Answer:
325
Step-by-step explanation:
40/100=130/x
Cross multiply to find x
40x=13000
/4 /4
x=325
Answer:
8 minutes
Step-by-step explanation:
time = distance/speed
A decrease of 15 mph from 45 mph means the speed on the second segment is 30 mph. Filling in the given values in the above equation, we have ...
... time = (4 mi)/(30 mi/h) = 4/30 h = 8/60 h × (60 min/h) = 8 min
Answer:
7 hours/week
Step-by-step explanation:
A "unit rate" is found by dividing one quantity by the other so that the denominator of the result is 1 (a unit). Often, we want the units of the independent variable in the denominator. Sometimes, we don't know what that is, because it depends on the intended use of the rate.
(14 h)/(2 wk) = 7 h/wk
__
When numerator and denominator have the same units, the result is a pure number (one with no units). If that number is a fraction, sometimes it is expressed as a percentage; other times, it is left as a fraction or written as a ratio with a colon, such as 1 : 35.
Here, both units are time, so the "unit rate" could be expressed as a fraction. We know there are 168 hours in a week, so this rate could be ...
(14 hours)/(2·168 hours) = 1/24 . . . . . with no units
Answer:
Y intercept = (0,10)
slope is 4
Step-by-step explanation:
Ok so Start with y intercept. That’s the point it crosses the y axis. So that would be ( 0, 10). To find slope, you do rise/run. Or how far up, and how far right. take two points (0,10) and (1, 14)
14-10
——-
1-0
= 4/1 = 4
so the slope is 4.
It has infinite solution because it has many problems solvers to solve with
