The price of an item has been reduced by 85% . The original price was $45. What is the price of the item now.
Kobotan [32]

Answer:the price for the item now it's 6.75


Step-by-step explanation:

Origin price is 45=100% after reduction comes to 85% =x

X stands for the unknown value of the reduction therefore

45=100%

X=85%

45*.85=100x


After calculation you realised the value of x reduction value it's 38.25


Hence, original price is 45 your less from the value reduced 38.25 therefore the value of the item is 6.75

Which must be true of a quadratic function whose vertex is the same as its y-intercept?
BaLLatris [955]

Answer:  Choice A

The axis of symmetry for the function is x = 0.

===========================================================

Explanation:

The vertex is on the axis of symmetry. Since the vertex is on the y axis, this means the y axis itself is the axis of symmetry. The y axis is represented by the equation x = 0. Every point on the y axis has an x coordinate of 0. Example points are (0,2) and (0,5).

This parabola may have 0 roots, 1 root, or 2 roots.

The boy wants to build rectangular beetle cages to study beetle behavior. He wants all the sides on the base of his cages to be
kap26 [50]

Answer:

32 cm by 18 cm

16 cm by 36 cm,

48 cm by 12 cm

24 cm by 24 cm

Step-by-step explanation:

<u><em>The complete question is</em></u>

A boy wants to build rectangular cages. He wants all the sides on the base of his cages to beat least 10 cm long.he also wants the base area to equal 576 cm2. The boy needs help to find all the possible lengths and widths for the base of the cages. He used only whole centimeters, with no fractional parts.what are all the possible dimensions for the rectangular base?

we know that

The number 576 decompose in prime factors is the same that write

576=(2^6)(3^2)

To find out possible side lengths, multiply different combinations of these prime numbers together (make sure each pair adds up to 10)

3x3=9cm                  2x2x2x2x2x2= 64cm  ----> is not a combination (one side is not greater than 10)

3x3x2= 18cm            2x2x2x2x2= 32cm

3x3x2x2= 36cm        2x2x2x2= 16cm

3x2x2= 12cm             3x2x2x2x2= 48cm

3x2x2x2= 24cm         3x2x2x2= 24cm

therefore

32 cm by 18 cm

16 cm by 36 cm,

48 cm by 12 cm

24 cm by 24 cm
