Answer:
11.17 tonnes was in the fourth and final load.
Step-by-step explanation:
11.25 + 12.76 + 12.82 = 36.83 > total of the first 3 loads.
x = 4th load.
36.83 + x = 48
x = 48 - 36.83
x = 11.17

2. Ratio is the relationship that compares one value to another in a fraction-like manner.
3. Equation is a statement that compares who values with an equality sign.
4. The perimeter is the distance around the object while the area is the amount of space inside the area.
Answer:
x = 2
y = -3
z = 4
( 2 , -3, 4 )
Step-by-step explanation:
x + y + z = 3 ---- i
x – y =5 ---- ii
y - z = -7 ---- iii
ii + iii
x - z = -2 ---- iv
i + ii
2x + z = 8 --- v
iv + v
3x = 6
x = 2
x=2 substitute for v
z = 4
x =2 substitute for ii
y = -3
Answer:
Step-by-step explanation:
Let f(x) = x^7 - 4e^x
.
Then f '(x) = 7x^6 - 4e^x, and
f "(x) = 42x^5 - 4e^x, and so:
f '(-1) = 7(-1)^6 - 4e^(-1) = 7 + 4/e
and
f "(x) = 42(-1)^5 - 4e^(-1) = -42 + 4/e
