Answer:
- Grayson had 10 inches of snow in his lawn
- the snow falls at a constant rate of 0.5 inches per hour
- no snow was melting
- the snow has fallen for 3 hours
Let y be the height of the snow in the lawn
Grayson had 10 inches at the beginning (at t=0) so y= 10
3 hours passed so y= 10 + 3*0.5 = 11.5 inches
Grayson had 11.5 inches after three hours
Assuming that the snow continued to fall for an unkhown time t
y = 0.5*t + 10
we had 10 at the beginning so we add 10 (+10)
the snow is growing by 0.5 inches in the single hour so we multiply by 0.5
t is the time and it can 4, 5, 6 ...... hours
Just like a function :
- 0.5 is the slope
- t is the variable
- 10 is the y-intercept
243log(81x)=48
log(81x)=48÷243
log(81x)=16÷81
81x=10^(16÷81)
81x= 81sqaure root pf 10^16
divide by 81
x =.0194557

Answer:
Area of the walkway border is 736 ft²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angles) with two pairs of opposite and parallel sides. All angles in a rectangle are 90 degrees each. Also, opposite sides are equal.
The entire pool area has a length of 60 feet and width of 40 feet. The area of the entire pool area is:
Area of entire pool = length * width = 60 feet * 40 feet = 2400 ft²
The area of entire pool
A walkaway border of 4 ft is made around the pool area. There is a decrease of 4 ft round the sides of the pool area.
Therefore length of pool = length of entire pool area - 4 feet border at left - 4 feet border at right = 60 ft - 4 ft - 4 ft = 52 ft
width of pool = width of entire pool area - 4 feet border at top - 4 feet border at bottom = 40 ft - 4 ft - 4 ft = 32 ft
Therefore the pool is 52 ft × 32 ft
Area of pool = length * width = 52 ft * 32 ft = 1664 ft²
Area of the walkway border = Entire pool area - Area of pool = 2400 ft² - 1664 ft² = 736 ft²
