Answer:

Jeez this is a big question

Step-by-step explanation:

1. if they are rounded to the nearest 10 that would mean that it is actually

40 * 40

40 * 40 is 1600. The answer for #1 is 1600

2. its just asking what 21 x3 is, 21x3 is 63

3. All you do for this is 20*23

20 * 23 is 460

4. 42 * 31 is 1302

5. 22 * 95 = 2090

6. You do 20x2 which is 40 and then you do 8x2 which is 16

Adding

then you have 40 + 16 = 56

Subtracting

40 - 16 = 24

Multiplying

40 * 16 = 640

Dividing

40/16 = 2.5

7. 33x2 is 66

8. 57* 4 is 228

9. 128 * 11 is 1408 but if you round the 11 to the nearest 10, that would be 10, then if you round the 128 to the nearest 10, that would be 130, and then 130 * 10 is 1300

The future value of $1,000 invested at 8% compounded semiannually for five years is \bold{\$ 1,480}

<u>Solution:</u>

\bold{A = P (1 + i )^{n}} ----------- equation 1

A = future value  

P= principal amount  

i = interest rate

n = number of times money is compounded  

P = 1000

i = 8 %

\mathrm{n} = \text { compounding period } \times \text {number of years}

(Compounding period for semi annually = 2)

\mathrm{n} = \text { compounding period } \times \text {number of years}

Dividing “i” by compounding period

i = \frac{8 \%}{2} = 0.04

Solving for future value using equation 1

\begin{array}{l}{A = 1000(1 + 0.04)^{10}} \\\\ {=1000 (1.04)^{10}}\end{array}

= 1480.2

\approx 1,480 \$

Sav [38]
S = sally C = Chris J = Joe
sally is one year older than 3 times the age of joe, so
s = 3j + 1
chris is 5 years younger than 6 times the age of jo, so
c = 6j - 5
sally and chris are the same age so
s = c so
3j + 1 = 6j - 5
-3j -3j
1 = 3j - 5
+5 +5
6 = 3j or
3j = 6
3j/3 = 6/3
j = 2

check
s = c
3(2) +1 = 6(2) - 5
6 + 1 = 12 - 5
