Answer:
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to 10 a.m. was -10 1/2 degrees
Step-by-step explanation:
Initially, the temperature was 3 1/2 degrees Fahrenheit at 3 a.m. From 3 a.m., the temperature change at 1 1/2 degrees per hour for the next 7 hours. This means that the temperature change in the next 7 hours is:
Temperature change = 7(-1 1/2) = -10 1/2
In the next 7 hours from 3 a.m. to 10 a.m., that is at 10 a.m. (3 a.m. + 7 hours), the temperature change was -10 1/2 degrees Fahrenheit.
Hence:
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to 10 a.m. was -10 1/2 degrees

5. Consider the image below of a pasture at McDonald's Farm.
750 ft
45°
Part A: If McDonald wants to fence in the square pasture and barbed-wire
fencing costs $1.15 per foot, then determine the cost to fence in
the pasture.
Part B: If McDonald wants to cover the square pasture in fertilizer, then he
needs to determine the area of the pasture. What is the area of
the pasture to the nearest hundredth?
Answer:
Step-by-step explanation:
The area of the square pasture is given by the leg length of the right
triangle which is the same as the side length of the square.
Correct responses:
Part A: $2,439.5Part B: 281, 250 ft.²Method by which the above responses are obtainedPart A
The given triangular side is a right triangle.
Length of the hypotenuse and an acute angle of the right triangle are;
750 ft. and 45°
Therefore;
Leg length of the right triangle = Side length of the square
Leg length of the right triangle = 750 ft. × sin(45°) = 375·√2 ft.
Side length of the square pasture, s = 375·√2 ft.
Perimeter of the fence = 4 × 375·√2 ft. = 1500·√2 ft.
Cost per foot for fencing = $1.15
The cost to fence the square pasture = $1.15/ft. × 1,500·√2 ft. ≈ $2,439.5Part B:
The area, A, of the square pasture is given by A = s²
Which gives;
A = (375·√2)² = 281,250
The area of the square pasture is A = 281,250 ft.²

Answer: 3(x+5) ✅
Step-by-step explanation:
Hii, do you need to factor the expression 3x+15? No problem! (:
Note that 3x and 15 have a "3" in common.
To factor it out, we can divide 3x and 15 by 3 first.
x+5
Put parentheses around x+5
(x+5)
Now put the 3 that we just factored out outside these parentheses
