Answer:

88 cm

Step-by-step explanation:

The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.

The area of each rectangle = 36 * 1 1/3

= 36 * 4/3 = 48 cm^2

So the longer side of each rectangle = 48 / 6 = 8 cms

Therefore, the perimeter of the whole figure

= 4( shorter sides ) + 8(longer sides)

= 4*6 + 8*8

= 24 + 64

= 88 cm (answer)

Solve BCD Round the answer to the nearest hundredth

lesya [120]

Answer:

Step-by-step explanation:

The measure of angle D can be found using the Interior Angle Sum of a Triangle.

The angles of a triangle add to 180. This means:

90 + 21 + x = 180.

111 + x = 180

x = 69

The solution is A.

Angle B is smaller than Angle D which means CD will be smaller than BC.

6. For a particular pickup truck, the percent markup is known to be 115% based on cost to the seller. If the seller paid $15,800

Neko [114]

Answer:

<u>53.5 %</u>

Explanation:

You can convert the percent markup into a multiplicative factor in this way:

Base price: 15,800 . . . (cost to the seller)

Percent mark up: 115% . . . (based on the cost to the seller)

Sale price: 15,800 + 115% of x = 15,800 + 115 × 15,800 /100 =

= 15,800 + 1.15 × 15,800 = 15,800 (2.15) = 33,970

The markup is:

Markup = price paid by the seller - cost to the seller = 33,970 - 15,800 = 18,170 (notice that this is 115% of 15,800)

And <em>the percent markup based on the sale price is</em>:

% = (markup / sale price) × 100 = (18,700 / 33,970) × 100 =

= 53.49 %

Rounding to the nearest tenth percent that is 53.5 %.

Dionne can fold 175 packing boxes in 50 mìnutes. Elias can fold 120 packing boxes in 40 minutes. How long will it take each pers

Gre4nikov [31]

<h2>Dionne will fold 210 packing boxes in "60 mìnutes" and</h2><h2>Elias will fold 210 packing boxes in "70 mìnutes".</h2>

Step-by-step explanation:

Given,

Dionne can fold 175 packing boxes = 50 mìnute and

Elias can fold 120 packing boxes = 40 minutes

To find, the total time each person to fold 210 packing boxes = ?

∵ Dionne can fold 175 packing boxes = 50 mìnute

∴ In 1 mìnute, Dionne can fold number of packing boxes = $\dfrac{175}{50}$ = 3.5

∴ Dionne can fold 210 packing boxes = $\dfrac{210}{3.5}$ minutes

= 60 minutes

Also,

Elias can fold 120 packing boxes = 40 minutes

∴ In 1 mìnute, Elias can fold number of packing boxes = $\dfrac{120}{40}$ = 3

∴ Elias can fold 210 packing boxes = $\dfrac{210}{3}$ minutes

= 70 minutes

Thus, Dionne will fold 210 packing boxes in "60 mìnutes" and

Elias will fold 210 packing boxes in "70 mìnutes".
