Answer:

157.47km²

Step-by-step explanation:

Given the following

base of 18.1 kilometres

height of 17.4 kilometres

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 * 18.1 * 17.4

Area of the triangle = 314.94/2

Area of the triangle = 157.47km²

Hence the area of the triangle is 157.47km²

Step-by-step explanation:

Using Trignometry,

tan77° = Opposite/Adjacent = FG/GE.

Therefore FG = GEtan77°

= (2.6)tan77° = 11.3 feet.

Answer:

.0666

Step-by-step explanation:

Answer:

the answer is 2/15

Step-by-step explanation:

multiply the denominators by each other to get 15

so in 2/3 multiply 3 by 5 and in 1/5 multiply 5 by 3. 2•1 is 2 so you will get 2/15

Answer:

14 children

Step-by-step explanation:

If we know the ration, and we are given the adults, we can set up a proportion in order to solve for the amount of children there are.

5:2=35:x

5x=35*2

5x=70

x=14

There are 14 children

Given:

Jonny and Faheem share some money in the ratio 3:5.

Faheem gets £12 more than Jonny.

To find:

The amount that Jonny gets.

Solution:

Jonny and Faheem share some money in the ratio 3:5.

Let Jonny and Faheem get 3x and 5x.

Different between their amounts is

[tex]5x-3x=2x[/tex]

Faheem gets £12 more than Jonny. It means the difference between their amounts is equal to £12.

[tex]2x=12[/tex]

[tex]x=\dfrac{12}{2}[/tex]

[tex]x=6[/tex]

The amount that Jonny gets is

[tex]3x=3(6)[/tex]

[tex]3x=18[/tex]

Therefore, Jonny gets £18.

Step-by-step explanation:

2*24.50=49 (two shirts)

18.90 (pair of shorts)

49+18.90=67.90

she can spend 70, means she can buy all of those and she still has 2.10  

Answer:

7, 10 and 15

Step-by-step explanation:

Given

[tex]S_1= 3[/tex]  --- Students already enrolled

[tex]Total = 10\ (less)[/tex]

Required

Determine the additional number of students needed for the teacher not to cancel the class

First, we need to calculate the number of students for the teacher to cancel the class.

Represent this with x.

So, we have:

[tex]S_1 + x < Total[/tex]

Make x the subject

[tex]x < Total - S_1[/tex]

Substitute values for Total and S1

[tex]x < 10 - 3[/tex]

[tex]x < 7[/tex]

This means that if less than 7 additional students come to the class, the teacher will cancel the class.

So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)

Answer:

64,512 m3

Step-by-step explanation:

3 1

​  

(base area)(height) =  3 1

​  

(64⋅64)(48)  =65,536

The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.

We know volume for the right square pyramid is given by:

[tex]\rm V= \frac{1}{3} b\times h[/tex]

Volume for the cut off portion:

[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]

v = 1024 cubic meters

Volume for the completer pyramid"

[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]

V = 65536 cubic meters

Volume of the building = 65536 - 1024

= 64512 cubic meters

Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

Given:

s is inversely proportional to t.

When s = 0.5, t = 7.

To find:

The value of s when t=0.8.

Solution:

s is inversely proportional to t.

[tex]s\propto \dfrac{1}{t}[/tex]

[tex]s=\dfrac{k}{t}[/tex]       ...(i)

Where, k is the constant of proportionality.

Putting s=0.5 and t=7, we get

[tex]0.5=\dfrac{k}{7}[/tex]

[tex]0.5\times 7=k[/tex]

[tex]3.5=k[/tex]

Putting k=3.5 in (i), we get

[tex]s=\dfrac{3.5}{t}[/tex]

This is the equation of proportionality.

Putting t=0.8, we get

[tex]s=\dfrac{3.5}{0.8}[/tex]

[tex]s=4.375 [/tex]

Therefore, the value of s is 4.375 when t=0.8.
