It will take 1/2 an hour because if 1/2 of a wall is painted with 1/4 of an hour, then we know if you want the other half, you have to add another 1/4 of an hour which is 2/4.
2/4 is equivalent to 1/2 so 1\2 of an hour is how long it will take.

Answer:
D
Step-by-step explanation:
Here, we want to get the equation of the line perpendicular to;
y = -3x + 2
From here, we can compare with the standard form of the equation of a straight line which is;
y = mx + c
From here m = -3
The slope is -3
Now, if two lines are perpendicular, the product of their slopes is -1
Thus;
-3 * m = -1
m = 1/3
So we want to select an equation out of the options that has a slope of 1/3
Let us take a look at the last option
x -3y = 3
3y = x-3
divide through by 3
y = x/3-1
So here the coefficient of x is 1/3 which is the slope of the perpendicular line that we are looking for and is our slope
Answer:
Step-by-step explanation:
The given data table is
Number of seconds : 0 1 2
Height (in feet) : 11 13 13
We need to find quadratic regression equation that fits these data.
The general form of quadratic regression equation is
.... (1)
Using the graphing calculator we get
a = -1 , b = 3 and c=11
Substitute these values in equation (1), to find the quadratic regression equation that fits these data.
Therefore, the quadratic regression equation that fits the data is .
30 pencils multiplied by 1/6 is equal to 30/6. Reduce 30/6 to lowest term by dividing 30 by 6. The quotient of 30 and 6 is 5. Therefore, Jake used 1/6 or 5 pencils of the 30 pencils in a pack.
Answer:
77 cm²
Step-by-step explanation:
We know that
Area of trapezium = ½ (a + b) × h
Area = ½ × (10 + 12) × 7
Area = ½ × 22 × 7
Area = 11 × 7
Area = 77 cm²
