Answer:

10 years

Hence, it will take 10 years for the sum of money to double itself with the rate of 10% per annum simple interest. Note: While solving questions related to principal interest, it is important to keep in mind that simple interest calculated from the formula, Simple Interest (I) = P × R × t 100, doesn’t represent the total amount of money.

Answer:

Slope: 6

Y-intercept: 0

Proportional

Step-by-step explanation:

The equation for this table is y = 6x + 0 or just y = 6x.

y         =            6x           +                0

y-value          slope (x-value)           y-intercept

Proportional because it crosses (0,0) on the graph.

Answer:

x=50

Step-by-step explanation:

1. equal the equations to each other: 2(x+10)=3x-30

2. distribute the 2 to x+10: 2x+20=3x-30

3. subtract 2x from both sides, and add 30 to both sides: x=50

Answer:

189 degrees

Step-by-step explanation:

To answer this we need to know the theorem that where the sum of two remote angles equal the exterior angle. therefore we can make the statement  15x + 34 = 29 + 12x + 26

now we do algebra

3x = 31

x= 31/3

we now plug this into the exterior angle

we get 15 * 31/3 + 34

and we get 189 degrees.

Answer:

41°

Step-by-step explanation:

Little confused about what exterior angle but for the unlabelled angle in the triangle:

As all angles on a straight line should add up to 180, let the unknown angle be y:

180 = 15x + 34 + y

However, we also know that all angles in a triangle must add up to 180:

y + 29 + 12x + 26

Meaning:

15x + 34 + y = y + 29 + 12x + 26

Step 1 - Subtract y from both sides and add like terms:

15x + 34 + y - y = 12x + 29 + 26 + y - y

15x + 34 = 12x + 55

Step 2 - Subtract 34 from both sides of the equation:

15x + 34 - 34 = 12x + 55 - 34

15x = 12x + 21

Step 3 - Subtract 12x from both sides:

15x - 12x = 12x - 12x + 21

3x = 21

Step 4 - Divide both sides by 3:

3x ÷ 3 = 21 ÷ 3

x = 7

Step 5 - Plug into the first equation:

15x + 34 + y = 180

15(7) + 34 + y = 180

105 + 34 + y = 180

139 + y = 180

y = 180 - 139

y = 41

Hello there!

These numbers are called reciprocals.

A reciprocal is a number flopped over.

Answer:

"The ratio of the number of cats to dogs is 3:5. How many dogs would there be if there were 12 cats?"

Reworded, this says that "for every 3 cats there are 5 dogs."  Or else you could say, "for every 5 dogs there are 3 cats."

You are given the number of cats=12.  For every 3 cats there are 5 dogs."  That means 50 dogs.

 (3 cats) / (5 dogs) = (12 cats) / (x dogs)

  3 / 5 = 12 / x

   3x = 5*12

    3x = 60

      x = 20 dogs

Or you could write:

  (5 dogs) / (3 cats) = (x dogs) / (12 cats)

    x = 20 dogs.

Step-by-step explanation:

An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0.To start the room contained 20 dogs.

Mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another. Two quantities are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent."

According to a revised version, "there are 5 dogs for every 3 cats." Alternatively, you may say, "There are 3 cats for every 5 dogs."

You are informed that there are 12 cats. There are 5 dogs for every 3 cats. That's fifty dogs.

3 cats divided by 5 dogs equals 12 cats (x dogs)

3 / 5 = 12 / x

3x = 5*12

3x = 60

x = 20 dogs

Answer:

$11091.23

Step-by-step explanation:

Reword the situation:

She purchased a car for 18791 dollars 39 months ago.

As the 39 months passed she has been paying 197.43 a month.

How much does she still owe for her car?

First find out how much she's paid so far.

For 39 months she has been paying 197.43 a month

So, so far she's payed a total of 197.43 * 39 = 7699.77 dollars

Now subtract amount she's paid so far from total price of car.

18791 - 7699.77 = 11091.23

She still owes 11091.23

Answer:

Do the same thing for the other exercises and you should find the results. They are all complimentary angles, that means if you sum the two equations representing the angles of each exercise they will be equal to 180º always

Step-by-step explanation:

3. notice 2x is complimentary of 2x + 80 because 2x is opposed to that blank space that compliments it.... I'm bad at explaining, I'll just show.

2x + 2x + 80 = 180

4x + 80 = 180

4x = 180 - 80

4x = 100

x = 25º

so then:

2x = 2*25

2x = 50º

and:

2x + 80 = 50 + 80

2x + 80 = 130º
