Answer:

Step-by-step explanation:

Solve for each choice until you get the answer 1/5.

2 - 4/5

10/5 - 4/5 = 6/5; this is not 1/5

8 - 8/5

40/5 - 8/5 = 32/5; this is not 1/5

3 - 16/5

15/5 - 16/5 = -1/5

5 - 26/5

25/5 - 26/5 = -1/5

7 - 36/5

35/5 - 36/5 = -1/5; although this is negative, it still has the same proportionality of 1/5

Please help i dont get this at all

Tom [10]

Answer:

$\frac{20y^{2} a^{2} }{41bx^{3} }$

Step-by-step explanation:

1) Flip the second fraction and change the operation to multiplication:

$\frac{5x^{2}y^{3} }{2a^{5}b^{4} } * \frac{8a^{7}b^{3} }{41x^{5}y }$

2) Cross cancel factors:

$\frac{5y^{2} }{2b } * \frac{8a^{2} }{41x^{3} }$

3) Multiply:

$\frac{40y^{2} a^{2} }{82bx^{3} }$

4) Simplify:

$\frac{20y^{2} a^{2} }{41bx^{3} }$

Answer:

8 interior angles

Step-by-step explanation:

There is a simple trick to finding the number of interior angles
For instance, a triangle has 3 sides, and how many angles are in a triangle? 3
A square has 4 sides and 4 interior angles
A pentagon has 5 sides and 5 interior angles
So an octagon, the shape we have here, has 8 sides so 8 interior angles

In △ E F G , △EFG, G E ‾ ≅ F G ‾ GE ≅ FG and m ∠ F = 5 5 ∘ . m∠F=55 ∘ . Find m ∠ E . m∠E.

Bingel [31]

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

$\overline{GE}$ ≈ $\overline{FG}$

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.
