After 5 years, Amanda's account earned $1500 in interest. If the interest rate (in decimal form) is 0.1, how much did Amanda initially
invest?

Answers

Amanda's starting capitalization is $3000.

Simple interest: What is it?

Simple interest tells us how much interest will be charged on a loan.

Simple Interest = Principal x Interest Rate x Time" is the written formula.

Principal, rate of interest, and period make up the basic interest formula.

Rate (in decimal) Equals 0.1, as stated.

5 years is time.

$5000 with simple interest

As a result, 1500 = p (0.1). (5)

1500/0.5 equals the principal value

Principal is 3000.

Consequently, the first outlay is $3000.

Express the relation below as a table. I’m confused some help would be nice

Answers

STEP-BY-STEP EXPLANATION

Given information

The following ordered pairs were provided in the question given

(11, -3)

(-20, 3)

(-17, 2)

Recall that, the general form of writing ordered pairs is (x, y)

Where,

x = input

y = output

For the above-ordered pairs

(11, -3) can be expressed as

x = 11 , and y = -3

(-20, 3)

x = -20, and y = 3

(-17, 2)

x = -17, and y = 2

The next step is to write the above-ordered pairs as a table

P(-9,-4) Q(-7,-1) whats is PQ

Answers

Step-by-step explanation:

I assume the question is about the distance between both points.

2 points in the coordinate grid create a right-angled triangle :

their direct connection (distance) is the Hypotenuse (the baseline, it is the side opposite of the 90° angle), and the x and y coordinate differences are the legs.

so, we can use Pythagoras to get the distance.

c² = a² + b²

c being the Hypotenuse, a and b being the legs.

so,

distance² = (-9 - -7)² + (-4 - -1)² = (-9 + 7)² + (-4 + 1)² =

= (-2)² + (-3)² = 4 + 9 = 13

distance = sqrt(13) = 3.605551275...

just in case, if you needed the line equation connecting these 2 points, I would assume the slope-intersect form

y = ax + b

"a" being the slope, "b" being the y-intersect (the y-value when x = 0).

the slope is always the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another.

using the 2 given points

x changes by +2 (from -9 to -7).

y charges by +3 (from -4 to -1).

the slope is

+3/+2 = 3/2

and our equation looks like

y = 3x/2 + b

now we use the coordinates of 1 point, e.g. (-7, -1), to get b

-1 = 3/2 × -7 + b = -21/2 + b

-1 + 21/2 = b

-2/2 + 21/2 = b

19/2 = b

our equation is then

y = 3x/2 + 19/2

or

y = (1/2)×(3x + 19)

(4 points)a. Step 1b. Step 2c. Step 3d. Step 4

Answers

Given:

m = 8 + 2n

4m = 4 + 4n

Let's follow the steps shown to find out the step with the error.

Step 1:

Multiply equation 1 by -4

-4(m) = -4(8 + 2n)

4m = 4 + 4n

Step 2:

-4m = -32 - 8n

4m = 4 + 4n

Step 3:

Use elimination method to simplify

-4m = -32 - 8n

4m = 4 + 4n

-4m + 4m = -32 + 4 -8n + 4n

This is where the student made the first error, because "4" was ommited.

This error led to subsequent errors in step 4 and 5

Step 4:

0 = -28 - 4n

Add 4n to both sides

0 + 4n = -28 - 4n + 4n

4n = -28

Step 5:

Divide both sides by 4

The measures of the unknown angles are as follows:

∠1 = 27∠2 = 97°∠3 = 56°∠4 = 27°∠5 = 56°

How to find the measures of angles?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles etc.

The parallel lines are line m and line l .  The parallel lines m and l are cut by two transversals.

Therefore, the measures of the unknown angles are as follows:

∠1 = 27°(vertically opposite angles)

∠1 = ∠4(alternate angles)

∠4 = 27°

Alternate angles are congruent. Vertically opposite angles are congruent.

