Answer:
perfect square
Step-by-step explanation:
A perfect square is a number multiplied by itself:
16 = 4^2 = 4 * 4
Answer: 80%
80,000 = 100%
20,000 = 20%
100% - 20% = 80%
Always convert the main number into 100 and follow through with the other numbers
Answer: They can order from 0 to 449 bars, but no more.
Step-by-step explanation:
Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.
The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.

To solve for x, subtract 20 on both sides, we get

Divide 0.40 on both sides, we get
......... → the number of bars that could be ordered, with the shipping costs and their spending requirements must less than 450.
Thus, they can order from 0 to 449 bars, but no more.
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, 1), thus
y = a(x - 2)² + 1
To find a substitute (1, 0) into the equation
0 = a(1 - 2)² + 1
0 = a + 1 ( subtract 1 from both sides )
a = - 1
Hence
y = - (x - 2)² + 1 or
y = 1 - (x - 2)² → A
