Answer: t = 11.57s
The time taken for the Boxster to catch the Scion is 11.57s
Step-by-step explanation:
Given;
Speed of the boxster = 26.4m/s
Speed of the Scion = 15.6m/s
Assuming the starting point of 0 for the boxter, the starting point of the Scion would be 125.0m.
Given that;
Distance = speed × time
For the Boxster the distance travelled is;
d = 0 + 26.4t
For the scion the distance travelled is ;
d = 125 + 15.6t
Where t is the time.
Equating the two distance;
26.4t = 125 + 15.6t
26.4t - 15.6t = 125
t = 125/(26.4-15.6)
t = 11.57s
Answer:
Step-by-step explanation:
Multiplying anything by zero equals zero. So if either term equals zero the equation is true.
(x-6)(x+5)=0
So if x=-5 or 6 the above is true.
x=(-5,6)
The first one can be written as a fraction because it is a repeating decimal.
The second one can be written as a fraction because it is a repeating decimal.
The third one can not be written as a fraction since it is nether terminating nor repeating.
The last one can be written as a fraction since it is a terminating decimal.
Answer: See below
Step-by-step explanation:
14) 26/52 of the cards are red, 1/2
15) All of the cards are red or black, 1/1
16) 4/52 of the cards are aces, 1/13
17) 12/52 of the cards are J/Q/K, 3/13
Convert the fractions to whatever unit is needed.
Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
