The correct response is ;
<span>multiply the term number by 2, subtract 1 from the result, multiply by 2 times the term number, and divide the result by 2.
if term number is x,
the number in the pattern for xth term is ;
multiply term number by 2 - 2x
subtract 1 - 2x - 1
multiply by 2 times the term number - (2x-1) * 2x
divide by 2 - (</span>(2x-1) * 2x)/2
so first term x=1
((2*1-1) * 2*1)/2
2/2 = 1
second term x = 2
((2*2-1) * 2*2)/2
(3*4)/2 = 6
third term x = 3
((2*3-1) * 2*3)/2
5*6/2 = 15
fourth term x= 4
((2*4-1) * 2*4)/2
56/2 = 28
Therefore the above response shows the correct pattern
Answer:
You can buy 7 waffle cones.
Step-by-step explanation:
Let sundae = x
Let waffle cones = y
4.25x + 3.75y ≤ 50
4.25 (5) + 3.75y ≤ 50
21.25 + 3.75y ≤ 50
3.75y ≤ 28.75
y ≤ 7.666666666
* round to the nearest whole to get 7
Answer:
The measure of the angle Y in given triangle is 120 º.
Step-by-step explanation:
Here, in ΔXYZ
∠X = 34 º , ∠Z = 26 º
By, ANGLE SUM PROPERTY of a Triangle:
Sum of all the interior angles in any given triangle is always 180 º.
⇒ ∠X+ ∠Y + ∠Z = 180 º
or, 34 º + ∠Y + 26 º = 180 º
or, ∠Y = 180 º - 60 º
⇒ ∠Y = 120 º
Hence, the measure of the angle Y in given triangle is 120 º.
Answer:
4 / 15
Step-by-step explanation:
Fraction that likes stuffed animal = 16/20
4/12 of fraction who like stuffed animals prefer shaggy ones ;
Fraction of second grade that like stuffed shaggy animals ;
4/ 12 of 16/20
(4 /12) * (16 / 20)
(4 * 16) / (12 * 20)
= 64 / 240
= 4 / 15
