You save $3,260.00 in a savings account earning a 3.55% APR compounded monthly. How much is the total interest earned by the end of the third month? a) $23.56 b) $21.02 c) $28.59 d) $27.01

Answer: W= 0.5

Step-by-step explanation:

You add 3w to both sides to get -5= 10w and then you divide everything by 10 to get w= 0.5

-5 - 3w = 7w

-5 - 3w+3w = 7w+3w <<--- add 3w to both sides

-5 + 0w = 10w

-5+0 = 10w

-5 = 10w

10w = -5

10w/10 = -5/10 <<--- divide both sides by 10 to isolate w

w = -5/10

w = -1/2 <<--- reduce; this is the answer in fraction form

w = -0.5 <<---  this is the answer in decimal form

I used Google and got 90%...if you simplify it you will get 9/10 which is a 90%

If 18 out of 20 is given. Then the percentage will be 90%.

Answer:

n-20

--------

3a

Step-by-step explanation:

(3ax - n)/5 = -4

The first step is to multiply each side by 5 to get rid of the fraction

(3ax - n)/5  * 5= -4* 5

3ax - n = -20

Then we need to add n to each side.

3ax -n+n = -20+n

3ax = n-20

Divide each side by 3a to isolate x

3ax/3a = (n-20)/3a

x = (n-20)/(3a)

The probability that the red die shows a number larger than three or the green die shows a number less than three is 0.83 or 83%.

The question relates to the topic of probability in mathematics, which is the measure of the likelihood that an event will occur. In this case, we are looking at the probability of combined events with two standard six-sided dice, one red, and one green.

Firstly, the probability that the red die rolls a number larger than three is 3/6 or 0.5 since, out of 6 possible outcomes (1, 2, 3, 4, 5, 6), 3 (4, 5, 6) are favorable outcomes.

Secondly, the probability that the green die shows a number less than 3 is also 2/6 or approximately 0.33, as there are two favorable outcomes (1 and 2).

To find the probability of the red die showing a number larger than three OR the green die showing a number less than three, we add the two individual probabilities because these are independent events. Hence Probability = 0.5+0.33 = 0.83 or 83%

The probability of the red die showing a number larger than three or the green die showing a number less than three is 1/9.

To calculate the probability of the red die showing a number larger than three or the green die showing a number less than three, we need to determine the number of favorable outcomes and the total number of possible outcomes.

The favorable outcomes are when the red die shows a number larger than three (i.e., 4, 5, or 6) or when the green die shows a number less than three (i.e., 1 or 2).

Since each die has 6 sides, the total number of possible outcomes for each die is 6. Therefore, the total number of possible outcomes for both dice is 6 * 6 = 36.

The number of favorable outcomes is 3 (for the red die) + 2 (for the green die) - 1 (for the outcome where both dice show a number larger than three and a number less than three) = 4.

Therefore, the probability is 4/36 = 1/9.

Answer:

2 feet per year

Step-by-step explanation:

First, we need to find the amount it grew:

13 - 3 = 10

So between 2005 and 2010 it grew 10 feet.

Now to find the yearly growth we need to divide the distance by time:

10 ÷ 5 = 2

So it grew 2 feet per year.

Let the number of toys Teddy has on Monday = x

On Monday Harry has = 75% of x or 0.75x

As given, On Tuesday, after Harry acquired 32 more toys and Teddy acquired 15% more than he had on Monday, Harry had as many toys as Teddy did.

Toys Teddy has = [tex]x+\frac{15x}{100}[/tex]

=[tex]\frac{100x+15x}{100} =\frac{115x}{100}[/tex] = 1.15x   .... (i)

Toys Harry has = 0.75x+32   ...... (ii)

As both have equal toys now, so equation (i) equals equation (ii)

[tex]1.15x=0.75x+32[/tex]

[tex]1.15x-0.75x=32[/tex]

[tex]0.4x=32[/tex]

x=80

Hence, Teddy had 80 toys on Monday.

And Harry had 75% of 80 toys = 60 toys on Monday.

