Answer:

[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]

Step-by-step explanation:

There are a couple of  equivalent expressions to the function [tex]t+0.07t[/tex]. For example:

[tex]t+0.07t[/tex]

Factor:

[tex]t+0.07t=t(1+0.07)[/tex]

If you add the terms inside the parentheses:

[tex]t(1+0.07)=t(1.07)[/tex]

Basically you can add the like terms from the start and get the same result.

[tex]t+0.07t=1.07t[/tex]

Therefore:

[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]

Answer:

The circumference for circle a is [tex] \\ C = 131.9430[/tex]m.

The circumference for circle b is [tex] \\ C = 175.9240[/tex]m.

The relationship between the radius of a circle and the circumference (the distance around the circle) is constant and is the same for all circles and can be written as [tex] \\ \frac{C}{r} = 2\pi[/tex] or, in a less familiar form, [tex] \\ \frac{r}{C} = \frac{1}{2\pi}[/tex]. The number [tex] \\ \pi[/tex] is constant for all circles and has infinite digits, [tex] \\ \pi = 3.14159265358979....[/tex].

Step-by-step explanation:

The circumference of a circle is given by:

[tex] \\ C = 2*\pi*r[/tex] [1]

Where

[tex] \\ C[/tex] is the circle's circumference.

[tex] \\ r[/tex] is the radius of the circle.

And

[tex] \\ \pi = 3.141592....[/tex] is a constant value (explained below)

We can say that the distance around the circle is the circle's circumference.

The circumferences of the two circles given are:

Circle a, with radius equals to 21 meters ([tex] \\ r = 21m[/tex]).

Using [1], using four decimals for [tex] \\ \pi[/tex], we have:

[tex] \\ C = 2*\pi*r[/tex]

[tex] \\ C = 2*3.1415*21[/tex]m

[tex] \\ C = 131.9430[/tex]m

Then, the circumference for circle a is [tex] \\ C = 131.9430[/tex]m.

Circle b, with radius equals to 28 meters ([tex] \\ r = 28m[/tex]).

[tex] \\ C = 2*3.1415*28[/tex]m

[tex] \\ C = 175.9240[/tex]m

And, the circumference for circle b is [tex] \\ C = 175.9240[/tex]m.

We know that

[tex] \\ 2r = D[/tex]

That is, the diameter of the circle is twice its radius.

Then, if we take the distance around the circle and we divided it by [tex] \\ 2r[/tex]

[tex] \\ \frac{C}{2r} = \frac{C}{D} = \pi[/tex]

This ratio, that is, the relationship between the distance around the circle (circumference) and the diameter of a circle is [tex] \\ \pi[/tex] and is constant for all circles. This result is called the [tex] \\ \pi[/tex] number, which is, approximately, [tex] \\ \pi = 3.141592653589793238....[/tex] (it has infinite number of digits).

We can observe that the relationship between the radius of a circle and the circumference is also constant:

[tex] \\ \frac{C}{2r} = \frac{C}{D} = \pi[/tex]

[tex] \\ \frac{C}{2r} = \pi[/tex]

[tex] \\ \frac{C}{r} = 2\pi[/tex]

However, this relationship is [tex] \\ 2\pi[/tex].

We can rewrite it as  

[tex] \\ \frac{r}{C} = \frac{1}{2\pi}[/tex]

And it is also constant.

Answer:

Circle A is 42π

circle C is 56π

Answer:

The team lost 25 games and won 57.

Step-by-step explanation:

I am going to say what:

w is the number of games won.

As the problem states, l is the number of games lost.

The team won 7 more than twice as many games as it lost.

This means that [tex]w = 2l + 7[/tex]

A baseball team played 82 games.

This means that:

[tex]w + l = 82[/tex]

[tex]2l + 7 + l = 82[/tex]

[tex]3l = 75[/tex]

[tex]l = \frac{75}{3}[/tex]

[tex]l = 25[/tex]

And

[tex]w = 2l + 7 = 2*25 + 7 = 57[/tex]

The team lost 25 games and won 57.

Answer:

(-6,-2)

Step-by-step explanation:

Hello! Lets get started!

By looking at this problem, we see that both equations equal 2. This makes this problem much easier!

While there are a few methods you could solve this, I will use substitution. First, I need to find what x is in terms of y!

There are many different ways you could do this, here are two:

-x = 2-2y ==> x = -2+2y

-x + 2y = -3x + 8y ==> 2x = 6y ==> x = 3y

For this problem, I am going to use the second answer, x = 3y, as it is simpler!

We need to substitute 3y in for x in either equation; I am going to use the first equation, -x + 2y = 2.

-3y + 2y = 2

-y = 2

y = -2

Now, lets solve for x!

-x + 2(-2) = 2

-x - 4 = 2

-x = 6

x = -6

After plugging the answers into both equations, we see that they are in fact true!

Therefor, our final answer is (-6, -2)

Answer:

You have three card : 3, 4, and 5.

