Answer:
225
Step-by-step explanation:
(90000÷325)×65=18000
18000÷80=225
reading rate of 225 words per minutes
Answer: H
Step-by-step explanation:
40 minutes is not a full hour so you need to convert this to hours
40 minutes / 60 minutes = 2/3 of an hour
So a car driving at the rate of 34 2/3 mph will go
34 2/3 * 2/3 = Miles in 40 minutes
40 * (4/9) = ?or
160/9 = ? or
17 7/9 Miles
Answer:
The volume each of the four barrels of the same size will be at least 47.5 liters.
Step-by-step explanation:
Let the volume of each of the four barrels is v liters.
Now, the amount of water that can be held in the fifth barrel is 10 liters. The total capacity of holding water for the 5 barrels combines is at least 200 liters.
So, from the above-given information, we can write the inequality to determine the volume of each of the four barrels will be
10 + 4v ≥ 200
Solving this we get,
4v ≥ 190
⇒ v ≥ 47.5
Therefore, the volume each of the four barrels of the same size will be at least 47.5 liters. (Answer)
If this is what you mean..?
In order to do this you would work backward from the answer.
You have x = 25 and ant to include and addition. As we are working backwards, we use the opposite operation to addition - subtraction. We'll make it an easy number so we will subtract 15 to get to 10.
So far it looks like 10 = 15 + x
Now, to include a division, we want to do the opposite again, multiplication. Pick any number to multiply 10 by - for this example we'll choose 7.
7 x 10 = 70
Now we can write out the equation -
70/7 + 15 = x
No brackets are required as Division comes before addition in BIDMAS.
An alternate choice would be to have x the other side of the '='
To do this, multiply x by a number of choice (for example 3) to make the divison section of the equation. This makes 75. This can be written as a fraction. 75/x = 3
Next, for the addition, whatever happens on one side, the exact same happens on the other. Pick any number to add on (e.g. 5) and re-write the equation.
75/x + 5 = 8
Sorry if this doesn't make perfect sense
