Answer: 3
Step-by-step explanation:
3x2 = 6
6+8=14
The probability that a vowel will land face up on the cube would be 1/2. This is because there are six total letters; three vowels and three consonants, so there is a 3/6 chance of it being a vowel and you simplify it down to 1/2. I hope this helped :)
Answer:
a = 19
Step-by-step explanation:
Given the equation of:
First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:
Subtract both sides by 5 to isolate the variable:
Therefore, the value of a is 19.
Easy way, visual
50---68---80%
Difference 18 12
Invert order to give ratio of 50% and 80%
Ratio 12 18 = 2:3
So by simple proportion:
volume of 50% needed = 100*2/(2+3)=40 mL
volume of 80% needed = 100*3/(2+3)=60 mL
Algebra way
Let x=volume of 50% needed.
Then
0.50*x+0.80*(100-x) = 0.68(100)
Expand and solve for x
0.5x+80-0.8x = 68
0.8x-0.5x = 80-68
0.3x = 12
x=12/0.3 = 40 mL (volume of 50%)
100-x=100-40=60 mL (volume of 80%)
Answer:
Length of CD is 10.7 cm
Step-by-step explanation:
we are given to find length of CD
Calculation of CD:
