Find a common denominator. The lowest one would come from you multiplying 2/5 by 4 on each side and 1/4 by 5 on each side. You are left with 8/20 and 5/20, added together would be 13/20.
Answer:
multiply
Step-by-step explanation:
all you need to do is multiply 2×1×1
Answer:
y = -2x + 10
Step-by-step explanation:
8x + 4y = 40
4y = -8x + 40
y = -2x + 10
Answer:
25.05 miles per week
Step-by-step explanation:
We know that,
1 mile = 1760 yards
⇒ 920 yards = 0.522 mile
1 week = 168 hour
We need to find ts speed in miles per week.
Speed = distance/time
So, the speed of the object is 25.05 miles per week.
Answer:
Step-by-step explanation:
I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.
11) tan45 = x/13 x = 13
cos45 = 13/y y = 13√2
12) sin30 = 4/x x = 8
tan30 = 4/y y = 4√3
13) sin60 = 21/x x = 21(2/√3) = 42/√3
y = xcos60 = (42/√3)(1/2) = 21/√3
14) cos45 = x/22 x = 22/√2
sin45 = y/22 y = 22/√2
15) Height = 24sin30 = 12
cos 45 = 12/x x = 12/√2
tan45 = y/12 y = 12
cos30 = z/24 z = 24(√(3)/2) = 12/√3
