eric can spend a maximum of $270 on office supplies. Each rem of paper costs $6. Each ink catridge costs $18. Which of the follo
Vladimir [108]
If we say A = ream of paper and B = cost of ink than we can set-up an expression to calculate when A is equal to a number what the number of B will be. Maximim of 270$ so anything we buy must be equal to this. Ream of paper cost 6$ each so 6A represents the number of reams bought since we said A is number of reams of paper. Ink Cartridges are 18$ each so 18B would represent this based on B = to cost of ink. Now setting up our equation 6A + 18B = 270 When A = 1 B = 14.67 Ink Cartridges When A = 1 Ream ofpaper

point Z in nXYZ has coordinates (5,-4). nXYZ was dilated by a scale factor of 0.8 name the coordinates of the image of point V.
cluponka [151]
There is no information given about point V, so any answer will do for the question asked.

If we assume the intent is to ask about the image of point Z, then its coordinates will be 0.8 times those of point Z.
  Z' = 0.8×(5, -4)
  Z' = (0.8×5, 0.8×(-4)) = (4, -3.2)

The appropriate choice seems to be
  C (4, -3.2)

15. A cylindrical glass 10 cm tall and 8 cm in diameter is filled to 1 cm
ANTONII [103]

Answer:

No. The new height of the water is less than the height of the glass(6.33 cm<10 cm)

Step-by-step explanation:

-For the water in the glass to overflow, the volume of the inserted solid must be greater than the volume of the empty space or the ensuing height of  water >height of glass.

#Volume of the golf ball:

V=\frac{4}{3}\pi r^3\\\\=\frac{4}{3}\pi \times 4^3\\\\\approx 268.08\ cm^3

#The volume of the water in the glass:

V=\pi r^2 h\\\\=\pi \times 4^2\times 10\\\\\approx 50.27\ cm^2

We then equate the two volumes to the glass' volume to determine the new height of the water:

V=\pi r^2h\\\\(206.08+50.27)=\pi r^2 h\\\\h=318.35/(\pi \times 4^2)\\\\=6.33\ cm

Hence, the glass will not overflow since the new height of the water is less than the height of the glass(6.33 cm<10cm).

Jacob is a plumber. Due to increased material costs, he puts all his prices up by 7%. He now chargers R320 per hour for her serv
Lorico [155]

Answer:

R290.1

Step-by-step explanation:

Let

x = charge before he put his prices up

New charge = R320

Percentage increase in price = 7%

x + 7% of x = 320

x + 0.07 * x = 320

x + 0.07x = 320

1.07x = 320

x = 320/1.07

x = 299.06542056074

Approximately

x = R290.1

Charge before he put his prices up = R290.1
