Oh freight elevator can hold a maximum weight of 3500 pounds and delivery man weighs 200 pounds is delivering curtains that each
mario62 [17]

Answer:

200+48n\leq 3500

n\leq 66.7

Step-by-step explanation:

  • The freight elevator can hold a maximum weight of 3500 pounds
  • The delivery man weighs 200 pounds
  • Each carton weighs 48 pounds

Let the number of cartons he can safely put on the elevator at one time=n

Total weight of Carton=48n

Since the weight of the man and the cartons combined must not be more than 3500 pounds,

Therefore,an inequality that represents the situation is:

200+48n\leq 3500

We can solve for n if required

200-200+48n\leq 3500-200\\48n\leq 3200\\\text{Divide both sides by 48}\\n\leq66.7

The delivery man can safely carry 66 Cartons.

A square of the side lenght of 6cm has the same area as this rectangle . find the perimeter of the rectangle.
Aleksandr-060686 [28]

Answer:

The perimeter of the rectangle is 26 cm

Step-by-step explanation:

First find the area of the square by multiplying 6 by itself

A = 6 cm * 6 cm = 36 sq cm

Since the rectangle has the same area as the square, we can say that w * 9 = 36 sq cm

w * 9 = 36

Divide both sides by 9 to isolate the variable, w

w * 9 / 9 = 36 / 9

w = 4 cm

The width of the rectangle is 4 cm so now we just use that to find the perimeter of the rectangle

P = 2(9) + 2(4) = 26 cm

How would you find the area or perimeter of this shape?
Fittoniya [83]

The perimeter of a given shape implies the <u>sum</u> of all its <u>sides</u>. While the area of a given shape is the <em>total value</em> of <u>space</u> it would <u>cover</u> on a 2-dimensional <em>plane</em>.

The perimeter of the shape is 104 cm.

The area of the shape is 640 cm^{2}.

The <u>perimeter</u> of a given shape implies the <u>sum</u> of all its length of <em>sides</em>., such that the<u> value</u> of each <em>individual side</em> is summed to a <em>total value</em>.

The area of a given shape is the <em>total value</em> of space it would <u>cover</u> on a 2-dimensional <u>plane</u>. The area of <u>shapes</u> depends on the <em>type</em> of <u>shape</u>.

In the given question, the given <u>shape</u> has 12 <em>sides</em>. Some of these <em>sides</em> can <u>sum</u> up to a given <u>length</u> as shown in the diagram.

So that;

perimeter = 2 + 32 + 10 + 10 + 2 + 32 + 8 + 8

                 = 104 cm

Thus, the <u>perimeter</u> of the shape is 104 cm

ii. The <em>area </em>of the shape = length x width

                                         = 32 x 20

                                         = 640 cm^{2}

Therefore, the area of the given shape is 640 cm^{2}.
