She was 5 hours on her computer

Number of hours worked = 7\frac{1}{2}

This is an improper fraction so first we convert it

7\frac{1}{2} = > \frac{15}{2}

Time spent on her computer = \frac{2}{3} of working hours

∴ time spent on computer = (15/2)*(2/3)

= 5 hours

Answer:

5 hrs

Step-by-step explanation:

7 1/2 hours equates to 450 minutes total

2/3 of 450 = 300 total minutes

turning the minutes back into hours, 300 / 60 = <u>5</u>

A survey was done to determine the effect of students changing answers while taking a​ multiple-choice test on which there is on
Umnica [9.8K]

Answer:

6% of the changes were from incorrect to​ incorrect

Step-by-step explanation:

The sum of the percentages must be 100%.

We have these following percentages

65​% of the changes were from incorrect answers to correct

29​% were from correct to incorrect

P% were from incorrect to incorrect

So

65 + 29 + P = 100

P = 100 - 94

P = 6

6% of the changes were from incorrect to​ incorrect

Please help! what is the polar equation r = -5 theta in parametric form?<br><br> thank you!
Rudiy27

Use these equations when converting polar equations to parametric equations:

x=r\cos\theta

y=r\sin\theta

We know that r=5\theta, so substitute that into both equations for x and y.

x=5\theta\cos\theta

y=5\theta\sin\theta

Now, replace \theta with any variable that you want to represent the parametric equations in. I'll use the standard variable, t

x=5t\cos t

y=5t\sin t

Thus, r=5\theta represented in parametric form is:

(x,y)=(5t\cos t, 5t \sin t)

Let me know if you need any clarifications, thanks!
