225-160=65
65/2=32.5
Following this pattern, we do 32.5•5, and then subtract that from 225.
32.5•5= 162.5
225-162.5= 62.5.
My best guess is that the calculator is worth 62.5 dollars in five years.

2x= 6h

?= 3 days or 3×24h

by cross multiplication we have

2x× 72h= 6h×?

?= 2x×72/6 = 24x

So, in three days the bacteria will b 24 times current population.

Maria’s family hosts a barbeque every month in the summer. In May, they bought 3.2 pounds of hamburger and 3 packages of hot dog
Sindrei [870]
Given:

May:
hamburger: 3.2 pounds * 4.25 = 13.60
hotdogs:     3 packages * 4      = 12
Total cost: 13.60 + 12 = 25.60

June:
hamburger: 3.2 pounds * 1 1/2 = 4.8 pounds * 4.25 = 20.4
hotdogs:      3 packages * 1/3    = 1 package * 4        =   4
Total cost: 20.4 + 4 = 24.4

25.60 - 24.40 = 1.20

They spent more on May by $1.20. Choice C.

For every 1 litre of water used to make a medicine, 269ml of sucrose and 47ml of saline solution are used. Express the amount of
leonid [27]

Answer:

1000 : 269 : 47

Step-by-step explanation:

A ratio is a way of comparing the value or amount of one quantity to another.

We are to find the ration of water to sucrose to saline solution, hence, it must remain in that order.

Water : Sucrose : Saline solution

The amount of water is 1 litre (1 * 1000 ml = 1000 ml)

The amount of sucrose is 269 ml

The amount of saline solution is 47 ml

Therefore, the ratio of water to sucrose to saline solution is:

W : S : SS = 1000 : 269 : 47

Since 1000, 269 and 47 have no common factors, that is the simplest form of the ratio.

hodyreva [135]
18 miles = 30 minutes
? miles = 10 minutes
cross multiply
? x 30 = 18 x 10 (180)
? = 180/30
? = 6
the city bus would cover 6 miles in 10 minutes.
