Salvador’s investment of $2,200 in the stock market earned $528 in two years. Find the simple interest rate for this investment.

Answers

Answer 1

Answer:

24%

Step-by-step explanation:

Step one:

given data

Principal= $2,200

SImple interest =$528

Time = 2years

Rate = ?

Required:

Rate R

The simple interest is expressed mathematically as

SI=PRT/100

substitute we have

528=2200*R*2/100

cross multiply

528*100=2200R

divide both sides by 2200

R=52800/2200

R=24%

Kim creates a model of a building. The scale of her model building is 1 foot to 8 inch. Some of the measurements are shown in the table. 11 Enter numbers in the empty boxes to correctly complete the table. ​

Answers

Answer:

Left

50 feet

Right

16 inches

10 inches

Step-by-step explanation:

Here, we want to make a conversion and fill in the empty spaces

The scale is 1 foot is 1/8 inch

To convert from foot to inch, we multiply by 1/8

To convert from inch to foot, we multiply by 8

Thus, we have ;

Let’s fill in the left spaces first;

6.25 * 8 = 50 feet

Right spaces, top to bottom;

128 * 1/8 = 16 inches

80 * 1/8 = 10 inches

A carpenter charges $45 for every 50 feet of fence he builds plus a travel charge of $37.50. If the equation, C = 4550F + 37.5 , can be used to determine the total cost, C, of building F feet of fence, how many feet of fence can be built for a cost of $352.50?

Answers

Answer:

Step-by-step explanation:

Given the total cost of the building expressed as;

C = 4550F + 37.5

C is the total cost

F is the length of the fence

Given

C = $352.50

Required

The length of the fence F

Substitute into the formula;

C = 4550F + 37.5

$352.50 =  4550F + 37.5

4550F = 352.50 - 36.5

4550F =  316

F = 316/4550

F = 0.0695 feet

hence 0.0695 feet of fence will cost $352.50

3) A product is marked down 15%; the sale price is $127.46. What was the
original price?

Answers

Answer:elling price (S.P)  =  (100 - m)% ⋅ Original price -----(1)

Here,  

S.P  =  127.46,  m  =  15

Substitute 127.46 for S.P and 15 for m in (1).

127.46  =  (100 - 15)% ⋅ Original price

127.46  =  85% ⋅ Original price

127.46  =  0.85 ⋅ Original price

127.46 / 0.85  =  Original price

149.95  =  Original price

So, the original price is $ 149.95.

Step-by-step explanation:

The original price of product when the product is market down by 15% and the sales price is given so it is $149.95.

Calculation of price:

Price is down by 15%, so m = 15% or 0.15.

So, Original price = [tex]\frac{Selling price}{( 1 - m)}[/tex]

By putting the value, we get

Original price = [tex]\frac{127.46}{(1 - 0.15)}[/tex]

= [tex]\frac{127.46}{0.85}[/tex]

= $149.95

Hence the original price of of the product was $149.95

Triangular numbers can be represented with equilateral triangles formed by dots the first fire triangle numbers are 1 3 6 10 and 15 is there a direct variation between a triangle number and its position in the sequence explain your reasoning

Answers

Answer:

There's no direct variation

Step-by-step explanation:

Required

Determine if there's a direct variation between the number and its position

I'll start by giving an illustration of how the triangle is represented using stars (*)

*

**

***

****

*****

Represent the line number with y and it's position with x

On line 1:

y = 1, x = 1

On line 2:

y = 2, x = 3

On line 3:

y = 3, x = 6

On line 4:

y = 4, x = 10

On line 5:

y = 5, x = 15

Note that, x is gotten by calculating the accumulated number of stars while y is the line number.

Direct variation is represented by

y = kx

Or

kx = y

Where k is the constant of variation

For line 1:

Substitute 1 for y and 1 for x

k * 1 = 1

k = 1

For line 2:

Substitute 2 for y and 3 for x

k * 3 = 2

Divide through by 3

k = ⅔

Note that the values of k in both computations differ.

This implies that there's no direct variation and there's no need to check further.

