Answer:
1
Step-by-step explanation:
Keep-Change-Flip
4/12 (keep) × (change) 12/4 (flip)
4/12 × 12/4
4 × 12 = 48
12 × 4 = 48
48/48 = 1
I saw this same type of question and page but with different numbers just 5 minutes ago...
Anyway here’s the answers:
1) Complementary
3x+1+44=90
3x+45=90
3x=45
x=5
2) Vertical
Ignore everything about the work. The answer is 120 degrees because they’re vertical angles.
3) Supplementary
15x-5+110=180
15x+105=180
15x=75
x=5
And I can’t see the last question clearly
The maturity value is the principal value together with interest due.
.. mv = P +Prt
.. = 5350*(1 +0.085*120/360) . . . . . . year is 360 days for "ordinary interest"
.. ≈ 5501.58
The maturity value is $5501.58.
The answer is
AB = 6.
External value x (external value + internal value) =
External value x (external value + internal value) of the other side
Substitute, transpose, and simplify.
TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4
To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6
14.4, 120% of 12 is 100+20, 12+2.4 is 14.4
