Answer:

2 miles 2 yards

Step-by-step explanation:

There are 1760 yards in a mile, so you are effectively performing the division ...

(9185 380/1760) ÷ 4590

where the number in parentheses is a mixed number of miles.

You do this division the same way you do any mixed-number division. There are different possible methods you can use. One of them is to convert the mixed number to an improper fraction, then divide.

9185 380/1760 = 9185 19/88 = (88·9185 +19)/88 = 808299/88

Then this is divided in the usual way:

$\dfrac{808299}{88}\div4590=\dfrac{808299}{88\cdot4590}=\dfrac{808299}{403920}=2\dfrac{459}{403920}=2\dfrac{1}{880}$

Finding the quotient and remainder is straightforward. Reducing the fraction involves finding common factors in the numerator and denominator. As it turns out, 459 is a factor of 403920, so the fraction reduces as shown.

Now, we need to convert 1/880 miles back to yards.

((1/880) mi) × (1760 yd/mi) = 2 yd

So, the quotient you seek is ...

2 miles 2 yards

1. Mark is six years older than his brother Sam. The sum of their ages is 30. What a be Sam's age. Set up and solve an equation

barxatty [35]

Answer:

1) Sam's age = a = 12

Mark's age = 18

2) Number of tickets Mandy sells = N = 12

Number of tickets Alonso sells = 31

3) Number of points Elena scores = a = 12

Number of points Karla scores = 24

Number of points Faye scores = 42

Faye scores more points!

Step-by-step explanation:

1) Let a represent Sam's age

Mark's age = a + 6

Sum of their ages = 30

a + (a + 6) = 30

2a + 6 = 30

2a = 24

a = 12 year old

a + 6 = 12 + 6 = 18 year old

Sam's age = 12

Mark's age = 18

2) Let N represent the number of tickets that Mandy sells

Alonso sells five tickets less than three times Mandy sells, that is equal to (3N - 5) tickets.

Total number of tickets sold = 43

N + 3N - 5 = 43

4N = 48

N = 12 tickets

3N - 5 = 36 - 5 = 31 tickets

Number of tickets Mandy sells = N = 12

Number of tickets Alonso sells = 31

3) Let the number of points Elena scores = a

Number of points Karla scores = 2a

Number of points Faye scores = a + 30

Total number of points = 114

a + 2a + a + 30 = 114

4a = 114 - 30 = 84

4a = 84

a = 12 points

2a = 24 points

a + 30 = 42 points

Number of points Elena scores = a = 12

Number of points Karla scores = 24

Number of points Faye scores = 42

Since 42>24, Faye evidently scores more points than Carla.

A rancher constructs two rectangular horse pastures that share a side, as shown. The pastures are enclosed by 1050 feet of fenci

noname [10]

The complete question in the attached figure

we know that
area each pasture=15000 ft²
area each pasture=x*y
so
15000=x*y-----> equation 1

perimeter two rectangular pastures=1050 ft
perimeter two rectangular pastures=2*[2x+y]+y----> 4x+2y+y---> 4x+3y
so
1050=4x+3y----> divide by 3----> 1050/3=(4/3)x+y
clear variable y
y=350-(4/3)x-----> equation 2

the answer part a)
y=350-(4/3)x------> <span>it was proved
</span>
Part b)Find the possible lengths and widths of each pasture.
substitute equation 2 in equation 1
15000=x*y-----> 15000=x*[350-(4/3)x]
15000=350x-(4/3)x²----> multiply by 3----> 45000=1050x-4x²
4x²-1050x+45000=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is
x=53.942 ft
x=208.558 ft

15000=x*y-----> y=15000/x

for x=53.94 ft
y=278.09 ft

for x=208.56 ft
y=71.92 ft

the possible lengths and widths of each pasture are
case 1
x=53.94 ft
y=278.09 ft

case 2
x=208.56 ft
y=71.92 ft
