4. The sum of iwo numbers is 36. Twice the first
Ludmilka [50]

Answer:

  14 and 22

Step-by-step explanation:

If x is the first number, then 36-x is the second. We are told that ...

  2x -(36-x) = 6 . . . . twice the first less the second is 6

  3x = 42 . . . . . . . . . add 36

  x = 14

  (36 -x) = 22

The numbers are 14 and 22.

6. If you spun the spinner below, what are the odds that you will spin an
denis23 [38]

If you mean that is a 4 digit number then here is your answer.

Answer:

1:1

Step-by-step explanation:

So there is 1000 to 9999. That includes 9999-999= 9000 numbers. Since each number it is either a odd number or an even number, we can say that it is 1:1 There would be 4500 odd and 4500 even numbers. Every even number is followed by an odd number. for example: 1000-1001 1002-1003 1004-1005

so on so you would get to the point that you get to 9998-9999

Hope it helped you!

Find the exact value by using a half-angle identity. . cos(5π/12).
vodka [1.7K]
<span>First of all in order to find the exact value by using a half angle identity we will do
cos(5π divided by 12)

=cos (5π divided by 6) divided by 2
= ± Under root[(1+cos (5π divided by 6) divided by 2]
Now we will consider + sign because 5π divided by 12 is in quadrant. where cos>0
so the solution is [(1- Under root 3 divided by 2) divided by 2] 
We will ignore the negative sign
I hope it helped.</span>

The sculpture consists of five identical prisms. JD says the surface area of the sculpture is 44 times the surface area of one p
larisa86 [58]
The complete question in the attached figure

we know that
(see the attached figure n 2 to understand the problem)
[the surface area of one prism]=2*[x*x]+2*[x*y]+2*[x*y]----> 2x²+4xy
[the surface area of the sculpture]=2*[5*x*y]+2*[3*x*x]+2*[3*x*y]--> 6x²+16xy

now
<span>JD says the surface area of the sculpture is 4 times the surface area of one prism
</span>[the surface area of the sculpture]=4*(2x²+4xy)---> 8x²+16xy

we compare the value that JD says with the real value
(8x²+16xy) > (6x²+16xy)
the value that JD says is <span>greater in comparison with the real value
</span>This is because <span>JD should also subtract the areas of eight hidden surfaces.

the answer is 
</span>JD should also subtract the areas of eight hidden surfaces<span>

</span>
