If a car travels 10 ft due north and then 15 feet due west, how far is the car from it starting point? This is for homework and
krok68 [10]
Answer:

Explanation:

The car travel 10ft north then 15ft due west. In order to find the distance from starting point. We need to find the hypotenuse where the distance to north and west are the adjacent side.

We can use Pythagorean’s theorem according to that:

Let c be the distance from starting point.
And a and b be the distance travel to north and west.

a^2 + b^2 = c^2
10^2 + 15^2 = c^2
100 + 225 = c^2
325 = c^2
Sqrt(325) = c
5sqrt(13) = c

Therefore, the distance from starting point is 5sqrt(13) ft

You can work at most 20 hours next week. You need to earn at least $90 to cover your weekly expenses. Your dog walking job pays
Vadim26 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x ----> the dog walking hours

y ----> the car washing hours

we know that

The system of linear inequalities is equal to

x+y\leq20 -----> inequality A

9x+10y\geq 90 -----> inequality B

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

Two possible combinations of hours are

(10,10) and (0,9)

<em>Verify</em>

For (10,10)

Substitute the value of x and the value of y in both inequalities

<em>Inequality A</em>

10+10\leq20

20\leq20  -----> is true

<em>Inequality B</em>

9(10)+10(10)\geq 90

190\geq 90 ----> is true

therefore

(10,10) is a possible solution

For (0.9)

Substitute the value of x and the value of y in both inequalities

<em>Inequality A</em>

0+9\leq20

9\leq20  -----> is true

<em>Inequality B</em>

9(0)+10(9)\geq 90

90\geq 90 ----> is true

therefore

(0,9) is a possible solution
