Answer:40%.
Since the student got 60% correct, the remaining percentage would be the part they got incorrect.
I got 60% by translating 9/15 into a decimal and moving the decimal point to create a percentage.
Hope this helps!
Step-by-step explanation:
Answer:
D) a hyperbola
Step-by-step explanation:
IMO, the image is not helpful, as it suggests the ends of the curve are nearly parallel to each other. In fact, the ends of the curve asymptotically approach straight lines parallel to the sides of the cone. That is, there are asymptotes that form an X shape. This is a characteristic of a hyperbola.
___
A parabola is formed when the plane cuts the cone parallel to one side. That cut plane only intersects one nap of the cone. At a shallower angle yet, one gets an ellipse. Parallel to a base, one gets a circle.
Answer:
120 square in
Step-by-step explanation:
The formula for area of a triangle is:
base × height ÷ 2
Plugging your triangle in to the formula, we have:
12 × 20 ÷ 2 = 120
Ratio of girls to boys is 3:2....added = 5.....this means that 3/5 of the total students are girls and 2/5 of the total students are boys.
so if there are 50 students...
3/5(50) = 150/5 = 30 girls
2/5(50) = 100/5 = 20 boys
