Answer:
15 more are not woodwinds than woodwinds
Step-by-step explanation:
If there are 8woodwinds out of 21instruments, to know the number of woodwinds when we have 63instruments can be gotten as shown below;
8woodwinds = 21instruments
x woodwinds = 63instruments
Cross multiplying we will have;
x woodwinds × 21instruments = 8 woodwinds × 63instruments
x woodwinds = 8woodwimds × 63instruments/ 21instruments
x = 8×63/21
x = 24
This shows that there will be 24 woodwinds if there are 63 instruments
If there are 24woodwinds, number of those not woodwinds will be;
63-24 = 39
Therefore we have 24woodwinds and 39 that are not woodwinds.
To know how many more instruments that are not woodwinds than woodwinds, we will take the difference between those not woodwinds and those of woodwinds to give;
39-24 = 15
This shows 15 more are not woodwinds than woodwinds
Answer:
Total distance traveled by annie is mile.
Step-by-step explanation:
Distance covered by annie to her friend's house is
mile.
After there , annie and her friend travelled mile to the library.
We have to find the total distance covered by annie which can be find by adding total distance traveled by her,
Total distance traveled by annie = distance traveled to friend's house + distance traveled to library.
=
Solving it further, we get
=
=
Thus, Total distance traveled by annie is mile.
How many miles can Sarah travel in 6 hours
The equation relating distance, d, to time, t, is given by d = 55t, where 55 is the constant of variation. Sarah can travel 330 miles in 6 hours by substituting t = 6 into the equation d = 55t.
The equation that relates the distance, d, to the time, t, when they vary directly is:
d = k * t
where k represents the constant of variation.
To find the value of k, we can use the given information. Sarah travels 440 miles in 8 hours. Substituting these values into the equation:
440 = k * 8
Dividing both sides by 8:
k = 440 / 8
k = 55
Therefore, the equation that relates the distance, d, to the time, t, is:
d = 55t
To find how many miles Sarah can travel in 6 hours, we substitute t = 6 into the equation:
d = 55 * 6
d = 330
Therefore, Sarah can travel 330 miles in 6 hours.

Answer:
d=55t Sara travels 330 miles
Step-by-step explanation:
We are given that distance, d, Sarah drives varies directly to the time, t. This means
d=k⋅t
for some constant, k. Since Sarah travels 440 miles in 8 hours, we substitute these values into the formula for direct variation to find
440=k⋅8
Dividing by 8 gives k=55, so an equation that relates d and t is
d=55t
Substituting t=6 yields
55(6)=330
So Sarah can travel 330 miles in 6 hours.
