Answer:
True False True
Step-by-step explanation:
1. A circle has 360 degrees in its interior. 360 - 130 (this is given) degrees = 230 degrees. This means it's TRUE
2. The area of the shaded sector is the degrees in the central angle that contains the sector, multiplied by the area of the circle. This means that the area is pi*r^2*angle. The radius is 10, and the angle is 230 degrees, so the answer is 100*230/360 pi = 23000/360 pi, which simplifies to 575/9 pi. This is FALSE.
3. The area of the shaded sector is area of the circle - area of the shaded sector. The area of the circle is pi r^2, which is 100 pi. 100 pi - 575/9 pi = 325pi/9, so this is TRUE

Answer:
Ice rental at the local skating rink is $150 for 2h. Skate rental is $3 per person. The Grade 8 class went skating. All students rented skates. The total cost was $231. How many students went skating?
Step-by-step explanation:
We see that the ingredients and their respective measurements serve 6 people. There are numerous ways you can solve this, here's one way.
You need the 15 servings and you have the recipe for 6. You can use these values to create a scale factor. To do this, you just divide the intended number of servings by the number of servings the recipe gives you.
This leads to:
15 servings / 6 servings = 2.5
Since this scale factor has no units (the unit of "servings" cancels out through division), you can apply it to all measurements. Meaning, you can multiply each measurement by the scale factor of 2.5.
This gives you:
75 g butter
2.5 onions
5 tablespoons flour
3 liters tomato juice
1200 ml milk
