Answer: The density of a gallon of water will therefore = 3.79 kg/m^3
Step-by-step explanation:
1 liquid gallon = 0.00379 cubic metre
5 gallons = 5 × 0.00379 cubic metre
5 gallons = 0.01895 m^3
Since the liquid is water and density of water is approximately 1000 kg per cubic meters
The density of 5 gallons of water will be 1000 × 0.01895 = 18.95 kg/m^3
The density of a gallon of water will therefore equal to 1000 × 0.00379 = 3.79 kg/m^3
Answer:
60(10 -7) - (-26/2)^2 (do the problems in the parenthesis)
60(3) - (-13)^2 ( multiply 60 and 3 and then square -13)
180- 169 (subtract)
11
It is a representation of a number
A straight angle measures 180º.
A triangle's interior angles also measure 180º.
The angle measuring 130º is complementary to the corresponding interior angle, so that interior angle plus 130 has to equal exactly 180º.
180 - 130 = 50º
45 + 50 = 95º, so subtract that from 180 to find the measure of the last interior angle of the triangle.
180 - 95 = 85º
That angle of 85º is complementary to the other outside angle, n, and to find that subtract 85 from 180.
180 - 85 = 95º
n = 95
Hope this helps!
Slope is change in y over change in x.
Change in y is -9
Change in x is +12
So -9/12 or -2/3
Answer -2/3
