Let A represent the speed of car A. Using your formula,
.. A*2 = D
.. (A +15)*1.5 = D . . . . . the same distance in a shorter time at a higher speed
Equating the two expressions for D, we get
.. 2A = 1.5(A +15)
.. 2A = 1.5A +22.5 . . . . . eliminate parentheses
.. 0.5A = 22.5 . . . . . . . . .subtract 1.5A
.. A = 22.5/0.5 = 45 . . . .divide by 0.5
Car B was 15 mph faster than this.
Car B traveled at 60 miles per hour.
3. x: 180-99 = 81º (angles on a straight line equals 180)
y: 115-81 = 34º (exterior angle is sum of opposite interior angles)
4. y: 180-64 = 116 (angles on a straight line equals 180)
x: 126º
two steps
angles on straight line equals 180: 180-118 = 62º
exterior angle is sum of opposite interior angles: 62+64 = 126º
sorry if i misread any of the numbers, let me know if i did and i'll fix it
Answer:
The question is not complete, nut here is the complete question ; A company produces alarm clocks. During the regular workweek, the labor cost for producing one clock is $4.00. However, if a clock is produced on overtime, the labor cost is $5.00. Management has decided to spend no more than a total of $51,000 per week for labor. The company must produce 12,000 clocks this week. What is the minimum number of clocks that must be produced during the regular workweek?
Step-by-step explanation:
Tthe detailed analysis and step by step calculation is as shown in the attached file.
0.45 as a fraction is
45/100 and in simplest form it is
9/20.
Oh. It's rounding. So, for example, depending what you were told to round to, the second problem would be 760-330=430
