Answer:
2 hours
Step-by-step explanation:
First we need to know the distance Liam travelled using the bike.
If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:
d = 8 * 3 = 24 miles
The total distance is 30 miles, so the remaining is:
30 - 24 = 6 miles
He travelled 6 miles with the speed of 3 mph, so the time walking is:
time = 6 / 3 = 2 hours
Answer:
Step-by-step explanation:
Given :
From the diagram,
m∠GEF is 13 less than 5 times m∠DEG and ∠DEF = 149°,.
To Find :
the value of m∠GEF..
Solution :
As per given data,
m∠GEF = 5m∠DEG - 13° ...(i)
∠DEF = 149° ⇒ m∠GEF + m∠DEG = 149° ..(ii)
Substituting value of m∠GEF in (ii),
We get,
(5m∠DEG - 13°) + m∠DEG = 149°
6m∠DEG - 13° = 149°
6m∠DEG = 149° + 13° = 162°
m∠DEG = ° = 27°
Substituting value of m∠DEG in (i),
We get,
m∠GEF = 5(27°) - 13°
m∠GEF = 135° - 13°= 122°
The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation 9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +-
Answer:
No, it is not
Step-by-step explanation:
Here, we want to check if what we have is a function
For a relation to be a function, the mapping must be one to one or many to one
This mean, for every x there must be one y or for every y, there must can be multiple x
But never is it that there are many y for a single x
Looking at the value 0
on the domain, we can see -2 and 1 as the values
Thus, this is not a function
Step-by-step explanation:
2250mg = 2250/1000 = 2.25g
59.4kilolitres = 59.4 ×1000 = 59400litres
0.000072g = 0.000072x 1000000 = 72micrograms
3.98 x 10^6 in = 3.98 × 10^6 × 25.4 × 10^-6 = 1.01092 × 10^2 km
or
3.98 × 10^6 m = 3.98 × 10^6 × 10^-3 = 3.98 × 10^3
