So in order to solve this problem we first have to divided
840 divided by 12 is 70
So that means that Andy drives 70 miles per hour
We need to find out how much miles Andy drives in 3 hours so we have to multiply the number of miles he drives per hour by 3
70*3=210
Therefore,Andy drives 210 miles in 3 hours

To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.

If BAC = 320°, what is the measure of BC?
melisa1 [442]

Answer:

BC = 40º

BMC = 40º

Step-by-step explanation: Since the measure the major and minor arcs add up to 360º, just subtract 320 from 360 to find BC which is 40º. <BMC is also 40º because the measure of the arc is equal to its corresponding angle.

Finding zeros or setting y ot f(n) equal to zero
 
and all you have to do is factor it, hoping you know how to do this

5. 0= n^2-2n-15
(n-5)(n+3)= 0
n-5= 0              n+3=0 
n=5 and n=-3

6.t^2+6t=27
t^2+6t-27=0
(t + 9) (t-3)= 0 
t=-9 and t=3

7. x^2-9x=-18
x^2-9x+18=0
(x-6)(x-3)= 0 
x=6 and x=3

8. a^2 - 7a = 30

a^2 - 7a -30= 0
(a-10)(a+3)=0
a=10 and a=-3

hope that helps
