C
5 is 1/3 of 15 and 1 is 1/3 of 3 so C would be correct
Answer:
What is the number being compared to
Step-by-step explanation:
Answer:
m<0 = 50
Step-by-step explanation:
The opposite angles in an isosceles trapezoid are equal, so <T = <A
and <B = <O
We know the sum of all 4 angles has to be 360 since it is a quadrilateral
<T+<A + < B + <O = 360
Substituting what we know, and what we want to know
<T+ <T + <O <+O = 360
Combining like terms
2<T + 2 <0 = 360
2( 130) + 2<0 = 360
260 + 2< O = 360
Subtract 260 from each side
260-260 + 2< O = 360-260
2<O = 100
Divide by 2
2/2<O = 100/2
<0 = 50
I decided to put them as decimals. 5/12 is equivalent to 0.416. Then there is a decimal already there, which is also 0.416. Then there is 42% which as a decimal is 0.42.
In order it is
<u><em>0.416, 0.416</em></u><em>, and 0.42</em>
The first two are equivalent :P
Answer:
x=15, y=11 or x=11, y=15
Step-by-step explanation:
no quick or easy way to solve sys of eqns like this:
(1) x+y=26
and
(2) xy=165
rearranging (1),
y=26-x
substituting into (2),
x(26-x)=165
expanding n rearranging,
26x-x^2=165
x^2-26x+165=0
(x-15)(x-11)=0
x-15=0 or x-11=0
x=15 or x=11
y=26-15 or y=26-11
y=11 or y=15
so x=15, y=11
or x=11, y=15
