Part 1= You are shopping for a shirt, and you want to get the best deal. You go to two stores, the first of which is JCPenney. W

DedPeter [7]

Answer:

Macy’s

Step-by-step explanation:

let’s find the cost of each shirt

JCPenny’s: 14.99 x 0.80 = $11.99

11.99 x 1.06 = $12.70

The final cost of the JCPenny shirt is $12.70

Macy’s: 17.99 x 0.65 = $11.69

11.69 x 1.07 = $12.51

The final cost of the Macy’s shirt is $12.51

$12.51 is less than $12.70

So, the Macy’s shirt is the better deal :)

The axis of symmetry for the graph of the function f(x)=3x^2+bx+4 is x= 3/2. what is the value of b

Papessa [141]

Answer:

b = -9

Step-by-step explanation:

The function is given as :

$f(x)=3x^2+bx+4$

The axis of symmetry for this function is x = 3/2

It is required to find the value of b. The axis of symmetry of a parabola is a vertical line that intercepts its vertex at its horizontal coordinate. It can be given by :

$x=\dfrac{-b}{2a}$

Putting x = 3/2 and a = 3 we get :

$b=-2ax\\\\b=-2\times 3\times \dfrac{3}{2}\\\\b=-9$

So, the value of b is -9.

Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.

Viefleur [7K]

Answer:

shading three boxes

Step-by-step explanation:

It is given that :

The body weight of an average adult = 60%

We have to show this by shading the square boxes shown.

There are 5 square boxes in total which makes up 100%.

So divide 100 by 5, we can 20% for each box.

So, 20% + 20% + 20% will give us 60%

Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

This is represented by the figure below.
