First find the distance by multiplying 55mi/hr × 1.75 hrs= 96.25mi
Next find the time while traveling at 70mph using this distance. 70 miles/hr = 1hr/70 miles, so multiply 1hr/70mi x 96.25 mi= 1.38 hours
Answer:
B.
Step-by-step explanation:
Answer:
<em>- 1.568</em>
Step-by-step explanation:
Let's assume that the base of the given logarithm is 10.
log m = 0.345 ⇒ 
= m
log n = 1.223 ⇒ 
= n
mn = × = 
= 
log = - 1.568 × log 10 = <em>- 1.568</em>
Answer:
<em>Consistent independent</em>
<em>Consistent dependent</em>
<em>Inconsistent</em>
Step-by-step explanation:
<u>Consistent and Inconsistent Linear Systems</u>
A system of equations is consistent if it has at least one solution. If the solution is unique, then the system is consistent independent, otherwise is consistent dependent, i.e., it has an infinite number of solutions.
When there is no solution for the system, the lines of each equation are parallel but not coincident. A consistent dependent has two non-parallel lines, and a consistent independent system has only one line, i.e. the same line represents both equations.
Two lines are parallel if they have the same slope. To find the slopes, we represent the equations in slope-intercept form:
y = mx + b
Where m is the slope and b is the y-intercept.
Consider the system:
4x + y = 8
x + 3y = 8
Rearranging both equations:
y = -4x + 8
y = -1/3 x + 8
The slopes of the lines are -4 and -1/3 respectively, since they are different, the system is consistent independent.
Consider the system:
-4x + 6y = -2
2x - 3y = 1
Rearranging both equations:
y = 4/6 x - 2/6 = 2/3 x - 1/3
y = 2/3 x - 1/3
Both equations are exactly the same, thus the system is consistent dependent.
Consider the system:
5x - 2y = 4
5x - 2y = 6
Rearranging both equations:
y = 5/2 x - 2
y = 5/2 x - 3
These lines are parallel but not coincident. Thus this system is inconsistent.
Assuming this Fence enclosment will be in the shape of a rectangle we will use the equation used to find the area of a rectangle, b×h=a
Using this formula we then must pick out factors used to create, in which the perimeter will add up to 60
·1,29,1,29 (29)
·2,28,2,28 (56)
·3,27,3,27 (81)
·4,26,4,26 (104)
·5,25,5,25 (125)
·6,24,6,24 (144)
·7,23,7,23 (161)
·8,22,8,22 (176)
·9,21,9,21 (189)
·10,20,10,20 (200)
·11,19,11,19 (209)
·12,18,12,18 (216)
·13,17,13,17 (221)
·14,16,14,16 (224)
·15,15,15,15 (225)
using this we can learn<span> that the maximum area that can be exclosed by this is 225, because the 2 perimeter lengths that define this rectangle would be 15 and 15.
</span>b(15)×h(15)=225(a)
therefore, your answer is 225 Units
