Answer:
108 hours and 15 minutes
Step-by-step explanation:
Answer:
C (Y = -5/8x - 10)
Step-by-step explanation:
first find the slope (y₂ - y₁) ÷ (x₂ - x₁)
(5 - (-20)) ÷ (-24 - 16)
-5/8 = slope (m)
now that we know the slope is -5/8 we can rule out A and B
now to find the y intercept just substitute a point in for x and y
5 = (-5/8)(-24) + b
multiply
5 = 15 + b
subtract 15 from both sides tp isolate b
-10 = b
Answer:
40
Step-by-step explanation: Total distance = 60 miles
Total time = 30 / 30 + 30/60 = 3/2
Avg. speed = 40.
<span>1) If we mix up 350g of sugar with some water to make 70% sugar syrup, then
70% of sugar syrup weight is equal to weight of sugar, i.e. 350g
total weight of sugar syrup will be
350 * 100/70 = 500 g
2) Similarly, total weight of 30% sugar syrup made with 75g of sugar will be
75 * 100/30 = 250 g</span>
