Answer:
6 miles
Step-by-step explanation:
Let's set up a ratio:
We can use "cross multiplication" to solve for x
Cross multiplication is multiplying the numerator of the first fraction by the denominator of the second fraction and the denominator of the first fraction by the numerator of the second fraction.
Divide both sides by 50 to isolate x
Answer: 10.3 pounds of CO2 is produced
Step-by-step explanation:
Assuming there are 30 days in a month, if the microwave is run for 10 minutes per day, then the number of minutes for which the microwave is run in a month is
30 × 10 = 300 minutes
We would convert from minutes to hours
60 minutes = 1 hour
Therefore,
300 minutes = 300/60 = 5 hours
Also,
1000 watts = 1 kW
Therefore,
1500 watts = 1500/100 = 1.5kw
Therefore, the number of kWh is
1.5 × 5 = 7.5 kWh
If 1.37 pounds CO2 per kWh, then
If 1kWh = 1.37 pounds CO2, then
7.5 kWh = 7.5 × 1.37 = 10.3 pounds rounded to the nearest tenth
The answer is -.25 4(-.25) = -1 +6 = 5! Hope this helps!!! :)
Answer:
8.20 grams ; 8.20 cm³
Step-by-step explanation:
At first convert it to m³ from dm³
we know,
1 dm³ =10⁻³ m³
∴ 8.20 X 10⁻³dm3 = 8.20 X 10⁻³ x 10⁻³ m³
=8.20 X 10⁻⁶ m³
<u>m³ to gram :</u>
1 m³ = 10⁶ grams
∴ 8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶x10⁶) grams
= 8.20 grams
<u>m³ to cm³ :</u>
1m³ = 10⁶ cm³
∴8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶ x 10⁶) cm³
=8.20 cm³
Note:
1 cm³ = 1 gram
Answer:
$2.9
Step-by-step explanation:
<u>Given the following data;</u>
Total cost of package = $14.50
Number of package = 5
To find the cost of each package;
Substituting into the equation, we have;
Cost per package = $2.9
<em>Therefore, the cost per package of bottled water is $2.9.</em>
