We know, 1 mile is equal to 1760 yards
So, Thomas run [tex]2\times 1760=3520\ \text{yards}[/tex]

The cost of 3 loaves of bread and 3 gallons of milk is $19.35. The cost of 4
loaves of bread and 2 gallons of milk is $17.90. How much does one loaf
of bread cost?
Answers
Answer:
bread $2.5 milk $3.95
Step-by-step explanation:
b=bread m= milk
3b +3m = 19.35
4b+2m= 17.90
Multiply the first by (-2)
Multiply the second by 3
Then add both
-6b -6m = -38.7
12b+6m=53.7
(when you add both 6m is cancelled)
6b = 15
b= 2.5 (BREAD $2.5)
4(2.5) = 10
10+ 2m = 17.90
2m = 7.90
m= 3.95 (MILK $3.95)

Answers
Answer:
Median = 6.1875
Mean = 6.375
Step-by-step explanation:
Given the data:
8 1/2,6 5/8,3 1/8,5 3/4,6 5/8,5 1/4,10 5/8,4 1/2
Arranging in ascending order :
3 1/8, 4 1/2, 5 1/4, 5 3/4, 6 5/8, 6 5/8, 8 1/2, 10 5/8
Median = 1/2(n + 1)th term
n = 8
1/2 (9) th term
= 4.5th term
(5 3/4 + 6 5/8) / 2
= 6.1875
Mean = Σx / n
Mean = 51 / 8
Mean = 6.375
function h describes the height of a ball, in inches, after n bounces and is defined by the equation h(n)=120 x (4/5)^n.
What is h(3) ?
What does h(3) represent in this situation?
Answers
Answer:
Step-by-step explanation:
h(3) = 120*(4/5)^3, which evaluates to 120(64/125), or 61.64.

1. Arun can walk 15 km in 3 hours. How far can he
walk in 4 hours?
Answers
Answer:
Step-by-step explanation:
15/3 = x/4
if you multiply you get 3x= 4*15.
4 times 15 is 60, then divide by 3 to get 20
Arun can walk 20 km in 4 hours.
Answer:
20 km.
Step-by-step explanation:
First, divide 15 by 3 to find out how many kilometers Arun can walk in a single hour.
15/3=5
To find out how far he can walk in 4 hours, multiply 4 by the number of kilometers he can walk in an hour, which is 5.
4x5=20
Therefore, Arun can walk 20 km in 4 hours.

What are the integer solutions to the inequality below? 3 < 3 x − 1 < 2 x + 6
Answers
Answer:
4/3<x<7
Step-by-step explanation:
Given the inequalities
3 < 3 x − 1 < 2 x + 6
Add 1 to all sides
3+1 < 3x-1+1<2x+6+1
4 < 3x < 2x + 7
Split
4 < 3x
3x > 4
x > 4/3
4/3 <x
Also
3x < 2x + 7
3x-2x < 7
x <7
Combine
4/3<x<7
Hence the required solution is 4/3<x<7
