Answer:
1470 square feet
Step-by-step explanation:
15x10 =150
132×10=1320
total =1479
Answer: 15 / 56
Step-by-step explanation:
Number of red checkers = 3
Number of black checkers = 5
Total number of checkers = 8
P(black, then red) = 5/8 × 3/7 = 15/56
We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
____________________________________
Total Numbers
15 = 3 + 19 + 8 + 32 + x
______________
5
Cross Multiply
___________
3 + 19 + 8 + 32 + = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
Answer:
12
Step-by-step explanation:
For our problem since we only in 10 am:
I'm going to let x=4 represent the time 10:04 am
which means I'm going to let x=17 represent 10:17am.
So when x=4, y=23 miles and when x=17,y=179 miles.
You have two points.
You can use the formula 
.
Or just line the points up vertically and subtract them vertically, then put 2nd difference over first difference. Like this:
( 17 , 179)
-( 4 , 23)
-----------------------
13 156
So the slope is 156/13=12 miles/hour.
