Answer:
20 ways
Step-by-step explanation:
6C3 = 6!/(3! * (6-3)!)
= (6*5*4*3*2*1)/(3*2*1*(3)!)
= (6*5*4) / (3 * 2 * 1)
= (6*5*4)/6
= 5 *4
= 20 ways
The number of ways to pick 3 items not to take out of a total of 6 is 20.
To find the number of ways to pick 3 items not to take out of a total of 6, we can use the combination formula. The formula for combinations is given by C(n, r) = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to be chosen. In this case, n = 6 and r = 3. Plugging in these values, we get:
C(6, 3) = 6! / (3!(6-3)!) = 6! / (3!3!) = (6 * 5 * 4) / (3 * 2 * 1) = 20.
So, there are 20 different ways to pick 3 items not to take out of a total of 6.

Answer:
7 4/18
Step-by-step explanation:
(8 2/3)/(1 1/5) = (26/3)/(6/5) = (26/3)(5/6) = 130/18 = 7 4/18
7 is the integer that goes in the blank
Answer:
n = -10
Step-by-step explanation:
solving a one step equation with a missing variable
step 1: subtract 3 from both sides of the equation then simplify
ex: n + 3 - 3 = -7 - 3 (n = -10)
step 2: take your answer of n which is -10 and add plug it in into your original equation n + 3 = -7 and solve to check your answer
ex: n + 3 = -7 (-10 + 3 = -7)
add
-10 + 3 = -7
-7 = -7 (if both sides of the equation are the same numbers like -7 = -7 then your answer is true making n = -10 your answer) i would love to get brain if this is correct and helps <(^w^)>

Answer:
Length = 49 feet
Step-by-step explanation:
Since 35/5 is equal to 7, that means for every inch on the drawing it represents 7 feet. So you could multiply 7(7) to get the actual length.
Answer:
$3300 at 4%
$11700 at 7%
Step-by-step explanation:
Total investment = $15000
Total simple interest on investment = $951
Investment A:
Rate = 4% =0.04
Investment B:
Rate = 7% =0.07
Simple interest (S. I) = principal * rate * time
(S. I on investment A + S. I on investment B)
Let principal amount in investment A = A
principal amount in investment B = B
(A * 0.04 * 1) + (B * 0.07 * 1) = $951
0.04A + 0.07B = $951 - - - - (1)
A + B = $15000 - - - - (2)
from (2)
A = 15000 - B
Substitute A = 15000 - B into (1)
0.04(15000 - B) + 0.07B = 951
600 - 0.04B + 0.07B = 951
600 + 0.03B = 951
0.03B = 951 - 600
0.03B = 351
B = 351 / 0.03
B = $11700
From (2)
A + B = $15000
A + $11700 = $15000
A = $(15000 - 11700)
A = $3300
