Answer:
45 mph
540 miles
Step-by-step explanation:
Given that :
Number of miles from home = 135 miles
Number of hours = 3 hours
Rate of change : Distance / Time
Rate of change = 135 miles / 3 hours
Rate of change = 45 miles per hour
Distance covered in 12 hours :
45 mph * 12 hours = 540 miles
Hence, In 12 hours Traci will be 540 miles from home
I am assuming the both cylinders have the same measure of radius. They only differ in height.
Larger Cylinder = 343 ft³
Smaller Cylinder = 125 ft³ ; height = 5 ft.
We can use proportion for this problem; a:b = c:d where ad = bc
5 ft :125 ft³ = x : 343ft³
5 ft * 343 ft³ = 125 ft³ * x
1715 ft⁴ = 125 ft³ * x
1715 ft⁴ ÷ 125 ft³ = x
13.72 ft = x height of the larger cylinder.
Cone S = 768pi cm³
Cone T = 6144pi cm³ ; height = 24 cm
24 cm : 6144 cm³ = x : 768 cm³
24 cm * 768 cm³ = 6144 cm³ * x
18,432 cm⁴ = 6144 cm³ * x
18,432 cm⁴ ÷ 6,144 cm³ = x
3 cm = x height of Cone S.
So since the problem says the number 46 is equal to something, you immediately know that your equation will look like this
46 = something
Now, when an unknown number is multiplied by a number, it has the number and a letter right next to it.
example. 23p
So since 23p = 46, your answer is B :) Hope this helped!
