Answer:
0
Step-by-step explanation:
The total number of events is
45+37+52+94+72 = 300
P(purple) = purple/total
= 0/300
=0
Answer:
Let AB be the flagstaff and CD be the vertical tower.
AB=10m=EC
BC=20m=AE
In triangle ABC we have,
tanx=AB/BC
tanx=10/20
1/tanx=20/10
10/tanx=20...........1
In triangle ADE we have
tan(90-x)=DE/AE
cotx=DE/20
1/cotx=20/DE
DE/cotx=20..............2
by eq1 and. eq 2 we get
10/tanx=DE/cotx
10/(AB/BC)=DE/(BC/AB)
10/(10/20)=DE/(20/10)
10×20/10=DE×10/20
DE=40m
Therefore height of vertical tower = DE+EC=40+10=50m
Answer:
(a) (x times x) + (5 times x) + 4
Step-by-step explanation:
Using my answer you first do exponent, so x times x then 5 times x and then 4 times x BUT keep those numbers apart still!
okay now we will take
and add that value to 4 so we now have the numerator‘s value and for the denominator you will take
And multiply 4 times x and add those two answers and finally add the 3 you will have finished the denominator and FINALLY divide the numerator‘s result by the denominato’s result and you now have your answer.
the secret? Order of Operations or PEMDAS
1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
5. BOOM the result will be your answer!
first we must solve 14.5*10 to the -6 power
10 to the -6 power is 0.000001
so, 14.5 times 0.000001 is 0.0000145
Now to turn 0.0000145 into scientific notation, the decimal needs to be moved 5 places to the right, so the exponent base of 10 will be 5 and since the number is less than 1 the sign of the exponent will be negative,
so you get 1.45*10 to the -5th power
your final answer:
<u>0.0000145 = 1.45*10 to the -5th power</u>
