Answer:

The number of boxes = 13

Step-by-step explanation:

Given the weight of the delivery person =160 lb

The weight of each box of books=40 lb

maximum capacity of the elevator=710 lb

Let the max number of boxes of books be x. Now the total weight of the boxes and the delivery person should not exceed the maximum capacity of the elevator.

40*x+160

40*x

x

x

Therefore the maximum value of x is 13(since it is an integer).

What is the simplified form of this expression 7(^3sqrt2x)-3(^3sqrt16x)-3(^3sqrt8x)
trasher [3.6K]

Answer:

<h2>7 \sqrt[3]{2x}  - 6 \sqrt[3]{2x}  - 6x</h2>

Solution,

7( \sqrt[3]{2x} ) - 3( \sqrt[3]{16x} ) - 3( \sqrt[3]{8x} ) \\  = 7 \sqrt[3]{2x}  - 3 \times ( \sqrt[3]{2 \times 2 \times 2 \times 2x}  - 3 \times  \sqrt[3]{2 \times 2 \times 2x}  \\  = 7 \sqrt[3]{2x}  - 3 \times (2 \sqrt[3]{2} x) - 3 \times 2x \\  = 7 \sqrt[3]{2x}  - 3 \times 2 \times  \sqrt[3]{2x}  - 3 \times 2x \\  = 7 \sqrt[3]{2x}  - 6 \sqrt[3]{2x}  - 6x

Hope this helps...

Find the midpoint of the line segment joining the points (5,6) and (-1,-6).
kumpel [21]

Answer:

The midpoint is (2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(5+-1)/2 =4/2 =2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(6+-6)/2 =0/2 =0

The midpoint is (2,0)

A cylindrical-shaped container requires 12 cubic feet of soil to be considered full. If a cone with a congruent base and height
stich3 [128]

The statement that describes the volumes of the two figures relate is: <em>The </em><em>volume of the cone</em><em> is 1/3 of the </em><em>volume of the cylinder</em>

Given the following:

Volume of cylindrical-shaped container = 12 cubic feet

Volume of cone-shaped container = 4 cubic feet

Ratio of the volume of the cone to the volume of the cylinder = 4 : 12 = 1 : 3

Therefore the statement that describes the volumes of the two figures relate is: <em>The </em><em>volume of the cone</em><em> is 1/3 of the </em><em>volume of the cylinder</em>

<em />
