How do i solve this?

Ierofanga [76]

Step 1: Simplify both sides of the equation.

−36=p−30

Step 2: Flip the equation.

p−30=−36

Step 3: Add 30 to both sides.

p−30+30=−36+30

p=−6

Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instr

stepladder [879]

Answer:

Laurie's maximum depth can be represented using the expressions :

(20 × 3) = 60

(3 × 4 × 5) = 60

Step-by-step explanation:

Each depth level at which ears are checked = 5 feets

Each Depth level at which instruments are checked = 20 feets

For Laurie to check her instrument ;

Number of times ears are checked = 20/5 = 4 times

This means that for Laurie to have checked her instrument 3 times :

(4 × 3 × 5) = 60 feets

Therefore, Laurie's maximum depth can be expressed as (4 × 3 × 5) = 60 feets

A cable is installed around two edges of the rectangular field that is 860 feet long and 340 feet wide, as shown below. Suppose

raketka [301]

Answer:

a. 2,520,000.00

b. $1,942,017.51

c. $577,982.49

Step-by-step explanation:

Distances in a Rectangle

Running the cable along the edges of the field would need a total length of 860 ft + 340 ft = 1,200 ft of cable. The unit cost of the cable is $2,100 per foot, thus the cost of the total lenght of cable was 2,100*1,200= $2,520,000.

b. If the cable ran along the diagonal, the distance must be computed by

$D=\sqrt{x^2+y^2}$

where x = 860 ft and y = 340 ft, thus

$D=\sqrt{860^2+340^2}=924.77$

D = 924.77 ft. The cost of the cable would be 2,100*924.77= $1,942,017.51

c. The savings if the cable were installed along the diagonal of the field instead of around the edges of the field would be

$2,520,000 - $1,942,017.51 = $577,982.49
