Answer:
70
Step-by-step explanation:
the red lines mean the two sides are equal
so its an isosceles triangle meaning the two angles other than the 40° one are equal
the inner angles of a triangle must add up to 180
so 180-40 = 2x
140 = 2x
x = 140/2 = 70
Answer:
it should be step 2
Step-by-step explanation:
Change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.
<h3><u>Solution:</u></h3>
Given that
A clogged bathtub drains at a constant rate.
The amount of water in the bathtub changes by –3.75 gallons in one hour.
Need to determine change in the amount of water in the bathtub after 13 hour.
Change in amount of water in bathtub in one hour = -3.75 gallons
As given that clogged bathtub drains at a constant rate, so
Change in amount of water in bathtub in 13 hours = 13 x Change in amount of water in bathtub in 1 hours
=> Change in amount of water in bathtub in 13 hours = 13 x ( -3.75 ) = -48.75 gallons
Hence change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.
Answer:
2/3a^5
Step-by-step explanation:
we know that 2/7x2/7x2/7 = 8/27
a^15 cube will be a^5
because we know (2^3)^2 = 2^6
so (a^5)^3 = a^15
2/3a^5
Well, since point A represents the center, and B represents a point on the outer line of the circle, segment AB would represent the radius, since the radius represents the length from the center to the outside of a circle
Hope this helps
