Answer:
y = 541
Step-by-step explanation:
The mean is calculated as
mean = 
Mean of set A = 
= 
= 266
ratio between means = 7 : 12, then
mean of set B = 
× 266 = 456 , thus
= 456 ( multiply both sides by 5 )
1739 + y = 2280 ( subtract 1739 from both sides )
y = 541
The amount of shirts and pants the clothier makes is an illustration of a linear equation
The equation that represents the number of shirts, and the number of pants is 4s + 6p = 40
<h3>How to determine the equation</h3>
The rates are given as:
Shirts = 4 hours
Pants = 6 hours
In time t, the shirts and pants made is represented with:
t = 4s + 6p
Given that the time is 40 hours, the equation becomes
4s + 6p = 40
Hence, the equation that represents the number of shirts, and the number of pants is 4s + 6p = 40

Answer:
0.17
Step-by-step explanation:
The function can be rewritten as ...
B(t) = 9300·((1/2)^6)^t = 9300·(1/2)^(6t)
In order to multiply the number of bacteria by 1/2, the value of the exponent 6t must be equal to 1:
6t = 1
t = 1/6 ≈ 0.166667 ≈ 0.17
The culture loses half its size every 0.17 seconds.
Answer:
Step-by-step explanation:
1.)
3x=3
x=1
2+y=0
y=-2
solution: (1,-2)
2.)
6y = -36
y = -6
-4x+12 = -12
-4x=-24
x = 6
solution: (6,-6)
Metallic ribbon: 16$ for 4ft
Dividing both sides by four, we get:
1 feet -- 4 dollars
White ribbon 3$ for 1 feet
1 feet -- 3 dollars
<h2><u><em>
Therefore, the Metallic ribbon costs more per feet.</em></u></h2>
