Answer : 110 degree
To find angle 1 , we apply outside angle theorem Lets name each point Measurement of arc EF=280 degrees
Measurement of arc GH = 60
Angle D = angle 1
Please refer to the theorem attached below
Now we plug in the values
angle 1 = 110
Measurement of angle 1 = 110 degrees
Step by step explanation
4n-8=5
4n= 5+8
4n=13
4/4 n = 13/4
n= 13/4
Answer:
no u
Step-by-step explanation:
Direct Proportion functions look like this:
y=kx
'k' is the constant of proportionality and in this case its 7.5 or 15/2.
--------------------------------------------
When x=1, y=7.5
When x=2, y=15
When x=3, y=22.5
Therefore y is directly proportional to x.
--------------------------------------
DIRECT PROPORTION EXPLAINED:
Say a football costs £7.50. If you buy one football you'll have to pay out £7.50, but if you you buy two footballs you'll have to pay out £15.00. Therefore the cost of the football(s) is directly proportional to the amount of footballs you buy. C=cost, f=football(s) and C<span>∝f, therefore C=kf, but as k=7.5, C=7.5f.
INVERSE PROPORTION EXPLAINED:
If it were to take 8 hours for one bricklayer to set up a wall, how long would it take for two bricklayers to set up a wall? The answer in this case would be 4 hours.
T=time to set up a wall
b=bricklayer(s)
Therefore T</span><span>∝1/b, and T=k/b. In this case k=8 so T=8/b.
When b=1, T=8.
When b=2, T=4.
We'd say that the time it would take for bricklayers to set up a wall would be inversely proportional to the amount of bricklayers available.</span>
Answer:
20%
Step-by-step explanation:
20/25 = blue
This means 5/25 of the balls in the bag are NOT blue
(25-20 = 5)
We need to convert 5/25 to a percentage
% = per cent
"per" means "out of"
"cent" means "one hundred"
so
20/100 = 20%
