What is the answer for the three questions please help

The driver can drive around the track 54 times for $12. Thus for one dollar, he can drive around the track 54/12 times, or 4.5 times. If for each dollar he drives around 4.5 times, for 8 dollars, he can drive around 8*4.5 or 36 times.

If there are 207 students in 9 classes, in 1 class, there are 207/9 students, or 23 students per class. Since there are 23 students per class and there are  classes, there are a total of 23*6 or 138 students in total.

Liam practices 24 times in 4 days. Thus he practices 24/4 or 6 times per day. His brother practices 12 times in 3 days. Thus he practices 12/3 or 4 times a day. Thus their rates are not equivalent.

HELP!
tigry1 [53]

Answer:

b=40.01\ units

Step-by-step explanation:

we know that

Applying the law of sines

\frac{b}{sin(B)}=\frac{a}{sin(A)}

b=\frac{a}{sin(A)}(sin(B))

we have

a=25\ units

A=32.5\°

Find the measure of angle B

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

so

A+B+C=180\°

substitute the given values

32.5\°+B+26.8\°=180\°

B=180\°-59.3\°=120.7\°

Find the length side b

b=\frac{a}{sin(A)}(sin(B))

substitute the values

b=\frac{25}{sin(32.5\°)}(sin(120.7\°))

b=40.01\ units

Find the diameter of the circle with the given circumference. Use 3.14 . C=16 cm
Daniel [21]

Answer:

5.1 cm

Step-by-step explanation:

The equation for the circumference of a circle is 2πr or πd.

So, we can plug in 16 and 3.14 to get 16 = 3.14×diameter.

Divide both sides by 3.14 to get approximately 5.1 cm.

Hope that helps! :)
