Answer:
1.150 seconds or 2.5 minutes
2. 0.2km
Step-by-step explanation:
1. 1.5 x 1000=1500
1500/10=150
150/60=2.5minutes
2. 60mins = 36km -Divide both sides by 60 to get how far he would go in 1 minute/60 secs
1min/60secs=0.6km -Divide both sides by 3 to get how far he would go in 20 secs
20secs=0.2km
Answer:
each individual bag of rice weighs 9-pounds.
Step-by-step explanation:
Based on this information we would need to create an equation for the weight of each individual bag of rice. We are told that a 64lb package contains 4 boxes so...
64 lbs. = 4 boxes
Each box contains a 7-pound bag of beans and 1 bag of rice. Since we are told how much the bag of beans weighs we can multiply this by the number of boxes to calculate its total weight from the package...
7 lb. * 4 = 28 lbs.
Now we know that the bags of beans in the package weights 28 pounds. We now subtract this from the total weight of the package to find the total weight of the bags of rice in the package.
64 lbs. - 28 lbs = 38 lbs.
We can see now that the 4 bags of rice in the package weighs a total of 28 pounds. Therefore, we can divide that total by 4 to calculate the weight of each individual bag of rice...
28 lbs. / 4 = 9 lbs.
Finally, we can see that each individual bag of rice weighs 9-pounds.
The answer for the exercise shown above is the second option, the option B, which is: B. In step 3, the addition property of equality was applied incorrectly.
The explanation is:
To solve this problem you must apply the proccedure shown below:. You have the followinwg equation:
<span>
4(m-3)+5(m+2)=m+9
Let's review the steps:
4m-12+5m+10=m+9 (step 1)
9m-2=m+9 (step 2)
8m =7 (step 3) (There is a mistake, because: 9m-m=9+2</span>⇒8m=11)
<span> m=11/8 This should be the step 4</span>
So,
Proportion basically means, that something is proportional
Example: A rope's length and weight are in proportion.
It's in proportion because the longer the rope, the more the weight
so, let's say
A popcorn machine costs 20 an hour
And in order to rent one, you have to pay $32 dollars
So you pay 32 for the machine, then 20 for every hour you use it
the number of hours used WOULD be proportional to the cost because
the more hours used, the more the cost
your final answer: YES it is proportional
C
3/2 is equal to the cost of $1.50. Each movie is $1.50, so the amount of movies (m) would have to be multiplied by $1.50. Then to calculate the price, you add $18. This would mean the equation looks like
c= 3/2m + 18
