In every circle, there is a special relationship between the circumference and the diameter. Determine the decimal value of the ratio of the circumference to the diameter to the nearest hundredth for each circle. Recall that the fraction bar represents division.
Answer:
Step-by-step explanation:
Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).
Answer:
It's 3.14 for each one.
Explanation: The value of pi is 3.14, and it doesn't change depending on the size of the circle. You're welcome! :)

We want to solve the following system of equations using the substitution method.
Equation 1- 4p+7q=92/5
Equation 2- 12p+35q=72
Solve for q
Ok, so you are given the value of P=q+2
The substitution method tells us that we must insert the value we know, into the second equation, 4P+3q= -27
Doing so will give us 4(q+2)+3q= -27
For right now, lets just focus on the first part, 4(q+2)
We can simplify this by distributing(multiplying) the 4 to whats inside the variables.
This will give us 4q+8
now lets add this back to the rest of the equation >>> 4q+8+3q = -27
We can further simplify by adding like terms >>> 7q+8 = -27
subtract the 8 from both sides >>> 7q = -35
now divide both sides by 7 >>> q = -35/7
Therefor q = -5
EDIT*
now that we know q = -5 we can put q into the equation for P !
we know that p=q+2
so lets put q in now >>> p=(-5)+2
and simplify>>> p = -3
I hope this helps:)

What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (0, negative 2) and (3, 0).
Answer:
slope=2/3
y-intercept -2
y=2/3x-2
Step-by-step explanation: You have to do y-y divided by x-x, so 0 mins-2 which equals 2 and 3-0 which equals 3, and then you get 2/3. For the y-intercept, you have to plug in one of the points into x any y so your equation will be -2=2/3(0)+b and then you have to multiply 2/3 and 0 and you get 0 so your equation is -2=0+b and finally, you have to subtract -2-0 which equals -2 and your y-intercept is b=-2.

2/3, -2

square root 170, 13.5, 64/5, 13 7/8
please help DUE TODAY
Answer: (Decreasing Order) 170, 13 7/8, 13.5, 64/5
Step-by-step explanation:
Sqrt 170 = 13.038
Sqrt 13.5 = 3.674
Sqrt 64/5 = 12.8 = 3.577
Sqrt 13 7/8 = 13.875 = 3.724
The values in decreasing order are- 13.5 > 13 > 64/5 > square root 170 > 7/8
What is decending order?A series arranged that begins with the greatest or largest and ends with the least or smallest is called as descending order.
The given numbers are,
square root 170, 13.5, 64/5, 13 7/8
Before comparing, we need to write all of those numbers in decimal form.
So, converting all the numbers in decimal for,
square root 170 = √70 = 8.336
13.5
64/5 = 12.8
13
7/8 = 0.875
Hence arranging them from highest to lowest,
13.5 > 13 > 12.8 > 8.336 > 0.875
Thus, the decreasing order of original numbers are,
13.5 > 13 > 64/5 > square root 170 > 7/8

Step-by-step explanation:
area = base × height / 2
22.68 = base × 5.6 / 2
Multiply both sides by 2.
45.36 = base × 5.6
Divide both sides by 5.6.
8.1 = base
Answer: base = 8.1 units
