Let x be the number of red balloons and y the number of yellow balloons used, then
x + y ≥ 40
y ≥ 25
<u>Answer:</u> The final answer must have only one decimal place.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures present in a number that expresses the magnitude of a quantity to a specific degree of accuracy.
We are given:
An addition problem having values (34.530 g + 12.1 g + 1222.34 g)
<u>The rule that is applied for the addition and subtraction is:</u>
The least precise number present after the decimal point determines the number of significant figures in the answer.
For the given problem, the least precise number after the decimal is '1'
Evaluating the value: (34.530 g + 12.1 g + 1222.34 g) = 1268.97 ≈ 1269.0
Hence, the final answer must have only one decimal place.
Answer:
Step-by-step explanation:
<u>Let the score is x. The average is:</u>
- (83 + 56 + 94 + x)/4 = 82
- x + 233 = 4*82
- x = 328 - 233
- x = 95
In the question, it is already mentioned that the water tank holds = 24,000 gallons
In the given question it is also mentioned that the need is to find the time required to use 2/3 of the total water that the tank holds.
So the need is to find the amount of water that equals 2/3 of the total water in the tank.
Then
Quantity of water that needed to be used = [24000 * (2/3)] gallons
= 16000 gallons
In the problem it is also mentioned that the average rate of consumption per day is 650 gallons.
So
650 gallons of water used in = 24 hours
16000 gallons of water will be used in = [(24/650) *16000] hours
= 590.77 hours
So the time required to consume 2/3 of the total water in the tank is 590.77 hours.
Answer:
Step-by-step explanation:
<u>Unit rates are:</u>
- Brand A glue = $2.08/8 = $0.26 per oz
- Brand B glue = $1.62/6 = $0.27 per oz
Brand A glue is cheaper, so is the better buy
