A loan of 43,000 is made of 4% interest, compounded annually. After how many years will the amount due reach $66,000 or more?

Answers

Answer:

10 yrs

Step-by-step explanation:

A=P(1+r/n)^nt, P=initial investment, r=annual interest rate,n=number of compounding periods per year, A=amount after t years

For given problem:

P=37000

r=5.5%=.055

n=1

A=62000

62000=37000(1+.055)^t

62/37=1.055^t

tlog(1.055)=log(62/37)

Using log keys on calculator:

t=log(62/37)/log(1.055)≈10 yrs

about 13 years

x>9/5

Step-by-step explanation:

2/3x-1/5>1

Solve like a regular equation.

2/3x-1/5>1 add 1/5 to both sides

2/3x>1/5+1

2/3x>6/5 divide by 2/3 on both sides

x> 9/5

Answer:

[tex]x>\frac{9}{5}[/tex]

Step-by-step explanation:

Start at 2/3x - 1/5 > 1

Add 1/5 to both sides :

2/3 x > 6/5

Multiply both sides by 3 :

2x > 18/5

Divide both sides by 2 :

x > 9/5

Using N as the center and any radius, draw an arc which intersects NM and NO. Label the interception points P and Q.
With a straightedge, connect points D and E.

Answers

Answer:

Step-by-step explanation:

using N as the center and the same radius as before, draw an arc that intersects NO .Label the arc PQ where Q intersects NO.

Congruent angles have the same measure.

The next step is (b) Using N as the center and the same radius as before, draw an arc that intersects NO. Label the arc PQ where Q intersects NO.

The attached image implies that you have already constructed a straight line NO.

The next step is to construct an arc that intersects line NO

To do this, we make use of the following steps

Measure the distance ABMeasure the distance BDConstruct an arc PQ of length BD using point N as the centerLabel the points of intersection as P and Q

Hence, the next step is (b)

Marcella purchased a car using a simple interest loan. The loan had an interest rate of 5.5% and was for 3 years. Marcella paid $231 in interest. The principal amount of the loan was for $_____ .

Answers

Answer:

Principal = $12600

Step-by-step explanation:

Simple Interest Formula

I = PRT

The formula for Principal Amount is:

I/RT = P

R = 5.5% = 0.055

T = 3

I = $231

P = 231 / 0.055 × 3

P =231/ 0.0183333333

P = $12600.000023

Approximately = $12600

Answer:

A) Lexi is 15 and Tanner is 18

B) Enrique has 24 magnets and Peter has 88 magnets

Step-by-step explanation:

t = 3 + l

t + l = 33

substitute:

(t) + l = 33

(3 + l) + l = 33

3 + 2l = 33

-3 -3

2l = 30

/2 /2

l = 15

Lexi is 15

solve for t:

t + 15 = 33

-15 -15

t = 18

Tanner is 18

e = p - 64

e + p = 112

substitute

(e) + p = 112

(p - 64) + p = 112

2p - 64 = 112

+ 64 +64

2p = 176

/2 /2

p = 88

Peter has 88 magnets

e + (p) = 112

e + 88 = 112

- 88 - 88

e = 24

Enrique has 24 magnets

A biologist recorded the population growth of two species of frogs in a pond area starting in 2010. The first species started with 42 frogs and increased by 6 frogs per year. The second species started with 30 frogs and increased by 8 frogs per year.

make an equation modeling equal populations of the frogs at T years after 2010.

Answers

Answer:

42 + 6t = 30 + 8t

Step-by-step explanation:

1st species starts with 42f. They gain 6 frogs a year, with the letter 't' representing years. 42 + 6t would be the rate for the first species. 2nd species starts with 30 and gains 8 frogs a year, the letter 't' also representing years. So 30 + 8t would be the rate. Writing an equation to find when the groups are equal, it would result in 42 + 6t = 30 + 8t

To find the answer to this,

42 + 6t = 30 + 8t

Step 1: Subtract 30 from both sides

42-30 +6t = 30-30 + 8t

12 + 6t = 8t

Step 2: subtract 6t from both sides

12 + 6t-6t = 8t-6t

12 = 2t

Step 3: divide both sides by 2

12/2 = 2t/2

6 = t

Step 4 : Rearrange

t = 6

Answer = 6
