Jordan saved 4/5 of the amount he needs to buy a $80 video game. If he earns $7.75 per hour by working at a pizza shop, how many hours does he need to work to save the rest of the money for the video game? round to the nearest hour

Answers

Answer 1

Answer: Amount of money saved by Jordon for the video game = (4/5) * 80
      = 4 * 16 dollars
   = 64 dollars
So
The amount of money that
Jordan needs to earn more for buying the video game = (80 - 64) dollars
   = 16 dollars
Amount earned by Jordan per hour working at a pizza shop = $7.75
Let us assume the number of hours Jordan needs to work to save the rest of the money for the video game = x
Then
7.75x = 16
x = 16/7.75
   = 2.06 hours
So it can be said that Jordan has to work 3 hours to save the rest of the money for the video game. If Jordan works 2 hours then he will be short of the required amount. If Jordan works for 3 hours he will have some excess amount in his hand after saving for the video game.

a) six pens and five pencils cost $2.50 while three pens and two pencils cost $1.15 . what will be the cost of a pen and 4 pencils . please help me

Answers

x - pen
y - pencil

$6x+5y=2.5\n 3x+2y=1.15\n\n 6x+5y=2.5\n -6x-4y=-2.3\n --------\n y=\$0.2\n\n 6x+5\cdot0.2=2.5\n 6x+1=2.5\n 6x=1.5\n x=\$0.25\n \nx+4y=0.25+4\cdot0.2=\boxed{\$1.05 }$

Let pen's cost be x and pencil's cost be y.

6x + 5y = 2.50
3x + 2y = 1.15

Thus, 3x = 1.15 - 2y
Therefore, 6x = 2.30 - 4y

Substituting the value of 6x ;

(2.30 - 4y) + 5y = 2.50

or, 2.30 + y = 2.50

=> y = 0.20.

Substituting the value of y ;

6x = 2.30 - 4(0.20)
6x = 2.30 - 0.80 = 1.5
6x = 1.5
=> x = 0.25

Thus, 1 pen costs 0.25 $ and 1 pencil costs 0.20$.

Thus, cost of one pen is 0.25$.
Cost of 4 pencils is 0.80 $

0.25$ + 0.80$ = 1.05$

Dosha is creating a new dessert that has two layers shaped like cones. The inner cone is frozen ice cream and has a diameter of 10 cm and a height of 6 cm. The outer layer is a thin wafer shell, like an upside-down ice cream cone, with a height of 14 cm and the same diameter as the inner layer. Dosha will inject a cream filling into the space.What is the volume of the cream filling? Round your answer to one decimal place and use 3.14 to approximate pi.

Answers

first find volume of inner cone and outer cone then subtract inner from outer

so inner=1/3 (base area) times height
1/3 times (pi times 10^2) times 6
1/3 times 3.14 times 100 times 6
1/3 times 314 times 6
314 times 6/3=628=volume of inner cone

outer cone
base area=314
1/3 times 314 times 14=1456.33

so subtract 628 from 1456.33

1456.33-628=837.3 cm^3

Answer: 1456.33-628=837.3 cm^3
