Answer:

19 years approx

Step-by-step explanation:

Given dta

P= $9000

r= 6.5%

A= $31100

Calculate time, solve for t

t = ln(A/P) / r

substitute

t= ln(31100/9000)/0.06.5

t= ln(3.45)/0.06.5

t= 1.23/ 0.065

t= 18.92

Hence the time is 19 years approx

Answer:

Step-by-step explanation: The first one would be -40 X 30. The parentheses around -25 turns it into a positive. And 5 make you round up

For 2, the -18 turns into a positive 18 bc of the parentheses. So round up to 20. Round 38 up to 40. 20 x 40

For 3, the negative 16 turns positive, making the equation -21 x 9 x 16. Round them to -20, 10, and 20. The equation is -20 x 10 x 20. Hope this helps!

Answer:

The intrest rate is 8% and after 7 years she will have made 149.90 in total intrest.

Answer:

y=-x+5

Step-by-step explanation:

For this question, we have to use point-slope form:

y-y1=m(x-x1)

y-1=-(x-4)

y-1=-x+4

y=-x+5

Answer:

C. 49.

Step-by-step explanation:

The measure of the angle below <1 = 68 degrees (vertical angles).

m < 3 = 72 + 68         External angle of a triangle theorem.

m < 3 = 140

3x - 7 = 140

3x = 147

x = 49.

Answer:

C

Step-by-step explanation:

The angle at the top of the triangle is vertical to ∠ 1 and congruent

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 3 is an exterior angle of the triangle, then

3x - 7 = 72 + 68 = 140 ( add 7 to both sides )

3x = 147 ( divide both sides by 3 )

x = 49 → C

Step-by-step explanation:

Hello,

First, there are 8 possible outcomes for the game spinner.

Second, the spinner is on 5, meaning that the outcome is 5.

Try to work with this, and if you need more help, I’ll answer back if I can.

Answer:

okay see the correct answer is D

Step-by-step explanation:

first 0f all a sample space means the possible outcome for all possibilities. like just as shown in the spinner the 1 2 3 4 5 6 7 8, or it could be in a dice 1 2 3 4 5 6 like that

second of all the outcome shown is wh,at the possibility landed on like as shown its five since the arrow of the spinner is there, as for a dice for example it could have been 4 4 since dice are always 2

I SERIOUSLY AM SKIPPING MY MATH CLASS IM HELLA BORED BUT DO U UNDERSTAND MATE

Answer:

Let's solve for x.

4x+5y=7

Step 1: Add -5y to both sides.

4x+5y+−5y=7+−5y

4x=−5y+7

Step 2: Divide both sides by 4.

4x/4=−5y+7/4

x=−5/4 y+ 7/4

Answer: for the first one x=−5/4 y+ 7/4

3x−2y=−12

Step 1: Add 2y to both sides.

3x−2y+2y=−12+2y

3x=2y−12

Step 2: Divide both sides by 3.

3x/3=2y−12/3

x=2/3y−4

Answer:

x=2/3y−4

Step-by-step explanation:

Answer:

1 and 8 alternate exterior angles

4 and 5 - alternate interior angles

6 and 7 - vertical angles

4 and 8 - corresponding angles

3 and 5 - consecutive interior angles

1 and 2 - linear pair

Answer:

-9x² + 5x + 11

Step-by-step explanation:

-5x² + (-4x²) + 5x + 2 + 9

-9x² + 5x + 11

Answer:

t = -3.5

Step-by-step explanation:

4t + 5 = -9

4t = -14

t = -3.5

Answer:

t=1

Step-by-step explanation:

subtract 5 from both sides then simplify and divide

Answer:

25

Step-by-step explanation:

12+13=25 so 25x5=125 and 125 divide 5=25

I'm on computer so examples will look weird so I will label them.

Answer:

Your answer will be 25.

Step-by-step explanation:

1. You will rewrite the division as a fraction

Ex:    5 × (12+13)

     ____________

               5

2. Cancel the common factor which is 5 so you will cross out the 5's

3. Then you would divide the (12+13) by 1

4. Finally you would add the 12 and the 13 to get 15.

I hope this helps.   :  )

C

Step-by-step explanation:

64/250 is 25% which translates to .25

The rule for coordinates for a reflection over the y -axis is:

( x, y ) → ( −x, y )

The coordinates plane for the triangle ABC after a reflection over the y-axis is

A(5, -2), B(4, -4), and C(6, -4).

Reflection is a transformation that flips a shape in a mirror line also called a line of reflection so that each point is the same distance from the mirror line as its reflected point.

The rule for coordinates for a reflection over the y -axis is:

( x, y ) → ( −x, y )

We have,

The following coordinates:

A = (-5, -2)

B = (-4, -4)

C = (-6, -4)

Since the rule for coordinates for a reflection over the y-axis is

(x, y) ⇒ (-x, y)

We have,

(-5, -2) = (5, -2)

(-4, -4) = (4, -4)

(-6, -4) = (6, -4)

Thus the coordinates plane for the triangle ABC after a reflection over the y-axis is A(5, -2), B(4, -4), and C(6, -4).
