as so on and so forth. The place value of a certain digit is 10 times bigger than its adjacent digit to the right.

So for this problem, all you have to do is multiply the number of units of each place value, then multiple them all by 10.

(2(10) + 1(1))×10
21 × 10 = 210

Therefore, the number is equivalent and written as 210.

A. Factor 28 + 7g  7(g <span>+ 4) 

add 
28 </span><span>+ 7g 

= 7 (g </span>+ 4)

B. (12r + 15) – 65 Remove parentheses
12r+15-65

= 12r - 50 

C. 24 – (8p – 12)

24 - (8p - 12) = -8p + 36 

24 - (8p - 12)  -(8p - 12) 8p + 12

= 24-8p+12

Simplify 24-8p+12 

Group like terms
-8p+12+24

Add the numbers  12+24=36

Answer is -8p+36

A person borrows $2500 and they must pay this amount back, plus the $125 in simple interest. In total, they must pay back 2500+125 = 2625 dollars.

Divide this amount over 6 months
2625/6 = 437.50

The monthly payment is $437.50, so the answer is choice B

Answer correctly please
Paul [167]

Answer:

\$272,49

Step-by-step explanation:

7. \displaystyle /text{The answer makes sense because since the depreciation rate is 15%, we know that we need to use the "exponential decay" formula.}

6. \displaystyle /text{After a depreciation rate of 15% for the past 8 years, the stock is now worth approximately $272,49.}

5. \displaystyle 1000[0,85]^8 = 272,490525 ≈ \$272,49

4. \displaystyle 1000 = a \\ -15\% + 100\% = 1 - r; 85\% = 1 - r \\ 8\:years = time\:[t]

3. \displaystyle /text{We need to use the "Exponential Decay" formula} - f(t) = a[1 - r]^t, where a > 0

2. \displaystyle /text{How much is the stock worth after a depreciation rate of 15% per year?}

1. \displaystyle /text{initial amount: $1000, a depreciation rate of 15%, and a time period of 8 years}

I am joyous to assist you anytime.
