All we need to do in solve for x in the given equation
x+4=7.8
x=3.8 (subtract 4 from both sides)

Therefore, the only value that will make the equation true is 3.8

Hope this helps

chris can be paid in one of two ways. plan a is a salary of $370 per month, plus a commission of 8% of sales. plan b is a salary

JulijaS [17]

Answer:

For a sale value greater than $7200 the plan a is profitable.

Step-by-step explanation:

Let us assume for a sale of $x, Chris will choose plan a.

Now, in plan a, a commission of 8% of sales and $370 per month, is the salary.

So, for a sale of $x the salary is $(370 + 0.08x) per month.

And, in plan b, a commission of 3% of sales and $730 per month, is the salary.

So, for a sale of $x the salary is $(730 + 0.03x) per month.

Now, for selecting plan a, the condition is

(370 + 0.08x) > (730 + 0.03x)

⇒ 0.05x > 360

⇒ x > 7200

Therefore, for a sale value greater than $7200 the plan a is profitable. (Answer)

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t

7nadin3 [17]

To solve this problem, we can use the tan function to find for the distances covered.

tan θ = o / a

Where,

θ = angle = 90° - angle of depression

o = side opposite to the angle = distance of boat from lighthouse

a = side adjacent to the angle = height of lighthouse = 200 ft

When the angle of depression is 16°18', the initial distance from the lighthouse is:

o = 200 tan (90° - 16°18')

o = 683.95 ft

When the angle of depression is 48°51', the final distance from the lighthouse is:

o = 200 tan (90° - 48°51')

o = 174.78 ft

Therefore the total distance the boat travelled is:

d = 683.95 ft - 174.78 ft

Use Pythagorean Theorem to solve for x.<br><br> HELP ME PLZZZZ!!!! ASAP

4vir4ik [10]

Answer: $2\sqrt{22}$

Step-by-step explanation:

Pythagorean theorem: $a^{2} +b^{2} = c^{2}$ , where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

$9^{2} +b^{2} = 13^{2}$

$81 +b^{2} = 169$

Since we don't know what $b^{2}$ is, we're going to isolate it by subtracting 81 on both sides

$b^{2} = 88$

We have to square root both sides in order to find out b (or x in the problem).

$\sqrt{b^{2}} = \sqrt{88}$

When you put this on a calculator it would result in $2\sqrt{22}$ which is the answer d in the problem.