Therefore,

∠1 + ∠2 = 124

27 + ∠2 = 124

∠2 = 124 - 27

∠2 = 97°

∠3 = 180 - ∠2 - ∠1 (sum of angles on a straight line)

∠3 = 180 -  97 - 27

∠3 = 56°

∠5 = 180 - ∠4 - ∠2

∠5 = 180 - 97 - 27

∠5 = 56°

Tyler wants to crate a scale drawing of his bedroom. His bedroom is a rectangle with length 5m and width 4m. He decides on a scale of 1 to 80.

Answers

The scale drawing with length 0.0625m and width 0.05m.

What is scale factor?

To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object.

When both the original dimensions and the new dimensions are known, the scale factor may be determined. When employing the scale factor, there are two terms that must be understood. When a figure's size is increased, we refer to this as scaling up, and when its size is decreased, we refer to this as scaling down.

Given:

length= 5m

width= 4m

and,

The scaled dimension = (Actual dimension) x (scale factor) ...(i)

scale factor =1/50

(1) The actual width = 4 m.

So, the width of the door on the scale drawing=  4x (1/80)= 0.05 m

(2)The actual length = 5 m.

So, the length of the door on the scale drawing=  5 x (1/80)= 0.0625 m

Hence, the scale drawing with length 0.0625m and width 0.05m.

your checking account is overdrawn by $120.22. you write a check for $80.25. what is the balance in your account???

Answers

The amount or balance left in the bank account is $39.97.

The amount of money held in a financial institution, such as a savings or checking account, at any particular time is known as the account balance. The net amount, which includes all debits and credits, is always the account balance.

The current balance in the bank account is $120.22.

The check was issued for $80.25.

Let x be the balance left in the account.

Then,

The balance left = Initial balance in the account - The amount for which the check was issued

x = Initial balance in the account - The amount for which the check was issued

x = $120.22 - $80.25

x = $39.97

Answer:

The slopes are the same and the y-intercepts are different.

Explanation:

Recall that the slope-intercept equation of a line is generally given as;

[tex]y=mx+b[/tex]

where;

m = slope of the line

b = y-intercept of the line

Let's go ahead and rewrite the first equation in slope-intercept form as seen below;

[tex]\begin{gathered} x+2y=8 \\ 2y=-x+8 \\ y=-\frac{1}{2}x+\frac{8}{2} \\ y=-\frac{1}{2}x+4 \end{gathered}[/tex]

We can see from the above that the slope(m) of the first equation is -1/2 and the y-intercept(b) is 4.

Let's go ahead and rewrite the second equation in slope-intercept form as seen below;

[tex]\begin{gathered} 2x+4y=12 \\ 4y=-2x+12 \\ y=-\frac{2}{4}x+\frac{12}{4} \\ y=-\frac{1}{2}x+3 \end{gathered}[/tex]

We can see from the above that the slope(m) of the second equation is -1/2 and the y-intercept(b) is 3.

We can see from the above that, for the two equations, the slopes are the same, and the y-intercepts are different.

Singer A and Singer B had the two top-grossing concert tours for a certain year, together generating $438 million in ticket sales. If Singer B took in $22 million less than Singer A, how much did each tour generate?

Answers

To answer this question, we have that both singers generated $438 million in tickets sales.

Then, we can rewrite it in algebraic expressions as follows:

[tex]A+B=438[/tex]

However, we know that singer B took in $22 million less than singer A:

[tex]B=A-22[/tex]

Now, we can substitute this expression in the original one as follows:

[tex]A+A-22=438[/tex]

And to solve this equation, we can add the like terms, and then add 22 to both sides of the equation as follows:

[tex]2A-22+22=438+22\Rightarrow2A=460\Rightarrow\frac{2A}{2}=\frac{460}{2}[/tex][tex]A=230[/tex]

Then, to find the earnings of singer B, we have:

[tex]A+B=438\Rightarrow B=438-A[/tex]

Then, B is equal to:

[tex]B=438-230\Rightarrow B=208[/tex]

Then, we can check that A + B is:

[tex]A+B=230+208=438[/tex]

And we can see that singer B took in $22 million less than singer A:

[tex]B=230-22=208[/tex]

In summary, therefore, we can say that each tour generated:

Singer A generated $230 million in ticket sales and Singer B generated $208 million.
