Answer:

m =  \frac{p}{(n + 4)}  \\ (n + 4)m = p \\ nm + 4m = p \\ nm = p - 4m \\ n =  \frac{p - 4m}{m} \\ n =( \frac{p}{m} - 4)

<h3><u>n=p/m-4</u> is the right answer.</h3>

Answer:

n = \frac {p - 4m}{m}

Step-by-step explanation:

Given the algebraic expression;

m = \frac {p}{n + 4}

To make n the subject of formula.

Cross-multiplying, we have;

m*(n+4) = p

mn + 4m = p

Rearranging the equation, we have;

mn = p - 4m

n = \frac {p - 4m}{m}

Can anyone help???????????​
Vedmedyk [2.9K]

Given:

The distance between the two buildings on a map = 14 cm

The scale is 1:35000.

To find:

The actual distance in km.

Solution:

The scale is 1:35000.

It means 1 cm on map = 35000 cm in actual.

Using this conversion, we get

14 cm on map = 14\times 35000 cm in actual.

                       = 490000 cm in actual.

                       = 4.9\times 1000o0 cm in actual.

                       = 4.9 km in actual.          [1\text{ km}=100000\text{ cm}]

Therefore, the actual distance between two buildings is 4.9 km.

Step-by-step explanation:

7, HT= \sqrt{8^2 + 15^2} =17 cm

8, S = 1/2.AC.BC.sinC≈28,01 cm^2

9, S =1/2.SR.RT.sin R≈ 3615,7 m^2

Prove:

the area of the ABC triangles is S

sin A = BH/AB

S = 1/2 BH.AC=1/2 sinA.AB.AC=1/2*c*b*sinA

How can you find the area of a two-dimensional composite figure, or the surface area of a three-dimensional composite figure?
goldenfox [79]

Step-by-step explanation:

<u>a. the area of a two-dimensional composite figure</u>

In this situation, we need to draw any necessary segments to view the figure as basic shapes, then:

  • Step 1: add basic shape areas belonging to the composite shape
  • Step 2: subtract basic shape areas NOT belonging to the composite shape

<u>b. the surface area of a three-dimensional composite figure</u>

As we know (3D) composite objects are made of two or more objects put together. To find the surface area of a 3D composite object, we need:

  • Step 1:  find the outside surface area of each object
  • Step 2: add the surface areas together

Hope it will find you well
