a materials scientist has 56 pounds of a liquid. she uses most of the liquid to fill 7 beakers. The remaining liquid fill 1/9 of
an 8th beaker. How many ponds of liquid is in one full beaker
1 answer:
Answer:
7.875 pounds
Step-by-step explanation:
Assuming the beakers are the same size, and each beaker takes in x pounds.
Then for seven beakers we have;
x × 7 = 7x pounds
For the eight beaker;
1/9 × x= 1/9x pounds
Therefore;
7x + 1/9x = 56 pounds
63x + x = 56 ×9
64 x = 504
x = 504/64
= 7.875 pounds
Therefore; one full beaker takes in 7.875 pounds when full

362 is the 70th term of the sequence.
Answer:
45
Step-by-step explanation:
6 to the power of 2 + 3 to the power of 2
6² + 3²
(6 × 6) + (3 × 3)
36 + 9
