1:</h2>
- A mile unit is equal to 1760 yards. inches =mile * 63360 2*63360=126720
2 Miles = 126720 Inches
- There are 36 inches in a yard
3600/36= 100
3600 inches = 100 yards
6800/1000 = 6.8
6800 m = 6.8 km
15000/100=150
15000 cm=150 m
2:
a) Johnson ran yard in second= 9
1 minute = 60 second
Johnson ran yard in one minute= 9 *60= 540 yards
b) Johnson ran yard in second= 9
1 hour = 60 minutes *60 second= 1200 seconds
Johnson ran yard in one hour= 9 *1200= 10,800 yards
c) Johnson ran yard in one hour= 9 *1200= 10,800 yards
1 mile = 1760 yards
miles did he run in one hour= 10,800 / 1760 =6
Johnson ran 6 mile in one hour
The feeders in battling machine are represented in proportions and fractions.
- The equation that represents the problem is:
- The feeder can hold <em>30 baseballs</em>, when full
The given parameters are:
<em />
<em> ------ 1/6 full</em>
<em />
<em> --- baseballs added</em>
<em />
<em> ---- 2/3 full</em>
<em />
So, the equation that represents the problem is:
So, we have:
The number of baseballs it can hold is calculated as follows:
Multiply through by 6
Collect like terms
Divide through by 3
Hence, the feeder can hold 30 baseballs, when full

Answer:
13.448, rounded off: 13.5 ft
Step-by-step explanation:
Where r = radius, C = circumference.
= 13.5 ft
Well u have a basic equation y=a • b^x
a is the initial amount
b is the growth factor
and x is the exponent
the first step is to make a chart with ur two points for example
(0,4) and (2,16)
so ur chart will be
x. | y.
0. | 4
2. | 16
next you find the difference between the x side so 0 to 2 is +2
then find the difference between the y side so 4 to 16 is +12
then put it into a fraction with y over x or y/x so 12/2 then simplified 6/1 or just 6.
6 is the growth factor
and to find a u have to go on the y column and find the first number so
a is 4
x is still x because it's 0 but if it was 2 then it would be x-2 so it can cancel
so the answer would be y=4 • 6^x
Hope this is what you are looking for the answer is 2(15-2n)
