Answer:
total area = 615 sq. in.
Step-by-step explanation:
There are 4 triangles that make up the lateral area. The base of each triangle is 60/4 = 15 in. and the height of each triangle is 13 in. So, the area of one triangle = .5bh = .5(15)(13) = 97.5. The lateral area = 4(97.5) = 390. The area of the square base is 15(15) = 225. The total area = 390 + 225 = 615 sq. in.
You could use Pythagoras Theorem to solve this.
All the points are equidistant from the centre of line AB, therefore it is just the same triangle but rotated. I hope this help but I can show you on paper if you don’t understand that answer :)
A. has 3 number that give it value
b. has 4 (even 0 add to its value)
c. has 3
D. has only 2
e. has 2 , both number add value
f. has 4 value
g also has 4, all numbers give value
hope this helps
Answer:

Number of minutes is 80 minutes
Step-by-step explanation:
Given
The attached table
Calculating the number of copies the machine can make in a minute
Represent number of minutes with m and number of copies with n
First, we need to calculate the ratio of m to n
<em></em>
<em></em>
<em>When m = 5; n = 325</em>


<em>When m = 10; n = 650</em>


<em>When m = 15; n = 975</em>


When we continue for other values of m and n, the ratio remains the same;
So; we make use of
to determine the relationship between m and n
Substitute 65 for Ratio

Multiply both sides by m



This implies that, you have to multiply the number of minutes by 65 to get the number of copies
Calculating the number of minutes to print 5200 copies;
In this case;
Ratio = 65 and n = 5200
So;
becomes

Multiply both sides by m


Divide both sides by 65



<em>Hence; number of minutes is 80 minutes</em>
