A car costs $3,500 and costs $4 in gas to drive fifteen miles. If another car costs $4,500 but only need $2 in gas to drive fifteen miles, after how many miles of driving would be the total cost of driving both cars be equal?

Answers

Answer 1

Answer:

500 miles

Step-by-step explanation:

Step one:

A car costs $3,500 and costs $4 in gas to drive fifteen miles

let the total cost be y and let the number of miles be x

y= 3500+4x-----------1

If another car costs $4,500 but only need $2 in gas to drive fifteen miles,

let the total cost be y and let the number of miles be x

y= 4500+2x----------------2

Step two:

Equate the two expressions for the total cost

3500+4x=4500+2x

solve for x

4x-2x=4500-3500

2x= 1000

divide both sides by 2

x= 1000/2

x= 500 miles

She believes that if she and her mother found the right kind of prodigy for Jing-mei, then Jing-mei would one day become a perfect child. As she begins losing hope, however, Jing-mei's character starts to change.

if f is a linear function, f(k)=16 and f(-k)= -4 then what is the value of f(0)?​

Answers

f(0) =  ( f(k) +f(-k) ) / 2

f(0) = (16 - 4) / 2

f(0) = 12 / 2

f(0) = 6  → ANSWER

*Remember that f(0) = m(0) + n = n

If we have f(x) = mx + n, then:

f(k)= mk + n     and       f(-k)= -mk + n

If we add them:

  f(k) + f(-k)

= mk + n -mk + n

= 2n

= 2f(0)

So we conclude that:

f(0) = [f(k) + f(-k)] / 2

r = [tex]\frac{16}{5}[/tex] ÷ 4 = [tex]\frac{4}{5}[/tex]

What is the radius of a hemisphere with a volume of 324\text{ ft}^3,324 ft 3 , to the nearest tenth of a foot?

Answers

Answer:

5.4 ft

Step-by-step explanation:

Given that the volume of the hemisphere sphere, [tex]V= 324 ft^3[/tex].

Let r be the radius of the hemisphere.

As the volume of the hemisphere, [tex]V=\frac {2}{3}\pi r^3[/tex]

By using the given value, we have

[tex]\frac {2}{3}\pi r^3=324[/tex]

[tex]\Rightarrow r^3=\frac{324\times 3}{2\pi} \\\\\Rightarrow r^3=\frac{324\times 3}{2\times3.14} \\\\\Rightarrow r^3=154.78 \\\\\Rightarrow r=\left( 154.78 \right)^{1/3} \\\\[/tex]

[tex]\Rightarrow r=5.4[/tex] ft

Hence, the radius of the hemisphere is 5.4 ft.
