1) James deposited $4,000 into an account. He made
no additional deposits or withdrawals. James earned
5.75% annual simple interest on the money in the
account.
What was the balance in dollars and cents in James
account at the end of 5 years?

Answers

Answer:

$5150

Step-by-step explanation:

Given data

Principal=$4000

Rate=5.75%

Time= 5 years

The expression for the balance on  simple interest is

A=P(1+rt)

substitute

A=4000(1+0.0575*5)

A=4000(1+0.2875)

A=4000X(1.2875)

A=$5150

Hence the  balance is $5150

3) -23

4) 8

5) 7

6) -64

7) -10

8) 19

9) 9

10) -56

Answer:

1) = -4

2) = 5

3) = 17

4) = 8

5) = 7

6) = -64

7) = -10

8) = 19

9) = 9

10) = -56

Step-by-step explanation:

1) (-4 + 2)^2 = -2^2 = -4

2) 25 / (9 - 4) = 25 / 5 = 5

3) 4 * 5 - 3 = 20 - 3 = 17

4) 2(2 + 2) = 2 * 4 = 8

5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7

6) (-3 - 1)^3 = -4^3 = -64

7) 5(5 - 7) = 5 * -2 = -10

8) 2 * 7 + 5 = 14 + 5 = 19

9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9

10) 8(-1 - 6) = 8 * -7 = -56

After a shipwreck, Sam is stranded on a desert island. He needs to build a shelter, so he
makes an axe using materials from the wreckage and starts cutting down trees.
There is a proportional relationship between the number of days Sam is stranded on the
island, x, and the total number of trees he cuts downy

Answers

The constant of proportionality  is gotten from the graph to be 5

How to solve for constant of proportionality

The complete part of the question is in the attached image which is a graph.

The graph has a positive slope, which implies a direct proportionality

hence we have that the number of trees is directly proportional to the number of days spent.

Let t represent the number of tress, d represent the number of days, and k constant of proportionality

The relationship is expressed mathematically as:

t d

t = kd

using any arbitrary point from the y axis ( t ) and tracing to the x axis ( d ). We have t = 5 and d = 1. substituting the values gives

5 = k* 1

Therefore

k = 5

The constant of proportionality is 5

{45x+6y=15-x+18y=11 is..........................

Answers

Answer:

Step-by-step explanation:

45x+6y=15

-x+18y = 11

let's use elimination, the other way is by substitution,  either way works but, it looks to me like elimination would be easy with the  'y'

3(45x+6y=15)

135x + 18y = 45 ( subtract  2nd eq.  from 1st )

-( -x+18y = 11 )

136x +0y =34

x = 34 /136

x = 1 /4

there is X

plug that back into either of the 1st or 2nd equations to solve for y

- 1/4 + 18 y = 11

18y = 11 1/4

18y = 45/4

y = 45/4 *  1/18

y = 45/ 72

What is m angle B in degrees?
A. 30°
B. 45°
C. 60°
D. There is not enough information to determine.

Answers

Answer:

C

Step-by-step explanation:

The degrees of a triangle add up to 180.

Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.

Angle A is equal to sinA=1/2.

sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.

90-30=60.

That leaves you with 60 degrees for angle B.

Hello There!

When dilating a point we divide or multiply the coordinates by whatever the scale factor is

Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2

Preimage coordinates - ( -3 , 2 )
