Answer:
T' is at (-1,-8)
Step-by-step explanation:
When we translate down 4 units, we will subtract 4 from the y coordinate
T is at (-1,-4)
We need to subtract 4 from the y coordinate
T' is at (-1,-4-4)
T' is at (-1,-8)
4*x+7=12
4*x=5
x=5/4
The number is 5/4
The amount of time spent reading email to the amount of time spent watching television is 1/12
Step-by-step explanation:
Given
Time to read email = 15 minutes
Time on television = 3 hours = 3*60 minutes = 180 minutes
Ration is the fraction between two things. In this case, the ration is from the amount of time spent reading email to the amount of time spent watching television
So,
Required ratio will be: 15/180
Simplifying => 1/12
So,
The amount of time spent reading email to the amount of time spent watching television is 1/12

Answer:
x=12.5
Step-by-step explanation:
The given triangle is a right angle triangle.
We cannot use the Pythagoras theorem as the lengths of all sides are not known. We will use triangular ratios here to solve the given problem.
As it is clear from the diagram that x is the hypotenuse of the triangle and 11 is the length of the base. We will use a ratio in which base and hypotenuse are used.
So,
cos θ= base/hypotenuse
cos 28=11/x
x=11/cos28
x=11/0.8829
x=12.45
Rounding off to nearest 10
x=12.5
