Answer:
1) b⁵⁴
2) 7⁷
Step-by-step explanation:
When you have an exponent raised to an exponent, like in #1, you simply multiply the exponents.
When you are dividing two numbers with exponents and they have the same base, like in #2, you subtract the denominator exponent from the numerator exponent.
Answer:
10 Because if u do 30-10=20 and then 20÷2= 10
Answer:20π
Step-by-step explanation:
equation of the circle
(x+3)² + (y-5)² = r²
now, (-9, -3) lies on it
So, (-9+3)² + (-3-5)² =r²
36+ 64 = r² =100
hence, r =10
So, circumference = 2πr = 20π
Start by listing this until you see that X+Y = 50
X can equal: 4,8,12,16,20,24,28,32,36,40,<u>44</u>
Y can equal: 1.5,3,4.5,<u>6</u>,7.5,9
So...
X=11
Y=4
so... 4 sandwiches were bought, and 11 drinks.
