Robin invested $1000 in a 12% simple interest savings deposit for 3
years. He also invested an equal amount in a 10% compound interest
savings deposit for 3 years. At the end of 3 years, how much more
interest did he get from the simple interest deposit?

Answers

Step-by-step explanation:

Lets find out,shall we?

Simple interest=(PRT)/100

=$1000×12×3)/100

=$360

Now for compound interest

A=P(1+R/100)^t

A=$1000(1+12/100)^3

A=$1404.928

so interest for compound interest=$(1404.928-1000)=$404.928

Clearly,Robin got more interest by compound interest than simple interest which business people understand lol.

Difference in interest=$404.928-360=$44.928

Find the value of a in the polygon below. ​

Answers

Answer:.

m= 116 degrees

a=41 degrees

Step-by-step explanation:

Explaination: add 89+50+64 = 203

the line that m is on should equal 180. so subtract 64 from 180 and you get 116 degrees. then add 89+50+64+116=319

360-319= 41

the whole polygon should equal 360 degrees

20-34+ 8/2 =? PLS HELP ME I GIVE ALL MY POINTS.

Answers

Answer:

-10

Step-by-step explanation:

20-34=-14, 8/2 is just 4, so add 4 to -14 which = -10

folllowing the order of operations (parentheses, exponents, multiplication, division, addition, subtraction or PEMDAS) we know that we need to solve for 8/2 first.
8/2=4
then we know our new equation looks like 20-34+4=x. now we need to add.
34+4=38
now we have the new equation 20-38.
20-38=-18
your answer is -18.

The base of tyler's cabin is a 56 feet by 78 feet rectangle. What is the area of the base of tyler's cabin?

Strategy:

why did you choose this strategy:

Answers

Answer:  4368 square feet

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

Explanation:

Check out the diagram below

I drew a rectangle with dimensions 56 ft by 78 ft.

Then I broke up the 56 into 50+6, and I broke up the 78 into 70+8

The reason for this is because it's fairly easy to multiply the areas of each smaller rectangle at this point

In the upper left corner, we have an area of 50*70 = 3500. Note how this is basically 5*7 = 35, but we tack on the two zeros (from 50 and 70 combined)In the upper right corner, we have an area of 70*6 = 420In the lower left corner, we have an area of 50*8 = 400In the lower right corner, we have an area of 6*8 = 48

Add up all the areas found: 3500+420+400+48 = 4368

As a way to check, using your calculator shows that 56*78 = 4368

Write the slope of a line perpendicular to y=-6x+4. Explain why it is perpendicular

Answers

Answer:

1/6 is the slope since you have to flip it

Step-by-step explanation:

Answer:

The slope of a line perpendicular to the equation is 1/6 or x/6.

This is perpendicular because it is the reciprical of the other equation

Step-by-step explanation:

y=-6x+4.

the slope intercept form is y=mx+b

m is the slope

m=-6

for the equation to be perpendicular then the slope is the reciprical

Knowing this lets find a line perpendicular to this equation

Equation:

y=1/6x+2/3

or

y=x/6+2/3

Answers

Answer:

A

Step-by-step explanation:

Using the sine ratio on the right triangle on the right to find x

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{70}[/tex] ( multiply both sides by 70 )

70 × sin30° = x , thus

x = 35

-----------------------------------------------

Using the sine ratio on the right triangle on the left to find y

sin42° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex] = [tex]\frac{35}{y}[/tex] ( multiply both sides by y )

y × sin42° = 35 ( divide both sides by sin42° )

y = [tex]\frac{35}{sin42}[/tex] ≈ 52.3 ( to the nearest tenth ) → A

Answer:

y = 52.3.

Step-by-step explanation:

Consider the larger triangle on the right:

sin 30 = x / 70

x = 70 sin 30 = 70 * 0.5

= 35.

So, considering the small triangle:

Sin 42 = 35/y

y * sin 42 = 35

y = 35 / sin 42

y = 52.3.

what’s the perimeter?

