Hunter-Best [27]

Answer:

See Explanation

Step-by-step explanation:

Required

Use any 4 consecutive digit from 0 to 9 to form an expression that equals 1 through 30

There is no formula to answer this question. All we need to do is, apply trial by error method to for each expression.

Possible expression and their results are:

- 1  + 2 * 3 - 4 = 1

1 + 2 + 3 - 4 = 2

0 * 3 + 1 + 2 = 3

0 * 2 + 1 + 3 = 4

1 * 3 + 4 - 2 =5

0 + 1 + 2 + 3 = 6

0 + 1 + 2 * 3 = 7

3 + 4 - 5 + 6 = 8

1 * 2 + 3 + 4 =9

1 + 2 + 3 + 4 =10

2^3 + 4 - 1 = 11

5 + 6 - 7 + 8  =12

4^2 - 3 * 1 = 13

2 + 3 + 4 +5=14

2 * 3 +4 + 5 = 15

4 * (3 - 1)^2 = 16

3 * 5 + 4/2 = 17

3 + 4 + 5 + 6 = 18

2 + 3 * 4 + 5 = 19

3 + 2^4 + 1 = 20

4 * 5 - 6 + 7 = 21

4 + 5 + 6 + 7 =22

3 * 4 + 5 + 6 = 23

5^2 -4 + 3 = 24

2^5 - 4 - 3 = 25

5 + 6 + 7 +8 = 26

\frac{3^4}{5-2} =27

5 * 4 + 2^3 = 28

3 + 4 * 5 + 6 = 29

6 + 7 + 8 +9 = 30

Lilian has part of $9000 invested at 4% and the remainder at 6%. His annual return on each investment is the same. At what rate
Debora [2.8K]
Given:
Total amount invested = $9,000
interest rates = 4% and 6%

Let x be the part of 9,000.
Note that annual return on each investment is the same.

0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540 
x = 540/0.10
x = 5,400

0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216

total interest for the year : 216 + 216 = 432

Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate

Interest rate would be 4.8% to get the same interest from the whole 9,000.

Using -2, -1, 0, 1 and 2 as your x values solve x+ 1/2y =1; then graph it
Anon25 [30]
X + y/2 = 1
y/2 = 1 - x
y = 2(1 - x)
y = 2 - 2x

when x = -2
y = 2 + 4
y = 6
(-2,6)

when x = -1
y = 2 + 2
y = 4
(-1,4)

when x = 0
y = 2 - 0
y = 2
(0,2)

when x = 1
y = 2 - 2
y = 0
(1,0)

when x = 2
y = 2 - 4
y = -2
(2,-2)
