I got this by putting the numbers in their place
Answer:
84
Step-by-step explanation:
because the top and bottom lines are parallel, we can conclude that the 2 triangles (top and bottom) are similar triangles. This means the sides lengths of smaller triangle is proportional to the respective sides on the larger triangle. With this, we can form the following equation:
x/48 = 21/12 (multiply both sides by 48)
x = (21/12)· 48
x = 21 ·4
x = 84
Answer:
Exactly one solution
Step-by-step explanation:
Because they two lines dont have the same slope, they must have only one solution.
Answer: A. 5,000 meters
Step-by-step explanation:
Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:
= 30,000 / 10
= 3,000 meters.
Option c is smaller than B and so is incorrect.
A meter is 100 centimeters. Option b in meters is;
= 6,000 / 100
= 60 meters
This is less than option A so is incorrect.
A kilometer is 1,000 meters so option A in meters is:
= 5,000 / 1,000
= 5 kilometers
This is higher than option d so option A is correct.
I'm going to assume that the ' 7.51 ' is the angle expressed in radians.
So this is just like any other unit conversion exercise.
You know that 180 degrees = pi radians.
Divide each side by pi radians, and you have
180 degrees / pi radians = 1 .
Great ! Now take the angle you have ... 7.51 radians ...
and multiply it by ' 1 '.
(7.51 radians) x (180 degrees / pi radians) =
<em> </em> (7.51 x 180 / pi) degrees =<em> 430.29 degrees</em>
As you ( I ) worked through this problem, a very useful number
fell out . . . It's 180/pi = 57.296 , or just <em>57.3</em> is close enough.
Here's how you can use that number:
-- 1 radian = <u>57.3</u> degrees
-- 1 degree = 1/57.3 of a radian
-- Got some radians ? Multiply by <u>57.3</u> to get degrees.
-- Got some degrees ? Divide by <u>57.3</u> to get radians.
