Answer: 
==========================================================
Work Shown:
Focus entirely on triangle ABD (or on triangle BCD; both are identical)
The two legs of this triangle are AB = 8 and AD = 8. The hypotenuse is unknown, so we'll say BD = x.
Apply the pythagorean theorem.
So that's why the diagonal BD is exactly 
units long
Side note: 
Answer:
formula for volume is length × width × height.
The answer is they are reciprocal.
(1) Express both equations in the slope-intercept form: y = mx + b, where m is slope:
<span> 8x - 9y = 5
9y = 8x - 5
y = 8/9x - 5/9
m1 = 8/9
</span><span>9x - 8y = 1
8y = 9x - 1
y = 9/8x - 1/8
m2 = 9/8
So, m1 = 8/9 and m2 = 9/8. They are reciprocal</span>
Answer:
1715 hours
Step-by-step explanation:
7hours ×5 days= 35 horus a week
35 hours a week × 49 weeks= 1715 hours a yr.
Answer:
x=24
Step-by-step explanation:
you need 300.
10x + 60?
10 x 3 = 300
300 - 60 = 240
300 = (10 x 24) + 60
