Answer: Choice D. [tex]6.44 \times 10^{-4}[/tex]
========================================================
Work Shown:
We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents
This is what the steps could look like
[tex]\left(9.2 \times 10^{-9}\right)\times\left(7 \times 10^{4}\right)\\\\\left(9.2\times7\right)\times\left(10^{-9} \times 10^{4}\right)\\\\\left(64.4\right)\times\left(10^{-9+4}\right)\\\\\left(6.44\times 10^{1}\right)\times\left(10^{-5}\right)\\\\6.44\times\left(10^{1}\times 10^{-5}\right)\\\\6.44\times\left(10^{1+(-5)}\right)\\\\6.44\times 10^{-4}\\\\[/tex]
The final result is in scientific notation as the coefficient c is restricted such that [tex]0 \le c < 10[/tex]

|-5| |-(-5) | Is this equal or which one is more ?
Answer:
Equal
Step-by-step explanation:
The absolute value of any number is the same as the value between the lines, but instead, it is positive. The lines (|x|)represent the amount of units/numbers |-5| and |-(-5)| is away from 0. They are both 5 numbers away from it, so it is equal.
Answer: Yes it is equal.
Step-by-step explanation:
when a number is an absolute, always assume it is possitive number.
Example: l-2l = 2 or l2l = 2

Is 4 to 7 the same as 7 to 4? explain why or why not
Answer:
Just say, "No, 7 to 4 is not the same as 4 to 7. I don't know why, but I just know because you taught me it wasn't."
Step-by-step explanation:
It worked for me lol
Answer:
4 to 7 is pretty much 4 divided by 7 which = 4/7 and 7/4 is 1 3/4. which is obviously greater. So they both equal different answers.

choose the more precise measurement from the pair 54.1 cm and 54.16 cm.
Answer:
a
Step-by-step explanation:
Precision means that a measurement using a particular tool or implement produces similar results every single time it is used. For example, if you step on a scale five times in a row, a precise scale would give you the same weight each time. In math and science, calculating precision is essential to determine if your tools and measurements work well enough to get good data. You can report precision of any data set using the range of values, the average deviation, or the standard deviation.

find three consecutive integers for which 3 times the sum of the first and the third is -342
Answer:
The integers are -58, -57, -56.
Step-by-step explanation:
The difference between two consecutive integers is 1.
If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.
Integers: x, x + 1, x + 2
The sum of the first and third is: x + x + 2
3 times the sum of the first and third is: 3(x + x + 2)
That product equals -342.
3(x + x + 2) = -342
3(2x + 2) = -342
Divide both sides by 3.
2x + 2 = -114
Subtract 2 from both sides.
2x = -116
Divide both sides by 2.
x = -58
x + 1 = -57
x + 2 = -56
The integers are -58, -57, -56.

Please help me choose if they are a yes or no.
Answer:
A)yes
B)yes
c)no
d)yes
e)yes
f)no
Part A
Answer: YesThis is the same as saying 2(AB+BC). A more written out version is AB+BC+CD+DA, though it's not needed since the opposite sides are congruent (AB = CD and BC = DA)
====================================================
Part B
Answer: YesThe diagonals of any parallelogram bisect each other. They cut each other in half.
====================================================
Part C
Answer: NoThe adjacent sides of a parallelogram aren't always equal in length. It only happens when we have a rhombus.
====================================================
Part D
Answer: YesThe angles mentioned are alternate interior angles. They are congruent due to AD and BC being parallel.
====================================================
Part E
Answer: YesWe can use the SSS or SAS congruence theorem to prove these triangles are congruent.
====================================================
Part F
Answer: NoThese are adjacent angles that aren't always the same measure. Diagonal AC does not bisect angle DAB. This only happens if we had a rhombus.

Can anyone help me solve this question
9514 1404 393
Answer:
a=2√2+4b = 3Step-by-step explanation:
√24 = 2√6
√48 = 4√3
Then the sum is ...
√24 +√48 = 2√6 +4√3
Factoring out √3, we have ...
= (2√2 +4)√3
Matching this to the form a√b, we have
(2√2+4)√3 ⇒ a=2√2+4, b = 3
which of the following statements does not represent the same value as the others
the absolute value of negative 9
the absolute value of 9
the distance between 0 and -9
the opposite of 9
Answer:
the opposite of 9
Step-by-step explanation:
the absolute value of nagative 9, is positive 9.
the absolute value of postive 9, is postive 9.
the distance between 0 and nagative 9 on a line would be a count of postive 9.
the opposite of postive 9 is negative 9 (the only one with a diffrent outcome)

Which list shows the circles in order from greatest area to least area?
A. Circle Z, circle Y, circle X
B. Circle Y, circle Z, circle X
C. Circle X, circle Z, circle Y
D. Circle X, circle Y, circle z
Answer:
C. Circle X, circle Z, circle Y
Step-by-step explanation:
Given
Circles X, Y and Z
Required
Order from greatest to highest
First, we need to simplify the given areas;
For Circle X
[tex]A = 9\pi[/tex]
Take [tex]\pi[/tex] as 3.14
[tex]A = 9 * 3.14[/tex]
[tex]A = 28.26[/tex]
For Circle Y
[tex]A = \frac{\sqrt3}{2}[/tex]
This gives
[tex]A = \frac{1.732}{2}[/tex]
[tex]A = 0.866[/tex]
For Circle Z
[tex]A = 27.5[/tex]
By comparing the above areas;
X has the largest area; followed by Z and then Y
Hence,

Three boys were running around the track. The first can run 1 lap in 15 min. The second can run 1 lap in 25 min. and the third can run a lap in 10 min. If the boys start running at 12:45, what time will all 3 boys pass each other again?
Answer:
At 15:15
Step-by-step explanation:
Given,
the 1st boy can run a lap in 15 minutes
the 2nd boy can run a lap in 25 minutes
the 3rd boy can run a lap in 10 minutes
Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.
[tex]L.C.M.[/tex] of 15,25 & 10 = 150
So,they will pass each other after 150 minutes or 2 hours & 30 minutes.
If we add it with 12:45 we'll get 15:15 or 3:15 pm
