Answer:
m(arc AC) = 72°
m(arc BD) = 108°
m∠DEB = 90°
Step-by-step explanation:
Ratio of the measure of arc AC, arc BC, arc BD and arc AD = 4 : 2 : 6 : 8
Since, m(arc AC) + m(arc CB) + m(arc BD) + m(arc AD) = 360°
By the property of ratio,
Measure of arc AC = 
= 
= 72°
Measure of arc BD = 
= 
= 108°
Measure of ∠DEB = 
= 
= 90°
Answer:
our inputs are 3 & 1/2
Step-by-step explanation:
the ? is the slope and the slope is equal to 1/2 so
?=1/2
the point slope formula is
(y-y1)=m(x-x1) (x1,y1)--> a point on the line m--> slope
so we chose (x1,y1) as (3,0)
when we plug that in we get
y-0=1/2(x-3)
so our inputs are 3 & 1/2
Answer:The slant height of the top is 5 m, and the height of the cylinder is 9 m. Find the distance between P and Q, to the nearest cm. 0 height of small triangle.
Answer:
4%
Step-by-step explanation:
Since she first goes down 20% you would do 3000 times 20 which is 60000 and divided by 100 which is 600 and you would subtract 600 from 3000 which is 2400 and then you would multiply that by 30 which is 72000 and then you would divide by 100 which is 720 and add that to 2400 which is 3120 and to find the percent change from 3000 to 3120 you would subtract 3120 by 3000 which is 120 and you would divide that by 3000 which is 0.04 and multiply that by 100 which is 4 so the percent change would be 4%
