Answer:

5.5; 11.00; 16.50

$E = 5.5h$

Step-by-step explanation:

Given

The attached table

Solving (a): Complete the table

First, calculate the slope (m)

$m = \frac{E_2 - E_1}{h_2 - h_1}$

So:

$m = \frac{27.5- 22.00}{5-4}$

$m = \frac{5.50}{1}$

$m = 5.50$

So, the equation of the table is:

$E = m(h - h_1) + E_1$

$E = 5.5(h - 4) + 22$

$E = 5.5h - 22 + 22$

$E = 5.5h$

When h =1,2,3

$E = 5.5 * 1 = 5.5$

$E = 5.5 * 2 = 11.00$

$E = 5.5 * 3 = 16,50$

The school that Scott goes to is selling tickets to the annual dance

zalisa [80]

Senior tickets (x)
Child tickets (y)

First day: 3x + 5y = 70

second day: 12x + 12y = 216

Solve the system of equations (use elimination)

Multiply first equation by -4 -4(3x + 5y = 70), which makes it

-12x - 20y = -280
(+)12x + 12y = 216 add to second equation

-8y = -64

divide by -8. y = 8

Plugin the y value to either equation ( I will choose first equation)

3x + 5(8) =70

3x+ 40 = 70

3x = 30

x = 10

Senior tickets are $10, child tickets are $8

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

mars1129 [50]

The pool has area $160\,\mathrm{ft}^2$ .

Let $x$ be the width of the sidewalk. Then the combined area of the pool and sidewalk is $(10+x)(16+x)=160+26x+x^2$ , so that the area of the sidewalk alone is $26x+x^2$ .
