150 minutes / day for a week
= (150 minutes / day) * (7 days / week)
= 150 * 7 minutes / week
= 1050 minutes / week
(1050 minutes / week) * (1 hour / 60 minutes)
= (1050 / 60) hours / week
= (105 / 6) hours / week
= 17.5 hours / week
You could also convert to hours first. 150 minutes = 2.5 hours * 7 days = 17.5 hours per week.
Answer:
C
Step-by-step explanation:
Perpendicular lines have slopes which are the negative reciprocal of each other. To find the slope, convert 3x-5y=8 into y=mx+b form.
3x-5y=8
-5y = -3x +8
y = 3/5 x - 8/5
The slope is 3/5 so its perpendicular slope is -5/3. Write the equation of this line through the point (3,7) using point slope form. Then simplify into y=mx+b form.

Answer:
90 of the students are girls.
Step-by-step explanation:
Boys : Girls
B : G
4 : 3
120 : ?
(120 ÷ 4 = 30) so 4 × 30 = 120
(Do this to the other side) 3 × 30 = 90
B : G
120 : 90 [90 girls out of 210 total students]
Hope this helps. :)
Answer:
Divide $26.25 by 3 to find out the cost of the unit price. It is $8.75.
An x-intercept is the poin where a graph that intercepts the x-axis. The graph can be a linear function (a line), a quadratic function (a parabola), Higher degree functions and so on.
