Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α

Answer:
A is $0.45 B is 2 ounces
Step-by-step explanation:
A when you divide the cost by the ounces or $5.40 by 12 ounces you get $0.45 per ounce.
B $0.45 times 2 equals 90 cents and you cannot go over 1 dollar.
C you should be to do along with D with this information.
Answer:
15 . Undefined
16. undefined
Step-by-step explanation:
We have the perimeter of first dimension 2(8 + 4) = 24;
The perimeter of the second dimension is 2( 8 + 54 + 4 + 54 ) = 240
We calculate p/100 = 24/240;
Then p/100 = 1/10;
p = 100/10;
p = 10;
Finally, 10% is the answer.
Answer:
38.75
Step-by-step explanation:
perimeter = 2(15.6+3.8) =38.8
lower bound = the smallest value that would round up to the estimated value =38.75
