your answer in fully reduced form

Answer:

210

Step-by-step explanation:

Answer:

{x + y= 239

{15x + 5.50y = 2758.50

Step-by-step explanation:

x = adults    y = children and the total amount of people is 239.

$15 for adults and $5.50 for children and the total cost equals $2758.50.

The total number of tickets sold for the concert is 179.

Unitary method is a mathematical way of obtaining a single unit then deriving the required units by multiplying it with the single unit.

According to the given question The high school choir hosts a concert for the community.

Tickets are sold for this concert by members of the choir and at the door before concert.

Also given that 125 tickets are sold at the door and each member of the choir sell 3 tickets each and they were 18.

∴ The no. of tickets members of the choir sold is

= (18×3) = 54 tickets.

So, the total number of tickets sold for the concert is (125+54) = 179.

Answer:

f(5) = 22

Step-by-step explanation:

Plug in 5 as x into the function:

f(x) = 5x - 3

f(5) = 5(5) - 3

f(5) = 25 - 3

f(5) = 22

Answer:

20.6

Step-by-step explanation:

A virus takes approximately 20.6 days to triple its original population.

"[tex]f(x)=ab^x[/tex],

where a is the initial value

b is the growth rate

x is time. "

For given question,

Suppose the function for the population growth is,

[tex]A(t)=A_0\times b^t[/tex]                         .........(1)

For t = 13, the population growth of virus would be,

[tex]\Rightarrow A(13)=A_0\times b^{13}[/tex]                  ..........(2)

But we have been given that a virus takes 13 days to double its original population.

[tex]\Rightarrow A(13)=2\times A_0[/tex]                      .........(3)

From (2) and (3),

[tex]\Rightarrow A_0\times b^{13}=2\times A_0\\\\\Rightarrow b^{13}=2\\\\\Rightarrow b=1.0548[/tex]

We need to find the number of days  to triple its original population

[tex]\Rightarrow A(t)=3\times A_0[/tex]                   ...........(4)

From (1) and (4),

[tex]\Rightarrow A_0\times b^t=A_0 \times 3\\\\\Rightarrow (1.0548)^t=3\\\\\Rightarrow t=20.6[/tex]

Therefore, a virus takes approximately 20.6 days to triple its original population

Answer:

y=−1/7

for the picture is y=-57/7

Step-by-step explanation:

Switch:sides

-7y+7=8

subtract 7 from both sides

-7y=1

divide both sides by -7

y=−1/7

multiply both sides by (y+7)

8/y+7(y+7)=-7(y+7)

simplify 8=-7(y+7)

flip

-7(y+7)=8

divide both sides by -7

y+7=-8/7

subtract 7 from both sides

and simplify

y=-57/7

Answer:

[tex]t = 15.7[/tex]

Step-by-step explanation:

Given

[tex]Principal = 25000[/tex] --- P

[tex]Amount = 75000[/tex] --- A

[tex]Rate = 7\%[/tex] --- R

Required

Determine the time (t)

Using continuous growth formula:

We have

[tex]A = Pe^{rt}[/tex]

Convert rate to decimal

[tex]Rate = 7\%[/tex]

[tex]r = 0.07[/tex]

Substitute values for A, P and r

[tex]75000 = 25000 * e^{0.07t}[/tex]

Divide both sides by 25000

[tex]3 = e^{0.07t}[/tex]

Rewrite the exponential function as logarithmic, we have:

[tex]ln3 = 0.07t[/tex]

Reorder

[tex]0.07t = ln3[/tex]

Divide both sides by 0.07

[tex]t = \frac{ln3}{0.07}[/tex]

[tex]t = \frac{1.09861228867}{0.07}[/tex]

[tex]t = 15.69[/tex]

[tex]t = 15.7[/tex]

Hence, the time is approximately 15.7 years

Answer:hmmmmm

Step-by-step explanation:

Answer:

The answer is C.

Step-by-step explanation:

4(.032) + 3(2.458) = 7.502

7(.032) + 9(1.531) = 14.003

4(2.458) - 1.531 = 8.301

The solutions to the system of equation are x = 0.032, y = 2.458, z = 1.531 after using the inverse matrix method option (C) is correct.

It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.

We have a system of equations:

4x + 3y = 7.5

7x + 9z = 14

4y - z = 8.3

First we have to write above system of equation in the form of:

AX = B

[tex]\rm X = A^{-1}B[/tex]

Where A, X and B are the matrix such that:

[tex]\rm A = \left[\begin{array}{ccc}4&3&0\\7&0&9\\0&4&-1\end{array}\right][/tex]

[tex]\rm X = \left[\begin{array}{c}x\\y\\z\end{array}\right][/tex]

[tex]\rm B = \left[\begin{array}{c}7.5\\14\\8.3\end{array}\right][/tex]

[tex]\rm \left[\begin{array}{ccc}4&3&0\\7&0&9\\0&4&-1\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] \rm = \left[\begin{array}{c}7.5\\14\\8.3\end{array}\right][/tex]

Now find the determinant of matrix A

|A| = -123

[tex]\rm A^{-1}= \dfrac{Adj(A)}{Det(A)}[/tex]

After calculating, we will get:

x = 0.032, y = 2.458, z = 1.531

Thus, the solutions to the system of equation are x = 0.032, y = 2.458, z = 1.531 after using the inverse matrix method

Answer:

It would take 6 years for the value of the account to reach $5,920

Step-by-step explanation:

Principal Amount = $4900

Interest rate r = 3% = 0.03

Compounded monthly = n=12

Time t =?

Future Value = $5920

We can find time using formula: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Putting values and solving:

[tex]A=P(1+\frac{r}{n})^{nt}\\5920=4900(1+\frac{0.03}{12})^{12t} \\5920=4900(1+0.0025)^{12t}\\5920=4900(1.0025)^{12t}\\\frac{5920}{4900}= (1.0025)^{12t}\\1.21=(1.0025)^{12t}[/tex]

Applying exponent rule; [tex]a=b^c\\c\:ln(b)=ln(a)[/tex]

[tex]12t\:ln(1.0025)=ln(1.21)\\12t\:(0.00249)=0.19062\\t=\frac{0.19062}{12*0.00249}\\t=6.3\approx6[/tex]

There are 48 minnows in the aquarium and there are 18 clownfish in aquarium

Given that in an aquarium ratio of minnows and clown fish is 8:3 and the ratio of clownfish and goldfish are in ratio 6:11 and there are 33 gold fishes in the aquarium.

⇒[tex]\frac{6}{11} =\frac{x}{33}[/tex] ( Here x is the number of clownfish)

⇒x=6×3

⇒x=18

The value of x from the equation is  2√2

Linear equations are equations with one or two variables.

It is also important to note that the highest power of variable is 1

Given the equation;

yx² = 8y

Let's make 'x' the subject of the equation

Divide both sides by y, we have;

yx²/y = 8y/ y

x² = 8

Take the square root of both sides

(√x²) = √8

The square root takes the square, we have

x = √8

x = √4 × 2

x = 2√2

Thus, the value of x from the equation is  2√2