Answer:
No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and it's position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.

What is an equation of the line that passes through the point (6, 1) and is
perpendicular to the line 2x + 3y = 18?

Answers

Answer: y=1,5x-8

Step-by-step explanation:

At first transform the equation

2x+3y=18

3y= 18-2x

y= 6 - (2/3)x

The linear function has general form, which looks like that:

y=mx+n

perpendicular means that m1*m2=-1

In our case m1= -(2/3) and m2 is unknown

(-2/3)*m2= -1

m2=3/2 so m2=1,5

The line has to go through the point (6,1)

so 1=6*1,5+n

1=9+n

n= -8

so the function looks like that y=1,5x-8

Point A is located at -4.5, and point B is 3.25 units from point A. Write two additional equations that could be used to determine the location of point B.

Answers

Answer:

The equations are B = -4.5 + 3.25 and B = -4.5 - 3.25

Step-by-step explanation:

Since point A is located at -4.5 and point B is 3.25 units away from A, point B can either be located on the left or on the right of point A.

If point B is located at the right of A, the equation for point B is -4.5 + 3.25.

If point B is located at the left of A, the equation for point B is -4.5 - 3.25.

So, the equations are B = -4.5 + 3.25 and B = -4.5 - 3.25

Solve the system of linear equations using multiplication. - 3x + 2y 5x - 3y = 17 The solution is​

Answers

This is what i got X= 17/2 + Y/2

Answer:

Required Answer:-

Given:

5x - 3y = 2

3x - 2y = 4

To Find:

The values of x and y.

Solution:

We have,

→ 5x - 3y = 2 – (i)  

→ 3x - 2y = 4 – (ii)  

Multiplying equation (i) by 2, we get,  

→ 10x - 6y = 4 – (iii)

Multiplying equation (ii) by 3, we get,  

→ 9x - 6y = 12 – (iv)

Subtracting (iii) from (iv), we get,  

→ -x = 8  

→ x = -8  

Now, from (i),

→ 5 × (-8) - 3y = 2

→ -40 - 2 = 3y

→ -42 = 3y

→ y = -14  

So,  

→ (x, y) = (-8, -14)

Answer:

(x, y) = (-8, -14)

Five number summary

min = 5Q1 = 7median = 9Q3 = 12max = 15

===============================================

Explanation:

The given list of values is {6, 11, 13, 8, 15, 9, 11, 5, 9}

It sorts to {5, 6, 8, 9, 9, 11, 11, 13, 15}

The middle most value is the second 9. We have four items below or at the median {5,6,8,9} and four values above the median {11,11,13,15}

The middle item of {5,6,8,9} is (6+8)/2 = 14/2 = 7. This is the value of Q1.

The middle item of {11,11,13,15} is (11+13)/2 = 24/2 = 12. This is Q3.

The min is 5 since it is the smallest of the original list.

The max is 15 because it is the largest of the original list.

The five number summary is

min = 5Q1 = 7median = 9Q3 = 12max = 15

The boxplot that matches with this five number summary is the boxplot in the upper right corner.

The min is the left whisker. The max is the right whisker.

Answers

Answer: y= -1/1x - 1

Okay, to find the equation you must find the y-intercept and the slope.

To find the y-intercept, you must find (0,y). This is the point on the y-axis where x is 0. So, where along the y-axis is there a point? There is a point at (0,-1). Therefore, your y-intercept is -1.

To find the slope, you must do rise/run. Go to a point on the line, such as (0,-1). You must go up (or down) until you get lined up with next point on the line. You go up one time. Then, you must go right (or left) to get to the exact point. In this case, the point would be (-1,0). You go left one time.

If you go down or left when doing rise/run, the number would be negative. Since you went left, that number would be negative.

So, our slope would be 1/-1, which can also be written as -1/1.

Now, write the equation. There is always an x next to the slope. y= -1/1x

Then, put the y-intercept next to it. If it is positive, use a +. If it is negative, use a -. It is negative.

Therefore, the answer is y= -1/1x -1.
