Answer:
69%
Step-by-step explanation:
If the diameter is increased by 30%, it is effectively multiplied by the factor ...
1 + 0.30 = 1.30.
Volume is proportional to the square of the diameter, so the larger can's volume is ...
(1.30)² = 1.69
times that of the smaller can. That is, 0.69 = 69% of the volume of the smaller can has been added to make the volume of the larger can.
The volume of the larger can is 69% more than that of the smaller can.
Answer:
20 stacks of 5 pennies weight 0.33 pounds
Step-by-step explanation:
<u>First, we need to calculate the weight in kilograms of 20 stacks of 5 pennies:</u>
20 stacks= 0.0075*20
20 stacks= 0.15 kg
<u>Now, we can determine the weight in pounds:</u>
1kg = 2.2 pounds
0.15kg = ?
Weight in pounds= (0.15*2.2)/1
Weight in pounds= 0.33 pounds
20 stacks of 5 pennies weight 0.33 pounds
The answer is 174 because you can simply do 97+78
Answer:
The equation has no solution; therefore, the system of equations has no solution
Step-by-step explanation:
we have
-----> equation A
-----> equation B
we know that
If after applying the linear combination method, Heather arrived at the equation 0 = 60
then
The reason is because both lines are parallel, therefore the system of equations has no solutions
<u>Verify</u>
isolate the variable y in the equation A
--------> the slope is 1/3
isolate the variable y in the equation B
--------> the slope is 1/3
Remember that
If the slopes are equal the lines are parallel
so
The system of equations has no solutions
