Answer:
sqrt( 146)
Step-by-step explanation:
To find the distance, we use the following formula
d = sqrt( ( x2-x1) ^2 + ( y2-y1) ^2)
sqrt( ( -9-2) ^2 + ( 0-5) ^2)
sqrt( ( -11) ^2 + ( -5) ^2)
sqrt( 121+25)
sqrt( 146)
Answer:
D 4/121
C 14/55
Step-by-step explanation:
The total number of tiles in mathematics is 11
P(a) = number of a's/ total = 2/11
We replace the tile
so there are 11 tiles and the are mathematics
P(a) = number of a's/ total = 2/11
P(a, replace then a) = 2/11 *2/11 = 4/121
P(vowel) = vowel/total = 4/11
We keep the vowel so there are only 10 tiles
3 vowels and 7 consonants
P( consonants) = consonant/total = 7/10
P(vowel, no replace, consonant) = 4/11*7/10 = 14/55
Answer:
tell me if u get this
Step-by-step explanation:
15% = 6 problems
30% = 12 problems
45% = 24 problems
60%= 36 problems
75%= 48 problems
95% = 60 problems
15%/3% =5% 6/3 =2 problems
100%= 62 problems
There were 62 questions on the test,
We can write this in math as x+y+z=104, x=y-6, and z=3y
Because we already know what x and z are in terms of y, we can substitute our values for x and z into the first equation. This now looks like (y-6) + y + (3y) = 104. Now we can simplify our equation to find our value for y.
y-6 + y + 3y = 104 simplifies to 5y - 6 = 104, then 5y=110, and finally y=22.
Now that we know our value for y we can find our values for x and z by substituting our value for y into the other two equations.
The second equation x = y-6 can be simplified as x = 22 - 6 and further simplified as x = 16.
The third equation z = 3y can be written as z = 3(22) or z = 66.
Our three numbers are 16, 22, and 66. Hope this helps you!
