Answer:
A cone has one -third times the volume of a cylinder with the same base and altitude. <u>True</u>
Let us do it by converting the 0.4 to a fraction, it has one decimal, so we'll use one zero at the denominator.
and 9.21 to a fraction as well, two decimals, thus two zeros at the denominator then,
Answer:
Greatest possible number of solutions of these set of equations are 2
Step-by-step explanation:
We have been given two functions in the question.
x² + y² = 9
9x + 2y = 16
We know that the equation of circle is given by:
(x - h)² + (y - k)² = r²
However, if (h, k) is equals to (0, 0), the equation of circle becomes:
x² + y² = r²
Which is similar to the fist equation
x² + y² = 3²
Hence first equation is a circle.
As the second equation is a linear equation, it is simply a line.
We know that a line passing through the circle can intersect it at only 2 points.
Where points of intersection between both circle and line shows the solution.
So.
There are 2 possible solution to this set of equations
Total the number of tenth graders: 12 + 14 + 8 = 34 total.
Now divide the number of tenth graders who speak Spanish by the total number of tenth graders:
12 / 34 = 0.3529
Multiply the decimal answer by 100 to get the percent:
03529 x 100 = 35.29%
Round to the nearest tenth = 35.3%
The answer is the first choice.
Answer:
The error is: The solution shows the Sam's age and the problem asked for Micaela's age.
Solution fixed: 
Micaela is 17 years old now.
Step-by-step explanation:
The error is: The solution shows the Sam's age and the problem asked for Micaela's age.
To fix the error, you can set up these equations based on the information given:
Solve for "s" from the first equation:
Substitute this equation into the second equation:
Now you need to solve for "m":
Micaela is 17 years old now.
