<h3>So first of all you have  Rachel who has read the book for 16 hours. Then it took Ross 790 minutes to read the book Minutes * 60 = 1 Hours so it took him/her  13.166666666667 hours So about 13 hours. Now Monica read her book in  60500 seconds in hours that is 16.805555555556 So about 16 hours as well. So I would say that finally the person who finished there book first was  Ross with 13 hours. Hopefully that helps you ❤</h3>

Kristen can run at 9kmh-1 and walk at 3kmh-1. She completed a 42km marathon in 6 hours. What distance did Kristen run during the
Hatshy [7]
Kristen completed 42 km. We will imagine that she ran all 6 hours. => 9 * 6 =54 km which is more than she actually completed. So we will find a 9 Multiple less than 42 km and that will be 36 km. (9 * 4 = 36 km completed by running) and the rest until 42 were completed by walking (3 * 2 = 6; 6 + 36 =42).

Please Help for both 6 and 7. I’m confused on both. Please show Explanation. Will Select Brainliest.
krek1111 [17]

answer: 32, 72

question 6

angle PQR and 148 are supplementary angles, so they add up to 180

PQR + 148 = 180

PQR = 180 - 148 = 32

question 7

in triangle RTS, all three angles must add up to 180

angle R = angle PQR = 32

angle S = 180 - 104 = 76 (because of supplementary angles)

angle T = angle RTS (we need to find this)

32 + 76 + angle RTS = 180

angle RTS = 72

What is the quadratic equation to this question
-BARSIC- [3]

Answer:

f(x) = 4x − 12

Step-by-step explanation:

It's not quadratic.  It's linear.  Each time x increases by 1, f(x) increases by 4.  So the slope is 4.  The y-intercept (when x=0) is -12.  The equation of the line is therefore:

f(x) = 4x − 12
