An online data base charges $25 an hour during the day and $12.50 an hour at night. If a research company paid $250 for 12 hours
Firdavs [7]

Answer

Find out the  which system of equations could be used to determine the number of hours charged at the day rate (d) and at the night rate (n) .

To proof

As given in the question

Let us assume that the number of hours charged at the day rate = d

Let us assume that the number of hours charged at the night rate = n

An online data base charges $25 an hour during the day and $12.50 an hour at night. If a research company paid $250 for 12 hours of use.

Total working hour in a company including day and night be  12 hours .

than the equation become in the form

d + n = 12

also

An online data base charges $25 an hour during the day

$12.50 an hour at night.

If a research company paid $250 for 12 hours of use.

than the equation becomes

25d + 12.50n = 250

than the two equation are

d + n = 12 , 25d + 12.50n = 250

multiply first by 25 and subtracted  from 25d + 12.50n = 250

25d - 25d + 12.50n - 25n = 250 - 300

12.5 n = 50

n = \frac{50}{12.5}

n = 4hours

put this in the d + n = 12

d + 4 =12

d = 12-4

d = 8 hours

Therefore the number of hours charged at the day rate  is 8 hours  and at the night rate is  4hours .

Hence proved

Mama L [17]

Answer:

180 m²

Step-by-step explanation:

Surface area = 2 ( lw + wh + lh)

                     = 2( 6x3 + 3x8+8x6)

                      = 180 m²

Find the product.
natka813 [3]

Answer:

C:) 17/3

Step-by-step explanation:

Simplify the following:

((3 + 2/5)×5)/3

((3 + 2/5)×5)/3 = ((3 + 2/5)×5)/3:

((3 + 2/5)×5)/3

Put 3 + 2/5 over the common denominator 5. 3 + 2/5 = (5×3)/5 + 2/5:

((5×3)/5 + 2/5 5)/3

5×3 = 15:

((15/5 + 2/5)×5)/3

15/5 + 2/5 = (15 + 2)/5:

((15 + 2)/5×5)/3

15 + 2 = 17:

(17/5×5)/3

17/5×5 = (17×5)/5:

((17×5)/5)/3

((17×5)/5)/3 = (17×5)/(5×3):

(17×5)/(5×3)

(17×5)/(5×3) = 5/5×17/3 = 17/3:

Answer:  17/3

The boiling point of jet fuel is 329°
natka813 [3]

Since, the boiling point of jet fuel  = 329 °F

We have to convert the boiling point of jet fuel in ^\circ C.

The expression which is used to convert ^\circ F to ^\circ C is given by:

C = \frac{5}{9}(F-32)

= \frac{5}{9}(329-32)

= \frac{5}{9}(297)

= 165^\circ C

Therefore, the boiling point of jet fuel is 165 ^\circ C.
