Answers

Answer:

8:05 pm (If you round to the nearest tenth place)

Step-by-step explanation:

basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.

1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes

1.7 minutes times 150 miles is 2 hours and 55 minuets

2 hours and 55 minutes plus 5:10pm is 8:05 pm

I'm so sorry if I'm wrong!

Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65 b: 6:41 pm

duration of time passed:

5:10 pm - 4:00 pm = 70 mins

distance = 65 miles

you points to use to make an equation:

(0,0) and (70,65) ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )

find the slope of your "future" equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m

now use point-slope form

y - 65 = [tex]\frac{13}{14}[/tex] (x - 70)

y= [tex]\frac{13}{14}[/tex] (x - 70) + 65

and since it wants it in terms of d and t,

d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65

part b:

150 = [tex]\frac{13}{14}[/tex] (t - 70) + 65

85 = [tex]\frac{13}{14}[/tex] (t - 70)

85 = [tex]\frac{13}{14}[/tex] t - 65

150 = [tex]\frac{13}{14}[/tex] t

2100 = 13t

161.54 = t

about 162 minutes

Thennnn:

162/60 = 2 hours and 41 mins

4:00 pm + 2 hours and 41 mins = 6:41 pm

Answer:

Step-by-step explanation:

V= L(W)*H/3

V= 6(6)* 10/3

V= 36*10/3

V=360/3

V=120

(V stands for volume)

(L stands for length)

(W stands for width)

(H stands for height)

what are the values of x and y

Answers

x= 35 because it is a vertical angle from the other 35 y= 72.5 because 360 is a circle and we’ve already found 70 of the pieces. meaning we divide 290 by 4 because there are four blanks and that’s 72.5. something might be a little off with my answer but i’m pretty sure i did it right
