How much cardboard will be needed to make the box? 4 feet by 3 feet with a height of 2 feet
sergiy2304 [10]

Answer:

52 ft²

Step-by-step explanation:

When you are calculating the amount of cardboard needed to make a box, you are trying to the the <u>surface area</u>.

The formula for surface area of a rectangular prism is:

SA = 2(lw + hl + wh)

The dimensions for the box are written l X w X h (length times width times height).

We know:

l = 4

w = 3

h = 2

The units for surface area is the unit squared. Feet squared is ft². Be sure the include the units.

Substitute these numbers into the formula. When solving, solve in the BEDMAS order (brackets, exponents, division and multiplication, addition and subtraction).

SA = 2(lw + hl + wh) u²

SA = 2((4*3) + (2*4) + (3*2)) ft²      Multiply within each smaller bracket

SA = 2(12 + 8 + 6) ft²          Add inside the brackets

SA = 2(26) ft²        Multiply

SA = 52 ft²         Final answer

Therefore 52 square feet of cardboard will be needed to make the box.

How fast was a driver going if the car left skid marks that were 48 feet long on dry concrete? (The coefficient of friction is 1
Savatey [412]

Answer:

B) 38 mph

Step-by-step explanation:

s = √(30df)

s is the speed the car was traveling (in mph)

d is the distance the car skidded (in feet)

f is the coefficient of friction

s = √(30 x 48 x 1.02)

s = 38.32492661... = 38

I really need help!!!!
dezoksy [38]

Answer:

150 bikes, $10,500 minimum manufacturing cost

Step-by-step explanation:

5x^2 - 1500x + 123000 is represented by a parabolic graph that opens up.  You could easily estimate the x value at which C(x) is at a minimum, as well as the smallest C(x) value.

Or you could do this problem algebraically by finding the vertex of the parabola.  The results MUST be the same as before.

                                                                                                 -b

The equation of the axis of symmetry of this curve is x = ---------

                                                                                                  2a

... which here is    x = 1500

                                   --------- = 150 units (150 bikes)

                                     2(5)

Evaluating C(x) (see the problem statement) at x = 150 leads to finding the minimum cost.  I like to use synthetic division to evaluate polynomials.  Here, the divisor would be 150 and the coefficients of the quadratic would be

5   -1500   123000

Setting up synthetic division, we get:

150   /  5      -1500         123000

                       750        -112500

         --------------------------------------

           5        -750           10500

The remainder is $10,500.  This is the minimum cost of this manufacturing operation.

What does x equal? Dpsewbskdye
Mice21 [21]

Answer:

x = 7

Step-by-step explanation:

27 = 7x + 6 - 4x      (Given)

27 = 3x + 6             (Simplify)

27 - 6 = 3x + 6 - 6  (Subtract 6 on both sides)

21 = 3x                    (Simplify)

21/3 = 3x/3             (Divide 3 on both sides)

7 = x                        (Simplify)

1) CD is the perpendicular                   1) Given

bisector of AB

2) AD=DB                                              2) Definition of bisector

3) CD=CD                                              3) Reflexive property

4) mAngleCDA=90                               4) Definition of perpendicular

5) mAngleCDB=90                               5) Definition of perpendicular

6) mAngleCDA=mAngleCDB               6) Substitution property

7) Corresponding parts of each           7)  SAS

triangle are congruent                                (side-angle-side)

8) AC=CB                                               8) The two triangles are ............................................................................congruent so

                                                                   the corresponding parts ............................................................................are

                                                                   congruent.
