Answer:
see the explanation
Step-by-step explanation:
we know that
An extended ratio compares three or more numbers.
In the extended ratio a:b:c
The ratio of the first two numbers is a:b (you can write a to b or a/b)
The ratio of the last two numbers is b:c (you can write b to c or b/c)
The ratio of the first and last numbers are a:c (you can write a to c or a/c)
Answer:
Step-by-step explanation:
If y varies directly as x, then we can write the relation
where k is the constant of proportionality.
We substitute y=-319 when x=29.
This implies that:
The variation equation now becomes
12s + 8i is one of the answers. Sorry, I don’t know the other :/
Answer:
199 if it's 7b^3 + 10
9271 if it's (7b)^3 + 10
Step-by-step explanation:
You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.
So 3^3 is 27, 27*7 is 189, 189+10 is 199.
If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.
Your answer is going to be 20 19/20
