Answer:
The answer is d = C/pi.
Step-by-step explanation:
To solve this equation for the variable d, we must isolate it on the right side of the equation. It is currently being multiplied by pi, so to reverse this action, we should divide both sides of the equation by pi.
c = (pi) * d
c/pi = pi/pi * d
c/pi = d
d = c/pi
Therefore, the answer is d = C/pi.
Hope this helps!

Ashley and her brother combined read a total of 33 books over the summer. Ashley read three more than four time as many books as her brother. How many books did each person read?
Answer:
Ashley read 27 books and her brother read 6 books
Step-by-step explanation:
Let the number of books Ashley read be x
Let the number of books her brother read be y;
If Ashley and her brother combined read a total of 33 books over the summer., then;
x + y = 33...... 1
If Ashley read three more than four time as many books as her brother, then;
x = 4y + 3 .... 2
Substitute equation 2 into 1:
From 1:
x + y = 33
4y+3+y = 33
5y + 3 = 33
5y = 33-3
5y = 30
y = 30/5
y = 6
Get x;
Since x+y = 33
x + 6 = 33
x = 33-6
x = 27
Hence Ashley read 27 books and her brother read 6 books

By definition, the slope or gradient of a line describes its steepness, incline, or grade.
Where
m — slope
θ — angle of incline

ΔX
= 296.56505117708°
ΔX = 6 – 0 = 6
ΔY = -4 – 8 = -12
Distance (d) = √ΔX2 + ΔY2 = √180 = 13.416407864999
Equation of the line:
y = -2x + 8
When x=0, y = 8
When y=0, x = 4

A farm raises cows and chickens. The farmer has a total of 46 animals. One day he counts the legs of all his animals and realizes he has a total of 156 legs. How many cows does the farmer have?
Thanks in advance, I really appreciate it :)
Answer:
Step-by-step explanation:
lets note a= chickens
b=cows
a+b=46
also = chickens has 2 legs, cow=4 legs
2a+4b=156..........we divide this equation by 2 so we can work with smaller numbers
a+2b=78 or we cam write a=78-2b
lets replace in the first equation a+b=46
78-2b+b=46
-b=46-78
-b=-32 multiply by -1
b=32
so we have 32 cows with 128 legs
a+32=46
a=14 chickens with 28 legs

Answer:
Slope = -2
Step-by-step explanation:
Since, slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Rise = -(y-intercept)
Run = (x-intercept)
From the graph attached,
y - intercept = -(4) = -4
x - intercept = 2
Therefore, slope the line given in the graph attached will be,
Slope = [tex]\frac{-4}{2}[/tex] = -2
Slope = -2
Write an equivalent ratio that is triple 7 to 11
