Answer:
743.25m^2
Step-by-step explanation:
Area of triangle = 1/2bh
= 1/2 x 30 x 26
= 390
Area of semi circle = 1/2 πr^2
= 1/ 2 x 3.14 x 15 x15
=353.25m^2
= 390 + 353.25
= 743.25m^2
Answer:
2/3 is the answer..
Step-by-step explanation:
becaue 2 holes then 2/3s is not filled trust me!!! plz give brainliest and a thanks!!!!
Multiply both the numerator and denominator by 
, which is called the "conjugate" of 
:
Why do we pick this number? Recall the difference of squares factorization:
Now replace 
and 
. Then
So in your fraction, you end up with
Finally, just expand the product.
The two numbers are 12 and 15
<em><u>Solution:</u></em>
Let the smaller number be "x"
Let the larger number be "y"
Given that,
<em><u>The sum of two numbers is 27</u></em>
Therefore, we frame a equation as:
Smaller number + Larger number = 27
x + y = 27 ------ eqn 1
<em><u>The larger number is 3 more than the smaller number</u></em>
Larger number = 3 + smaller number
y = 3 + x ------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 2 in eqn 1</u></em>
x + 3 + x = 27
2x + 3 = 27
2x = 27 - 3
2x = 24
<h3>x = 12</h3>
<em><u>Substitute x = 12 in eqn 2</u></em>
y = 3 + 12
<h3>y = 15</h3>
Thus the two numbers are 12 and 15
