I’m pretty sure surface area is all the sides multiples then added
I’m going to assume the length is 10, width is 4, and height is 3
You would find the base of the rectangle which is the same as the top and that would be 80 (because 10 multiples by 4 for the base and top)
Then the ends which is 3x4= 12 and you have to sides so the total is 24
And lastly the sides which is 10x3= 30 and you have 2 sides so it’s really 60
In total you have 60+24+80= 164cm

What is the distance in meter of an object that has an angular diameter of 30 arcseconds and a linear diameter of 10 cm?
Leya [2.2K]

Answer:

Distance of object = 0.0144 meter

Step-by-step explanation:

Given:

Angular diameter = 30 arcseconds = 30[100 / 3600]

Length of diameter = 10 cm

Find:

Distance of object

Computation:

Distance of object = [(2)(a)][TanФ / 2]

Distance of object = [(2)(10)][Tan(300 / 7200]

Distance of object = [20][Tan 0.04167]

Distance of object = [20][0.00072]]

Distance of object = 0.0144 meter

Additive Inverse Property<br><br> 0 = 5c + <br><br> what is the missing number?
Vilka [71]

Answer:

Hi there!

Your answer is:

-5c

The full equation is:

0= 5c + (-5c)

Step-by-step explanation:

The additive inverse is whatever two numbers, when added, equal 0. We have a positive 5c here. To get rid of 5c, we must subtract 5c from 5c

I hope this helps!

Out of the 4, which is the solution?​
yarga [219]

Answer:

x=0

Step-by-step explanation:

You can substitute 2-6y in for x to create

9y +2(2-6y) = 3

9y + 4 -12y = 3

-3y = -1

y=1/3

Then plug in y for x=2 -6y

x= 2-6(1/3)

2-2=x

x=0
