y=5(14-x)(x) quadratic equation best models the volume of the box .

What is volume of cuboid?

  • Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
  • The volume of a cuboid is found by multiplying the length by the breadth by the height.

Perimeter = 2(width + length) =28

Let x=width of base, then length of base = (28/2)-x = 14-x

Volume of box = length*width*height

=x(14-x)*5  ⇒ 5x(14-x)(x)

Therefore, y=5(14-x)(x) quadratic equation best models the volume of the box .

The Martin’s want to buy a new computer. The regular price is $849. The store is offering a 20% discount and a sales tax of 6% i
kramer

Answer: The total cost of computer would be $719.95

Step-by-step explanation:

I use proportions for these types of problems so we begin with a proportion!

20/100=x/849

100x=16980

x=169.80

Then, after finding how much the discount is, we would subtract it.

849-169.80=679.20

Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.

6/100=x/679.20

100x=4075.2

x=40.75

Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!

Hope this helps! Good luck! (:

Answer:

Other needs =25,2 degrees

insurance = 100,8 degrees

Taxes= 7,2

Housing = 57,6

food= 57,6

childcare = 64,8

transportation = 46,8

Step-by-step explanation:

Its % of 360 degrees so you have to calculate the percentage of each categorie on 360 degrees to find the angles. Exemple, for the Other needs, you take 7% out of 360 degrees and you find that it is equal to 25,2. (7% x360 degrees /100)

A 27​% solution ​( 27mg per 100 mL of​ solution) is given intravenously. Suppose a total of 1,36 L of the solution is given over
a_sh-v [17]

Answer:

Step-by-step explanation:

a.

(1.36 L)/(10 hr) = (0.136 L)/(hr)

Flow rate = (0.136 L)/(hr) × (1000 mL)/L = (136 mL)/(hr)

136 mL × (27 mg)/(100 mL) = 36.72 mg

Delivery rate = (36.72 mg)/(hr)

b.

(136 mL)/(hr) × (13 gtt)/(mL) = (1868 gtt)/(hr)

c.

10 hr × (36.72 mg)/)hr) = 367.2 mg
