Answer: 34 meters.
Step-by-step explanation;
Step One. Find the value of the width. Use an equation with w representing the width and the two values you already have. 9 meters x w = 72 square meters.
Step Two. Solve for width. This is w = 8.
Step Three. Use the value for width in a perimeter formula to calculate the perimeter; 9(2) + 8(2). <em>This is 34 meters for perimeter</em>.
Here, I'll use C for combinations.
There are 15 boys and you need 3 so 15 C 3 ways
There are 30 girls and you need 7 so 30 C 7
and there are 45 total and you need 10 so 45 C 10
The answer is [15 C 3 • 30 C 7] over 45 C 10
so do that on your calculator if you need an actual decimal.
Answer:
9

Answer:9
Step-by-step explanation:
You have three different sizes and three different drinks. Therefore each coffee type can have three different choices 3*3=9
Answer:
C
Step-by-step explanation:
From the equation we know that the center is at (1, 0), which points immediately to choice C. The graph in C is an ellipse with semimajor axis 4 and semiminor axis 3, which agrees with the equation.
