3. 77 miles
4. 150 minutes
5. 270 miles
6. 20 yd per min.
7. 1200 miles
8. 14 ft. per min.
9. 2 hours.
10. 3 hours max. (unless u count traffic)
11. No, it will take 3 hours and 30 minutes.
d=rt
d/r=t
d/t=r
basically if given 2 of the, you can find the rest with
d=rt
t=d/r
r=d/t
2. speed=r
d=3600m
t=12
r=d/t
r=3600m/12m
r=300m/min
rate=300m per minute
3. the time is 7 hours
speed =11mph=r
d=rt
d=7h times 11mph
d=77miles
4. given
d=300cm
r=2cmpermin
t=d/r
t=300cm/2cmpermin
t=150min
5. r=45mph
t=6h
d=rt
d=45mph times 6h
d=270miles
6. d=400yd
t=20min
r=d/t
r=400yd/20min
r=20yd/min
r=20yards per minute
7. r=120mph
t=10h
d=rt
d=120mph times 10h
d=1200miles
8. d=700ft
t=50min
r=d/t
r=700ft/50min
r=14ft/min
r=14 feet per minute
9. d==1200mi
r=600mph
t=d/r
t=1200mi/600mph
t=2h
t=2 hours
10. speed limit is 65mph=r
d=195miles
t=?
t=d/r
t=195mi/65mph
t=3 hours
11. 2 ways
1. find how far it travels in 4 hours
2. find how long it will take
both easy, I willl do first
in 4 hours
d=rt
d=4h times 65mph
d=260 miles
260mi>230mi
yes

The two little lines through the sides of AB and CB mean that they are the same length.
Because the two sides are the same length angle A and Angle C are also the same, so those are both 73 degrees.
The three inside angles of a triangle need to equal 180 degrees, so we know angle B would equal 180 - 73 - 73 = 34 degrees.
Now we can set the equation for angle B equal to 34 and solve for x.
6x+4 = 34
Subtract 4 from each side:
6x = 30
Divide both sides by 6:
x = 30/6
x = 5

Answer:
$38,144.33
Step-by-step explanation:
Represent the problem in an equation:
let x be salary before wage cut.
x - x(0.03) = 37,000 <= 3% in decimal form is 0.03
1x - 0.03x = 37,000
Combine like terms (any terms with variable x)
0.97x = 37,000
x = 38,144.329 <= round this answer
x = 38,144.33
Therefore, the average salary before the wage cut was $38,144.33.

[number of rows (across) x number of columns (up and down)]
There is 1 row and 4 columns, hence the dimensions of [1 x 4]
#71: use factor/label conversion method.
480 minutes 1 hour 480 hours 8 hours
* -------------- = -------------- =
60 minutes 60 minutes
#72: common difference is how you get from one number to the next in the sequence. So from 42 to 38, you subtract 4, and the pattern is subtract 4 for the whole sequence. So the common difference is -4
#38: The midpoint is the middle of the two coordinates, so imagine when used to find mean by drawing a number line like 1 to 10 and the mean would be 5. What did you do? You added 1 and 10 and divided by 2.
You can use the same method for finding midpoints on the coordinate plane.
The formula for midpoint is (x1+x2),(y1+y2). So it's (5 + 2) , (8 + 7) which equals (7, 15).
#35: This is the same 3* x^(9*1/5) = 3*x^9/5
Remember square root of a number is the same as that number to the 1/2, and the same with all other roots. The fifth root of x is the same as x to the power of 1/5
#36: This is the same as 36*( x^5*3/2 * y^3*3/2), since you can put the power to each of the numbers almost like the distributive property.
= 36 * (x^15/2 * y^9/2)
Well #20 is extremely easy. The solutions are anything that is shaded in the blue
The rightmost question is the same thing as #20. Anything not shaded is not a solution.
#64: Just like you learned in elementary school, the median is the middle number. The middle number is 10
