Answer:
When using the given information, the diameter of the circle is going to be 28 mL.
Step-by-step explanation:
First, we need to know the formula for finding the area of a circle.
Now, we need to rearrange the formula so we can find the radius.
Next, we plug in the given area into the equation.
Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.
So, the diameter of the circle is 28 mL
Answer:
Let's say Raj's height is 60 inches
60-3 = H
H= Howard's height
60 = Raj's height
Or it could be with two variables
R-3 = H
R = Raj's height
4 products are being purchased.
Step-by-step explanation:
Given,
Time taken to select each product = 5 seconds
Time taken to complete check out process = 60 seconds
Total time taken for a transaction = 80 seconds
Let,
x be the number of products purchased.
Time taken for each product*Number of product + Time for check out process = total process
Dividing both sides by 5
4 products are being purchased.

Answer:
15x + 40 = 115
We set the equation to 115 because the total cost is $115.
We add the "+ 40" because of the $40 to rent the trailer for the day.
The 15x is because it represents the miles per hour (x) times the number of hours.
The number of hours times the charge per mile, plus the $40 to rent it, will equal $115.
Hope this helps!!
Answer:
1) gradient (00) (-2 4) = y2-y1 / 2-1 = 4/-2 = -2 m = -2/1 means = m = -2 (negative slope) 2) gradient y2-y1 / x2-x1 = 3-0 / 2-0 = 3/2 = (1 1/2)/1 m = 1 1/2 (positive slope) we use the formula y-values divided by the change in the x-values. The equation of the gradient each goes like this 1) y = -2x as y is at origin nothing else to add The equation of the gradient each goes like this 2) y = 1 1/2x The equation of the point formula 1) we take the y -y1 = m (x +x 1) = y-0 = -2x (x +0) (as m = -2) y = -2(x +0) and The equation of the point formula 2) y - 0 = m ( x +x1) y - 0 = 1 1/2( x +0) = y = 1 1/2( x +0)