Answer:

Domain: [tex]\mathbb{R}[/tex]

Inverse: [tex]f^{-1}(x) = -x + 5[/tex]

Step-by-step explanation:

Since this is a linear function, the domain and range is simply the set of real numbers.

The inverse is obtain by switching the places of x and y, then solving for y.

Here,

y = -x + 5

So switching x and y,

x = -y + 5

Solving for y again,

y = -x + 5

Thus,

[tex]f^{-1}(x) = -x + 5[/tex]

Answer:

The domain of linear function is always the set of all real numbers

Range is also the set of all real numbers

[tex]f^{-1}=-x+5[/tex]

Step-by-step explanation:

[tex]f(x) = -x + 5[/tex]

Domain is the set of x value and range is the set of y value. There is no restriction for x  and y in a linear function.

The domain of linear function is always the set of all real numbers

Range is also the set of all real numbers

Now find the inverse

[tex]f(x) = -x + 5[/tex]

Replace f(x) with y

[tex]y = -x + 5[/tex]

Replace x with y and y with x

[tex]x = -y + 5[/tex]

Subtract 5 from both sides

[tex]x-5=-y[/tex]

Divide both sides by -1

[tex]y=-x+5[/tex]

Replace y by f^-1

[tex]f^{-1}=-x+5[/tex]

the correct answer to this question would be: y=8

−(−y+18)+11  =1

y−18+11        =1

y−7              =1

y                  =8

Andre states that the applied interest is simple interest, this statement is true.

Step-by-step explanation:

From the given table it is noticed that the value of y increased by 17.50 as the value of x increased by 1.

The rate of change is calculated as

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

For first two years the rate of change is

[tex]m=\frac{535.00-517.50}{2-1}=17.50[/tex]

The rate of change for next two years is

[tex]m=\frac{552.50-535.00}{2-1}=17.50[/tex]

Similarly, the rate of change for all years in 17.50.

Since the rate of change is same for all years, therefore the future value is increased by a constant rate, therefore the applied interest is simple interest.

So, the statement "the applied interest is simple interest" is true.

Answer:

27 children.

Step-by-step explanation:

For every 9 children there are 4 adults .

x + y = 39  where x = number of children and y = number of adults.

and x/y = 9/4

so  4x = 9y

then x =  9y/4 , so substituting for x in the first equation:-

y + 9y/4 = 39        Multiplying through by 4:-

4y + 9y =  156

y = 156/13 = 12  so there are 12 adults

and 39 - 12 = 27 children

The problem is solved by using the ratio of children to adults and setting up a proportion. After cross-multiplying and solving the equation, it is determined that there are 27 children at the movie.

This is a problem of ratio and proportion. In this case, the ratio of children to adults at the movie is 9 to 4. This means that for every 13 people at the movie (9 children plus 4 adults), 9 are children. We can set up a proportion to determine how many out of the total 39 people at the movie are children.

The proportion is:
9 children / 13 total people = x children / 39 total people

We can solve this problem by cross multiplying: 9 * 39 = 13 * x, which gives us: 351 = 13x. Dividing both sides of the equation by 13, we get: x = 27.

Therefore, 27 children are at the movie.

Answer: 10/9

Step-by-step explanation:

On the width:

6 yards = 18 feet

24 inches = another 2 feet

Total width = 20 feet

On the length:

6 yards = 18 feet

Ratio of width to length = (20 feet) / (18 feet) = 10/9

The actual width of the garden is 72 inches, which is equivalent to 2 yards

To determine the actual width of the flower garden, we need to use the given scale of 1:12. This means that 1 inch on the plan represents 12 inches in reality. Given that the flower garden is 6 inches wide on the plan, we set up a proportion to find the actual width.

The proportion is:

1 inch on plan : 12 inches in reality = 6 inches on plan : x inches in reality

So we calculate:
(1 inch / 12 inches) = (6 inches / x inches)

Now we solve for x:
1/12 = 6/x
x = 6 * 12
x = 72 inches

Therefore, the actual width of the garden is 72 inches, which can be converted into yards by knowing that 1 yard equals 36 inches. Thus, 72 inches is equivalent to 2 yards (since 72 / 36 = 2).
