<em><u>Question:</u></em>
A machine made 2 2/6 pencils in 3 3/4 minutes. How many pencils would the machine have made after 9 minutes?
<em><u>Answer:</u></em>
pencils is made after 9 minutes
<em><u>Solution:</u></em>
Given that,
A machine made 2 2/6 pencils in 3 3/4 minutes
Which means,
Let "x" be the number of pencils made in 9 minutes
Therefore,
This forms a proportion and we can solve by cross multiplying
Thus, pencils is made after 9 minutes
This is a Linear equation, which means it gives a straight line when plotted on a graph. Please make Brainliest! ☺
y = -3(x<span> - 2)^2 + 1 </span>x<span>-coordinate of vertex: </span>x<span> = -b/(2a) = -12/-6 = 2 y-coordintae of vertex: y(2) = -12 + 24 - 11 = 1 </span>Vertex form: y = -3(x<span> - 2)^2 + 1 Check. Develop y to get back to standard form: y = -3(</span>x^2 - 4x + 4) + 1 = -3x<span>^2 + </span>12x<span> - </span>11<span>. </span>
Answer:
5 minutes
Step-by-step explanation:
We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.
Hey there! :D
Divide 15 by the numerator so we can find 1/7.
15/5= 3
3*7= 21
The number is 21.
I hope this helps!
