trevon spent 8 hours and 15 minutes at an amusement park yesterday he spent 75% of the time at the park about how much time did he spend on rides

Answers

convert 8 hours and 15 minutes into minutes- 8 x 60=480 480+15=495
100%-75%=25%
25%=0.25
0.25 x 495 = 123.75 minutes or 2 hour and 3.75 minutes

Hope this helps!!

so 8 hours+15mins at park
park=75%
rides=100%-park=100-75=25%
HACK ALERT
25% is 1/4 so multiply 8 hours and 15 mins by 1/4 so
8 h and 15 mins times 1/4=8h times 1/4+15mins times 1/4=2h+3.75min=

2 hours and 3.75 mins spent on rides

What value for c will make the expression a perfect square trinomial? x2 – 7x + c

Answers

Answer: 12.25

Step-by-step explanation:

A perfect square trinomial is written as $ax^2+2abx+b^2$ , where

first term $ax$ = square of first term of binomial

second term=2abx=twice the product of both terms of binomial.

and third term 'c'=square of last term of binomial

In the given polynomial , $x^2+7x+c$ , a=1

and 2ab = 7

When we put value of a =1, we get

$2(1)b=7\n\Rightarrow\ b=(7)/(2)$

Hence, in place of the question mark makes the given polynomial a perfect square trinomial = $b^2=((7)/(2)^2=12.25$

I assume the first part of that equation is x^2. -7/2= 3.5 ; 3.5^2=12.25 sooo it should end up as x^2-7x + 12.25. but I might be wrong.
