find the interest rate you are borrowing $2,500 for 2 years and you ear $450 in interest

Answer:

Below

Step-by-step explanation:

Perimeter = 446

446 = (13x-1) + (13x-1) + (9x+4) + (9x+4) ft      <====four sides added together

446 = 44x +6

440 = 44x

x = 10                 then width = 9(10)+4 = 94 ft     Length = (13(10)-1) = 129 ft

The properties shown in each statement are given as follows:

1. 4m x 0 x 3m = 0 -> neutral element of the multiplication.

2. 5 + (a + 17) = (5 + a) + 17 -> associative property of addition.

The first expression is given as follows:

4m x 0 x 3m = 0.

A multiplication by zero will always result in a value of zero, hence the property is of the neutral element of the multiplication.

The second expression is given as follows:

5 + (a + 17) = (5 + a) + 17.

The change is in the order in which the terms are added, which does not change the value of the sum, hence the property is the associative property of addition.

Answer:

no

Step-by-step explanation:

simple interest formula:

final amount = initial balance * (1 + interest rate * time)

rate = 7.5% = 0.075

initial balance = 320

time = 3

is the final amount of 320 * (1 + 0.075 * 3) greater than or equal to 400?

320 * (1 + 0.075 * 3) = 392 so no

Answer: There were 304 children and 89 adults at the public pool on that hot summer day.

Step-by-step explanation:    

Let's say the total number of people at the pool that day is x + y = 393

   The total cost of admission for all the people is $678.50

   The cost for each child's admission is $1.50 and the cost for each adult's admission is $2.50

We can use this information to set up two equations:

   x + y = 393 (Total number of people)

   1.5x + 2.5y = 678.5 (Total cost of admission)

Now we can use the first equation to solve for one of the variables. For example, we can solve for y:

y = 393 - x

We can substitute this value of y into the second equation:

1.5x + 2.5(393 - x) = 678.5

We can then solve this equation for x:

1.5x + 982.5 - 2.5x = 678.5

-x = -304

x = 304

This means that there were 304 children at the pool that day. We can use the first equation to find the number of adults:

x + y = 393

304 + y = 393

y = 393 - 304

y = 89

Therefore, there were 304 children and 89 adults at the public pool on that hot summer day.

Answer:

a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192

Step-by-step explanation:

A geometric sequence is a sequence of numbers such that the ratio of any two consecutive terms is always the same. In this case, the given sequence is -3, -12, -48, -192, -768.

To find the explicit formula for this geometric sequence, we can use the following formula:

an = a1 * r^(n-1)

where:

a1 is the first term in the sequence (-3)

an is the nth term in the sequence

r is the common ratio (the ratio between any two consecutive terms)

To find the common ratio, we can divide -12 by -3, -48 by -12, -192 by -48, and -768 by -192, and in all cases we get r = 4

Therefore, the explicit formula for this geometric sequence is:

an = -3 * 4^(n-1)

This formula can generate any term of the sequence given the value of n.

So, for example, the fourth term of the sequence, -192, can be obtained by inputting n = 4 in the explicit formula:

a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192

There are 231+d pies baked in two years.

expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An equation is made up of two expressions connected by an equal sign.

Since we have given that

Number of pies baked for bake sale last year = 231

Number of pies baked for bake sale this year = d

So, total number of pies baked in two years is given by

231 +d

Hence, there are 231+d pies baked in two years.

Answer:

7.5 hours

Step-by-step explanation:

let t represent time, l represent length and n represent number of painters.

given t varies directly with l and inversely with n then the equation is

t = [tex]\frac{kl}{n}[/tex] ← k is the constant of variation

to find k use the condition t = 5 when l = 200 and n = 3 , then

5 = [tex]\frac{200k}{3}[/tex] ( multiply both sides by 3 )

15 = 200k ( divide both sides by 200 )

0.075 = k

t = [tex]\frac{0.075l}{n}[/tex] ← equation of variation

when l = 500 and n = 5 , then

t = [tex]\frac{0.075(500)}{5}[/tex] = [tex]\frac{37.5}{5}[/tex] = 7.5 hours

Using the concept of similar triangles, the height of the tree is; Option D: 38 ft 6 inches.

Similar triangles are defined as triangles that have the same shape, but then their sizes may vary. This means that equilateral triangles and squares are good examples of similar objects. Thus, if two triangles are similar, then it means that their corresponding angles are congruent and corresponding sides are in equal proportion.

Thus, applying the principle of similar triangles above to the given image, if the height of the tree is h, then we have;

5/3.25 = h/25

h = (25 * 5)/3.25

h = 38.462 ft = 38 ft + 0.462 ft

Now, conversion of ft to inches gives 0.462 ft approximately 6 inches Thus, our final answer is 38 ft 6 inches.

Answer: A transformation of a function such as y = f(x) is a way to change the appearance of its graph by applying certain rules to it. In this case, the graph of function g is a translation right 5 units and up 1 unit of the graph of f.

To find the equation of the transformed function g, we can take the equation of the parent function, which is y = f(x) = x^2 and apply the translation rules (right 5 units and up 1 unit) to it.

The translation right 5 units means that the x-coordinate of each point on the graph of f is increased by 5 units. So this can be written as x = x+5

The translation up 1 unit means that the y-coordinate of each point on the graph of f is increased by 1 units. So this can be written as y = y+1

Substituting x = x+5 and y = y+1 in the equation of the parent function y = x^2 gives the equation of g in the form:

y = (x+5)^2 + 1

So the equation of g is y = (x+5)^2 +1

The circle with a 7 feet radius cut into 6 equal sectors, indicates, using 22/7 approximation for pi, that the area of 2 of the pieces is 51 and one third square feet. The correct option is option C.

C. 51 and one third square feet

A sector of a circle is a pie shaped part of a circle that is bounded by an arc and two radii of the circle.

The specified radius of the circle, r = 7 feet

The number of pieces to which the circle is cut into = 6 equal pieces (sectors)

The area of 2 of the pieces, using 22/7 as an approximation for π are found as follows;

Area of a circle, A = π × The square of the radius

Therefore; A = π × r²

A = (22/7) × 7² = 154

The area of the circle is about A = 154 square feet

The area of one of the pieces into which the circle is cut is therefore;

Area of a piece = A/6

Area of one piece = (154 square feet)/6 = 25 and two thirds square feet

The area of 2 of the pieces = 2 × (A/6) = A/3

Therefore, the area of two of the pieces = (154 square feet)/3 = 51 1/3

The area of 2 of the pieces = [tex]51\frac{1}{3}[/tex] square feet

Answer:

The probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%

Step-by-step explanation:

The probability of rolling a seven on any given roll of two dice is 1/6, since there are six ways to roll a seven (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) out of the 36 possible outcomes (1-6 on the first die and 1-6 on the second die).

To find the probability of rolling a seven on or before the 5th roll, we can use the cumulative probability formula which is the probability of getting a specific event on the first roll plus the probability of getting the event on the second roll plus the probability of getting the event on the third roll and so on.

So the probability of rolling a seven on or before the 5th roll is:

P(rolling a seven on the 1st roll) + P(rolling a seven on the 2nd roll) + P(rolling a seven on the 3rd roll) + P(rolling a seven on the 4th roll) + P(rolling a seven on the 5th roll)

= (1/6) + (1/6) + (1/6) + (1/6) + (1/6)

= 5/6

So the probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%

It's worth noting that this probability is independent of the previous outcomes of the rolls, so the probability of rolling a seven on or before the 5th roll stays the same even if you already rolled a seven in previous rolls.
