Answer:
52.24 km
Step-by-step explanation:
Given that,
The distance needed to stop a car, d, varies directly as the square of the speed, s, at which it is travelling.
d = ks²
Where
k is constant
When s₁ = 70 km/hr, d₁ = 40 m, s₂ = 80 km/hr, d₂ = ?
So,
So, the new distance is 52.24 km.
Answer:
Hallie ride 62 miles on bicycle.
Step-by-step explanation:
Given:
Let the number of miles Samantha rode be 'x'.
Hallie rode her bicycle 7 miles less than 3 times the number of miles Samantha rode.
It means that number of miles Hallie ride is equal to 3 multiplied by number of miles Samantha rode and then subtracting by 7.
framing in equation form we get;
number of miles Hallie ride =
But Given:
number of miles Samantha rode =23 miles.
Now by substituting the value of in above equation we get;
number of miles Hallie ride =
Hence Hallie ride 62 miles on bicycle.
75,000 I’m 100% sure
What you do it 300 divided by 4% times 10
Answer:
It's simple, just divide the smaller by the larger number. If you wanted to find, let's say, 25 out of 75 as a percent, you would just do this.
Step-by-step explanation:
25 ÷ 75 = 0.3333
0.3333 x 100 = 33.33
Or 33.33%
Another example
12 ÷ 50 = 0.24
0.24 x 100 = 24
Or 24%
Hope this helps!
