First, you would need to create an equation for this problem. Let x represent the number of sales made.
$100 + $3x = $160
Next, you would need to isolate the x.
Subtract $100 from both sides.
$3x = $60
Now, all you would need to do is divide both sides by $3.
x = 20
You would need to make at least 20 sales.
I hope this helps!
Answer:
15.45
Step-by-step explanation:
103x0.15=15.45
This is a problem of
fact families, but <em>what is fact families?</em> Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by w<span>riting the <em>subtraction fact two ways</em>. So we have:
</span><span>
First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:
</span>Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
So I want to take away 3 triangles, then by taking away 3<em> what is left? </em>Well the answer is 7:
Δ Δ Δ Δ Δ
Δ Δ
That is, if we subtract 3 from 10 then the result is:
Second way. In this subtraction we take the same 10 triangles:
Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
Now I want to take away 7 triangles, then by taking away 7 what is left is 3:
Δ Δ Δ
That is, if we subtract 7 from 10 then the result is:

Answer:
17.5 meters
Step-by-step explanation
I included an illustration of what they are asking for.
- Notice, since the light of the sun is coming from the same place, the shadow angles relative to the ground, X and Z, will be the same. So the triangles formed are similar
- Use SOH CAH TOA to find the angle Z
- This just means when you have an angle in a right triangle, in order to know whether to use Cosine, Sine or Tangent, look at what sides you have
- We have the sides opposite (O) and adjacent (A) to angle Z, so we tangent (T)
-
- Now since angle Z equals X, they have the same tangent value
- So we can use that to find the building height, which it the opposite (O)
- Don't forget to use the new adjacent 14m
-