You first pick one card randomly, the probability of picking a 3 is:

P = 1/3

You then pick a second card without putting the first card back, the probability of picking a 5 is:

P = 1/2

=> The probability of picking a 3 and then picking a 5:

P = (1/3) x (1/2) = 1/6

Step-by-step explanation:

plug into the equation  known variables

Answer:

2257.50

Step-by-step explanation:

B=p(1+r)^t

p= principal amount= $7000 in the saving account

r= interest rate= 15%= .15

t- number of years = 2

B= 7000(1+.15)^2

B= 7000(1.15)^2

B= 7000(1.15)(1.15)

B= 9257.50

She has a total of 927.50 dollars in the account after two years. To find out how much of that is interest we take the Balance and subtract what she invested.

B-p= 9257.50-7000= 2257.50 earned in interest.

Given Information:

Principle amount = P = $9,129

Interest rate = r = 4% = 0.05

Period in years = t = 5

Required Information:

Balance in 5 years = ?

Answer:

Balance in 5 years = $11,651.17

Step-by-step explanation:

Using the formula given in the question,

[tex]B = P(1 + r )^{t}[/tex]

Where B is the final amount, P is the initial amount, r is the interest rate and t is the number of years

[tex]B = P(1 + r )^{t}\\\\B = 9,129(1 + 0.05)^{5}\\\\B = 11,651.17[/tex]

Therefore, Zack will have $11,651.17 in 5 years by investing $9,129 in a savings account at 5% annual interest.

Answer:

[tex]- 7 + \frac{2}{3}n = 13 : n = 30[/tex]

Step-by-step explanation:

[tex]-7+\frac{2}{3}n=13[/tex]

Add [tex]7[/tex] to both sides:

[tex]-7+\frac{2}{3}n+7=13+7[/tex]

Simplify:

[tex]\frac{2}{3}n=20[/tex]

Multiply both sides by [tex]3[/tex]:

[tex]3 * \frac{2}{3}n=20 * 3[/tex]

Simplify:

[tex]2n=60[/tex]

Divide both sides by [tex]2[/tex]:

[tex]\frac{2n}{2}=\frac{60}{2}[/tex]

Simplify:

[tex]n = 30[/tex]

Bank A has the highest possible overdraft fee.

An overdraft fee is charged when a payment or withdrawal from your bank account exceeds the available balance and your bank covers the transaction as part of an overdraft protection service. But in addition to covering the transaction, the bank or credit union then applies the fee.

If you don't bring your balance above zero, the bank may close your account and transfer an unpaid balance to a collection agency. Another form of overdraft protection that banks may offer is an automatic transfer from a linked account to cover a purchase if you don't have enough money in checking.

Answer:

x=6 y=-5

Step-by-step explanation:

6x+5y=11

X=1-y

6x=6(1-y)

6x=6-6y

6-6y+5y=11

6-y=11

y=-5

x=1-y

x=1-(-5)

x=6

so,

x=6

y=-5

Answer:

[tex]y = ( - 5) \\ x = 6[/tex]

Step-by-step explanation:

[tex]x = 1 - y \\ 6x + 5y = 11 \\ \\ \\ 6(1 - y) + 5y = 11 \\ 6 - 6y + 5y = 11 \\ - 6y + 5y = 11 - 6 \\ - y = 5 \\ y = - 5[/tex]

[tex]x = 1 - y \\ x = 1 - ( - 5) \\ x = 1 + 5 \\ x = 6[/tex]

Let's check whether the answer is correct.

[tex]6x + 5y = 11 \\ 6 \times 6 + 5 \times ( - 5) = 11 \\ 36 - 25 = 11 \\ 11 = 11[/tex]

Answer:

She does not have enough wire.

Step-by-step explanation:

The complete question included a design for her sculpture. It is a circle inscribe in a square and the length of the square is 9 inches. The picture above describe the design.

She has in possession a 5 ft of copper to construct a circle inscribe in a square.

The square is 9 inch length.

Perimeter of the square = 4L

where

L = length

Perimeter of the square = 4 × 9

Perimeter of the square = 36 inches

Circumference of a circle = 2πr

r = diameter/2 = 9/2 = 4.5 inches

Circumference of a circle = 2 × π × 4.5

Circumference of a circle = 2 × 4.5 × 3.14

Circumference of a circle = 9 × 3.14

Circumference of a circle = 28.26 inches.

The sculpture will consume 36 inches for the square and 28.26 inches for the circle. The total length for the sculpture will be 36 + 28.26 = 64.26 inches.

She has 5 ft copper for the sculpture . Let us covert the inches to ft to know if the copper wire is enough.

12 inches = 1 foot

64.26 inches = ?

cross multiply

wire required for the sculpture = 64.26/12

wire required for the sculpture = 5.355 ft

She does not have enough wire.

The slope is 3/2

Step-by-step explanation:

To find slope you do rise over run

Rise being how much you go up or go down

Run being how much you move sideways

Always measure Rise first, it is the numerator and then Run as the denominator.

Answer:

m= 3/2.

Step-by-step explanation:

To find the slope, use the two points shown in the graph which as (-1, 2) and (1, 5). Plug these into the slope formula [tex](m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}} )[/tex]

[tex]m= \frac{5-2 }{{1+1}}[/tex]
