The school that Molly goes to is selling tickets to a spring musical. On the first day of ticket sales the school sold 10 adult

Gre4nikov [31]

Answer:

Student ticket: $12, Adult ticket: $14

Equations: 260=10x+10y, 94=2x+5y

Step-by-step explanation:

Set adult tickets as y

Set student tickets as x

First day: Total made is 260 so set that equal to 10x + 10y

--> 260=10x+10y

Second day: Total made is 94 so set that equal to 2x + 5y

--> 94=2x+5y

I find it easier to have simplified terms so simplify (divide by 2) the first equation to get: 130=5x+5y

All you have to do now is solve for the two variables.

94=2x+5y - (130=5x+5y) --> x=12, y=14

What is the average rate of change for this function for the interval from x = 2<br> to x = 4?

Lelechka [254]

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ 2, 4 ]

From the table

f(b) = f(4) = 16

f(a) = f(2) = 4, hence

average rate of change = $\frac{16-4}{4-2}$ = $\frac{12}{2}$ = 6

Simplify!! Thank you :)

Nezavi [6.7K]

Combine like terms.

$2 {x}^{2} + 8 {x}^{2} = 10 {x}^{2}$

$x + 7x = 8x$

$4 + ( - 3) = 1$

So, the answer would be

$10 {x}^{2} + 8x + 1$

Find the volume of the given prism.<br><br>Ans:60cm^3

taurus [48]

Answer:

60 cm³

volume of triangular prism : area of base * Length

Given:

side of triangle : 4 cm

side of triangle : 3 cm

angle between 4 cm and 3 cm : 90°

Length : 10 cm

Find area of base:

$\rightarrow \sf \dfrac{1}{2} * side \ 1 \ * side \ 2 \ * \ sin (\theta)$

$\rightarrow \sf \dfrac{1}{2} *\ 4 \ * \ 3 \ * \ sin (90)$

$\rightarrow \sf 6 \ cm^2$

Volume :

A * L

6 * 10

60 cm³

When 70% of a number is added to the number, the result is 221. What is the number?

Sholpan [36]

Answer: 130

Step-by-step explanation:

so 0.7x + x = 221

so 1.7x = 221

divide both sides by 1.7 to get

x = 130
