Answer:
t = -14
Step-by-step explanation:×
I did 4+3 which equals 7.
Now I know I need t/-2 to equal 7.
Next, I did 7×2 which equals 14.
When you divide 2 negative numbers you get a positive number.
So -14 ÷ -2 = 7
So t = -14
Answer:
143.26 sec
Step-by-step explanation:
Density = 4.3 g/l
Volume flow rate = 0.25 l/s
Mass flow rate = density x volume flow rate
= 4.3 x 0.25 = 1.075 g/s
This means 1.075 grams of the gas is released in 1 sec, therefore,
Time taken for leakage of 154 g of gas is
t = 154/1.075 = 143.26 sec
It’s simple, do: 8+8+10+10, just add them you will get 36. The explanation is: Perimeter is add up all the sides, since it is a rectangle it has congruent sides, so they have the same length
3a + a - 15 = 225 . your substituting b(a-15) into the first equation. <span />
