(4logs/2hours) = (x logs/8 hours)
(4/2) = x/8)
Cross multiplication gets you:
(4)(8) = (2)x
32 = 2x
x = 16
16 logs
Answer: d = 1/3
Step-by-step explanation: 48y = 48/4 = 12. So, 2d(18) is equal to 12. 12/18 is 2/3 so 2d has to equal 2/3. That means d = 1/3.
141.3 <em>is </em>the nearest tenth. 0.3 is in the tenths place.
Answer:
Option A is correct, i.e. x = -3, x = 7.
Step-by-step explanation:
Given the equation is x² -4x -21 = 0.
We can compare it with general quadratic equation i.e. ax² +bx +c =0.
then a = 1, b = -4, c = -21.
We can use Quadratic formula as follows:-
x = ( -b ± √(b²-4ac) )/2a
x = ( +4 ± √(16-4*1*-21) )/2*1
x = ( +4 ± √(16+84) )/2
x = ( +4 ± √(100) )/2
x = ( +4 ± 10 )/2
x = (4+10)/2 or x = (4-10)/2
x = 14/2 or x = -6/2
x = 7 or x = -3
Hence, option A is correct, i.e. x = -3, x = 7.
Answer: The correct option is A.
Explanation:
The slope intercept form is,
Where m is slope.
The point slope form is,
Where m is slope.
On Comparing the first equation with slope intercept form, we get m = -8.
On Comparing the second equation with point slope form, we get m = -2.
On Comparing the third equation with slope intercept form, we get m = 7.
On Comparing the Fourth equation with point slope form, we get m = 6.
The steepest line have greatest absolute slope value.
Since the equation 1 has greatest absolute slope value,i.e., 8 therefore option A is correct.
