Answer:
30 units
Step-by-step explanation:
Look at the top layer of the prism, The width is <em>3</em> units the length is <em>5</em> units.
Take and multiply <em>LxW</em> <em>3 x 5</em> which is <em>15</em>.
Sense the height is <em>2</em> multiply <em>15</em> times <em>2</em> to get <em>30</em>.
<u><em>Hope this helps have a good day!</em></u>
Answer:
Okay so, we know that Theta =10°
Opposite=7ft
Adjacent= x ft
And then
Tan 10=7/x
Hence
X=7/tan10
X=39.69897 39. 7 ft
I Hope that i explained well
52) 115-3=112 that were given away
Now divide 112 by each, seeing if they give you a non mixed number.
The only one that would give you a full number would be 28. So there are 28 kids in his class.
54) 19-4=15
Now double 15 since he sold half, so he started with 30 stamps originally.
56) 500-2*=324
-2*=-176
age=88
Answer:
see explanation
Step-by-step explanation:
This is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16
= ( 4
)² ⇒ a = 4
1 = 1² ⇒ b = 1
Hence
16 - 1
= (4 )² - 1²
= (4 - 1)(4 + 1)
4 - 1 ← is also a difference of squares and factors as
(2x² - 1)(2x² + 1)
Thus
16 - 1
= (2x² - 1)(2x² + 1)(4 + 1 )
