delilah dose 184 jumping jacks in 4 minutes she dose her jumping jacks at a constant rate how many jumping jacks can delilah do per minute

46 jumping jacks per minute

Step-by-step explanation: Divide the total number of jumping jacks (184) by the time (4 minutes). Since she is going at a constant rate, this would be equal to 46 jumping jacks per minute. On a coordinate plane, this would be a linear function.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:
