The median score on the test is 79
Answer:
The correct answer is option B. 4√3/3
Step-by-step explanation:
<u>Points to remember</u>
If a right angled triangle with with angles 30°, 60° and 90° then the sides are in the ratio 1 :√3 : 2
<u>To find the value of y</u>
From the figure we can see two right angled triangle.
From the figure we get height 'h' of large triangle is written by,
h : base : 8 = 1 : √3 : 2
Therefore h = 8/2 = 4
Also we can write,
y : h : hypotenuse of small triangle = 1 : √3 : 2
y : 4 : hypotenuse = 1 : √3 : 2
Therefore y = 4/√3 = 4√3/3
The correct answer is option B. 4√3/3
Don't know try something else it will probably help
Answer:
y=7
Step-by-step explanation:
Assuming that the equation is 14-2y=0
We need to isolate 'y' variable to obtain its value, to do that, lets start by subtracting -14 to both sides of equality sign,
14-2y=0 is now this: 14-14-2y=0-14, which is equals to -2y=-14
Now, lets continue by dividing by -2 both sides of equality sign.
We have this
-2y/-2=-14/-2
y=7
Thus, we've obtained the value for 'y' variable
Answer:
1.33 km
Step-by-step explanation:
(3 min) (2/3 min) = 2 min
(2 km) (2/3 km) = 1.33 km
