The value of the variable is 19 degrees
Answer:
OK so the equation has a exponent so if there is a exponent then you need to multiply. since 227 is the Area and the exponent is 2.
Step-by-step explanation:
Answer:
1109.80 ft²
Step-by-step explanation:
In this case apply the formula for finding area of a circle where the rope tied to the dog will represent the radius of the circle area for the region the dog can explore.
Area of a circle= πr²
radius= r= 18.8 ft
Area of a circle= 3.14*18.8*18.8=1109.80 ft²
Answer:
A: Store A will cost about $1.28 less
Step-by-step explanation:
Okay, let's find the unit rate of cost. To find that for store A, we divide 7.26 by 3, which gets us 2.42. For store B, we need to look for the first intersection. We find that at (20, 50). Let's divide 50 by 20. That gets us 2.50. Let's multiply 2.42 and 2.50 by 16. That gets us 38.72 for store A and 40 for store B. Let's subtract 38.72 from 40. That gets us 1.28. That means store A costs $1.28 less than store B. That makes our answer A.
