Which of the following expressions is equal to 5^6/5^2
A) 5.5.5
B) 1/5.5.5.5
C) 5.5.5.5
D) 3
Answer:
[tex]\dfrac{5^6}{5^2}[/tex] = [tex]5{\cdot}5{\cdot}5{\cdot}5[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{5^6}{5^2}[/tex]
We need to find this expression is equal to what.
[tex]\dfrac{5^6}{5^2}=\dfrac{5^4\times 5^2}{5^2}\\\\=5^4\\\\=5\times 5\times 5\times 5\\\\\text{or}\\\\=5{\cdot}5{\cdot}5{\cdot}5[/tex]
Hence, [tex]\dfrac{5^6}{5^2}[/tex] is equal to [tex]5{\cdot}5{\cdot}5{\cdot}5[/tex]. Hence, the correct option is (c).

Step-by-step explanation:
Given ΔPQR and ΔSTU, what is m∠Q?
Given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.
Similar TrianglesThe ratios of the corresponding sides of similar triangles are always equal to each other, that is, the corresponding sides are proportional.Also, corresponding angles of two similar triangles are congruent.Thus:
ΔPQR and ΔSTU are similar because:
PQ/ST = PR/SU = QR/TU = 3.5
Therefore,
m∠Q = 180 - 70 - 46
m∠Q = 64°
Thus, given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.

The shadow of a 60 foot pole is a 100 feet long. What is the angle of evaluation from the end of the shadow to the top of the pole?
Answer:
θ = 36.86°
Step-by-step explanation:
Given that,
The shadow of a 60 foot pole is a 100 feet long.
We need to find the angle of elevation from the end of the shadow to the top of the pole.
Height, h = 60 foot
Hypotenuse, H = 100 feet
Using trigonometry to find it.
[tex]\sin\theta=\dfrac{\text{Height}}{\text{Hypotenuse}}\\\\\sin\theta=\dfrac{60}{100}\\\\\theta=\sin^{-1}(\dfrac{60}{100})\\\\\theta=36.86^{\circ}[/tex]
So, the angle of elevation is 36.86 degrees.

Which statements below are ALWAYS TRUE about Rectangles? Choose ALL THAT APPLY.
- Diagonals are perpendicular
- Diagonals bisect each other in diagonals are equal in length
- Diagonals bisect each other, but they are NOT equal in length
- Opposite sides are congruent
- All four sides are congruent
- Diagonals bisect 90° angles
- Diagonals DO NOT bisect 90° angles
3 Answers:
B) Diagonals bisect each other and diagonals are equal in lengthD) The opposite sides are congruentG) Diagonals do not bisect the 90 degree angles==========================================================
Explanation:
Let's go through the answer choices one by one
A) This is false. If the diagonals were perpendicular, then we would have a square. The diagonals are also perpendicular for any rhombus and for any kite. For any non-square rectangle, the diagonals are not perpendicular.B) This is true. The diagonals bisect each other because we're dealing with a parallelogram. Any rectangle is a parallelogram. For any rectangle, the diagonals are equal in length as well. We can use SAS congruence theorem to prove this.C) This is false. The first part is true, but the second part contradicts what choice B is saying.D) This is true. The opposite sides of any rectangle are congruent, and they are parallel. E) This is false. Imagine a really stretched out or elongated rectangle. So not all four sides of a rectangle are the same length. If they were, then we would have a square.F) This is false. The diagonals do not bisect the angles unless we're dealing with a square. Again imagine stretching out a rectangle to make it very elongated. G) This is true since choice F was false.The statements always true about rectangles are Diagonals bisect each other in diagonals are equal in length, Opposite sides are congruent, Diagonals DO NOT bisect 90° angles.
What is Rectangle?Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles.
Diagonals are not perpendicular in rectangles. So first statement is wrong.
Diagonals bisect each other in rectangles and the length of the diagonals are equal.
Since the length of diagonals are equal, third statement is wrong.
Opposite sides of a rectangle are equal and are thus congruent.
In a rectangle, only opposite sides are congruent and equal. All the four sides are not equal and are thus not congruent.
Diagonals of a rectangle does not bisect 90° angles.
Hence the correct statements are shown.

2 1/5 - 5/6 =
Answer:
2 1/5 - 5/6 = 41/30
Step-by-step explanation:
Turn the denominator to be the same because if the denominator is not the same so you can't subtract neither can you add.
Next find the least common multiple of both denominator (5, and 6) and ask yourself what time the denominator would give you the least common multiply you got.
1/5 x 6/6 = 6/30 and 5/6 x 5/5 = 25/30
Your expression now would be 2 6/30 - 25/30
You can't subtract 6 from 25 so you have to turn the proper fraction into a improper fraction
2 6/30 = 2 x 30 + 6 = 66/30. 25/30 = 0 x 0 + 25 = 25/30.
Your new expression would be:
66/30 - 25/30
Now you can subtract 66 - 25 and you get 41
Therefore the correct answer is 41/30 you can not simplify the answer because the numerator is a odd number and the denominator is a even number.

If y varies directly as x and y = -7 when x = -28, find y when x = 20.
PLZ help ASAP
Answer:
5
Step-by-step explanation:
y ∝ x
y = k times x
where 'k' is constant
substitute y for -7 and x for -28
-7 = k times -28
-7 = -28k
Divide through by -28
[tex]\frac{-7}{-28}[/tex] = [tex]\frac{-28k}{-28}[/tex]
= [tex]\frac{1}{4}[/tex] =k
formula y = [tex]\frac{1}{4}[/tex] times x
y = [tex]\frac{1}{4}[/tex] times 20
y = 5
By using the proportionality relation, at x = 20 the value of y will be 5.
Calculations for the value of y from the proportional relation:
Given in the question → y ∝ x
y = kx
Here, k = Proportionaility constant
It's given, when x = -28, value of y = -7
By substituting these values in the expression,
-7 = k(-28)
[tex]k=\frac{-7}{-28}[/tex]
k = [tex]\frac{1}{4}[/tex]
Therefore, given expression for the proportional relation will be,
[tex]y=\frac{1}{4}x[/tex]
If x = 20, we have to calculate the value of y,
Substitute x = 20 in the same expression,
[tex]y=\frac{1}{4}(20)[/tex]
y = 5
Therefore, for the value of x = 20, value of y will be 5.
