Answer:
45 quarters
Step-by-step explanation:
1. Think of this as the ration equation 9/3=x/15 where x is the number of quarters to play 15 levels
2. To solve the ratio, you need to cross multiply, and then divide
3. Multiply 9 times 15 (135)
4. Divide that number by 3 (45), and that's your answer!
It would be 6 out of 12 chances
Answer:
y = -5x + 4/3
Step-by-step explanation:
m is the slope and b is the y intercept. m= -5 so -5 is the slope and b= 4/3 so 4/3 is the y intercept.
Answer:
approximately 21, when rounded to nearest tenth.
Step-by-step explanation:
First, let's find the measure of angle BAD. Angles BAD and DAC add up to 180 degrees, so 180-57= 123 degrees. Now, let's find the circumference of the circle. The circumference is diameter * π, which is 19.6(π). Then, the ratio is 123/360, so multiply 19.6(π) by 123/360, and you get 21.0381988...... which simplifies to 21 (rounded to nearest tenth)
