Answer:
23
/12
1.916
Step-by-step explanation:
Given:
m = -8 degrees/hour, the rate of change of temperature
Let x = hours
Let y = temperature, °F
Then y = -8x + b
where b = constant
When x = 0, then y = b.
Therefore b = initial temperature
If the temperature drops by at least 36 °F in the next x hours, then
b - y(6) ≥ 36
b - (-8x + b) ≥ 36
8x ≥ 36
x ≥ 4.5 hours
Answer: At least 4.5 hours
You got the dot on the right spot, the coordinates are (1.5,2.5) because you reflected across the x axis so the y coordinate changed. The distance between them are 5, because you move half of a unit two times which equals 1 whole unit and 4 whole units. 4+1=5
Answer:
40.5 square inches
Step-by-step explanation:
Rectangle consists of two identical squares.
So, if the sides of square = x,
Then, Width of rectangle = x &
Length of rectangle = x +x = 2x
Perimeter of rectangle = 27 inches
2*(length + width) = 27
2*( 2x + x) = 27 {Combine like terms]
2* 3x = 27
6x= 27 {Divide both sides by 6}
x = 27/6
x = 4.5
Width = x = 4.5 inches
Length = 2x = 2*4.5 = 9 inches
Area of rectangle = length *width
= 4.5 *9
= 40.5 square inches
Answer:
P(Red)= 8/24=1/3
P(Green)= 4/24=1/6
P(red or white) = 8/24+5/24= 13/24
P(not white nor green)= 24/24-(5/24+4/24)= 15/25
P(all colors except yellow)= 24/24- 7/24= 17/24
P(black)= impossible
