What is the length of a diagonal of a cube with a side length of 3 cm?
StartRoot 18 EndRoot cm
StartRoot 27 EndRoot cm
StartRoot 33 EndRoot cm
StartRoot 38 EndRoot cm
Answer:
27
Step-by-step explanation:
d^2=x^2+y^2+z^2, and since this is a cube, x=y=z=s, and we are told that s=3
d^2=3s^2 and s=3
d^2=3(3^2)
d^2=3(9)
d^2=27
d=√27
StartRoot 27 EndRoot cm
Answer:
27
Step-by-step explanation:
3×√3 = 5.196
√27 = 5.196

There are two questions :v
Answer:
Step-by-step explanation:
One
v^2 - 16
This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.
The square root of v^2 = v
The square root of 16 = 4
You get (v + 4)(v - 4)
Let's see what happens when you expand it.
v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16Look what happens when you add these 4 terms together.
v^2 - 4v + 4v - 16v^2 - 16is what is left. The two middle terms cancel out.
Two
This one is a perfect square
w^2 + 16w + 64
(w + 8)(w + 8)
Notice both factors are the same. You might wonder how I new that.
w^2 is a perfect square so take the square root. .... v
64 is a perfect square so take the square root ..... 8
Now you have to work backwards to see if it is right.
w*w = w^2w*8 = 8w8*w = 8w8^2 = 64Adding you get w^2 + 16w + 64 which is what you started with.

Answer:
A"(-6, 3)
B"(-9, 0)
C"(-5, -1)
Step-by-step explanation:
We presume the first transformation is a translation 4 units right and 1 unit up:
(x, y) ⇒ (x+4, y+1)
The second transformation negates the x-coordinate, so the two transformations together have the rule ...
(x, y) ⇒ (-(x+4), y+1)
Then the transformed points are ...
A"(-6, 3)
B"(-9, 0)
C"(-5, -1)
I need help on this and the first person who answer correctly gets a BRANILIST
Answer:
first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml
Step-by-step explanation:
Find the area of the shaded region. Use 3.14 for pi.
Answer:
326
Step-by-step explanation:
First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.

WHAT DIVIDED BY 9 = -5
Answer:
−1.8
Step-by-step explanation:
gimme the answer for 10 points :)
Given:
The table of values.
v and x are in direct proportion.
To find:
The formula connecting v and x.
Solution:
(a)
v and x are in direct proportion.
[tex]v\propto x[/tex]
[tex]v=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting v=13.6 and x=32.64, we get
[tex]13.6=k(32.64)[/tex]
[tex]\dfrac{13.6}{32.64}=k[/tex]
[tex]\dfrac{5}{12}=k[/tex]
Putting the value of k in (i), we get
[tex]v=\dfrac{5}{12}x[/tex]
Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].
(b)
Putting v=n and x=8.16, we get
[tex]n=\dfrac{5}{12}(8.16)[/tex]
[tex]n=3.4[/tex]
Therefore, the value of n is 3.4.

PLEASE HELP
B. Engine Repair is more likely to be paid for with a credit card. Option B is correct
It is to be determined Which of these purchases is more likely to be paid for with a credit card
Parking fee B. Engine repair C. Soda D. Lotto ticket
A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.
Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.
Thus, B. Engine Repair is more likely to be paid for with a credit card. Option B is correct
