Answer:
19.9 days
Step-by-step explanation:
The amount remaining after d days is ...
a = (1/2)^(d/7)
We want to find d when a = 0.14
log(a) = (d/7)log(1/2)
d = 7·log(0.14)/log(1/2) ≈ 19.855 ≈ 19.9
The farmers need to wait about 19.9 days for it to be safe.
The Distributive property states that
a(b+c)=ab+ac
Now, let's simplify:
6(3a-4)
18a-24
Answer:
first you multiply 6 and 3a which equals 18a. Then you multiply 6 and 4 which equals 24. So in the end it should look like: 18a-24
What is the common ratio?
Answer:
Cai's Would Be Bluer
Step-by-step explanation:
Since 2/5 is 40% and 5/11 is 45% Cai's would be bluer!
Cai's paint will be bluer because she used a higher percentage of blue paint (45.45%) in her mix compared to Casho who used 40% blue paint.
In order to determine whose paint mix will be bluer, we must compare the ratio of blue to red paint in each student's mix. Cai mixes 5 cups of blue and 6 cups of red paint. Casho mixes 2 cups of blue and 3 cups of red paint. We find the percentage of blue paint by dividing the amount of blue paint by the total amount of paint and then multiplying by 100. For Cai, it would be (5 / (5 + 6)) * 100 = 45.45% blue. For Casho, it would be (2 / (2 + 3)) * 100 = 40% blue. Thus, Cai's purple paint will be bluer because it has a higher percentage of blue paint.

a. Select a scatter diagram with the line speed as the independent variable.b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?
Answer:
Here's what I get
Step-by-step explanation:
(a) Scatter diagram
The scatter diagram is the figure below.
(b) Interpretation
The scatter diagram shows there is a linear relationship between the variables.
The defective number decreases as the line speed increases.
The inspectors miss more faulty parts when the line speed increases, so they report fewer of them.
Step-by-step explanation:
1) angle 2 and 4
2)angle 2 and 3
3)angle 1 and 4

similar to the graph of x > a? How is it different?
Answer:
• If the equations of a and b are polynomials,it'll be a curve between a and b [ b<x<a]
• If the equations of a and b are linear,it'll be a line between a and b
