Answer:
The specific gravity of kerosene is 0.82
Step-by-step explanation:
Let
x -----> the weight in grams of a cubic centimeter of Kerosene
y ----> the weight in grams of a cubic centimeter of water
z ---> the specific gravity of a substance
so
we have
substitute the values
F(n)=f(n+1)=f(n+1)-5 because in the formula you are subtractinng
Answer:
3.45
Step-by-step explanation:
15 percent of 23
15 percent to decimal = 0.15
23 x 0.15 = 3.45
Answer:
multiply the first equation by 2
Step-by-step explanation:
24x + 36y = 72
-16x + 8y = 80
48x + 72y = 144
-48x + 24y = 240
96y = 384
y = 4
24x + 36(4) = 72
24x + 144 = 72
24x = -72
x = -3
(-3, 4)
Complementary angles are angles that measure up to 90 degrees.
To find the measures of the two angles, divide 90 by two to say two angles of 45 degrees. Now divide 14 by 2, which you get 7 with. Now add 7 to 45 and subtract it from 45 as well, to get 52 and 38.
The measures of the angles are 52 degrees and 38 degrees.
