Hey there! :)
Answer:
First part: 2 miles.
Second part: 45 minutes
Third part: 8 mph.
Step-by-step explanation:
We can divide this question into 3 parts.
Begin by solving for the distance traveled after 15 minutes by creating a ratio:
Cross multiply:
20 · 15 = 150 · x
300 = 150x
300/150 = 150x/150
x = 2 miles.
2nd part: How long it took her to ride 6 miles.
Set up another ratio similar to the one used before:
Cross multiply:
20 · x = 6 · 150
20x = 900
20x/20 = 900/20
x = 45 minutes.
3rd part:
For this part, we will need to convert from minutes to hours.
Therefore, her speed is 8 mph.
Answer:
16
Step-by-step explanation:
The two angle created by the bisector have equal measures, so ...
m∠ABD = m∠DBC
2y = 5y -12
0 = 3y -12
0 = y -4
4 = y
2y = 2·4 = 8
m∠ABC = 2×m∠ABD = 2×8
m∠ABC = 16
_____
We presume the angle measures are in degrees, though that is not specified by the problem given here. These numbers could all be radians, but 16 radians is more than a couple of times around the circle.
Answer:
its 120 your supposed to divide 120 ÷ 100% and ur answer will be 120
Answer:
If the length of x is less than 200, then add <.
If the length of x is more than 200, then add >.
If the length of x is 200, then add =.
