Answer:

24 cm

Step-by-step explanation:

the perimeter is the circumference, the way to go one time fully around the object.

now think, what distances do you have to go when walking around a rectangle ?

well, there are 2 times the length and 2 times the width or breadth. that's it.

P = 2×7 + 2×5 = 14 + 10 = 24 cm

Ipatiy [6.2K]

Answer:

Through open market operations Government can fluctuate the money supply in the economy. One of the short-term effects is to drive the price level from 100 down to 93.3. In short run, decrease in money supply will leads to higher interest rate, this will discourage the investors. Thus, investing and spending will fall which will shift the aggregate demand curve leftward.  

<em>check the attached file for the curve</em>

In long run adjustment in wages tale place and firm will pay lower wage rate to workers. Since nominal wages will decrease overtime causing the SRAS curve to shift rightward. Because unemployment is created in the short run which decreases wages, so supply increase from SRAS to SRAS (1). Long run equilibrium will attain at (8,87.5).

A lidless box is to be made with a volume of 256256 ft cubed 3. Find the dimensions of the box that requires the least amount of
sveta [45]

The optimum shape of such a box is half a cube. The corresponding cube will have a volume of 2×256 ft³ = 512 ft³ = (8 ft)³. Such a box has a square base that is 8 ft on a side. If the height is half that of the cube, it will be 4 ft.

The dimensions of your box will be 8 ft square by 4 ft high.

_____

If the base dimension is x ft, the area (quantity of material) is

... a = x² + 4x(256/x²)

... a = x² + 1024x⁻¹

Then the derivative of area with respect to x is

... a' = 2x -1024x⁻²

Setting this derivative to zero and solving for x gives the value of x for minimum area.

... 0 = 2x -1024/x²

... 512 = x³

... x = 8 . . . . . . . . same as above.

Find the volume of the square pyramid below
Snowcat [4.5K]

Answer:

A

Step-by-step explanation:

The volume (V) of a pyramid is

V = \frac{1}{3} area of base × perpendicular height (h)

area of square base = 4² = 16 and h = 4, hence

V = \frac{1}{3} × 16 × 4 = \frac{64}{3} = 21 \frac{1}{3} ft³

One pump can fill a swimming pool in 72 hours. A second pump can fill the same pool in 60 hours. If
Studentka2010 [4]
I’m not sure but i think 66 hours because both pumps must fill half of the pool which would split the timing for each which would make pump 1 take 36 hours to fill half and pump two take 30 hours to fill the rest. when you add these hours it equals 66. i hope i helped :)
