I'm pretty sure that the answer would be 7.50 because if you do ($18.99+$29.50)x2, you would get $7.50.
Answer:
21
Step-by-step explanation:
For something to be a function, the input (x value) can only have one output (y value). If an x value has more than one y value, it is not a function.
A.) When x = 1, it has 5 y values. This is not a function
B.) -2 and -1 have two y values. This is not a function
C.) 1 and 2 have two y values. This is not a function
D.) Each input has only one output. This is a function. (Inputs can share the same outputs)
Your answer is D
Answer:
So that means length of the bike is approx 5.7 rulers.
Step-by-step explanation:
the question says to estimate how many 12-inch rulers will be about the same length as a bike. In other words we have to measure the length of bike by in terms of ruler like 3 ruler length or 5 rular length etc.
Type of bike is not mentioned so i'm going to use bicyle.
From internet I found that approx lenght of a bike ( bicycle) is = 68 inches.
Given that 1 ruler = 12 inches
So number of rulers that can fit into 68 inches can be found by dividing 68 by 12
68/12 = 5.7
Using the formula for the perimeter and area of rectangle, the dimensions are: Length = 19 m; width = 9 m.
<h3>What is the Perimeter and Area of a Rectangular Shape?</h3>
Perimeter = 2(length + width)
Area = (length)(width).
Let x represent the length and y the width, therefore:
2(x + y) = 56 --> eqn. 1
xy = 171 --> eqn. 2
Rewrote eqn. 1
x + y = 56/2
x = 28 - y
Substitute x = (28 - y) into eqn. 2
171 = (28 - y)y
171 = 28y - y²
171 - 28y + y² = 0
y² - 28y + 171 = 0
Factorize
(y - 9)(y - 19)
y = 9 and y = 19
Therefore, the dimensions are: Length = 19 m; width = 9 m.
