1) Work out what 1/5 of 12 is
To do this, we divide 12 by 5
12/5 = 2.4
2) Multiply 2.4 by 15
2.4 x 15 = 36
<em>If you don't like decimals, you can also do it this way...
</em>
This can be rewritten as 15 x 1/5 x 12
Multiplications alone can be performed in any order
1) Work out what 1/5 of 15 is
1/5 of 15
15/5 = 3
2) 3 multiplied by 12
3 x 12 = 36
Answer:
C) Kite
Step-by-step explanation:
The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has <em>only one </em>right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.
Therefore, the answer is C) Kite
Hope this helps!
Answer:
(0,0) and r=3
Step-by-step explanation:
To find the radius and center rewrite the equation in vertex form 
.
First move x and y to the other side so they have positive signs. Then move 9 across to the other side too.
Here you can see there is no h or k meaning h=0 and k=0. The radius is the square root of 9 which is 3.
The question is to find the sum of the 15thb first term ( i goes from 1 to 15)
for i =1, the first term is 4
for I=15, the last term = 74
Sum of the terms of a AP = (first term + last term)(number of terms/2)
₁₅
∑F(n) = (4+74)(15/2) =585
i=₁
