Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7
i hope this helps!
Answer:
f(x) = - 2x - 1
Step-by-step explanation:
Let the linear function f(x) is given by f(x) = ax + b where a and b are unknown constants.
Given that f(0) = -1 and f(2) = -5
Hence, a(0) + b = - 1, ⇒ b = - 1
Again from the condition given
a(2) + b = -5, ⇒ 2a - 1 = - 5, ⇒ 2a = - 4, ⇒ a = - 2.
Therefore, the linear function is f(x) = - 2x - 1 (Answer)
An hour is 60 mins long. 30 mins is half of it. If we take 12 miles in an hour, divide it by 2, it will be 6 miles in 30 mins, and if we take 8 miles, divide it by 2, it would be 4 miles in 30 mins. Since the questions telling us how far apart are north cyclists, we’re adding 6 and 4 to get 10 miles. In conclusion, both cyclists are 10 miles apart. I might be wrong, but that’s the best I can do.
