Answer:

  • 0.625 cm²

Step-by-step explanation:

<u>Scale factor:</u>

  • k = 1/20000

When applied to the area consider k² as a scale factor.

<u>The actual area:</u>

  • 2.5 hectares = 25000 m² = 25000*100² cm² = 250000000 cm²

<u>The area on the map:</u>

  • 250000000 * (1/20000)² = 0.625 cm²

Two pyramids are similar with a ratio of surface areas of 25:36. Find the volume of the larger pyramid given that the first has
ki77a [65]

Answer:

432m^3

Step-by-step explanation:

The computation of the volume of the larger pyramid is shown below:

Let us assume the volume of the larger pyramid be x

Given that

The ratio of two pyramids is 25:36

We can say that

The Ratio of side = (The ratio of surface area)^\frac{1}{2} = \frac{5}{6}

Now

ratio of volume = (ratio of side)^3 =  \frac{5^{3}}{6^{3}} = 125 : 216

Based on the above information, the calculation is as follows

\frac{125}{216} = \frac{250}{x}

So,

x = \frac{250 \times 216}{125}

= 432m^3

Can someone help me with this question ?
damaskus [11]
Tan52° = x/29

The angle of elevation is 52°, so that must be inside the tan function.

Tan is the ratio of the opposite side to the adjacent side. Jessica’s height is unknown, so we can call that x. The adjacent side of the triangle is the shadow, which is 29’m. Since tan is opposite over adjacent (remember SOH CAH TOA), the fraction must be x/29.
