One solution let's find that
Answer:
20%
Step-by-step explanation:
and 60 and 20 u get 80 then 100-80 would give u 20 idk this how id assume u do it
STEP 1:
Triangles= 180°
Other Angles= 7:13= 7x + 13x
Add all the angles to equal 180°
140° + 7x + 13x= 180°
combine like terms
140° + 20x= 180°
subtract 140 from both sides
20x= 40
divide both sides by 20
x= 2
STEP 2:
substitute x value to find other two angles
7x= 7(2)= 14° one angle
13x= 13(2)= 26° other angle
CHECK:
140° + 14° + 26°= 180°
140 + 40= 180
180= 180
ANSWER: The other two angles measure 14° and 26°.
Hope this helps! :)
Please note that in such questions, the ":" stands for ratio which in turn stands for divide. Thus, the given expression which is:
will become:
.....(Equation 1)
Now, we know that 3.8 can be rewritten as 
. Also, we know that the mixed fraction 
can be re-written as:
Using the above two expressions in (Equation 1) we get:
Cross-multiplication gives:
Or c=0.25
Thus, we may write the value of c as either the decimal 0.25 or the fraction 
.
Answer:
It will take at least 15 weeks
Step-by-step explanation:
12w+31 ≥ 205
Subtract 31 from each side
12w+31-31 ≥ 205-31
12w ≥ 174
Divide each side by 12
12w/12 ≥ 174/12
w ≥ 14.5
Rounding up to the nearest integer
w ≥ 15
It will take at least 15 weeks
