Total songs = 1240 
Rock songs = 40%
Songs that are not rock = 100 - 40 = 60%

It would be: 1240 * 60% = 1240 * 0.60 = 744

In short, Your Answer would be 744

Hope this helps!

An isosceles triangle has an angle that measures 38degrees. What measures are possible for the other two angles? Choose all that
Sphinxa [80]

Answer:

  • 71° and 71°.

⠀

Step-by-step explanation:

The triangle having two sides equal along with one different side is called an isosceles triangle.

⠀

  • So, Let us assume the other sides (two equal sides) of the isosceles triangle as x. As the different side is already given in the question.

⠀

We know that,

  • The sum of all angles of a triangle is 180°

⠀

So, According to the question :

⠀

{\longrightarrow \it\qquad { \ { {  38 \: }^{ \circ}   + x + x  =  180{}^{ \circ} }}}

⠀

{\longrightarrow \it\qquad { \ { {  38 \: }^{ \circ}   + 2x   =  180{}^{ \circ} }}}

⠀

{\longrightarrow \it\qquad { \ {   2x   =  180{}^{ \circ} - {  38 \: }^{ \circ}}}}

⠀

{\longrightarrow \it\qquad { \ {   2x   =  142{}^{ \circ}  }}}

⠀

{\longrightarrow \it\qquad { \ {   x   =    \dfrac{142{}^{ \circ}}{2}   }}}

⠀

{\longrightarrow \it\qquad { \pmb {   x   =  71^{ \circ}  }}}

⠀

Therefore,

  • The measure of the two other angles of the isosceles triangle are 71° and 71°.

Nathans drive to and from work each day is about 45 miles if he goes to work 226 days in a given year what is the minimal amount
enot [183]

Answer: The minimum amount that Nathan will pay including extra charges for exceeding mileage limit is $5,598.50¢

Step-by-step explanation:

Since Nathan went to work for 226 days, covering 45 miles daily to and from work with the car he leased from the leasing company, he therefore covered a total of:

45 × 226

= 10170 miles.

He covered a total of 10170 miles in that particular year.

If the mileage limit was 10,000 miles, then the additional miles that will attract extra charges will be derived by subtracting the mileage limit from the total miles covered within the given period =

10170 - 10,000

= 170 miles

If the extra mile charge on every mile that exceeds the mileage limit was set at $0.25 per mile, then the amount that Nathan will pay for only exceeding the mileage limit within the year =

0.25 × 170

= $42.50

Again, if leasing a car from the company attracts a monthly payment of $463, the amount that is expected of Nathan to pay for leasing the car from the company for the year is then:

$463 × 12 months

= $5,556

The minimum amount that Nathan will pay for the car in that particular year including charges for exceeding the mileage limit will then be:-

$5,556 + $42.5

= $5,598.50
