What is the range of possible sizes for side x?

jenyasd209 [6]

Answer:

$4$

Step-by-step explanation:

If a, b, c are three sides of the triangle, then

$a+b>c\\ \\a+c>b\\ \\b+c>a$

In your case, two sides have measures of 4 units and 8 units, then

$4+8>x\\ \\4+x>8\\ \\8+x>4$

Hence,

$12>x\\ \\x>4\\ \\x>-4$

Therefore,

$4$

Steve provides lawn care services in his neighborhood. For each lawn he charges a flat fee of 6 dollars for clean up and 10 doll

Taya2010 [7]

Answer:

$c(h) = 6 + 10h$

Step-by-step explanation:

We are given the following in the question:

Flat fee = 6 dollars

Charges per hour = 10 dollars per hour

Let Steve work for h hours.

Then, we can write the total charge in the following manner:

Total charge =

$=\text{Flat fee} + (\text{Number of hours}\times \text{Charges per hour})$

Putting values, we get,

$c(h) = 6 + 10h$

is the required equation for total charges if Steve worked for h hours.

Prove the following identity showing all steps:

kiruha [24]

Answer:

See solution below

Step-by-step explanation:

Given the expression

$\frac{cos(x+30)-sin(x+60)}{sin(x)cos(x)} \\$

Recall that

cos x = sin(90-x)

cos(x+30 ) = sin (90-(x+30)

= sin(90-x-30)

= sin(60-x)

Substitute

$\frac{sin(60-x)-sin(x+60)}{sin(x)cos(x)} \\= \frac{sin60cosx-cos60sinx)-sinxcos60-cosxsin60)}{sin(x)cos(x)} \\= \frac{-2cos60sinx)}{sin(x)cos(x)} \\= \frac{-2(1/2)sinx)}{sin(x)cos(x)} \\= \frac{-1}{cos(x)}\\= \frac{1}{cos(x)}\\ \\= -sec(x) Proved$

Bud's cheeseburger and fries contained 1310 milligrams and 350 milligrams of sodium, respectively. Together they contained 66.4%

Serhud [2]

Answer:

The recommended daily intake of sodium for a 2000 calorie diet is 2500 mg.

Step-by-step explanation:

In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.

$\text{total sodium} = 1310 + 350 = 1660 \text{ mg}$

We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:

$\frac{1660}{x} \frac{mg}{mg} = \frac{66.4\%}{100\%}$

$66.4*x = 1660*100\\x = \frac{166000}{66.4} = 2500 \text{ mg}$

The recommended daily intake of sodium for a 2000 calorie diet is 2500 mg.
