Mathematics

6 0

Answer:

  10 mm/cm

Step-by-step explanation:

The conversion factor always has a value of 1. It is a fraction with the numerator equal to the denominator -- only the units are different.

The numerator units are the units you're converting <u>to</u>: millimeters. The denominator units are the units you're converting <u>from</u>: centimeters.

You know that 1 cm = 10 mm, so when you arrange the fraction as described, the conversion factor you're multiplying by is ...

  \boxed{\dfrac{10\,\text{mm}}{1\,\text{cm}}}

Greg needs at least $1.60 in stamps to mail a package. He has 28cent stamps and 4cent stamps. He can use no more than twenty 4ce
lapo4ka [179]

19 4-cent stamps and 3 28-cent stamps should be used.

Given that Greg needs at least $ 1.60 in stamps to mail a package, and he has 28cent stamps and 4cent stamps, and he can use no more than twenty 4cent stamps as he only has one book left, to determine how many stamps to use should be made the following calculation, through a linear function:

  • (0.04 x 20) + 0.28X = 1.60
  • 0.80 + 0.28X = 1.60
  • 0.28X = 1.60 - 0.80
  • 0.28X = 0.80
  • X = 0.8 / 0.28
  • X = 2.85

  • (3 x 0.28) + 0.04X = 1.60
  • 0.84 + 0.04X = 1.60
  • 0.04X = 1.60 - 0.84
  • 0.04X = 0.76
  • X = 0.76 / 0.04
  • X = 19

Therefore, 19 4-cent stamps and 3 28-cent stamps should be used.

Jade spent ⅓ of her math homework time working on word problems. What fraction of an hour did she spend working on word problems
Tems11 [23]

Answer:

If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour

Step-by-step explanation:

Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).

1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.

7nadin3 [17]
The correct answer is the larger one is 30 and the smaller one is 12 because 42-18 gives you 24 so you do 24/2 you get 12 so you add 18 to one of the 12s and you get the answer as 12 and 30
