Answer:
110°
Step-by-step explanation:
t+(t+10)+(t+20)=180
t+t+10+t+20=180
3t=180-10-20
3t=150
t=50°
t+20=50+20
=70
180-70=110°

Answer:
an=12−1.5n
Step-by-step explanation:
The first term is 10.5.
The common difference is ...
9 - 10.5 = -1.5
The n-th term can be described by ...
an = a1 +d(n -1)
an = 10.5 -1.5(n -1) = 10.5 -1.5n +1.5 . . . . eliminate parentheses
an = 12 -1.5n
Answer:
the answer is 180 feet
Step-by-step explanation:
because it is a square all sides are equal so the distance is between two lines so you only have to add two sides: (90+90=180).
Answer:
Planter 1 is 48 meters cubed
Planter 2 is 24 meters cubed
Total volume = 72
Step-by-step explanation:
The formula for the volume of a rectangular prism is length times width times height. So, 4*4*3. This equals 48. If the other planter is half the volume, divide 48 by 2 to get 24 meters cubed. To find the total area add both results to get a total of 72 meters cubed.
