Answer:
1) 100 - 2(35) - 2.50 = x
x= $27.50
2) x * 7 + 345 = 1,740.00
x= (1,740 - 345) / 7
x= $199.29
Answer:
If those two line on the side of -27 are there purposefully then they mean absolute value and so that would be positive 27 and on a number line the numbers to the right are greater than the ones on the left
So |-27| is GREATER than -45
The first answer N(t) = 1.95^t
Answer:
B
Step-by-step explanation:
There are 48 flavors and toppings. Since 16 are flavors, 32 are toppings. Dividing the 32 topping equally between 8 children is 4 toppings per child.
32 ÷ 8 = 4
The correct answer is B) 9 m.
The measure of the sector of circle R is 32π/9 m. The measure of the central angle is 80°. This means that the sector is 80/360 = 2/9 of the circle. The area of a circle is given by A=πr², so the area of the sector is A=2/9πr². To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.
Using this same formula for circle S, we will work backward to find the radius:
18π = 2/9πr²
Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²
Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²
Take the square root of both sides:
√81 = √r²
9 = r
