Answer:
11.4 mixture:26 and 2/3
7.8 mixture: 53 and 1/3
Step-by-step explanation: Sorry if this is hard to underestand. This is my first answer. This is a RSM question that has been checked.
11.4+7.8=9
x+80-x=80
Multiply
11.4x+624-7.8x=720
3.6x=96
1.2=32
0.6x=16
6x=160
x=26 2/3
80-26 2/3= 53 1.3
Answer:
The correct answer is - C. 11.45 ounces to 11.75 ounces.
Step-by-step explanation:
According to the empirical rule of the distribution for 68% falls under the normal curve falls within 1 standard deviation of the mean.
That is:
μ±δ
From the given information, the mean is
μ = 11.60
and the standard deviation is
δ = 0.15
We substitute the given parameters to obtain;
11.60±0.15
11.75 and 11.45
This means the lower limit is
11.45
and the upper limit is
11.75
Question:
Solution:
The solution to a system of linear equations is where the graphs of each linear equation intersect. In this case, we can see that the lines intersect at the point:
(-3,2)
thus, the correct answer is (-3,2).
Answer:
9th Triangle
Step-by-step explanation:
Given the area of four triangles:
If the Scale factor is 1.5.
This is a geometric sequence and the common ratio is 1.5 X 1.5.
Therefore, the area of any n triangle can be determined using the function:
We want to determine which triangle has an area greater than .
When A(n)=15000
Therefore, the 9th triangle has an area greater than .
Simplest form would be 3x+18
3(4x+6)-9x
12x+18-9x
-9x
3x+18
