Answer:
b = 8√3 and c = 16
Step-by-step explanation:
<u>Points to remember</u>
If the angles of a right angled triangle with angles are 30°, 60, and 90 the their sides are in the ratio 1 : √3 : 2
<u>To find the unknown side lengths</u>
From the given figure we can see a right angled triangle
Angles are 30°, 60° and 90°
sides are in the ratio 1 : √3 : 2
1 : √3 : 2 = 8 : b : c
b = 8√3 and c = 8 * 2 = 16
Therefore b = 8√3 and c = 16
Yes, 16.3 is y maybe but or else I need to use a protractor I believe
Step-by-step explanation:
Step 1:
A . 5 with an exponent of 3 times 5 with an exponent of -4
= 
= 
= 
= 1/5
B . (1/4) with an exponent of 3 times (1/4) with an exponent of 2
= 
C. Same as above
D. 
Step 2 :
All the above expressions have a value between 1 and 2
Answer:
x÷14
Step-by-step explanation:
A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?
The positive whole-number factors of 30 are:
1, 2, 3, 5, 6, 10, 15 and 30.
So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that
P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors
=38=3×.125=.375
