Answer:
we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.
Step-by-step explanation:
Given the expression
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}=\frac{1\cdot \:\:1\cdot \:\:1\cdot \:\:1}{5\cdot \:\:5\cdot \:\:5\cdot \:\:5}[/tex]
[tex]=\frac{1}{5\cdot \:5\cdot \:5\cdot \:5}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Checking options B and C:
Option B
[tex]\left(5^{-4}\right)^0=1[/tex]
Option C
[tex]\frac{5^1}{5^4}=\frac{5}{625}=\frac{1}{125}[/tex]
Thus, options B and C are not equivalent!
Checking Option A
Option A
[tex]\left(5^{-2}\right)^2[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(5^{-2}\right)^2=5^{-2\cdot \:2}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Now, checking option D
Option D
[tex]5^2\cdot \:5^{-6}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]5^2\cdot 5^{-6}=5^{2-6}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Therefore, we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.

Please give me the correct answer
Answer:
it's answer is 3.75
Step-by-step explanation:
Hypotenuse (h) = 6.25
Perpendicular (p) = 5
base (b) = ?
By using Pythagoras theorem we get
b = √ ( h² - p²)
= √( 6.25)² - 5²
= √ 14.0625
= √(3.75)²
= 3.75
Hope it will help:)❤
By Pythagoras theorem, a^2+b^2=c^2
The answer is 3.75

What is the slope of the line graphed on the coordinate plane?
Put your answer in the box
Answer:
-8
Step-by-step explanation:
As we know, slope is rise over run. We count up and over until we get to the next dot. To get to the next dot, we count 8 up and -1 over (since we go to the left, not the right). We can put this in a fraction (rise/run). That gets us 8/-1, which can be simplified to -8.

Which sentence best describes the equation: z = 18 + 96
Answer:
A
Step-by-step explanation:
Z is the same as the answer to the equation so if you add 18 and 96 together you will get z
also sum means adding
Answer: a
Step-by-step explanation:
the answer has addition and it says 18+96=z so i believe that theyre trying to say that whatever you add is gonna equal z so i believe the correct answer is a (:
Find the perimeter of a 35° slice of pizza that has a radius of 8 inches.
9514 1404 393
Answer:
20.9 inches
Step-by-step explanation:
The perimeter length is the sum of the lengths of the two straight edges and that of the curved edge.
P = r + r + rα . . . . . where α is the central angle in radians
35° is (35°/180°)π radians, about 0.6109 radians
Then the perimeter is ...
P = r(2 +α) = (8 in)(2 +0.6109) ≈ 20.9 in
The perimeter of the slice is about 20.9 inches.

form of the line that passes through the
point (2,-2) and is perpendicular to the
line y =2/5x+2
A.
y= 2/5x - 7
B.
y=-2/5x+7
C.
y=5/2x-3
D.
y=-5/2x+3
Answer:
A
Step-by-step explanation:
If you plug in (2, -2) to each one, you would get -2= 5/2(2)-7
5/2 = 2.5 and 2.5 x 2 = 5, 5-7 does in fact equal the Y which is -2

Angle on a straight line is 180 degrees. Angle ABC is 90. You're given angle FBE as 47. So, it is 180-(90+47)= 43. That's the angle ABF.
Find the value of x answer: A.4 B.8 C.6.6 D.6
Answer:
The value of x is 4
Step-by-step explanation:
From what we can see in the diagram , the bigger triangle has lengths that are twice the smaller one
Thus, mathematically;
2(3x-4) = 16
3x - 4 = 8
3x = 8 + 4
3x = 12
x = 12/3
x = 4

Joe is arranging video games on shelves. He has 48 playstation games and 36 xbox games, Each shelf will have the same number of playstation and xbox games. If Joe must place all of the videogames on shelves, what are the possible number of shelves Joe will use?
Answer:
2 shelves
3 shelves
4 shelves
6 shelves
12 shelves
Step-by-step explanation:
playstation games = 48
xbox games = 36
Each shelf will have the same number of playstation and xbox games.
Find the common multiples of 48 and 36
48 = 2, 3, 4, 6, 8, 12, 16, 24, 48
36 = 2, 3, 4, 6, 9, 12, 18, 36
The common multiples are 2, 3, 4, 6, and 12
Therefore, the possible number of shelves Joe will use is
2 shelves
3 shelves
4 shelves
6 shelves
12 shelves

Z + y + 0 = z + y equals to what?
Answer:
y=0/0
Step-by-step explanation:
Step 1: Add -y to both sides.
y+z+−y=y+z+−y
z=z
Step 2: Add -z to both sides.
z+−z=z+−z
0=0
Step 3: Divide both sides by 0.
0/0=0/0
y=0/0
Factor the expression.

O A
(4x + 7)(4x - 7)
B. (7x + 4)(7x-4)
C. (7x-4)(7x-4)
OD. (4x-7)(4x - 7)
Step-by-step explanation:
Difference of squares: A² - B² = (A + B)(A - B).
Therefore 49x² - 16 = (7x)² - (4)² = (7x + 4)(7x - 4).
The correct answer is Option B.

Noah ran 2 1/2 miles in 3/5 hour. How far does he run in 1 hour?
Step-by-step explanation:
0.6 hours = 2.5 miles
=> 1 hour = 2.5 miles * (1/0.6) = 4.16 miles.
Hence Noan runs 4.16 miles in 1 hour.
(or 25/6 miles)
