Answer:

Yes

Step-by-step explanation:

Find a common denominator, so you could do 100. Multiply 40/25 by 4 to get 160/100. Then to get the other denomination to 100 multiply by 5, so 32/20 = 160/100

avanturin [10]

Answer:

B) 47.1°

Step-by-step explanation:

The tangent relation is useful here.

Tan = Opposite/Adjacent

The original height of the tree is the side of the triangle that is opposite the angle of elevation:

Opposite = Adjacent × Tan

original height = (25 ft)×tan(34°) ≈ 16.863 ft

After growing an additional 10 ft, the tree has a height of ...

16.863 ft + 10 ft = 26.863 ft

Then the angle of elevation is found from ...

tan(angle) = (26.863 ft)/(25 ft) ≈ 1.07451

angle of elevation = arctan(1.07451) ≈ 47.057°

The angle of elevation to the top of the tree is about 47.1°.

2/3x=−1/3x−4<br><br> (they are not being divided)

Mashutka [201]

2/3(x)-(-1/3(x)-4)=?
?=0

1÷3 = 0.3

2/3(x) - 0 -1/3(x) = ?
? = 0

2 ÷ 3 =.67

4(3)/ 3

your "x" becomes a negative

So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other

Your like term of this problem▶ -x + 12

2(x) - (-x) - 12 / 3

3(x) + 12

x + 4 = 0
-4 -4
---- ----
4x - 4

4x - 4 = 0

We have one solution to this equation

So, therefore your answer for this question is:
x = -4
