<h3>Answer:  15 miles</h3>

===========================================

Work Shown:

t = time it takes to go from Jackie's house to her friends house

distance = rate*time

d = 30*t

This represents the distance they travel if they go 30 mph

Then when going back home, they take 6 minutes longer

6 minutes = 6/60 = 0.1 hours

So they take 0.1 hours longer meaning the t updates to t+0.1

d = r*t

d = 25*(t+0.1)

d = 25t+2.5

This represents the trip back home.

Since the distance d doesn't change, we can equate the two right hand sides and solve for t

30t = 25t+2.5

30t-25t = 2.5

5t = 2.5

t = 2.5/5

t = 0.5 hours = 30 minutes

d = 30t = 30*0.5 = 15 miles

Simplify this expression
Sergeu [11.5K]

Answer:

option 4

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} = \sqrt{ab}

Given

(2 - 5\sqrt{6} ) 3\sqrt{2} ← distribute parenthesis by 3\sqrt{2}

= 6\sqrt{2} - 15\sqrt{12}

= 6\sqrt{2} - 15\sqrt{4(3)}

= 6\sqrt{2} - 15(\sqrt{4} × \sqrt{3} )

= 6\sqrt{2} - 15(2\sqrt{3} )

= 6\sqrt{2} - 30\sqrt{3}

Maria’s family hosts a barbeque every month in the summer. In May, they bought 3.2 pounds of hamburger and 3 packages of hot dog
Sindrei [870]
Given:

May:
hamburger: 3.2 pounds * 4.25 = 13.60
hotdogs:     3 packages * 4      = 12
Total cost: 13.60 + 12 = 25.60

June:
hamburger: 3.2 pounds * 1 1/2 = 4.8 pounds * 4.25 = 20.4
hotdogs:      3 packages * 1/3    = 1 package * 4        =   4
Total cost: 20.4 + 4 = 24.4

25.60 - 24.40 = 1.20

They spent more on May by $1.20. Choice C.

A man invested one fifth of his money at 4%, half of his money at 5%, and the rest of his money at 3.5%. If his total annual inv
Ksivusya [100]
The man invested 1/5 of the money at 4/100. Which says he earns 4/500 of his total money on one month.

He also invested 1/2 of the money at 5/100. Which means he earns 5/200 of his total money per month.

For the last part, he spent the rest of the money which is: x + 1/5 + 1/2 = 1
Make the denominators equal: x + 2/10 + 5/10 = 10/10
Add like terms: x + 7/10 = 10/10
Substract 7/10: x=3/10

He gave this money for 3.5/100 interest. Which equals 10.5/1000 of his total money.

When you add the three values: 4/500 + 5/200 + 10.5/1000
Make denominators equal: 8/1000 + 25/1000 + 10.5/1000
Add the like terms: 43.5/1000

This means the man's money's 43.5/1000 is equal to $870

Set the values equal: 43.5x/1000 = 870
Make the denominators equal: 43.5x/1000 = 870,000/1000
Multiply with 1000: 43.5x = 870,000
Divide both sides by 43.5: x = 20,000

The man's total money is $20,000