Answers

Answer:

P = 16x+26y units

Step-by-step explanation:

Let the length is (x+8y) units

Width = (8x-x+5y) units

We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.

P = 2[(x+8y) + (8x-x+5y)]

= 2[(8x+8y+5y)]

= 2[8x+13y]

= 16x+26y

Hence, the required perimeter is 16x+26y.

An economist modeled the demand Q for a certain product as a linear function of the selling price p the demand was 20000 units when the selling price was $40 per unit and the demand was 15,000 units when the selling price was $60 per unit based on the model what is the time and in units when the selling price is $55 per unit

Answers

Answer: 16,250 units.

Step-by-step explanation:

This is a linear function which means that it takes the form of y = mx + c.

Y is the demand

X is the price

Find m.

= (Y₂ - Y₁) / (X₂ - X₁)

= (15,000 - 20,000) / (60 - 40)

= -250

Find c using substitution;

20,000 = -250 * 40 + c

20,000 = -10,000 + c

c = 20,000 + 10,000

c = 30,000

Linear function is;

y = -250x + 30,000

If selling price is $55;

y = -250 * 55 + 30,000

y = 16,250 units.

The demand is 17000 units when the selling price is $55 per unit

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let Q represent the demand and P represent the selling price.

20000 units for selling price of $40, hence (40, 20000). 16000 units for selling price of $60, hence (60, 16000).

Hence:

[tex]Q-Q_1=\frac{Q_2-Q_1}{P_2-P_1}(P-P_1)\\\\Q-20000=\frac{16000-20000}{60-40}(P-40)\\\\Q=-200P+28000[/tex]

For P = 55 unit:

W

Q = -200(55) + 28000 = 17000

The demand is 17000 units when the selling price is $55 per unit

A study concluded that among people with a certain​ virus, 99.2​% of tests conducted were​ (correctly) positive, while for people without the​ virus, 97.9​% of the tests were​ (correctly) negative. If 32​% of patients actually carry the​ virus, what's the probability that a patient testing negative is truly free of the​ virus?

Answers

Answer:

Following are the solution to the question:

Step-by-step explanation:

The probability of virus  P(V) =0.32  

No virus  P(NV) =0.66

Patient testing of negative P(TN) = virus, and negative testing+no virus and negative testing

[tex]=0.32(1-0.992)+0.66 \times 0.979 \\\\=0.00256+0.64614\\\\=0.6487[/tex]

This is why the likelihood of a patient being free of the virus is negative.

[tex]= \frac{P(NV) \times\ tested \ negative }{P(TN)}[/tex]  

[tex]= \frac{0.66 \times 0.979}{0.6487}\\\\= \frac{0.64614}{0.6487} \\\\=0.996053646[/tex]

Answers

Answer:

x = 5

Step-by-step explanation:

The sum of two complementary angle is 90 degrees. Given the following complementary angles;

<1 = 6x + 5

<2 = 8x + 15

<1 + <2 = 90 (complementary angles)

6x + 5 + 8x + 15 = 90

14x + 20 = 90

14x = 90-20

14x = 70

x = 70/14

x = 5

Hence the measure of x is 5

Example 3: The following data was collected by a taxi driver who was interested in how much fuel he used on different journeys. Length of journey 100 250 150 180 220 (miles) 300 Fuel Used (liters) 24 59 44 50 59 97 Estimate how much fuel would be needed for a 200-mile journey.​

Answers

Answer:

For a 200 mile journey, 55.5 liters of fuel

is needed

Step-by-step explanation:

Here, we want to estimate the fuel needed for a 200 mile journey

we can use this by having an average

By adding all and dividing by 6

Mathematically, that will be;

(24 + 59 + 44 + 50 + 59 + 97)/6

= 55.5

The reason for this is because if we added all the lengths and divide by 6, what we get is 200

Thus, if we added the liters of fuel used per each and divide by 6, we can have an estimate for a 200-mile journey

Given the vertices A (-4,3) B(-1,5) and C (-1,2).

If the vertices is reflected across the y = -1 line, the new location would be at:

A' (-4, -5). B'(-1, -7) and C'(-1, -4)
